Title: Improvements in or relating to control apparatus for machine tools
IPC: G05B19/04
Filed: 1954-03-09
Abstract: 787,176. Machine-tool details. LEBER, F. March 9, 1954 [March 11, 1953], No. 6875/54. Class 83 (3). Control-apparatus for machine-tools for effecting, e.g., speed-and-feed changes, comprises a selector-drum having conductive segments, each of which forms part of an electric-circuit coupled to initiate a particular operation, setting-rings rotatably mounted on the drum, and an operation-control-switch having a contact for each setting-ring. An operationselector-switch 2, which may be hand-operated or moved around at intervals by a part of the machine, directs current from a battery 18 to one of a number of rings 6 rotatable on a stationary drum 10. The latter is similar to a commutator and each ring, which is insulated from the others, carries a contact or brush which may be pre-set to a particular segment of the drum. Leads 11 connect the drum-segments to a relay-device which comprises switch-bars 16 pulled to the right by solenoids 17 against springs at the opposite ends. The rods have sets of contacts which complete circuit-combinations to operate through further solenoids 12, hydraulic valve members 13, 13a, &c., which in turn set piston-and-cylinder devices 20 operating to shift change-gears 5, 5a, &c., or other controls of the machine.
Patent GB-695317-A (GB)
Title: Phase discriminating arrangement
Inventor: COURT PATRICK RICHARD JAMES
IPC: H04N5/12
Filed: 1951-03-22
Abstract: 695,317. Automatic frequency control systems. PYE, Ltd. March 24, 1952 [March 22, 1951], No. 6930/51. Class 38 (iv). [Also in Groups XXXVI and XL (b)] The frequency of an oscillator (e.g. a television scanning oscillator) is controlled by a train of synchronizing pulses occurring at the mean frequency of the oscillator or at a multiple or sub-multiple thereof, by deriving from the oscillator two simultaneous series of pulses of opposite polarity and applying them to a phase discriminator to change the conductance thereof, so that the sync. pulses pass the discriminator and develop on its output side a control potential which varies according to the relative phases or overlap of the sync. pulses and the oscillator pulses. In Fig. 6, the sync. pulses are separated from the received picture signal in the valve VI, and are differentiated at the transformer T1 to produce the signals shown in dotted lines in Fig. 5 which are applied to the anode of one diode V2B and to the cathode of a second diode V2A. The other electrodes of the two diodes are connected to each other through resistors R14, R15, and through condensers C8, C9 to the opposite ends of a secondary coil of a transformer T2, which feeds the line scan coils. Pulses of opposite polarity, shown in full lines in Fig. 5, are thus applied to the diodes V2A, V2B to render both conductive during the short pulse periods 1 ... 4. When the scan oscillator is running in correct frequency and phase, the sync. pulses occupy the position shown in Fig. 5, with the rising exponential portion occurring during the periods 1 ... 4. Want of synchronism reduces or increases the area of overlap, and so affects the output voltage between the junction of resistors R14, R15 and earth. This voltage is smoothed and applied to the grid of an amplifier V4A, the output of which is applied to the grid of a blocking oscillator V4B to adjust its frequency in the corrective sense. The blocking oscillator develops at its anode a sawtooth voltage which is applied to the grid of the scanning amplifier V5. Frame synchronizing pulses, and interference pulses, occurring during the intervals between the line sync. pulses, are unable to pass the blocked diodes V2A, V2B and cannot affect the automatic control. Noise occurring on the leading or trailing edges of the sync. pulses cannot affect the control, as the diodes are blocked at these times. Noise occurring during the pulses may be removed by clipping, or by the method described in Specification 692,359. The use of positive bias applied to the grid resistor R10 of the separator valve V1 levels off the base of the pulses by grid current. In a modified form of the invention, Figs. 1 and 2 (not shown), the sync. pulses are not differentiated before their application to the diode valves V2A, V2B; and in a further form (Figs. 3 and 4, not shown), differentiation is effected by a resistance-capacity network.

Abstract: 101,673. Davey, H. May 15, 1916. Automatic gear.-A constant terminal pressure in the low-pressure cylinder of a compound condensing-engine is maintained by controlling the main exhaust valve-gear by the pressure in the condenser. In the construction shown in Fig. 1, a mercury column under the condenser pressure varies the time of release of the detent g and so the time of closing the exhaust valve a. In the construction shown in Fig. 2, a mercury column acts through an hydraulic relay 8 to control the position of the exhaust cam 7. In a modification of this construction, the hydraulic relay is dispensed with.

