Abstract: 948,883. Electric selective signalling systems. HEALD MACHINE CO. April 17, 1962 [ April 17, 1961], No. 14825/62. Drawings to Specification. Heading G4H. In an apparatus for positioning a workpiece such that a number of holes may be drilled in it on a pitch circle, each hole is drilled separately and any error in the position of one hole is not accumulated with any error in a subsequent hole position. The machine operator is provided with a chart which indicates the quotient Q and remainder R of 2<SP>16</SP>/(the number of holes to be drilled). The figure 2<SP>16</SP> is the number of pulses produced by a transducer, coupled to the workpiece drive, during one revolution of the workpiece. The values Q and R are set on dials which are ganged to switches giving signals in binary octal scale. When the apparatus is started the workpiece is moved through the desired angle and a hole is drilled. Initially the error in the position of the previously drilled hole is stored in an error register. When the apparatus is started the signals Q are fed to set a main counter and the error is added to, or subtracted from, this in dependence upon its sign. In this way, any error in positioning the workpiece for the second hole is not added to that originating in the first positioning. Signals R are fed to a remainder counter. The main counter output is used to drive a servo motor, having conventional tacho-generator feed-back, which drives the workpiece through gearing. A known arrangement, comprising a movable and a fixed grid associated with four photo-cells, is coupled to the workpiece through gearing and provides pulses which indicate the amount and direction of movement. These pulses are fed to the main counter to count it down to zero whereupon a brake is applied. Any mispositioning of the workpiece when it comes to rest is an error value, which is stored for off-setting the next value fed to the main counter. The remainder counter and a remainder register operate as in conventional counting technique.

Abstract: 871,195. Cathode-ray tubes. DICK CO., A. B. May 13, 1958 [May 13, 1957], No. 15345/58. Class 39(1). In an electrostatic printing tube of the kind comprising electron-beam generating means and a target formed by an array of wires insulated from one -another, a portion of each wire being within the tube envelope whilst one end of each wire extends to the exterior of the envelope, these ends forming an array of spaced wire points, each adjacent pair of wire in the target array is interspersed by a shield electrode, the shield electrodes being adapted, when connected to a suitable source of potential, electrostatically to shield the wires from one another. As shown, alternate ones of wires 32, Fig. 1, constitute the shield electrodes and are connected by means of lead 38 to a suitable potential whereby discharges take place to the external anode 36 in preference to an adjacent shielding wire. Thus each wire may be altered electrically by the electron beam without an appreciable effect on its neighbours. Each wire may be clamped between glass rods 40, 42, 46, 48, Fig. 3, with one end 33 extending to the flat printing surface 44. Alternate wires 38 are connected to lead 38 by means of printed-circuit conductors 52 on insulating member 50. The glass rods are mounted in a slot in metal plate 30. An alternative form of target may be made by winding a shield wire 64, Fig. 5, around glass rod 60 and conducting strip 62, winding writing wire 68 around rod 60, strip 62 and glass strip 66 so that its turns fall between the turns of the shield wire and grinding away the wires at two sides. This assembly is sealed to a glass rod 70 and mounted in the metal faceplate 30. Since the shield wires 64 are bent away from the writing tips 68 the chances of discharge to the shield wire instead of through the dielectric medium 34 to the external anode 36 are reduced. Specification 871,194 is referred to.
