Title: Improvements relating to programme control of machine tools
Inventor: STOKES JOHN ARTHUR
IPC: G05B19/16
Filed: 1955-07-05
Abstract: 791,558. Programming for machine tools. BRITISH THOMSON-HOUSTON CO., Ltd. July 5, 1956 [July 5, 1955], No. 19421/55. Class 83 (3). [Also in Group XXXVIII] A machine-tool, in which a part is controlled according to a magnetic-signal-programme related to the instantaneous position of the part, comprises a body 2, such as a tape, disc or drum, having a track 6 representing the programme, a co-operating reproducing-head 4, and means 1, 3 for moving the body and head relatively to one another as the part moves. The motor 1 moves the table of a planing machine at a speed determined by the track 6. The track is the demarcation-line between regions 7, 8 of opposite magnetic-polarity. The reproducing- head has two helical-slots 10 displaced by 180 degrees and containing a wire 11 which traverses the slots in a figure-of-eight and is connected to a phase-conscious rectifier-circuit 13. The head is rotated at a high-speed and the slots 10 scan the width of the record to produce a cyclicallyvarying induced-output-voltage, the instantaneous phase of which depends on the displacement of the track 6 from the edge of the drum at the point instantaneously lying opposite the head. The rectifier thus produces a unidirectional voltage proportional to the recorded speed, the voltage being passed to a voltage-responsive speed-control circuit 14. The direction of movement, instead of the speed, of the part may be controlled. Specification 761,918, [Group XXXVIII], is referred to.

Title: Improvements in Intensity Control for Vector Generators.
IPC: G01S1/02
Filed: 1967-04-28
Abstract: 1,178,455. Cathode-ray tube circuits. SANDERS ASSOCIATES Inc. 28 April, 1967 [28 April, 1966], No. 19695/67. Heading H4T. In a cathode-ray tube display system in which individual vectors are traced in uniform time intervals regardless of their length, constant brightness of all traces is achieved by controlling the tube beam intensity during the tracing of a particular vector by a voltage proportional to the length of such vector and derived from the sum of two voltages proportional, respectively, to the X and Y components of the vector. Referring to Figs. 1 and 2, voltages proportional to the #X, #Y coordinates of a vector AB are derived from respective generators 13, 17 and utilized in modulators 12 and 16 to amplitude modulate the zero and quadrature phases of an A.C. signal from a generator 10. The modulated signals are then added in a summing network 18 and supplied via filter 20, which passes the modulated fundamental frequency only, to a peak detector 22 the output of which constitutes the required beam intensity control voltage for the display tube 9. Although the peak detector 22, inherently, has a fast rise time its decay time may be too slow to allow a sequence of vectors to be drawn at speed and to overcome this a discharge signal is applied via connection 22a at the end of the vector tracing periods. The A.C. signal produced by generator 10 may have a sinusoidal waveform but by utilizing a square waveform the fundamental sine component of which is passed by the filter 20 the modulators 12 and 16 (Fig. 3, not shown) may be constituted by simple diode circuits instead of the more complex circuits which the modulation of sinusoidal waves require. An arrangement for generating two square wave trains in phase quadrature utilizing two flip-flops and four AND gates, the whole being controlled by clock pulses is described with reference to Fig. 4 (not shown). Although described in connection with a cathode-ray tube display the invention is stated to be useful for the intensity control of other types of display devices such as an X-Y recorder.

Title: Improvements in or relating to anti wheel-spin devices
IPC: B60L3/10
Filed: 1969-04-17
Abstract: 1,246,053. Fluid-pressure brakes. MASCHINENFABRIK OERLIKON. 17 April, 1969 [17 April, 1968], No. 19726/69. Heading F2F. [Also in Divisions G3 and H2] An electrical device for limiting wheel slip in rail locomotives comprises means for producing a vehicle speed signal, means for producing a driving wheel speed signal, means for comparing the two signals to produce a wheel slip signal and slip control means to which are supplied both the slip signal and the vehicle speed signal. The vehicle speed is measured by a separate wheel 6 carried by a spring loaded and damped arm (Fig. 2, not shown) and having a heater for icy conditions. The output voltages of tachogenerators driven by the wheels 1 and 6 are compared at 19 and any difference is supplied as a signal S to a unit 24 and according to its polarity this reduces either the magnitude or frequency of the motor supply or the effect of a pneumatic brake 22 which is actuated by a cylinder 21 controlled by a valve 23. Regenerative or rheostatic braking may also be controlled. The unit 24 incorporates a "dead band" circuit whereby no correction is made until the slip exceeds a point at which maximum adhesion occurs (point A, Fig. 1, not shown) and this point is adjusted according to the vehicle speed signal VT and the motor count J, measured at 16, which is taken as a guide to the condition of the rail surface. An overriding limit is imposed beyond which the dead band is not extended. The dead band may also be controlled by the driver. The comparator 19 receives signals of motor count J and a brake pressure p, measured at 20 and when these, together with the vehicle speed, are of such values that it is evident that slip cannot occur any residual slip signal is switched to a servomotor which adjusts a potentiometer in circuit with the driving wheel tacho-generator so that the slip signal becomes truly zero. The driving motor 18 may be energized from an A.C. supply 13 by a transformer 15 and thyristor rectifiers 17 by which speed is controlled, and 17 may act as a converter for regenerative braking, controlled by the slip control signal. Alternatively rheostatic braking may be used the motor field being supplied by rectifiers controlled by the slip control signal. As other alternatives it is mentioned that the motors may be asynchronous A.C. machines controlled by frequency adjustment or the supply may be D.C with thyristors 17 acting as a "chopper". There may be several driving motors individually or group controlled. During normal running, control is by a signal S from the drivers controller 25. In Fig. 11 (not shown) the motor supply rectifier comprises a thyristor bridge controlled by the difference between the actual motor current J and a reference value Jc which is reduced by the slip controlled signal.

Vacuum tubes; R÷ntgenray tubes. - In producing high vacua in vacuum tubes such as rectifiers, transmitting valves, valves with oxide or other highlyemissive cathodes and Rontgen-ray tubes by vaporizing magnesium or other substance, this substance is carried upon a support from the anode or other element of the electrode system, the substance being vaporized only after the anode &c. has been incandescent for some time and has been freed from gas and the dimensions and material of the support determining approximately the whole period of time between the commencement of incandescence of the anode &c. and the vaporization of the substance. The magnesium or other substance 6 may be carried by a metal strip 9 welded to the centre of the anode 5 of a 3-electrode tube so as to be heated by conduction and radiation of heat from the anode. The substance 6 is mounted in such a position that the electrode system screens the foot 8 and a part of the bulb to prevent the formation of a metallic deposit thereon. A metallic bridge between the electrode leads is tbus avoided whilst the clean part of the bulb allows dissipation of heat from the filament without heating the cap of the tube. The anode 5 is made incandescent by electron bombardment or eddy currents and the substance 6 may be additionally heated by eddy currents in the latter case. The Specification as open to inspection under Sect. 91 (3) (a) comprises also arrangements in which the substance 6 is heated solely by radiation, the substance 6 being on a glass or metal carrier 7 on the bulb 1 or on the foot 8 or on the electrode system. This subject-matter does not appear in the Specification as accepted.
