Abstract: The derailleur includes a relatively long, torsion-resisting bar (29) extending below and generally along one of the two rear wheel-supporting bicycle frame members (15). In a simple embodiment, the front end (31) of said bar is held by a fastener secured to the bicycle frame adjacent the housing of the pedalling axle. The holder prevents the bar from rotating about its long axis. The rear end (57) of the bar is movable transversely of the frame member by a remote control actuator. The bar carries a drive chain transfer member (55) and a chain take-up device (59) which serve to transfer the drive chain from one to another rear drive sprocket, while taking up the slack in the chain. In a preferred embodiment, the chain take-up device (59) comprises an elongated member extending along and below the bar, movable longitudinally along and guided by said bar and carrying at its rear end a drive chain tensioning member (67). The elongated member is biased rearwardly by an elastic cord (69). The bar is movable back and forth under the action of a remote controlled cable and its rear end carries a hook (45) selectively engaging anyone of several positioning recesses (53) made in a plate fixed to the frame member. The recesses are disposed side by side along an edge of a slot (47) made in the plate and through which the hook (45) extends. The slot is transversely inclined being parallel to the envelope of the rear drive sprockets. Longitudinal movement of the bar positions the drive chain transfer member in alignment with the selected drive sprocket.

Title: Reversible protector for a work member
Inventor: CORNELIUS ERWIN D
IPC: E02F9/28
Filed: 1993-09-15
Abstract: Reversible protectors are normally utilized to protect the leading edge of a work member from high wear during use. It is also advantageous to have a reversible protector that can be secured to a work member even though the work member may be composed of several components which are welded together thus adversely affecting the tolerances between the various components. In this subject arrangement, a reversible protector is provided and adapted to be mounted on and secured to a work member. The reversible protector has recesses located in the lower end thereof which, when assembled, are in mating engagement with protuberances on the work member. This mating engagement secures the lower end of the reversible protector to the work member. A pair of aligned openings are provided near the other end thereof which aligns with a transverse hole in the work member for receiving a retaining mechanism therethrough. The protuberances on the work member are protected from wear during use by respective lugs on the reversible protector that are located, when in use, directly adjacent the protuberances. The lugs also protect aligned openings in the reversible protector since the aligned openings are located behind and adjacent the respective lugs.

Patent CA-2108448-A1 (CA)
Inventor: GEFFROS MIKE
IPC: B26D7/08
Filed: 1991-04-26
Abstract: A method of cutting stacked layers of compressible material utilizing a steel rule cutting die. An open cell foam member (18, 20) is placed in the area between spaced portions of the cutting die (16) to define a flat upper surface substantially flush with the sharpened upper edge (16a) of the cutting die. The stacked layers (22) of compressible material are placed on top of the foam member (18, 20) and on top of the sharpened upper edge (16a) of the die and the upper platen (10) of the associated press is Powered to precompress the stacked compressible layers (22) prior to the cutting operation by the die. The foam member ( 18, 20) is an open cell member and has a compressibility such that it maintains a flat upper face ( 18a, 20a) flush with the upper cutting edge of the die during the precompression of the layers (22) and thereafter moves downwardly in a smooth translatory manner to allow the layers (22) to be moved downwardly through the cutting die. The invention methodology avoids distorsion of the fabric pile during the cutting and allows the cutting of even very high stacks of compressible fabric without substantial variation in the shape or length of the cut pieces and without any substantial beveling of the edges of the cut pieces.

Title: Scanless tv transmission system
Inventor: GRUENBERG ELLIOT L
IPC: H04N21/438
Filed: 1992-12-17
Abstract: A scanless TV transmission system is used for transmitting and storing graphic or other information requiring significantly less band width and memory than is currently required. A simultaneously available ensemble of information can be transmitted over a narrow band channel that is limited only by the rate of time change of the entire ensemble of transmitted bits, i.e. for television or motion video the limit is the persistence of vision. Reduction in band width reduces the power required for transmission. To attain these goals, a bit generator and operator, a switched invertor (using an amplifier, transmission loop and filter), a switch invertor, a lowpass filter, an amplifier, another transmission link and a filter are utilized.

Abstract: A LAN cable identifier for testing and identifying copper-conductor LAN cables in conjunction with a LAN cable test instrument is provided. Series combinations ofresistors and diodes allow for both resistance measurements and polarity determinations for selected pairs of conductors of the LAN cable. Resistance values are chosen to allow for identification of each combination in order to diagnose wiring errors and to identify the particular LAN cable identifier. In addition, capacitance measurements are accommodated with minimal contribution to measurement error by careful orientation of the resistors and diodes so that the diodes may be reverse biased by a d.c. bias voltage provided by the LAN cable test instrument. The reverse biased diode junctions contribute only a small amount of shunt capacitance to the measurement.
