Patent CA-2138159-A1 (CA)
Title: Method and device for the protection of people or objects
Inventor: KUEHNERT EDUARD
IPC: G08B13/22
Filed: 1993-06-16
Abstract: The invention concerns a method and device for protecting people or objects, an alarm signal being triggered when people or objects are approached or taken away without authorization. The aim of the invention is to provide a simple method of ensuring discrete, reliable protection for people or objects, while allowing the people or objects unrestricted mobility. To achieve this, the invention calls for an emitter (14) to emit a signal which prevents the alarm signal from being triggered until the distance between the emitter (14) and receiver (2) exceeds or falls below a pre-determined value or the transmission path between the emitter (14) and receiver (2) is interrupted. It is also possible to generate a range signal which is representative of the distance between two protection elements and which produces a variation in the pitch or loudness of the alarm signal, the variation depending on the magnitude of the range signal.

IPC: H02K3/24
Filed: 1994-12-22
Abstract: An improved rotor end winding assembly for an electrodynamic apparatus includes a stack of conductive straps that are configured to turn about an end turn portion of a rotor and include a top strap, a bottom strap and a number of intermediate straps that are stacked between the top strap and the bottom strap. A space defined between the rotor shaft and the bottom strap is divided into a high pressure zone and a low pressure zone by a zone block. A stepped coolant passage defined in the stack includes an ascending passage that leads from the high pressure zone toward the top strap and in the direction of the zone block and low pressure zone, and a descending passage that leads from the ascending passage to the low pressure zone. As a result, coolant will flow from the high pressure zone to said low pressure zone to efficiently cool said stack of straps.

Patent CA-2142374-A1 (CA)
Inventor: JONES PETER D
IPC: F15B21/044
Filed: 1995-02-13
Abstract: A  self-bleeding  multi-stage  or  single-stage hydraulic    cylinder    system    is    disclosed   which automatically  bleeds  entrapped  air  from  within  the cylinder each time the cylinder is cycled.   The self-bleeding structure preferably includes a fixed elongated tube mounted to the base plate of the cylinder,  and an axially moveable elongated tube telescopically mounted on the fixed tube.  A biasing compression spring forces the moveable tube upward to a predetermined extent when the cylinder is extended.  Upon contraction of the cylinder, air trapped therein is purged or bled from the cylinder through the top end of the axially moveable elongated tube  into  a  fluid reservoir.   In the  final  stage  of contraction of the cylinder,  hydraulic fluid is  forced through the fixed and moveable elongated tubes thereby forcing  the  remaining  air  trapped therein out  of  the cylinder and into the hydraulic fluid reservoir.
Patent CA-2142774-A1 (CA)
Title: Touch screen having reduced sensitivity to spurious selections
Inventor: CASEBOLT MARK
IPC: G06F3/042
Filed: 1995-02-17
Abstract: A touch screen assembly including a molded cover and base is described.  A mounting board is sandwiched between the cover  and  the  base  and  supports  a plurality of  LEDs  and detectors.   Cylindrical guides corresponding to each of the LEDs and detectors are formed in the base when the base and cover  are  attached.    The  guides  at  the  LEDs  limit  beam spreading and guides at the detectors prevent off-axis light from being detected.   Support pedestals formed in the base, together with the cylindrical guides help align and support the LEDs and detectors to prevent misalignment and problems associated with fatigue.  The cover is attached to the base by catch hooks which may be reached without disassembly of the CRT.  Access to the mounting board is thereby facilitated.

Inventor: CUNKELMAN BRIAN
IPC: B60T13/66
Filed: 1995-03-23
Abstract: A microprocessor based electro-pneumatic brake control system for a railway train including both an automatic brake control system and an independent brake control system in which the independent brake control system includes an application electro-pneumatic valve means to control application of air pressure to locomotive brake cylinders in response to an application brake control signal and a release electro-pneumatic valve means to control release of air pressure from such locomotive brake cylinders in response to a release brake control signal. The application electro-pneumatic valve means is biased to a normally closed position, in the absence of such application brake control signal thereto, to prevent venting of application air pressure from the locomotive brake cylinders in the event of a power failure, while the release electro-pneumatic valve means is biased to a normally open position, in the absence of such release brake control signal thereto, to prevent trapping of air pressure in the locomotive brake cylinders in the event of a power failure. In addition, the release electro-pneumatic valve means is provided with a restricted outlet port to retard exhaust of air from the locomotive brake cylinders in the event of a power failure following a brake application. On brake control systems also having an mu valve to cut-off the independent brake control system in a dead locomotive in a consist, the mu valve is biased to normally be in a closed position to prevent venting of application air pressure via the mu valve in the event of a power failure.

Patent CA-2157492-A1 (CA)
Inventor: COTTER DAVID
IPC: G02F3/00
Filed: 1994-03-01
Abstract: In a method of recognising an optically encoded binary word, the word is chosen from a subset of binary words for which W?T=0 if W=T, W?T=1 if W?T is true, where T is the target word, W is the word to be compared and ? is the operation formula (I). The word is recognised by carrying out in the optical domain a bit-wise Boolean AND operation. The operation is carried out on the word to be recognised and the complement of the target word. The AND operation may be carried out by introducing the word to be recognised and the target word into a nonlinear crystal and detecting the second harmonic output from the crystal. The complement of the target word may be generated by a fixed word-forming network. The method may be applied to recongnising the address of a packet on an optical network.

Title: Electronic interlock for multiple pto enable switches
Inventor: SWENSON ERIC T
IPC: B60K25/00
Filed: 1995-09-29
Abstract: Multiple control-request switches are operatively coupled by an electronic interlock circuit with an electronic engine control that controls an engine that powers a heavy duty automotive vehicle. The vehicle is also equipped with one or more devices, such as an air-compressor or hydraulic pump, that are powered from the engine via a power take-off. The control-request switches request control of this equipment from various stations via control of an operational function of the engine, such as control of engine speed. The interlock circuit functions to allow only a first-to-be-actuated of the control-request switches to acquire control so that subsequent actuation of any other switch causes the control to go to a default mode to avoid conflicting control of the engine and equipment powered through a power take-off.
