Title: Hydraulic machine tool with driven tool spindle
IPC: B23Q5/26
Filed: 1950-09-13
Abstract: 689,118. Drilling. DALES, H. Sept. 12, 1951 [Sept. 13, 1950], No. 22494/50. Class 83 (iii). A machine-tool comprises an axially-movable driven tool spindle 19 which, in an automatic cycle, is advanced to the work by a hydraulic piston 52, is then fed at a reduced rate, and, after a delay, is returned to its initial position. An electric motor rotates the spindle 19, carrying a drill, and also gearing 30 to drive a fluidpressure pump 31. The spindle 19 is journalled in a head 22 which, as it advances, engages manually adjustable stops 59, 67 secured to valves 58, 64. The pressure from the pump 31 is initially directed to passages 35, 41 ... 43 and through an adjustable valve 46 and a passage 63 to a chamber 39, whence it is directed to the pistons 52 to advance the drill-spindle against the pressure of springs 54. When the head 22 strikes the stop 59, the passage 63 is closed and the feed is then controlled by the setting of the valve 46. At the end of the feed movement, the head 22 moves the valve 64. The fluid then moves a piston 65, while the drill dwells at the bottom of its hole, allowing the fluid in the passage 41 to pass through passages 42, 82, 83 to the reservoir. The springs 54 then withdraw the drill, the fluid being expressed through a passage 70. The valve 65 is maintained in position by a spring- operated slotted cam-plate 76. To restart the cycle the cam-plate 76 is returned to its initial position by a handle 81. The unit may be mounted horizontally or vertically. Several units may be arranged to act in sequence.

Title: Improvements in or relating to a method of making an electric conductor adhering to an insulating support
Inventor: MILLER PHILIP JOHN FENNING
IPC: H05K3/18
Filed: 1956-07-21
Abstract: Nickel conductors are formed on an insulating support by deposition from a solution of the nickel cation-hypophosphite anion type.  In the formation of a wiring circuit, a panel of synthetic resin bonded paper or fibreglass is pierced where the components are to be connected to the conductors; roughened as by shot-blasting, covered at those places where the circuit is not required either by applying a photosensitive material all over, exposing the material to ultra-violet light through a negative of the circuit and then removing the unexposed material, or by printing with oil-bound paint or silk-screen ink; treated with stannous chloride solution and then with palladium chloride solution to deposit a thin film of palladium; immersed in a solution containing sodium hypophosphite together with either nickel chloride and sodium citrate or nickel acetate and sodium lactate, to deposit the nickel circuit pattern; and the material covering the remainder of the panel removed.  The nickel pattern may be thickened by re-immersion in the coating solution.  If desired, an initial coating of adhesive may be applied to the panel: roughening may not then be necessary.  According to the Provisional Specification, a copper circuit may be formed by depositing nickel on an insulating support, applying a negative pattern of the circuit to the nickel either photographically or by printing, electrodepositing copper on the exposed nickel, and removing the resist material and the nickel covered thereby.

Patent GB-937661-A (GB)
Title: Electronic tabulator
Inventor: HUNTLEY KEITH GORDON
Filed: 1958-07-16
Abstract: 937,661. Statistical apparatus. RANK PRECISION INDUSTRIES Ltd. Oct. 15, 1959 [July 16, 1958], No. 22829/58. Class 106 (1). Apparatus adapted to process data in accordance with given orders and to present a printed output comprises an input unit A, Fig. 1, e.g. a record card reader, a storage unit B, an arithmetic unit C, a device D for generating signals such that when they are applied to a cathode-ray tube E, corresponding legible characters are displayed on the screen, and a xerographic drum printer G for printing the characters displayed on to a moving web of paper. The operations performed by the arithmetic unit C are controlled by control signals from the record itself through the store B. The output from unit C and other data direct from the store B are applied to the character generator D. The control data in store B also passes to a unit F which contains a series of standard forms one of which is selected and projected on to the xerographic drum G together with the characters from the screen of the C.R.T.E. The printed paper may be cut to the required size and delivered by apparatus H. In the form of Fig. 2, the card reader 1 passes control data via a register 2 to a control unit 3 the output of which causes a unit 5 to generate order signals. These are applied with further data from the reader 1 to store 4. That part of the data that requires no processing passes directly to the character generator 12 to display the appropriate characters on the screen of the C.R.T. 13. Other data passes to the arithmetic unit 8 via an order decoder 6 controlled by the orders in store 4. The arithmetic unit 8 has input gates 7 and output gates 9 and the results are readout by unit 10 and passed to the generator 12. The order decoder 6 also selects any desired outputs from the function table store 11 which produces set combinations of signals for application to the generator 12 to cause the data to be printed at desired horizontal and vertical positions. The decoder 6 also selects the desired form heading for projection on to the xerographic drum with the data from the C.R.T. screen as above. The character generators D, Fig. 1, and 12, Fig. 2, may be as described in Specification 896,594. The location of the printing may be controlled as described in Specification 926,731, and the C.R.T. display may be controlled so that the printing is not affected by the speed of the paper web as described in the same Specification.

Abstract: 399,004. Valve modulating and amplifying circuits; multiplex wireless signalling. WALTON, G. W., 2, Dean Street, Soho, London. Aug. 15, 1932, No. 22883. Addition to 375,831. [Class 40 (v).] Local oscillations are applied to two coupled ,non- oscillatory circuits in such manner as to produce a balance as in the parent Specification, the principle being utilized for modulation by arranging the signal input to disturb the balance, thus releasing energy at the local frequency modulated by the signal. Local oscillations are applied at 7, Fig. 1, across impedance 6 to the anode and grid circuits of the valve 1, so that with no signal from the microphone 13, there is no oscillation on the output coil 4. The grid and anode circuits are aperiodic and are highly damped, e.g. by resistance. Feed-back from the coils 3, 12 only occurs when the microphone is operative and results in further amplification of the signal-modulated oscillation. The anode and grid polarizing batteries may be dispensed with by using a pair of symmetrically connected valves 1, 1a, as shown in Fig. 2. Valves arranged as in Fig. 1 may be cascade-connected, Fig. 3 (not shown). A system of low-frequency amplification such as a public address system &c. is shown in Figs. 4 and 5, the latter Figure showing a method of modulating the local oscillations at 56 by a microphone or pick-up 49, the modulated output from 13 being applied to the input of valve 1 in Fig. 4 ; or the modulation may take place in the grid circuit of valve 1 in Fig. 4. Fig. 6 shows a system of multiplex transmission in which the local oscillator E produces oscillations at two frequencies determined by circuits A, B, the oscillations being respectively modulated by microphones C, D in the grid circuit of a modulator F, the same principle applying as in Fig. 1.
