Abstract: A method of joining a plurality of elongate log members using mortise and tenon joinery includes the step of forming mortise sockets in the log members at a controllable depth relative to a longitudinal central axis of the log members. Log members having tenons formed thereon for connection between two mortise bearing log members can thus be standardized and interchangeable with one another even when an outer surface of the log members is irregular in profile. A device for forming mortise sockets and tenons on log members in a reproducible manner includes a pair of work holders which define a longitudinal axis of the log member. A mortise cutter and a tenon cutter are supported for movement relative to the work holders for controllably forming the mortise sockets and tenons in a log member relative to the longitudinal central axis of the log member.

Abstract: A tree stand for supporting a cut tree in an upright position by its trunk features a sheet of flexible resilient material cut to form a plurality of retaining flaps extending inwardly from a perimeter portion of the sheet toward a centre thereof such that the retaining flaps will flex away from the perimeter portion of the sheet under forcing of a cut end of the tree's trunk against the center of the sheet to allow passage of a portion of the trunk therethrough while resiliently biasing back toward the perimeter portion of the sheet to engage a periphery of the tree's trunk. A support structure defines a base and supports the sheet at a distance upward from a plane of the base such that the tree's trunk passing through the sheet is held by the retaining flaps in a position projecting upwardly away from the plane of the base.

Abstract: Described herein is the use of a modified human chemokine, GS-CXCL8(3-73)K11R/G31P or G31P in the treatment of a number of diseases or disorders, including but by no means limited to pulmonary disorders, inflammatory diseases and disorders, cancers and surgical/ischemia reperfusion applications.

Abstract: A header assembly for a combine harvester includes a header carried by an adapter on the feeder house of the combine and on a pair of gauge wheels which can be adjusted from inside the cab to change a height of the cutter bar from the ground. This is used in combination with an Automatic Header Height Control so that the main suspension is adjusted to carry approximately 90% of the header weight, the header is dropped on the ground until the gauge wheels contact the ground, and causes the header to “float” with respect to the main carrier frame and the AHHC is set so that the combine feeder house stops lowering when a pre-set amount of header to adapter separation (float) is achieved with the AHHC operating to maintain this set amount by controlling the height of the feeder house.

Abstract: A structural support component such as a head clamp for use in imaging of a part of a patient using Magnetic Resonance and X-ray imaging is formed of different materials each of which has an Aluminum equivalence factor of less than 10 mm and generally less than 6 mm and is arranged such that the presence of the structural support component in an imaging zone of a magnetic resonance imaging system when generating the image does not generate any visually determinable distortion in the image. The materials can be epoxy resin combined with a glass fiber substrate for easily machined parts, polyphenylene sulphide with random fiber reinforcement using glass fibers for high wear parts and polyurethane foam or Polymethacrylimide foam shaped to form a required member and covered on its outer surface with a layer formed from aramid fibers for elongate parts.

Abstract: An apparatus for treating waste water comprises a mixing chamber including mixing members therein for mixing waste water and treatment chemicals therein and a separating chamber at the outlet of the mixing chamber for separating the flocculated contaminants and to provide a supply of clarified water. In a preferred embodiment, the chemicals are injected at sequential locations along an injection tube for sequential mixing of the chemicals with one another in the injection tube prior to the chemicals being injected and mixed into the mixing chamber for mixing with the waste water.

Abstract: An intake nozzle for the inlet pipe of a pump has a vertical duct with a downwardly facing mouth and a surrounding disk shaped intake portion with a bottom surface which faces a flat surface such as a floor or tank bottom to take liquid from the floor down to a shallow depth. The bottom surface is shaped with a flat outer part and an upwardly and inwardly curved inner part converging to the mouth. The surface is shaped and spaced from the flat surface with annular areas defined therebetween so that the liquid enters the peripheral edge slowly and accelerates up to an inner edge of the flat portion and then remains at constant velocity from the inner edge of the flat portion through the mouth and the pipe to the intake of the pump.

Abstract: A crop header has generally horizontal flail disks mounted for driven rotation about generally upright axes. A pair of conditioner rolls is mounted in a discharge opening and a transfer roller is mounted behind the disks and in front of the nip. At each end, two disks are mounted outwardly of the discharge opening each rotating so that its blade moves inwardly and each carries an impeller to carry the crop inwardly. A third disk is arranged so that a line forward of the end of the discharge opening intersects the third disk inward of the axis of the third disk. The third disk rotates so that its blade moves outwardly so that the crop tends to pass between the second and third disks. A pair of impellers are mounted behind the second disk and move inwardly to carry the cut crop to the discharge opening.

Abstract: A belt system convertible into and out of a sit harness configuration for selective use as a harness or a utility belt features a pair of leg loops and a waistband equipped with a quick release buckle. Support straps projecting from the leg loops are arranged for releasable engagement to the waistband and releasable engagement to one another so that the releasable engagement to one another when also engaged to the waistband provides a second closure thereof so that the waistband remains closed by the connection between the support straps even if the quick release buckle on the waistband is inadvertently disengaged. Using only a single waistband, the belt system provides a quick release function when used only as a utility belt, yet avoids the hazard of having the waistband open by inadvertent release of the quick release waistband buckle during use as a harness.

