Patent CA-2109439-A1 (CA)
Title: Corrosion-resistant electric cable
Inventor: ZIEMEK GERHARD
IPC: H01B7/29
Filed: 1993-10-28
Abstract: ABSTRACT         In known cables, the cable core is surrounded by a metal inner layer of a sheath and the inner layer is enclosed by a corrugated metal outer layer of the sheath.  These cables do not provide a high level of resistance to corrosion and changes in temperature while providing good shielding of the electrical conductors, without the danger of contact corrosion between the two layers.  In contrast to this, the present invention provides a cable with a common plastic sheath that surrounds electrical conductors that lie against the plastic sheath, an inner layer that is of copper, and an outer layer of the sheath that is formed from a stainless steel, and with an insulating layer that is provided between the inner layer and the outer layer.  This has the advantage that it ensures good resistance to corrosion and temperature changes, permits particularly effective shielding of the electrical conductors and, in addition, prevents contact corrosion between the two layers of the sheath.  The proposed cable is particularly suit-able for use as power and control cables in ships.

Title: Apparatus and Method for Monitoring Contact Pressure
Inventor: RINCOE RICHARD G
IPC: A61F2/50
Filed: 1992-05-21
Abstract: An apparatus (10) and method for monitoring pressure between the surface of a body part and a contact surface employ a plurality of pressure sensors (20) disposed in a matrix array between the contact surface and the body part. The sensors (20) produce analog force signals proportional to pressure, and a monitor receives the analog signals. A computer processor receives the output signals from the monitor to create a force profile for the sensor array. This monitoring apparatus (10) and method is used, for example, to fit prothetics, to monitor bed-ridden and wheelchair-bound patients, to reduce pain and sores caused by uneven distribution of pressure and to monitor pressure between a cast (90) and a person. The sensors (20) may be mounted on a single sheet (22) or on strips for positioning along the body, and monitoring is accomplished by multiplexing and digitizing the analog force signals.

Inventor: NISHIO MAKOTO
IPC: H04B10/272
Filed: 1994-06-08
Abstract: An optical wavelength selection control system in an optical network includes an optical center node device and a plurality of terminal devices each comprised of a work station and an interface.  The optical center node device includes a control circuit, a plurality of optical switches and a plurality of tunable wavelength filters.          When there occurs a collision among the plurality of terminal devices wherein a plurality of terminal devices send simultaneously optical packets to the same terminal device, the control circuit operates to control the optical switches and the tunable wavelength filters such that they select only one optical packet, based on information relating to, for example, a data length to be transferred.          The control circuit sends out an acknowledgement (ACK) signal to the terminal device whose optical packet has been selected.  To each of the terminal devices whose optical packets have not been selected, the control circuit sends out, in addition to a not-acknowledgement (NACK) signal, a signal indicating a resending time schedule.  There is no possibility that these optical packets will be involved in further collisions, which ensures enhanced throughput of the network system.

Title: Halogenated polyaromatic resins as flame retardant additives for polyurethane compositions
Inventor: HAYES JOHN E
IPC: C08L75/00
Filed: 1994-11-29
Abstract: Polyurethane foams having improved flame retardant properties employing small quantities of halogenated polyaromatic resin flame-retardant additive have been discovered. Brominated polystyrene resin is particularly preferred. The additives may be physically suspended in the polyol prior to reaction with a polyisocyanate in the presence of a polyurethane catalyst in a conventional manner to produce improved polyurethane foams. The additives are not chemically bound to other components in the foam, such as the polyol. Because small quantities of dle additives are used, the physical properties of the foams are not adversely affected by their presence.

Patent CA-2147022-A1 (CA)
Title: Position detector with data evaluation circuit
Inventor: MEHNERT WALTER
IPC: G01D3/02
Filed: 1995-04-13
Abstract: A position detector with data evaluation circuit has at least one sensor which, in dependence on movement by which the position to be monitored alters, supplies electrical output signals to a circuit arrangement which produces therefrom a digital signal and puts it into intermediate storage until it is transferred to an evaluation unit. The digital signal reproduces in encoded form the position to be monitored.      An energy converter converts a part of the kinetic energy of the movement into electrical energy and an energy storage means stores the electrical energy and provides same for supply to the circuit arrangement. A monitoring circuit outputs a control signal in response to a threatening drop in the supply voltage below a critical limit value.      When the control signal occurs the digital signal is written into a non-volatile information storage means, in order thereby to make the position detector independent of an external power supply.

Title: An ultrasonic surgical handpiece and an energy initiator to maintain thevibration and linear dynamics
Inventor: OLICHNEY MICHAEL D
IPC: A61B17/22
Filed: 1993-09-17
Abstract: An ultrasonic oscillator drives a tool at a set frequency. An amplitude control runs the oscillator to set the vibration level. A frequency regulator joins the amplitude and the oscillator. A control feedback loop, in the frequency regulator, keeps handpiece linear dynamics. An operational transconductance amplifier, in the oscillator, governs gain of the loop. A circuit connects to the control to retard the rate of current application over time to the amplifier. The circuit has switching to either retard the rate or reset for start up. The amplifier is a current output device with current directly proportional to the bias current and input voltage with bias as gain change for the loop. The circuit limits the bias to the amplifier to modify frequency response and output current. A capacitor delays application of the bias to the amplifier. Replaceable tools of various lengths or shapes positioned along an axis vibrate for surgery at the frequency and a wave length. Tools longer than one wavelength and of configurations tuned to oscillate around the frequency resonate as a function of their material, length and configuration. A flue surrounds the tool and has a hollow elongate semi rigid central body about an axis with a funnel, at one end thereof and a nozzle, at the other to direct annular irrigant/coolant flow therethrough. The funnel and nozzle are resilient. Reinforcing ridges, inside the nozzle, act to maintain concentricity between the flue and nozzle tip and channel irrigant thereabout.
Patent CA-2153387-A1 (CA)
Inventor: KOESTER HUBERT
IPC: C12Q1/6827
Filed: 1994-01-06
Abstract: The invention describes a new method to sequence DNA. The improvements over the existing DNA sequencing technologies are high speed, high throughout, no electrophoresis and gel reading artifacts due to the complete absence of an electrophoretic step, and no costly reagents involving various substitutions with stable isotopes. The invention utilizes the Sanger sequencing strategy and assembles the sequence information by analysis of the nested fragments obtained by base-specific chain termination via their different molecular masses using mass spectrometry, as for example, MALDI or ES mass spectrometry. A further increase in throughpout, can be obtained by introducing mass-modifications in the oligonucleotide primer, chain-terminating nucleoside triphosphates and/or in the chain-elongating nucleoside triphosphates, as well as using integrated tag sequences which allow multiplexing by hybridization of tag specific probes with mass-differentiated molecular weights.
