Abstract: A lottery ticket is printed onto a conventional paper, card or similar substrate to provide game information printed on the substrate and game data printed on the substrate where some or all of the game data is covered by a removable covering which can be removed by the player generally by scratching a latex covering layer to expose the covered data for playing the game. In addition, a battery is printed on the substrate together with printed conductive paths, a powered element such lights or sound or a changeable ink formed on the substrate and a switch responsive to an action on the substrate by the player, generally scratching of the covering layer for conducting power from the battery to the powered element.

Abstract: An electric power distribution and control apparatus has a stack of conductive plates each having a plurality of spaced contact pads and conductive traces connecting the contact pads to others of the pads. At least one of the plates has contact terminals for connection to electrical components for supply of electrical current. An array of contact pins pass through holes in the plates at a respective one of the contact pads such that the array of pins provides connection between selected contact pads of different selected conductive plates. An electronic system for connection to a communication bus is added to the above known system by providing a main circuit board having the electronic components thereon, a mapping circuit board having a plurality of contact pads thereon arranged for connection to respective ones of the array of pins and a header having a male pin array and a female socket array connecting the main printed circuit board and the mapping circuit board.

Abstract: Intrusion detection of one section only of a multimode fiber uses a light signal launched into the fiber at a location spaced from the source through a single mode fiber to establish a narrow spectral width, under-filled non-uniform mode field power distribution in the fiber. A small portion of the higher order signal modes at the a second location also spaced from the destination is sampled by a tap coupler and monitored for transient changes in the mode field power distribution which are characteristic of intrusion to activate an alarm. The active signal of a multimode optical fiber is monitored for both signal degradation and transient power disturbance patterns that could indicate fiber damage or physical intrusion. A translator can be provided in an existing optical fiber system in which the data signals are translated in wavelength and/or launch conditions to optimize the monitoring signals in an otherwise non-optimized system.

Abstract: A wear shield is attached to a cutter bar and is formed from a molded wear body having a front mounting portion bolted onto the guards of the cutter bar by the guard mounting bolts with recesses for the guard fingers and a front edge of an upper planar mounting surface clamped onto the guard bar. A rear covering portion is cantilevered rearwardly from the front mounting portion underlying a bottom plate of the cutter bar for engaging the ground so as to underlie and protect the bottom plate. Resilience in the wear shield forces the rear part against the bottom plate of the cutter bar to avoid the necessity for a rear fastener. A series of the wear shields is arranged side by side across the cutter bar with two side edges each for locating adjacent a side edge of a next adjacent wear shield.

Abstract: A coupling device that requires no manual actuation to achieve coupling features a locking bolt movable along a hole extending into a mouth of a hook body to secure a coupling pin therein. A control lever pivotally connected to the locking bolt opposite the mouth end is biased toward a locked position in which motion of the locking bolt is blocked. To engage the coupling pin and the hook mouth, the coupling pin and an operable pin extending through the hollow locking bolt are brought into contact. This causes an end of the operable pin opposite the mouth to push against the control lever to unlock it from the latching position. The coupling pin pushes the locking bolt out of the mouth so that it can pass by further into it, at which point the lever and bolt return to the locked positions to secure the coupling pin inside.

Abstract: An oven for baking a batch of parts has a housing having side walls and a top wall defining a closed container with a closed top end and an open downwardly facing bottom end. Loading/unloading occurs at the bottom end onto a carriage raised to the top end where baking occurs. On each side is provided an array of heating elements below the top. A shield is located in front of the heating array so as to block direct radiation onto the parts to prevent over-heating as the carrying arrangement passes the heating array to be unloaded. The shield generates an upwardly flowing air stream to carry the heat to the top. The heating elements are mounted with their lower end in a connection box with a collar and insulated heat shield above the box to keep the electrical connections cooled.

Abstract: In nuclear magnetic resonance experiments, Cartesian electronic feedback is used to reduce substantially in transmission and/or reception the deleterious effects of sample-mediated and direct interactions between coils in an array of transmitting and/or receiving coils. The feedback is also used with single or multiple coils to maintain at essentially constant values the relationship between an input transmitter voltage and the magnetic resonance flip angle, and the relationship between transverse nuclear magnetisation and the strength of the free induction decay signal presented by a receiver for analysis, regardless of factors such as sample electrical conductivity.

