Title: Combustion pressure sensor
Inventor: SELLNAU MARK C
IPC: G01L23/10
Filed: 1990-03-27
Abstract: This invention is an annular sensor that measures combustion chamber pressure in an internal combustion engine.  The sensor is located in an engine component opening, such as a spark plug well, and is engaged with first and second walls that define the ends of the opening.  The first wall is located near the combustion chamber and flexes in response to varying combustion chamber pressure.  The second wall is located away from the combustion chamber and remains relatively rigid.  Movement of the first wall relative to the second wall due to varying combustion chamber pressure transmits a load to the sensor.  The sensor generates an output signal that corresponds to that load which may subsequently be used to control engine functions.

Title: Electrofusion marker
Inventor: MINAROVIC JOE T
IPC: B29C65/34
Filed: 1990-04-04
Abstract: F.N. 44019 CAN 4A     Abstract of the Disclosure An electrofusion marker which fuses two pipe sections together and acts as a passive electronic marker.  The electrofusion marker includes a tubular thermoplastic fitting having a coil therein, which is temporarily energized by a power supply.  This heats the  fitting,  causing  it  to  fuse  with  the  pipe sections.   The coil doubles as an inductor,  and a capacitor connected in parallel with the coil creates a resonant LC circuit.  After the pipe sections have been fused together and buried,  the joint may be thereafter  located by emitting a  signal  into the ground, which is picked up by the resonant circuit and re-radiated.   The radiated signal is detected by a receiver,  indicating location of the electrofusion marker and joint.

Title: Method for encapsulating and barrier containment of asbestos fibers in existing building structures
Inventor: RUTLEDGE WILLIAM W SR
IPC: C04B41/52
Filed: 1990-08-08
Abstract: ABSTRACT OF THE DISCLOSURE A method of encapsulating and providing barrier containment for asbestos which forms an integral part of existing building structures includes applying an encapsulating coating comprising a water soluble polyvinyl acetate emulsion to the exterior surface of the structure.  The encapsulating coating is dried to permit maximum penetration and encapsulation prior to performing subsequent steps which may disturb the asbestos fibers in the surface of the building structure.  A primer coating comprising a stronger formulation of polyvinyl acetate emulsion is applied to the structure surface.  An adhesive coating comprising the stronger formulation of the polyvinyl acetate emulsion is applied to the gypsum side of a sheet of a surface covering product that comprises a substantially dry, semi-hydrated gypsum.  The sheet of gypsum product is applied to the surface of the structure by contacting the primer and adhesive coatings with one another.  This procedure is repeated until all of the surface of the structure is covered.  Each subsequent sheet of gypsum product is applied so as to overlap by about two inches the edge of the prior sheet of gypsum product.  A preliminary sealant coating is provided for the exposed surface of the gypsum product and allowed to dry.  A vapor barrier coating comprising a water-based acrylic emulsion is applied to the preliminary sealant coating and allowed to dry.  A final coating comprising the water-based acrylic emulsion is applied over the vapor barrier coating.            A:\FWS4.APP

Abstract: ABSTRACT OF THE DISCLOSURE     A proximity fuzing system includes a passive proximity detection section including an electrostatic probe for detecting initial missile entry into the electric field inherently associated with an airborne target.  Probe signals are processed to determine that the intercepted electric field is characteristic of a valid target, and, if so, an active proximity detection section, such as a radar proximity detector, is rendered operational to trigger a warhead detonator at the optimum point in the missile's engaging trajectory to inflict maximum possible damage on the target.
Patent CA-2025742-A1 (CA)
IPC: H04N1/327
Filed: 1990-09-19
Abstract: A facsimile apparatus of the type which is connected to a digital line and which has the function of automatically informing a particular destination terminal of the reception of a facsimile signal from a distant terminal.  In the apparatus, identification information on a particular facsimile apparatus and a telephone number of a destination terminal are previously stored in a memory unit.  During the reception of a facsimile signal, the apparatus detects an identification information of a distant terminal which is transmitted therefrom over a digital line.  If it is determined that the detected identification information corresponds to the identification information stored in the memory unit, the facsimile apparatus automatically originates a call on the basis of the telephone number of the destination terminal which is stored in the memory unit and sends to the destination terminal a message stating that a facsimile signal has been received from the particular facsimile apparatus.  In another form of facsimile apparatus, a telephone number of a destination terminal is previously stored in the memory unit.  This form of facsimile apparatus is arranged to automatically originates, if a facsimile signal is received over a first channel of the digital line, a call on the basis of the telephone number stored in the memory unit and sends a message stating that a facsimile signal has been received to the destination terminal over a second channel of the digital line.

Patent CA-2030705-A1 (CA)
Inventor: SCHOEN JERRY W
IPC: C23C22/00
Filed: 1990-11-27
Abstract: The thermal flattening of grain oriented silicon steel which is in the semi-processed condition has improved magnetic properties after a stress relief anneal by using a low temperature and high tension flattening anneal. The flattening process is conducted at a temperature between1000 to 1435°F ( 540 to 780°C ) with a tension selected to produce a yield strength / tension ratio from above 5 to about 20 and preferably from 7 to 13. The yield stength of the material will vary depending on the length of the time at peak temperature but are typically from 400 to 4000 psi (29,200 to 292,000 gm/cm2). The material as thermally flattened will have at least about10% stress. After a stress relief anneal above about 1450°F ( 785°C ), the material has significantly improved core loss compared to conventional thermally flattened material. The material is particularly suited for wound transformer core applications.
