Title: Improvements relating to voltage regulators
Inventor: REEVES RAYMOND JOHN DENNIS
IPC: H02M3/156
Filed: 1957-10-19
Abstract: 886,101. Automatic voltage control systems. FERRANTI Ltd. Oct. 15, 1958 [Oct. 19, 1957], No. 32700/57. Class 38 (4). A direct-current voltage regulator comprises switching means interposed between an unregulated direct-current supply and a regulated output, the switching means being alternately switched on and off for time intervals which depend upon amount of variation in the supply voltage such that the average value of the output voltage is maintained at a desired value. A transistor 21 is connected between a source of direct voltage +, -, and a load R 1 , a reference voltage V o  equal to the voltage desired at the load being provided such that when the transistor 21 is conducting a saturatable reactor 23 is subjected to the voltage difference between the source voltage +, -, and the reference voltage to cause a linear rise of flux in the reactor 23 in a time integral manner until the reactor 23 becomes saturated when the current through it increases sharply to alter the bias on the base of the transistor 21 to cause it to become non- conductive. The reactor 23 is now subject to the reference voltage V 0  only and the current in the reactor 23 is now such as to desaturate it and then saturate it in the reverse direction whereupon the transistor base is once more biased so that it once more becomes conductive. The "mark-space" ratio of the ON/OFF times of the transistor depends upon the fluctuation in the supply voltage and is such that the average value of the load voltage is substantially constant. A diode 24 may be provided to prevent the base of the transistor from being driven into reverse bias. The elements L, C form a smoothing circuit and the tapping on the element L permits the transistor to be regeneratively connected. Other embodiments are described wherein the base of the transistor may be reversely biased; wherein the transistor may be forwardly biased to permit operation over a wider voltage range, wherein the charging current of the reference source is stabilized and wherein the reference voltage is derived from the regulator itself by means of a so-called " avalanche " diode.

Patent GB-328700-A (GB)
Abstract: 328,700. Tollemache, H. D. Feb. 11, 1929. Totalizators; transfer-mechanism. - The adding gear of totalizator or like apparatus is assembled by denominational units and includes step by step motors, hunting-gear and differential gearing, and transfer is effected electrically between the various denominational shafts. As shown applied to the reception of impulses pertaining to bets of 2/-, 10/-, ú1, ú10 and ú100, the impulse receivers together with the hunter and differential gears controlled by them are mounted on removable trays A', A<2>, supported in a casing A. Referring to the top tray relating to the 2/- bets, the impulse receivers are each constituted by a magnet B<1>, Fig. 6, the tapered core B<4> of which serves to rock an arm C carrying a pawl C<5> to advance a ratchet wheel D secured to a spindle D<1> carrying a contact ring D<3> and a brush D<5>. Loose on the spindle is a conducting disc E, Fig. 5, electrically connected with a main F, and engaged by the brush D<5>. When the spindle D' advances, an insulated strip E' on the disc E passes from beneath the brush D<5> so that a motor F<3> is thrown into circuit and through worm gearing rotates the disc E to re-establish the circuit break at E<1>. This rotation of the disc E is accompanied by rotation also of a shaft H<1> and these shafts are all connected up through differential gearing to drive a wheel H<2>. On the tray below is assembled similar means for summating the 10/- bets and the resulting movements transmitted through shaft J<5>, are combined with those of wheel H<2> to produce a final total of both 2/- and 10/- bets on a shaft K<3>. Similar arrangements are adopted for the other denominations up to bets of ú100 but beyond these only one impulse-receiver and motor are provided for each denomination these being for transfer purposes. When a total shaft of one denomination, say K<3> competes a revolution a contact is made at K<4> to complete a circuit to a receiver L<2> serving to enter unity in the next higher denomination. The results may be conveyed to displaying apparatus by means of transmitters S<1>, T<1> . . . , rotated under the control of the total shafts K<3>, N . . . through hunter gears S<5>. The Provisional Specification describes and illustrates a different layout for dealing with bets of 1/-, 5/-, ú1, &c. Specifications 328,594, 328,602, and 328,613 are referred to.

