Abstract: VECTOR DATA PROCESSING SYSTEM FOR INDIRECT ADDRESS INSTRUCTIONS ABSTRACT OF THE DISCLOSURE A vector data processing system comprising at least an A-access pipeline (27) and a B-access pipeline (28) between a main storage unit (4) and vector registers (21). Associated with the A-access pipeline (27) are a write port (WA) and a read port (RA) selectively connected to the vector registers (21). Associated with the B-access pipeline (28) are a write port (WB) and a read port (RB) selectively connected to the vector registers (21). An additional read port (IA) is linked between the read port (RB) of the B-access pipeline (28) and the address input side of the A-access pipeline (27). When an indirect address load/store instruction is carried out for the A-access pipeline (27), an indirect address is generated from the vector registers (21) via the read port (RB) of the B-access pipeline (28) and the additional read port (IA).

Title: Set association memory system
Inventor: DRUKE MICHAEL B
IPC: G06F12/0864
Filed: 1984-09-25
Granted: 1987-01-06
Abstract: ABSTRACT OF THE DISCLOSURE        A memory system for use in a computer which in the preferred embodiment provides two megabytes of capacity per board (up to four boards) is disclosed.  An ALU generates an address signal which selects a number of set locations in the main memory.  Simultaneously, a portion of the address field is fed to a set association logic circuit for parallel processing.  The set association circuit contains tag storage memories and comparators which store least recently used (LRU) values and compare these LRU values to bit values generated by the comparator.          The set association process updates the stored LRU values and then selects the desired set from the sets addressed in the main memory.  A hash function is also used to provide for dispersal of storage locations to reduce the number of collisions of frequently used addresses.  Because of hardware implementation of hashing and LRU algorithm, a constant predetermined cycle time is realized since all accessing functions occur substantially in parallel.          Several sets of data are accessed similtaneously while a set association process is performed which selects one of the accessed sets, wherein access time is reduced because of the parallel accessing.

Abstract: ABSTRACT OF DISCLOSURE     An electrically powered remotely controlled rearview mirror comprises a pair of mirror-engaging position-adjusting non-rotatable screw shafts, each caused to move longitudinally by a rotatable ball nut received within a spherically socketed annular pinion gear which is rotatably driven by a worm gear on the output shaft of the motor. The ball and socket connection between the ball nut and pinion gear permit the axes of the nut and screw shaft to skew relative to that of the pinion gear. A pair of splines on the interior of the pinion gear engage slots on the spherical surface of the ball nut to establish a driving relationship for simultaneous rotation when the associated motor is actuated.

Abstract: A B S T R A C T     There is described a process for the continuous or semi-continuous fabrication of propellant powders for the production of a powder having reproducable characteristics, in extremely safe conditions, thus overcoming the disadvantages found in the existing batch processes. In accordance with the invention, raw nitrocellulose is homogenised and stored under water in large tanks, from which it is fed in a controlled manner to a continuous centrifuge which re-moves water and alcoholises the nitrocellulose gradually. The alco-holised nitrocellulose is fed continuously to a stage where it is mixed with solvents and additives to form a gel which is compacted and extruded into filaments. Granules are made from the filaments and are transported in small batches to a preliminary drying step which removes that larger part of the solvents, in suitable vessels in a programmed manner. The granules discharged from these vessels are collected, in an inert state, and thereafter the powder is pre-pared and transported hydraulically to subsequent stages, including boiling and final drying.

Abstract: ABSTRACT OF THE DISCLOSURE         A molded, one-piece adaptor for concentrically connecting a steering wheel and a steering wheel column is disclosed.  In particular, the adaptor is useful when the steering wheel column has a tubular form, but the adaptor may be readily modified in order to connect to a steering wheel column having a rod-like form.  The adaptor comprises an upper portion and a lower portion.  The upper portion has a mechanism for meshing with the steering wheel.  The lower portion engages with the steering wheel column.  If the steering wheel column is tubular, the steering wheel column slips over the lower portion which has a plurality of tapered ribs which are spaced around and extend axially along the lower portion.  These  tapered ribs tend to take up any variation in tolerances so as to reduce the rocking between the steering wheel and steering wheel column.

Abstract: ABSTRACT OF THE DISCLOSURE   A cathode ray tube with a fiber optic faceplate is successively stepped to discrete adjoining areas of a photosensitive film upon which a pattern is to be exposed. The pattern is divided into a plurality of sections, which are exposed upon the film by the cathode ray tube one at a time at its successive positions.In each position of the cathode ray tube, its beam traces a pattern of light upon its faceplate that corresponds to one section of the overall pattern. The pattern of light traced on the faceplate is transmitted directly to the film which is incontact with the fiber optic faceplate. As each pattern section is formed on thefaceplate, correction signals are applied to the beam deflection circuits so as to shift all or portions of the pattern formed on the faceplate in a sense to decrease misalignment due to error in position of the cathode ray tube and, moreover, to correct for deviations in the position of the beam trace upon the faceplate caused by static errors that are due to construction of the cathode ray tube.
