Title: Improvements in track circuits for railways
IPC: B61L1/18
Filed: 1935-09-11
Abstract: 445,515. Railway signalling systems. GENERAL RAILWAY SIGNAL CO., Rochester, New York, U.S.A.-(Assignees of Rees, F. X. ; 37, Bancker Street, Albany, New York, U.S.A.) Sept. 11, 1935, No. 25291. Convention date, May 29. [Class 105] A direct-current relay R at one end of a track section is energized by time-spaced unidirectional voltage pulses applied at the other end of the section and having a peak value materially greater than the rated voltage of the relay. An automatic compensation for variation in the ballast resistance is thus obtained since with increased ballast resistance the inter-rail voltage rises (by reason of the smaller drop in the limiting resistance) to give a higher peak value to the relay current but on account of the higher decay rate of the current between the pulses, due to the higher ballast resistance, the mean current remains approximately constant. A resistance or reactance 3 is inserted in series with the track relay R and the higher voltage thus required serves to break down the film resistance of the wheel shunt. The voltage pulses may be obtained by inserting a copper-oxide type half-wave rectifier 5 in series with the secondary of a track-circuit feed transformer 4. Such rectifier has an effective resistance value which increases with decreasing current and thus further aids in the automatic compensation. The current decay rate, and therefore the average current can be adjusted by placing a resistance 7 across the rails at the feed end. The time-spaced voltage impulses may be given by a battery over a back contact of a vibrating relay.

Title: Manufacture of imitation linen in the form of towels, handkerchiefs, serviettes, table cloths, sheets, swaddling cloths and similar fabric articles
IPC: D21H17/66
Filed: 1929-08-20
Abstract: 338,224. Munktell, E. O. Aug. 20, 1929. Compound sheet materials.-Imitation linen, towels, handkerchiefs, serviettes, table cloths, sheets, swaddling clothes, &c. are made by pressing superposed layers consisting wholly or mainly of cellulose wadding of which some layers are sized or impregnated more strongly than others and some may be free from size or impregnation. Normally goffering is effected simultaneously with or subsequent to the pressing, but sized &c. layers which have previously been goffered may be used, the material preferably being sized in a hollander before formation of the lavers. The cellulose wadding may be replaced wholly or in part by Yoshino or Japanese paper &c. In practice, cellulose is ground in a hollander until it becomes slimy or smeary and is then formed into wadding. A number of superposed layers of wadding, with or without layers of paper or strengthening layers of cotton wool, pass close to a device where the impregnating agent is sprayed upon them in a fine mist by nozzles such as are used in Duco-lacquering. Alternatively the impregnation may be effected by coating, dipping or pressing. A pair of goffered or plain rollers then press the layers together and when the pressing and goffering are complete, the material is dried on one or more cloth covered drying cylinders. To keep the layers better together, the edges of one layer may be folded over one or more adjacent layers. Suitable impregnating agents are nitro-cellulose, acetyl-cellulose, gelatine, glue, &c., or paraffin oil or wax if a waxlike surface is desired. Alternatively, a mixture of water, starch, borax, Japan wax, casein, blanc fixe, gelatine, glue, resin glue and casein with or without hardening or softening agents may be used. For increasing the strength of any layer, colloidal solutions of rubber &c. may be used. Specifications 252,719 and 252,720 are referred to.

