Filed: 1952-10-22
Abstract: 756,663. Electricity meters. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Oct. 22, 1953 [Oct. 22, 1952; Jan. 2, 1953], Nos. 26550/52 and 184/53. Class 37. [Also in Groups VIII and XIX] Recording-apparatus for an electricity meter (see Group XIX) may be associated with switching arrangements to disconnect the electricity supply during recording. In one arrangement, Fig. 1, a switch 38 in the main supply circuit is opened by an arm 41 fast with the knob 25 when it is rocked to effect recording. Alternatively, a normally-open switch, closed while the knob is in effective position, may be arranged in series with a heater associated with a thermal switch which, if the knob 25 is held in operative position, breaks the main supply circuit. As a further alternative, Fig. 5, the knob 25 may normally be disengaged from its shaft by an electromagnetically-operated clutch 61 which is de-energized only when a main switch is opened. The latter switch may be controlled by the knob.

IPC: B01F15/02
Filed: 1949-10-17
Abstract: 667,226. Mixing in definite proportions. SIMON (HOLDINGS), Ltd., H. Sept. 27, 1950 [Oct. 17, 1949], No. 26565/49. Class 86 In a machine for mixing solid materials with added fluids, the added fluids are delivered by a piston-type pump, the piston rod of which is coupled to a variable-stroke reciprocating feeder for solid material by means which are adjustable to allow of the alteration of the effective stroke of the pump as compared with the stroke of the reciprocating feeder, whereby the relative quantity of fluid to solid material can be pre-set according to requirements. The preparation of provender compounds is particularly referred to. In the apparatus described, a variable-stroke reciprocating feeder 6, which supplies solid material to a mixer 1, is coupled by linkage 7 to 10 to a link 11 which is pivoted to a piston rod 12 which carries pistons in pump cylinders 21 for supplying fluids to the mixer. The link 11 is slotted at 13 to receive pmot pins 14 carried by a slide 15 which is adjustable by a screw 16 and handwheel 17 whereby the stroke imparted by the link 11 to the piston rod 12 can be varied. The total quantity of material fed to the mixer depends upon the length of stroke of the feeder 6 as adjusted by the linkage 4. Specification 638,305, [Group XXX], is referred to.

Title: Improvements relating to electric discharge lamp circuits
Inventor: FARMER WALTER JOHN RENAUD
IPC: H05B41/282
Filed: 1961-07-24
Abstract: 937,577. Supply systems for discharge lamps. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 23, 1962 [July 24, 1961], No. 26722/61. Class 38 (4). To prevent operation of a discharge lamp 1 (due to excess supply voltage) before its electrodes 2, 3 have been sufficiently heated, a resistor 15 whose resistance varies inversely with its temperature is connected in series with the secondary winding 7 of the supply transformer 4, a capacitor 14 being connected across this series combination. Upon energization of the primary winding 5 the high resistance of the resistor 15 prevents initiation of the lamp discharge which would normally occur if the supply voltage was high. However passage of current through the circuit comprising members 7, 14, 15 heats up the resistor 15 and lowers its resistance, thus allowing the discharge to commence at a predetermined time after transformer energization. The capacitor 14 may be placed by a heater wire located adjacent the resistor 15. The ballast choke 11 may be generally similar to that of Specification 927,188. Alternatively the lamp discharge may be stabilized by using a supply transformer similar to that of Specification 847,417. The transformer 4 is supplied from a conventional oscillator 6 driven from a D.C. source 10.

Title: Improvements in or relating to a circuit arrangement for rhythmic signalling systems, for example a telegraph system
IPC: H04L7/033
Filed: 1963-07-05
Abstract: 995,053. Telegraphy. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. July 5, 1963 [July 10, 1962], No. 26750/63. Heading H4P. The invention provides a rhythmic telegraph receiver in which the time base which scans the received signals is synchronized on the signals. The time base provides a pulse train in which the leading edge of each pulse is in sync. with the bit transitions in the received signal. The trailing edge of the pulse is automatically adjusted to one or other of two time positions dependent upon the relative phase of the transitions and the leading edges, to prevent synchronization on that edge. Frequency shift signals received over a radio channel 1 are converted to D.C. Mark and Space signals by F1, F2. Differentiator 21 derives a pulse at each bit transition, and units 4-9 provide a clean signal for operation of printer 10: the received signals are centre scanned by gates 7, 8. The time base comprises units 11-13. Unit 11 provides ten pulses during each bit received, the pulses passing via a phase corrector 12 to decimal counter 13 which gives a 4 m.sec. pulse /t4, t5) to gates 7, 8, 22, 29; and 8 m.sec. pulses (t0-t3) and (t6-t9) to open gates 17, 18, respectively. A transition pulse during t0-t3 passes gates 17, 25 to reversible counter 16 to be counted in one direction, whereas a pulse during t6-t9 passes gates 18, 26 to be counted in the other direction. Whenever counter 16 is full in either direction it provides a phase correction pulse to unit 12 which causes the omission or intercalation, as appropriate, of a pulse in the pulse train fed to counter 13. Thus the counter sampling pulse t4-t5 is maintained at the approximate mid-point of each bit of a series of received signals. If a transition pulse arrives during t4-t5 it passes via gate 29 and gate 30 or 31 dependent upon the state of bistable unit 32. This unit is set by the outputs of gates 17, 18. Hence, if the previous transition was during t0-t3, the present transition acts on counter 16 as though it too arrived during this period. The result is that the receiver cannot synchronize itself in such a way that the transition pulses lie in the periods t4-t5.

