Abstract: A lateral transfer apparatus for an overhead conveyor comprises generally horizontally extending, side-by-side load tracks for receiving load-bearing trolleys for movement along a first track, and for movement along a second track. A transfer shuttle unit has a normal position aligned with the first track and provides a continuation thereof, and a transfer position aligned with the second track to provide a continuation of the second track. An actuator connected with the shuttle unit shifts it between the normal and transfer positions thereof at an acute angle to the tracks, thereby transferring trolleys to a position aligned with the receiving track for movement therealong.

Abstract: An ankle support has a tubular sock-like elastic sheath which, in use, is slipped over the foot and ankle of a wearer and extends upwardly over the lower leg, the sheath thereby having lateral and medial sides and a posterior end for receiving the heel of a wearer. Heel locks are provided by lateral and medial elastic locking straps secured to the sheath at a bottom portion of the posterior end of the sheath, and at a rear portion of the sheath (back of the heel) above the posterior end. The action of the two locking straps locks the heel of the wearer against lateral and medial movement. An elastic wrap on the sheath over the foot and ankle of the wearer overlies the lateral and medial portions of the locking straps to provide a lift to the heel.

Abstract: A conveyor is powered by a rotating, generally horizontal drive tube or shaft engaged by angularly disposed trolley wheels, in which trolleys support the conveyed products or materials above the drive tube and clear of any parts of the conveyor structure that would interfere with the desired path of travel. Each of the trolleys is provided with load wheels which ride on load rails above the drive tube and associated drive wheels, thereby providing a structure upon which a platform or other support may be mounted for bearing the transported products.

Abstract: A method of producing a dimensionally stable, fire-resistant fabric including the steps of spinning yarn from wool and fire-resistant synthetic fibers, weaving the yarn to form a fabric, and dimensionally stabilizing the fabric to produce a textile that passes aircraft manufacturer specifications.

Abstract: An electrical cord locking connector joins electrical cords in series and presents a streamlined profile that minimizes interference in restricted spaces through which the cords must be fed to service a job site. The connector joins the ends of successive cords utilizing the outwardly projecting shoulder provided on the female socket of one cord in cooperation with a latch member on the male end of the connecting cord to lock the two cords together.

Abstract: An electrical cord locking connector joins electrical cords in series and presents a streamlined profile that minimizes interference in restricted spaces through which the cords must be fed to service a job site. The connector joins the ends of successive cords utilizing the outwardly projecting shoulder provided on the female socket of one cord in cooperation with a latch member on the male end of the connecting cord to lock the two cords together. A cord provided with a female end terminating in a replacement cord cap is provided with a socket presenting a generally circular face and an outwardly projecting shoulder at the face for engaging a releasable latch member of a mating plug, thereby preventing separation of the plug and socket under force until the latch member is disengaged.

Abstract: A railroad signal system interlocking is automatically tested. A control point interface corresponding to a predetermined function of the interlocking has an isolated section and a control section. The isolated section is connected with the interlocking and has a normal, inactivated state during operation of the interlocking, and an activated state for testing the interlocking by detecting an electrical characteristic representing the status of the predetermined function executed by the interlocking. The control section drives the isolated section to its activated state and receiving an output from the isolated section in response to the detected electrical characteristic, and delivers a status report.

Abstract: A traffic radar utilizes digital signal processing (DSP) to determine targets based on signal strength histories. From these histories, a target vehicle having the strongest Doppler return signal is identified and its speed is displayed, and a target vehicle having the highest frequency return signal is identified and its speed is displayed. The traffic radar may also display the relative strength of the strongest return signal and the relative strength of the highest frequency return signal, thereby showing a comparison of the strengths of the return signals from the target vehicles.

Abstract: A food container has an airplane configuration provided by a cardboard-like sheet having a plurality of spaced fold lines defining a number of panels that are folded along the lines and assembled to provide an airplane-like body having food compartments therein. The panels that extend to the tail of the fuselage are especially configured to provide a unitary tail fin and associated stabilizer that present the tail configuration.

Abstract: A modular multi-port manifold and fuel delivery system includes a plurality of ports in fluid communication with corresponding compartments of a fuel delivery vehicle, a collector conduit common to the ports, a control valve associated with each port to control flow of the fuel product from the associated compartment to the collector conduit to deliver the product, and a control system for operating each of the control valves.

Abstract: In a drive system for an overhead conveyor, a first drive shaft presents a path of travel for a trolley, and a second drive shaft spaced from the first drive shaft provides a continuation of the path of travel. A flexible drive cable spans the gap between the shafts and interconnects the terminal end of the first shaft with the receiving end of the second shaft to transfer torque thereto to rotate the second shaft. The cable comprises spiral wound strands joined together to preclude unraveling thereof and thus the second shaft may be driven by the first shaft when their longitudinal axes are not collinear.

Abstract: A method of forming a container for food or other items having a model vehicle configuration is provided that accurately depicts the contours and dimensions of the vehicle to enhance its appeal. An elongated, cardboard-like sheet is presented that is die cut to fold into a three dimensional model of the vehicle. The sheet's first end is folded along a first pair of transverse fold lines and secured in a position to present an open cabin, rear deck and tail of the vehicle, whereby the open cabin may provide the container for food and other items. The sheet's central portion is folded upwardly along a pair of longitudinal fold lines to present the sides of the vehicle, and the second end portion is folded along a second pair of transverse fold lines and secured in position to present the hood and front windshield of the vehicle.
