Title: Method of, and apparatus for manufacturing filling, and sealing liquid-tight containers
IPC: B65B7/18
Filed: 1963-06-04
Abstract: 1,028,636. Making liquid containers; reciprocating conveyers. JAGENBERK - WERKE A.G. June 4, 1963 [June 22, 1962], No. 22138/63. Headings B8A, B8C and B8P. Erecting, filling and sealing containers.-A machine for filling liquid tight containers erects the containers from flattened tubular blanks 18 (Fig. 10), forms a bellows-closure at the bottom of each container, fills the container and forms a further bellows-closure at the top. In the machine illustrated a swingable folding pocket assembly 21 erects the tubular blanks 18 which are pushed stepwise along a stationary slide 22 by fingers 25 on a reciprocating member 24, which member is swung about a shaft 23 clear of the slide 22 during its return stroke. At station II, Fig. 14 (not shown), a vertically reciprocable mandrel 26 is inserted in the container body and the bottom bellows-shaped closure is formed by jaws 28, and the preliminary breaking of the upper closure is effected by arms 27. The depending portion of the closure then passes through a heating stage (station III), and a pressure stage (station IV) where a laterally movable jaw 31 (Fig. 16, not shown) presses the closure against a fixed jaw 32 provided with an internal passage for a coolant. At a further stage (station V), a component 34, having a groove 33 in which the depending portion slides, is moved laterally to the direction of movement of the container body, thus folding the depending portion to form a flat container base. A vertically reciprocable press ram 35 further compresses the folded closure against an elastic anvil 36 (Fig. 18, not shown). The container is filled with milk at station VI from a nozzle 38 lowered into the container, and further movement of the container introduces the partially broken upper closure into a plough which unites the two opposed sides of the closure. Sealing is effected by heat and pressure as described in connection with the bottom closure. A plurality of conveyers arranged in parallel may be used and the closure means may be driven by a common drive. Forming the flattened tubular container bodies.- Prescored blanks (Fig. 1) coated with plastics on at least one side are conveyed by a continuous motion through a machine which folds them about the score line 3 and welds the edges 15, 15<SP>1</SP> together to form a flat tube with a web seam. A further web seam is formed by welding the strap bounded by the lines 2, 3 to the panel 8. The flattened tubes may then be stacked for transport.

Title: Automatic plastic sealed valves
IPC: F16K3/36
Filed: 1956-07-26
Abstract: 813,191. Valves. BUTLER, G. A. July 26, 1956 [Aug. 29, 1955], No. 23182/56. Class 135. A valve having a gate 22 has at least one removable reservoir 29 or 30 disposed in a chamber 12 formed by the valve body and the valve bonnet 53, the reservoir lying adjacent to a valve seat 15 or 16 and a passage 90 connecting it with a passage 27 or 28 in the seat. The reservoirs contain pistons 36 below which is a lubricating and sealing plastic. The two reservoirs 29, 30, shown, may be formed from lengths of pipe or may be otherwise constructed to have an elongated cylindrical shape fitting tightly into conical recesses 32, 33 in the valve body. Reservoirs 29, 30 of different sizes may be provided for the same valve, according to the use to which it is to be put. The tops of the reservoirs 29, 30 are open to the chamber 12. When the valve gate 22 closes the fluid flow line 11, the high pressure on one side of the gate, e.g. the right-hand side of the Figure, forces the gate against the seat 15 on the lowpressure side and allows some fluid under pressure to leak past the seat 16 on the other side of the gate into the chamber 12. The pressure thus induced in the chamber 12 acts downwardly upon the tops of the pistons 36 in the reservoirs 29, 30. Since the pressure in the groove 28 of the valve seat 16 of the sealing plastic is opposed by the same pressure of the fluid leaking past it, no sealing plastic is extruded by movement of the piston. On the down-stream side of the gate 22, no equal fluid pressure opposes flow of the sealing plastic to the groove 27 in the seat 15, and accordingly the piston 36 moves downward in the reservoir 29 until sealing has been completed. Additional sealing plastic can be introduced into the reservoir 29, 30 through screw-closed bores, Fig. 2 (not shown). The chamber 12 is closed by a bonnet 53 carrying a pair of stops 44 which can engage the top of the pistons 36 and prevent their being forced out of the reservoirs 29, 30. The bonnet 53 is secured to the body of the valve by a resilient sealing ring 56, a snap-ring 59 and screws in a collar 60. In a modification, Fig. 4 (not shown), the stops 44, 45 are of a relatively short length and are made integral with the valve bonnet. Specification 700,848 is referred to.

Title: Electric wave impulse generators
IPC: H03K7/00
Filed: 1944-11-22
Abstract: 590,495. Generating H.F. oscillations; pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. Nov. 22,1944, No. 23260. Convention date, Feb. 25, 1942. [Class 40 (v)] Short electric wave-impulses of high energy are generated by arranging a D.C. circuit to be interrupted electro-mechanically under the control of signal currents so as to shock-excite a substantially closed hollow resonator from which the generated wave impulses are derived. As shown, the interrupter comprises a vibrating rod 32, mounted in a vessel 30 evacuated or filled with an inert gas, and operated by an electromagnet 13 to open normally closed contacts 31, 36, in a circuit energized by a D.C. source 14 and including a tank circuit formed by a hollow resonator 25 which at each opening of the switch is shock excited. Since the switch contacts interrupt substantially without arcing, very high power, wave trains are induced in the tank, circuit and may be radiated from antenna 18 or transmitted to any other load circuit. Preferably, the magnet 13 is energized by time-modulated pulses derived, e.g. as described in Specification 511,222, from a time modulator 22 supplied with signals from source 21 for modulating impulses from generator 20. The rod 32 is, in this case, damped so that it is capable of following the time modulation. The load antenna 18 is coupled by a coaxial line 28 and loop 27. The enclosed switch 30 is attached directly to a portion of the walls of the resonant chamber so that the latter forms in part an envelope for the enclosed switch. The upper contact of the vibrating switch member is substantially in line with one of the walls of chamber 25 to which the fixed switch contact 36 is directly connected. Alternatively, contact 36 may be made integral with the chamber 25. The battery 14 is preferably connected to the chamber 25 at a plurality of points over lines 24 to secure adequate current distribution. In a modification, Fig. 3 (not shown), the glass switch envelope 30, instead of being sealed to a metal member forming part of chamber 25 as in Fig. 2, merely extends into the chamber.
