Filed: 1971-05-17
Abstract: 1360787 Heat exchange apparatus for granular materials; shaft furnaces BRITISH GLASS INDUSTRY RESEARCH ASSOCIATION 10 Feb 1972 [10 Nov 1970 17 May 1971] 53456/70 and 15288/71 Headings F4U and F4B A compacted bed of granular material 15 passes by gravity in counterflow to a gaseous fluid introduced at inlets 6 and escaping at outlets 9 in a shaft furnace 2 which is divided into a leading zone 11, an intermediate zone 12 and a trailing zone 13, defined in the Specification by boundaries 20, 21 at the levels of the inlets 6 and outlets 9 respectively. The zones and mass of gas flow are so proportioned to achieve a predetermined heat or mass transfer between the gas and material and the resistance to fluid flow through the zones 11 and 13 keeps the gas flow predominantly within the intermediate zone and without causing fluidization of the material. The fluid may be for heating or cooling, e.g. heating granular refractory materials preliminary to melting glass, and hot gas may be formed at a distance from the shaft, within one or more of the furnace walls as by combustion, or carbon may be mixed with the material to be burned in the intermediate zone to which compressed air is added through the inlets 6. A plurality of shafts may be fed with material from an upper header.

Convention date, April 24. [Class 83 (iii).] Lathes and like machine tools with hydraulic stepless gear drive have their speed of rotation controlled either by a handle mounted on the carriage or by the movement of the cross slide, the latter arrangement enabling a constant cutting speed to be maintained while surfacing. A sliding plate 3, controlling the speed of a pump and motor of the stepless gear, is moved by rotating a handwheel 12 on the carriage apron, which in turn rotates a wheel 13 slidable on a shaft 1 connected by gearing to the plate. The draw spindle of the cross slide is connected, through gears 7, 8, 9 and clutch element 15, to a shaft 20 for automatic feed, and also through bevel gearing to the speed controlling wheel 18, thus enabling a constant cutting speed to be obtained during automatic surfacing by the slide 6. The wheel 8 is made slidable so that the automatic speed controlling gear can be disengaged from the cross slide for adjustment by the wheel 12.

Filed: 1916-10-28
Abstract: 126,024. Pennington, L. T. M. Oct. 28, 1916. Projectile fuses, and apparatus for setting.-Relates to distance fuses of the kind in which a firing-pin is retained in a cocked position by an arm or trigger adapted to be released by a motordevice such as a vane wheel. According to the invention, the motor device is arranged so as to approach the trigger and to release it after it has moved through a predetermined distance. In the fuse shown, which is for an aircraft bomb, a spring-pressed firing-pin or striker f is arranged within a tube b, screwed externally, a trigger arm h<1> on the striker engaging in a notch in the tube so as to hold the striker cocked. A nut c, adapted to travel on the tube b, has vanes c<1> and also has a sleeve k with which a loose cap j can be engaged for the purpose of setting the nut initially. As the bomb drops, the nut rotated by the vanes moves upwards, and eventually a lug s on the nut pushes the arm h<1> out of its notch into a vertical slot, thereby setting the striker free to act. Means may be provided, such as an arm pivoted on one of the fixed wings r, as described in Specification 124,459 for preventing the winged nut from being rotated whilst passing through the air, but releasing it on striking water. A safetypin for locking the arm h' in the notch, and adapted to be withdrawn by a wing or float, may also be provided. In a modification, instead of adjusting the nut c initially upon the tube b, the position of the trigger h<1> along the striker may be adjusted. Fig. 3 shows a setting-device for rotating the nut c through a given number of revolutions before the bomb is dropped. It comprises a spindle n connected to the cap j, Fig. 1, by a Bowden wire l or the like, and having on it a nut m with an indicating arm m<1> passing through a graduated slot.

Abstract: 1,197,903. Moulding concrete elements; laminates. J. W. PEDLOW. 5 April, 1967 [12 April, 1966], No. 15545/67. Headings B5A and B5N. [Also in Divisions B1, B2, C7, E1 and F2] Concrete building elements are cast in a mould lined with a layer of P.V.C. bonded to a backing layer of foamed polyurethane internally coated with P.V.C. The foamed layer is penetrated partially or wholly by the wet concrete during casting and anchors the P.V.C. layer firmly to the cast element. The P.V.C. layer may be covered by a layer of release coated paper, which layer forms a medium through which the P.V.C. - foam laminate may be attached to the mould wall. The paper layer is retained by the mould upon removal of the cast element. The P.V.C.-foam laminate may be completely pre-formed prior to application to the mould or the mould may be dipped in a P.V.C. bath and a preformed foam layer stuck to the P.V.C. layer thus formed. Plaster of Paris, resinous, waxy or bituminous materials may also be cast on to the laminate. The P.V.C.-foam laminate is made by casting a layer of P.V.C. plastisol upon a release belt, partially gelling the layer, cooling the gelled layer, applying a preformed internally coated foamed layer by passage between nip rollers, and finally heating the laminate thus formed to fully cure the P.V.C. and to effect the bond between the layers. Bonding may be enhanced by gelling in such a manner as to leave a thin ungelled coating upon the partially gelled layer. Alternatively a separate ungelled coating may be applied. A second P.V.C. layer may be applied to the foam to form a sandwich structure.

Title: Improvements relating to foamed products from halogenated styrene polymers
Inventor: ANDERSON WILFRED DE FERRY
IPC: C08J9/04
Filed: 1962-04-24
Abstract: In a process for the production of foamed halogenated styrene polymer by heating the polymer containing a normally liquid or normally solid blowing agent, the polymer, before or during the foaming operation, is homogenized by extrusion.  "Halogenated styrene polymer" is used to denote styrene polymers that have been halogenated after polymerization of the monomer as opposed to polymerized halogen-substituted styrene monomers.  The polymer may be derived from mono- or polymethyl styrene and may contain a small proportion of a divinylbenzene polymer, added before or after the halogenation. A chlorine content of 25-40% in the chlorinated polystyrene is satisfactory.  A proportion, e.g. 50 to 300% of unchlorinated polystyrene can be mixed with the chlorinated material.  As blowing agents hydrocarbons, dichlorodifluoromethane, bromochlorodifluoromethane, p,p1-hydroxy-bis (benzenesulphonyl hydrazide), benzene sulphonyl hydrazide, azodicarbonamide and azodiisobutyronitrile are suitable.  A twin screw extruder is preferably used in carrying out the process.  In examples (1) a mixture of water, basic calcium phosphate, pentane and ground chlorinated polystyrene is heated in an autoclave charged with carbon dioxide. The pentane-containing product, after drying, is extruded at 100 DEG C., to give a foamed sheet; (2) a ground mixture of chlorinated polystyrene, polystyrene and p,p1-hydroxy-bis(benzenesulphonyl hydrazide) is extruded at 160 DEG C.; (3) a mixture of chlorinated polystyrene, isotactic polystyrene and azodicarbonamide is compounded on a twin-roll mill and extruded at 200 DEG C.; (4) and (5) examples 2 and 3 are repeated, but the ingredients are ball milled and pelleted before the extrusion.
