Abstract: A process for the preparation of silyl ketene acetals of the formulae,
     and
     from the reaction of a malonate compound with a triorganohalosilane in the presence of an alkali metal. The malonate compounds are dialkyl dialkylmalonates, bis(trialkylsilyl) dialkylmalonates, and dialkylmalonic acids. The triorganohalosilane is present in stoichiometric excess relative to the malonate compounds. Silyl ketene acetals are isolated and separated.

Abstract: Disclosed herein is a method for operating blast furnace, wherein, when charging coke and ore alternately from the furnace top to form alternate coke and ore layers for operation of a blast furnace, a coke layer is formed by charging coke of properties especially suitable for improvement of gas and liquid permeability of the coke layer to the central part thereof or an ore layer is formed by charging ordinary versatile type coke to the central part of the ore layer prior to formation thereof. The centrally charged coke forms a major part of the dead coke layer which is sequentially renewed under the cohesive zone of the blast furnace to maintain appropriate gas and liquid permeability of the dead coke layer, thereby enhancing the production efficiency and stability of the blast furnace operation while suppressing erosive wear of refractory walls of the furnace.

Abstract: The objects of the present invention are accomplished in general by a versatile general purpose hardware address permutation system for mapping logical to physical device addresses including the capability of selecting any one of a family of address permutation matrices, which produce address mappings which decrease contention associated with stride accesses and other problems. The resultant system allows uniform accesses for any power-of-two strides, but does not cause contention problems for other stride accesses. The matrices and resultant mappings are based on transformations that are linear over the Boolean field GF(2) and involve a bit-matrix multiplication of the target address with successive rows of the matrix. The hardware system is of significant value in primary and/or secondary memory systems of SIMD or MIMD machines, and can eliminate memory hot-spot problems associated with the stride access pattern of an application. The hardware required may be incorporated in the address translation unit of the host computer and comprises a storage unit for storing a plurality of different matrices, a bit-matrix multiplication module, means for storing the permuted address and a control unit for accessing a predetermined matrix under system control and transferring the matrix and the N-bit field of the address to be permuted to the bit-matrix multiplication module where N permuted bits of address are generated by the bit-matrix multiplication of the address with N successive rows of said matrix. The procedure described herein can easily be implemented in hardware or software and a method is described for incorporating such transformations in a memory mapping unit of a highly parallel processing system. While the present invention has primary utility in large random access interleaved memory systems, it would also be applicable to large I/O systems such as direct access storage devices that require fast data retrieval for database applications.

Abstract: An automated inventory management system is provided which is easy to use and user friendly to evaluate the impact of customer demand changes on inventory. For a given item, the system automatically defines an inventory model by accessing an engineering planning database. The system identifies the on-hand raw material inventory and evaluates the work-in-process inventory from the model. The system then accesses an inventory database to identify the finished goods inventory and automatically consolidates all inventory and computes the total impact. The system also provides the practicing manager necessary control limits on raw material and work-in-process inventory dollars to complete a given finished product and establishes the required inventory turns. The user can use the system to compare against acutals and take appropriate action to correct any process deficiencies. This provides the capability to evaluate inventory sensitivity to customer demand and can be used to better serve the customer and his needs.

Abstract: Hochfrequenz-Leistungsgenerator mit einem als Komplementär- oder Quasikomplementärstufe aufgebauten Leistungsverstärker (1), der im Schaltbetrieb arbeitet, und der eine Lastimpedanz (ZLAST) über ein aus einem Serienresonanzkreis und einem (Ls, Cs) Parallelresonanzkreis (Lp, Cp) gebildeten Ausgangsfilter speist. Im Moment des Anschwingens wird die Steuerspannung für den Leistungsverstärker von einem Hilfsoszillator (7) geliefert. Nach dem Anschwingen wird die Ansteuerung des Leistungsverstärkers (1) auf Rückkopplung aus dem Ausgangskreis, d.h. Selbsterregung umgeschaltet. Dabei wird die Rückkopplungsspannung aus dem Ausgangsstrom des Leistungsverstärkers (1) gewonnen, wenn die angeschaltete Lastimpedanz (ZLAST) einen charakteristischen Wert unterschreitet, und aus der Ausgangsspannung, wenn die Lastimpedanz (ZLAST) diese charakteristische Impedanz überschreitet. Der Vorteil dieses Hochfrequenz-Leistungsgenerator liegt in einem sehr stabilen Betrieb auch bei sehr stark schwankenden Lastimpedanzen und bei einem Fehlabgleich des Ausgangsfilters. Die Verlustleistung in den Verstärkerelementen ist minimal, der Wirkungsgrad ist sehr hoch.

Abstract: A hydraulic circuit system for a vehicle height control device is provided comprising actuators (1FL, 1FR, 1RL, 1RR) for increasing and decreasing vehicle heights as respective results of the supply and the discharge of working fluid to and from their working fluid chambers (2FL, 2FR, 2RL, 2RR), a supply passage means (18) and a discharge passage means (32) for supplying and discharging working fluid to and from the chambers, respectively, control valve (28, 58, 76, 42) means for controlling the supply and the discharge of working fluid, cut-off valve means (26, 56, 74, 90, 42, 70, 88, 104) provided in the supply and discharge passage means and adapted to remain in their closed position so long as the pressure within the supply passage means is not more than a predeterminate value. The system further comprises a bypass valve means (49) for selectively communicating the supply and the discharge passage means with each other so that the pressure within the supply passage means may be controlled. The opening and closing of the cut-off valve means can be performed by solely controlling the bypass valve means, thereby reducing the electric power required to operate the system. Undesired decrease in vehicle height can positively be prevented by the cut-off valve means even in the event where the control valve means is shifted for supplying the working fluid to the chambers under the condition where the pressure within the supply passage means is relatively low.
