Title: Improvements in prepayment apparatus
IPC: G07F5/10
Filed: 1937-01-01
Abstract: 481,632. Delivery of electricity by time-controlled prepayment apparatus. DURAND, J. VULLIET-. Jan. 1, 1937, No. 39. [Class 27] In prepayment apparatus for controlling the supply of electricity on a time basis, a ratchet wheel 11 is advanced one step clockwise for each coin inserted, and closes contacts 13 and 13<1> in the supply circuit and the circuit of a synchronous motor M. At the same time a pin 14 on the ratchet wheel is advanced away from a pin 15 on a coaxial disc 16 by an amount proportionate to the prepayment. The motor M drives the shaft 5 of the disc 16 through reduction gearing, causing the pin 15 to follow the pin 14, until ultimately, at the expiration of the prepaid period, the pin 15 engages the pin 14 and turns the ratchet wheel 11 a short distance to cut off the supply and the motor M. The ratchet wheel operates the contact spring 13 through an intermediate blade 20<1>. A blade 20 serves to locate the ratchet wheel correctly in its contact closing position. Coin action, thrust ; fraud, preventing.-A coin is passed down an insertion shoot 2 by inserting the fingers through side apertures 2<1>, and acts through the previously inserted, coin, which is held in the position shown by spring plungers 38 and 39, on an arm 9<1> of a threearmed lever 9, turning it anticlockwise. On the return clockwise movement of the threearmed lever 9 under the action of a spring 19, a pin 35 on a rod 8 connected with a second arm of the lever advances the ratchet wheel 11 through one tooth. A spring plunger 37<1> prevents withdrawal of the coin after insertion. Exhibiting coins after insertion ; indicators.- The previously inserted coin is visible, whilst in the position shown, through an inspection opening. If a previous coin is not present, the apparatus cannot be used and the spring plunger 39 closes electrical contacts to operate an audible or visible signal. A pointer 31 on the disc 16 indicates against numerals on the ratchet wheel 11 the extent of the prepaid period. Registering.-The third arm 9<111> of the lever 9 operates a spring 401 to step up a counter 46 at each coin insertion.

Filed: 1936-01-01
Abstract: 468,289. Modulating systems. FROST, F. G., and STERLINGWORKS (DAGENHAM), Ltd. Jan. 1, 1936, No. 75. [Class 40 (v)] Modulation is effected by varying the absorption produced by tuned circuits coupled to the oscillation generator, by altering by means of modulating potentials, the conductivity of oppositely-disposed rectifiers included in the absorption circuits. An inductance 1 Fig. 1, is coupled to oscillator A, and connected through opposed rectifiers 2, 3, to the acceptor circuit comprising inductance 5 and condensers 4, 6. Tappings 12, 11, on inductances 1, 5 are joined. Modulating potentials from 10 are applied via transformer 9 and high-frequency chokes 7, 8 to the rectifiers. With no modulation applied, alternate half cycles of high-frequency current flow round each half of the circuit comprising inductances 1; 5, condensers 4 or 6, and rectifiers 2 or 3, and the absorption is a maximum. When the rectifiers are biassed alternately by modulating potentials the oscillations are modulated by the varying absorption. In a modification, Fig. 2 (not shown), the taps 11, 12 and their connecting lead are omitted. With this arrangement, the absorption with no modulation is a minimum.

Title: Distillation of calcium or magnesium
Inventor: BARTON JAMES
IPC: C22B26/20
Filed: 1947-01-03
Abstract: 720,261. Distilling metals; calcium, magnesium, alkali metals. LORD PRESIDENT OF THE COUNCIL. Jan. 5, 1948 [Jan. 3, 1947], No. 316/47. Class 82 (1). Calcium or magnesium containing as impurity alkali metal other than lithium are purified by distilling in two stages, in the first of which distillation is carried out in the presence of an inert gas at an absolute pressure substantially greater than the vapour pressure of calcium or magnesium at the temperature of distillation but less than the vapour pressure at that temperature of the said alkali metal so that the alkali metal is distilled and condensed on a surface, the second stage being carried out in the absence of inert gas so that the calcium or magnesium distils under its own vapour pressure only and condenses on a lower condensing surface. The Figure shows a stainless steel vessel 1 containing crude calcium or magnesium 2, the vessel being immersed in a molten salt bath 3. Cover 5 carries a hollow cylinder 6 with water-cooled flange 9 and internal fins 8, which assist in cooling the condenser surface, and a plate 7 on which the calcium or magnesium is to be condensed. Between the plate 7 and the wall of the vessel is an annular space through which alkali metal vapour rises to condense on the cooled flange 9. Cooling of the condensing surfaces is effected by air or other cooling medium from duct 11 passing over the fins 8. Duct 12 connects the interior of the vessel with vacuum pump, pressure gauge and inert gas supply. A perforated plate 17 controls the radiation of heat to the condenser. A suitable plate is one having 3000-4000 perforations of “ inch diameter occupying 15-25 per cent of the total plate area. In operation the salt bath is heated to about 870‹ C. and alkali metal distils in an argon atmosphere at a pressure of about 20 mm. mercury condensing on the cooled flange 9 maintained at a temperature of about 250‹ C. The first stage is completed when the lower condensing surface shows a sudden drop in temperature. The still is then evacuated and calcium or magnesium distils and condenses on the plate 7 which attains, with calcium, a temperature of about 400‹ C. A rapid drop of this temperature indicates the completion of distillation. Specifications 270,060, [Class 82 (1)], and 698,861 are referred to.