Abstract: A crop header has a cutter bar with generally horizontal flail disks driven about generally spaced upright axes. At least two of the disks are mounted outwardly of a discharge opening and the outermost disk carries an impeller and at least one additional impeller is mounted inwardly and rearwardly of the outer impeller to carry the crop inwardly. The impellers are formed of angularly spaced bars which are inclined inwardly to a center waist to form an “hour glass” shaped impeller. A transfer roller transfers the crop upwardly and rearwardly from the disks to the nip of a pair of conditioner rolls and is at least as large as the bottom roll and carries high ribs forwardly inclined for an aggressive action on the crop with its axis above the cuffing plane and its uppermost edge of the ribs at or above the axis of the bottom roll.

Abstract: A transport system for a crop header includes a first and a second wheel arrangement on the header frame adjacent a respective ends for acting as a stabilizer when the header is in the operating position and movable to a transport position for transporting the header when removed from the vehicle in a transport direction generally longitudinal of the header frame and at a right angle to the working direction with each being mounted on the header frame for rotation of a rolling direction of the first wheel arrangement between the working position and the transport position, in which the rolling direction is along the transport direction. Each of the wheel arrangements includes two parallel wheels coupled together.

Abstract: A crop harvesting header has a cutter bar with a plurality of generally horizontal flail disks mounted thereon for driven rotation about generally upright axes spaced along the cutter bar. At least one of the disks is mounted outwardly of the discharge opening and carries an “hour glass” shape impeller to carry the crop inwardly. A pair of conditioner rolls is mounted in the discharge opening and a transfer roller is mounted behind the disks and in front of the nip for transferring the crop upwardly and rearwardly from the disks to the nip. The transfer roller is of the same diameter as the bottom roll and carries high ribs preferably forwardly inclined for an aggressive action on the crop. The roller is mounted with its axis above the cutting plane and its uppermost edge of the ribs at or above the axis of the bottom roll.

Abstract: A heat transfer fluid medium (25) within the closed system is arranged to boil to form a vapor in the evaporation section (12) and such that release of heat from the condensation section (11) to the fluid to be heated (4A) causes the vapor to condense to liquid in the condensation section (11). The conduit forms a loop (10) and back flow in the loop (10) is prevented by providing a trap (27) of liquid in the conduit at a position adjacent to or at the evaporation section (12). The flow around the loop (10) at high speed sufficient to carry all condensate forwardly is caused solely by application of energy to the system by the heat source (21) without mechanical pumping. Inert gases are collected immediately upstream of the trap (27) and can be purged therefrom.

Abstract: Content networking provides a content-based routing architecture, in which a virtual overlay network called the “virtual content network” is superimposed over the physical network. The content network contains content routers as the nodes and “pathways” as links. The content-based routers at the edge of the content network may be either a gateway to the client domain or a gateway to the server domain whereas the interior ones correspond to the content switches dedicated for steering content requests and replies. The pathways are virtual paths along the physical network that connect the corresponding content routers. The tags for tagging content requests at the ingress points are designed to incorporate several different attributes of the content in the routing process. The path chosen for routing the request is the optimal path and is chosen from multiple paths leading to the replicas of the content.

Abstract: A telecommunications multimode optical fiber is secured against intrusion by detecting manipulation of the optical fiber prior to an intrusion event. Pulses are injected using a launch arrangement which generates a narrow spectral width, under-filled, non-uniform mode field power distribution in the multimode optical fiber and Fresnel reflections and Rayleigh backscattering from the pulse are detected at the transmit end to monitor the modal power distribution in the fiber which changes on manipulation of the fiber. The Rayleigh backscattering time sliced data can be stored in a register until an intrusion event is detected. The detection is carried out by a modal power distribution detection system which includes an optical coupler to tap off a portion of the light which contains the higher order signal modes.

Abstract: Fuel for supply to the carburetor of an engine is vaporized in a container having a first and second chamber divided by a transverse heating plate against which the fuel is impacted from a fuel injection nozzle a form vapour therefrom so be discharged under pressure from the vaporization through an outlet duct for supplying the vapour from the first chamber to the engine. The heating plate is heated by a heating liquid heated by a thermostatically controlled electrical heating element within the second chamber. The injector is controlled by a pressure switch in the first chamber.

