Abstract: UNIVERSAL ELECTRICAL CONNECTOR FOR RECEIVING  DC AND AC ELECTRICAL CONNECTORS            Abstract of the Disclosure A universal AC/DC electrical connector for selectively coupling either a mating direct electrical current (DC) electrical connector or a mating alternating electrical current (AC) electrical connector to selectively receive both  direct  electrical  current  (DC) and  alternating electrical current  (AC)  therein.   The AC/DC electrical connector has a pair of direct current contacts, a pair of alternating current contacts, and a ground contact.  When DC electrical connector is coupled to the AC/DC electrical connector,  the direct current contacts and the ground contact  electrically  engage  corresponding  electrical contacts  of  the  DC  electrical  connector,  while  the alternating  current  contacts  of  the  AC/DC  electrical connector  remains  uncoupled,  i.e.,  alternating current connects  of  the  AC/DC  electrical  connector  does  not electrically engage the contacts of the DC electrical connector.  When AC electrical connector is coupled to the AC/DC  electrical  connector,  the  alternating  current contacts and the ground contacts of the AC/DC electrical connector engage corresponding electrical contacts of the AC electrical connector.  The AC/DC electrical connector can also be provided with a sensor in the form of a pilot contact or reed switches for determining whether direct electrical current or alternating electrical current is being supplied thereto.

Title: Device for coating solid particles
Inventor: KOENIG AXEL
IPC: B01F25/74
Filed: 1994-10-05
Abstract: The device proposed has an annular gap, located between two parts (5a, 5b) of a disc, to allow melt veil to escape. The invention proposes that both pans of the disc are connected to each other by a central, fine thread designed to adjust the size of the gap and that the two parts of the disc can be rotated with respect to each other.

Abstract: An electrically operated hook-type coupler for attachment to an end of a railway transit vehicle for joining adjacent ends of a pair of such railway transit vehicles, in which a gathering core is provided at the forward end of a coupler head, with a hook member pivotally mounted within the gathering core,  and being pivotal between a latch position and an unlatch position for engaging and disengaging a comparable hook member,  and further including a spring to bias the hook member to the latch position.  A driving device is also included within the gathering core for forcibly pivoting the hook member to the unlatch position to uncouple the hook member from any other hook member,  while an electrically operated actuator is provided outside of the gathering core, which in response to appropriate signal, will activate the driving device to disengage the hook member.   A lever arm is also provided to permit manual operation of the driving device to disengage the hook member.  Manual operation does not require any preconditioning of the coupler and automatically resets for electric operation.

Patent CA-2157742-A1 (CA)
Title: Interactive Surveillance Device
Inventor: HART FRANK J
IPC: G08B13/189
Filed: 1995-09-07
Abstract: An automated interactive surveillance device provides passive infrared surveillance of a predetermined area to determine if an intruder enters the area. When the passive infrared detectors detect such an intruder, the device acts to aim a camera and ultrasonic rangefinder in the appropriate direction. The rangefinder determines the precise distance from the device to the intruder, whereupon the camera is accurately focused, the focal length adjusted for a relatively narrow field of view providing good resolution at the selected distance, and the angular elevation of the camera is adjusted appropriately. The passive infrared detectors may cooperate with a program to determine an approximate size for the detected intruder, based upon the amount of heat detected and the range determined by the ultrasonic rangefinder, to thus determine whether or not a human threat exists. The device may be elevated, with programming considering camera height, range to the intruder, and amount of heat detected to determine the approximate height of the intruder and aim the camera accordingly for a high resolution facial shot. One or more devices as needed may be connected to a remote monitoring site.

Patent CA-2167785-A1 (CA)
Inventor: LEWIS THOMAS E
IPC: B41C1/10
Filed: 1996-01-22
Abstract: Apparatus and methods for rapid, efficient production of durable lithographic printing plates by a thermal-transfer process that does not involve ablation.  In response to an imaging pulse, a transfer material reduces in viscosity to a flowable state.  The material exhibits a higher melt adhesion for a plate substrate than for the carrier sheet to which it is initially bound, so that in a flowable state it transfers completely to the substrate.  Following transfer, the carrier sheet, along with untransferred material, is removed from the substrate.

Title: Vacuum-assisted device for mounting an optical moisture sensor on glass
Inventor: TEDER REIN S
IPC: B29C65/00
Filed: 1996-01-11
Abstract: A device (56) to facilitate the mounting of an optical sensor (24) on a windshield glass (18) using a clear adhesive tape is disclosed. The device holds the sensor, with tape exposed, in a vacuum chamber which is sealed against the glass. The chamber is evacuated, and the sensor is then pressed against the glass by the longitudinal movement of a drive shaft (64). The sensor may be installed with consistent force and no trapped air pockets or air bubbles. Air pockets are a special concern because air pockets adversely effect the optical performance of the sensor. The vacuum chamber device may be controlled by a computer, and features a latching mechanism which prevents the sensor from making contact with the glass until the chamber is evacuated.
Patent CA-2187231-A1 (CA)
Title: Coating of substrates
Inventor: GANNON RAYMOND PETER
IPC: H01L21/205
Filed: 1995-04-05
Abstract: A coating is applied to a substrate using an intermediate membrane. The coating is typically conductive or semi-conducting, and the substrate is typically glass. In one form, the coating is applied, in one or more layers, to a flat flexible membrane.  The membrane is then placed on the substrate, and the combination is treated under controlled conditions in a heating chamber.  The combination is first heated in a neutral atmosphere to cause volatisation of the sacrificial membrane, then successively in oxidising and reducing conditions to cause strong bonding between the coating and the substrate. In another form, a non-sacrificial membrane has a substrate contact surface which is physically and chemically compatible with the substrate and which, when treated either chemically or thermally, forms a bond with the substrate.

IPC: B41J2/175
Filed: 1996-12-23
Abstract: An ink-jet bottle and valve system which delivers ink-jet ink to an ink-jet printer apparatus having an ink reservoir. The system has five, main components: (1) a bottle, (2) a housing, (3) a valve, (4), a cover, and (5) a vent tube. Coupled to the ink reservoir, the housing has a nozzle which extends into the ink reservoir and defines a channel through which ink may flow from the bottle to the ink reservoir. The top surface of the housing has a cutout defining a pair of valve rotation stops. The housing also has a bottom surface which includes a lower vent and a lower ink passage each opening to the channel of the nozzle. The valve fits snugly and rotatably within the housing. The internal surface of the valve is threaded to couple the valve to the threaded neck of the bottle. The bottom surface of the valve has an upper vent and an upper ink passage. Finally, a top surface of the valve has a projecting tab. The tab rests in the cutout of the housing and cooperates with the pair of valve rotation stops to limit axial rotation of the valve within the housing between (i) a first position where the tab abuts one valve rotation stop and in which the upper vent and the upper ink passage of the valve align with the lower vent and the lower ink passage, respectively, of the housing, and (ii) a second position where the tab abuts the other valve rotation stop and in which the upper vent and the upper ink passage of the valve are out of alignment with the lower vent and the lower ink passage, respectively, of the housing. The cover engages a flange on the housing and captivates the valve within the housing. Finally, the vent tube allows air, required to equalize the pressure in the bottle, to pass directly to the area atthe top of the bottle above the ink and assure even ink flow.
