IPC: F42D1/10
Filed: 1970-08-05
Abstract: 1300609 Blasting ICI (AUSTRALIA) Ltd 5 Aug 1970 [22 Aug 1969] 37800/70 Heading F3A [Also in Divisions C1 and E1] An apparatus for loading into a confined space a pourable, pumpable or blowable material which is susceptible to deterioration in contact with water, e.g., an explosive charge or a foundation forming material, comprises, a water-resistant, flexible tubular liner 2, Fig. 1, folded in concertina-fashion in an annular space between rigid tubes 3 and 5. The apparatus is suspended above the space 1 or introduced therein, and the liner is extended into the space, whilst being filled with the loading material which is fed through a hose 4. In the case of an explosive charge, a primer 8 is provided to cause detonation. The lower end of the liner may be perforated so that any water in the space 1 can enter the apparatus as it is introduced into the space: this equalizes the pressure on opposite sides of the liner and thereby prevents rupture. However, on introducing the loading material, the water is expelled from the liner without loss of the loading material owing to the size of the perforations. In another embodiment the liner is supported by a one way valve (14, Fig. 3, not shown) as the apparatus is introduced into the space. A cap (15, Figs. 4 and 5, not shown) is provided to protect the liner, and a rubber ring (18, Figs. 6 and 7, not shown) is arranged to unfold and guide the liner as it is extended. In another embodiment, Fig. 12, the apparatus is connected to the loading tube 4 by an adapter 28, and a ball valve 29 or a flap valve (27, Figs. 11 and 13, not shown) permits the escape of gas where the loading material is gas-propelled. An expansible core (not shown) may be provided in the bottom end of the liner. The tubes 3 and 5 may be circular, oval, square, hexagonal, octagonal or of irregular cross-section. The tube 3 may be tapered. The tubes are formed of aluminium, iron, P.V.C., polyethylene, polypropylene, polyethyleneterephthalate, acrylonitrile - butadiene - styrene rubber, timber or paper. The liner is made of textile or paper, polyethylene, P.V.C., polyethyleneterephthalate, nitrocellulose or rubber. An explosive charge for loading with the apparatus comprises a composition of ammonium and sodium nitrate, aluminium, sugar, water, surfactant and thickening agent.

Title: Thermally responsive snap-acting electric switch
IPC: H01H71/04
Filed: 1957-12-06
Abstract: 882,105. Thermal switches. TEXAS INSTRUMENTS Inc. Dec. 6, 1957 [April 8, 1957], No. 38095/57. Class 38 (5). Contacts 36, 38 carried on terminals 40, 42 fixed in a base 12 are bridged by contacts 28, 30 on a bimetallic disc 20 which is mounted on a post 18 threadedly engaged in a bush 16 in the base 12. Heating, such as by current overload, causes disc 20 to snap upwards into the position shown in Fig. 3; normal fall of temperature is preferably insufficient to cause the disc to return and resetting is effected by a push-button 54 which depresses a resetting member 56 having two projections 58 and 60 to engage disc 20. A projection 62 on member 56 and a corresponding projection (not shown) on disc 20 engage in a groove 66 in the side wall of base 12 to prevent rotation of members 56 and 20. The flange 26, which holds disc 20 on to the post 18, acts as a stop to limit the downward motion of member 56 such that it cannot be held in engagement with disc 20 when the latter has snapped downwards (Fig. 5), and the switch is thus rendered trip-free, i.e. the contacts 36, 38 cannot be kept bridged by holding button 54 depressed when the disc 20 is above the maximum resetting temperature. The button 54 is biased downwardly by spring 86 which also serves to hold member 82 against a rubber gasket 74 and cover 72. The spring bias is such, however, that it is overcome by disc 20 when actuated (Fig. 3), and hence the position of button 54 indicates the condition of the switch, and a coloured band 88 may be provided on the button 54 to render its position more obvious. Specification 178,103 is referred to.

Title: Method for continuously forming high filler content composite  panels and shapes
IPC: B29C67/00
Filed: 1974-09-03
Abstract: 1427505 Resin-fibre composites; web formation MATERIAL SYSTEMS CORP 3 Sept 1974 [17 Sept 1973 9 Aug 1974] 38490/74 Headings DIN and D1R A rigid fibre reinforced resin sheet contains inorganic nonflammable filler particles in excess of 20% by weight. A mixture of polyester resin and filler is spread from puddling box 28 to form a layer on an impervious polyester carrier film 30 or endless belt. A multifilament glass jute or sisal roving 40 is cut into “ to 4 inch lengths by rotating knife 46 and the cut lengths separated into individual fibres by beater bar 48 and by the turbulence of a stream of air which ascends duct 38 from manifold 50. A randomly orientated fibrous layer is thus deposited upon the resin/filler layer. If desired additional, coarser filler may be added from hopper 52 and additional resin/ filler mixture from puddling box 60, the additional resin/filler being applied to an upper covering 58 (e.g. a polyester film) which is placed on top of the composite. The composite is kneaded during an undulating path between rollers 68 or by passage between successive sets of upper and lower rollers, each exerting a different pressure upon the composite and rotating at a slower linear speed than that of the composite. The composite is passed through a first oven 70 so that vulatiles in the resin migrate to the upper surface, forming bubbles under cover 58. These are removed by the action of oppositely inclined blades or squeegees 74 which may also form corrugations or channels in the sheet. The sheet is then cured in oven 76 and the carrier films 30, 58 are removed. The surfaces of the composite are rich in resin due to resin migration. The composite may contain 1-5% by weight of methyl methacrylate, acetone or styrene as resin dilutant. The filler added to tank 10 comprises 500 to 1000 mesh alumina or calcium carbonate and preferably comprises 50% by weight of the material in the tank. Coarser (e.g. 200 mesh) sand may be supplied from hopper 52. The glass fibres comprise 5 to 40% by weight of the composite.

[Classes 51 (i) and 51 (ii).] Some or all of the products of combustion from the regenerators of coke ovens, glass furnaces, Martin furnaces, &c. are passed directly into a steam boiler, the temperature of such products being increased by preheating the air supplied to the regenerators, using for this purpose the residual heat of the products of combustion, which residual heat cannot be utilized in the boiler on account of its low temperature. Fig. 1 shows two furnaces 1, 2 having regenerators, those of the furnace 1 being supplied at 5 with air at normal temperature and the waste gases from this furnace passing from the regenerators through a pipe 6 to an air heater 3 and chimney 7. Air supplied to the heater 3 at 8 passes by a pipe 9 to the regenerators of the other furnace 2 the products of combustion from which pass direct into the steam boiler 4 and thence to the chimney 10. The regenerators of a single furnace may be divided into two parts corresponding to the furnaces 1, 2. Fig. 3 shows a modification in which the boiler 4 and air heater 3 are arranged in series, the boiler being byepassed by a pipe 13 at starting. The air heated in the heater 3 is supplied to the regenerators of the furnace 1, and a valve in the byepass is operated by a thermostat 11 influenced by the temperature of the products of combustion leaving, or of the air entering, the regenerator, so that as this temperature rises a part or the whole of the products are admitted into the boiler. Specification 310,756, [Class 51 (i), Furnaces and kilns, Combustion apparatus of], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a form in which the air heater and boiler are arranged in parallel.
