Title: Circuit for rapid or boost charging accumulators
IPC: H02J7/00
Filed: 1971-12-10
Abstract: 1356609 Charging batteries VARTA AG 10 Dec 1971 [11 Dec 1970] 57556/71 Heading H2H A circuit for rapidly charging a battery from a source of pulsating voltage comprises a switch between the voltage source and the positive battery terminal, a two-state control circuit being provided to control the operation of the switch so as to terminate charging of the battery when the battery is fully charged. The source of pulsating voltage may be unsmoothed rectified A.C., either full or half wave rectified. A battery (not shown) is connected to terminals +, -, and is arranged to be charged from a pulsating D.C. source, derived from the unsmoothed output of a bridge rectifier, over a thyristor T1, Whilst the state of charge of the battery is below a predetermined value the potential tapped off a potentiometer P1 is such that a control circuit including transistors T2, T3, T4 assumes a first state in which all the transistors are non- conductive. With the control circuit in this state firing pulses for the thyristor T1 are derived by means of a resistor R2 and diode D2 with the result that the thyristor fires early in each half wave of the pulsating D.C. supply, the battery then receiving charging current whenever the instantaneous magnitude of the pulsating voltage exceeds that of the battery. As the charging of the battery proceeds and reaches a predetermined value, the potential derived from the potentiometer P1 becomes sufficient to fire the transistors T2, T3, T4 to place the control circuit in its second state. The firing of transistor T2 places the control electrode of the thyristor T1 at the negative potential of the battery thus inhibiting firing of the thyristor to terminate the charging of the battery. The control circuit may be overridden by manual operation of a switch Ta. Trickle charging may be obtained by means of a resistor R8 and diode D3 in parallel with the thyristor T1. A battery discharge circuit may be incorporated if required which circuit comprises a capacitor C2 and thyristor T6 which is triggered by a transistor T7 such that whenever the control circuit is in its first state with the transistors non- conducting the thyristor T6 is rendered conductive to discharge the battery except that when the battery has attained its predetermined charge the thyristor T6 remains cut off.

Abstract: 1396980 Measuring defects in seals electrically TOYO SEIKAN KAISHA Ltd 18 Dec 1972 [17 Dec 1971 25 Feb 1972 7 March 1972] 58265/72 Headings G1N and G1S A method of detecting defects in a seal 7a of a package 7 wherein one side of the seal is brought into thermal communication with a bar 1 at a temperature different from that of the seal and the resulting temperature of the other side of the seal is monitored, the temperature constituting an indication of the presence or absence of a defect in the seal. The seal may be hotter or colder than the bar. In a preferred embodiment the temperature is monitored by an array of thermocouples Fig. 2A (not shown), alternate junctions of which are in thermal communication with the seal and with a reference seal 8 which has no defect or is thermally equivalent to a defect-free seal. Alternatively Fig. 7 (not shown), there is no reference seal but the temperature detector (102) is divided into a plurality of groups of temperature sensors and the voltages from the thermocouples in each group are summed, the sum voltages from the groups being compared, Figs. 10, 13 (not shown), and an alarm being actuated in response to a difference between the sum voltages. The embodiments of Figs. 13 to 16 (not shown), utilize an electric resistance wire as the temperature sensor.

Title: Word recognition system with character string encoding
IPC: G10L15/00
Filed: 1973-12-19
Abstract: 1433770 Speech recognition systems XEROX CORP 19 Dec 1973 [5 Jan 1973] 58825/73 Heading G4R A speech signal, e.g. a word, is divided into n frequency bands, and in each of a number of successive time intervals the energy level in each band is used to define a set of n values which may be regarded as defining a point in n dimensional space. Thus the successive sets represent successive points on a curve in that space. Each set (point) is inspected to determine which of a number of reference sets (points) corresponds to that set and is assigned a 'label' representing that reference set. The resulting sequence of labels is compared with reference sequences derived from reference speech signals in order to identify the unknown speech signal with one of the reference signals. As disclosed the speech signal is divided into 6 bands by filters which feed an integrator. The integrator sums the energy in each band over successive periods of 10 m.sec. and feeds a processor via an analog-digital converter. The converter output represents the energy value of each of the 6 banks in each 10 m.sec. interval. Each set of 6 values defines a point in 6-dimensional space and the succession of points a curve, e.g. as the curve shown in Fig. 3 for a 3-dimensional space defined by frequency bands X, Y, Z. The processor normalizes the sets and determines which point of a number of reference points, e.g. p1-p8 in Fig. 3, is nearest to each of the sets of values, and labels the set with the label of that nearest point. In general the number of bits required to define a label is less than the number required to define a set of the values. The sequence of labels is compared with reference sequences as indicated above. Because speakers do not always sound the final stop consonants these consonants are ignored if they last less than 200 m.sec., so that their presence or absence is immaterial to the recognition process.

Abstract: 726,554. Wrapping-machines. FORGROVE MACHINERY CO., Ltd., and BROOK, L. Nov. 23, 1953 [Feb. 4, 1953], No. 3165/53. Class 94 (1). [Also in Group XXX] A machine for wrapping elongated tablets comprises an upper primary feed disc 10 haying tangentially-disposed, circumferentially-spaced elongated holes 12, and a lower secondary feed disc 13 having radially-disposed, circumferentially-spaced holes 14 of similar shape, the discs being arranged in overlapping relationship and rotated intermittently, as by gearing 15, 16, so that successive holes are brought into alignment at a transfer station X. Tablets are trickle fed on to the disc 10 from a trough 18 which receives a supply from a hopper 19 and is maintained in fore and aft vibration by an electromagnetic vibrator 20. The disc has a conical centre 11 and is surrounded by a retaining wall 23 so that the tablets tend to accumulate at the periphery thereof and to be shuffled into the holes 12 in which they are retained by a plate 24. A brush 21 driven by an electric motor 22 in opposition to the disc ensures that only one tablet can lodge in any hole as it approaches the transfer station. The plate 24 is formed with an aperture at the transfer station to allow the tablets to fall in succession into the holes 14 in which they are supported by a plate 28 arranged beneath the disc 13. This plate is also formed with an aperture to allow upward passage of a lifting plunger 26 which lifts each successive tablet together with a wrapper (not shown) into a wrapping wheel 27. If the quantity of tablets accumulating on the disc 10 becomes excessive, a trip arm 29 is lifted to operate a micro-switch 30 and stop the vibrator 20. The trough 18 may be replaced by a belt conveyer and a mechanically-operated finger may be provided to assist the transfer of tablets from the primary to the secondary disc.
