Title: Improvements in the feeding of collapsed cartons and the like
Inventor: ROSE ALFRED GERMAN
IPC: B65B43/18
Filed: 1956-10-09
Abstract: 846,892. Feeding sheets. ROSE BROS. (GAINSBOROUGH) Ltd. Oct. 8, 1957 [Oct. 9, 1956], No. 30691/56. Class 117. [Also in Group XVI] Collapsed cartons 11 are separated laterally from a stack by a suction head 28, assisted by a feeding member 31 which engages the rear edge of each carton and moves with the suction head to remove the carton from the stack. The suction head 28 is provided with several nozzles 29, and is adapted to be rocked about a hollow shaft 25 by means of a link 51, a lever 52 pivoted to the frame at 53, and a cam 56 which is secured on a rotating shaft 23 and acts on the lever 52. The hollow shaft 25 can also be raised and lowered by means of a link 46, a lever 47 pivoted about a fixed hollow shaft 18, and a cam 49 secured on the shaft 23. A relief valve 37, 38 on the suction head is controlled from a cam 44 on the shaft 23 through a lever 42 and link 41. The shaft 25 is carried in arms 26 pivoted about a tube 24 secured to a vertical frame 19 adapted to be rocked about the shaft 18 by a cam 22 on the shaft 23. There are several feeding members 31 carried by the suction head 28, each provided with a projection of less thickness than a carton 11. The stack of cartons is urged towards a series of stationary stop fingers 14 on a fixed shaft 16, the fingers being spaced from the mouth of the stack magazine by an amount sufficient only to allow one carton 11 at a time to be moved from the magazine. Suction is established at the nozzles 29 through a pipe 33, hollow shaft 18, a passage 34 in the frame 19, the tube 24, a passage in one arm 26, the hollow shaft 25, and ports in the suction head 28. Cartons are separated from the stack and fed to the nip of feed rollers 57 which feed them to a chain conveyer such as described in Specification 846,891. In operation, when the arm 19 is swung forward from the position shown with a carton held by the nozzles 29, the shaft 25 swings about the axis of the connection between the link 46 and arm 47, and to compensate for the resulting upward movement of the nozzles 29 away from the stack, that axis is swung towards the stack by a corresponding amount by the cam 49 acting on the arm 47. Such movement causes the arm 26 to pivot about the tube 24, and in order to maintain the faces of the nozzles 29 and the forwarding members 31 in the plane of the carton 11 during the feeding movement, the lever 52 is also actuated by the cam 56 to tilt the suction head 28 about the shaft 25. When the carton 11 is nipped between the rollers 57, the valve 37, 38 is opened by the cam 44 to cut off suction from the nozzles 29, and the cam 22 causes the frame 19 to swing back. During this movement, the cam 49 lifts the suction head 28 about the axis of the tube 24 clear of the stack, while the cam 56 rocks the suction head about the shaft 25 to move the feeding members 31 clear of the rear edge of the top carton in the stack.

Filed: 1931-11-10
Abstract: 382,434. Converting. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and CHUBB, A. A., of General Electric Co., Stoke, Coventry. Nov. 10, 1931, No. 31124. [Class 38 (ii).] Time-delay switching arrangements for limiting the anode current of a valve for a period after the switching on of cathode heating current comprise essentially a gasdischarge tube, a condenser, a resistance and an electromagnetic relay. Fig. 1 shows a full-wave mercury vapour rectifier 5 supplying anode current to the valve 14 through relay contacts 19 and the upper coil of relay 11. On switching on, the rectifier and valve cathodes are energize'd from windings 49, 50 and condenser 9 draws a small charging current through resistance 13. A glow-discharge tube 10 and the lower coil of relay 11 are connected in parallel with the condenser 9, so that when the condenser voltage reaches the striking voltage of the tube the relay is actuated, contacts 19 close and full current is drawn from the rectifier ; at the same time the condenser 9 is short-circuited by contacts 12. The modification shown in Fig. 2 is adapted for higher anode voltages, the anode current drawn from the rectifiers 28, 29 being limited by a large grid bias voltage from resistances 26, 27. The charging current for condenser 38 is derived from a potentiometer 35 through resistance 36 and when relay 41 operates by the discharge of tube 40, resistance 26 is shortcircuited by relay contacts 27. Contacts 43, 39 are simultaneously actuated, the former closing a holding circuit through the right-hand coil of relay 41 and an indicating lamp or discharge tube 42, while the latter discharges condenser 38 through resistance 37. Part of resistance 26 may be constituted by the righthand coil of relay 41.

Abstract: 324,929. Moufang, F. Nov. 1, 1928. Relay devices. - Relates to means for maintaining constant a pressure, liquid level, consistency of a fluid, specific gravity of a fluid or other characteristic, of the kind in which a jet of air impinges on a baffle the position of which is dependent on the condition to be controlled, and the resulting variations of pressure behind the jet are used to operate the relay controlling device. The invention consists in mounting the baffle so that it moves substantially at right angles to the direction of the jet. In the application to a manometer for maintaining constant the pressure of a gas, Fig. 1 the pointer 3 carries a baffle 4 which moves transversely in front of the air nozzle 5. The edge 7 normally covers half the jet opening. In the application to a liquid level-maintaining apparatus, Fig. 2, the arm 12 of a float 10 carries a baffle 13 which moves in front of the air nozzle 14, which is adjustable in the support 17. This arrangement may be used to maintain the consistency of a liquid such as paper pulp flowing through the tank 8. In the application to the regulation of the specific gravity of a liquid, Fig. 3, the liquid is supplied continuously through a pipe 20 to a vessel 19, and the stem 22 of a float 21 moves so that its upper end 24 obstructs more or less the air nozzle 25, which is formed as an annular opening in the part 26, which can be vertically adjusted on a support 27. The latter carries also a stationary pointer 29 which indicates on a scale 30 the specific gravity of the liquid at any time. The apparatus may also be employed for maintaining constant voltage or current strength, quantity of material fed, temperature, output, speed, direction and travel of a vehicle, vessel or airship, or other characteristic. Any kind of relay device may be employed, e.g., that described in Specifications 273,016, [Class 100 (i), Feeding and delivering webs &c.], and 273,602. [Class 96, Paper &c.].
