Title: Method of and apparatus for utilising the heat of melting furnaces
IPC: H05B6/34
Filed: 1931-01-17
Abstract: 362,213. Furnaces ; thermo-electric batteries. VEREINIGTE STAHLWERKE AKT.-GES., 67, Breitestrasse, D³sseldor, Germany. Jan. 17, 1931, No. 1644. Convention date, Jan. 31, 1930. [Class 51 (ii).] Waste heat of melting furnaces is utilized by means of thermo-couples to generate electricity which is used for the electromagnetic agitation of the bath of metal. As shown, thermo-couples F are arranged with their hot junctions G in the flues C and their cold junctions H is a space D through which water is passed. The electric currents generated are.passed through the coils of electromagnets E, and through the metal in the bath, the arrangement being such that the metal is set in agitation.

Title: Melt spinning of synthetic textile filaments
IPC: B29C48/335
Filed: 1972-01-13
Abstract: 1386406 Melt-spinning apparatus PLATT INTERNATIONAL Ltd 13 March 1972 [16 March 1971 (2) 13 Jan 1972] 7009/71 7010/71 and 1692/72 Headings B5B and B5A A melt spinning apparatus comprises a melt producing unit 32 having a barrel 3 of non- circular cross-section which remains constant throughout the length of the barrel and a screw conveyer 13. In operation, polymer chips of, e.g., polyethylene terephthalate are supplied to barrel 3 from hopper duct 5, and owing to its non-circular cross-section, the barrel reacts against the chips between the screw and the barrel to prevent rotation of the material with the screw. The barrel may be of triangular, square, pentagonal, hexagonal, heptagonal, octagonal, oval, elliptical or semi-circular cross-section. The chips pass through melting grid 15 and the resultant melt is conveyed by metering pump 8 to spinneret block 12 where it is formed into filaments. The extruded filaments are quenched in known manner by a cross-current of quenching air supplied through foraminous block 20 of sintered metal. A spin finish is applied at roll 24 and the filaments after passage around feed roll assembly 28 are drawn between snubbing pin 30 and draw roll assembly 34 while passing over plate heater 32. Other forms of the apparatus (not shown) illustrate its adaptation to multistation operation by the use of common driveshafts replacing motors 6, 10 and 22, and its use in connection with known false-twisting, selftwisting and crimping apparatus.

In a vehicle suspension arrangement for resiliently connecting a fore-and-aft chassis member to two plates or the like each fast with the part on which one wheel of a pair is adapted to rotate, each plate has four pivots in pairs at two different levels all with fore-and-aft axes, a stirrup is suspended on each upper and another on each lower pair of pivots, two bars connect each stirrup to the chassis member by pivotal connections at different fore-and-aft positions and two further bars connect each stirrup with the corresponding stirrup associated with the opposite wheel, the further bars being pivotally connected at one end of each to the stirrup itself and at the other end to equal and opposite extensions of the respective radial arms of the stirrup beyond the pivot thereof on the plate. In the arrangement shown, in which a pair of wheels 2, 3 is attached to a pair of plates 4 and 5 respectively, stirrups 6 and 7 pivotally connected to the plate 4 are pivotally connected through pairs of bars 14, 14 to a rigid central chassis member 1. Each of the stirrups 6 and 7 is also connected through a bar 16 to an upwardly extending extension of a stirrup 8 or 9 associated with the plate 5 of the wheel 3, the stirrups 8 and 9 being also connected to the chassis member 1 by upper and lower pairs of bars 17, 17. In the arrangement according to Figs. 3 and 4 (not shown), the upper stirrup at one side of the vehicle and the lower stirrup at the other side are formed with upwardly extending extensions to which opposite ends of the bars 16 are pivotally connected, the other ends of the bars being connected to upper and lower stirrups on opposite sides of the vehicle. The bars pivoted to the chassis member 1 may be sprung against the member 1 by coil springs acting in torsion about the points of pivotal connection, or by torsion blade springs arranged parallel to the member 1. In a modification, Fig. 9 (not shown), each upper stirrup may be operatively connected to the lower stirrup by a link.

Abstract: 599,791. Hydraulic accumulators. WELLMAN SEAVER ROLLING MILL CO. Ltd., and BROOKS, C. Feb. 4, 1944, No. 2114. (Class 69 (ii)] In order to avoid shock loads in a weight-loaded hydraulic accumulator, the weight 5 is connected to the cylinder 4 or piston of an air cylinder, the other member of which is subjected to the liquid pressure in the accumulator. In one form, the movable ram 2 has a projection 3 forming the piston of an air cushioning device, the cylinder of which carries the weight 5. In another form, a number of pistons carried by the weight co-operate with air cylinders supported on the accumulator ram. In a further form, the weight is supported on a movable accumulator cylinder 1 having a hollow extension 16 projecting into a cylinder 17 which forms the piston of an air cushioning cylinder 4 carried by the weight. Alternatively, the weight may be mounted on a movable ram, which is then provided with the extension 16. In each case, in the event of sudden stoppage of the water flow from the accumulator, the weight is cushioned by the air cylinder.

Abstract: 1372926 Associative store INTERNATIONAL BUSINESS MACHINES CORP 17 Jan 1972 2229/72 Headings G4A and G4C An associative binary store 1 comprises fixed length search and read fields 5, 6, comprising bi-stable circuits, input and output registers 2, 3, and a coder and decoder 4, 7, respectively. A duplicate input register 2A is connected to register 2 through a comparator C to form a shift register. The register 2A is used for checking the accuracy of the data transmitted to register 2 from external sources and in initially loading the associative store. A search argument is placed in register 2, is coded by coder 4 and compared with the search fields 5. The result appears on lines 8 and causes a corresponding read field to be read out through decoder 7. The bi-stables of the associative store may be half the 4 state cells described in Specification 1,127,270. The store is controlled by microinstructions and in one mode of operation the contents of register 3 can be selectively written into fields 5 or 6. The microinstructions can control a number of stores I and one store may be used to check the loading of another. The store 1 may be a read only store and error detection and correction by means of a diagnostic routine is described. In other embodiments (Figs. 5 and 6, not shown), the circuit 1 can be used as a logic circuit for table look up.

Abstract: 218,218. Schmitt, N. E., and Schmitt, 0. Jan. 28, 1924. Blasting fuzes.-The conductors of electric fuzes are stamped from sheet metal a, Fig. 1, into pairs of tongues 1, 2 all in one plane with marginal strips 3, 4. The stamped sheet is then sandwiched between layers of celluloid or cellon b and pressed in a heated mould. The upper marginal strip 3 is then removed, the ends of the tongues thus freed are dipped in the priming material, to form the heads 5, and finally the complete fuzes e are separated from each other by the removal of the lower marginal strip 4. Where wire ignition is desired, the upper ends of the pairs of tongues are more widely separated and are bridged across by a wire l, Fig. 3, which is electrically welded or soldered to the tongues in a groove made in the sheet before it is stamped out, the sheet being tinned wholly or only at the groove when soldering by heat is adopted. The leads are attached to the conductors 1, 2 by making holes f<1>, slots, or raised up slit parts d<2>, Fig. 5, in the ends of the conductors, and inserting and riveting or clinching therein the ends of the leads h. The connection may then be sprayed with metal.
