Title: Bending machine for bars wires and sections
IPC: B21D11/12
Filed: 1971-05-26
Abstract: 1344545 Angular bending C U PEDDING- HAUS 26 May 1971 [1 June 1970] 17353/71 Addition to 1286865 Heading B3G [Also in Division G3] A bending machine for metal bars, wires or sections as claimed in Specification 1,286,865 characterized by bending angle circuits corresponding respectively to a plurality of predetermined bending angles which are connected at choice in a programme storage circuit having a number of storage locations exceeding the number of the predetermined bending angles so that each storage location is connected to a bending angle circuit, which programme storage circuit switches progressively at each switching step by one storage location and which in its turn is switched over to a control circuit of the drive for the bending machine, in which switch position said programme storage circuit switches progressively after each bending to the next storage location. The circuit shown in Fig. 1, consists of three bending circuits each of which can be set to one of the angles through which the work is to be bent, e.g. 45, 90 or 180 degrees. All the storage circuits 32-37 are connected to all the bending circuits (although shown only connected to A). Initially each storage circuit is set to the angle to be bent at that position. This is done by setting switches 61, 62 to the dotted position and closing one of manual switches 57, 58 or 59, each associated with one of the bending circuits. One of the the three relays 53 associated with each storage circuit then locks on so presenting a supply to the storage circuit and a connection to the bending circuit appropriate to that storage circuit. Stepping counter 49 then moves to the next storage circuit which is set by one of the switches 57-59 to the appropriate bending angle. After the storage circuits are set manual switches 61, 62 are set to the full line position and are then under the control of cam operated switches 46, 55 carried on the periphery of the bending table. At the start of each bending cycle, switch 56 at the zero position of the bending plate steps counter 49 to connect the supply through the storage circuit to the appropriate bending circuit which energizes a motor to drive the bending plate. As the plate rotates a pulse is produced as each bending angle is reached thus stepping relay 46 until the angle corresponds to that connected to the relay contacts 43 by the appropriate bending circuit. The relay 47 is then energized to stop the bending motor and allow the bending plate to return to its zero position.

Abstract: 499,277. Rolling screw threads. WOLSELEY MOTORS, Ltd., and GOULD, G. June 11, 1938, No. 17380. [Class 83 (iv)] A revolving rod 13 is screw-threaded by moving it into contact within a pair of threaded rolls 1, 2 freely rotatable in a bracket 5, adjustably pivoted at 7 on a holder 14, which may be pushed in by the feed slide of an automatic machine. A screw 9 adjusts the degree of pivoting of the bracket 5 in co-operation with a spring 11 which allows the rolls to float. The roll pass may be adjusted by rotating the eccentric shaft 3 of the top roll, the shaft then being locked in position by a pin 18 which holds in position the quadrant 16 fixed on the shaft 3. Axial floating movement of the roll carrier is provided by spring washers 20 on the pin 7 located between the carrier lugs 8 and the holder 6. The top roll has additional axial floating movement by spring washer 19 (not shown) on its shaft. The length of the threaded part of the rolls is approximately equal to the length of the axial thread to be formed so that no traverse of the rolls along the work bar is necessary.

Title: A method of reproducing wood graining
IPC: B41M3/06
Filed: 1920-06-25
Abstract: 169,515. Haddan, A. J. H., (National Cash Register Co.). June 25, 1920. Printing-processes.-Imitation wood graining is produced on surfaces by a process in which a specimen of natural wood is photographed, the design etched in intaglio form on metal, and thence transferred by means of stain and an elastic roller to the surface. A half-tone Rembrandt screen is preferably used in making a print on carbon tissue, but other forms may be used such as straight-line and wave-line screens. The effect of the screen is to break up the etched area into small cells of varying depth. The carbon tissue is soaked in aqueous alcohol and then placed face downwards on a metal plate or cylinder. When the paper backing and soluble gelatine have been removed with warm water, a deposit of insoluble .gelatine or resist is left on the metal. When dry, the metal is etched with ferric chloride. The etched parts are then filled with stain. The action of the soft roller destroys the outlines of the small etched areas or cells of the metal. The grained surface may be brushed over with a soft blending-brush.

Abstract: 515,903. Valve generating circuits. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. June 15, 1938, No. 17822. Convention date, June 15, 1937. [Class 40 (v)] In a back coupled oscillator in which the rate of flow through a grid controlled electron discharge valve is periodically changed by negatively charging a condenser in the grid circuit through a rectifier and an inductance reactively coupled with the valve anode, a further rectifier is connected in parallel with the condenser to ensure that the condenser is always charged to the same potential. The condenser 11 is charged slowly from battery 13 through resistance 14 and anode current flows at a slowly increasing rate. When a synchronizing pulse is received on an additional grid of valve 10 or when the voltage across the condenser exceeds that across coil 12 the condenser 11 and the whole of the magnetic energy of coil 16 discharges rapidly through rectifier 15 so that condenser 11 is charged in the opposite sense, and the condenser charge is then again built up slowly from battery 13 for the cycle to repeat. Rectifier 18 and battery 19 ensure that the negative voltage on condenser 11 is always the same and equals the steady voltage of battery 19. A saw tooth potential is produced across condenser 11 and a saw tooth current flows in coil 16 which may be a deflecting coil of a cathode-ray tube. Specification 461,325 is referred to.
