Title: Process for obtaining proofs in relief of photographs or pictures by embossing or stamping
IPC: G03F7/00
Filed: 1930-03-31
Abstract: 351,109. Relief pictures. SERAPHIM, J., 58, Rue de Paris, Asnieres, Seine, France. March 31, 1930, No. 10213. Convention date, Aug. 6, 1929. [Class 11.] A process for obtaining proofs in relief of photographs or pictures by embossing or stamping consists in giving the desired relief to the original proof by means of a spatula, chisel, or the like, and from this proof taking a casting in plaster, modelling clay, &c., and making therefrom a matrix and a die which are used for embossing replica proofs and metal backings. The replica proof 1 is attached by adhesive to a cardboard backing 6, with the embossed metal backing 4 intervening. The proof and its metal backing may be embossed either together or separately. An elastic pad may be used in place of the die.
Patent GB-807991-A (GB)
Title: Improvements in and relating to means for controlling or regulating the feed of materials
Inventor: CRIDDLE LINDEN GLEN
IPC: H02P5/46
Filed: 1954-04-07
Abstract: 807,991. Automatic control systems. INDUSTRIAL MACHINERY CO. Ltd. April 6, 1955 [April 7, 1954], No. 10242/54. Class 38 (4). In an electrical system for automatically controlling a property of fed material, a signal is fed back in opposition to the error signal for a time which is controlled by the charge and discharge of a condenser and which approximately equals the interval between correction of feed and detection of the correction. In Fig. 2 the feed of tobacco from an agitating hopper 20 on to a conveyer 21 is controlled by a reversible synchronous electric motor 24 adjusting the degree of opening of hopper outlet 22. The tobacco is formed into a road and cut into cigarettes at 27 and a detector 28 produces a voltage, dependent in magnitude and polarity on deviation in density of the tobacco in the cigarettes from a desired value, which is applied to a thermionic valve 31 so as to operate a polarized two-way and off relay 33 and thereby cause motor 24 to run in the appropriate direction to correct the deviation automatically. Simultaneously with the operation of relay 33 one or other of relays 34, 35 is operated to apply a voltage to a condenser 51 which charges up with the appropriate polarity to restore relay 33 to its off position by control of a thermionic valve 32. The time constant of the charging circuit of condenser 51 is chosen so that motor 24 runs initially for a period equal to the delay between application of correction and detection of such correction by detector 28. When relay 33 moves to its off position, a discharge circuit for condenser 51 is established having a time constant such that the current through valve 32 alters at the same rate during discharge of the condenser as the current through valve 31 alters in consequence of the feed correction. In a modification the feed correcting motor operates a potentiometer arranged in a bridge circuit the output of which is fed back to the relay control circuit through a condenser so that the feedback disappears after the required period. There are references to radiation, dielectric and weighing-type detectors, to controlling size, colour or weight, and to control of textiles, plastic or paper. Specifications 558,491 and 744,311, [Group XXXVI], are referred to.

Title: Improvements in and connected with electric motors
IPC: H02P7/06
Filed: 1925-04-20
Abstract: 251,095. Midgley, A. H. April 20, 1925. Motors, controlling.-A resistance wire is wound around the field-magnet coil of an electric motor, for example, a small motor operating an oscillatory wind-screen wiper on a. motor vehicle, so that when the resistance is switched into circuit for reducing the speed, additional magnetizing turns are applied to the field. Fig. 2 shows the connections in the case of a series motor. When the switch s connects with the contact x, the motor runs at its normal speed, but when the switch is moved over on to contact z, the resistance r is placed in series with the field coil c and armature m, and the motor runs at reduced speed. Fig. 3 shows the connections for a. shunt motor, the resistance in this case being in series with the armature only. Intermediate speeds may be obtained by bringing out tappings from the resistance to additional switch contacts.

Title: Improvements in power-driven rafts for surf riding and other purposes
IPC: B63B1/12
Filed: 1958-04-01
Abstract: 871,057. Power driven rafts. HUGHES, P. N. July 30, 1958 [April 1, 1958], No. 10375/58. Classes 113 and 114. A power driven raft for surf-riding comprises a frame made up of two longitudinal members 1, adjustable in length, with cross-bars 2 and 3 at the fore and aft ends respectively. A rider supporting platform 13 is slung between the longitudinals 1 and a power propulsion unit 7 is mounted on the cross-bar 2, and supplementary crossbar 6, which carries a propeller 10 via the shaft enclosed in the tube 9. The raft is rendered steerable by an arrangement allowing the propellor shaft to be rotatable about its own axis. Connected at each end of the cross-bar 2 are floats 5, and another float 4 is mounted at the centre of the cross-bar 3, which maintain the raft at least partly submerged under the weight of a rider. The two floats 5 may be replaced by a single float spanning the width of the framework at the fore end. The propulsion unit 7 may be mounted at the rear end and remotely controlled from the fore end. The floats 4 and 5 may be replaced by wheels driven by the power unit 7. To minimise air or water drag behind the floats 4 and 5 they may be provided with a fin arrangement. On each side of the float 4 or 5 a fin lying in a general vertical position, but curved to the configuration of the float wall, is spaced away from the wall. This forms a longitudinal airway or waterway between the float and fin, and the latter may be provided with a line or lines of perforations, slits or the like extending longitudinally therealong.

Abstract: 234,791. Askania-Werke Akt.-Ges. vorm. Centralwerkstatt-Dessau und C. Bamberg-Friedenau. May 31, 1924, [Convention date]. Gaseous-fuel furnaces. -In natural-draught gasfired furnaces, more particularly of large size such as blast-furnace boilers, Cowper apparatus &c., the gas pressure at the inlet is maintained at atmospheric pressure. For this purpose the gas at an inlet point corresponding with the open air inlet b is controlled by a baffle d in combination with differential pressure measuring or regulating devices of known type and acts on a diaphragm or piston connected with a valve e in the supply pipe, so as to maintain the desired pressure value. The gas and air mixture is thus always of con. stant proportions and the rate of combustion is determined solely by the chimney damper. Where several furnaces are connected in parallel, a gas main with a, single pressure regulator is employed and appropriate equalizing resistances are inserted in the branch pipes.
