Title: Method for treating continuous extended lengths of tubular member interiors
Inventor: AVES WILLIAM L JR
IPC: C23C12/02
Filed: 1995-04-28
Abstract: A chemical vapour deposition method is provided for case hardening a ferrous metal interior tubular surface by exposure to diffusible boron with or without other diffusible elements such as silicon to enhance the wear, abrasion and corrosion resistance of the surface. The pack composition used allows for borosiliconizing of the interior surface without sintering or adhering to itself and/or adhering to the surface. The pack composition comprises between about 5% and about 20% by weight of a suitable source of boron; between about 2% and about 10% by weight of silicon material; between about 2% and about 15% by weight of an activator; and the balance being a non-sintering, non-adhering filler. The pack composition is substantially free of diffusible carbon thereby minimizing carburization of the interior surface of the tubular member, and remains free-flowing after the heating and cooling steps, to permit the treatment of continuous lengths of the interior surface of the tubular member whereby the pack composition flows freely from the tubular member interior after the treatment.

Abstract: A rotating electrical machine has openings (105) in its stator teeth (101) occupying a substantial part of the surface area of each tooth so that the stator windings (103) have only a short thermal path to axial cooling ducts created by the openings. In another embodiment, each rotor tooth (109) is provided with a recess (110) at one corner of the tooth to form a recess axial cooling duct; the recess may be of such a depth as to expose part of an adjacent slot (118) to the recess duct. Cooling is by air, either in a single-ended or a double-ended axial ventilation system.
Patent CA-2149839-A1 (CA)
Inventor: FONDA RAYMOND N
IPC: E03D9/08
Filed: 1995-08-08
Abstract: A hand-held bidet apparatus made of hard plastic or metal is provided, which the user attaches by means of a snap-on or threaded connecter to a conduit leading to a tap assembly adjusted to the desired water temperature of the user.  Water released from the tap moves through the conduit to the bidet and stops at a water release valve and button.   Depressing the button releases the water into the mouthpiece of the bidet.  The deep concave shape of the mouthpiece,  which may be circular or oblong, directs the stream of water to the tip of the mouthpiece, which deflects the stream outwards,  at  an angle of approximately 90 degrees with respect to the linear axis of the bidet assembly, so as to contact the user.  The waste water reflects off the user and must exit through the  aperture  in the bottom of the mouthpiece,  thus providing the user with a constant stream of clean water.          The portable snap-on connector of the apparatus permits the user to detach and remove the device, preventing others from using it.  As well, for hygienic purposes, the mouthpiece of the device may be soaked in a container of anti-bacterial cleaning solution which need not be located where the bidet is used.

Patent CA-2157424-A1 (CA)
Inventor: TANAMACHI TOKUNOSUKE
IPC: H02P27/06
Filed: 1995-09-01
Abstract: A control apparatus for controlling an electric vehicle, electric car, rolling stock or electric locomotive, which ensures an inverter output frequency command for its inverter not dependent on the rotor frequency of the induction motor, but controls the inverter output current by a constant current control system, thus preventing an overcurrent, and being capable of accelerating or decelerating the vehicle at a torque precisely corresponding to a current command.  The inverter output frequency command is modified to increment or decrement in accordance with a frequency-to-time rate-of-change command that has been updated by being controlled by the current control system.  Since the inverter output frequency command is basically not dependent on the rotor frequency of the induction motor, and since the output current of the inverter is controlled by the constant current control system, there are the advantages that an overcurrent is not likely to occur, and the vehicle can be accelerated or decelerated at a torque precisely corresponding to the current command.

Abstract: In accordance with the present invention, there are provided nucleic acids encoding human NMDA receptor protein subunits and the proteins encoded thereby. The NMDA receptor subunits of the invention comprise components of NMDA receptors that have cation--selective channels and bind glutamate and NMDA. In one aspect of the invention, the nucleic acids encode NMDAR1 and NMDAR2 subunits of human NMDA receptors. In a preferred embodiment, the invention nucleic acids encode NMDAR1, NMDAR2A, NMDAR2B, NMDAR2C and NMDAR2D subunits of human NMDA receptors. In addition to being useful for the production of NMDA receptor proteins subunit, these nucleic acids are also useful as probes, thus enabling those skilled in the art, without undue experimentation, to identify and isolate related human receptor subunits. Functional glutamate receptors can be assembled, in accordance with the present invention, from a plurality of one type of NMDA receptor subunit protein (homomeric) or from a mixture of two or more types of subunit proteins (heteromeric). In addition to disclosing novel NMDA receptor protein subunits, the present invention also comprises methods for using such receptor subunits to identify and characterize compounds which affect the function of such receptors, e.g., agonists, antagonists, and modulators of glutamate receptor function. The invention also comprises methods for determining whether unknown protein(s) are functional as NMDA receptor subunits.

Title: Optical Modulation Device Having Bias Reset Means
Inventor: NODA ARIHIDE
IPC: G02F1/01
Filed: 1995-11-03
Abstract: An optical modulation device comprises an optical modulator in which the operating point is varied according to a bias voltage.  A phase deviation of an operating point from a selected optimal operating point is detected by a phase comparator based on an output light of the optical modulator.  The bias voltage is generated within a predetermined voltage range by a DC amplifier so as to reduce the phase deviation.  A reset circuit resets the bias voltage at the ground voltage associated with the selected optimal operating point when the optical modulator is powered up and passes the bias voltage to the optical modulator at all other times.

Title: Method and apparatus for determining and indicating network integrity
Inventor: FUJIMOTO KENNETH N
IPC: H04L12/26
Filed: 1995-03-09
Abstract: A method and apparatus are provided for determining and indicating the integrity of a network that interconnects a group of nodes. Each node includes an internal clock (42 or 58), an indicator (27) for emitting a signal at a synchronized signaling interval and a processing unit (36 or 60) electronically coupled to the indicator and the internal clock. The processing of the node causes the indicator to emit a signal at the synchronized signaling interval. When the integrity of the network is intact, the processing unit of each node causes the indicator of the node to emit a signal at the same synchronized signaling interval. As a result, all of the indicators are emitting signals in unison. When the integrity of the network has been lost due to a malfunctioning node or physical break, on a group-to-group basis, the indicators of those nodes improperly communicating with each other emit signals at different synchronized signaling intervals. As a result, the indicators emit signals in an asynchronous manner.

Title: Shear stable lubricating compositions
Inventor: ADAMS DAVID ROBERT
IPC: C10M171/02
Filed: 1995-06-12
Abstract: This invention relates to shear stable lubricating compositions, particularly multigrade oils for crankcase lubrication of gasoline and diesel engines. Multigrade crankcase oils are formulated with an ashless dispersant comprising an oil soluble polymeric hydrocarbon backbone having functional groups in which the hydrocarbon backbone is derived from an ethylene alpha-olefin (EAO) copolymer or alpha-olefin homo- or copolymer having an <o>M</o>n of from 500 to 7000. They provide better fuel economy and better starting at cold temperatures. More economical multigrade crankcase oils may also be blended with less shear stable VMs for improved economy, with a possibility of employing a wider range of polymers. Oils may be blended having extremely good oil shear stability for the most demanding applications where high performance is required such as in turbocharged engines and racing engines, with reduced mechanical breakdown of the oil.
