Title: Improvements in and relating to plants for the stacking of sheet metal
IPC: B65H29/32
Filed: 1960-07-19
Abstract: 903,624. Stacking metal sheets. UNGERER, F. July 19, 1960 [Jan. 29, 1960; March 22, 1960], No. 25113/60. Addition to 888,350. Class 100 (1). [Also in Group XXX] A plant for the stacking of sheet metal in accordance with the parent Specification is modified in that the suction heads 7-11 are capable of being connected by a throw-over valve 52 alternatively to a source 54 of suction and to a source 56 of pressure at least equal to that of the ambient atmosphere and are controllable by a device containing an impulse generator, a delayed-action relay 44 and a control member 46 therefor connected to the throwover valve, the time lag of the delayed-action relay being adjustable. In the schematic circuit of Fig. 3, a radiation receiver 42 is shown connected to a control device 45 which is connected both to the delayed-action relay 44 and to a timing relay 51, each of which relays is connected to an actuating member 50 for the valve 52. The radiation receiver is mounted above the lower run of the perforated conveyer 3 and a radiation emitter 43 is mounted below the lower run of the conveyer. The relay 44 is manually adjustable through the control member 46 so as to accommodate variations in the length and weight of the sheets being stacked, and is automatically adjustable by means of a governor 48 driven from the conveyer 3 to accommodate variations in the speed of the conveyer. The relay 51 is adjustable manually. In operation, the leading edge of a sheet 16 picked up by the conveyer 3 intercepts the radiation beam from the emitter 43 and this causes the radiation receiver 42 to emit an impulse, which is, however, suppressed by the control device 45. When the trailing edge of the sheet passes over the emitter 43 the receiver 42 emits a second impulse which is transmitted by the control device 45 to the delayed-action relay 44. After an appropriate interval, determined by the adjustment of the relay 44, the latter relay operates the actuating member 50 and the member 50 actuates the valve 52 so as to disconnect the heads 7-11 from the suction source 54 and connect them to the pressure source 56 whereby the sheet is deposited on a table 18 of the type described in the parent Specification. The second impulse from the receiver 42 is also transmitted to the timing relay 51 which, after an appropriate delay to allow the sheet to fall clear of the conveyer, operates the actuating member 50 a second time so that suction is applied to the heads 7-11 once again. The governor 48 may be replaced by a revolution counter or a speedometer.

Title: Container filling apparatus and method
Inventor: FRIENDSHIP KENNETH FRANCIS MON
IPC: B67C7/00
Filed: 1960-07-21
Abstract: 952,988. Bottling; filling casks. BURNETT & ROLFE Ltd. Sept. 29, 1961 [July 21, 1960], No. 25515/60. Heading B8T. [Also in Division F2] A method of sterilizing and then filling a container e.g. a cask with liquid includes the steps of passing steam into the container and allowing the steam escaping therefrom to act on a detecting device which acts, on detecting a predetermined temperature corresponding to the sterilization of the container by the steam, to shut off the steam supply, to cause the container to be cooled, and to apply a gas to the container to replace the steam and thus provide a counter pressure, and a timing device being then arranged to cause a liquid to fill the container, there being provision to automatically stop liquid delivery when the container is full. The apparatus of Fig. 1 includes a steam conduit 1, carbon dioxide conduit 2, a liquid, e.g. beer, conduit 3 with a pump 12 extending from a tank 13, and a cooling water conduit 20 supplying a sprayer 22. Conduits 5 and 7 lead to an adapter 27 which fits the opening of a container 25 to be filled. A conduit 6 leads to the top of the tank, and a conduit 4 has a thermostat 14, steam trap 15 and a steam outlet 16. The conduit valves A-F are electropneumatically operated via electromagnetic relays, and initially the valves A and D are opened and steam from a source 10 passes into the container and condensed steam therefrom flows through the conduit 4 and steam trap 15 to atmosphere. As the temperature of the escaping steam rises, a bellows in the steam trap closes the outflow therefrom and the thermostat 14 operates the relay &c. system so that the steam valve A is closed; a timing device is also energized and valves B and F opened so that CO 2  passes into the container and water is sprayed over it. At a predetermined time after the operation of the thermmostat the valves B and F are closed and valves C and E opened; valve D is closed before the opening of valve C. When the container is full some of the liquid extends into a device 70 which houses a pair of spaced electrodes whereby the difference in electrical resistance therebetween is altered so operating a relay closing all the valves A-F. Sterilizing agent may be passed through the conduits 2, 3, 5, 6 and 7 after the opening of valves B, C and E. In a modification the conduit 2 and valve B are dispensed with, the gas at the top of the tank providing the counter pressure. The conduit 6 may be connected to a pair of receivers for foam which reforms into beer, which is forced to a sterilizer as described in Specification 924,173 the beer then passing to the tank 13.
