Title: Method of forming article with variable composition
Inventor: SAWYER THOMAS FRANCIS
IPC: C23C4/06
Filed: 1991-02-27
Abstract: A method of forming a structure having multiple alloy properties involves spray forming and employs a single alloy system which is subject to modification by addition of modifying elements. The initial part of the structure is made of the alloy (16) by application to the substrate without the modifiers present. The modifiers (32) are added to mix with and dissolve in the alloy in a dispensing crucible (12) supplying the spray forming operation and the coating operation is then continued. The latter portions of the structure have modified alloy content and properties which are modified based on the modification of alloy content. The metal melt may be of a nickel base superalloy and the modifier metal may be aluminium. <IMAGE>

Title: A selectable width, burstable FIFO
Inventor: SCOTT MICHAEL
IPC: G11C7/00
Filed: 1992-08-28
Abstract: A selectable width, burstable FIFO is described. A register memory 530 stores x-bit and y-bit data. Each register of the register memory is y+1 bits wide. Y bits store x-bit and y-bit data and one bit tracks the data width within each register. Burst Ready Logic 575 accepts an m-bit input 43 to select a burst length from 2<m> possible burst lengths. Based on the m-bit input, the Burst Ready Logic outputs a signal indicating when the FIFO is burstable. The empty and full FIFO conditions are determined at 560 using a digital hysteresis. In one embodiment, eight registers store 8-bit and 16-bit data. Each register is 17-bits wide so that 16-bits store 8-bit and 16-bit data. The remaining bit tracks whether the register contains 8-bit or 16-bit data. In this embodiment, the Burst Ready Logic accepts a 2-bit input to select from possible burst lengths of 1, 2, 4 or 8 bytes. <IMAGE>

Title: Delivery valves
Inventor: WARGA JOHANN
IPC: F02M59/46
Filed: 1993-01-29
Abstract: A delivery valve (1) disposed in the delivery line (3) of a fuel-injection pump supplying an internal combustion engine, includes a delivery valve closure member (19) provided with a sealing surface (17) pressed by a compression spring against a valve seat (15) of a body (9). To reduce the pressure waves in the delivery line (3) caused by sudden closure of the delivery valve (11), fuel can back-flow through a throttle (51) and a passage (25) in the member (19) controlled by a non-return valve (41). The non-return valve comprises a valve seat (46), a valve closure member (43), a spring plate (39) and a return spring (37). Fuel flows back unrestrictedly after the non-return valve (41) opens, by the provision of a through-flow channel (53) disposed in, or around, (Fig 2) the spring plate (39). Additionally, a spool (29) installed in the through-flow channel (25) to limit the opening stroke of the non-return valve (41) has a longitudinal bore (33) to provide an unrestricted flow of fuel. A transverse bore (65) issues into the longitudinal bore (33). <IMAGE>

Title: Spill-resistant ventilation of electronic equipment
Inventor: COOPER STEPHEN V
IPC: H05K7/20
Filed: 1994-03-28
Abstract: An enclosure for electronic equipment has a series of vents for ventilating the enclosure while minimizing flow of spilled liquid into the enclosure through the vents. A series of vent pockets is formed in a side wall of the enclosure, extending downward from a top surface 16 of the enclosure so that spilled liquid flows downward into the vent pockets. The vent pockets have a generally u-shaped configuration with an aperture 24 extending through one of the side walls for ventilation. The apertures thus are formed in a plane substantially orthogonal to the top surface and the side wall of the enclosure. A liquid flow path through the vent pocket diverts the spilled liquid away from the aperture, so as to minimize flow of the liquid through the aperture into the enclosure. Another aspect of the invention is a low-cost method of making the enclosure by injection molding (Figure 10). <IMAGE>

Title: Altered antibodies,products and processes relating thereto
Inventor: WINTER GREGORY PAUL
IPC: C07K19/00
Filed: 1993-02-19
Abstract: The present invention relates to altered antibodies which are substantially immuno silent by virtue of their containing selected germ-line amino acid residues which replace one or more corresponding somatically mutated residues in a native antibody. In a process for making a gene for use in preparing such an antibody, one or more somatically mutated amino acid residues in a native antibody are identified as suitable candidate(s) for alteration. A nucleotide coding sequence is made which codes for selected germ-line amino acid residues to replace the one or more somatically mutated amino acid residues. The altered antibody can have variable (V) regions which comprise complementarity determining regions (CDRs) which provide the antibody with capacity to bind a specific antigen; and a selected and predominantly germ-line framework. In processes for making a gene for use in the preparation of such an antibody, there are the steps of (i) obtaining CDR encoding nucleotide sequences which encode CDRs with specificity for the specific antigen and (ii) combining these CDR encoding nucleotide sequences with framework encoding nucleotide sequences which encode the selected germ-line framework. <IMAGE>

Title: pH dependent process for retarding the gelation rate of a polymer gel utilized to reduce permeability in or near a subterranean hydrocarbon-bearing formation
Inventor: SYDANSK ROBERT DUNN
IPC: C09K8/512
Filed: 1994-12-29
Abstract: A process and composition are provided for permeability reduction in a treatment region to improve hydrocarbon recovery from a hydrocarbon-bearing formation. The process includes placement of a crosslinked polymer gel in the treatment region preceded by surface preparation of a gelation solution which is the gel precursor. The gelation solution contains a crosslinkable polymer, a chromium(III)/carboxylate complex crosslinking agent, a carboxylate salt delaying agent and an aqueous solvent. The gel is placed in the treatment region by injecting the gelation solution into a well bore in fluid communication with the treatment region, displacing it into the desired treatment region and gelling the solution to completion forming the permeability-reducing gel in situ. The gelation rate is retarded in a controlled manner by adjusting the composition or concentration, and correspondingly the pH, of the delaying agent in the gelation solution.
