Abstract: A self-propelled vehicle, primarily for children, comprising rigid frame having elongated seat and leg rest, and backrest integrally formed with and making an internal angle with the seat rest which may be slightly greater than 90 degrees. Beneath the seat adjacent apex of the angle, the frame is mounted on supporting means journalled on an axle which connects a pair of enlarged drive wheels. In normal operating position, the leg rest is supported above the ground by a first caster-like wheel. A similar second caster-like wheel is mounted to an externally projecting support near upper end of the backrest, which in normal operating position is held off the ground. The vehicle is propelled forward in a linear direction by operating the drive wheels either by a system of foot pedals or hand cranks. In another modification, in which the position of the seat is lowered, the drive wheels are rotated manually by knobs near the periphery.

Abstract: Apparatus for indicating if any one of a plurality of sensors detects a malfunction in a heating and cooling system. In response to a sensor detecting a malfunction, a local alarm coupled thereto, a common alarm coupled to all sensors, and a telephone dialing and message conveying device are activated. Signals provided by each sensor to a single coil that activates the common alarm and the dialing and message conveying device are prevented from being conveyed to a local alarm coupled to another sensor by including the coil in a rectifier bridge arrangement. If a malfunction corrects itself or is corrected, the local alarms and common alarm are switched off and reset to permit indication of a subsequent malfunction. The dialing and message conveying device, local alarms, and common alarm can be selectively inhibited. In the event of failure of a primary a.c. power source, a d.c. source is automatically activated to provide power.

Abstract: The invention relates to a technique and instrument comprising a relay rod for performing subcutaneous placement of silastic tubing or vascular grafts from incisions in different parts of the body, more particularly, peritoneovenous shunts or peripheral arterial bypass. The relay rod, which is of rigid non-toxic material, comprises a receptor bore near the tip of its head for threading through the end of the silastic tube or vascular graft. A pair of longitudinally-extended grooves, distal to the receptor bore, accommodate the end portions of the silastic tube or vascular graft, which are secured in place parallel to the rod axis by a pair of ties which rest in circumferential grooves near the upper and lower ends of the longitudinal grooves. The distal end-portion of the rod comprises a shaft and a striated handle to facilitate gripping. The relay rod, with the silastic tube or the vascular graft secured in place thereon, is passed subcutaneously between incisions in different parts of the body.

Abstract: A first fault locater system includes a plurality of monitored switches, each connected across a separate electrically isolated input terminal in circuit relation with an optical signaling means which lights up when a fault is detected in the monitored switch. Each signaling device is optically coupled to a separate silicon controlled rectifier which becomes conducting in response to the optical signal. The output from each silicon controlled rectifier is fed through gating circuits to initiate operation of amplifying and reversing means which imposes a negative bias on each silicon controlled rectifier when a first fault is detected. The negative bias serves to disable each of the monitoring circuits except the circuit detecting the first fault, which remains operated, until reset.

Abstract: A shield for facilitating ventilation of the interior of a motor vehicle, comprising a sheet of transparent semi-rigid plastic material with a flange along its upper edge containing sharp rib or barb-like protrusions near the top for fastening the upper edge of the sheet into a window trough, and a curved skirt with a flange extending outwardly from its lower edge. This keeps out rain and snow while allowing air to pass in and out of the vehicle by means of convection currents. The shield is preferably made of flexible material adapted to be cut with scissors to fit any sized window in the vehicle.In one embodiment, the flange along the upper edge is U-shaped, and flat along the top. A plurality of small metal T-shaped locks are permanently held in the flat top to lock the device into a window trough upon rotation of the locks. This embodiment also includes a row of louvered openings spaced-apart along its length to allow air to pass in and out of the vehicle.
