Title: Improvements in or relating to helical hearth furnaces
IPC: F27B3/18
Filed: 1922-02-13
Abstract: 202,331. Laurent, E. Bracq-. Feb. 13, 1922. Charges, agitating.-Relates to helical-hearth roasting-furnaces such as described in Specifications 20108/12 and 26736/13 and consists of simplified means for maintaining automatically the complex movements of the rabbles comprising the upward step-by-step rabbling movement and the idle downward movement with the rabbles raised clear of the hearth. The rabble-shaft is, as before, connected to a shaft 3 from which its movements are obtained. The shaft 3 is formed with a screw thread of pitch corresponding to that of the hearth and engaged by a large nut 28 which is prevented from rotation by vertical guides 30 mounted in the fixed framework but has a limited up-and-down motion thereon. The main movement is imparted to the shaft by a platform 5 rotated in one or other direction by a worm 7 and carrying a bridle 18 having pins 19 engaging longitudinal grooves 20 in the shaft. The bridle 18, being oscillated by an adjustablethrow crank mechanism 14, 17 mounted on the platform 5, imposes its oscillation on the steady upward or downward rotation of the shaft produced by the rotation of the platform. When the upward rabbling movement is in progress, a direct upward and downward movement is imposed in addition by means of an eccentric 21 carried on the crankshaft 11 and acting on the shaft 3 through the rocking lever 24 pivoted at 25 and engaging trunnions 26 mounted in a collar 27 rotatable between flanges, on the nut 28. The connection between the eccentric-rod 22 and the lever 24 comprises a bracket 47 mounted on the lever and formed with L-shaped slots to receive the connecting-pin 23<a> which is retained either in the end of the horizontal limb of the L (as shown) or in its vertical portion, by means of a tumbler 40a connected to it by a rod 39. On the rabble shaft reaching the upper limit of its travel the tappet rod 41 is lifted throwing the tumbler 40a over into its other position so that the pin 23<a> now oscillates idlv in the vertical limb of the L-slots and the rabble shaft, under the influence of counterweights rises to the top position allowed by the guides 30. At the same time the direction of rotation of the platform is reversed by tappets acting on the reversing belt and pulley gear 33, 34, so that the rabble shaft receives its idle downward travel with the rabble raised clear of the hearth. Similarly at the) end of the downward movement of the rabble shaft the gearing 33, 34 and the tumbler 40a ara again reversed. The shaft 11 is driven by an electric motor mounted on the platform 5.

Filed: 1953-02-17
Abstract: Sub-microscopic crystalline forsterite having a bulk density, when substantially all passes a 200 mesh, of 45 to 85 lb./cu. ft. is prepared by mixing a finely divided magnesium compound convertible to magnesia on firing with 20 to 60 per cent of silica having a specific surface of at least 6000 sq. cms./gm. and a bulk density less than 25 lb./cu. ft., and calcining.  The silica may be silica fume or diatomaceous earth.  Specification 639,581, [Group V], is referred to.ALSO:A refractory bond of magnesia and silica has a substantial proportion thereof as submicroscopic crystalline forsterite having a bulk density, when substantially all passes a 200 mesh, of 45 to 85 pounds/cubic foot.  Excess of magnesia or silica may be present but when silica is in excess the refractory material to be bonded contains magnesia for reaction therewith.  A temporary bond may be added before calcining the mixture to form the bond.  The bond can form a mortar in combination with, e.g. chromite, brickbats, or water-glass (to give an air setting composition).  The bond is used to form shapes of natural spinels, e.g. chromite, or artificial spinels, e.g. magnesio-ferrite.  The magnesia can be obtained from a compound yielding it on firing, and the silica may be a fume or diatomaceous earth.  Specification 639,581 is referred to.
Patent GB-754939-A (GB)
Title: Tires
IPC: B29D30/40
Filed: 1954-02-16
Abstract: In a tubeless tyre (see Group XXXIV) having a carcase of rubberized plies of separate or fabricized cords of twisted synthetic continuous filaments, loss of inflation air by "wicking" along the interstices between the filaments is prevented by impregnation of the cords with a rubber latex solution to fill the interstices at least in the outer peripheral region of <PICT:0754939/IV(c)/1> the cord.  The impregnation may be effected by dipping the cords whilst in a relaxed state and subsequently tensioning them to compact the filaments. Preferred impregnants comprise mixtures of rubber latex with (1) a protein and/or (2) a soluble aldehyde resin, or (3) an aldehyde and a reactant capable of forming a resin therewith, and the degree of impregnation is considerably greater than that required for adhesion purposes.  Fig. 3 shows applied to a two strand cord, how filaments 10 which may lie in the central unimpregnated part of the cord at one section, progress to lie, in the formation of the cord, in the impregnated outer periphery of the cord at nother section.  This effects at least periodic damming of the interstices sufficient to prevent "wicking".

Title: A self-separating electrical pin and socket connector
IPC: H01R13/633
Filed: 1949-02-21
Abstract: 657,458. Two-part couplings. BURTT, H. H. Feb. 21, 1949, No. 4687. [Class 38 (i)] In a self-separating pin and socket connector; each pin contact carries a spring biassed ejecting sleeve adapted to be depressed by the socket contacts as the parts of the connector are engaged and to individually force the socket contacts off the pin contacts when said parts are released. Fig. 2 shows a multiple contact connector in which the body of each part 21, 31 comprises a single moulding. Part 21 carries the pin contacts 51 in bores 52, each contact having a flange 84 bearing on a shoulder 54 and prevented from moving axially by a spring clip 55 engaging the outer face of the body. Slidable on each pin against a spring 96 is an ejector sleeve 93 its outward movement being limited by a spring clip 92. Mounted respectively in larger bores 56, 57 in opposite sides of the part 21 are a centering and locating socket and pin 58, 59 which co-operate with a pin and socket 74, 75 carried by the part 31 in which the socket contacts 64 are mounted in a similar manner to the pin contacts 51. Recesses 77 round the sockets receive projections 78 on part 21 so as to increase the leakage path between pairs of connected contacts. Fig. 1 shows the connector applied to a rack for a radio device 16. The device, carrying the part 31, is slid into the rack so that the sockets engage the pins in part 21 mounted at the rear of the rack at the same time depressing sleeves 93. The connector parts are mounted by means of washer-like pieces 24, 37 engaging flanges 23, 36 thereon respectively. A nut 44 on a hinged bolt 45 is engaged with a lug 43 on the device to retain the latter in the rack. On release of the nut and withdrawal of the device the ejector sleeves effect instant disconnection of the connector contacts. Where the invention is applied to the free coupling of two cables, the ejector springs may be sufficiently strong to effect disconnection of the connector parts by themselves when suitable locking means is released.
