Patent CA-2057729-A1 (CA)
Title: Method of applying an orthodontic aid, and mould therefor
Inventor: GUIS MARINUS B
IPC: A61C7/28
Filed: 1991-12-16
Abstract: Title:    Method of applying an orthodontic aid, and mould therefor Abstract The invention relates to a method of applying an orthodontic aid to at least one tooth in a row of teeth. A cast of the row of teeth is made by means of moulding and counter-moulding. The aid is temporarily secured to the cast in the desired position. A deformable layer of material is applied to the cast with aid, and this layer is deformed to conform to the shape of the cast with aid and thus a mould is formed. The mould with aid is positioned on the row of teeth and the bonding agent applied for securing the aid is allowed to harden in a controlled manner. Then the mould is removed, and the aid remains behind, secured to the row of teeth by means of the bonding agent. According to the invention prior to placing the mould with the aid on the row of teeth, an adhesive layer is applied to at least a part of the surface of the mould, that is brought into contact with the row of teeth.          This adhesive layer has weaker adhesive strength than the bonding agent for securing the aid to the row of teeth. When the mould is placed on the row of teeth, it is temporarily retained in that position by means of the adhesive layer. The invention further relates to a mould with an adhesive layer for use in this method.

Title: Semiconductor device for improving high-frequency characteristics and avoiding chip cracking
Inventor: KOJIMA MASAKAZU
IPC: H01L23/52
Filed: 1992-01-02
Abstract: A semiconductor device comprises a plurality of gate electrodes, drain electrodes, and source electrodes axi-symmetrically formed on opposite sides of a gate pad and drain pad.  Two source pads are arranged at ends of these electrodes, to which the source electrodes are connected, so that a gate width can be shortened.  Therefore, an output power, gain, etc., can be increased, and the high-frequency characteristics can be improved.  Further, when arranging a plurality of semiconductor devices in parallel, the semiconductor chip can be formed in the shape of a square, i.e., the aspect ratio thereof can be reduced, and therefore, cracks in the semiconductor chip (semiconductor device) can be avoided.

Title: Telephone base member and base support member combinations
Inventor: SCHMIDT JAMES N
IPC: H04M1/11
Filed: 1992-01-22
Abstract: Abstract of the Disclosure A telephone base detachably retains a support by the reception of flanged projections through slots, and then relative sliding movement of the base and support into completely assembled positions.  To dismantle the parts relative sliding movement is required in the opposite direction.  This sliding movement is laterally of the direction of movement required to force the base and support apart.  With the slots and flanged projections formed in rigid structure regions, forcible removal of the base from the support is thus prevented.

Title: Gas turbine group
Inventor: ALTHAUS ROLF
IPC: F23R3/00
Filed: 1992-02-13
Abstract: ABSTRACT OF THE DISCLOSURE      In a gas turbine group essentially comprising a compressor  (1),  a high pressure turbine (3),  a low pressure turbine  (4)  and a generator (5), a pressure wave machine (2) located between the compressor (1) and the high pressure turbine (3) is provided as combustion chamber.  The pressure wave machine (2) includes a cell rotor whose  rotor  cells  form the  actual  combustion volume.  By means of auxiliary devices, the rotor cells are continuously filled with a mixture of compressor air and fuel, which mixture is subsequently ignited. Since the rotor cells filled with the mixture are of fixed volume,  constant volume combustion takes place after ignition.  Because of this fact - that combustion takes place in a closed cell at constant volume   the efficiency of the plant can be significantly increased. Both the delivery of the compressor air  (7)  to the pressure wave  machine  (2)  and the  delivery  of  the driving gases (8, 9) to the respective turbine sections (3, 4) occur directly, without the need to resort to a pipework system.

Abstract: Abstract of the Disclosure There is disclosed a torque transmitting or coupling arrangement for a fastener drive system or the like, wherein the respective externally configured and internally configured components are provided with a series of mating, elliptically curved flutes and lobes. In both the externally and internally configured components, the flutes and lobes are defined by a first series of elliptically curved surfaces which alternate with a second series of elliptically curved surfaces, with the respective surfaces merging smoothly and generally tangentially to define the alternating flutes and lobes on each said component.  One of the components, either the externally configured or the internally configured component will preferably have the flutes and lobes thereon generated from ellipses of substantially equal dimension.  The other component, of necessity, will have the flutes and lobes generated from ellipses of differing dimensions.  It is appreciated of course, that the flutes and lobes on both the internally and externally configured components may be generated from ellipses of unequal dimensions.  In addition, in the preferred embodiment, the centers of the various ellipses which define the flutes and lobes fall at the apexes of regular hexagons.  Also, the centers for both series of ellipses will fall on substantially the same circle.  There is also disclosed the tools which can be employed to form both the external and internal configurations in accordance with the invention.

Title: Shock absorber safety system for workers and method of making same
Inventor: CASEBOLT SCOTT C
IPC: F16F7/00
Filed: 1992-08-24
Abstract: The shock absorber disclosed herein includes an elongate strip of a webbed material or fabric. Both ends of the fabric are cut a short distance along the longitudinal axis of the strip of material, and then one end of the strip is twisted a half turn, or 180°. The two ends of the Webbing are brought together, and the juxtaposed halves of the separate ends may then be folded back on themselves and sewn together to form a loop. One loop may now be fastened as by a safety hook to a worker's safety belt or harness, and the other end fastened as by a double locking snap hook to a rope or cable attached to a fixed structure such as a building or scaffolding. The excess length of webbing may be folded back onto itself until it fits compactly into a housing or casing. The housing or casing must be releasable so as not to interfere with the tearing action of the strip of webbing should the worker fall off the structure to which the shock absorber is attached.

Title: Continuous surface treating method and apparatus with inline centrifugal separator
Inventor: MOTOHASHI TSUTOMU
IPC: F26B5/08
Filed: 1993-06-21
Abstract: ABSTRACT OF THE DISCLOSURE      In a continuous surface treating method and apparatus with an inline centrifugal separator, an object to be treated is contained in a basket and hung from a hanger of an overhead type and a series of surface treatments of the object is carried out by using a continuous conveyer of a power and free type.  By using a hanger attach-detach conveyer, the object is moved from a main conveyer to a sub-conveyer and an excessive treating liquid attached to the object in a previous process is separated by using the centrifugal separator.  Then, the object is returned from the sub-conveyer to the main conveyer to perform a next process.  The surface treating apparatus includes the rotatable basket for containing the object.  When the surface treatment of the object such as a heat exchanger or the like is continuously executed in the conveyer line, a bringing of the excessive treating liquid attached to the object in the previous process into a next process can be prevented and the concentration of the treating liquid in a bath can be maintained to a constant value.  As a result, the obtained film thickness becomes uniform and the quality of the object can be improved.
