Abstract: ABSTRACT                Packaging of electrical components A container for loosely housing dual-in-line components comprises an elongate tubular member.  The tubular member is substantially U-shaped in cross-section and includes a hollow central portion for receiving the body of the components, and flanking portions for receiving the legs of the components.  The tubular member is so shaped that the components can only touch the tubular member in certain predetermined locations and to protect the components from static discharges on contacting the container, only these locations need be made conductive, the remainder of the container being of transparent plastic.  In one embodiment the container may be provided with conducting ribs on the outside so that when two such containers come into contact it is not possible for two non-conducting parts to come into contact so generating static.

Title: Adjustable mirror support
Inventor: SKELTON ALMA T
IPC: A61G5/10
Filed: 1987-02-19
Granted: 1992-01-28
Abstract: Abstract The adjustable mirror support with attached mirror is to be used on a wheelchair or other support to allow a person with limited mobility a view of the people and surroundings behind him.  The adjustable mirror support  is made of a flexible tube with a reinforcing rod inside the tube to make the mirror easily adapted to an individual's needs by bending the arm in any position necessary, the reinforcing rod serving to keep the arm in place in spite of vibrations caused by motion.  It also makes the storage of the mirror possible while leaving it attached to the wheelchair.          The reinforced tubular arm, with special adaptors at the top can be used to hold a camera or a computer keyboard.

Patent CA-1302060-C (CA)
Inventor: CORBIN NORMAND D
IPC: C04B35/80
Filed: 1987-07-20
Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE       Tough composites of polymer derived silicon car-bide fibers in silicon nitride matrices, especially re-action bonded silicon nitride matrices, can be made by precoating the fibers with pyrolytic carbon and con-trolling the nitridation or other process which forms the silicon nitride matrix so that a thickness of at least 5 nanometers of carbon remains in the composite after it is formed.  Failure of such composites is non-catastrophic.  Alternatively, with at least some spe-cific types of polymer derived silicon carbide fibers, composites with non-catastrophic failure can he made by controlling the nitriding conditions to produce an es-sentially void space around the fibers in the final composites.    As still another alternative, the space around the fibers may be partially filled with silicon nitride whiskers generated during the nitridation pro-cess.

Title: Fluidized vacuum seal
Inventor: KORB JEAN G
IPC: B29C48/305
Filed: 1987-09-17
Granted: 1992-03-17
Abstract: ABSTRACT        A sealing mechanism for passing a continuously formed board (10) from subatmospheric pressure to atmospheric pressure comprising lower and upper continuous belts (20, 40), sealing the major faces of the board and means for sealing the minor faces of the board.  The belts and minor face sealing means are covered on the atmospheric pressure side by liquid in a reservoir (18) open to atmospheric pressure.  Liquid seepage through the sealing arrangement is removed from the subatmospheric side.  The minor face sealing means can comprise cams or an inflatable rotor engaging the minor faces.   32,759-F

Title: Solid state reference electrode
Inventor: HEIDER JOHN E
IPC: G01N27/30
Filed: 1987-11-12
Granted: 1991-07-02
Abstract: Abstract A solid state reference electrode comprising a metal/metal salt electrode, an immobilized electrolyte in contact with the metal salt, and a perfluorocarbon copolymer coating on the immobilized electrolyte to prevent migration of the electrolyte away from the electrode.
Patent CA-1307507-C (CA)
Inventor: PEDIGREW COLIN
IPC: B31B50/62
Filed: 1988-01-15
Granted: 1992-09-15
Abstract: The invention relates to a high-integrity closure, sift-proof carton, a method and an adhesive dispensing means for producing same. Foamed hot melt adhesive is dispensed in parallel strips from dispensing guns onto the flaps of the carton, which are thereafter folded down to close the carton. The strips can be spaced so that a continuous tight adhesive seal is formed, especially by providing a strip pattern interdigitating when the flaps contact each other. Since all strips are provided in parallel, while the carton is moved with respect to the dispensing means, application of adhesive is fast and reliable.
