Title: Method of and apparatus for making valve bags
Inventor: GERBER KENNETH GEORGE
IPC: B31B19/84
Filed: 1960-03-03
Abstract: 944,425. Valve bags. METAL BOX CO. Ltd. Feb. 17, 1961 [March 3, 1960], No. 7577/60. Heading B5D. [Also in Division B8] In a method of making valve bags from thermoplastics material a multiple valve unit consisting of a series of valve members is interposed between longitudinal edge portions of a V folded bag body-forming web and secured by the transverse heat seals. The valve members include side seams 9 and mouth strips F which remain free to assist opening for filling which takes place through an aperture 23 of the valve exit 11. In one form of apparatus a tubular web 1 is fed from one of two rolls 26 through smoothing rollers 27, splicer 28, used to splice the web ends when a roll is exhausted, past knives 5 which slit the tube at 7 to form two V-folded webs. One web 13 is passed round pins 29, 30, so that it is horizontally offset from the other wider web 14. The webs then pass, through intermittently rotatable rollers 3, round dance rollers 31, 32, and through tension rolls 33 and nip rolls 34 to a press 35 where cutters and heaters form an undulating heat seal between the two layers of the web 13 and sever a waste portion 12. The portion 12 is removed by rolls 37, 38. The remainder of the web 13 is then fed back above the press past a guillotine 36, which cuts off peaks 10 of the undulations, over guide rollers 39, 40 and around a guide pin 16 so as to be fed between the longitudinal edges of the body forming web 14, the web 14 being opened by a peg 22. Seal resistant elements 21 are inserted through the valve mouths and heat sealers mounted on the press 35 form the bag side seams 19, 20 and end seals adjacent the inlet 23. The webs 13, 14 are drawn through the press by means of a reciprocating slide 45 carrying grippers 41-44. In another embodiment (Fig. 1) the tubular web 1 is moved continuously through the machine. It is split at 6, 7 by knives 4, 5 to form a V folded web 14 and two superimposed webs 13. The webs 13 are sealed together by undulating heat seals 9 and waste portions 12 are removed. The remaining portion of the webs 13 which forms the valve unit is passed round pins 16, 17 so as to be inserted in the V folded web 14. Seal resistant elements 21 are inserted through the bag mouths and side seams 19 are formed, these operations being carried out by members which move with the webs while operating. The chain of bags produced may be cut into single bags by cutter 25 or means may be provided to perforate the bags along each heat seal 19 and either a pair of tearing rollers which separate the individual bags from the web be provided or the perforated chain may be rolled or fan-folded for storage until required for use. As a further alternative the method may be carried out manually. Also in any of the above embodiments a pair of overlying webs may be used instead of a tube, a bag bottom forming seal being made in this case.

Abstract: 817,983. Steam irons. COMPAGNIE FRANCAISE THOMSON-HOUSTON March 8, 1957 [March 8, 1956], No. 7768/57. Class 138 (2). An electric steam iron has a drop-by-drop water feed system disposed inside but separable from a water reservoir, the system forming an assembly which is applied solely by pressure against a seating in the reservoir and is maintained in position by securing means which can be released to allow removal of the assembly from the reservoir. As shown in Fig. 1 the feed system comprises a tube 1 which is attached to the handle 16 by a tube 5, through which water is supplied to the reservoir 6 by way of holes 1<SP>1</SP> in the tube 1 and 9<SP>1</SP> in reinforcing cylinder 9. Tube 1 is attached to a member 2 containing an orifice 6b communicating with the vaporization chamber, the flow through the orifice being controlled by valve 3. Member 2 seats on a gasket 17, made of a material capable of withstanding a temperature of about 250 C., which seals the gap between member 2 and member 14 which itself is welded to the base of the reservoir and is screwed within hut 13 which is welded to the vaporization chamber cover.

A solenoid 20 through which the rod is slidable is flanked by a pair of plungers 17, 18 fixed to the rod and carrying conical spring washers 19. As the rod is moved leftwardly the spring 19 on the plunger 18 engages and displaces the solenoid until, on increased loading on the rod as the cones 13, 14 engage, the sensor 23 energizes the solenoid through a controller 24 causing the solenoid to become anchored in a ferromagnetic, e.g. mild steel, sleeve 15 and the plunger 18 to be drawn leftwardly, compressing the spring 19. On completion of synchronization the solenoid is deenergized and the synchronizer is positively engaged by the final part of the movement of the lever 11. The plunger 17 is operative on another synchronizer (not shown) actuated by rightward movement of the rod. The load sensor 23 may alternately be in the lever 11. Also, the lever 11 may incorporate means for disengaging a transmission clutch when it is grasped by the driver.

Abstract: 1306531 Fluid-pressure servomotor systems. INTERNATIONAL BASIC ECONOMY CORP 19 Feb 1970 [19 Feb 1969] 8070/70 Heading G3P An unloading valve 26 for a hydraulic system is opened to connect a pump 10 to a reservoir 12 when a high-pressure valve 32 is actuated and is closed to connect the pump to an accumulator 14 through a check valve 16 when a low pressure valve 56 is actuated, the high-pressure valve controling the unloading valve through a relay valve 38. When the accumulator is fully charged a pressure of, say, 1500 psi is applied to the valve 32 to connect a line 20 to a reservoir line 12 and allow fluid to flow through an orifice 24 from a line 18. The pressure drop across the orifice opens the valve 38 when it reaches 50 psi so that the line 20 has a further parallel flow path to the reservoir through a line 52, the already open low-pressure valve 56 and a pilot flow limiting valve 46 which is opened by the pressure drop across an orifice 44 whenever the valve 56 is open. The further flow thus provided through the orifice 24 opens the unloading valve when the pressure drop reaches a value of 100 psi. When pressure in the system falls, say, to 1400 psi the valve 56 and hence the valve 46 close to stop flow through the orifice 24 and thus close both valves 38 and 26. The valve 56 has a spring chamber 60 connected to the inlet to provide rapid closure as the system pressure falls. All of the valves are mounted in a common housing and orifices 80, 82 and 84 operating in conjunction with oil reservoirs, such as 90 damp the movements of the valves 26, 38 and 46. A further orifice 74 operating in conjunction with a check-valve 72 provides a rapid opening and slow closing characteristics for the valve 26. The high and low-pressure responsive valves are loaded by manually adjustable springs.