Abstract: Objects are sorted according to specific gravity by illuminating the objects with near-infrared light with different wavelengths. Measurement of the light absorbed by each object at the different wavelengths permits a dry matter content of the object to be determined. Specific gravity can then be determined using a predetermined correlation between dry matter content and specific gravity. A sorting mechanism responsive to determination of specific gravity by the controller separates the food objects into at least two different groups corresponding to different specific gravity.

Abstract: A telecommunications optical fiber is secured against intrusion by detecting manipulation of the optical fiber prior to an intrusion event. This can be used in a non-locating system where the detection end is opposite the transmit end or in a locating system which uses Fresnel reflections and Rayleigh backscattering to the transmit end to detect and then locate the motion. 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 polarization detection system which includes an optical splitter which is manufactured in simplified form for economic construction. This uses a non-calibrated splitter and less than all four of the Stokes parameters. It can use a polarimeter type function limited to linear and circular polarization or two linear polarizers at 90 degrees.

Abstract: A crop harvesting header includes a cutter bar mounted on a frame carrying a plurality of generally horizontal cutter disks. The cutter bar includes a first longitudinally extending hollow gear case and a second longitudinally extending hollow gear case divided at a position along the length of the cutter bar so as to form first and second separate sections. Each gear case includes a gear train of spur gears to drive the cutter disks. On each section the outermost disk is connected to an upstanding drive shaft with a right angle gear box connected to an upper end with a drive transfer shaft connecting the first and second gear boxes, an input hydraulic drive motor to the first gear box and an output shaft and the second gear box for driving the conditioner.

Abstract: A suspension for a cab base on the frame of a swather tractor includes four dampened springs at the four corners with three links each pivoted on one end of the frame and the other end on the base. The links include two parallel links in the fore and aft direction parallel to the mechanical speed control link arm and one side to side link which constrain movement of the base against fore and aft movement and side to side movement parallel to the mechanical steering control link arm. This arrangement restricts movement of the base while allowing roll and pitch movements of the cab structure with the links arranged such that steering and ground speed are substantially unaffected when the cab moves on the suspension.

Abstract: Vine plants are layered along a row of vine plants supported in growing media in a vine crop by a vine planet supporting system suspended from an overhead building structure locating the vine crop therein. The system includes a track extending in a longitudinal direction along the row of vine plants spaced above the growing media. A spool body supporting a string wound thereon is associated with each vine plant to support the vine plant extending along the string. A carrier body slidable along the track supports each spool body on the track. The spool bodies are coupled to the track such that the spool bodies are each arranged to unwind the string therefrom responsive to displacement of the spool body with the respective carrier body in the direction of the row of vine plants.

Abstract: A roof for a large diameter grain bin is formed by roof rafters inclined from a top of the wall to a top ring, with sheet metal panels in an upper row extending from the ring to a circular bottom edge and a lower row extending from a circular top edge to the wall. A circular bracket of Z-shaped cross section is carried on the rafters by upstanding support legs and provides an upper flange engaging the bottom edge of the upper row and a lower flange engaging the top edge of the lower row and an interconnecting web portion. One or both rows are supported at a mid point on a cylindrical tube bent to form a circle butting the panels and supported from the rafters on leg members which include a center strap which can be bent around the tube and two legs bolted to the rafters.

Abstract: An agronomic carrier coated with an acidifying agent and a method for preparing same is described.

Abstract: A lift-type turbine comprising at least three blades at circumferentially spaced positions is supported for rotation about a vertical axis. Each blade has an airfoil shape to generate a torque about the axis responsive to wind across the blades. A support comprising cables under tension is connected between adjacent ones of the blades to extend generally circumferentially about the turbine. Accordingly a minimum number of parts form the structure of the blades while minimizing the drag produced during rotation thereof due to the support members lying in a common circumferential path. The tension of the support members can support the blades in a pre-stressed condition to optimize the shape and performance thereof.

Abstract: An end gate assembly of a dump box comprises an end gate panel supported for pivotal movement about a lower pivot axis of a pair of lower latch assemblies in a first released position and about an upper pivot axis of a pair of upper latch assemblies in a second released position. A common actuator is arranged to release both upper latch assemblies in the first released position of the actuator and is arranged to release both lower latch assemblies in the second released position. The common actuator communicates between the latch assemblies on opposing sides of the end gate panel through a connecting member extending across the gate opening below a floor of the dump box.

Abstract: Euthanasia of birds is carried out by locating a tool on the neck of the bird and crushing the neck between two co-operating members each having a front face for engaging the neck which is sufficiently blunt to prevent cutting of the skin of the neck during the crushing action so as to prevent escape of blood from the neck with the members being held separated at an end of the crushing action to prevent severing of the neck. The members can be driven together for example by hand pressure or on a frame by a foot lever or can be provided as a pair of counter-rotating wheels.
