Abstract: 1,265,153. Photo-electric measuring. COAL INDUSTRY (PATENTS) Ltd. June 20, 1969 [March 22, 1968], No. 14015/68. Heading G1A. The flow-rate of material in liquid or in divided or particulate form is determined by allowing the material to fall through a beam of electromagnet radiation of known cross-sectional dimensions and intensity, and employing means to indicate the amount of the radiation absorbed by the material per unit time. Divided coal falls in a stream 1 from a conveyer 2 on to a second conveyer 4 and X-rays, preferably gamma rays, from a single beam source 6 are detected by a detector 10. The instantaneous flowrate is determined by measuring the radiation detected at detector 10. Total weight over a given period is determined by integrating the product of the rate and velocity with respect to time. Source decay is continuously catered for by a clock mechanism which causes progressive lowering of the source 6 and/or detector 10 at a constant slow rate thereby increasing the mean velocity of the coal through the beam 8. The coal thickness at the delivery end of conveyer 2 may be measured by trailing fingers (not shown). The flow rate of heterogeneous material is determined by two or more beams of short wavelength X-rays of different wavelengths generated by X-ray tubes. Variation in intensity of the beams detected due to variation in the output from the X-ray tubes with time is automatically monitored by the interposition of a standard plate giving constant radiation obscuration and the positions of the source and detectors adjusted automatically by servomechanisms. With large streams of falling material a plurality or sources and detectors of electromagnetic radiation are used.

Abstract: 1290984 Digital data exchanger SIEMENS AG 1 Sept 1970 [2 Sept 1969] 41752/70 Heading H4P In a programme-controlled digital data exchange processing units, such as line units, metering units, are allocated central-store cycles according to the priority of the unit, any unit being able to select a higher than its usual priority for special conditions, such as fault conditions, to give a faster access to the store. Processing units VE1-VE5 transmit a first call-up signal AB, demanding access to the store S, to a store application control circuit SAFS over lines Stk1, where a priority logic circuit AS (Fig. 3b, not shown) determines the highest priority of any simultaneously calling processing units. A second signal ZA from a calling unit causes the identity of the highest priority calling unit to be sent through to the store control SOPS. An acknowledgment signal ZQ is returned to the successful unit, which is now connected via channel Dk with the store for the exchange of data. If a unit uses its special priority, a signal SP is sent on lines Stk4 to a priority unit PL which modifies the priority rules of unit AS. An acknowledgment signal QP is sent to the calling unit. The special priority can be withdrawn by a calling unit before its connection to the store by transmission on lines Stk4 of a special signal. The priority control circuit PL contains ring-hunting- selectors. one for each special priority, with the processing units arranged in each selector in the order of their normal priorities, so that if several processing units are simultaneously seeking the same special priority they are still dealt with in the order of their normal priorities. A monitoring unit UW ensures that no single unit with a high priority can monopolize the store above a certain number of consecutive calling applications, and also times the signalling exchanger between processing units and store control units and between the store control units and the store to detect any fault conditions.
