Inventor: AVILA JOHN E
IPC: E21B43/116
Filed: 1990-08-30
Abstract: A tubing conveyed perforating apparatus (20) comprising a tubing string (22); a perforating gun (34) suspended from said tubing string; and a primary firing head (32) and a backup firing head (30), both suspended from said tubing string above said perforating gun, and each including a time delay means (130;138) for providing a sufficient time delay between initiation of a firing sequence in the respective firing head and subsequent firing of the perforating gun so that an underbalanced condition may be created in said isolated zone of said well prior to firing of said perforating gun. The firing head preferably includes an actuating piston (72) responsive to a differential between tubing pressure and a sealed low pressure zone (84) contained within the firing head. The actuating piston releases a firing piston (100) which initiates a firing sequence.

Patent EP-0459156-A2 (EP)
Inventor: HEHN WERNER DR
IPC: H01R4/68
Filed: 1991-04-26
Abstract: The invention relates to a superconducting connection of the filaments of an Nb3Sn and an NbTi conductor to a block made of pressed Nb- and Sn-containing powder which has been subjected to a reaction annealing, in which the filaments of the Nb3Sn conductor are embedded and on whose surface the filaments of the NbTi conductor are mounted, and to a method for manufacturing such a connection. The object of the invention is to propose a simple method for manufacturing such a superconducting connection with a current carrying capacity of > 200 A at 3 T and to propose a superconducting connection. According to the invention, the object is achieved in that a pressed-on layer of a deformable metal is connected to the block and the filaments of the NbTi conductor mounted on its surface in such a way that the block, the filaments of the NbTi conductor and the layer of the metal form a firm connection. The essential steps in the method for manufacturing this connection relate to the use of a CuSn foil which is pressed onto the block before the reaction annealing, and the pressing-on of a metal die which enters into a firm connection to the block and the intervening NbTi filament after the reaction annealing.

Title: Data processor capable of simultaneous execution of two instructions
Inventor: HANAWA MAKOTO
IPC: G06F9/00
Filed: 1991-07-15
Abstract: An instruction fetch unit (640) of a data processor (610) capable of simultaneous execution of two instructions fetches a first and a second instruction from a memory (620) in one cycle. The first and the second instruction thus fetched are set in a first and a second register (641, 642) before being decoded in a first and a second instruction decoder (644, 645). Comparators (131, 132) compares data on the destination field of the first instruction with data on the source field of the second instruction. When both the data are inconsistent, a parallel operation control unit (646) permits the first and the second instruction execution unit (651, 652) under the first and the second instruction to execute the two instructions in response to the outputs of the comparators (131, 132). When both the data are consistent, the parallel operation control unit (646) inhibits the parallel execution.

The six clutches and gear wheels in the change- speed transmission part provide 6 forward gears and 3 reverse gears. The 4 clutches and gear wheels in the range-change transmission part provide 4 ranges, giving a total of 24 forward transmission ratios and 12 reverse transmission ratios. <IMAGE>

IPC: H04N1/387
Filed: 1991-09-18
Abstract: For image parts in an image with large circumscribed quadrilaterals, one-dimensional data development is executed where intersection point data on a scanning line are accumulated for plural image parts and one-dimensional raster data of the scanning line is produced based on the intersection point data. For image parts with small circumscribed quadrilaterals, two-dimensional data development is executed where intersection point data in an image part are obtained and two-dimensional raster data of the image part is produced. While the one-dimensional data development requires only a small memory capacity for raster data creation even for relatively large image parts, the two-dimensional data development allows high-speed raster data creation for relatively small image parts.

IPC: G06T7/40
Filed: 1991-09-26
Abstract: A block copy image is divided into several regions R1 and R6, to which different system colors are allocated. A subject region PR including a line break CP1 is specified by an operator. Run-length data of a run-length less than or equal to a predetermined threshold value is automatically detected out of various run-length data representing the subject region PR. White/black designation data defining the color of an image in the run-length data is changed into the color of a linework. The break CP1 in the linework is thus reconnected without operator's instruction. Alternatively, the subject region PR is divided into two portions. The two portions are further divided into separate areas to which different system colors are allocated. This enables an operator to easily detect the position of a line break because the linework elements separated by a break have different colors. The break is then reconnected according to operator's instruction.

Abstract: A mayonnaise-like product is described which is obtainable by processing fresh milk thickened to a paste using particularly amylopectin-rich starch as thickening agent, edible acid, conventional additives and, optionally, edible oil to give an emulsion. By using milk which satisfies the quality requirements for certified milk and starch having a particularly high amylopectin content of normally more than 75 % by weight, a mayonnaise-like product is obtainable, the edible oil or fat content of which can be markedly reduced in comparison with conventional mayonnaise, without impairments occurring with regard to taste, mouth feel and optical impression. The product according to the invention has the desired mayonnaise-like final consistency immediately after production, so that packaging into retail containers or a further processing can be carried out immediately.

Abstract: A computer-generated-image system for a simulator includes a pattern processor (20) in which intensity modulation data stored in tile stores (38) is addressed by inverse perspective transformed coordinates Xe, Ye derived from CRT screen pixel coordinates X s , Y s . Parts of the transformed coordinates Xe, Ye are decoded into address pointers by successive lookup processes at a macro-map store (51) and a tile map store (53). A map number (39) supplied to accompany the display of a polygonal surface selects a respective group of pointers at the macro-map store (51), and corresponding groups of tile numbers at the pattern store (53). Each tile number is used with low significance address bits derived from the Xe, Ye coordinates to provide addresses to individual intensity modulation values in the tile store (38).

Abstract: Spent metal-sulfur compound is regenerated to re-usable metal oxide by moving a bed of spent metal-sulfur compound progressively through a single regeneration vessel having a first (36) and second (38) regeneration stage and a third cooling and purging stage (40). The regeneration is carried out and elemental sulfur is generated in the first stage (36) by introducing a first gas of sulfur dioxide which contains oxygen at a concentration less than the stoichiometric amount required for complete oxidation of the spent metal-sulfur compound. A second gas containing sulfur dioxide and excess oxygen at a concentration sufficient for complete oxidation of the partially spent metal-sulfur compound, is introduced into the second regeneration stage (38). Gaseous sulfur formed in the first regeneration stage (36) is removed prior to introducing the second gas into the second regeneration stage (38). An oxygen-containing gas is introduced into the third cooling and purging stage (46). Except for the gaseous sulfur removed from the first stage, the combined gases derived from the regeneration stages which are generally rich in sulfur dioxide and lean in oxygen, are removed from the regenerator as an off-gas and recycled as the first and second gas into the regenerator Oxygen concentration is controlled by adding air, oxygen-enriched air or pure oxygen to the recycled off-gas by suitable control means.
