Abstract: 1,186,857. Acoustic measurement of temperature; ultrasonic couplings. STEEL CO. OF WALES Ltd. 21 March, 1968 [31 March, 1967], No. 54131/66. Headings H4D and H4J. The temperature of a medium is determined from the propagation time of an ultrasonic wave transmitted through the medium. For measuring the temperature of a specimen 10, e.g. a steel bar on a rolling table or a slab in a re-heat furnace a pair of transducers 30 are coupled to the specimen by extension bars 14, 15 in watercooling jackets 17. Studs 25 enable bars 14, 15 to be urged against the specimen 10. A material which softens but does not melt (e.g. grease) may be used as couplant between the bars and the specimen. The propagation time in the extension bars 14, 15 is determined by a pulseecho method using one of the transducers 30 and an oscilloscope: the propagation time in the bars plus the specimen is determined by a through-transmission method using both transducers and the oscilloscope. From these determinations the specimen temperature can be calculated.

Abstract: 1285591 Data transmission GRI COMPUTER CORP 6 Nov 1969 [29 July 1969] 54496/69 Heading G4A Digital binary data is transferred from a source bus 20 to a destination bus 22 by way of a transmission link 24, in which the data is capable of being transmitted only in the following modes: (a) unchanged; (b) arithmetically incremented by one bit; (c) shifted left by one bit or (d) shifted right by one bit; the whole system being controlled by a microprogram store control device (26, Fig. 1, not shown). The bus 20 receives data from data sources (e.g. transducers, memories) and the bus 22 sends the data to data processors (e.g. arithmetic or control units), alternatively the data flow can be the other way. The data busses can be serial or parallel (four or sixteen bits, each line corresponding to one binary order) and the link 24 can also complement the data and has provision for overflow (Fig. 2, not shown). The control device.-It comprises an instruction register 44, a read only memory 46, a gating circuit 48 and a sequence register 50. A source memory 52 (e.g. core, drum or tape) stores a number of 16 bit instruction or data words, the instruction words each comprising a six bit destination address, four operation bits, and six source address bits; while the data word comprises one sign bit and fifteen data bits. Two of the operation bits specify which of the alternatives (a) to (d) is intended. An instruction goes to instruction register 44 under the control of the read only memory matrix 46 which can be sequenced through a number of major states by a clock 64, each major state having four time intervals To to T 3 . For example for state FI (fetch instruction), during To, memory 46 informs gate 48 that register 50 is the source, the path is (a), and a memory address register 54 is the destination. During T 1 , the information in the memory buffer 56 is taken through path (a) to the input of register 44. During T 2 , the read only memory gives an execute signal and during T 3  the sequence register is increased by one by passing its contents through path (b). Paper tape readers and punches are also mentioned.

The spring 8 maintains the piston 3 in position against the pressure in A during contact opening until a predetermined value has been reached, at which point it yields allowing the pressure in B to increase. This is stated to give an improved P/V characteristic as indicated in curves given in Fig. 4 (not shown) and thus reduce the arc-quenching time. When the contacts part and quenching gas, e.g. SF 6 , is discharged on to the arc, the fall in pressure in A is partly compensated for by the opening of the valve 9.
