Abstract: Control device for a buffer memory which distinguishes information items of the "instruction" type and information items of the "data" type, and device with means of replacement (40) which replace the stored information items by current information items according to at least one replacement algorithm. It comprises partitioning means (30) which tend to limit, to a predetermined quantity, a quantity of at least one of the said types of information items. When a current information item has to be loaded, the partitioning means (30) first of all calculate an overall quantity of memory occupied at that moment by information items of the limited type, then compare the overall quantity and the predetermined quantity, . and when the overall quantity is less than or equal to the predetermined quantity, the means of replacement (40) employ a conventional replacement algorithm, . and when the overall quantity is greater than the said predetermined quantity, the means of replacement (40) load the current information item as a priority by replacing a replaceable stored information item of the limited type or in default by replacing a stored information item of the nonlimited type. The value of the said limited quantity is reupdatable. The partitioning means (30) and the means of replacement (40) can be programmed means. Application: computers, microcomputers. <IMAGE>

Abstract: A digital power meter achieves enhanced accuracies through the utilization of a sequence of meter stage improvements. Such improvements include the utilization of a digital phase shift based cycle phase realignment following the scaling function of the meter. The cycle phase corrected signals are digitized utilising a sampling procedure wherein two samples of both current and voltage are taken within a precisely defined sampling interval. These samples are improved by the application thereto of a truncation correction and are averaged prior to being combined to provide quantity signals such as watt, VAR, volt, amperes, and the like. By developing subinterval transfer of components of these quantities to an overflow register, errors otherwise occurring at this stage of metering are substantially eliminated.

Abstract: Un premier élément en alliage de cuivre et un second élément en un autre matériau sont joints en utilisant un insert placé entre les deux et en les soudant par diffusion à chaud avec chaleur et pression. Le matériau de l'insert est un placage de cuivre formé sur la surface de jointure du second élément à souder, de sorte que la conductivité thermique sur les surfaces de jointure entre les deux éléments est améliorée pour effectuer un échauffement par résistance électrique sans à-coups de sorte qu'un travail en continu est possible sans avoir à polir pour enlever l'oxyde de la surface électroconductrice d'une paire d'électrodes. En outre, lorsque le matériau de l'insert interposé entre les surfaces de jointure des deux éléments est un matériau de brasage normal, un nombre pair de corps superposés, chacun consistant en un premier élément, un matériau d'insert et un second élément à joindre, sont superposés l'un sur l'autre de manière que les premiers éléments respectifs sont amenés en contact en bout à bout et sont soumis à un échauffement par résistance électrique. Dans ce cas, le second élément ayant une capacité thermique élevée est mis bout à bout contre la paire d'électrodes de sorte qu'il n'est pas nécessaire d'effectuer un polissage pour enlever l'oxyde des surfaces électroconductrices de la paire d'électrodes, et il est possible de travailler en continu en appliquant le procédé de soudage par diffusion à chaud selon la présente invention.

Abstract: The known king roll reeling machines for shaftless winding of a web of material (4) divided by a lengthwise cut, in particular a web of paper of cardboard, onto sleeves (11) have take-up rollers (6) which are applied during take-up to two king rolls (2, 3) and are supported by guide heads (10) which can be inserted sideways into the sleeves of the two outer take-up rollers (6). The take-up rollers (6) can only be wound with high winding quality up to a maximum diameter. According to the invention, the space delimited by the king rolls (2, 3) and the take-up rollers (6) is sealed and an overpressure is produced in the space. To this end, sealing elements (18) which can be displaced axially to suit webs of different widths and which can be moved simultaneously in an area outside the area of movement of the guide heads (10) and their fastener (carriage (9)) are arranged in the region of the two side ends of the king rolls (2, 3). Frictional engagement between the king rolls is prevented when the sealing elements (15, 18) are in the sealing position.

Inventor: MOLVIG KIM
IPC: G06F17/50
Filed: 1991-07-12
Abstract: Fluid flow is simulated by a massively parallel data processor having combinational logic for processing collision rules at lattice sites. Following collision processing, particle representations are moved to different sites dependent on direction and velocity of the particles. The collision rules are based on collisions of particles positioned at sites of a three-dimensional lattice. Particle representations identify particles of plural energy levels, and the collision rules allow for transfer of energy between particles. Particle representations relate to particles which move along four-dimensional face-centered hypercube lattices which project to the three-dimensional lattice.

Abstract: In order to obtain a standing surface, it is known to bevel off the side transoms of the staircase, this usually being carried out with tools which are not available on site. On the one hand, an exact dimensional specification is consequently necessary, on the other hand this method of construction produces waste material, which unnecessarily makes the product more expensive. The object of the invention is therefore to design a side transom in such a way that it can be produced and assembled by very simple means at reasonable cost. For this purpose, the invention provides that on at least one end face of the side transom (1) there is fitted an end piece (2), the base surface of which in line with the side transom (1) being approximately triangularly shaped. In the position for use of the side transom (1), one side of the end piece (2) in this case forms a horizontally or vertically aligned bearing surface. Also provided, in the inner chambers of the side transom (1), are screw channels (5), into which screws (6) passing through the end piece (2) are screwed. A bevelling off of the end faces of the side transom is no longer necessary, so that simple cutting to the appropriate overall length suffices. This results in considerable cost advantages both with regard to production and with regard to assembly. <IMAGE>

Abstract: At least one detector element (1) of cadmium mercury telluride or other infrared-sensitive semiconductor material is sandwiched between a substrate (20) and a lens plate (10) or other optical element. When an adhesive layer (11) is used to secure the lens plate or substrate over the detector element (1), there is found to be an unexpected decrease in cut-off wavelength and increase in junction resistance. In experiments leading to the invention, these changed characteristics were found to result from stress induced in the semiconductor material (1) by contraction of the adhesive (11) which led to a change in the energy bandgap of the semiconductor material (1). The stress is reduced and changes in characteristics minimised by adopting a slotted layer structure 1 and 8, in which the element body (1) is part of a wider layer (1 and 8) of the semiconductor material which occupies a majority of the volume around the element body (1) between the substrate (20) and the optical element (10). A slot (9) laterally separates the element body (1) around at least a majority of its periphery from the remainder (8) of the layer.
