Patent CA-1314938-C (CA)
Title: Transceiver system for communication over wire laid along the path of guided vehicles
Inventor: HILL LAWRENCE W
IPC: G05D1/02
Filed: 1988-10-31
Granted: 1993-03-23
Abstract: ABSTRACT OF THE DISCLOSURE      The system comprises transceivers employing identical modems, one located at a fixed position and connected to the wire and one on a vehicle guided along the wire.  The trans-ceiver's specialized modems may be connected to a central host which may be a computer, to a programmable controller, or to a communications bus as required.  Additional trans-ceivers may be connected to the communications bus for com-munication between the central host and additional wires. All central host signals are transmitted to all wire con-nected modems and sent out on all wires.  All signals from vehicle modems are transmitted back to the central host. Each transceiver is adapted to employ one or more identical modem,  each connected to a different wire.  Communication between the wire and a vehicle is by means of an inductive coupler employing ferrite rods which is designed such that the transfer function from the fixed modem to the vehicle mounted modem is  substantially identical to the transfer function from the vehicle modem to the fixed modem.  The vehicles may be wired guided vehicles controlled by low frequency signals on the wire.  In this case a special coup-ling circuit is employed so that no modification is required in the equipment normally used to signal along the wire for controlling the vehicle or in the modems connected to the wire.  The modems employ state machines for on-off frequency keying detection, a powerful protocol for error free trans-mission, a specialized circuit that presents different impe-dances during transmission and reception, and a switching circuit for providing high damping on transmission and low damping on reception.

Abstract: Abstract of the Disclosure A solid electrolyte fuel cell capable of operating with a mixture of an oxidizer and a fuel includes a permeable catalytic electrode and an impermeable catalytic electrode separated by an electron insulating, ion conducting, gas permeable solid electrolyte. The device produces charge flow in an external circuit when the permeable electrode is exposed to a mixture including an oxidizer and a fuel such as hydrogen, methane or methanol. The solid electrolyte can be a hydrate aluminum oxide, primarily of the pseudoboehemite structure and either electrode can be Pt or Pd. The solidelectrolyte can be produced by exposing a bulk aluminum surface or a deposited layer of aluminum to water or water vapor or by exposing an anodically oxidized layer of aluminum oxide to water or water vapor. The device is produced in thin film form and can be produced by techniques compatible with thin film device fabrication. The magnitude and direction of the charge flow is dependent on the particular fuel, so that the device can serve as a species selective, gas sensor which does not require the external application of sensing power in order to produce a measurable voltage.

Title: Cathode flow control for fuel cell power plant
Inventor: SCHEFFLER GLENN W
IPC: H01M8/04
Filed: 1989-04-28
Granted: 1992-11-17
Abstract: Abstract Cathode Flow Control For Fuel Cell Power Plant A system and method for regulating the total oxygen content entering the cathode side of a fuel cell stack at less than full power depends on measurement of:  oxygen partial pressure in the cathode exhaust stream; total oxygen entering the cathode; and current produced by the stack.          During partial power operation of the stack, it is desirable to limit the cathode potential, or voltage, by recycling cathode exhaust and mixing it with incoming fresh air fed into the cathodes.          This system ensures that the total oxygen flow to the cathodes remains constant at any given current by reducing the amount of fresh air flowing to the cathodes as the recycled cathode exhaust flow is increased.

The first end of the flexible exten-sion shaft and the chuck have complementarily shaped non-circular cross-sections.  The chuck has an axis and is adapted to receive the first end of the flexible shaft by means of axial insertion of the shaft into the chuck with the non-circular cross-sections in rotationally aligned relationship and the chuck is also adapted to hold the first end of the flexible extension shaft for rotary driven motion of the shaft.  The second end of the flexible extension shaft and the tool have complementarily shaped non-circular cross-sections.  The screwdriver is operable to drive the tool by reason of the second and of the flexible shaft hold-ing the tool for rotary driven motion thereof.  With this arrangement, the flexible extension shaft normally is dis-posed so as to be substantially entirely coaxial with the chuck but is universally deflectable relative to the axis of the chuck so as to position the second end of the shaft and the tool at an acute angle relative thereto.
