Abstract: 63-19,289 METHOD OF PRODUCING MOLDING MEMBERS Abstract of the Disclosure A novel method of producing molding members for automobiles, formed at least partly of a synthetic resin material is disclosed.  According to the method of the invention, synthetic resin material is extrusion molded into a continuous body with a substantially constant cross-section throughout the entire length thereof. A controlled amount of the material is removed from the predetermined location of the continuous body, synchronously with the extrusion molding of the material, such that the cross-section of the continuous body varies in the longitudinal direction of the body. The continuous body subjected to the controlled removal of the material is then cut into the predetermined length of the molding member.

Title: Loop fastening material for fastening device and method of making same
Inventor: NOEL JOHN R
IPC: A44B18/00
Filed: 1988-04-24
Granted: 1993-01-26
Abstract: ABSTRACT       A disposable absorbent article utilizing a fastening device comprising loop fastening material having a backing of orientable material and a multiplicity of fibrous elements extending from the backing.  The fibrous elements are formed by filaments positioned on the backing and secured to the backing when the orientable material of the backing is in its dimensionally unstable state.  The filaments are preferably positioned on the backing parallel to each other and essentially parallel to the path of response of the orientable material.  The filaments are intermittently secured to the backing at spaced, fixed regions along the filaments so that each pair of fixed regions defines therebetween an unsecured catching region.  Thus, the fibrous elements are formed by the shirring of the filaments at the catching regions when the orientable material is caused to be transformed to its dimensionally stable state such that it is caused to contract or gather along its path of response.

Title: Refractory material produced from red mud
Inventor: ALLAIRE CLAUDE
IPC: C04B35/66
Filed: 1988-10-31
Granted: 1993-09-07
Abstract: Abstract:    The invention relates to a process for producing a refractory material and to the material so-produced. The process comprises calcining red mud obtained as a by-product of the Bayer process of producing alumina, grinding the calcined product to form particles of -4 Tyler mesh, mixing the ground product with a binder (e.g. colloidal silica, colloidal alumina, sodium silicate or sodium aluminate) and sufficient water to produce a formable mixture.  The mixture is then formed into a desired shape and fired, preferably after curing and drying.  The resulting fired products have good resistance to high temperatures and to corrosive chemicals such as cryolite.  Consequently, the products can be used as refractory linings for aluminium production cells, and in similar applications.

Abstract: Abstract Ultrasonic surface examination, of interest in a variety of manufacturing and maintenance situations, is facilitated by a method which involves localized sensing of a surface wave by optical-fiber interferometry. The method is particularly applicable for examination of surfaces in confined spaces and wherever line-of-sight examination is difficult. The method is comprised of the steps of providing energy to the surface and sensing a surface wave at least at a point from a portion of the surface under examination. The sensing of the surface wave is accomplished using fiber-opticalinterferometry.

Title: Vector tailgating in computers with vector registers
Inventor: CRAY SEYMOUR R
IPC: G06F17/16
Filed: 1989-05-09
Granted: 1993-08-03
Abstract: VECTOR TAILGATING IN COMPUTERS     WITH VECTOR REGISTERS                 ABSTRACT OF THE DISCLOSURE         Improved performance is obtained in computers of the type having vector registers which communicate with one or more functional units and common memory.  As elements of a vector are read from a vector register for transmission to common memory or as operands to a func-tional unit, the vector register immediately becomes available to receive and store elements of a vector from common memory or a functional unit.  The element-by-element storing takes place simultaneously with the element-by-element reading, and trails the reading by at least one element so as to not overwrite elements yet to be read.  Through the use of this technique a vector register can be loaded with a vector for a subsequent operation without having to wait for the completion of the previous operation which uses the same vector register.

Granted: 1993-03-16
Abstract: ABSTRACT OF THE DISCLOSURE   An inline filter comprises transparent upstream and downstream halves  defining  transparent  hollow right-circular cones  whose flanged lower bases sandwich therebetween a concentric brass fil-ter screen fixedly carried by the flanged lower bases joined to-gether by heat-sealing. The upstream and downstream halves have respective male fittings  for connection  to respective upstream and downstream female couplings of an incoming water supply line for flow of such incoming water through the inline filter. The filter screen, which has an effective filtering capacity, area-wise, of almost thirteen times the area of the internal diameter of the upstream male fitting, filters out and traps sand, dirt, particles and other debris carried by the incoming water. The transparent halves provide visual indication whether the filter screen is clogging up.  Connecting the upstream female coupling to  the downstream male fitting effects backflushing water flow to clean the filter screen.

Abstract: ABSTRACT OF THE DISCLOSURE A system includes one or more databases, a terminal for use by a user and a processor.  The databases store data and retrieve the stored data in response to the receipt of a data retrieval request from the processor.  The terminal generates an input screen and an output screen.  The input screen displays, for the user, data selection criteria identifiers which the user may select to identify data of interest, and functions for processing the data as desired by the user.  The output screen displays the processed data. The processor generates, in response to the selected data selection criteria from said terminal, a data retrieval request for processing by the databases.  Upon receipt of the retrieved data, the processor processes the retrieved data as called for by the selected function selection criteria to generate processed data, which the processor transmits to the terminal for display on the output screen.  In a refinement, the processed data is identified by a data type, and said processor selecting a display type, for example, a line graph, bar graph, or other, based on the data type of the processed data, by which the output screen displays the data.

Abstract: ABSTRACT OF THE DISCLOSURE      A multi-stage entrained liquid-gas separator includes a housing divided into upper and lower chambers.  The lower chamber is provided with a tangential gas-liquid stream inlet into an annular chamber in which the large entrained liquid drops are centrifugally impinged upon the chamber wall and drained into a lower sump.  From the annular inlet chamber the gas-liquid stream is caused to abruptly change direction and flow into a lower-pressure area of the lower chamber for further releasing entrained droplets.  From this area the gas-liquid stream is made to flow into an inner chamber provided within the lower chamber and communicating with the upper chamber.  A preseparator housed in the inner chamber separates by impingement and coalescence liquid droplets still entrained in the gas-liquid stream and drains the coalesced liquid into an inner sump which in turn drains via a trap into the lower sump.  From the preseparator, the gas stream still containing liquid microdroplets is conveyed upwardly into the upper chamber and through a two-stage principal separator in the first, fine upstream stage of which the entrained microdroplets are separated by impingement and coalescence from the gas stream and drained to an upper sump.  In the second, downstream coarser stage of the principal separator, separated liquid droplets emerging from the upstream stage are prevented by impingement and drainage from becoming re-entrained in the gas stream discharged to the atmosphere via a gas outlet.  An embodiment directed to separating oil from gas turbine bearing sump vent air is disclosed.
