Abstract: 1,168,464. Tapping containers; stoppers; bunghole bushes; venting containers. C. H. MALPAS. 14 Nov., 1966 [19 Nov., 1965; 29 Nov., 1965], No. 50986/66. Headings B8T and B8X. A liquid container, provided with a tapping socket 34 into which a tap 27 may be fitted, is vented after cutting off the top of a hollow plug 26 fitted within a collapsed air bag 32 so that the upper wall of the bag surrounds the plug. In place of a vent plug the bag may be attached to a tube secured in the container wall; or the vent plug may have a through passage, Fig. 3 (not shown) sealed only by the bag wall at its upper end. The plug 26 may have a filter or an inlet valve. The container may be of tinplate and sprayed internally with lacquer. The bag may be of polypropylene with or without a coating of " Saran " (Trade Mark) or of polyethylene which may be similarly coated; or an inner bag of air-impervious material may be enclosed in an outer bag compatible with the liquid, e.g. milk or wine, in the container. Tapping.-A pair of holes in the container wall receives the socket 34 and locating plug 35 respectively, Fig. 5 (not shown). A plug, protecting a diaphragm (36), is removed and the tap, Fig. 9, inserted until held within the container wall by a bead on the inner end of a neck 43. An apertured cylindrical portion 47 is rotatable by a finger piece 50 to align it with a spout 41, thereby drawing off the liquid. The socket 34 may have slits (55), Figs. 6-7 (not shown), through which arms (60) on the protecting plug pass to provide a tamperproof closure. The socket may be held non-rotatably in a square hole in the container wall and itself similarly hold a square flange on the tap, Figs. 10-12 (not shown).

A flattened plastics tube folded asymmetrically longitudinally about a line 14 (Fig. 6) is heat sealed along lines 21, 22, 23 to give a bag with an open neck. The initial tube may be formed by welding a sheet, and the weld (41) (Fig. 17, not shown) may be made at the same time as the transverse welds. Several bags are preferably formed simultaneously, as in Fig. 6, to be torn apart at the welds. The welds may be performed by an upper reciprocating die as the material is fed over a flat plate electrode of a high frequency welding press. The same die may be used for several sizes of bag. Tabs (3) (Fig. 7, not shown) between the bags may be provided with holes 25 so that, when the bag is to be used for an ice pack, it may be tied to the patient with a string passing through the holes. If the bag is to be used as a hot water bottle, a covering (36) (Fig. 13, not shown) in imitation chamois or formed from sheet material made of gossamer thin sheets of cellucotton pressed together, may be folded around the folded tube 13 and heat sealed to the bag during its formation. Closing the mouth. After folding the neck about lines (30, 31, 32) (Fig. 8, not shown) it is rolled over onto a piece of double-sided adhesive tape (28), which may have a removable protecting sheet (29). Alternatively a piece of stiffer material (33) (Fig. 10, not shown) may be attached to the neck at (12) and the neck of the bag rolled round this and closed by snap fasteners (34), (35). The fastened strip can then be used as a handle.

A battery charging system for a road vehicle comprises a generator 14 for charging the battery 11 and a voltage regulator for the generator, the regulator having a sensing stage 15, 16, 17 which senses the battery voltage, and a control stage operable by the sensing stage for varying the current flow to the field winding 23 of the generator to regulate the output voltage thereof, the control stage being connected to the battery through the series circuit of a resistor 25, e.g. a warning lamp, and the ignition switch 26 of the vehicle, the said sensing stage being connected directly across the battery, i.e. not through the ignition switch, at least when the ignition switch is closed, and means being provided for effectively shortcircuiting the said series circuit when the generator produces an output. As shown in Fig. 1, the control stage may include a transistor 22 having its collector/emitter path in series with the field winding 23 and its base connected over a resistor 19 and a line 21 to the series circuit 25, 26, alternatively, the control stage may include a contact in the field circuit, the opening and closing of the contact being controlled by a voltage sensing coil Fig. 2, (not shown). The means for shortcircuiting the series circuit 25, 26 may comprise a switch operable by the generator output or, when the generator is constituted by an alternator with a rectified output, the means may comprise additional diodes 27 connecting the phase points of the alternator to the line 21 so that the potential on line 21 can reach that on line 12 when the generator produces an output. In operation, initial closure of the ignition switch 26 allows current to flow through the lamp 25 and the field winding 23; when the generator output has built up sufficiently the series circuit 25, 26 is effectively shortcircuited by the diodes 27 so that the lamp 25 is extinguished, the field current, under the control of the voltage regulator, then being supplied by way of the diodes 27.

Abstract: 1370003 Riveting; forging; welding by pressure GRUMMAN AEROSPACE CORP 10 Sept 1971 54521/73 Divided out of 1370001 Headings B3U B3H and B3R A metal workpiece is deformed or spot welded by electromagnetically generating a stress wave, amplifying the stress wave to increase its intensity and duration and applying the wave to the workpiece. The stress wave is generated by charging a capacitor bank 28 by a D.C. source 32 and thereafter discharging it through a pancake coil 12 to produce a magnetic field around the coil 12. A current is induced by the field in an aluminium or copper driver 14 causing a second magnetic field to be set up which interacts with the other field to cause a stress wave to be generated. The stress wave produced is amplified by a conically or exponentially shaped steel member 16 and is passed into the workpiece 18 to render it plastic. The wave is reflected by a mass 20. A shock absorber 10 consisting of rubber pads is attached to the coil 12. Two metal parts can be spot welded together by focusing the stress wave on one of the parts to cause the point of contact to locally melt by the heat generated. One of the parts may be heated. The tool, which can be portable, may also be used for forging or riveting a workpiece below its recrystallization temperature.
