IPC: G06F3/023
Filed: 1968-11-21
Abstract: 1,252,914. Data store; associated working of tape recorders with typewriters. STENOGRAPHIC MACHINES Inc. 21 Nov., 1968 [8 Dec., 1967], No. 55244/68. Headings G4C and G5R. [Also in Division B6] A stenographic typewriter (see Division B6) generates an electrical output representative of phonetic characters which is recorded on tape in the form shown in Fig. 13, the clock pulses each corresponding to a character and the character pulses representing the characters in a particular recorded word. The typewriter includes electrical contacts corresponding to the keys thereof, depression of a combination of keys representing a word causing generation of pulses which are stored in capacitors (202), Fig. 14, not shown. A commutator (Fig. 12, not shown) rotates for each word and generates clock pulses in alternation with either character pulses from a capacitor (202) or a smaller trigger  pulse. Each clock pulse energizes a first flipflop including transistors 380, 400, Fig. 15, to energize a clock pulse recording winding 453, and each trigger pulse de-energizes the first flip-flop. A character pulse also de-energizes the first flip-flop but in addition energizes a second flip-flop including transistors 480, 487 to energize a character pulse recording winding 520. A circuit is provided to energize a motor 130 of the tape recorder in response to an incoming cycle of pulses, and to de-energize the motor when the cycle is complete. The recorded phonetic word may be read into a computer for comparison with stored representations of literal equivalents and grammatical rules so that a literal transcription may be printed out.

Abstract: 1325725 Sealing thin-walled containers with lidding material PLASTONA (JOHN WADDINGTON) Ltd 19 July 1971 [18 July 1970] 34941/70 Heading B8C In a method of heat-sealing thin-walled containers each having a top peripheral flange a queue of containers is moved pasta sealing head 16 and lidding material 26 is lapped round a heated sealing roller 20 before being pressed by the latter into sealing contact with the container flanges. As shown, a chain conveyer, having a series of platens each with recesses to hold four thin-walled containers, carries, along its upper reach, a queue of containers, two deep, beneath the heated roller 20 which is supported in spring-loaded brackets 22 to urge the roller 20 resiliently on to the platens 10 as they pass beneath the sealing head 16. Unprinted lidding material 26 from a roll passes over an idler roller 28 and is fed between guide plates 30, 32 so that it laps round the roller 20 at an angle of approximately 70 degrees before it comes into contact with the container flanges. The lidding material may be a clear unprinted web of cellulose material coated on its underside with a hot melt adhesive, the roller 20, made for example of bronze, and heated to approximately 120‹ C., progressively heating the material before it contacts the container flanges. The containers are made of vacuum formed polystyrene. A transverse cutter blade drum, not shown, rotatable about an axis 38 is driven, by the chain conveyer drive and gears 34, 36, to cut between each successive pair of lidded containers. A longitudinal cutter may also be provided. Extra pressure may be applied downwardly to the roller 20 while the transverse seals are being effected by a cam and lever mechanism 40, 42, 44 driven by the cutter drum. A cam 55 and bellcrank mechanism 56, 52 can be operated by manually moving a lever 60 to raise the head 20, 22 against its spring which can be adjusted by nuts 64, 64. The containers may be ejected as they pass around the sprocket 12. If high temperature heat seal lacquer is used the roller 20 is heated in the region from 180- 210‹ C. and the angle of lap of the lidding material round the roller could be as little as 20 degrees. The roller 20, is provided with printing error compensation when the lidding material has repetitive printing matter, and it may be recessed to provide pressure only at the sealing areas. A barrier material may be provided between the roller and the lidding material instead of recessing the roller.

Abstract: 1326392 Resistance-capacitor oscillators DOBSON PARK INDUSTRIES Ltd 8 Nov 1971 [14 Nov 1970] 54327/70 Heading H3T [Also in Division H2] A circuit arrangement for use with a device which requires to be conditioned before it is able to become conductive, such as a fluorescent lamp 12 having heatable electrodes 11, comprises an inductor 13 in series with, and a capacitor 14 in parallel with, the lamp, which two elements are arranged to be resonant at a predetermined frequency, the arrangement including a supply source in the form of an inverter, the inverter being arranged to have a low output voltage-say 30 volts-at the predetermined resonant frequency of the elements 13, 14 which frequency may be 1500 Hz, the inverter being provided with means such that it produces a high output voltage-say 110 volts at a frequency-say 1000 Hz-lower than the predetermined resonant frequency of the elements 13, 14. Thus at starting of the lamp the output voltage of the inverter is 30 volts at a frequency of 1500 Hz and since at this frequency the elements 13, 14 resonate, practically all the inverter output voltage is applied across the lamp 12 causing it to strike. When the output frequency of the inverter voltage drops to 1000 Hz the elements 13, 14 go out of resonance and although the inverter output voltage has risen to 110 most of this voltage is dissipated in the inductor 13, the potential difference across the lamp 12 being sufficient to maintain the conduction thereof. In one form (see Fig. 2) the inverter is in the form of an oscillator having a transistor 20, the collector load of which is in the form of a resistor 21 shunt by three phase shifting stages each comprising a capacitor 22 and a positive temperature dependent resistor 23. Thus as the resistors 23 warm up the output frequency of the inverter decreases and the collector voltage increases. The lamp 12 is supplied by the inverter through an amplifying transistor 27 and transformer 28. Resistors 24, 25 connect the base and emitter respectively of the transsistor 20 to earth and these may be made temperature responsive such that the increase in output voltage of the inverter takes place after the decrease in the output frequency.
