Abstract: 1,126,261. Laminates; seaming non-metallic sheet material. CHAS. MACINTOSH & CO. Ltd. 28 April, 1967 [12 May, 1966], No. 21192/66. Headings B5K and B5N. A process for uniting two or more pieces of netting made from a material that cannot be heat-sealed comprises impregnating the material, at least in the areas to be united, with a heat-sealable thermoplastic material having a softening point lower than the destruction temperature of the material of the netting, interposing a strip of heat-sealable material that is compatible with the heat sealable impregnating material and also has a softening point below the destruction temperature of the material of the netting between two pieces of the impregnated netting that are to be joined and applying heat to the laminate so formed to cause the impregnating material to seal to the strip on each side thereof. The netting material may be a synthetic thermoplastic material, e.g. nylon, a natural textile material, e.g. wool or cotton, and may be a woven or knitted fabric. The heatsealable material used both as the impregnating material and the interposed strip is polyvinyl chloride and the material is heated under pressure to effect sealing using R.F. power. The process is particularly applicable to the manufacture of seams in clothing. A quantitative example is given.

Abstract: 516,837. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. July 20, 1938, No. 21556. Convention date, July 24, 1937. [Class 38 (iv)] Arcs.-A reversible motor 2 controls the position of a welding electrode 30 according to the voltage appearing across the welding arc, which voltage after rectification appears across a resistance 58 and is used to change the bias of one grid 43 of a double valve 37, the other grid 44 of which is bia'ssed constantly from a potentiometer 50, fed from a rectifier 34. A cathode resistance 47 is chosen so that the run of the anode currents is substantially constant, those currents being equal when the welding arc is of the desired length and one or other increasing when the arc varies. These anode currents are fed to saturating windings on inductances 21 which are associated with phase shifting circuits for energizing the grids of reversely connected discharge devices 6, 7 in circuit with the motor 2. Normally each device 6, 7 conducts for half a positive half cycle and the motor remains stationary. Upon change of saturation of the inductances 21, one device conducts for a longer period and the other for a shorter period, so causing the motor to run in a determined direction. A self-saturating inductance 62 keeps the motor current low when the devices 6, 7 conduct equally.
