Inventor: FOWLER FRED
IPC: B21H3/10
Filed: 1960-11-16
Abstract: 925,096. Rolling; making fluted cutting-tools. FRED FOWLER Ltd. Feb. 16, 1962 [Nov. 16, 1960], No. 39275/60. Classes 83 (2) and 83 (4). A method of forming a fluted cutting-tool includes heating a wire blank to a forging temperature and rolling the wire between a plurality of freely-rotating rolls, movement of the blank past the rolls forming swarf clearance flutes in the blank. Wire blanks 12 are fed by an hydraulic pusher 15 from a magazine 11, past an induction heating coil 18, and through a cylindrical guide 20 to work rolls 24 and 25. The rolls 25 support the blank while the rolls 24 which include projections 39 and a knurled periphery form straight flutes. The rolls are radially adjustable and the rolls 24 can be skewed to give spiral flutes. The rolls 24 are synchronized by a Bowden cable 42, and for resetting the rolls are moved clear of the work and rotated in the reverse direction. A gripping head 41 is used for gripping small workpieces. Fig. 4 shows how the rolls 25 may be profiled to produce a land 36 and relief 37 on a blank, 35 being the swarf clearance flutes.

Title: Improvements in and relating to automatic control systems of the feedback type for variable speed electric motors
Filed: 1956-12-28
Abstract: 835,046. Automatic speed control systems. GENERAL ELECTRIC CO. Dec. 28, 1956 [Dec. 28, 1955], No. 39482/56. Class 38 (4). In a feed-back system for an electric motor wherein correction is effected by a servomotor energized from a source of substantially constant voltage and means are provided for cyclically closing and opening the servomotor energizing circuit to cause it to operate at average speeds dependent on the total duration of the energizing intervals per representative unit of time, the total duration of the energizing intervals per unit of time is made to decrease as the speed error decreases. The speed of Schrage motor 12, Fig. 1, is controlled by a reversible motor 18 which drives the brush gear 14 through a reduction gearing 17 in response to the actuation of a relay 52, or 54 by the current flow in circuit 31, 32, arising from the difference in voltage between the wiper 27 on potentiometer 25 and tachometer generator 24. The relays are energized by a pair of self-saturating magnetic amplifiers 34, 35, the control windings of which are arranged to cause their outputs to increase and decrease respectively when the error current is flowing in the direction of arrow 50, and vice versa. The amplifiers are described with reference to Fig. 2 (not shown). A circuit 60 which includes a condenser 62 which is shortcircuited through contacts on each of the relays when they are unoperated provides for inter-. mittent actuation of either of the relays whilst effecting a correction; the time of energization in an off-cycle decreasing as the error decreases to prevent overshoot.

Title: System for the transmission of signals and transmitters and receivers for use in said system
IPC: H04B1/68
Filed: 1967-08-30
Abstract: 1,137,457. Compandor system. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 30 Aug., 1967 [2 Sept., 1966], No. 39593/67. Heading H4R. In a compandor system the degree of signal compression at the transmitter is signalled as frequency modulation of a pilot signal which is used at the receiver to restore the original signal level. Transmitter, Fig. 1.-Audio signals from source 1 are applied via filter 2, amplifier 3 and single sideband modulator 4, 5, and 6, to a branching device 12 one path from which leads via a variable attenuator 9 to an output amplifier 7, while the other branch feeds an attenuator control circuit wherein the signal is mixed with a pilot tone from generator 31 and fed via amplifier 13 to a mean value rectifier 10 the output from which, after low-pass filtering in 11 is fed to a feedback control system controlling the setting of attenuator 9. In this control system a difference circuit 29 compares the output from filter 11 with the output from a frequency demodulator 30 and adjusts the frequency of oscillator 31 to tend to eliminate this difference, thus ensuring that the control signal to the attenuator 9 and the frequency of the pilot generator 31 accurately follow the control signal from filter 11. The pilot tone is also added to the signal in branching device 17 to be fed to the line 46 via the variable attenuator 9. Receiver, Fig. 2.-At the receiver the signal and pilot tone are separated by filters 34 and 22 and the pilot is fed, via level adjusting device 36, to mix with the signal at the input to the variable attenuator 21, and also to control the variable attenuator via an equalizer 43, limiter 40 and discriminator 39. The output from the discriminator is applied to a differencing circuit together with a signal derived by amplifying, mean valve rectifying, and lowpass filtering, the amplitude of the output from the variable attenuator so that the output from the differencing circuit controls the attenuator to restore the original signal level at the input to the demodulating system 23, 24, 25 and 26. It is suggested that frequency modulation of the pilot may be replaced by delta modulation or pulse width modulation.

Title: Character display
IPC: G09G5/30
Filed: 1975-09-25
Abstract: 1515309 Alpha-numeric character generation MULLARD Ltd 25 Sept 1975 [16 Sept 1974] 40244/74 Heading H4T In a system in which coded digital pulse groups represent alpha-numeric characters which on receipt are generated and displayed, special groups serve both as inter-word space markers and as control groups to initiate or cancel some form of enhancement of the display of succeeding characters. In a teletext system single lines of pages of text are transmitted during the frame flyback interval of a television signal, each line carrying a line identifying circle and the signals of each page a page identifying code. Each character is coded by 7 bits, but some sets of the 128 possible are reserved to indicate, combined with SPACE, such enhancements as "Display in a window in the TV picture (W)", "Flash on and off at, e.g. once per sec. (F)", and/or "Display in colour". In the TV set a normal picture may be displayed by closing switch 2, or a page may be selected for display by a 22 bit signal from unit 7. The successive lines from the selected page are stored in memory 8 and are led in turn to character generator 10, where a read-only memory constructs 5Î7 dot displays of the required characters, and unit 11 arranges the appropriate set of 5 dots for each in turn of the seven raster lines making one line of type, brightening the marked dots. If a colour CRT is available the characters will be in white until unit 14 recognizes the special interword "SPACE" code for colour, continued until a code word for "cancel colour" is encountered. Similarly code words for "Flash" (F) and "Cancel Flash" allow specified words to be intermittently brightened by a multivibrator 19 feeding an AND gate 20, e.g. at 1 Hz. If switch 2 is closed and a "window" code is received, switches 17, 22 are also closed, allowing blanking pulses to cause unit 3 to produce a dark window over part of the TV picture with the selected words alone displayed in the window. The units 6, 7, 8 are controlled by clock pulses 12 synchronized with the time base locked to the transmitted signals. The special control and SPACE codes take no more transmission time than the standard SPACE code. To avoid false switching two code words in succession are necessary to activate the "window", and a single code, ignoring the second of two in succession, to cancel "window". Other codes may be used to display special symbols, segments of diagrams or even special pages inserted between sections of transmitted text.
