Title: Improvements in and relating to the manufacture and production of transfers and their application for the decoration of pottery, glass, enamelled iron, jewellery and the like
IPC: B44C1/175
Filed: 1928-03-16
Abstract: 317,411. Allen, L., and Deering, E. C. March 16, 1928. Transferring designs; transfers. - Pottery, glass, enamelled iron, jewellery &c. is provided with decorative designs in commercial " liquid metal " or lustre by means of transfers prepared by (1) printing the transfer paper with two or more superposed and registering impressions so as to produce sufficient body in the metal or lustre print, or (2) heating the " liquid metal " or lustre to drive off some of its volatile constituents so as to render it tacky, whereby a single impression on the transfer paper is sufficient. The transfers may also have portions of the design printed with ordinary colours but before transfer to the pottery &c. these portions are preferably coated with a film of resinous material, or alternatively, the colour for printing the coloured portions of the transfer may be mixed with a resinous material instead of with the usual oil or fatty vehicle. To effect the transfor, the pottery &c. may be slightly moistened with water, the transfer applied, and the article heated to a temperature of about 50‹ to 70‹ C. or the transfer rubbed down with a hot cloth, after which the paper is washed off. In another method, the article is heated before the transfer is applied, and in a further method the transfer is effected without heat. A transfer paper having the amount of soluble coating reduced to a minimum is preferably employed, and for use on flat surfaces, the coating may be dispensed with if a suitable surface-hardened paper is employed.

Title: Improvements in or connected with coin freed mechanism for meters
IPC: G07F15/02
Filed: 1933-03-17
Abstract: 416,100. Prepayment mechanism for meters. GLOVER & CO., Ltd., T., and WILSON, J. S., Angel Road, Edmonton, London. March 17, 1933, No. 8171. [Class 27.] Coin action, thrust, and multiple coin.- In meter prepayment mechanism for use with either of two coins, and having two quantity wheels engageable by a pivoted lever carried by a rotable coin pocket, the pivoted lever is coupled with a slide in the coin pocket by releasable means so that it engages both wheels when the smaller coin is inserted, the nearer wheel only with the larger coin, and is released from the slide so as to be inoperative with an intermediate sized coin. The coin slide 4 has an elongated slot 4<c>; the releasable means comprises a plate 10 pivoted thereto and having a pin 10<a> normally engaging a recess 7<a> in a sliding plate 7 on one side of the coin pocket. The plate 7 carries a pin 9 passing through slot 4<c>, and engaging a cam slot 5<c> in the pivoted lever 5. With the smaller coin, plates 4 and 7 are depressed together so that pin 9 moves lever 4 out to its fullest extent. With the larger coin, plate 10 is tilted by engagement with a fixed stop 12, so that slide 7 is released, and is returned by a spring 8 until pin 9 abuts against the top of slot 4<c>, the lever 4 then being in an intermediate position for engagement with one quantity wheel only. If an intermediate sized coin is inserted, plate 10 disengages slide 7, but slide 4 is not sufficiently depressed for the upper end of slot 4<c> to engage pin 9 ; consequently slide 7 and lever 4 are returned to an inoperative position.

