Inventor: JOLLY COLIN KENNETH
IPC: E04B1/61
Filed: 1997-01-22
Abstract: Panel members each have a panel body which is disposed between a pair of planar facing members. The panel members are secured together edge-to-edge by means of first and second channel members each of which has a pair of arms joined by means of a web. The arms of each channel member engage in troughs formed along the edges of the facing members of each of two adjacent panel members. The assembly is secured by fastening means which extend between the panel members to fasten together the channel members. The resulting joint is rigid and fire-resistant and provides maximum thermal resistance.

Title: Device for abating carbon monoxide in airbags
Inventor: ITTEL STEVEN DALE
IPC: B60R21/26
Filed: 1995-09-28
Abstract: The present invention provides improvements in a device and in a process for reducing the amounts of carbon monoxide and any oxides of nitrogen in an airbag inflated by a pyrotechnic inflator by exposing the combustion gases released by the explosion of the inflator, wherein carbon monoxide has been to a large extent oxidized to carbon dioxide with a first oxidizing agent, to a catalytic activation system of a supported palladium(II) salt in contact with a thermally stable second oxidizing agent, preferably an organic heteropolyanion capable of donating oxygen. In the device, the oxidant and the catalyst are protected by a thin, impermeable sheet from contact with surrounding atmosphere to prevent progressive deactivation prior to use.

Title: Telephone line interface circuit with voltage control
Inventor: ROSCH REINHARD W
IPC: H04M7/00
Filed: 1993-03-17
Abstract: A telephone line interface circuit comprises two unity gain d.c. amplifiers (132, 134) having outputs d.c. coupled via feed resistors to the line wires. Currents in the feed resistors are monitored via a digital control circuit (152), which can be programmed to provide desired operating conditions. The control circuit controls, via D-A converters (158, 160), currents passed by current sources (142, 148) through resistors (140, 146) at inputs of the d.c. amplifiers, thereby determining voltages at the amplifier inputs and hence on the line wires. These d.c. voltages are smoothed by capacitors (136, 138) used for coupling an a.c. signal to the d.c. amplifiers. The voltage control facilitates adaptive adjustment of the line interface circuit to the line in dependence upon the monitored currents.

Un faisceau de laser à grande puissance (20) est amené sur un point de concentration situé juste au-dessus de la surface de l'écorce (28) de la bille de bois (26). Un jet d'air comprimé est insufflé dans le même axe que le faisceau pour faciliter la formation par celui-ci d'une encoche étroite à la surface de l'écorce. L'avancement et la rotation des billes sont assurés par une pluralité de tarières parallèles (42) qui s'étendent au-dessus de la base d'une auge (40). Les lasers sont placés dans un espace qui se trouve au-dessous des séries de tarières et entre elles. Le point de concentration du faisceau est réglable par rapport à la surface de l'écorce. Le mouvement de la bille par rapport à une tête de laser permet d'obtenir à la surface de la bille une coupure en spirale qui tranche les fibres longues de l'écorce.

Title: A method for making heteromultimeric polypeptides
Inventor: PRESTA LEONARD G
IPC: C07K16/28
Filed: 1996-02-05
Abstract: The invention relates to a method of preparing heteromultimeric polypeptides such as bispecific antibodies, bispecific immunoadhesins and antibody-immunoadhesin chimeras. The invention also relates to the heteromultimers prepared using the method. Generally, the method involves introducing a protuberance at the interface of a first polypeptide and a corresponding cavity in the interface of a second polypeptide, such that the protuberance can be positioned in the cavity so as to promote heteromultimer formation and hinder homomultimer formation.  "Protuberances" are constructed by replacing small amino acid side chains from the interface of the first polypeptide with larger side chains (e.g. tyrosine or tryptophan). Compensatory "cavities" of identical or similar size to the protuberances are created in the interface of the second polypetide by replacing large amino acid side chains with smaller ones (e.g. alanine or threonine). The protuberance and cavity can be made by synthetic means such as altering the nucleic acid encoding the polypeptides or by peptide synthesis.

Patent CA-2215085-A1 (CA)
Title: Flow signal filter
Inventor: DIMSA ROBERT
IPC: B60T13/66
Filed: 1997-09-10
Abstract: Method and apparatus for providing a filtered signal which indicates of a flow of fluid to a fluid pressure communication conduit, the flow being dependent upon the pressure of fluid in a chamber. The pressure in the chamber is controlled by one or more pressure adjusting valves. The invention provides for receiving into a data processing module one or more valve signals indicating open states of the pressure adjusting valve or valves and also a flowrate signal from a flowrate sensor, which represents the real instantaneous flowrate, and it is this signal which needs to be filtered to remove transients.      The invention provides for choosing between a first processing mode and a second processing mode for the flowrate signal. The first processing mode is used when the second processing mode is not in effect and when neither of the valve signals indicates an open valve. The second processing mode is activated when a valve signal indicates an open valve. The second processing mode, when activated, proceeds according to a predetermined procedure and then returns to the first processing mode after no valve signal indicates an open valve.      The signal is processed by either the first processing mode or the second processing mode, depending on whether valve signals have been received, and provides the filtered signal as an output to equipment external to the data processing module.

Title: High voltage power supply having multiple high voltage generators
Inventor: KRICHTAFOVITCH IGOR A
IPC: H05G1/32
Filed: 1996-04-05
Abstract: A high voltage power supply (40) having a plurality of high voltage generators (50a, 50b,... 50j) that produce a controlled current in a load (24) having a capacitive component. Each high voltage generator consists of a pulsewidth-modulated (PWM) inverter, a high voltage transformer, and a high voltage full bridge rectifier. The high voltage generators are divided into three groups:  Group I, Group II, and Group III. During a driving mode of power supply operation, the Group I, Group II, and Group III high voltage generators produce an output voltage (Vgen) from the power supply which exceeds a voltage (Vc) across the capacitive component of the load, causing the current in the load to increase. When the current in the load reaches a desired value, the power supply enters a tracking mode of operation. During the tracking mode, the Group I and Group II high voltage generators produce an output voltage (Vgen) from the power supply which equals the voltage (Vc) across the capacitive component of the load. The current through the load remains constant while the power supply tracks the voltage across the capacitive component of the load. The driving mode and the tracking mode are repeatedly performed, as the high voltage generators are driven by a square wave voltage (Vsw) produced by a timing generator (66). A control circuit (56) is also provided in the power supply to enable or disable additional Group II high voltage generators in response to fluctuations in an input voltage and the voltage across the load.

Abstract: An adjustable hanger assembly is disclosed for mounting and supporting an electrical box between a pair of structural supports, such as studs or joists.  The adjustable hanger assembly is designed to properly position electrical boxes of different depths between the structural supports such that the open end of the electrical box is flush with the exterior surface of the wallboard or plasterboard, e.g., dry wall or sheet rock. The adjustable hanger assembly has a pair of telescoping support members slidably coupled together and a hanger strap fixedly coupled to an electrical box.  The support members are preferably tubular with a rectangular transverse cross-section.  One side of the support members acts as a positioning edge for maintaining the open end of an electrical box of a first depth flush with the exterior surface of the wall board.  Each of the support members has a pair of positioning flanges with their free ends acting as positioning edges and a third side with no flange acting as a positioning edge for selectively maintaining the open ends of three different depths of electrical boxes flush with the exterior surface of the plasterboard, depending on which of the positioning flanges are used.
