Abstract: 1,264,357. Weighing apparatus. RELIANCE ELECTRIC CO. 10 Dec., 1969 [16 Dec., 1968; 23 Dec., 1968], No. 60378/69. Heading G4H. In apparatus for obtaining a load of a predetermined weight, e.g. 2875 units, in which a signal representing the weight on a scale 10 (Fig. 4) together with a preset signal e.g. 75 units is compared with a signal representing the required weight, at coincidence, i.e. when the scale has a load of e.g. 2800 units, the rate of feed of material to the scale is slowed down. As described the required weight is set up on selector switches (18, Fig. 2, not shown) to which are connected the outputs of counters 12, 13, 14, 15 connected to an analogue/digital converter 11 digitizing the weight on the scale 10. Initially a button 32 is pressed and the slider of a potentiometer 28 is operated until the required preset signal i.e. 75 in the embodiment described, is indicated on indicators 33. The button is then released and a second button 34 is pressed and the slider of potentiometer 29 is operated until a second preset signal representing the amount from the required weight e.g. 5 units at which the feed is to stop is indicated. Button 35, 36 are next sequentially operated to set up on potentiometers 30, 31 the amount of allowable under and over tolerance. In operation, the output of potentiometer 28 is first connected via switch 38 to the analogue/ digital converter 11 by a programmer 37 until the coincidence signal is generated to slow down the feed when the second potentiometer is switched in. At coincidence of the required weight and the sum of the input weight and the output of potentiometer 29 the feed is stopped and the output of the third potentiometer 30 is added in to the converter. With an under tolerance of 3 units, provided at least 2872 units are on the scale i.e. with at least an output of 2875 units from the converter a coincidence circuit (Fig. 3, not shown) is operative to generate a cutoff signal 23. If this signal is not generated an error light is lit. The fourth potentiometer 31 is then switched in and with an over tolerance allowance of 3 units if more than 2878 units are on the scale the coincidence circuit will still generate an output and an error light is lit. If no coincidence signal is generated at this time the value of the load on the scale is printed. The apparatus may be modified to weigh several successive ingredients (Fig. 5, not shown).

Title: Identification of signalling lines in telegraph multiplexing
IPC: H04L5/00
Filed: 1971-12-29
Abstract: 1329660 Digital transmission; multiplexing SPERRY RAND AUSTRALIA Ltd 29 Dec 1971 60452/71 Heading H4P In an arrangement for multiplexing a plurality of, particularly telegraph, lines on to a processing computer, each line is connected to a bistable device which is set on the occurrence of a transition, the devices being searched when a transition has occurred to ascertain which device or devices causes an identifying address(es) being sent to the computer. The line units may be arranged in a matrix with selection signals being applied simultaneously to rows and columns causing an output signal to identify the particular cross-point(s). Each active line may be located by successive halving of the number of devices and a test applied at each stage, the priority of the first half to be searched being predetermined. The computer may be duplicated together with line units and control circuitry. Preferably all traffic is offered to both computers so that input switching is avoided but a faulty computer output is blocked from the lines. Transitions may be extracted by a Schmidt trigger circuits or relays. In the matrix a group of six gates 1-6 are associated with the first row and 7-12 the last row, lines CS being associated with columns, lines RS with rows and line MC supplies a matrix clearing signal. Gate 4 provides a logical OR of the RR outputs of all line units in a row and gate 5 AND's this with the RS signal for that row. Gates 1, 2 provide a row clear RC to a row of line units from AND gate 2 receiving MC, RS signals, and gates 13, 14 provide matrix request MR and matrix data MD signals. As soon as a transition occurs on any line as indicated by an output from MR half of the CS, RS inputs are selectively disabled and if MR output indicates this is the correct half a further halving takes place. If signal MR disappears the opposite half is selected. Should more than one bistable be set these will be selected according to a predetermined programme. The conversion between telegraph signals and computer characters is carried out in the computer as is also any synchronization but the output is not synchronized and any convenient timing relationship may be adopted. The data transferred to the computer comprises a single 18 bit computer word for each transition which contains the address of the line concerned and the state of the line following the transition; the input to the computer thus comprises a stream of transition words each including an identifying address the timing being provided by a clock providing artificial transition words which effectively partition the input word stream into batches, but time resolution within each batch is not attempted. Timing is provided by a clock signal on one input in lieu of a telegraph line.
