Title: Glass-ceramics containing needle-like crystals and method of producing same
Inventor: NAMBU MASATERU
IPC: C03C10/04
Filed: 1989-08-30
Abstract: A glass-ceramics block containing needle-like crystals of at least one compound oxide such as CaSiO3 or Na2Ca3Si6O16 is obtained by mixing a soda-lime glass power with a needle-like crystals precipitation promotor selected from carbonates, hydroxides and nitrates of alkali metals or alkaline earth metals, forming the mixture into a desirably shaped body and heating the shaped body at a temperature not lower than the softening point of the soda-lime glass and not higher than the flow point of the soda-lime glass. The precipitation promotor serves also as a foaming agent. It is also possible to use a powder of a glass containing 10-20 wt% of Li2O as a precipitation promotor for precipitating needle-like crystals of the compound oxide(s) without foaming the glass matrix. In either case the obtained glass-ceramics is high in mechanical strength and thermal shock resistance and useful as a building material.

Title: Obtaining information characterising a person or animal
Inventor: SHERMAN ROBIN LEWIS
IPC: A61B5/117
Filed: 1990-05-09
Abstract: In recognising persons from stored data, a problem arises in deriving data which is characteristic of a person but can be held in a reasonably small store, such as in a credit card, or can be transmitted in a reasonably short time. In the present invention such data is derived by measuring features of similar parts of the body, for example similar areas 21 and 22 on opposite sides of the face, reducing this data statistically and then subtracting corresponding data values. <IMAGE>

Title: Pulse welding apparatus
Inventor: TABATA YOICHIRO
IPC: B23K9/09
Filed: 1990-11-27
Abstract: A pulse welding apparatus such as of arc welding or short-circuiting arc welding that effects the welding utilizing pulse discharge that develops at the tip of a wire electrode, wherein undercut which is a defect in the shape of welding beads develops which deteriorates the welding when the timing for removing the molten mass grown at the tip of the wire electrode is delayed due to a change in the welding condition or disturbance. To eliminate this defect, the pulse current fed to the material to be welded is divided into a plurality of pulse groups, the pulse groups are allowed to have an average current of a maximum peak after a predetermined period of time has passed from the start of the pulse, the pulse current groups are allowed to have a mountain shape in compliance with the removing phenomenon of the molten mass, and pulse period, pulse width and pulse gap of pulse current groups are differed depending upon the wire feed speed or the pulse group period. In the short-circuiting arc welding method, furthermore, the short-circuiting and arcing periods are instantaneously controlled depending on the detected arc length or the wire feed speed to quickly obtain ideal arc length. By so doing, the molten mass can be regularly removed and moved onto the material to be welded. Even in the short-circuiting arc welding, furthermore, variation decreases between the short-circuiting period and the arcing period. Therefore, growth and removal of the molten mass can be controlled independently of the magnetic blow phenomenon of arc, and favorable welding is carried out to improve the quality irrespective of a change in the shape of welding joint and earth point in real arc.

IPC: B01J23/96
Abstract: 906,858. Regeneration of catalysts. ABBOTT LABORATORIES. March 27, 1961 [March 28, 1960], No. 1173/61. Class 1(1) [Also in Group IV(b)] A method of regenerating a rhodium catalyst comprises heating the catalyst at a temperature of at least 100‹C. for at least 1 hour. The catalyst may be in the form of pellets, granules or in its finely divided metallic form or the rhodium may be supported on a carrier such as alumina, carbon, kieselguhr, zirconia,. bentonite, asbestos or silica gel. The rhodium may be mixed with not more than 50% of other noble metals. The method may be used for restoring the activity of a rhodium catalyst poisoned by by-products from the hydrogenation of aromatic compounds (see Group IV(b)). The preferred conditions are 2-24 hours at 200‹-300‹C. In an example a 5% rhodium or alumina catalyst is regenerated by heating in vacuo at 230‹-235‹C. for 3 hours.

Title: Making bi-metallic tubing
Inventor: HARDWICK ROY
IPC: B21C37/15
Filed: 1992-06-15
Abstract: This invention relates to a method for producing bi-metallic tubing wherein a layer (31) of a first metal e.g. steel is metallurgically bonded e.g. by electroplating or fusion welding or explosive bonding to the exterior surface of a core component (29) of a second metal e.g. Ni, Ti, Zr or alloy thereof incompatible for solid state bonding with the first metal by processes other than explosive bonding the resulting cylindrical bonded composite (25) is placed within the bore of a thick-walled tube (33) of a metal e.g. steel compatible for solid state bonding with the first metal and the assembly (39) is heated and expanded by passing it over a profiled mandrel. In passing over the mandrel sufficient pressure is developed at the interface between the bonded composite and the thick-walled tube to form a metallurgical bond at the interface. When the first metal is the same as the metal of the thick-walled tube the interface is eliminated and a bi-metallic tube consisting of a single outer layer of the first metal with a bonded lining of the second metal is produced. <IMAGE>

Title: Deceleration sensing means for a seat belt system
Inventor: FUJIMURA YOSHIICHI
IPC: B60R22/405
Filed: 1993-01-29
Abstract: The deceleration sensing means (7) includes a casing (7a), a lever (7b) having a pawl (7i), and an inertia member (7c) that tilts when deceleration exceeding a predetermined value acts on the vehicle. The bottom of the inertia member (7c) is formed in the shape of a small-mass portion (7j), while the top of the inertia member (7c) is formed in the shape of a large- mass portion (7k), so that the center of gravity of the inertia member (7c) lies at a relatively high position. Further, an actuating projection (7m) is formed on the large-mass portion (7k). Thus, it is possible to obtain a relatively large pivoting stroke of the actuator with a relatively small angle of inclination of the inertia member (7c). The deceleration sensing means (7) can be attached without play by longitudinally press-fitting engagement ridges (7g and 7h) into respective recesses (13j and 13k). By virtue of the wedge effect produced by the slant side surfaces of the engagement ridges (7g and 7h) and the recesses (13j and 13k), the casing (7a) is rigidly attached to guide members. An associated seat belt system is also described in detail. <IMAGE>

Title: Reduced noise interference during handoff
Inventor: DUDCZAK CARY M
IPC: H04W36/38
Filed: 1992-03-02
Abstract: A radiotelephone system reduces noise interference during handoff by muting the audio path of a receiver employed in a target base-station (135). After receiving a handoff request message, a target base-station (135) mutes the target audio path and determines if the target audio path had been enabled by an undesired interfering signal having a common SAT. If the target audio path had been enabled by an interfering signal having a common SAT, the target base-station (135) will use the SAT and the received signal strength indication (RSSI) of the desired transmission of the subscriber (125) to enable the target audio path. Once the SAT and RSSI are present and adequate, the target audio path is enabled, the source audio path is coupled to the target audio path, and the subscriber (125) is handed off from the source base-station (130) to the target base-station (135) without a third party experiencing an objectionable noise blast. <IMAGE>
