Filed: 1959-08-18
Abstract: 932,473. Printing-machines. MURRAY CURVEX PRINTING Ltd. Aug. 17, 1960 [Aug. 18, 1959], No. 28140/59. Classes 100 (1) and 100 (2). A machine for printing or decorating articles having a slight curvature such as plates comprises an off-set resilient pad 4 movable between a flat inked plate 17 having a design in cameo and a printing station, a suction head 3 for moving the plates between a stacking station and the printing station, and pneumatically controlled means for effecting these movements automatically in timed relation so that a fresh plate to be printed is always positioned at the printing station when the pad 4 reaches this station. The suction head 3 and the pad 4 are attached to the piston rods of double-acting power cylinders 7, 6 respectively, which are supported on arms 9, 8 clamped to an oscillatable column 1. In an embodiment, not shown, the off-set pad 4 may be replaced by a resilient pad bearing a design in cameo, said pad being inked by a flat plate or a porous pad. Inking.-A power cylinder 16 has its piston connected to a cross-head 18 which is linked to the column 1 by a work arm 19 and connected to inking and doctoring means 20. The inking member 23 is pivotally mounted on an arm 24 and has a downwardly directed surface 25 above the design plate 17. An inclined doctor blade 26 bolted to member 23 has its lower edge parallel to the surface of the plate 17. Ink in the reservoir formed between the plate 17 and surface 25 is spread over the plate during a forward stroke of the crosshead and during its return stroke pressure is applied to overcome the spring 28 and urge the blade 26 into contact with the plate. Feeding.-As the head 3 is lowered a suction cup 57 engages a plate in a stack located against pins 14 and moves a piston 59 within a cylinder 58 to compress a spring 58a and exhaust the cylinder around the edge of the cup seal 59a and through a vent. Upward movement of the piston rod 60 then permits movement of the piston 59 until the partial vacuum formed is sufficient to lift the uppermost plate. The arm 9 is then swung to the printing position, the rod 60 lowered, and the article released, release being assisted by a positive stream of exhaust air. Operation.-The machine is operated by a pneumatic control circuit, Fig. 4 (not shown), comprising valves and restrictors which control the actuation of the arms 8, 9 the cylinders 6, 7, the cylinder 16 and head 18, and the pressure applied to the spring 28 to lower the doctor blade. According to the Provisional Specification the stationary table 13 may be replaced by a rotatable turret.

Abstract: 988,726. Winding lay-outs for dynamo-electric machines. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 19, 1963 [July 24, 1962], No. 28381/62. Heading H2A. In a system of pole-changing by poleamplitude modulation effected by applying a single pole-amplitude modulation wave to the three-phase winding as a whole, and in which neither the unmodulated pole-number nor number of cycles of the modulation wave (which has an odd number of cycles) is three or a multiple thereof, the unwanted resultant pole number is either eliminated by chording or ignored, and the winding is arranged to have three slots per pole per phase (or a multiple thereof) and reversing substantially one half of the coils of each phase in such a way as to provide a single wave extending over the winding as a whole whilst preserving the balance of each phase about a neutral line for the phase. The 4-pole, 36-slot winding shown in Fig. 1 is modulated by a single cycle X-X to produce 6-pole operation. The conductors under the line X-X are reversed on modulation. Simply reversing half of the winding, e.g. slots 19-36, provides the desired modulated pole-number of six, but leaves the winding unbalanced. Fig. 2 shows the vector positions of phase A slots with respect to the 6-pole operation for which the slots are spaced by 30 degrees. Reversal about the neutral line by reversing slots 19-36 is shown by ringing the slots reversed. Fig. 3 shows the vector-positions of the phase " C " slots, and shows that simply reversing half the winding does not reverse the correct vectorially placed slots. Thus, coil 33 is not reversed, but coil 15 is to produce a phase-winding which is balanced about its own neutral axis. Similar considerations apply to the remaining phase. A series-parallel winding arrangement to produce the desired effect is shown in Fig. 5 (not shown). The invention is described with reference to other pole numbers. Specifications 900,600, 926,101 and 968,988 are referred to.

Title: Sheet feeding machines
IPC: B65H3/08
Filed: 1926-11-11
Abstract: 270,572. Aldrich, L. K. Nov. 11, 1926. Sheet-separators.-Sheets are fed to printing, ruling, folding, and like machines by means of oscillating suction arms 14 which separate the top sheet from the pile 5 and buckle it slightly while raising it to a wheel 1 formed with suction ports 8, Fig. 8. The wheel 1 can be rotated continuously by driving its shaft 2 by a detachable crankconnection with a lever which operates the tableraising mechanism, or it can be oscillated by a reciprocating rack engaging a pinion when the machine with which the feeder is associated operates at timed intervals. In each case the wheel 1 takes the separated sheet while moving in a counterclockwise direction, and passes it on to feed rollers 6, 7 before the sheet is relieved of the suction action of the parts 8, which act in succession on different portions of the sheet as apertures 9 in the wheel move past a spring- pressed wood bushing 50 mounted in an arm 11 on a shaft 56, the bushing being saturated with oil and connected by a tube 33 to the main passage 28 of an air control device connected to a motor-driven suction pump. The suction arms 14 are connected by tubes 35, 36 to auxiliary passages 29, 37 of the air control device, and a sliding-valve 27 is operated by a lever 17, Fig. 2, on the shaft 15 of the arms 14 to cut off the suction to the arms 14 at the desired time. The air pressure in the conduits 28, 29 is controlled by providing vent apertures 42, 43 fitted with spring-pressed discs 39 having apertures of different sizes which can be registered with the apertures 42, 43. When the wheel 1 rotates continuously the bushing 50 registers with a curved slot 12 in the wheel to connect the pipe 33 to atmosphere to destroy the vacuum when the sheet has been taken by the rollers 6, 7. When the wheel 1 oscillates, the vacuum is destroyed by opening a relief valve 60, Fig. 2, by a pin 65 on the shaft 2 and a slotted link 66. Another hand-operated relief valve 69 is provided for breaking the vacuum at any time it is desired to stop the feed.
