Title: Machine for Making, Filling and Closing Packaging Containers.
IPC: B65B43/10
Filed: 1968-02-01
Abstract: 1,157,594. Making containers. FR. HESSER MASCHINENFABKIK-A.G. 1 Feb., 1968 [20 Feb., 1967], No. 5112/68. Heading B5D. [Also in Division B8] A machine for forming, filling and closing containers, comprises at least two wheels, intermittently rotatable in vertical planes and equipped with a number of shaping mandrels. Containers formed on the mandrels are transferred to receivers in a continuously moving horizontal conveyer by means of intermediate conveyers. Filling and closing devices are arranged in the path of the horizontal conveyer. Containers P are formed on mandrels 3 from a web 16. The mandrels are mounted on two wheels 2 driven by a common shaft 1. The web 16 is fed by rollers 14, 15 on to horizontal supports 13, and is severed by a knife 18. A plate 10 holds the severed blank against the mandrel, and as the wheel rotates, the sides of the blank are folded up by the two parts of the support 13. A die 12 seams the blank, and a known device 19, e.g. as described in U.S.A. Specification 2,677,223, forms a bottom closure which is consolidated by dies 20. A second group of folding &c., devices (not shown), may form an outer container on top of the first one. Also, the devices may rotate in a direction opposite to the wheel. The formed containers are transferred, e.g. by an air jet, from the mandrels into pockets 5 of transfer plates 4 which rotate intermittently on inclined shafts 21 so that the containers are vertical when they arrive above the horizontal conveyer 6. Air from nozzles 22 now blows the containers into holders 23 in the conveyer 6. The pockets 5 may be rotatable to orientate the containers. Devices 7 and 8, of known form, fill and close the containers, and the completed packages are discharged on to a belt 24. The material fed into the containers may be of a measured weight. The filling and closing devices may be as described in U.S.A. Specifications 2,942,761 and 2,729,928 respectively.

Abstract: 1,168,734. Reciprocating pumps. HARDMAN Inc. Feb.6, 1967, No. 5624/67. Heading F1A. A pump for metering liquids or pastes comprises two pistons 18, 20 reciprocable in tandem in a bore 12, piston 18 being driven directly by a cam 32 through slide 24, and piston 20 through rod 36 and friction blocks 40 on slide 38, a fixed stop 54 and an adjustable stop 56 limiting the strokes of piston 20. On the leftward stroke, piston 20 stops adjacent an inlet port 14 and piston 18 moves away from piston 20 to draw liquid into bore 12. The pistons then both move to the right until stop 54 stops piston 20 and piston 18 moves towards piston 20 to discharge the liquid through an outlet 16, the setting of stop 56 determining the quantity drawn in on each stroke. Friction blocks 40 are split longitudinally and spring-loaded, Fig. 1a (not shown), to grip rod 36 so that the rod slips through the blocks when stops 54 and 56 are engaged. In Fig. 6 (not shown), three pumps are driven by a common electric motor through a belt drive incorporating a split pulley to adjust the speed and a solenoid-controlled clutch, which can be operated to give one or more pumps strokes according to the setting of an electrical circuit controlled by a foot switch, a band switch and a cam-actuated switch on the pump cam shaft. The adjustable stops 56 of the pumps are adjusted simultaneously and in required proportion by common adjusting means. The pumps draw from separate sources and deliver to a mixing chamber incorporating an agitator energized by the pump control circuit. In Fig. 8, (not shown), friction blocks 40 are replaced by an electromagnet which is energized to transmit drive from rod 36 to piston 20, a fixed switch and an adjustable switch replacing stops 54 and 56 and, together with a switch operated by a cam on cam 32, controlling energization of the electromagnet.

Abstract: 1468311 Gas turbine plant LINDE AG 13 Feb 1975 [16 Feb 1974] 6208/75 Heading F1G, F1Q [Also in Division F4] The invention relates to a process for the recovery of energy from a liquified gas by the evaporation thereof in heat exchange with a circulating fluid which is thereby cooled; the cooled fluid is subsequently compressed, heated and expanded so as to produce power; the lowest temperature of the circulating fluid in the system is such that the fluid remains in the gaseous state. In the Figure liquefied natural gas is supplied through line 1 and pump 2 to a heat exchanger 3, the LNG being heated and vaporized by fluid such as air or helium forming the working fluid of a closed cycle gas turbine plant, the air being thereby cooled. The cooled air is then compressed in compressor 5, preheated in heat exchanger 6, further heated in heater 7 then expanded in turbine 8 which drives the compressor also a load 9. The air then passes through a heat exchanger 13 then through the heat exchanger 6 being thereby cooled, then through the heat exchanger 3 where it is further cooled, being then returned to the compressor. The LNG after being vaporized in the heat exchanger 3 is further heated in heat exchanger 10 then in the heat exchanger 13, being then utilized as the working fluid in turbine 12. The gas discharging from the turbine 12 is utilized as the heating fluid in the heat exchanger 10, finally passing to a point.
