Inventor: WALDRAM JOHN MALYON
IPC: H02G3/00
Filed: 1955-03-10
Abstract: 788,864. Control system for consumption apparatus. GENERAL ELECTRIC CO., Ltd. March 8, 1956 [March 10, 1955], No. 7081/55. Class 38 (4). A circuit for controlling a load L comprising one or more electric lamps has the load L connected in series with contacts K of a relay between two supply conductors P, N, an operating coil W of the relay being connected between a control conductor C and the load terminal connected to the supply conductor N, this arrangement being provided with two pushbuttons A, B and a resistor S all connected in series between the supply conductors P, N, the junction between the two switches A, B being connected to the control conductor C. Closure of the push-button A completes a circuit from conductor P to conductor C, through the relay operating coil W to conductor N. Energization of the coil W thus closes contacts K and the load L is supplied from the conductors P, N. The relay is made self-maintaining by the provision of a resistor R. Closure of the pushbutton B shunts the relay coil W by the resistor S; the relay thereby falling out to extinguish the lamps L. The push-buttons A, B are interlocked to prevent their simultaneous operation. A number of such circuits may be interconnected as shown in Fig. 2, the control conductors being interconnected by removable links D12, D18, D24, D34. Thus the lamp loads can be controlled from one or a number of positions according to the arrangement of the links. If when all the links are in a pushbutton A is made in one circuit whilst a pushbutton B is made in another circuit, the resistors S function to limit the short-circuit current.

Title: Improvements in characters and character-bearing elements for use in the photographic composition of type matter
IPC: B41B15/12
Filed: 1950-03-22
Abstract: 687,722. Photographic type-composing. IN. TERTYPE, Ltd. March 22, 1950 [June 8, 1949], No. 7132/50. Classes 98 (i) and 98 (ii). A type-character-bearing element for use in the photographic reproduction of type matter, to produce a transparency for use in preparing a transparency for use in preparing a printing surface by the gravure process, comprises a photographable typographical character having an internal pattern of spaced lines terminating short of its outline so as to provide within the defining outline of the character, a facsimile of a line-screen in spaced relation to the outline, whereby to produce a plurality of ink-retaining depressions separated by non-printing ridges, surrounded by a marginal ink-retaining channel or gutter, when the character borne by the transparency is reproduced by etching in a gravure printing surface. The character may be reproduced by transmitted or reflected light. As shown in Figs. 3, 3b, and 3c, a photographic enlargement of a photogravure screen is made to provide an opaque negative print 30 (Fig. 3), the background ground area 36 is blacked out manually (Fig. ab), and the outline 40 is inserted manually in white (Fig. 3c). The enlargement is photographed to produce a positive, and a greatly reduced negative is prepared from this positive and a circular plaque for insertion in a matrix for use in the type-composing machine is cut therefrom. Where the final photographic composition is to be effected by reflected light, the character and background in the negative are opaque and in contrasting colours. The positive may be prepared directly without first forming a negative, and the screen pattern itself may be formed manually. A single-line screen may be used instead of the cross-line screen. The positive transparency of the type matter formed in the type-composing machine is printed on to carbon tissue, together with any pictorial matter, and the carbon tissue is used to prepare an intaglio printing cylinder. The characters need not be mounted in matrices adapted to circulate through the type-composing machine, but may be mounted upon a rotatable drum. Specifications 8046/05, [Class 98], 496,927, 568,929 and 615,559 are referred to.

Patent GB-765027-A (GB)
Title: High speed counter
Inventor: BLISS HARVEY NOBLE
IPC: G06M1/26
Filed: 1955-03-11
Abstract: 765,027. Counting-apparatus. VEEDERROOT, Inc. March 11, 1955, No. 7185/55. Class 106 (1). A counter comprises at least two number wheels interconnected by continuous gear type transfer mechanism including planet gears carried by a support for movement about the axis of the number wheels, means for effecting such movement to an extent limited by a cam which rotates with the lower order wheel so that numerals on the number wheels are correctly aligned for reading. The counter comprises number wheels 21-26, the first numeral wheel 21, Fig. 5, being fixed to a shaft 17 rotatable on a shaft 16 and being connected to the second wheel 23 by the reduction gearing transfer mechanism 34, 36, 37, 39. Geneva type transfer mechanism connects the other orders of the counter. The gears 36, 37 are carried by a shaft 48 supported between the limbs 29, 30 of a U-shaped frame 27 pivoted about the axis of the spindle 16. The pinions 40 of the Geneva-type transfer mechanisms are carried by a spindle 41 parallel to the spindles 16, 48. An arcuate arm 50, Fig. 3, free on the shaft 41, has a slot through which the shaft 48 extends. The arm 50 is connected to a pin 49 fixed to the spindle 41 by a spring 51 and carries a follower 56 which is normally held in the position shown in Fig. 3 by a spring 61 and which co-operates with a snail cam 43 fixed to the number wheel 21. A shutter 66 normally covers the number wheels 23-26, Fig. 1. When the counter stops and a reading is desired, the shaft 41 is rotated counter clockwise, Fig. 3, by a handle 65, Fig. 5, through an angle determined by a fixed stop. The pin 49 thereupon moves the shutter 66 to bring the wheels 21-26 into view. The arm 50 follows the movement of the shaft 41 under the action of the spring 51 until the follower 56 meets the surface of the cam 43. The frame 27 is thus moved and the number wheel 23 is rotated backwards by the planet gears 36, 37 by an amount corresponding to the reading of the wheel 21 to correctly align the wheel 23 with respect to the viewing window. Reverse rotation of the wheels 24-26 is effected by the transfer mechanisms if necessary. Should the shaft 41 be moved when the counter is operated the cam 43 can still rotate as the steep face 46 of the cam 43 moves the follower 56 against the pressure of a spring 61.
