Patent GB-2102344-A (GB)
Title: Cooler for printing machine
Inventor: FISCHER HERMANN
IPC: B41F23/04
Filed: 1982-07-16
Abstract: The cooler (7) which is located downstream of the drier (6), itself located downstream of printing units (3, 4, 5), comprises cooling rollers (9, 10, 11), at least two (9, 10) being positionable apart or against one another and are constructed as calendering rollers so that the web (2) running between them can be both cooled and calendered. The difference in the web path-length caused by the displacement of the roller (9) between its two positions, is compensated by two rollers (12, 13) arranged to operate simultaneously to change the path length so that the overall path- length remains the same. Alternatively, the displaceable roller may be arranged for movement that does not alter the web path-length. Two pairs of cooling/calendering rollers may be located one above the other like the four cylinders of an offset two-sided printing unit enabling similar side walls to be used for the cooler as for the printing unit. <IMAGE>

Title: Circuit arrangement for transmitting digital signals in a communication system, particularly in a PCM telephone private branch exchange
Inventor: SCHILL ALFRED
IPC: H04J3/06
Filed: 1982-11-05
Abstract: If, in a digital communication system, e.g., a PCM private branch exchange, signal bits are transferred between two functional units, delays may occur on the transmission lines (üL) and in the gates (LE1) and cause switching errors. To eliminate the need to adjust the delays in each exchange by special delay elements, a compensating circuit (AGL) containing several multiple D flip-flops (FF1, ..., FF4) is provided at the receiving end. The writing and reading of the signal bits into and from the flip-flops is controlled by two shift registers (SR1, SR2) which are clocked by the transmitting clock and the receiving clock, respectively, and are placed in a defined output state by the respective frame synchronization pulses. Delay compensation is thus performed automatically. <IMAGE>

Title: Apparatus for and method of random vibration control
Inventor: LAX DAVID RICHARD
IPC: G01M7/00
Filed: 1983-01-26
Abstract: In order to ensure that the vibrations of a system under test (12) are in accordance with a reference spectral density Z(w), the system (12) is driven by a signal x<sub>n</sub>(t) provided by an inverse discrete Fourier transform (24) with random phases introduced by a function R<sub>n</sub>(w) and the response spectral density Y<sub>n</sub>(w) provided by a DFT 16 is brough into agreement with Z(w) by a feedback loop. Moreover, in order to ensure that this is done in one iteration, X<sub>n</sub>'(w) is derived from x<sub>n</sub>(t) by a DFT (26) and divided (28) by Y<sub>n</sub>(w) and the quotient is multiplied (30) with Z(w) to provide the new input X<sub>n</sub>(w) for the IDFT (24). The division cancels out the random factor which is present in both X'<sub>n</sub>(w) and Y<sub>n</sub>(w). The system thus equalizes both rapidly and stably.

Patent GB-2131581-A (GB)
Title: Dual processor arrangement
Inventor: OGDEN RICHARD JOHN
IPC: G06F13/36
Filed: 1983-11-08
Abstract: A data processing system includes microprocessors 10 and 11. The microprocessor 10 normally accesses a bus 12 but sometimes needs to access a bus 13. The microprocessor 11 only accesses the bus 13. When it wishes to do so it issues a request signal REQ on a line 18 and proceeds with the access when it receives an acknowledgement signal ACK on a line 19. During the times when the microprocessor 10 does not wish to access the bus 13 it sets a bistable 20 and subsequent request signals from the microprocessor 11 are switched straight back as the acknowledgement signal by a gate 21 which connects the line 18 to the 19. When the microprocessor 10 wishes to access the bus 13 it tests for the presence of a request signal from the microprocessor 11 (which is maintained during an access) and only if it is absent clears the bistable 20, prevent subsequent requests being acknowledged and allowing the microprocessor 10 to access the bus 11.   <IMAGE>

Title: Reducing grain in multi-phase-clocked ccd imagers
Inventor: BATTSON DONALD FRANKLIN
IPC: H01L21/339
Filed: 1984-03-05
Abstract: Grain, a fixed pattern noise which is not attributable just to dark current variations in the imager and which persists even in relatively bright images, is reduced in a CCD imager with three-phase-clocked imager register by introducing an offset potential (VINT) at the gate electrode (12, 15, 18) between that biased for charge integration (13, 16) and that biased to prevent accumulation of charge, the offset potential lying between the bias values of the adjacent electrodes. The intermediate electrode is conventionally held at the low potential of the non-accumulation electrode but the invention causes all the charge occurring under the intermediate electrode to migrate to the same potential well, thus reducing grain. In field transfer type CCD imagers, using field interlace and three-phase image-register and field-store-register clocking, the offset potential can be made large enough, not only to reduce grain, but to improve field interlace from two-thirds field interlace towards or to perfect field interlace. <IMAGE>
