Abstract: 668,084. Drawing wire. VAUGHN MACHINERY CO. Dec. 21, 1948 [Dec. 22, 1947], No. 32985/48. Class 83 (iv). Automatic stop means for a wire-drawing machine having a series of dies 6 and associated motor-driven drums 1 comprises rotatable means arranged adjacent the first drum and driven by the travel of the wire and a speed switch 16 connected to the rotatable means so that it cuts off the supply of current to the motors on breakage of the wire. Immediately preceding each die 6, the wire is guided by a sheave 15, or a pair of pinch rolls 17 and 18, and the sheave or one of the pinch rolls is connected by gearing 24, 23 to a rotary disc 19 in a fluid-filled housing 21. During normal operation, the drag of the fluid causes disc 19 to rotate another disc 20 against the action of a spring until a lug 25 closes contacts 26 that operate a relay 28 to close the driving motor circuit. If the wire should break, the spring rotates the disc 20 in the opposite direction and opens the contacts 26, so stopping the entire machine. In a modification electromagnets may be fitted on the disc 19 to take the place of the fluid drive. The wire-drawing machine illustrated has tension-controlling arms 10a which control the speeds of the individual motors for each drum, as described in Specification 555,933.

Title: Improvements in tandem axle suspensions for vehicles
Inventor: WALTER ROBERT JAMES
IPC: B60G5/04
Filed: 1957-10-24
Abstract: 840,515. Leaf-spring suspensions. TRUCK EQUIPMENT CO. Inc. Oct. 24, 1957, No. 33256/57. Class 108(2). A chassis 10, Fig. 2, is supported on axles 18, 22, of tandem wheels 17, 21 by a beam 24 which rests on ends 71 of rock arms 70 and contains leaf springs 60, 62, Fig. 3, by a support block 47 and a bracket 45. A similar beam 25, Fig. 1, is provided at the opposite side of the chassis. Two groups 60, 62, Fig. 3, of leaves are used in the spring and they are progressively compressed as the load increases, more groups could be used. A rubber bump stop 65 prevents undue rebound of the chassis member 10, to which it is connected by a member 39, with respect to the beam 24. Longitudinal spacing rods 100 act between the support block 47 and rubber blocks 108 supported by fixed transverse walls 81 and bolts 110. Heads 71 of rock arms 70 bear against the beam 24 through blocks 74, limited longitudinal movement with respect to the beam being permitted by rubber inserts 85, 86. Links 120, 121, Figs. 1, 2, pivoted at both ends about axes at right angles to their length, ensure a self-steering action, since when either axle 18 or 22 tends to move axially a turning movement is imparted to the axle, by virtue of the resilient mountings of the links, which tends to steer the axle back into line. Wear plates 140, 141, Fig. 1, limit lateral movement of the beams 24, 25. Fig. 8 shows a modification in which seat members 194, 195 for rubber cushions 203, 204 and bearing members 199, 200 for heads 191 of rock arms 190 are differently shaped. Also, a rubber block 212 is not bolted in position. In the unloaded condition the top leaf of stack 185 is arched upwardly to contact the lower leaf of upper stack 186 to prevent the leaves becoming unseated. Support means 44, 47, of Fig. 3, and 176, 177 of Fig. 8, may be located at any point between the ends of the longitudinal beams so that the weight may be distributed between the two axles in any preferred ratio.

Patent GB-605105-A (GB)
Title: The production of perforated sheets of thermoplastic resin compositions
IPC: B29C48/91
Filed: 1945-12-14
Abstract: <PICT:0605105/IV(a)/1> A perforated or reticular film or sheet is obtained by covering, with a dispersion of a finely powdered thermoplastic polyvinyl resin in a practically non-volatile plasticiser in which the resin dissolves only very slowly or not at all at ordinary temperatures, an engraved metal surface in which are grooves each of which at a number of places meets or intersects other grooves, removing from the surface the dispersion which has not collected in the grooves, gelatinizing by heat the dispersion which has collected in the grooves, and removing the gelatinized material from the grooves when it has been cooled sufficiently for it not to adhere to the metal.  The polyvinyl resin dispersion is preferably pressed well into the grooves by means of a spreader bar or cylinder. The engraved metal surface may be polished and it may be coated with a film separating aid, such as a high melting point grease, aluminium or zinc stearate, a glazing material such as sodium silicate, or a detergent.  The grooves should be free from undercuts to avoid difficulty in stripping the perforated sheet. The polyvinyl compound may be a polyvinyl ester, polyvinyl chloride, an interpolymer of vinyl chloride and a vinyl organic ester or of vinyl chloride and an acrylic or substituted acrylic ester, or a polymer of an acrylic or substituted acrylic ester. The non-solvent plasticizer may be dibutyl phthalate, tricresyl phosphate, dihexyl phthalate, and dioctyl phthalate.  Heating of the engraved surface may be obtained by means of hot fluids, infra red heating lamps, or induction heating means. The perforated sheets may be used as curtains, fishing nets, filters and strainers, nets for protecting plants and trees, fancy wrappings, scrim packaging for meat in cold storage, and in the production of lamp-shades and uppers for shoes.  As shown, a dispersion of polyvinyl resin 2 is fed on to a cold portion of roller 1 from a tray 3 and is carried past a stationary roller 4 which forces it well into the grooves of roller 1.  A doctor knife 5 removes any dispersion which is not in the grooves.  Heated rollers 6 contact the surface of the hollow roller 1 and supply heat for the gelatinization of the dispersion in the grooves.  A flexible fibrous backing material 10 may be fed on to the surface of the roller 1.  Cooled rollers 7 contact roller 1 and cool the perforated resin sheet sufficiently for it to be easily stripped by the cooled roller 8.  Specifications 500,298 and 566,388 are referred to.

Title: Methods of determining neutron absorption and multiplication parameters of nuclear fuels in cluster-type configurations
IPC: G21C17/06
Filed: 1969-07-04
Abstract: 1281703 Fuel elements; moderating neutrons SNAM PROGETTI SpA 4 July 1969 [4 July 1968] 33940/69 Headings G6C and G6P In order to derive the thermal and epithermal neutron absorption and multiplication parameters of a cluster-type nuclear reactor fuel element, it is mounted within a cylindrical moderator column and irradiated by a neutron source at the column base. The fuel cluster, 2, is mounted in the channel, 11, in the graphite or D 2 O moderator, 1. The thin cadmium layer, 8, prevents lateral neutron leakage. The neutrons, injected through the base, 3, may be supplied from the outer face of a reactor. The radial and axial distributions of thermal neutrons are determined by detectors 4 and 5 respectively. Epithermal neutrons are detected at 6, 7. The uranium detectors, 9, measure the conversion ratio. Correlation of the experimental results is effected in formulae derived from quadratic error considerations. In an alternative form, a neutron "1/v" poison is inserted into the arrangement so as to compensate for the effect of the fuel in the moderator.
