Title: Improvements relating to draw benches
IPC: B21C19/00
Filed: 1937-02-20
Abstract: 489,388. Drawing. ACCLES & POLLOCK, Ltd., and HACKETT, G. Feb. 20,1937, No. 5115. [Class 83 (iv)] A device for drawing metal tubes, rods, strips, or the like through the die of a drawbench comprises a carriage travelling horizontally along the bed of the machine, gripper jaws in one end of the carriage, a hook pivoted at the other end of the carriage and adapted to engage the drawbench chain, means actuated by the hook for closing the jaws on the work, and a catch for holding the hook out of action. In a machine wherein two benches are mounted in parallel relation, each workpiece r is drawn through a die a by a carriage b having wedgeshaped jaws g sliding in inclined ways f and a hook adapted to engage a drawing chain m. A catch t holds the hook j in the raised position. The jaws g are moved into gripping engagement with the work by a lever h which is rocked on downward movement of the hook j through an arm n and a spring p engaging a nut q on a rod o. At the end of the return movement of the carriage b the catch t is released upon engagement with a hand-operated removable abutment v, and the hook j falls into engagement with the chain, the jaws g thereby being moved into gripping engagement with the work. The tension of the chain causes the hook to be moved again to the raised position, the adjacent parts of the chain being raised with it, and the catch t again engages the hook to maintain it in raised position. When the work leaves the die at the end of the operation, the tension in the chain is relieved, and the chain falls free of the hook. Disengagement is ensured by projections x adapted to ride up inclined portions of the track. Return movement of the carriage is effected by the descent of a two-part weight 11, 12, the part 11 engaging an abutment 16 towards the end of the descent so that the movement is completed under the action of the weight 12 only. The weight 12 is adjustably secured to a rod 13 by a spring-pressed pawl 19 co-operating with a series of recesses 18. A relatively short movement of the weight produces the required return movement through a rope 5, a pulley 3, a large pulley 2 and a rope y connected to the lever h. Lateral spring-pressed friction pieces bring the carriage to rest without shock.

Abstract: 211,705. Zweigbergk, T. Feb. 22, 1923. Master control systems; control systems.- Motor control systems of the follow-up kind described in Specification 175,877 are adapted for multiple - unit control by associating each unit secondary or follow up controller with a set of relays solely responsive to current passing between the primary or master controller and the particular secondary controller of the respective unit. The Figure shows two secondary controllers 51, 57 operated respectively by auxiliary motors 88, 89 in such a manner as to repeat the movements of a single master controller 92. The conductors 46 - - 50 which connect, for example the secondary controller 51 to the train-wires 41 - - 45 pass through normally open switches 68 - - 72 adapted to be closed bv the energization of relay coils 58 - - 62. When the master controller is turned to any position, the corresponding relay coil is energized to complete a circuit through the coil of the motor - starting and stopping relay 90. The motor 88 runs until the follow-up movement has been accomplished, whereupon the coil of the relay 90 is cut out. The conductors 52 - - 56 leading to the secondary controller 57 are similarly arranged. In systems with a number of secondary controllers, one of these may be arranged for direct connections without relays, and one or more of the relays may be omitted from the set associated with a particular controller.