Patent GB-628862-A (GB)
Title: Improvements in transmitting-receiving circuits for short waves
IPC: H04B1/46
Filed: 1947-03-26
Abstract: 628,862. Radio receiving systems. PHILIPS LAMPS, Ltd. March 26, 1947, No. 8236. Convention date, July 28, 1944. Addition to 623,069. [Classes 40 (v) and 40 (vi)] [Also in Group XXXVIII] In a radio transceiver circuit of the type described in the parent Specification, means are provided to change over the circuit automatically from transmission to reception, and conversely. Incoming oscillations are applied in push-pull to mixing valves 3<1> and 3<11>, and local oscillations are generated in parallel phase by these valves, as described in the parent Specification, so that an intermediate frequency output is obtained from timed circuit 12, 13. For transmitting purposes, valves 3<1> and 3<11> generate oscillations in push-pull in tuned circuit 2<1>, 2<11> which consists of Lecher lines, for transmission from aerial 1<1>, 1<11>. The push-pull oscillations for transmission are produced by means of the positive feed-back provided by inductances 14<1> and 14<11> in conjunction with the anode-grid capacities, and the parallel phase oscillations for heterodyne reception are produced by means of the positive feed-back provided by inductance 15. The parallel phase circuit consisting of impedance 5, the parallel connected impedances of both halves of the push-pull circuit and variable impedance 16 is tuned to the frequency of the local oscillations. This tuned circuit may be periodically damped under the control of diode 22 which shunts impedance 5, to prevent the production of parallel phase oscillations, the circuit then operating as a transmitter. On removal of the damping, the local oscillations are produced and the circuit operates as a superheterodyne receiver. Diode 22 is normally held non- conducting by the current through the cathode load 21 of valve 19. If a modulating signal is applied to the grid of valve 19, the valve current decreases, due to rectification effect, and diode 22 becomes conductive, thereby damping the parallel phase oscillating circuit. Instead of utilizing the modulating signal to effect the switching control, an oscillation at supersonic frequency may be applied to valve 19, to continuously switch the circuit between the states of transmission and reception. This switching frequency may also be received by the distant co-operating transmitting receiving station, where it is used to effect a corresponding switching control. The phase of this control frequency at the distant station, and also the value of the frequency at the main station, may be adjusted to allow for transit time effects and ensure effective synchronism between the co-operating transmitting and receiving periods at the two stations. The arrangement may be extended to a plurality of stations and several different switching frequencies may be used.

Title: Improved vehicle trailer
IPC: B62D53/06
Filed: 1956-03-16
Abstract: 790,888. Trailer bogie mountings. DYSON & CO., Ltd., R. A., DYSON, J., and POLLARD, T. A. F. March 16, 1956, No. 8243/56. Class 108(2) A vehicle trailer comprises a main chassis and one or more rear bogies each of which is located and held to the chassis by a removable composite rocker pin 24 consisting of a hollow sleeve, and a loose fitting operating shaft 25 having a threaded portion 25a at one end and a hand wheel 28 at the other, the sleeve 24 having 'a tapered outer surface 24c serving to align the bogie with the chassis, the threaded portion 25a co-operating with a screwed socket 22 in the bogie to pull the rocker pin 24 home so as to be a tight fit in bosses 20, 21, on the bogie and a boss 18 on the chassis. As shown, the chassis compries an upper deck 13 having a king pin 14 for connection to a tractor vehicle, and supporting a tool box 12. The lower deck 10 terminates in two frame members 15, 15, in each of which is mounted a boss 18 for the rocker pin 24 of a respective bogie. The latter comprises side frames 19, 19, formed with respective inner and outer bosses 20, 21. The pin 24 also has a medium tapered section 24e and a fine tapered section 24d. When it is desired to disconnect the bogies from the chassis, the latter is supported by jacks just forwardly of the bogies. The hand wheel 28 is then turned. and as the pin 25 unscrews from the end portion 22, a collar 26 rigid with the pin 25 engages a flange 24a of the sleeve 24, and thus effects retraction of the latter from the bosses 18, 20, and 21. Inadvertent disengagement of the rocker pin is prevented by a catch 33 operated by a spring loaded locking lever 32. The plates 19 are formed with guide plates (not shown) which.serve to locate the frame approximately in position when the bogie is run over the frame members 15 on subsequent assembly. The trailer may be provided with a ramping side edge, and may have a forecarriage instead of the king pin arrangement shown.

Title: Improvements in or relating to d.c. restoration circuits
Inventor: DAVIES ERIC
IPC: H04N5/16
Filed: 1965-02-25
Abstract: 1,086,652. D.C. restoration circuits. MARCONI CO. Ltd. Dec. 30, 1965 [Feb. 25, 1965], No. 8261/65. Heading H3T. In a D.C. restoration circuit of the type in which a semi-conductor diode D1 is associated with a resistance-capacity circuit C1, R1 having a time constant which is large with respect to one cycle of the input signal, the diode D1 is in series with an additional resistance R2 in a circuit in shunt with the resistance R 1 of the resistance-capacity circuit, and a substantially constant voltage E is applied to the junction of the diode and the additional resistance from a low-impedance source. An emitter follower T2 serves as the low-impedance source, which forward biases the diode to such a point on its characteristic that the D.C. datum voltage across R1 is not affected by variations in the charge stored on capacitor C1, which charge variations may result from variations in the amplitude or mark/space ratio of the input signals, or from extraction of energy from the noise in the input waveform. Variations in the charge on capacitor C vary the potential difference across and hence the current through and, consequently, the impedance of the diode D1. The impedance change is such as to vary the potential of the cathode of the diode in opposition to the potential change caused at that point by the charge variation of the capacitor.

