Title: Method and an arrangement for measuring the pulse sequence frequency of a pulse sequence
IPC: G01R23/10
Filed: 1974-10-17
Abstract: 1482158 Digital frequency measurement TELDIX GmbH 17 Oct 1974 [23 Oct 1973] 45096/74 Heading H3H Digital measurement of the frequency of pulses input at 11<SP>1</SP> is obtained by counting clock pulses, generated at 32, in a backwards counting counter 31 for a whole number of periods of the pulses input at 11<SP>1</SP>, said whole number being automatically selected so that the count in counter 31 reaches at least a predetermined number, and the frequency of the clock pulses being varied in proportion to the reciprocal of the square of the period of the input pulses at 11<SP>1</SP>. The pulses from 11<SP>1</SP> are counted in a second backwards counting counter 34, circuit 22<SP>1</SP> giving output pulses when counter 34 has counted 1, 2, 4, 8 &c. pulses from 11<SP>1</SP>, and the next pulse from circuit 22<SP>1</SP> following the setting of flip-flop 5<SP>1</SP> by counter 31 reaching the predetermined number blocks further counting in both counters and transfers their counts to stores 35 and 36, the counters and flip-flop 5<SP>1</SP> being then reset. Circuit 37 divides the content of store 35 by the content of store 36, by positional shifting, to give the required frequency-measuring signal.

Abstract: 1485274 Solid/liquid contact J R BENZARIA 22 Oct 1974 [22 Oct 1973] 45610/74 Heading B1F [Also in Division C1] A process for the absorption of a component of a fluid on beds of activated carbon comprises passing the fluid through a lower bed of activated carbon at a rate sufficient to maintain that bed fluidised, and then through an upper fixed or expanded bed at a flow rate in a ratio of not less than 1 to 10 with respect to the flow rate in the lower bed, the ratio of flow rates being determined by the ratio of cross-section areas of the beds. As shown the fluid is passed first through the narrow bed 2 in which its velocity is sufficient to fluidise the particles and then through the wider bed 3 in which the velocity is insufficient to produce fluidisation but may maintain the bed in an "expanded" condition. The process is applicable to the purification of water.

Abstract: 1488067 Regeneration of activated carbon ASAHI KASEI KOGYO KK 5 Nov 1975 [7 Nov 1974] 45899/75 Heading ClA Used, activated carbon having oleophilic and/or hydrophilic adsorbates adsorbed thereon is regenerated by contacting it with liquid dimethyl ether or a liquid mixture of dimethyl ether and water to desorb the adsorbates. Hydrophilic adsorbates may be more rapidly desorbed using aqueous dimethyl ether solutions with preferred weight ratios of 0À5 to 50 g of dimethyl ether to 0À1 to 25 g of water per gram of the used activated carbon. Typical contact times are 0À5 to 60 mins. Contact may be effected by agitation or column extraction under conditions sufficient to keep the ether liquid, e.g. 3-5 kg./cm.<SP>2</SP> at room temp., or -25C. at atmospheric pressure. The regenerated carbon may be filtered from the desorption liquid and the ether evaporated to recover the desorbed adsorbates.

The clock mode is initiated by pressing the recall key RCL 118 Fig. 1, followed by the enter key 116, a time being entered with the digits displayed on a light emitter diode display to the left of the decimal point representing hours, the first two digits to the right representing minutes, the next two digits representing seconds and the last two digits representing hundredths of seconds. Operation of a change sign key CHS and an enter exponent key EEX toggles the clock and blanks/ unblanks the hundredths of a second display respectively. The summation key stops the clock and it is zeroed by operation of a clear X key CLX. Split times are stored by operating a digit key which results in a time being stored in a storage register of the same number as the digit of the pressed key. Consequently the calculator may be used as a stop watch for a race by pressing digit keys as each competitor crosses the finish line. Further operation of digit key recalls the stored times. The clock mode is based on the fact that the hundredths of a second count should be incremented every 35 instructions so that in the clock mode each programme loop Fig. 4 (not shown) is made after 35 instructions in length by including a loop dependent delay with no-op code or other instructions not related to operation of the clock.

Abstract: 1,019,416. Fault testing. G. GERBIER and J. P. BERGER. Dec. 6, 1963 [Dec. 7, 1962], No. 48324/63. Heading G1U. Logic circuit units having any number of terminals less than some given maximum number, are automatically tested by comparison of the output signals with those from a standard unit when input signals are simultaneously applied to both units. The tester comprises a counter 5, having trigger stages 5 0 ....5 N , which is stepped on by a pulse generator 4, exclusive OR circuits 3 1 ....3 N  and relays 7 1 ....7 N . The unit under test 1, and the standard unit 2 are connected to the tester, and a programme card 70 is inserted to actuate the relays 7 whose contacts are connected to input terminals of the units under test (as shown relays 7 1  .... 7 N-1 ), the remaining relays being associated with output terminals of the units. As the counter steps on, signals are applied sequentially to the inputs of the logic units via the front contacts of the relays 7 1 .... 7 N-1  and the outputs from the units are fed via the back contacts of relay 7 N  to exclusive OR circuit 3 N . As long as both outputs are the same, no output is produced from circuit 3 N  and the counter continues to step. If due to a fault a difference occurs the output from the circuit 3 N  is fed via OR-gate 40 to the pulse generator 4 and stops the switching cycle. Lamp 51 and some of lamps 50 1  .... 5 N  are lit indicating where the fault occurs. If the cycle is completed lamp 50 0  is lit. If an input element is short circuited, the fault is shown by the presence of a signal at the output of one of the AND gates 60 1 .....60 N  which is fed to the pulse generator via OR gate 6, to stop the switching cycle. Where two consecutive terminals are connected to a trigger circuit, false signals are prevented by inserting a further programme card 54 which energizes some of the relays 53 1 ....53 N  (53 N-2 , 53 N-1  as shown) so that the signals applied to inputs 10 N-1 , 10 N-2 , 20 N-1 , 20 N-2  are inverted. In order to detect differences in response times between the two circuits the pulse generator 4 may be modified Fig. 4 (not shown) by the inclusion of a further pulse generator, which is so arranged that a gate is opened and the counter is stopped if the time difference between the outputs from the units 1, 2 exceeds a predetermined value.
