Title: Electrical epilator
IPC: A61B18/14
Filed: 1962-06-05
Abstract: 936,947. Depilatory appliances. R. TAPPER. June 5, 1962, No. 21650/62. Class 81 (2). The needle of an electrical epilator is resiliently mounted so as to be slidable axially under excessive pressure. By this means although the needle will enter a hair follicle without difficulty, it will yield if the operator inadvertently presses it against the skin. In one preferred form the needle 8 is mounted in a holder 7 which is slidable within a metal tube 5a against a helical spring 6. The needle carrier 5 is screwed into an insulating block 3 to which forceps blades 1, 2 are attached and these may be connected in the operating circuit by a contact 11 which is closed, to energize the needle, when the blades are squeezed together. This completes the supply circuit to the assembly 17 which incorporates either a multivibrator or a phaseshift oscillator, using transistors, designed to give an approximately square-wave output of the order of one cycle per second. The same type of resiliently mounted needle may be used in a self-contained, battery-energized epilator.

Title: Improvements in sheet gripping mechanism of printing machines
IPC: B41F21/10
Filed: 1923-08-28
Abstract: 226,584. Evans, A. B. Aug. 28, 1923. Gripper mechanism.-The grippers of impression cylinders, feed chains, &c. of printing-machines are each constructed of two parts a, c, of which the part c forming the gripper proper is freely mounted on the gripper shaft b and the part a is connected, to the shaft b by a clamp a<3> actuated by a screw a<2>. Between the two parts a, c is arranged a flat spring d, Fig. 1, or a coiled spring e, Fig. 2, the strength of which is chosen in accordance with the pressure to be inserted on the sheet. The part a is formed with a projection, a<3> against which the underside of the gripper normally abuts. In setting the grippers on the shaft b, this shaft is moved to its closed position and each clamp a<8> is moved to free the part a. A thin piece of metal is inserted between the projection a<3> and the under side c<3> of the gripper, and the part a moved to cause the gripper c to engage the impression cylinder or the like. The clamp a<8> is then tightened, and the metal removed between the parts a<3>, c<3>, thereby causing the gripper to press on its seat with a pressure depending on the strength of the spring d or e. The pressure of the grippers on the sheets is released by the projections a<3> acting on the surface c<3> when the shaft b is rotated clockwise. In modifications a helical spring in compression is arranged between projections on the upper sides of the parts a, c; or a helical spring may surround the shaft b and be connected to the part c and to an adjustable collar fixed on the shaft b.

Abstract: Curable epoxy resin compositions are prepared by treating polyepoxides with an equilibrium mixture prepared by reaction of boric acid or boron trioxide with hydrofluoric acid which mixture is added either alone, or in the presence of solvents or carriers for the catalyst and reaction retardants.  The polyepoxide may already have been compounded with reactive monomers such as monoepoxides, heterocyclic compounds of oxygen, and unsaturated monomers; thermoplastic or thermoreactive resins; solvents; plasticizers; fillers; colorants; and/ or other additives. Reaction retardants specified are ammonia and its salts; amines; amides of carboxylic and carbonic acids; amino acids; lactams; and cyano and nitrogenous heterocyclic compounds.  The catalytic equilibrium mixtures are preferably added together with organic acids or metal soaps to control the ionic catalyst reaction.  The compositions are suitable for use as coating, laminating, impregnating, adhesive and cable jointing compositions.  Epoxy resin foams are made by adding a low-boiling solvent to the curable composition before curing.ALSO:Coating compositions comprising an epoxy resin, an equilibrium mixture obtained by reacting boric acid or boron trioxide and hydrofluoric acid and, optionally, reactive monomers, macromolecules, solvents, plasticisers, fillers, colorants and retardants (see Division C3) may be applied by spraying, rolling, brushing or dipping or by means of a fluidised bed to surfaces of, e.g. metal.

Patent GB-1060407-A (GB)
Title: Improvements in or relating to methods of and apparatus for cracking hydrocarbons
IPC: C10G9/00
Filed: 1964-05-29
Abstract: A method of cracking a hydrocarbon to form hydrocarbon products, e.g. C1-C4 hydrocarbons, comprises subjecting a hydrocarbon fuel to combustion in the presence of oxygen to produce a combustion gas at elevated temperature and pressure, mixing the combustion gas thus formed with the hydrocarbon to be cracked to cause cracking of the hydrocarbon and form a gaseous mixture including said hydrocarbon products, the gaseous mixture having a temperature less than that of the combustion gas, thereafter driving a gas-turbine with the gaseous mixture which undergoes adiabatic expansion and cooling, and thereafter separating the hydrocarbon products from the gaseous mixture after the latter has been discharged from the turbine. The preferred hydrocarbon starting material is naphtha, which may be supplied in admixture with superheated steam.  The combustion gas may attain temperatures of 1300 DEG  to 1500 DEG  C. and the hydrocarbon to be cracked is added in amounts sufficient to maintain the gaseous mixture at 700 DEG  to 800 DEG  C.  Heat may be extracted from the gaseous mixture discharged from the gas turbine.  In an example in which naphtha is cracked, the product contains 29% ethylene, 10% propylene, 32% methane, and smaller amounts of hydrogen, ethane, propane, butane, butylene and butadiene.
