Abstract: A system is provided with vehicles for Under-way Vehicle transfer where railway depot cars run on track flush in runways for buses or other highway vehicles to drive parallelly into bottom and side openings, berths, in the cars while moving at train speed along the runway and be lifted and lowered in their berths for transfer of passengers to and from the train nonstop. The buses have an alignment arm at each front (both ends are front) for the driver to extend into the opening and apply pressure on the front face of the berth on the train so the bus driver can detect steady alignment by reading a pressure gauge before turning to enter the opening. The arm is pushed into the bus as the bus reaches alignment under the berth and turns the bus wheels parallel with the train if the driver has not. The bus floor is at or near the height of the depot car floor when set on end ledges in the berth by retracting the bus wheels or lowering end brackets to lift the bus for quick exchange of passengers with the train.
Abstract: Erosion of elements of the ossicular chain in the middle ear, resulting in hearing loss, is corrected by creating a bridge between the eroded elements, employing a bone cement formed as a paste of a self-hardening material, which is molded into an elongated bridge, secured at its two ends to the elements to be bridged, and supported in its desired position until the material hardens to fuse the two elements, at which time the support may be removed. The material is preferably hydroxyapatite cement, bone source, or similar material, such as ionomeric bone cement. These materials strongly bond to the contacting bone and may stimulate bone in-growth, resulting in osseointegration. The apparatus for forming the bridge consists of a reservoir of the bridge material in liquid or paste form connected to a bridge supporting tube. The tube is preferably placed in contact with the two elements to be bridged and the bone source material is injected into the tube using a manually actuated plunger until the tube is full.
Abstract: A flexible connector for vibration isolators, dynamic vibration absorbers, and other vibration control devices for mechanical systems which is composed of streamlined elastomeric resilient elements with nonlinear load-deflection characteristics. These elements are embedded, possibly together with inserts, into a soft matrix which maintains relative positioning of the resilient elements and inserts while not significantly influencing deformation characteristics of the resilient elements. The inserts define the external shape and modify deformation characteristics of the connector, if necessary.
Abstract: A fuel injection system for multi cylinder engine employs a plurality of separate computing circuits for generating variable width control pulses to fuel injectors. Each channel actuates at least one fuel injector during more than 50% of an engine cycle. To derive the start times for these four pulses, a counter is advanced in timed relation to the operation of the engine by pulses from the ignition primary circuit. To control the phase of the firing pulses relative to the cycle time of the engine the counter is reset once each engine cycle by a pulse derived from one of the spark plug leads.
Abstract: A mechanism for receiving elongated articles such as dowel pins, etc., from a bulk source is disclosed which separates the pins and positions them for ejection and insertion by a ram driven driver tool. The mechanism includes a rotary feed cylinder having a plurality of pin receiving chambers extending in directions tending to converge and arranged circumferentially about the feed cylinder axis. The feed cylinder is adapted to receive pins into each chamber via an inlet from the bulk source, while upon rotation about its axis the feed cylinder repositions the pins to be horizontal in the ejection position so to be able to be advanced out of the chamber by means of the driver tool. Rotation and positioning of the feed cylinder is produced by a unique indexing arrangement operated by the driver tool ram, including a ratchet wheel drivingly connected to rotate with the feed cylinder.
