Title: Electrically operated, fluid actuated mechanism for controlling the magnitude of a quantity
IPC: G05B11/50
Filed: 1950-06-19
Abstract: 699,803. Automatic control systems. BROIDA, V. June 19, 1950, No. 15309/50 Class 38 (iv). In a system for automatically controlling a variable in which deviations in opposite senses influence different normally closed electrodynamically-operated inlet and outlet valves controlling a fluid pressure servomotor correcting the variable, an opposing effect on the valves is produced by an electric regulator responsive to the fluid pressure. In Fig. 1 deviations of a variable are caused to move the slider 30 of a potentiometer 31 to upset the balance of an A.C. bridge circuit energizing windings 19, 20 of a two-way relay 21 so that a contact 22 or 23 is engaged to energize a solenoid 25 or 24 to open a valve 4 or a valve 3 and thus decrease or increase the pressure in a chamber 2 by connecting it through a pipe 6 to atmosphere or through a pipe 5 to a source of constant fluid pressure. The pressure in chamber 2 is thus varied until a bellows 9 associated with it adjusts the slider 12 of a potentiometer 14 to re-balance the bridge circuit. The changes in pressure of chamber 2 control through a pipe 7 a fluid pressure servomotor (not shown) correcting deviations of the variable.
Patent GB-982105-A (GB)
Title: Artificial leather
IPC: B32B27/00
Filed: 1963-04-18
Abstract: Perforated flat strip-like artificial leather is produced by coating an open or wide-meshed fibre structure, on one or both sides, with a thermoplastic material, embossed and in the same operation, embossed so deeply in spots that knob-like projections are formed and these projections are later cut off or ground off. The embossing may be carried out on an embossing roller which may comprise, in addition to the pattern to be reproduced, mandrels and/or stamps for producing the projections.  The counter roller to the embossing roller is of rubber.  One side of the fibre structure may be coated, the coating embossed, the knob-like projections removed and then the second side of the fibre structure coated.  The open fibre-structure may be a net, screen, loose fleece, knitted fabric, or woven fabric having in warp and weft 2-12 threads per centimetre of thickness 20-3000 denier, e.g. 5 threads per centimetre of thickness 1000-2000 denier. The open fibre structure may comprise natural or synthetic fibres, e.g. regenerated cellulose, polyamides, polyesters such as polyethylene glycol terephthalate, polyacrylonitrile, polycarbonate or any homopolymer or copolymer commonly employed in the manufacture of fibres.  Both sides of the open-fibre structure may be coated, but only one side is embossed.  The perforations in the thermoplastic coating may have positions determined by the embossed pattern.  The perforations may have round, oval, angular, star-shape or other geometric shapes.  The artificial leather may be welded, in parts and preferably along the edges, to artificial leather and/or uncoated textile structures, preferably by means of high frequency welding. The example describes the perforation of net fabric of multifilament polyester threads having a polyvinyl chloride foil on the side and a polyvinyl chloride coating on the other.

Filed: 1932-06-01
Abstract: 384,910. Controlling change-speed gearing ; operating clutches. GMEINDER & CO., GES., Mosbach, Baden, Germany. June 1, 1932, No. 15497. Convention date, June 20, 1931. [Class 80 (ii).] Friction clutches such as A, B, B<1>, Fig. 4, in change-speed gearing are operated separately by linkages in each of which is a spring C which is initially tensioned to the degree for engaging the clutch, so that a small displacement of an actuating member w is sufficient. The three balls w shown are operated selectively by a ramp v which travels on a hand-operated screw u. Each ball w rests on a slidable casing f which envelops one of the springs C and is closed by a cap f<2>. Between each spring C and cap f<2> is a head T upon a rod f<3> through which, and through a lever r, thrust is transmitted to engage the selected clutch. When a ball w is depressed, a counter-abutment cap f<2> moves away from under one abutment T of the spring so that the full operative pressure is transmitted from the other abutment, the top end of the casing f, to the clutch lever r. In a form shown in Fig. 2, manual thrust is applied to a rod g and is passed on to a shaft k operating two clutches by a box f containing two springs D, E initially compressed. Each spring abuts at one end against an end of the box and at the other against one of two washers f between which is a counter-abutment f<2> on the box and also a head g<1> on the rod g. If the rod g is displaced a short distance to the right, the head g<1> pushes the right washer f<1> away from the counter.abutment f<2> so that the full thrust of the spring E is transmitted to the box, the spring D remaining inoperative.
