Title: Floating-priority storage control for processors in a multi-processor system
IPC: G06F12/00
Filed: 1978-03-13
Abstract: The disclosure describes a floating-priority storage access control arrangement for plural processors to a shared main storage in a multi-processing (MP) system. The shared main storage logically couples the main storage units provided with each of the processors into a single expanse of real addresses available to each processor. Exclusive access to the shared storage is given to any processor for as long as that processor can provide a burst of one or more successive storage requests. The burst ends when that processor misses a storage cycle by not providing a locally granted request.

Patent ES-474331-A1 (ES)
Title: Controlled flow cooling system for low weight reciprocating engine
IPC: F02F7/00
Filed: 1978-10-18
Abstract: A light metal die-cast head and cast iron block employ a low volume cooling system which cooperates with the differing thermal conductivity properties of said head and block. The cooling concept eliminates the conventional intricate water jacket and replaces it with continuous grooves which wrap hemi-cylindrically about each combustion cylinder in a thinly spaced relation. The grooves are exposed along their length at the deck surface of either the head or block. The total fluid mass in the system is reduced to as little as 1/5. There are two such grooves in the block which (a) extend from one end thereof to the opposite end, (b) are on opposed sides of the cylinder galleys and (c) have substantially no transverse flow in order to promote laminar or controlled flow. There is a critically located straight drilled passage along with two such grooves in the head, the combination of which is restricted in throat area when compared to the throat area of the grooves in the block this results in a high velocity flow in the head and a low velocity flow in the block when they are connected in series flow relation. The straight longitudinally drilled passage (which may include one or more of such passages) is located in the head separating the exhaust and metal valve guides the passage has a throat area equal to or less than the throat area of either of the grooves in the head. Heat extraction is more easily and flexibly programmed to achieve not only a more uniform wall temperature throughout the head and block, but permit a desirably slightly higher average wall temperature than conventional light metal heads for improvement in fuel economy and thermal efficiency.

Patent ES-477642-A1 (ES)
Title: Method of manufacturing socket members for electrical connectors.
IPC: H04Q11/04
Filed: 1979-02-13
Abstract: In a socket member (20) for electrical connectors, the mutually inclined tines (22, 23) are separated by slots (24) which, from the tine root region (24) toward the socket aperture, are limited by parallel edges of the tines (22, 23) over a first partial length, and by divergent edges of the tines (22, 23) over the remaining length. In the method of manufacturing the socket member (20), the mutual inclination of the tines (22, 23) is produced by forming a tube to have a conical taper over a length at least equal to the length (D) of the tines, and then slotting the tube. The starting material is a tube an end portion of which is formed into the conical shape by drawing prior to the slotting operation. Thus, at the roots (19) of the tines at rest, the socket body is not subjected to any stress (tensile deformation on the outside, compressive deformation on the inside), which otherwise would be caused by the subsequent bending operation.

Title: Thyristor circuit for reactive power compensation capacitor - has bidirectional bridge consisting of two antiparallel pair of series thyristors for switching in and out of power network
IPC: H02J3/18
Filed: 1979-03-16
Abstract: The thyristor switching circuit consists of a thyristor bridge with the compensation capacitor (1) in one diagonal and the power network connected to the other diagonal. Each half of the bridge is bidirectional and accordingly comprises two antiparallel pairs of series thyristors. The bridge may be fully or half controlled. In the latter case one pair of series thyristors in each half is replaced by corresponding diodes. The compensating diagonal of the bridge may contain several LC components. The advantage lies in almost entirely eliminating switching losses.