Patent GB-1065522-A (GB)
Title: Process for making filled polylactam articles
IPC: C08G69/18
Filed: 1963-08-20
Abstract: Filled polylactam material is obtained by wetting a finely divided filler with a surfactant and a non-aqueous carrier liquid, mixing the wetted filler with a lactam containing at least 6 carbon atoms in the ring, and polymerizing the lactam by anionic polymerization at a temperature between the m.p. of the monomer and that of the polymer. Examples of lactams are e -capro-, enanthro-, caprylo-, decano-, undecano-, dodecano-, pentadecano-, and hexadecano-lactams, methyl cyclohexanone isoximes, and cyclic hexamethylene adipimide. Suitable surfactants are 3,5-dimethyl-1-hexyn3-ol, octyl phenoxy polyethoxy ethanol, nonyl-phenol-ethylene oxide, alkyl-aryl hydrocarbons, tallow dimethyl benzyl ammonium chloride, organic phosphate esters, polyoxypropylene or polyoxyethylene.  The liquid carrier may be (a) a low boiling lactam soluble liquid, e.g. kerosene, toluene, alcohols or ketones, (b) a plasticizer, e.g. chlorinated biphenyls or N-methyl-2-pyrollidone, or (c) the lactam itself. Polymerization is effected by heating at between the melting point of the monomer and 250 DEG  C. in the presence of 0.01-20 mole per cent each of a catalyst and initiator.  The catalyst may be an alkali or alkaline earth metal or its hydride or lactam salt, borohydride, oxide, hydroxide, carbonate or organometal derivative, or an organo Mg or Al compound.  The initiator may be an organic isocyanate, ketone, acid chloride or anhydride or N-substituted imide.  These materials are added to the filler together with the lactam, or alternatively the salt formed by reacting the catalyst with the lactam may be employed. Articles may be cast simultaneously with polymerization. In examples MoS2, boron, and a blue pigment are used as fillers, sodium hydride and PLMgBr as catalysts, and tolylene diisocyanate as initiator.

Title: Improvements in automatic refrigerator controls
IPC: F25D21/00
Filed: 1953-11-30
Abstract: 740,523. Thermal switches; actuation of switches. GENERAL ELECTRIC CO. Nov. 30, 1953 [Nov. 29, 1952], No. 33236/53. Class 38(5) [Also in Group XIII] A control switch for a refrigerator hav ing a compressor motor 14 and a defrost heater 48, comprises a thermally movable member 5 controlling the motor and a member 23 for controlling the heater, the second member 23 being actuated by timing means which is energized only when the refrigerator door is open and the motor is operating, the timing means closing the heater circuit after a predetermined cumulative amount of time, The member 5 forms part of a thermal switch and actuates contacts 11. The member 23 is a lever pivoted at 26 and engaging a toggle spring 35 which biases it to either of its end positions. The lever has an insulating extension 45 extending between a spring blade 56 and its bent-over contact-carrying end, so that in one position of lever 23 contacts 50, 53 are open, as shown, and in the other position, the contacts are closed. The timing means comprises a motor 72 which drives a gear train 80, 81, 82, 85, the gear 85 carrying a pin 90, co-operable with a pin 92 projecting from one side of a freely pivoted disc 87. The pin 92 is extended at 91 on the other face of the disc and is connected by a spring 96 with the casing 22. Normally contacts 50, 53 are open and the spring is contracted, the disc 87 being in a ration 180 degrees from the Fig. 1 position. When gear 85 is rotated, pin 90 eventually engages pin 92 and disc 87 is also rotated, thereby stretching spring 96 until the Fig. 1 position is reached. A slight further movement of gear 85 then moves spring 96 from the dead-centre position and disc 87 is snapped through the next 180 degrees. During this snap movement, the pin 91 engages the underside of a part 98 secured to insulating extension 45 and forces the lever 23 and spring 35 across a dead-centre position to close contacts 50. 53 with a snap action to close the heater circuit. This movement is passed to member 5 through a rod 66 and switch 11 is thereby opened to stop the motor 14. When the refrigerator is heated to a certain temperature, e.g. 55‹F, determined by the adjustment of spring 35 by a screw 42 the switch 11 is opened thermally and the rod 66 is forced down to open contacts 50, 53 and the normal operation is resumed. As shown in Fig. 5 the timing motor 72 is connected in series with door-operated contacts 74 and is connected to the supply via contacts 11, so that contacts 11 and 74 must be closed to energize motor 72. The total accumulative time of closure of contacts 72 to effect defrosting may be 6“ minutes.

Abstract: 1,046,437. Mines &c. O. WEISS. Aug. 22, 1963 [July 1, 1963], No. 33319/63. Heading E1F. Mineral deposits in the earth are detected by taking samples of airborne particles and analysing the samples to determine the existence of a deposit. The size and quality of particles of a particular mineral tend to be larger in the samples taken directly over a deposit of the mineral. The method is suitable for detecting deposits under dry land surfaces which are not covered with snow, ice or dense vegetation. Air currents may be induced above the surface being surveyed by burning vegetation, exploding charges, the rotors of low flying helicopters, fans suspended from aircraft, or tubes for blowing compressed air suspended from aircraft. The apparatus for sampling includes a filter membrane which is carried by aircraft, helicopters, balloons or rockets. As a sample is taken the position of the vehicle is determined photographically or by radar.. The membrane may be coated with reagent chemicals giving an indication of the presence of particular minerals, or it may be examined by X-rays, to avoid analysing all samples. The membranes having particles to be analysed are treated with a solvent capable of dissolving the membrane but not the particles, and the resultant solution iscentrifuged to concentrate the particles which are finally analysed for identity and size by an electron probe analyser.