Title: Electrolytic reductive coupling of olefinic reactants
IPC: C25B3/29
Filed: 1975-02-07
Abstract: 1477076 Electrolytic reductive coupling reactions MONSANTO CO 7 Feb 1975 [11 Feb 1974 (2)] 5221/75 Heading C2C [Also in Division C7] One or more olefinic reactants is/are reductively coupled in an aqueous electrolysis medium into which interfering amounts of heavy metal pass during electrolysis, there being added to the medium sufficient heavy metal sequesterant during electrolysis to maintain excess free sequesterant therein, and the concentration of heavy metal being maintained not in excess of 50 mMol/l. A "heavy metal" has an s.g. above 4. e.g. Fe, Cd, Pb, Zn, Ni, Hg, Mn, Co, Cu, Cr, Ti, Tl, V, Mo, Ru, Sb, Bi, Pt and Pd, and may derive from electrode corrosion or other parts of the apparatus used. Specified reactants have formula R 2 C = CRX where X is CN, CONR 2  or COOR<SP>1</SP> and R is H or R<SP>1</SP>, R<SP>1</SP> being C 1-4  alkyl. Such reactants may be dispersed as an organic phase in an aqueous medium containing conventional quaternary ammonium ions and conducting salts, and be electrolysed in a divided (with cationic membrane) or undivided cell with mono- or bipolar electrodes, either continuously or batchwise. Reactant recirculation is possible, with removal of products and heavy metal contaminants, and addition of fresh reactants and sequesterant. Specified sequesterants are aminopolycarboxylic acids, e.g. EDTA and N-hydroxyethyl EDTA, α- hydroxycarboxylic acids, 3,5-disulphopyrocatechol, and pyridine compounds. Their action may be augmented by adding a boric or condensed phosphoric acid or alkali metal salt thereof. The heavy metal concentration may be maintained by purging a portion of the reactants and replacing it with one of lower metal content, or by removing, e.g. by precipitation, heavy metal contained in a recycle stream. An electrolyte pH of 2-12, preferably at least 7; a temperature of 5-75 C., or more under pressure; a current density of 1-150 A/dm<SP>2</SP>; and flowing electrolyte are specified.

Title: Improvements relating to the mounting of card clothing on the drums or rolls of carding or like machines
IPC: D01G15/84
Filed: 1943-04-05
Abstract: 565,126. Carding engines. KARDBESLAG FABRIKS AKTIEBOLAGET. April 5, 1943, No. 5443. Convention date, April 27, 1942. [Class 120 (i)] A machine for mounting fillets of card clothing on drums or rolls of carding machines having a movable member arranged in the path of the fillet from a braking device to the drum or roll and actuated by the tension on the fillet and by an external load, such as a spring, and wherein the movable member is adapted on a variation in the tension in the fillet to actuate the braking device so as to maintain a constant tension is characterised in that the braking device and the movable member are constructed and arranged so as to act upon the back of the fillet exclusively. As shown, the fillet is led by guides around braking drums 8, 9, Fig. 1, and from the drum 8 passes around a roller 22, Fig. 2, mounted on an arm 21 secured to a shaft 15 located between the end plates 1, 2 of the apparatus ; a part of the shaft is threaded to engage threads 14 on the inner face of a sleeve 12 fixed to the plate 1 by a flange 18 and the drum 8 is loosely mounted on the sleeve and the drum 9 on the shaft 15. A friction ring 16 is disposed between the adjacent faces of the drum and a similar ring 17 between the drum 8 and the flange 18 of the sleeve and should the tension on the fillet tend to vary, the arm 21 moves to rotate the shaft 15 and so move the drum 9 to vary the pressure between the drums and the friction rings to alter the braking effect and keep the tension constant. The initial pressure between the braking surfaces is adjustable by a nut 19 screwing on the end of the shaft 15 against the roller 9. The arm 21 carries a guide bar 25 spaced therefrom and parallel thereto for a slide block 26 engaging a slotted link 31 adjustable along a flatted guide 35 by a screw and hand lever 39 ; the block 26 is held against the bar 25 by a cord 28 connected to a pulley 29 on a spring drum and by moving the link 31 along the guide 35, the pressure of the block on the bar 25 on the arm 21 may be varied to give the desired tension on the fillet, such tension being indicated by a pointer 42 on the link reading against a scale on the guide 35. The whole device is mounted on a pair of guide rods 5, 6, disposed parallel to the drum being covered with the fillet, by claws 3, 4 so as to be readily removable from the rods. In a modification, a two-armed lever is secured on the shaft 15, one arm carrying the roller 22 while one end of the wire 28 is secured to the other arm, the other end of the wire 28 being secured to a disc having a spiral groove mounted on the spring drum. The end of the lever carrying the roller 22 is formed with an extension circular about the shaft 15 on which may be mounted a number of guide rollers in order that the turning moment due to the tension in the fillet about the shaft 15 may be maintained approximately constant.
