Inventor: LEIST ALAN R
IPC: E06B3/48
Filed: 1991-07-29
Abstract: Novel compressible flexible hinge assemblies for connecting abutting panel sections (30 and 50) of upward acting or sectional doors, such as garage doors, are dis-closed. More particularly, abutting panel sections of an upward acting door are hingedly connected together economically and in a weather-tight relationship by a flexible hinge assembly (70) which can be easily installed without the use of tools by snapping it into predesigned elongated slots (61 and 41a) in the abutting panel sec-tions from the rear or interior side of the door. When as-sembled, a compressible flexible hinge assembly (70) of the present invention provides a smooth, flush back sur-face on the rear or interior side of an upward acting door and eliminates the unsightly appearance associated with conventional metal hardware heretofore used to hinge abutting panel sections (30 and 50) of upward acting doors (70).

Title: Dilutable aluminium triformate tanning agents in the form of highly concentrated, storable aqueous solutions and their use
Inventor: ZAUNS-HUBER RUDOLF
IPC: C14C3/04
Filed: 1992-07-06
Abstract: Described is the use of at least substantially storage-stable supersaturated and acidified aqueous solutions of mixtures of aluminium triformate and alkali-metal and/or alkaline-earth formates as a means of supplying a water-dissolved mineral tanning agent based on aluminium formate for the tanning of leather and/or hides using little or no chromium.

Title: Resilient portable floor system
Inventor: NIESE MICHAEL W
IPC: E04F15/18
Filed: 1994-01-28
Abstract: A portable hardwood floor system of interconnected floor sections supported in spaced relation over a substrate includes a plurality of mounts attached to the bottoms of each of the interconnectable sections. Each mount includes a resilient pad to resiliently support the portable floor system above the base and a glide member located below the pad. The glide members are substantially noncompressible under normal floor loading conditions and have a relatively low coefficient of friction with respect to the base. The glide members are slidable on the base to enhance maneuverability in positioning and aligning the interconnectable floor sections, thereby to facilitate interconnection of the sections to form the floor system.      The glide members also protect the portable floor section and/or the base and are also sufficiently durable to withstand frequent handling commonly required of a portable hardwood floor system.

Title: Monolithic mach-zehnder device
Inventor: MILLER WILLIAM J
IPC: G02B5/28
Filed: 1994-02-14
Abstract: Abstract of the Disclosure A monolithic, environmentally stable Mach-Zehnder device is formed by threading first and second dissimilar optical fibers through the bore of a glass tube.  The tube is evacuated and heated to collapse it onto the fibers. The tube is further heated and stretched at two spaced locations to form two couplers that are joined by the two optical fibers.  The fibers have different propagation constants in the region between the two couplers, whereby there is a relative delay in the optical signal propagating in one of the fibers with respect to the optical signal propagating in the other fiber.
Patent CA-2116266-A1 (CA)
Title: Field effect transistor
Inventor: MATSUZAKI KEN-ICHIRO
IPC: H01L29/10
Filed: 1994-02-23
Abstract: ABSTRACT OF THE DISCLOSURE     This invention provides an FET having a high mobility of channel electrons and a high saturation electron rate.  For this purpose, in this invention, an undoped buffer layer, a heavily doped channel layer, and an undoped capping layer are formed on a semi-insulating GaAs semiconductor substrate.  An n+-type drain region and an n+-type source region are formed by selective ion implantation.  Subsequently, a gate electrode, a drain electrode, and a source electrode are formed.  Since the channel layer is formed by gradually increasing the supply quantity of SiH4 gas, an impurity concentration becomes low when the depth from the substrate surface increases.  Therefore, since the impurity concentration becomes low at the bottom of the channel layer along which electrons tend to move, an influence of impurity scattering on carriers can be reduced.

Title: Method and apparatus for implanting synthetic hair
Inventor: AMIRI AHMAD
IPC: A61F2/10
Filed: 1994-04-15
Abstract: Synthetic hair may be implanted using bundles of synthetic fibres joined at their lower end so that they will be firmly anchored in the scalp and not easily pulled out. The implants may be inserted by means of a tool which comprises a short sharp hollow tube and a manipulating handle. The tip of the tube may be inserted into the scalp to provide a conduit into which the synthetic fibres are sewn into the scalp.      The synthetic fibres are implanted by having curved needles at one end and a juncture of several fibres at the other end. The needles are inserted through the tube and into the scalp and out through the outer surface at various locations like normal hair, but because they are joined and anchored within the scalp, will not be easily removed.      Alternatively, the skin can be surgically lifted and the fibre inserted through the skin from underneath.
