Abstract: 125,760. Farber, S. W. April 25, 1918. Supporting.-The base-piece of an electric-lamp support is constructed so that it can stand upon a desk or other support, or be fastened to a variety of obiects, and comprises two similar, preferably sheet metal, clamping-members 8, 9, each consisting of a flat rear part and a curved forward part, as shown in Fig. 2, and having two tongues 18, 19, Fig. 7, stamped out of the flat parts and bent at right-angles. The members 8, 9 are connected together by a spindle 21 passing through apertures in the tongues 18, 19 and kept in position by nuts 6. The spindle 21 carries a spring 12 having a rearwardly bent arch 17 pressing against the member 8 and rearwardly bent ends pressing against the member 9, so as to maintain the curved parts of the clamping- members together. The member 9 has a hole so that it can be hung upon a nail or the like, and the bottom of the base and the inside of the curved parts may be lined with cloth. The two elements 2, 5, Fig. 2, of the support may be hingedly connected by a screw, and the bottom of the element 5 is secured to a bridge-piece formed on stamping out the two bent-up tongues 18, 19 by tongues bent under and pressed against the bridge-piece.

Abstract: 1,146,393. Foamed cross-linked ethylene polymers. DYNAMIT NOBEL A.G. 14 Feb., 1967 [14 Feb., 1966], No. 7116/67. Headings C3C and C3P. A foamed cross-linked ethylene polymer is produced in flake form by a process comprising plasticizing at an elevated temperature an ethylene polymer or copolymer having a density of 0À915 to 0À965 g./c.c., kneading under pressure a mixture of the plasticized polymer and a peroxidic cross-linking agent at a temperature greater than the decomposition temperature of the cross-linking agent and thereafter suddenly releasing the pressure. Suitable cross-linking agents are dialkyl peroxides, e.g. dicumyl peroxide. The plasticization temperatures used for low density and high density polyethylene are 110 to 120 C. and 130 to 140 C. respectively. The cross-linking temperature should be preferably at least 20C. above the plasticization temperature. The quantity of peroxide to be used, may be 2À5-6% by weight for low density polyethylene and 3À5-6% by weight for high density polyethylene. The product is suitable for various insulating purposes.

Abstract: 793,632. Laminates. PRESSED STEEL CO., Ltd. March 15, 1956 [March 16, 1955], No. 7627/55. Class 140. Flexible laminated upholstery material consists of an outer covering 11 of leather, leather cloth, or a synthetic plastic coated fabric material, a layer 12 of a synthetic plastic or like foam material, and a fabric backing 13, e.g. calico, the whole being joined together by the application of heat and pressure at spaced zones where strips 14 of a thermoplastic or thermosetting material are located between the layers. The joining zones may follow a pattern. The strips or tapes, which may be of polyvinyl acetate or chloride, may be secured to the outer covering or backing or may be woven into the backing. The heating may be effected by steam, high-frequency induction, or electrical resistance elements. The foam padding may be polyvinyl chloride, polyurethane, or a polyester.

Title: Improvements in or relating to equipment for use with electrical resistance strain gauges
IPC: G01L1/22
Filed: 1943-11-29
Abstract: 586,268. Resistance measurements ; determining dimensions of materials. AUGHTIE, F. Nov. 29, 1943, No. 7678/46. Divided out of 586,229. [Class 37] Equipment for use with resistance strain gauges as described in Specification 586,229 is provided with means for calibrating the bridge circuits without actual straining of the gauge or gauges, after the bridge has been brought to initial balance. The main gauge M and temperature compensating gauge C form two arms of a Wheatstone bridge, the ratio arms of which consist of a series connection of three resistances R22, R23, R24. The resistance R23 is provided with a sliding contact whereby the bridge can be brought to initial balance within a certain range of values of the ratio M/C. Resistances R25, R26 in series are shunted across the resistance R23 to reduce the total resistance of the bridge. The galvanometer G is connected through a double-locking key K4, which in its central position reduces the sensitivity for protecting the galvanometer during preliminary adjustment of the bridge to initial balance, whilst the two locking positions give full sensitivity, one with the galvanometer reversed with respect to the other. Two resistances R37, R40, are connected in series by a switch S1 so as to produce a deflection which is very closely equal to that given by a known proportionate change of the strain gauge M. When a number of separate bridge circuits are employed, the resistance R37 is common to all the bridges, separate resistances R40 being introduced in the connections to the studs of the switch S1. Auxiliary resistances may be connected respectively in series and parallel with the main and compensating gauges or viceversa, whereby the bridge can be initially brought to balance with gauges of more unequal values than can be dealt with by the resistance R23 whilst retaining effective temperature compensation. More than one calibrating resistance may be provided together with associated switches, so that the bridge may be calibrated for more than one value of strain. Specification 565,462 also is referred to.

Abstract: 552,090. Resinous compositions. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 25,1941, No. 7981. Convention date, June 28, 1940. Drawings to Specification. [Class 2 (iii)] In bearing materials prepared from a base material, such as a fabric, bonded with a resinous binder, powdered graphite in a deflocculated state is evenly distributed throughout the bearing material by applying either to the base material prior to its impregnation with the resinous binder a liquid medium carrying graphite and a dispersing agent or by applying graphite and a dispersing agent to the resinous binder. A wetting agent may be used in addition to the dispersing agent. In one example, duck is dipped into an aqueous dispersion of graphite in a suspension of diglycol stearate containing a wetting agent, e.g. a sulphonated ester of a dicarboxylic acid or sodium alkyl naphthalene sulphonate, dried, impregnated with resinous binder and laminated under heat and pressure. In a second example, graphite and methyl abietate are added to a phenolic or other resin. The bearing material may include the wear-resisting materials described in Specification 480,530.
