Title: Time directed pneumatic tube conveyor system
IPC: B65G51/40
Filed: 1941-03-17
Abstract: 546,486. Pneumatic conveyers. HAMERSCHLAG, G. March 17, 1941, No. 3603. [Class 78 (i)] A pneumatic tube conveyer system in which the despatch apparatus at the central station includes, for each despatch tube serving a group of sub-stations, a plurality of terminal fittings 9 corresponding each to a sub-station, each fitting being adapted to receive and retain carriers ready for despatch, has means for automatically releasing the carriers for entry into the despatch tube 1 in pre-determined succession. In the form shown the carrier when inserted in the fitting 9 rests on a pivoted projection 16 and presses inward a spring biased pivoted lever 22 which thus allows contacts 26; 27 to touch. A circuit through battery 47, earth, and a relay 37 is by this means completed and three switches 34, 35, 36 are closed. One side of each of these switches is connected respectively to discs 30, 31 and 32 mounted on a common shaft 28 rotated at constant speed, through brushes 41, 42, 43 bearing on the discs. The rims of the discs are made up partly of non-conducting portions and in part of conductors 38, 39,40, connected each electrically to the shaft 28 and battery 47. Making of the switch 34 maintains current through the relay 37, after the carrier has dropped and allowed switch 26, 27 to open, for nearly a full revolution of the shaft 28. Making of switch 35 retracts momentarily the projection 16 by means of a solenoid 50, so allowing the carrier to fall. Making of switch 36 excites a solenoid 52 which shunts over a track flap 14 at the particular sub-station and also opens. the valve in the branch tube 10. In the case of the furthest sub-station. no flap 14 is provided, and the solenoid 52 acts directly on the air valve. All groups of discs 30, 31, 32 may be mounted on one shaft 28, both for the sub-stations of any one route, and for all routes. Alternatively each disc may carry a plurality of conductors to function successively in the required order. The " sending " sub-stations may be connected by long branches to the main return route pipe, which is preferably of the suction type.

Title: A metal casting plant
IPC: B22D17/30
Filed: 1966-01-28
Abstract: 1,134,861. Metal pouring. WIENER SCHWACHSTROMWERKE G.m.b.H. 28 Jan., 1966 [28 Jan., 1965], No. 3875/66. Heading B3F. A casting plant in which predetermined quantities of molten metal are delivered from a furnace to a pressure casting machine comprises an induction furnace 1 with interconnected chambers 2 and 3, the chambers being provided with covers 6 and 5 respectively and are pressurized from a source 12 to deliver molten metal via pipe 13 and trough 14 into a shot well 15 of a pressure casting machine. A sensing device located in a predetermined position in the well 15 controls, through an electric circuit, the operation of the valves 11 and 16 in the pressure line so that the quantity of molten metal supplied from the furnace is controlled by the volume of metal in the shot well 15, the sending device being withdrawn from the shot well at the commencement of each injection stroke of the plunger 17. Various alternative forms of sensing devices may be used such as a float or an electrode contact. Further control means is provided to compensate for the residue of molten metal passing through the feed trough 14 when the furnace chambers are depressurized since this quantity enters the shot well 15 of the casting machine. Any variation of the quantity of this metal residue necessitates a change in the length of the stroke of the injection plunger if a constant volume is to be supplied to the die cavity by the plunger. A cam 21 is therefore attached to the plunger shaft, which depending on the position of the plunger operates a variable resistance 23 incorporated in electrical means for generating time pulses corresponding to the change in the length of stroke of the plunger and which controls the rotation of a motor 25. A cam rotated by the motor controls the operation of a valve member 30 which varies the opening in the pipe 13, thus controlling the flow of molten metal to the shot well 15. A multi-position programme switch controls the electrical supply to the motor and to the timer. Alternative control circuits are described and include time control means operating a valve (38), Fig. 6 (not shown) in the pressure line which compensates for electrodynamic pressures set up during the operation of the furnace and a control circuit may be provided which functions in relation to the metal bath level in furnace, Fig. 7 (not shown), and on a time basis or a circuit may be provided which incorporates a single timer controlling all the different control actions.

Abstract: 465,375. Two-part couplings. SANDERS & CO. (WEDNESBURY), Ltd., and PRESTON, W. Feb. 10, 1936, No. 3964. [Class 38 (i)] The insertion of an earth-pin into a switch plug of the type in which an arm is displaced by the earth pin to uncover the current-carrying socket tubes, is prevented by a catch engaging the arm when the switch is " on." Projecting into the earth-pin socket 11, is an arm 14, pivoted on lugs 13, and displaced by the earthpin to move a spring-controlled cover 15 from over the current-carrying socket tubes 10.. A collar 16, pivoting about the socket 11, has a catch 22 which locks with the arm 14, and is urged into this position by a spring 19 fastened to a projection 20 on the collar and to a screw 17 working in a slot 18. When in the " off " position, a projection 9 on the switch 8 engages a projection 21 on the collar 16 so that the plug member may be inserted. When the switch is " on," the projection 9 leaves the projection 21, rotating the collar, if possible, and locking the arm 14. If the plug member is in engagement with the socket, then upon the withdrawal of the member, the cover 15 is urged by the spring 23 to cover the sockets 10, the catch locking the arm 14.

Title: Improvements in or relating to thermostatic timing devices for controlling electric circuits
IPC: H01H50/86
Filed: 1931-02-11
Abstract: 372,799. Valve circuits. GENERAL ELECTRIC CO., Ltd. and PETERS, W. H., Telephone Works, Stoke, Coventry. Feb. 11, 1931, No. 4227. [Class 40 (v).] A combined relay and thermostat is employed in circuits using heated cathode rectifiers so that on switching on, the thermostat causes the relay to operate after a predetermined interval, actuation of the relay causing increased current to be drawn from the rectifier. Fig. 1 shows an electromagnetic relay 2, 3, combined with a thermal switch consisting of a bimetallic strip 11 heated by a resistance coil 6 and a spring contact 10. An application of the device is shown in Fig. 2, the relay coil 2 being included in the cathode return circuit of an output valve 12 supplied with anode current from a rectifier 14. On switching on, the amplifier 12 draws a small anode current, since its grid is negatively biased by coil 2 and heater resistance 6. The small current through 6 causes contacts 4, 5 to close after a certain interval, thereby short-circuiting 6 which restores normal bias to the grid of 12. The increased anode current through 2 actuates the relay thus keeping contacts 4, 5 closed. A loud-speaker high voltage field may be connected as shown in dotted lines.