Title: Improvements in or relating to the production of mouldable articles from lignin derivative material and fibrous filler
IPC: C08L1/02
Filed: 1936-10-06
Abstract: 482,894. Fibrous boards &c. MEAD CORPORATION. Oct. 6, 1936, No. 27139. Convention date, Oct. 25, 1935. [Class 96] Mouldable articles are produced by mixing intimately with agitation, fibrous material in water with finely divided lignin derivative material obtained from digestion liquor used in the preparation of paper pulp, flowing the mixture containing, e.g. 97 per cent of water on to a former and withdrawing water, e.g. by suction to form a sheet or other article which is pressed to desired form and thickness and dried at a temperature below the fixing temperature of the lignin derivative material. Finely-divided, substantially-pure, ash-free, lignin residues are obtained from sulphite, sulphate, soda &c. digestion of woody materials, as by precipitation by an acid such as carbon dioxide in the case of a black liquor from a soda cask. The fibrous material may be cotton linters, alpha-cellulose, ground wood, asbestos or pyrophillite. The lignin residues are precipitated at pH=7À8 to 9 and the suspension heated to about 60‹ C. to coagulate the particles cooled, filtered, washed, treated with excess acid, e.g. sulphuric, again washed. The dried material may be granulated. It may be used with phenol-formaldehyde or urea-formaldehyde resins, pigments, e.g. carbon or nubian black, dyes &c., alum &c. being added during or after beating. Size may be added to the pulp in the usual way. The boards &c. are dried at low temperature compacted at, e.g. 10,000 lb. per square inch and moulded at 310 to 350‹F. Furfurol may be added to control the fusing temperature of the lignin derivative. The board may be surfaced with material of superior quality applied before final moulding, embossing, &c. The moulded board may be used for automobile bodies.

Title: Improvements in or relating to magnetic amplifiers
IPC: H03F9/06
Filed: 1959-08-12
Abstract: 873,593. Magnetic amplifiers. WESTING- HOUSE ELECTRIC CORPORATION. Aug. 12, 1959 [Aug. 22, 1958], No. 27541/59. Class 40 (9). An amplifier is constructed from a single winding 32 on a core 31, the winding being energized in one direction over rectifier 34 during one half-cycle from a first A.C. source and being energized in the other direction during a next half-cycle of a second A.C. source in antiphase with the first source. During a halfcycle in which rectifier 34 conducts, i.e. an output half-cycle, secondary winding 70 of power supply transformer 60 supplies a positive voltage to rectifier 34 while the opposite ends of secondary winding 80 supply positive voltage to close an input gating rectifier 23, and negative voltage to open an output gating rectifier 43. When the core 31 fires, rectifier 43 blocks and an output appears at terminal 50. During the next half-cycle, i.e. an input half-cycle, gating rectifier 23 is opened by negative voltage from winding 80 to an extent determined by an input voltage on terminal 10, and gating rectifier 43 is blocked by positive voltage over resistor 42 which finds a path over rectifier 36, the upper part of winding 32, rectifier 35, and over the forwardly conducting gating rectifier 23 to earth, and in so doing resets the core 31 in so far as forward conduction in 23 is permitted by the input. Since the output of the amplifier, assuming maximum input signal and in consequence no reset, is delayed for the initial part of an output halfcycle by an amount necessary to switch the core from romance to saturation and to provide charge for rectifiers, the reset half-wave in an input half-cycle is delayed by the addition of saturable reactors 90, 91, in the connections between secondary winding 80 and the amplifier. This is necessary to prevent cumulative error in a cascade connection of amplifiers alternate stages of which would be supplied at terminal 41 from reactor 90 or reactor 91. Resistors 92, 93 provide a path for magnetizing current in the reactors 90, 91, while rectifiers 101, 102 transfer earth from tap 82, to tap 85 of winding 80 during alternate half-cycles, thereby providing a larger negative voltage to block the input and output gating rectifiers 23 and 43.
