Abstract: PCT No. PCT/EP85/00666 Sec. 371 Date Jun. 6, 1986 Sec. 102(e) Date Jun. 6, 1986 PCT Filed Dec. 4, 1985 PCT Pub. No. WO86/03438 PCT Pub. Date Jun. 19, 1986.The subject matter of the invention is a device for supplying spray units for die casting machines each with a fluid containing water and additives for cooling, cleansing and lubricating purposes. The device contains at least one central tank (26,28) storing water comprising additives, whose concentration has been adjusted to a maximum. Said maximum value depends on casting materials, molds (18,20) and die casting methods which are carried out on the die casting machines (10,12). In another central tank (44) water is stored. The tanks (26,28,44) are connected to mixing valves (38,40) provided at each die casting machine (10,12). A pump is connected between the outlet of each mixing valve and the inlet of a respective spray unit at a die casting machine.

Abstract: A multiplying digital to analog converter using ladder networks and binary weighted load compensation to allow integration and video frequency operation. In one form, the circuit is configured from field effect transistors which incorporate by virtue of their structural and operational characteristics both the switching and resistive functions of R-2R ladder networks. The circuit is used to convert digital format words representing intensity and color (red, green and blue) into analog red, green and blue display drive signals. According to that configuration, the output of the digital to analog intensity word converter serves as the reference for the three digital to analog color word converters. Loading effects attributable to differences in the bit content of the color words are offset by a binary weighted switched load which is responsive to a digital compensation word. The switched load is also connected to the output of the intensity word converter. This circuit configuration provides an implementation by which the color (hue and saturation) in analog form can be held constant while the intensity of the color is selectively varied.

Abstract: In the production of hollow bodies from oriented thermoplastic material, a cylindrical portion of a heated hollow preform is stretched, with a simultaneous reduction in the wall thickness thereof, at a starting temperature below the vitreous transition temperature of the material. A mandrel is positioned in the preform to support it during stretching, the outside diameter of the mandrel corresponding to the inside diameter of the preform. Directly before the mandrel is inserted into the preform the preform is subjected to re-alignment to adapt at least the cross-sectional shape of the mouth opening of the preform to the cross-section of the mandrel. The re-aligning operation is effected by inserting the preform into a sleeve adjoining a drawing ring for carrying out the stretching operation.

Abstract: An optical signal regenerator comprises an optical coupler (1) having a first input (2) for an optical information signal, a second input (3) for optical clock pulses and an output (4) for a combined signal, and a resonant laser amplifier (5) downstream of the output (4) of the coupler (1) and arranged to receive the combined signal and, in use, output a regenerated optical information signal. The bias current applied to the laser amplifier (5), in use, biases the amplifier (5) to a level below its lasing threshold, and the power of the optical clock pulses is just below the bistable threshold of the amplifier, so that, when an optical information signal is fed into the first input (2) during the application of an optical clock pulse to the second input (3), the bistable threshold of the amplifier (5) is exceeded causing a sudden jump in the power of the optical output of the amplifier to provide a regenerated optical information signal.

Abstract: Un procédé, servant à acheminer un milieu en suspension électro-conducteur, tel que de la peinture, à partir d'un système de stockage (11) via un conduit d'alimentation jusqu'à une station de consommation (11), dans laquelle est incorporé un dispositif de distribution (29) pouvant être chargé de façon électrostatique, tel qu'un pistolet vaporisateur de peinture, en vue d'un traitement d'unités par exemple à la peinture, consiste à acheminer ledit milieu dans un lieu de stockage intermédiaire faisant partie du conduit d'alimentation et situé entre la station de consommation et le système de stockage, ledit conduit d'alimentation pouvant être interrompu électriquement et physiquement entre le système de stockage et le lieu de stockage intermédiaire au moyen d'une unité d'interruption. Le but dudit procédé est d'empêcher la charge électrostatique se trouvant dans le bec du vaporisateur d'être transférée dans le système de stockage de l'installation de peinture. A cet effet, le milieu est pompé depuis le système de stockage via un premier conduit d'alimentation jusqu'à une première partie de robinet fermée faisant partie de ladite unité d'interruption, dont la seconde partie de robinet, connectée à un second conduit d'alimentation, établit par interconnexion avec lui une connexion fermée du milieu entre les conduits d'alimentation. Le milieu est pompé durant la période d'interconnexion des parties de robinet jusque dans le lieu de stockage intermédiaire, ce qui permet d'interrompre le chargement électrostatique, et, après déconnexion des parties de robinet, le milieu est soumis à une pression dans le lieu de stockage intermédiaire et est acheminé jusqu'au dispositif de distribution durant le chargement électrostatique.

Title: Memories and the testing thereof
IPC: G11C29/00
Filed: 1988-01-22
Granted: 1992-12-09
Abstract: A memory may contain a large number of bytes of data perhaps as many as 256 megabytes in a typical large memory structure. An error correcting code algorithm may be used to identify failing memory modules in a memory system. In a particular embodiment, a number of spares may be provided on each memory card allowing a predetermined number of defective array modules to be replaced in a storage word. With double bit correction provided by the error correcting code logic, a number of bits can be corrected on a card or a larger number of bits can be corrected on a card pair, where the larger number of bits is somewhat less than double the number of bits which can be corrected on a single card. The address test in accordance with the present invention then produces a pattern that will create a difference greater than that larger number of bits between the data stored in a storage location under test and any address that could be accessed by an address line failure. The method according to the present invention predicts the effect of an address line failure external to the array modules and internal to a card pair and then tests to see if a failure has occurred. The address test does not declare an address failure until a predetermined number of bit failures on a card is found. The test is valid for single and multiple address line failures. Since only one address bit is changed for each path through the test other failing address lines will not be detected until the path with those failing address bits are tested. Thus, even with multiple address line failure the two addresses that are stored to and fetched from are the only one address bit apart.
