Title: Treatment of case-hardened steels
Inventor: HAYNES ALAN GEORGE
IPC: C23C8/80
Filed: 1963-10-17
Abstract: A case-hardened steel part is quenched to a temperature at which the transformation of the core to martensite is substantially complete but at which the case is still austenitic, reheated to temper the core martensite, and then cooled to transform the case to martensite. The process is particularly applicable to gear parts.  Treatment of En 36, 39, 354 and 355 steels is particularly referred to.

Title: Synchronous digital systems
IPC: H04L7/033
Filed: 1975-09-19
Abstract: 1521029 Data transmission POST OFFICE 19 Sept 1975 [20 Sept 1974] 41131/74 Heading H4P A clock system for syncronous digital signalling apparatus, e.g. a data modem, comprises an oscillator 1 connected to a clock pulse output terminal 6; an input terminal 7 for the baseband signal with which the clock is to be synchronized; means to sample a signal applied to the terminal 7, including a zero-crossing detector 9 and a counter 16 arranged to respond to a predetermined number of zero-crossings detected by the detector; a tuned circuit 10 associated with zero-crossing detectors 8, 13 and arranged to oscillate in phase with the average phase of the sampled signal; and logic circuitry 14 associated with the counter 16, the tuned circuit 10 and a start/stop gate A, the arrangement being such that clock pulses are prevented from appearing at the terminal 6 during the sampling period, but appear at the terminal in phase with the oscillations in the tuned circuit 10 at the end of the sampled signal. The system may be used to achieve initial synchronization after transmission-reception change-over in simplex or half duplex operation, employing a 15 bit pseudo random binary sequence for the signal to be sampled. The long term synchronization is effected by comparing the timing of the clock pulses with the timing of the synchronous digital signal by means of an early/late gate 17, the result of the comparison being used to control, by way of a counter 18, a circuit 3 which adds or suppresses pulses from the oscillator I, thereby ensuring the provision of synchronized clock pulses at the terminal 6.

Abstract: 1313566 Photocomposing apparatus LINOTYPE GmbH 27 Aug 1970 [28 Aug 1969] 41270/70 Heading H4F In a photocomposing apparatus in which selected characters on a plate 12 are scanned by a cathode-ray tube 15 and reproduced on a display tube 19 which exposes a film 22, and in which the scale of reproduction of the characters (type size) is adjustable by devices 25a, 25b and 25c which adjust the amplitude of the writing beam of tube 19, these devices being coupled to correcting power supplies 26a, 26b, and 26c which control the starting point of the writing beam to ensure the composition of different type sizes on a single base line, additional correcting power supplies 33-38 are provided for composing exponents and indices (x and y in Fig. 2) and exponents of exponents and indices (i and k) and indices of exponents and indices (j and l) having the correct size and base lines 41- 46 (40 comprises the normal base line). The control unit 1 for the apparatus comprises a punched tape reader 4 and a control panel 3. Signals from the punched tape pass through a delay network 5 and a shift register 6 to a character width store 7 and a character storage means 10 which through a co-ordinate selector 11 adjusts the position of character plate 12 and through an amplifier 14 adjusts the position of scanned raster on CRT 15. Signals from the punched tape also influence a type size storage means 8 and a character location decoder 9. Amplifier 14 is also connected to X and Y deflection adjusting devices 16 and 17, device 16 defines the number of vertical scan lines per character and device 17 receives timing pulses for the Y-deflection produced by an objective 21, which is moved forward one step after each line scan of tube 19, a grid 23 being moved therewith between a light source and a photo-cell 24. Each character is raster scanned by a plurality of horizontally spaced (X-direction) vertical (Y-direction) scan lines. In normal operation the amplitude of the writing beam i.e. the type size of tube 19, is adjusted through devices 25a, 25b, 25c controlled by storage means 8, and depending on the type size an associated correcting power supply 26a, 26b or 26c controls the Y-starting point. For formula composition including exponents, indices and their exponents and indices, character position decoder 9 actuates one of the bi-stable flip-flops 27 to 32 which in turn actuates the associated one of the additional correcting power supplies 33-38 to control the Y-starting point (i.e. the position of the respective base lines 41-46, Fig. 2) and in addition actuates the required amplitude adjusting device 25a, 25b, or 25c to obtain the desired character size in accordance to the following table: The flip-flops 27-32 are reset by a "new character" input pulse. In addition the outputs of the flip-flops are connected to adjusting device 16 for the X-deflection which determines the width of the character exposed. Six codings on the punched tape are required for the formula composition.

Abstract: 923,362. Controlled non-linear inductors. HIGH VOLTAGE ACCESSORIES Ltd. Dec. 5, 1961 [Dec. 6, 1960], No. 41899/60. Class 40 (9). In a D.C. transformer employing two saturated cores SC 1 , SC 2  (Fig. 6) fed with opposed A.C. voltages, the load resistance R L  is common to both circuits, and is connected with rectifiers D 3 , D 4  so that it carries only the larger of the currents flowing through rectifiers D 21 , D 22 , this current being proportional to the direct current I d  to be measured. The connections to the windings on cores SC 1 , SC 2  are reversible by a ganged switch to cope with reversal in the direction of the main current I d . In another embodiment (Fig. 8), the potentials across separate load resistors R L1 , R L2  are compared by rectifiers 5, 6 and the larger potential difference determines the base potential of an emitter-follower transistor and hence the current through resistor R L . The constant magnetizing current component flowing through R L  can be eliminated by an equal compensating current, which is adjusted to produce zero p.d. across R L  when the main current I L  is zero.

Abstract: 1438846 Automatic voltage control HOLLANDSE SIGNAALAPPARATEN BV 18 Sept 1973 [26 Sept 1972] 43866/73 Heading G3R A power supply circuit comprises a first D.C. source and a first voltage regulator supplying a regulated output voltage. A second D.C. source is connected to the input of the first regulator by way of a second regulator responsive to the difference between the input voltage to the first regulator and the regulated output voltage. As shown, a source 1 supplies D.C. with a ripple voltage through a regulating transistor 7 controlled by a feedback loop 8 to produce a desired output voltage. The source voltage is sensed by voltage divider 24, 25 and compared in a differential amplifier 20, 23 with a voltage V nef2  derived from the regulated output voltage Vu. If the sensed voltage falls below a critical level, transistors 26, 27 cause transistor 17 to conduct, thus connecting a second source 11 with the input of regulating transistor 7. The presence of ripple on the voltage outputs of sources 1, 11 increases the efficiency of the supply.
