Title: Improvements relating to coin-operated change giving machines
IPC: G07F5/24
Filed: 1935-10-18
Abstract: 464,685. Coin-operated change-giving apparatus. SCHNEIDER, R., and WESTINGHOUSE TICKET MACHINE CO., Ltd. Oct. 18, 1935, No. 28871. [Class 27] In a coin-operated change-giving machine in which a number of coins are delivered as change for a coin inserted into the machine with or without the delivery of an article, such as a railway ticket, the change coins are ejected from the coin storage receptacle 21 in a single operation or as a bunch by one of a number of arms 15 pivotally carried on a continuously rotating disc 11. Each arm has a pin or roller 17 engaging a fixed cam slot 18 which maintains it in a radial inward position against the action of a spring 16. When an arm is allowed to move outwards by a portion 19 of the cam slot, the end 20 of the arm moves through the lower portion of the receptacle 21 and ejects a number of coins as change. The number of coins ejected is determined by adjusting the receptacle 21 vertically in a support 23 by a screwthreaded sleeve 24, an indicator 25 being provided to show the number of coins to be ejected and the position of the receptacle 21. Normally the arms are prevented from moving to ejecting position by the curved end 38 of a lever 8 which is held in obstructing position, until a coin has been inserted, by a latch 7. The inserted coin passing down a shoot 3, 4 moves aside a lever 5, which, by an arm 6, releases the latch 7. The lever 8 is then moved by a spring 9 to allow an ejecting arm 15 to move outwards. A rod 10 depending from the lever 8 effects the operation of ticket-delivery mechanism. Cams 13 on the disc 11 engage an arm 14 on the lever 8 to return this to position where it is again locked by the latch 7. Indicators ; returning coin.-The issuing pile of change raises a pivoted ratchet-toothed member 29 to an extent dependent on the number of coins in the pile, this number being indicated on a scale 32 connected to the member 29 which is held in its raised position against the action of a return spring 30 by a pawl 31. This pawl is connected to the lever 5 and is released by the coin dropping down the shoot 4. The member 29 is connected by a link 36 with a pin-and-slot connection to a lever 34 controlled by a spring 35 tending to move a stop 33 on the top of the lever into the coin shoot 4. If there is insufficient change in the tube 21, the link 36 does not hold the stop 33 out of the shoot 4 and the next coin inserted is diverted and returned. The coin for which insufficient change was given, is retained by a pin 39 on the lower end of the lever 34.

Title: Improvements in or relating to resonant aerials
IPC: H01Q5/15
Filed: 1946-10-01
Abstract: 628,987. Aerials. CORK, E. C. Oct. 1, 1946, No. 29183. [Class 40 (vii)] An aerial resonant in two or more frequency bands comprises a conductor series loaded by reactive elements including an inductance shunted by a capacity, said elements being disposed along the conductor so that the distances between them are always short compared with the operating wavelength and being of such magnitude that the same length of conductor is effective and resonant in each band. The Figure shows a portion of an aerial 10 interrupted by loading elements 11 comprising inductors 12 with capacitors 13 in parallel with at least a portion thereof. Values of components and the aerial length are chosen so that in the lower frequency band the aerial is inductively loaded and resonant while in the higher frequency band it is capacitively loaded and resonant. If the capacitors 13 are shunted across only part of the inductors, a series tuned circuit is formed at a third frequency, whereby the aerial is effectively unloaded and if the natural length is suitably chosen the aerial is then resonant at this third frequency. It is pointed out that the elements 11 may also approach infinite impedance at a further frequency, so splitting the aerial into a string of individual elements.

Title: Improvements in process of transferring vitamines
IPC: A23L33/15
Filed: 1927-11-02
Abstract: 280,212. Gronning saeter, S., and Fischer-Hollinshed Co., Inc. Nov. 2, 1926, [Convention date]. Medicines for internal use. - Vitamins are transferred from substances containing them to a desired substance by first forming a solution of the vitamin, and adding the desired substance and a diluent to cause the vitamin to leave the solution and become absorbed in the desired substance. The invention is described with reference to the transfer of fat-soluble vitamin from oils such as cod-liver oil to other oils deficient in vitamin, such as cotton-seed oil. The cod-liver oil is saponified with alkali hydroxide in presence of an organic solvent such as alcohol, and the cotton-seed oil is added together with water. After thorough mixing, the mass is allowed to stand until it separates into layers, when the cottonseed oil is drawn off and washed. It may be treated with steam to remove flavouring substances, and is suitable for medical use. Other oils such as butter, egg-oil, &c. may be used instead of cod-liver oil, and other oils such as vegetable, animal or mineral oils may be used instead of cotton-seed oil. Other solvents such as benzine, ether, &c. may be used instead of alcohol. When an excess of alkali is employed for the saponification, it is preferably neutralized, for instance with sodium bicarbonate, before adding the cotton-seed oil or the like.

Title: Improvements in or relating to processes of manufacturing highly active carbon, and in the products thereby obtained
IPC: C01B32/384
Filed: 1924-12-06
Abstract: 239,744. BrÚgeat, J. H. Dec. 6, 1024. Drawings to Specification. Carbon.-Active carbon in the form of pieces of special shape is produced by impregnating charcoal dust from wood or similar cellulosic material with alkali silicate solution or a solution containing a salt of aluminium or iron and a binder such as casein or gums, moulding or drawing out the paste so formed to the desired shape and then precipitating the absorbed alkali silicate by means of hydrochloric acid or the metallic salt by means of alkali, washing the charcoal free from the soluble salt and finally calcining in a closed vessel between 600 and 1000‹ C. In alternative processes the binder such as casein &c. may be used with the solution of alkali silicate and the treatment with acid may be performed after the calcination. The latter may also precede the washing. According to an example, wood charcoal dust is mixed with a solution containing sodium silicate and gum arabic to form a paste. The latter is converted into small hollow cylinders having a plurality of internal axial passages or channels in their exterior surface and after drying in the open air these are steeped in hydrochloric acid solution. The pieces are washed with water and dried in a closed vessel between 600 and 1000‹ C. In a second example, a paste formed from a mixture of charcoal dust with silicate of soda is moulded into the shape of spherical grains having lenticular cavities. The grains are treated with hydrochloric acid dried and calcined as before. The cooled charcoal is finally washed and dried. In a third example, wood charcoal dust is mixed with perchloride of iron solution containing thick gum arabic. The paste is drawn out into the form of small tubes which may be grooved axially both internally and externally and then dried, first in the open air and then at 100‹ C. After calcining at 800‹ C. the cooled charcoal is treated with ammonia, washed and dried. Alternatively, the charcoal may be treated with ammonia before the calcination.
