Abstract: 697,220. Automatic arc-welding control systems. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. April 7, 1952, No. 8812/52. Class 38 (iv). In an automatic electric arc-welding machine the electrodes of which are fed by a D.C. motor, the motor armature is supplied in series with an adjustable resistance from the arc voltage and the motor field is separately excited and works under saturation conditions. To maintain constant the voltage between a D.C. welding electrode 1 and a workpiece 2, the voltage is applied to the armature of a D.C. motor 5 feeding the electrode automatically. Resistance 8 which limits motor speed on starting, before the arc is struck, is automatically short-circuited when the arc is struck, by a contact 9 of a relay (not shown) responsive to welding current. Resistance 7 is adjusted to give a suitable speed of feed. The motor field has a separately excited winding 6 the effect of supply voltage variations to which are minimized by operating the field at saturation. In a modification, Fig. 2 (not shown), an A.C. arc is controlled, the motor being supplied through a transformer and rectifier.

Title: Tension sensing and regulating apparatus
IPC: B65H59/40
Filed: 1973-02-23
Abstract: 1429271 Feeding webs E I DU PONT DE NEMOURS & CO 23 Feb 1973 [25 Feb 1972] 9042/73 Heading B8R [Also in Divisions G1 D1 and G3] The tension in a rope R, yarn Y, web or similar flexible material is sensed by guiding the material around at least one guide on a member 28 or 102 which is movable angularly about a pivot axis which passes through the path of the material, the or each guide being between the pivot axis and the single end of the member 28 or 102, the movement of the member 28 or 102 being sensed either pneumatically (as in Fig. 1) or photo-electrically (as in Fig. 3) and a signal applied to a device for regulating the tension in the material thus maintaining it at a desired preset value. In the embodiment shown in Fig. 1, a rope R passes around a guide roller 24 and through guide eyelets 34 (only one shown) in a beam 28 pivotable about flexure pivots 30 at one end of the beam, a bellows 40 exerting a preset pneumatic force (corresponding to a desired tension) on the other end of the beam. A bolt 54 and nuts 58, 58<SP>1</SP> limit movement of the beam relative to frame 27. A control valve 60, mounted on the frame and provided with a zero-point adjusting screw 62, is supplied with air on line 64, the back pressure on line 64 varying with the position of the beam 28, and is coupled to a pneumatic servo unit 20 which controls the angular position of a tension regulating device 10 comprising rods 11, 11<SP>1</SP> around which the rope passes in an S-shaped path. Any deviation of the tension from the desired value is thus automatically corrected by the device 10. An alternative embodiment shown in Figs. 3 and 4 comprises a feed roller 100 which feeds a yarn Yi, Yo past a guide pin 106 mounted on a beam 102 supported on a knife-edge 104. Variations in tension of the yarn cause the beam to pivot against counterweight 108, and an extension 109 then blocks, to a degree proportionate to the beam movement, the light path between a light source 111 and a photo-cell 112. The output from the photo-cell 112 is fed to a control system 114 linked to a motor 138. The motor 138 controls the rate and direction of rotation of the casing of an A.C. synchronous primary drive motor 120 for the feed roller 100, thereby controlling the speed of the feed roller and maintaining the tension in the yarn Yi, Yo.

Abstract: 1293657 Opening film cartridges EASTMAN KODAK CO 26 Feb 1970 [26 Feb 1969] 9243/70 Heading G2A A means for breaking open a frangible film cartridge to remove an exposed roll or film therefrom is a modification of that disclosed in Specification 1149992, and is operated by a handle. The cartridge is inserted into a support, Fig.2 (not shown), until a pair of holders (46) pivot on their mountings (44) until spindles (48) thereon engage opposite ends of a take-up spool 16. By raising a handle 72 clockwise about an axis 64, from the position shown in full lines through the successive positions shown in broken lines, until it comes up against a stop 76, the cartridge is pivoted about the spindles (48) until an edge thereof engages against a knife edge (58), Fig.4 (not shown). This ruptures the cartridge and, if it is formed from two halves which have been sealed together, causes it to split along the seal. The broken parts fall away, leaving the spool still held by the spindles (48). An arm 74 hangs downwards from the support, and as it moves through the dotted line position the arm rides over the surface of the spool. As the handle is rotated back to its original position, arm 74 engages the spool, and pushes it free of the  spindles, and into a collector. The handle may be operated by an electric motor.
