Title: Improvements in master clip arrangements for rotary hectographic or like printing machines
IPC: B41L11/00
Filed: 1949-12-22
Abstract: 712,973. Copying documents; printing-surfaces. BLOCK & ANDERSON, Ltd. (Bonsch, F, R.). Dec. 22, 1949, No. 32883/49. Class 100 (2) In a rotary hectographic or like printing machine reverse rotation of the printing drum on which the master sheet is secured causes the clip securing the master sheet to be opened to release the master sheet. The clip member 9 comprises a bar radially slidable in a longitudinal groove 10 in the drum 1, and urged inwardly by springs. At either end the member 9 has a stud 20 extending through an aperture in an end plate 12 secured to the drum, the plates 12 preventing endwise movement of the member 9, and the apertures allowing sufficient radial movement to open and close the clip. Pivoted to one of the plates 12 at 23 is a plate 22 abutting one of the studs 20. A lever 26 is pivoted at 25 to the side frame and is spring-urged against a fixed stop 28. In the normal operation of the machine, a pin 24 on the plate 22 engages an abutment 29 on the lever 26 and causes the lever to yield against its spring, the clip remaining closed. If the drum is rotated in the reverse direction, clockwise, the stop 28 prevents the lever from yielding, and the pin 24 is displaced to rock the plate 22 and open the clip. In the open position of the clip, the pin 24 rests in a recess 30 in the abutment 29 to allow the clip to be releasably held open until the drum is again rotated in the normal direction. Specification 712,972 is referred to.

Abstract: 600,892. Assembling teat cups. ALFA-LAVAL CO., Ltd., and CLARK, T. L. Dec. 5, 1945, No. 32892. [Class 84] In a device for use in assembling teat cups, a tool for trimming a liner to length, a tool for inserting the metal ring in a liner and a tool for stretching a liner that has been inserted in its casing are mounted upon a common support and operated simultaneously by the movement of a foot - lever. As shown, the stationary parts of the tools are supported by arms 2 on a tubular standard 1 and the movable parts are connected by arms 4 to a slidable rod 3 within the standard operated by a foot-lever 6 against a return spring 5. The trimming tool comprises a rotatable knife holder 11, carrying a length gauge 12, and a roller 9, attached to a bracket 4a connected to one of the arms 4. The knife holder is connected by a helical spring 14 to a collar 15 which is rotated to press the knife against a liner on the roller 9 and locked in position by a grub-screw, the depth of cut being limited by a roller adjacent the knife. The roller 9 is rotated by an attached pinion 10 engaging a fixed rack 8 when the lever 6 is operated. The tool for inserting the ring is generally similar to that described in Specification 302,929, [Class 84]. A sliding collar 19 carries pivoted arms 20 for expanding the end of the liner over the ring placed on the upper end 18 of a fixed support 17. The arms 20 are provided with studs 20a for limiting the depth of insertion of the ring and are returned to normal position by an elastic ring 21. The stretching tool is similar in principle to that described in Specification 270,316, [Class 84]. A tube 24 carrying the expander 25 slides on a fixed rod 23 having a wedge-shaped upper end. The liner is retained by locking cams 28 on a gallery 27 on the upper end of a slidable cylinder 26. The cylinder and tube move down together until the latter is stopped and the former continues to move against a spring 29 to effect the stretching of the liner. On the return stroke, a stud 26a lifts the expander off the wedge end of the rod 23, allowing it to contract and release the liner. A tool 32 for folding back the end of the stretched liner over the end of the teat cup, similar to that described with reference to Fig. 3 of Specification 287,572, [Class 84], is suspended above the stretching tool by the extended central bar 30, to which the expanding arms 31 are hinged.

Abstract: 741,787. Rectifying. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 27, 1953 [Dec. 1, 1952], No. 32999/53. Class 38 (2). A circuit arrangement for producing a variable high direct voltage from an oscillator is characterized in that the anode supply voltage of a tube in the oscillator is varied in a stepwise manner. The anode circuit of an oscillator tube 1 includes the primary winding 2 of a transformer; the supply voltage for this anode circuit being a stepped voltage which is produced across a condenser 18 by a cathode follower circuit comprising a tube 15 and a condenser 16, the tube being driven by a generator 19 which develops a stepped voltage. Thus the amplitude of the alternating voltage developed by the oscillator at a frequency of 100 kc/s. also varies stepwise causing the high direct voltage produced by a rectifier 6 to vary likewise. Since, at this frequency, the stray capacities in the rectifying circuit form sufficient smoothing the rectified high direct voltage varies sufficiently rapidly. Examples given are 6, 8 and 10 kv. each maintained for <SP>1</SP>/ 100  second.
