Abstract: A biomass stove has an outer chamber formed by a continuous side wall which is connected to a bottom wall. An air inlet is formed in the bottom wall for allowing introduction of air into the interior of the outer chamber. A fuel basket, also formed as a continuous side wall attached to a bottom wall, is located within the outer chamber. In the fuel basket, near the bottom of the fuel basket, a grate is positioned. First and second reflecting members are positioned below the grate within the fuel basket. Air inlets are located along the bottom periphery of the fuel basket with primary air flowing up through the air inlets and over the reflecting members and through the grate into a fuel supply which can be located within the fuel basket on the grate. One or more of the primary stoves can be suspended in a support housing to form an appropriate multi-burner stove.

The telephone circuit includes an optical receiving element optically coupled with the network circuit optical emitting element. The telephone circuit optical receiving element has a reversed biased pn junction. The telephone circuit further includes an optical emitting element which is optically coupled with the network optical receiving element.

Abstract: A voice actuated toy robot receives commands via a radio transmitter and receiver, and in response to receipt of these commands propogates a signal through a CPU. Initially the toy is programmed by storing records of commands in a memory which is associated with the CPU. Upon further receipt of identical commands, the CPU scans the memory and upon finding a match between a record in the memory and a new command, the CPU activates a switch associated with the record in the memory so as to set the switch. A mechanical interogator is capable of cycicly interogating a plurality of switches each of which corresponds to one of the records in the memory. Upon interogation of the switches, if it is determined a signal is present at one of the switches, the interogator ceases interogation and a mechanism is set so as to propogate motion from a motor to an appendage driving wheel or the like of the robot to produce an output in response to the audio command which was received.

Abstract: A blade holder for holding a disposable ice shaving blade on an ice resurfacing machine has an attachment member which is attached to an appropriate support member on the ice resurfacing machine. The attachment member has an elongated "V" shaped groove which extends across the transverse width of the attachment member. A triangular shaped retaining member mates against a surface in the .-+.V" shaped groove on the attachment member. A surface on the attachment member and a wall on the retaining member which are spaced apart from each other in a parallel relationship when the retaining member mates with the attachment member, form a cavity for excepting and retaining a disposable ice shaving blade. The retaining member is connected to the attachment member utilizing a plurality of attaching elements such as appropriate bolts or the like. These attaching elements are independent from the structure which is utilized to attach the attachment member to the appropriate support member on the ice resurfacing machine.

Abstract: A toy wheeled vehicle includes an inertial element located so as to move between two positions. A spring is associated with the inertial element to accelerate it from its first position to its second position. When the element reaches its second position the force of the acceleration is transferred to the vehicle chassis and the vehicle chassis "jumps" in response to the force.

Abstract: A toy, as for instance a simulated toy computer, has a housing with a window formed in the housing. Behind the window is an indicia strip or carrier which has indicia located on its surface. Positioned in front of the indicia strip is a lenticular screen. The lenticular screen is connected to a mechanism which mechanically moves the lenticular screen with respect to the indicia. Movement of the lenticular screen in front of the indicia gives the appearance that the indicia, in fact, is moving. Actuator keys are provided on the housing for advancing the indicia strip and for activating the movement of the lenticular screen.

Abstract: A lamp has an elongated hollow neck with a lighting fixture attached to one of its ends. The other of its ends is attached to a main bracket. The main bracket includes one of either a set of elongated parallel ribs or a set of elongated parallel grooves. A secondary bracket is attached to a support surface and includes the other of either the elongated ribs or the elongated grooves. The main bracket is attached to the secondary bracket by sliding the ribs into the grooves to temporarily attach the lamp fixture to the secondary bracket so at to hold the lamp fixture in a temporary position against a support surface on which the secondary bracket is attached.

Abstract: The compound 2-.beta.-D-ribofuranosylthiazole-4-carboxamide is used to treat malignant tumors in warm blooded animals. Esters of this compound such as 2-(2,3,5-tri-O-acetyl-.beta.-D-ribofuranosyl)thiazole-4-carboxamide and 2-(5-O-phosphoryl-.beta.-D-ribofuranosyl)thiazole-4-carboxamide are also useful for treating tumors in warm blooded animals.

Abstract: A toy is constructed to include two unique linkages with the first linkage including a series of links located in a sequential array with each link pivotally connected to its next immediate adjacent neighbor and every other link operatively connected such that each link can pivot with respect to its neighbor and motion of a link pivotally connected to one side of a link is communicated to the link pivotally connected to the other side of that same link. This allows the linkage to propagate motion along the totality of the sequence in response to movement of any one link. The second linkage includes a first member which is pivotally connected to a rotating crank pin and connected at its upper end to a second lever which is pivotally connected to a body on which the crank pin rotates.

Abstract: A toy suitable for attaching to infant furniture has an elongated track having ends with connecting members positioned on the ends of the track for connecting to an appropriate portion of the infant furniture, such as the side rails of a crib. A housing is mounted along the track. The housing includes a motor and associated components which drive the housing along the track. A stop member is located on each of the ends of the track. The housing includes a sensing lever which is engaged against the stop members on the respective ends of the track, so as to switch the direction of travel of the housing along the track. The housing also includes a musical device and a gear train driven by the motor for producing a constant output to drive the musical device.

Abstract: A remote control toy includes a remote housing and a main housing. The remote housing has a transmitter and a signal generator associated with the transmitter. A plurality of function switches govern the signal generator. The transmitter outputs a signal which is encoded by the signal generator to reflect which switch or switches is activated on the remote housing. The main module includes a receiver to receive the signal from the transmitter. The receiver removes the encoded signal and outputs it to a decoder. Depending upon the signal received, the decoder outputs to one or more of its output ports which are connected to appropriate output devices located on the main module. One of these includes a tape drive which carries a tape therein, and which is capable of recording a sequence of control functions transmitted by the remote module to the main module.

Abstract: A toy vehicle and track utilizes a track which is formed of a plurality of sections which are connectable together. At least some of the track sections are round tubular elements. The vehicle has only two wheels. When positioned over the track, the vehicle is supported by the two wheels and, at most, a further contact point between the underside of the vehicle and the track.

Abstract: An inflatable balloon capable of being delivered to a site within a body via a catheter or the like, includes on its surface a composition. The composition is capable of inducing the formation of a thrombosis followed by invasion of capillaries and fibroblasts to the thrombosis and subsequent scar formation. Scar formation fixedly adheres the balloon at its placement site to permanently locate the balloon at this placement site.
