Abstract: 1,075,221. Thin-walled plastics containers; container closures; venting containers. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Aug. 21, 1964 [Aug. 23, 1963], No. 34299/64. Headings B8D, B8T and B8X. A thin-walled plastics container 1 has a flexible element 9 which is in communication with the outer air through apertures 4 in a cover 2. If a reduced pressure develops in the container, air is drawn into the chamber formed by the element 9, which expands, thereby preventing the container walls from being deformed. The element 9 may be in the form of strips welded or glued along their edges and be made of a flexible polymer or metal foil. The container 1 may be made of a polyolefine or laminate, and may contain motor oil. The element 9 may be connected to the cover by a rigid tube (10), Fig. 5 (not shown), and be located in the container base, Fig. 9 (not shown); or the cover 2 and element 9 may be in the top and base of the container respectively, Fig. 7 (not shown). The element 9 may also be in the form of a bag the mouth of which closely surrounds a single aperture (4), Fig. 6 (not shown); or it may be formed with bellows folds surrounding a basal aperture, Fig. 8 (not shown). The container has closed pouring spouts 8 the ends of which are cut off before use. The cover 2 is glued or welded to the container.

Filed: 1927-12-19
Abstract: 294,562. Hasler Akt.-Ges. vorm. Telegraphenwerkstõtte von G. Hasler. July 26, 1927, [Convention date]. Selective distant control systems.-The charging of a telephone sub-exchange battery B from a local source (e.g. lighting main) is controlled from the main exchange by dialling special numbers which effect starting and stopping. On dialling the number 8, relays Rr (slow-acting), Re energize over the wipers of the selector 8 and connect up relay RA which through relay Rg completes the charging circuit. Relay RA locks, so that the line L may then be used for ordinary calls. On dialling the number 9, relays Rr, Rd energize and connect up relay Rc, which opens the locking circuit of relay RA and thereby opens the charging circuit. The circuit of relay Rr includes the front contact of a relay bridging the line L to prevent charging being controlled by a local subscriber.

[Class 40 (ii)] In a magazine gramophone in which the records are stored horizontally on a support projecting from the centre shaft, the support is pivoted and spring-loaded to enable played records to be lifted off the shaft. The shaft may be journalled in a socket provided in the upper end of the driving shaft of the turntable, or may be dependent from the shaft of a motor above the turntable when used with changers for playing both sides of the records. The records 11 are supported by the U-shaped upper surface of a support 23, pivoted at 24 within the recessed shaft 10. A spring 25 urges the support outwards but allows it to retract, Fig. 3 (not shown), when records which have been played are lifted vertically from below. The records are fed by a pusher 22 pivoted at 19 in a slot 16 in a member 15, and having an inclined slot 20 engaging a pin 17 on member 15, so that when member 15 is depressed by the change mechanism, the pusher 22 moves to the right, displacing record 111 over the edge of the support 23, Fig. 2 (not shown), the upper edge of the nose 21 temporarily supporting the remaining records. In a modification, Figs. 5 ... 7 (not shown), the support is pivoted similarly to the pusher so that it is retracted during record feed, and is also spring-loaded as before.

Drawings to Specification. [Classes 40 (iii) and 40 (v)] A method of producing an image of a field comprises intensifying an image formed on a fluorescent screen by a moving spot of varying brilliancy produced by a continuously deflected beam impinging on said screen, by photo-electrically producing an electric picture current which varies in accordance with the fluorescent light spot formed by the impinging of said continuously deflected beam on said screen, and controlling the intensity of the beam in accordance with variations of the photo-electric picture current in such sense that the beam intensity is regeneratively increased by virtue of increase in brilliancy of the fluorescent light spot and is regeneratively decreased by virtue of decrease in brilliancy of the fluorescent light spot. The systems described are the same as those described in Specification 477,775 but the claims relate to the above, to apparatus for carrying out such method and to certain subordinate features.