Title: Improvements in methods of and means for applying closures to containers
IPC: B67B3/14
Filed: 1939-09-09
Abstract: 532,595. Capping bottles. THORNTON, A. A. (Thermoplastic Bottle Sealing Corporation). Sept. 9, 1939, No. 25498. [Class 125 (ii)] A bottle closure consists of a disc D of thermoplastic material and a smaller disc D<SP>1</SP> of stiff fibrous material with a serrated circumference. The centre of the disc D and the disc D' are forced down on to a shoulder b<SP>1</SP> in the bottle neck, and the rest of the disc D expanded against the bottle neck and folded over the outside to form a skirt as shown in Fig. 30. A holder 52 for the small discs D' is arranged above a slideway 51 and a holder 43 for the large discs D beneath the slideway 51. A slide P, P' with two convex faces 60, 60' feeds one large disc and one small disc D, D' concentrically arranged to an electric heating chamber 54, whence they are fed by another slide P" into position above the bottle C and beneath the sealing head 91. The slide P" is operated directly by the hand lever 67 and the slide P, P<SP>1</SP> indirectly through a lever 66 with a spring end 64. At the end of the feeding stroke of the slide P, P' the end 64 is moved out of action and the slide is returned by springs not shown. An adhesive may be applied to the underside of the lowest disc in the holder 52 by a dabber connected at 29 to the lever 67. The sealing head 91 is depressed by a lever 94 and treadle 93. First the discs D, D' are forced down on to the shoulder b' in the bottle neck, then the flattening of the flexed spring plate 109 and the radially moving shoes 111 cause the material of the disc D to be expanded to contact with the interior of the bottle neck, and finally the outer edge of the disc D is rolled into a skirt down the outside of the bottle neck by rollers 115 carried on spring-pressed levers 116 mounted on the parts 98, 118 of the head 91 which still descends against the action of the spring 96' after the central part of the head has been arrested. The lowering of the head causes a delayed indicator bell I to ring after an interval long enough to allow the thermoplastic disc D to set. In the modification shown in Fig. 35 the disc D is expanded within the bottle neck by pivoted shoes 111e when they engage the top of the bottle.

Title: Improvements in or relating to ice cream portioning and dispensing devices
IPC: A23G/
Filed: 1963-06-27
Abstract: 976,068. Delivering measured quantities of liquid. APAW S.A. June 27, 1963 [June 27, 1962], No. 25685/63. Heading B8N.  A device for dispensing measured quantities of ice-cream comprises a cylinder 1 having inlet and outlet ports 4, 3, a measuring piston and slidably guided and adapted to move, via a friction coupling 9, together with a dispensing piston 5 arranged to open or close the inlet port, the measuring piston co-operating with an abutment upon a return movement of the piston 5 in order to define a measuring chamber 201, and means 10, 102 for connecting the measuring chamber with the outlet port. The measuring piston 8 is connected to a rod 71 on which is carried a removable stop member 73 and, formed with projection 10 which, in the position shown in Fig. 1, maintains a clearance space in order to provide communication between the measuring chamber and the outlet. In operation, the dispensing piston is raised to the position shown in Fig. 3 wherein the piston 8 abuts a shoulder and the piston 5 continues until it uncovers the inlet port 4. Pressurized ice-cream is then fed into the inlet thereby forcing the measuring piston downwardly to a position limited by the stop 73. The dispensing piston 5 is then forced downwardly until the projections 10 of the piston 8 abut on end plate 2, thus allowing the ice-cream to be forced through the outlet. In the modification shown in Fig. 8 for admitting a syrup into the ice-cream as the latter is dispensed, the rod 7 is provided with a bore 307 having ports 12 controlled by a valve member 13 and the piston 5 is formed with ports 14 which co-operate with a syrup inlet port 15. In the position shown in Fig. 8, ice-cream is fed into the port 4 as previously explained and, at the same time, syrup is fed, via ports 14, 15, into a chamber 16. Upon downward movement of the piston 5, the valve member 13 uncovers the ports 12 thereby allowing the syrup to be dispensed through the port 307 together with the ice-cream. In a further modification, the slide valve 13 may be replaced by a ball valve.

Title: Improvements in or relating to the starting of synchronous motors for television apparatus and the like
IPC: H04N5/04
Filed: 1931-09-15
Abstract: 376,088. Control of motors. FERNSEH AKT.-GES., Goerz-Allee, Zehlendorf, Berlin. Sept. 15, 1931, No. 25830. Convention date, Sept. 15, 1930. [Class 38 (iii).] With auxiliary starting motor.-A synchronous motor of the inductor type for television receiving apparatus is started by means of a starting motor, and the synchronous motor is automatically supplied with current when synchronous speed is attained or nearly attained, by means acting co-initially with the switching- on of the starting motor. When the starting motor, which may be overloaded during starting, has brought the synchronous motor up to speed, it may be decoupled, switched off by lifting its brushes, or its terminal voltage may be reduced so that it runs weakly loaded. If the synchronous motor is supplied from a thermionic valve, the time taken for the valve to get warm may be used to delay the flow of current to the synchronous motor. Alternatively a time-lag relay, which may be thermally operated, may be used. An additional timelag relay may be provided to switch off, or reduce the current to the starting motor, after synchronous speed has been attained for a certain time, or a simple hand-switch may be used for this purpose.