Abstract: The center sickle overlap arrangement of a sickle type mower for a cutter bar that include a pair of sickles for reciprocating motion where each sickle is essentially half the length of the cutter bar for reduced forces and vibrations for high speed cutting. In the center, the sickle blades overlap at only guard and the blade of one sickle is inverted and co-operates with a top ledger surface of the associated guard so that both the blades are in proper shearing arrangement with the respective guard ledgers. Further the top ledger surface is adjustable to allow clearance adjustment to ensure tight clearance between all sickle cutting surfaces and guard ledgers. Further the arrangement ensures that all crop is cut between sickle sections and guard ledgers rather than between a pair of sections on the opposing sickles.

Abstract: An apparatus for picking, conveying, stacking and bundling lumber pieces from the ground for example for removing stacked support lumber during laying of a pipe line comprises a tracked vehicle to which is attached a frame carrying a transport conveyer along the side of the vehicle forwardly and downwardly toward the ground. At the forward picking end is provided a picker roller for lifting the lumber pieces from the ground. On one side of the picker roller is provided a drive conveyer which is generally vertical and operable in forward and reverse direction to orient the pieces. On the side opposite to the drive conveyers provided a vertical blade with a rearwardly inclined inner portion which blade can pivot inwardly to push the lumber pieces toward the drive conveyer and to enclose and squeeze the pieces to a position inward of the side of the conveyer.

Abstract: The goal was to automate and optimize the shaping and positioning of a shape-specific/conformal voxel that conforms to any volume of interest, such as a cranial lesion, to allow conformal voxel magnetic resonance spectroscopy (CV-MRS). We achieved this by using a computer program that optimizes the shape, size, and location of a convex polyhedron within the volume of interest. The sides of the convex polyhedron are used to automatically prescribe the size and location of selective excitation voxels and/or spatial saturation slices. For a spherically-shaped, phantom-simulated lesion, CV-MRS increased the signal from the lesion by a factor of 2.5 compared to a voxel completely inside the lesion. CV-MRS reduces the voxel prescription time, operator subjectivity, and acquisition time.

Abstract: A pull-type crop harvesting machine has a header carried on a frame mounted on ground wheels with a hitch arm extending from the frame over the header to a hitch connector of a tractor. The hitch arm is mounted for pivotal movement about a generally upright axis such that in a first position the tractor tows the frame in echelon to one side and in a second position the tractor tows the frame in echelon. There is provided connecting assembly for connecting the forward end of the hitch arm to a hitch connector of the tractor and a mechanical connection from the PTO of the tractor to a pump for hydraulically driving the cutting assembly. The connecting assembly provides three axes of pivotal movement for up and down, tilting and side to side movement of the header relative to the tractor.

Abstract: A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. It can be driven cab forward in a working mode with a header on the forward end. It is rotated to engine forward in the transport position for more stable higher speed travel. The driven wheels are driven by hydraulic motors each having their own drive pump the output of which is controlled by a cam plate. The speed control is effected by a manually operable lever through a servo-cylinder which locates a speed control arm moving both cam plates to the set position. In a maximum speed position both cam plates are engaged against a stop. The steering is effected by moving the cam plates differentially to drive the wheels at different speeds. The piston rod of the servo-cylinder includes a spring relief so that the speed control arm can back off from the maximum position by moving the servo-cylinder body when steering in the maximum speed position.

Abstract: A pull-type crop harvesting machine has disk cutter carried on a frame mounted on ground wheels with a hitch arm extending from the frame over the header to a hitch connector of a tractor. The hitch arm is mounted for pivotal movement about a generally upright axis such that in a first position the tractor tows the frame in echelon to one side and in a second position the tractor tows the frame in echelon. The disks are hydraulically driven by a pump at the front end of the hitch arm and a motor at the frame with the hydraulic circuit including a sump tank defined by a hollow interior of the hitch arm and a cooling radiator defined by a tubular frame member which is preferably located at the disk drive as a support therefore as it is cooled by the air flow from the disks and contact with the crop and carries a low volume of fluid.