Title: Process for the electrical separation of rubber from rubber latex
IPC: C25D13/18
Filed: 1929-03-04
Abstract: 307,747. Siemens & Halske Akt.- Ges. March 12, 1928, [Convention date]. Latex, coagulating.-Materials such as rubber are deposited from a suspension or latex by application of a balanced alternating current. The frequency of the current may be up to 150. The electrodes are preferably of aluminium or tantalum or their alloys and are preferably covered with a porous non-conducting or semi-conducting material such as plaster of Paris or a metal oxide; with such coverings electrodes of iron or lead may be used. In depositing rubber from latex the electrodes may be separated from the latex space by porous walls, the electrode space being filled with water or a solution of a salt, acid or alkali, or with a dielectric liquid' such as oil, glycerine or alcohol. The liquid in the electrode space may be continually renewed during the operation. The working voltage may be 40-150 with uncovered electrodes, or 20-50 with covered electrodes. The quality of the deposit may be varied by the addition of materials such as dyes, sulphur or soot. The added materials should preferably be such as exhibit in suspension an electrical charge of the same sign as the latex particles. The latex may be used directly as exported or may be converted by the addition of compounds such as thorium nitrate.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B61H9/00
Filed: 1919-03-20
Abstract: 144,402. Cloud, J. W. March 20, 1919. Fluid-pressure.-In apparatus of the type in which the brakes on one or more selected vehicles of a train (e.g. the locomotive) can be applied independently of or simultaneously with those on the remaining vehicles, the triple valves on the selected vehicle or vehicles are unresponsive to reductions in train-pipe pressure less than a predetermined amount, such as that necessary for service applications of the brakes. In one arrangement, the locomotive triple valve 6 is connected to the train-pipe 11 at 11', to the brake cylinder 5 at 5<1>, and to the auxiliary reservoir 4 at 4<1>, and the brake cylinder exhaust port 21 is connected to the pipe 13. The main reservoir 3 is connected to a pipe 12. A spring 22 opposes the movement of the triple-valve piston 14 to application position. The trailer vehicles are provided with an ordinary triple valve 9 and equipment. To effect a simultaneous application of the brakes throughout the train, the trainpipe 11 is connected by the driver's valve 7 to the pipe 13 so that the triple valves 9 are actuated and the train-pipe air feeds into the locomotive brake cylinder 5 by the port 21 and cavity 18, Fig. 2. The train-pipe pressure reduction in this operation may not be sufficient to actuate the locomotive triple valve, but, in the event of the breakage of a coupling, the spring 22 is overcome and the auxiliary reservoir 4 is then connected to the brake cylinder 5. To apply the brakes only on the locomotive, the pipes 12 and 13 are connected to supply air from the main reservoir 3 to the brake cylinder 5 by way of the exhaust port 21. Simultaneous or separate release of the locomotive and trailer vehicle brakes may be effected by connecting the pipe 13 to atmosphere and the train-pipe 11 to the main reservoir pipe 12. In a modification, the auxiliary reservoir 4 on the locomotive is dispensed with, the main reservoir 3 being connected to both the pipe 12 and the triple valve. There is no feed passage between the train-pipe and reservoir chambers of the locomotive triple valve, the piston of this valve seating tightly when in the release position. The operation is substantially the same in this case.

Abstract: 1,162,615. Electric timepieces. CENTRE ELECTRONIQUE HORLOGER S.A. Feb.15, 1968 [March 13, 1967], No. 7390/68. Heading G3T. A mechanical resonator for a timepiece comprises two branches 1, 2 which oscillate in phase opposition, at least one of the branches being formed with a cavity 12 to receive a compensating device comprising a chamber 13 containing a mass 16, 18 which is free to move in the chamber and thus compensate at least partially for the variations of the frequency of the resonator due to changes of its orientation. The resonator is secured by screws 4 to a support and the branches have holes 10 to reduce their weight. Masses 5, 6 are secured to the ends of the branches and cooperate with a coil 7 to form an electromagnetic transducer for maintaining the oscillations of the resonator which is made of metal. A rotatable eccentric member 11 is provided for manual fine adjustment of the resonator frequency. Since the mass 16, 18 is free to move in the chamber 13, the compensating device automatically corrects the resonator frequency for changes in position of the resonator by allowing the centre of gravity of the mass to move according to the change in position. In one form the mass 16 comprises a ruby or sapphire ball having a bore 17 in which a plug 18 of gold is inserted, the ball being surrounded by a viscous fluid. Several modifications of the compensating device are described and the branches may each be provided with a compensating device and a member 11. Reference has been directed by the Comptroller to Specification 1, 060, 702.
