Title: Belt buckle with interlocking dual tongue and floating peg
Inventor: ANTHONY JAMES R
IPC: A44B11/25
Filed: 1992-01-03
Abstract: A seat belt buckle with a pair of buckle tongues. The buckle includes a spring mechanism movable within the buckle housing from a position blocking engagement of a latch when a single tongue is inserted to a position away from the latch when both tongues are inserted allowing the latch to engage the tongues. In one embodiment, a latch indicator is slidably mounted to the buckle push button in the buckle cover and includes a lower end contacting the latch. The indicator is movable from a position flush with the buckle push button when the latch is not engaged with the tongues to an upraised position over the button when the latch moves up and engages the tongues. The tongues have mating portions, but are separable.

Title: Peak and trough detection circuit
Inventor: GROVES DAVID H
IPC: G01R19/04
Filed: 1992-02-14
Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides for a peak or trough detection circuit and a method utilizing the circuit to detect peaks and troughs of a varying amplitude waveform signal.  The circuit comprises means for receiving a varying amplitude input signal, means for producing a floating reference signal a predetermined voltage difference lower in amplitude relative to each peak or trough, and comparator means for determining when the input signal is equal to the reference signal and thereafter producing a signal indicating a peak or trough has been detected.  The method comprises generating a floating reference signal a set voltage drop lower in amplitude relative to each peak or trough of the input signal, comparing the input signal with the reference signal, determining when the input signal is equal to the reference signal and producing a signal indicating a peak or trough has been detected when the input signal is equal to the reference signal.  The circuit and method are useful in decoders for decoding data information contained in a varying amplitude analog waveform signal.

Patent CA-2062870-A1 (CA)
Inventor: LEE MICHAEL C G
IPC: H04M19/08
Filed: 1992-03-12
Abstract: An interface unit for interconnecting a telephone central switch to a personal computer.  The interface unit receives power and data from the switch over a two wire twisted pair.  The data is in a half duplex TCM (time compression multiplexed) format and is transformed into standard digital data with the logic "1" and "0" being represented by +5V and 0V respectively.  The standard digital data is then arranged into 8 bit words and encoded in either an asynchronous or synchronous manner depending on the type of computer.  The interface unit has a line interface circuit which provides the physical interface between the interface unit and the computer.  The interface unit has a transmitter circuit which converts the +5V and 0V digital signals to -5V and +5V, respectively.  These values are recognised by the computer as logic "1" and "0".  The interface unit also has a receive circuit which takes the computer output signals (between -5 and -12V for logic "1" and between +5 and +12V for logic "0") and converts them back into standard digital format.

Title: Human esophageal epithelial cell lines
Inventor: STONER GARY D
IPC: C12Q1/02
Filed: 1990-09-27
Abstract: Human esophageal epithelial cells having replicative capacity in cell culture that is enhanced compared to normal cells and are unable to produce tumors is disclosed. Normal human esophagus tissue from two autopsy specimens was explanted in serum-free medium.  Epithelial outgrowths were subscultured, then transfected by strontium phosphate coprecipitation with plasmid pRSV-T consisting of the RSV-LTR promoter and the SV40 large T-antigen gene. The transfected cells formed multilayered colonies within 3-4 weeks, which were transferred and developed into cell strains (HE-451 and HE-457). Both strains grew exponentially for 8-10 weeks, then senesced. After a ''crisis'' of 6-8 months, isolated colonies developed into two lines, HET-1A from HE-457 and HET-2A from HE-451.  These have now undergone 143 and 122 population doublings, respectively. Both have epithelial morphology, stain for cytokeratin and the SV40 T-antigen by immunofluorescence, and have remained nontumorigenic in athymic mice for 12 months. The immortalized esophageal lines in serum-free system are useful for investigating the action of putative esophageal carcinogens.

Filed: 1992-08-26
Abstract: Vinyl C1 to C3 alkanoate/C2 to C4 alkylene copolymer emulsions eg vinyl acetate/ethylene, are usable as wet adhesives and pressure sensitive adhesives for a number of applications. Their bonding to the surfaces of lower polarity, eg polyethylene, is improved by including vinyl esters of C4 to C18 primary or secondary carboxylic acids as a monomer. As the results presented in Table I indicate, a particularly preferred balance of properties, especially increased adhesion to hydrophobic substrates with little or no reduction in cohesive strength, is achieved by the use of the 2-ethyl hexanoate monomer, in accordance with a preferred embodiment of the invention.

Title: Thermoplastic multilayer composites
Inventor: MUEGGE JOACHIM
IPC: B32B27/08
Filed: 1992-11-10
Abstract: A novel thermoplastic multilayer composite comprising a layer of a moulding composition based on a polyamide and intimately bonded to a layer of a moulding composition based on a mixture of 95 to 60% by weight of a linear, crystalline polyester and 5 to 40% by weight of a polymer containing reactive groups other than epoxy groups. At least 50% of the end groups of the polyamide are amino end groups. The multilayer composite according to the invention have a good mechanical resistance and a good barrier action against diffusion of chemical agents, sol-vents and fuels. Since the two layers are intimately bonded one to another, no shearing or delamination of the layers occur during thermal expansion or bending. The multilayer composites according to the invention may be used for manufacturing of con-struction components, in electrical, mechanical and car industries or as foodstuffs packaging films.
Patent CA-2083086-A1 (CA)
Title: Air-blower/vacuum attachment
Inventor: ASHLEY PHILIP
IPC: A45D24/32
Filed: 1992-11-17
Abstract: ABSTRACT OF THE DISCLOSURE        A device for styling wet hair that simultaneously attaches to a hand-held blow dryer and a vacuum source, such that hot air from the blow dryer exits the structure in close proximity to suction produced by the vacuum source.  The attachment has a first chamber, one end of which is coupled to the blow dryer, and a second chamber, one end of which is coupled to a vacuum source.  The opposite end of the first chamber has a shield mounted on it from which several shafts protrude.  Each shaft has a longitudinal slit for the exit of hot air, and the group of shafts may be used as a comb for styling hair.  The opposite end of the second chamber directs suction during drying and styling.  The suction draws the hot air along the scalp, thus lifting the hair and giving it the appearance of volume.  A desired hair style is created without requiring positioning of the hair by the user's fingers, combs, brushes, etc.  The suction reduces the risk of the scalp and the user's fingers becoming overheated by the hot air.

Title: Field effect transistor
Inventor: SHIGA NOBUO
IPC: H01L29/10
Filed: 1994-08-02
Abstract: ABSTRACT OF THE DISCLOSURE     A field effect transistor of the present invention includes a semiconductor substrate, an active layer formed by doping an impurity in a surface region of the semiconductor substrate, two heavily doped layers formed respectively by doping the impurity at the two end portions of the active layer, a gate electrode formed on the active layer to be in Schottky contact with the active layer, and source and drain electrodes formed respectively on the two heavily doped layers to be in ohmic contact with the two heavily doped layers.  The length WC of a portion where a gate-electrode-side portion of at least one of said source and drain electrodes and said heavily doped layer overlap each other is set with respect to a length WG of a portion where at least one of source- and drain-electrode-side edge portions of said gate electrode and said active layer overlap each other to satisfy 1[µm] + WG < WC < 5WG. For this reason, a drain current flowing in the gate-electrode-side edge portion of the source or drain electrode is distributed as compared to the prior art, thereby reducing the contact resistance of the source or drain electrode.  Therefore, since the drain-source resistance in an ON state is reduced, the field effect transistor can he applied to a circuit which requires a high breakdown voltage as needed.
