Abstract: A method and apparatus for minimizing memory read latency in a digital computer system which includes a system control unit (SCU) with an associated main memory, and a plurality of independent central processing units (CPU's), each CPU having an associated writeback cache. Data requests from a requesting CPU start a normal read cycle in the SCU main memory, and the data read requests concurrently begin a search for the location of any modified version of the requested data in the SCU data storage location directory, which stores the location of modified data located in both the SCU main memory and the caches of all the CPU's. The SCU main memory read cycle is aborted if a modified version of the requested data is found in any of the CPU caches, and the modified version of the requested data is then passed from the located CPU cache and through the SCU to the requesting CPU as read data.

Abstract: A train of data blocks each carrying digital data and ID data are produced from reading head as a tape passes the cylinder. A memory (10) having a plurality of sections (Y0, Y1, ...) is provided, and a plurality of counters (C0, C1, ...) are provided correspondingly to the sections. The digital data are stored in a memory (10) at a second identified by the ID data. Each time the digital data for one block is stored in a section in the memory, a counter corresponding to that section is incremented, and each time the digital data for one block is read out from a section in the memory, a counter corresponding to that section is decreased. Thus, as long as counter repeats "0" and "1", the data block is properly stored and properly read. However, if any one of the counters shows a number other than "0" and "1", it is understood that the writing or reading is carried out twice in a row for the same section in the memory. Thus, error in the ID data can be detected.

Abstract: A first transistor (16) is connected in grounded-collector-emitter-follower configuration to generate a high enough negative resistance to overcome the oscillating resistance of a crystal resonator (10) connected to the base electrode. A second transistor (43) connected in grounded-base configuration serves as a buffer and impedance transformer between the low impedance output of the first transistor and the high impedance of a load. An inductor (12) connected between the resonator and the first transistor input and a variable capacitance (24, 25, 26) approximating the shunt capacitance (11) of the resonator connected across the first transistor input form an impedance inverter which absorbs the resonator shunt capacitance and converts the effect of the resonator to a parallel tuned circuit that can be broadly tuned.

Abstract: A method is provided for separating hydrogen fluoride (HF) from a mixture comprising HF complexed with an aromatic ketone in which the keto carbon atom is directly bonded to an aromatic ring carbon atom, e.g., 4-isobutylacetophenone, by adding a carboxylic acid anhydride, e.g., acetic anhydride, to the mixture while maintaining the mixture at conditions sufficient to sustain a reaction between the anhydride and the HF to form the corresponding acyl fluoride, e.g., acetyl fluoride, and carboxylic acid, e.g., acetic acid, and separating the acyl fluoride from the mixture. The method is conveniently carried out in a stripping column near the top of which the mixture comprising aromatic ketone and HF is fed and below which the anhydride is fed. Between these feed points, the uncomplexed HF is stripped from the mixture, while below the anhydride feed point or points, the anhydride reacts with the complexed HF to form the acyl fluoride which is stripped from the mixture, and the carboxylic acid. The separation method may be integrated with the production of the aromatic ketone by the Friedel-Crafts acylation of an aromatic compound, e.g., isobutylbenzene with an acyl fluoride, a carboxylic acid anhydride, a free carboxylic acid, or a mixture of the foregoing reactants, using an excess of HF as catalyst, to produce the mixture comprising aromatic ketone and HF to be separated, and to which the separated HF and in some cases the acyl fluoride may be recycled.

Abstract: The problem forming the basis of the invention is to transmit a frequency-division multiplex signal which covers a wide frequency band, for example the cable television frequency band from 47 to 440 MHz, via an optical fibre transmission link. According to the invention, the entire frequency band to be transmitted is divided into two sub-bands (FB1, FB2) in the transmitting device, and the lower sub-band (FB1) is converted by single-sideband amplitude modulation of a radio-frequency carrier (f0) into a higher-frequency transmission frequency band, for example 497 to 688 MHz which, referred to its lowermost frequency, is less than one octave wide. The lower sub-band (FB1) and the transmission frequency band obtained by the conversion are separately converted into optical signals having different wavelengths ( 1, 2) and transmitted in wavelength-division multiplex via the optical fibre. Due to the limitation to less than one octave, second-order intermodulation products which normally occur during the conversion into an optical signal fall into frequency ranges which are not occupied. At the receiving end, a corresponding processing occurs in the reverse order.
