Inventor: WHITE GEORGE
IPC: A23G3/28
Filed: 1915-07-22
Abstract: 100,914. White, G., Baker, G. S., and Baker, G. R. July 22, 1915 Coating confectioners' goods.-To produce any desired chocolate or icing design on confectionery, a receptacle containing the chocolate &c. is suspended above the confectionery and is given a universal motion verticallv to start the flow of the chocolate and laterally and longitudinally to produce the .design. The confectionery to be decorated may be brought by a conveyer 57 beneath the jacketed vessel 118 containing the chocolate. At the lower end of this vessel are grooved rollers 119, scrapers 120, and an outlet or a series of outlets 120<a> for discharging the chocolate. The vessel is carried by a chain 121 from one arm of a lever 122, the other arm 125 of which receives motion from a cam 126 on a shaft 127. At each end of the vessel, an arm 130 is fixed, its other end being supported by a ball-and-socket bearing 131 allowing the desired vertical movement to take place. The ball of each bearing is connected by a rod 132 to two ball-and-socket devices, the middle ball 140 passing freely through the rod, and its socket being connected by a rocking lever 141 to a sleeve 142 carrying a lever 142a having a roller 143, which is actuated by a cam 129 on a shaft 127, and thereby producing a longitudinal reciprocating movement of the vessel 118, the upper bearings 133 acting as fulcra. The lateral movement of the vessel is obtained by connecting the upper sockets 133 to a rectangular bar 135 which receives movement by means of a link 136, an arm 137, and a roller 139 in contact with another cam 128, the middle bearings acting as fulcra to allow this movement. A spring 135<a> causes the return of the bar 135. The cams 128, 129 are changed as a unit when desired to produce a different pattern. The machine is driven from a main shaft 153 through gearing 172, 145, belt 146, and stop-motion gearing 143<a>, 144, while the rollers are rotated by gearing 147<a>, 147, 148, 149, flexible shaft 150, and gearing 151, 152.

Abstract: 541,629. Thermionic valves. BRITISH THOMSON-HOUSTON CO., Ltd. May 31, 1940, No. 9548. Convention date, May 31, 1939. [Class 39 (i)] In high-frequency power valves, the cathode consists of a number of filaments 13, arranged in parallel around a cylinder. They are secured at their upper ends to fixed supporting leads 33, which are spaced in insulating discs 35, 36. The lower ends are secured to lugs 42 on a disc 41. A rod 44 secured to the disc 41, moves freely in the discs 35, 36 and is acted on by a compression spring bearing on a stop piece 46 to maintain the filaments in tension. A housing formed in two parts 49, 50 encloses the spring and the two parts are designed to abut when the spring is compressed to a degree representing the tension of the filaments in the cold state. The invention is described in connection with a valve, the envelope of which is formed by the anode to which is sealed a glass part carrying re-entrant press for the cathode leads. A base cap, carrying the terminals, consisting of a disc of insulating material is secured to the envelope by an angle ring cemented in position. The Specification as open to inspection under Sect. 91 describes also a mount for the grid. This subject-matter does not appear in the Specification as accepted, but is described in Specification 541,645.

Abstract: 1,142,001. Electric selective signalling. ELECTRIC & MUSICAL INDUSTRIES Ltd. 7 March, 1966 [6 March, 1965], No. 9615/65. Heading G4H. [Also in Division H4] In a system for positioning a vehicle such as a crane a conductor 1 is laid along the track of the vehicle and a plurality of equal resistances 5 are connected from respective tapping points on the conductor 1 to a common bus-bar 6. A source 2 producing A.C. at, say, 2000c/s, is connected to the bus-bar 6 and also supplies via an adjustable tap 7 on an auto-transformer 8 each end of the conductor 1. The auto-transformer 8 is effectively short-circuited and divides the current flow in the two directions into the required proportions i 1  and i 2  and at one tapping e.g. A, on conductor 1, as determined by the adjustment of tap 7, the currents i 1  and i 2  will be equal and opposite. Pick-up coils 3 and 4 carried by the vehicle compare the phase of the signal from conductor 1 with that from bus-bar 6 which is independent of the position of the vehicle and the resulting signal is used to cause the vehicle to move to point A. In addition, as the signal induced in coil 3 becomes smaller as the point A is approached, the speed of the vehicle may be controlled by the signal from coil 3 so that it slows down as it approaches the required position. In order to minimize the effects of cable resistance, conductors 6 or 1 may be divided into a number of sections, the required section being selected by a multipoint switch, Figs. 3 and 4 (not shown). Alternatively, Fig. 5 (not shown), the currents (i 1 , i 2 ) are caused to flow diagonally across the network of resistors (5) to supply the current to the end resistors by means of transformers (13, 14) or Fig. 6 (not shown), the current through the central resistor (5) is caused to be the mean value of the currents through the end resistors by means of transformer coupling. It is stated that the resistors may be replaced by transformers connected in a tree circuit in which the final junction point is connected via the source (2) to the tap (7).

[Class 35] In a magneto having a rotary cylindrical magnet with field blocks of spiked form forming poles which act on the armature poles, the field blocks include solid magnetic members clamped against the ends of the magnet and of cylindrical external form to receive laminated flux distributers which are mounted on cylindrical rows of the blocks, the inner peripheries of the rims not being in contact with the magnet. In the form shown, the field blocks 3 are clamped, by a nut 6 and a flange 5 on the shaft, against the ends of the magnet 4 and taper inwardly at their cylindrical outer surfaces on which are mounted the flux distributers 8 in the form of rings having integral polar projections. These projections co-operate with pairs of similarly laminated armature poles 13, 14 cast into the frame and joined in pairs on both sides of the armature coil 21 by laminated bridges 19. The magnetic circuit is completed by the laminated armature core 22 at right-angles to the shaft. The various sets of laminae are secured together by insulated rivets and the armature assembly is secured by screws 23 passing through the core 22 and bridges 19 into the frame. Paper or other insulating sheet is inserted between the bridges and poles 8 or between the bridges and core 22, in which case the bridge plates are slit to preclude closed circuits around the core. The form shown has four polar projections on each ring 8, the two rings being displaced by 45 degrees from polar coincidence.