Title: Method and apparatus for testing thermocouples
IPC: G01K15/00
Filed: 1975-02-28
Abstract: 1534280 Testing thermocouples SOLARTRON ELECTRONIC GROUP Ltd 27 Feb 1976 [28 Feb 1975] 8369/75 Heading G1U In a method of testing a thermocouple, firstly the resistance of the thermocouple is measured and stored at an instant when the thermocouple is known to be in good working condition, and secondly the resistance is measured later and compared with the first measurement, any deviation outside a present range indicating an abnormality in the thermocouple. The method is described embodied in a system in which a plurality of thermocouples 14, each having hot 16 and cold 18 junctions, are sequentially scanned. Each thermocouple is tested, under the control of a sequence controller 70, by first measuring its resistance when it is known to be good, this being effected by- (a) with the switches in their positions shown, measuring the output voltage of the thermocouple and storing it 40, (b) closing switches 28, 30 so as to apply a constant current 36 through the thermocouple, and (c) changing over a contact 38 so that the resulting voltage from the thermocouple when the constant current is flowing (this voltage being the sum of the thermoelectric voltage and the I-R drop across the junction) has subtracted 44 from it the first measured voltage from the thermocouple, and storing 56 the difference which represents the resistance of the thermocouple. Having established the "good" resistance of the thermocouple, at some later instant a contact 52 is changed over, a further measurement of resistance - using steps (a) and (b) above is made - and the further measurement is compared 60 with the "good" resistance, any deviation that is too large producing an output 66. To test every thermocouple in the system, one store 56 per thermocouple will be required, and either the resistance measuring section can be repeated or it can be time shared.

Cylinder 4 is also connected by at least one port in its wall to the impulse chamber of an adjustable control member by which the working chamber 8 of cylinder 1 can be separated from the pipe 38 so that the pistons 2, 4 rise until piston 4 passes the port leading to the control member, when the pressure medium acting on the control member restores the connection between cylinder 1 and pipe 38, piston 2 being restored to its original position, meanwhile forcing the hot water, drawn into the scalding chamber 9 as it rose, out through the coffee grounds or the like. Chamber 9 is separated by a sieve 10 from a detachable holder (not shown) held in a bayonet joint by claws 11. The chamber 9 is connected to the water boiler through a bore 17 and a valve 14, 15 which opens when piston 2 is raised. As shown, the wall of cylinder 3 has three ports 22, 23, 24 connected by pipes 25, 26, 27 to the three-way cock 5 whose plug 30 can be set by a hand wheel so that one of the ports is connected by pipe 31 to an impulse chamber 32 formed adjacent control cylinder 6. Between impulse chamber 32 and the space 39 of cylinder 6, an auxiliary piston 34 is displaceable in a small cylinder space 33. The cylinder space 21 of cylinder 3 is connected at the top and bottom respectively to a pipe 36 leading to the water boiler and by a pipe 37 to a pipe 38 conveying water under pressure.

Title: Improvements in or relating to rapid brake accelerators for compressed air braking systems on rail vehicles
IPC: B60T15/42
Filed: 1956-03-19
Abstract: 786,618. Fluid-pressure brakes. KNORRBREMSE GES. March 19, 1956 [March 18, 1955], No. 8532/56. Class 103 (1). An accelerator device for compressed air brakes on rail vehicles comprises a piston 15, the space 57 below which acts as a control chamber and is normally in communication by pipe 59 with an auxiliary reservoir 5 associated with a conventional triple valve 3 and brake cylinder 7. A normal drop in pressure in the brake pipe 1 communicated to the space 11 above piston 15 by pipe 13 causes the piston 15 to be moved upwards against spring 17, closing valve 45 on seat 47 and opening valve 37 so that pressure in chamber 57 may leak away through restriction 51, the movement of piston 15 being halted before it engages the push-rod 21. In the event of a substantial or emergency drop in pressure in the brake pipe 1, the piston 15 engages the rod 21 and opens valve 23, allowing a rapid local exhaust of air from the brake pipe 1 out through space 31. This construction of accelerator thus produces an intensified brake application provided the initial drop in brake pipe pressure is sufficient to cause piston 15 to engage push-rod 21.
