Title: Stitching device for rotary printing machines
Inventor: PILS WALTER
IPC: B42B4/02
Filed: 1966-11-11
Abstract: 1,114,228. Stapling. PLAMAG PLAUENER DRUCKMASCHINENWERK VEB. 11 Nov., 1966, No. 50678/66. Heading B6H. [Also in Division B4] In a stitching device for rotary printing machines a wire piece is transferred to a rotating stitching cylinder carrying a cam-controlled driver plunger which drives the staple from a matrix into the product to be stitched, the matrix being radially movable in a guide of the stitching cylinder and co-operating with a punch pivotally mounted on the cylinder which punch during the formation of a staple from a wire piece held by the punch, enters the matrix wheel, is moved radially and is then removed to leave the way free for the driver plunger to drive the staple from the matrix into the product. Stitching cylinder 1 carries matrix 5 movable radially in guide 2 and provided with receiving grooves 3 for wire piece 4 to be shaped into the staple. Matrix 5 is moved by camcontrolled shaft 6 and lever 7. Toggle-lever-like staple support 8 is pivotally mounted at 9 on matrix 5 and is guided during radial movement of matrix 6 by a cam surface 12 such that it engages between the staple legs and against the staple back. A driver plunger 16 is mounted in guide 15 to be radially movable by camcontrolled shaft 17 and lever 18. Plunger 16 engages in the receiving grooves 3 of matrix 5 and has a groove 19 for the reception of the back of the staple. A punch 20 is pivoted about bolt 21 to transfer a wire piece 4 from the cutting device (not shown) to stitching cylinder 1. Punch 20 is held by spring bolt 22 such that wire 4 received in mouth 25 lies in a plane common with the receiving grooves 3 of matrix 5. When plunger 16 moves radially to insert a staple into a product, nose 23 pivots punch 20 out of the plunger path by engaging surface 24. In use, a wire piece 4 taken from a cutting device by punch 20 is held in mouth 25. Matrix 5 moves radially and slides over the head of punch 20 thereby pushing wire piece 4 into grooves 3 to form a U-shaped staple. Simultaneously support 8, guided by cam 12, moves around the head of punch 20 until its free end lies in the conveying path of the staple. At the stitching position where cylinder 1 meets a counter cylinder carrying a closer plate plunger 16 moves radially, trips punch 20 out of its path and engages the staple, now supported by matrix 5 and support 8 bearing on the back of the staple. As cylinder 1 turns and the staple is pushed into the product matrix 5 and support 8 are withdrawn into the cylinder, releasing the staple.

Filed: 1971-11-02
Abstract: 1365953 Fuel injection pumps ROBERT BOSCH GmbH 2 Nov 1971 [3 Nov 1970] 50822/71 Heading F1A A fuel injection pump having a reciprocating and rotating pumping piston 1 and a shuttle spill valve 14 operating on the hydraulic stop principle is adapted for use with an engine in which the cylinders receive fuel at irregular intervals, e.g. a six cylinder V-engine. The piston 1 is reciprocated by a cam 35 which co-operates with rollers 38, the cam profile 39 having unequally spaced lobes. Each time the piston 1 performs a pumping stroke, fuel is pumped from a chamber 19 by an auxiliary piston 18 thereby to displace the shuttle valve 14. This displacement opens a spill passage 15a, 15b to terminate delivery to whichever of delivery passages 12 is in communication with a groove 11 in the periphery of the piston 1. The return stroke of the shuttle 14 is effected by a spring 25 which forces the liquid which produced its forward stroke through a throttled passage 26. Because of the irregular intervals between successive strokes the throttled passage 26 is closed during the time between at least some consecutive strokes. This closure of the passage 26 delays the return stroke of the shuttle. Closure is effected by the piston 18 or the piston 1, Figs.3 and 4 (not shown) at least while the cam causes the pistons to dwell at the end of certain of the compression or suction strokes.

Abstract: 1,037,538. Rectifying. BROOKHIRST IGRANIC Ltd. Dec. 24, 1963 [Dec. 31, 1962], No. 50888/63. Heading H2F. Rectifying circuit RN comprising diodes 4, 5, 6 and series pairs of thyristors 1, 2, 3 are controlled by identical control circuits 8, 10, 12. The circuit 8 has a unijunction transistor oscillator which is arranged to trigger the pilot thyristor SCR when capacitor C1 is charged to the critical value. The rate of charging of capacitor C1 is controlled by transistor T1 and input control voltage 18. This control voltage may be derived through a potentiometer from the stabilized supply VR to the control circuits. The pilot thyristor is in the primary circuit of transformer PLT, and when it is triggered voltage pulses are induced in each secondary to fire the main thyristors 1. The charging of capacitor C1 is synchronized to the supply by transistor T2 which shunts the capacitor C1 when made conducting by a voltage from secondary S1 of transformer PT. So that the firing circuit may permit firing over 240 degrees (to give the maximum range of output from the three phase rectifier RN) the circuit: diode D2; resistor R3; capacitor C2 is provided to delay turn on the transistor T2 beyond the end of the 180 degrees period which its single phase supply would otherwise permit.

Abstract: 1,212,214. Hydraulic reciprocating motors. SOC. DES AUTOMOBILES SIMCA. Nov.23, 1967 [Nov.25, 1966], No.53295/67. Heading F1A. A hydraulic motor comprises a double-acting piston 2, Fig. 1, controlled by an electromagneticallyactuated distributer 9 biased into a neutral position 9b by springs 14, 15. From the rest position shown of the motor, depression of a manual starting switch (Ma), Fig.2 (not shown), energizes electromagnet Aresultingin rightward movement of the distributer and consequent connection of the cylinder spaces 5 and 6 respectively to a pressurized fluid supply line 10 and a return line 11. Moreover, the moving distributer, via a lever 23, opens switch A 2  and closes switch A 1  which thereafter maintains the electromagnet A energized so that the manual starting switch (Ma) can be released. The eventual rightward movement of the piston 2 causes a cam 4 to close switch FCO, open switch FC 1  and then close switch FC 2 . Opening of switch FC 1  deenergizes electromagnet A and the springs 14, 15 return the distributer to its neutral position shown whereat the switch A 2  is closed, so that the electromagnet B is energized through closed switches FC 2  and A 2  . The distributer is then moved leftwards and reverses the supply and return connections to the cylinder and, via a lever 22, opens switch B 2  and closes switch B 1 . The closed switch B 1  together with closed switches FC o  and A 2  maintain the electromagnet B energized since the switch FC 2  is opened shortly after commencement of the leftward movement of the piston 2. This movement continues until switch FCO is again opened to de-energize electromagnet B and allow the distributer to return to the neutral position. Thus the machine has completed one cycle after which its operation ceases unless a re-cycling switch (Ca) has been closed during the first cycle.