Abstract: 829,914. Section insulators. BRITISH INSULATED CALLENDER'S CABLES Ltd. Nov. 15, 1957 [Nov. 15, 1956], No. 35009/56. Class 36. A section insulator 4 of resin - bonded inorganic fibre separating contact wires 1, 1A, is provided with guides 5 which gradually depress a current collector from one of the wires as it approaches the insulator, leads it past the insulator and returns it to the other wire. There may be two pairs 9, 10 of guides 5. Initially each guide runs close to the wire 1 or 1A to which it is secured by clips 7, 8, then extends outwardly and downwardly, then horizontally below the insulator 4 until it overlaps the horizontal part of the corresponding guide of the other pair. Each guide is then bent back to form a loop . The horizontal moving part of each guide is supported by a vertically adjustable clip 11 from an outrigger 6 on anchor fittings 2 securing the insulator 4 to the wires 1, 1A, the upper part of each guide being secured to the same outrigger by clip 12. The upper and lower parts of each guide are connected by a stiffener 13 carried by a horizontal bar 14. The loop end of each guide is secured to a resinbonded glass fibre rod 16 anchored to the contact wire which carries the other pair of guides. In a modified arrangement the bent-back portions of the guide are dispensed with. In a further modification (Fig. 2, not shown), there is only one pair of guides. In this case the looped part of each guide extends beyond each end of the insulator 4, the free ends of each loop being secured to the wire 1 whilst the loop ends are secured to resin-bonded glass fibre rods anchored to the wire 1A. Only the fitting 2 on wire 1 has outriggers 6, the parts of the guides near the other fitting 2 being supported by clips 11 carried on an arched bridge-piece rigidly connected to the lower ends of resin-bonded glass fibre rods depending from catenary 21.

Each shield 20 may be perforated at or near its base, and its open end may be partly closed near the bottom. The shields may reach to or be spaced from the top of the chamber 12. Adjustable louvres 22 and a thermostat 21 controlling the gas supply may be provided. A room thermostat controlling the gas supply and fan motor may also be provided. One or more heaters without fans may be located in a system of pipes through which air is caused to flow by the suction or pressure of a fan, or a fan at one side of the heater may draw or force air through it and into a pipe system. The heater may form part of a closed circulation system.

Under normal operating conditions the intake air is cooled by an aftercooler 16. In the embodiment of Fig. 1 the heat exchanger is placed in the intake manifold downstream of the aftercooler. Exchanger 39 may instead be remote from the intake manifold Fig. 2, (not shown), and may have its air input communicating with the open air, whilst a pressure releasing member (47), upstream of the aftercooler 16 vents the compressor 15 to the atmosphere. Alternatively the exchanger input may be connected to the intake duct at a point upstream of the aftercooler, Fig. 3 (not shown), in which case the pressure releasing member (47) is omitted.

[Class 83 (i).] Metal-pouring.-A mould 17, especially for casting aluminium alloys, is coupled in an air-tight manner to a rotating melting-chamber 1. The chamber 1 is mounted for rotation by a hand-wheel 8 or by power within an asbestos lined jacket 9 having heating means 10. The mould 17 is supported by a carriage 21 having lugs and stops 30, 31 to prevent longitudinal movement, but to permit lateral sliding to an unloading stage. During rotation of the chamber 1 a nozzle 16 on the mould is held frictionally in an outlet 3<a> of a conduit extending from the mould by a bolt 22 and a cotter on a bracket 23. For pouring, positive clamping is effected by bolts, and the whole assembly is tilted by gearing about trunnions 28<a>. A baffle plate 32 serves to remove scum. If the metal in the chamber 1 lies above the bottom of the outlet 3 a rotary plug may close the outlet during melting. A deoxidizing-agent may fill the chamber 1. A door in the chamber 9 may coincide in one position with the charging orifice 11, or, as shown, the upper part of the chamber 9 may be removable and secured to the lower part by bolts.
