Title: Improvements relating to punching, drilling, reamering and like machines
IPC: B21D28/26
Filed: 1930-08-15
Abstract: 361,288. Punching and drilling machines. SEDGWICK, C. H. and SEDGWICK, E. B., 36, West Ferry Road, Millwall, London. Aug. 15, 1930, No. 24507. [Classes 83 (iii) and 83 (iv).] Spacing racks and like bars.-A tool head 4 carrying a punch 13 and die 14, or a drill, slides on fixed guides 2, 3 and is traversed step-by-step through the agency of a rack 20 reciprocated by the joint action of a face cam 24 and a continuously driven pinion 19. The gearing in the head 4 is driven from a pinion 5, Fig. 2, sliding with the head on a shaped shaft 6 constantly driven from forward and reverse driving pulleys 7, 8. This gearing comprises the pinion 19, Fig. 5, meshing with the rack 20, so that as the latter moves to the left in Fig. 1, the head 4 remains stationary owing to friction and as the rack moves to the right the head 4 is advanced thus providing a movement in steps with definite dwells for the punching &c. operations. The extent of each step depends on the ratio of a gear pair 16, 17 which may be changed or replaced by variable gearing. The cam 24, which is constantly driven from shaft 6 through a pair 26, 25, Fig. 2, actuates the rack 20 through a sector lever 21, Fig. 1. The work is supported with its edge on aT-bar 30, Fig. 5, and held by clamps 31, Fig. 1, or it may be adjustable by grippers movable by screws. To throw the punch out of action as required to leave gaps in a row of holes, a templet 36, Fig. 5, may be provided. This lifts a lever 33 on the tool head 4 which withdraws a packing-piece 32, or breaks a toggle, and so prevents the punch making a hole. The templet 36 may consist of a plank on edge with a series of holes 36<1>, Fig. 2, into which mushroom-head studs 35 are set wherever a hole is not to be punched. A pusher 42 coacts with tappets 43, 44 to rock a shaft 41 and so operate reversing belt-shifter 47.

Title: Suspension device for vehicles
IPC: B66C23/78
Filed: 1945-09-27
Abstract: 604,607. Vehicle spring - suspensions. ALLARD, P. J. M. T. Sept. 27, 1945, No. 25103. Convention date, Sept. 30, 1944. [Class 108 (ii)] [Also in Group XXX] In a suspension device for the driving wheels of vehicles such as mobile cranes, each wheel is supported by a lever connected to the vehicle frame by two resilient suspension members of different flexibility arranged in series, one operative under no-load conditions during road travel and the other, more rigid, becoming operative only after the first member has been fully deflected. The vehicle frame 1 is of T- shape, the limbs of which are of tubular section, the rear wheels being mounted in pairs on axles 18 which are each carried at the end of an arm 9 pivoted to the frame at 10 and connected by the springs 11, 12. Each pair of wheels comprises an outer driven wheel 7 and an inner carrier-wheel (not shown). The spring 11 may comprise helical compression springs in series, while the more rigid spring 12 may comprise an oleopneumatic device, a rubber block or a pile of spring washers, e.g. Belleville, washers. Each axle 18 is capable of oscillating about its point of connection with the arm 9, the outer wheel 7 of the pair being spaced nearer to the arm 9 than the inner carrier-wheel to obtain increased adhesion. To give increased stability and to take the load from the driving wheels 7 when the crane is in operation, detachable wheels may be positioned at the outer end of each axle 18. These wheels may alternatively be retractable, being carried by an arm pivoted about an inclined axis and swinging upwards to a position within the track of the outer running wheels when not in use. The front steering wheels 3, 4 are carried by a member 5 pivotally mounted about an axle 6 on the frame and may be arranged as described in Specification 19669/45, as open to inspection under Sect. 91.

Filed: 1938-08-26
Abstract: 518,434. Television receiver valve circuits. THORNTON, A. A. (Philco Radio & Television Corporation). Aug. 26, 1938, No. 25121. [Classes 40 (iii) and 40 (v)] In order to suppress noise or spurious transients in television reception, the receiver comprises in combination a wide-band signal receiver for example a superheterodyne receiver 1, a signal detector for example a diode-pentode VI, an amplitude limiting device for example valve V3 in a synchronizing channel, and a narrow-band transfer means for example filter 11, 12, 13, 14, 15 in the same synchronizing channel. In the system shown, the output of valve V1 is of the shape indicated at (a) and is fed through an amplifier 2 to a cathoderay picture reproducing device 3. The output of valve VI is also fed to valve V2 which is biased to give the output indicated at (b). This is fed to the amplitude limiting valve V3 which reduces the spurious signal 21 to the level of the synchronizing pulses 24 as indicated by 22 at (c). This output is fed to the low-pass narrow-band filter 11 ... 15 by which the spurious signal consisting mainly of high frequencies is still further reduced as indicated by 23 at (d), the filter altering the synchronizing pulse from the shape 24 to the shape 26 but reducing its amplitude only slightly. The output of the filter is fed through valve V4 to the line synchronizing generator 19 which controls the coil 5 of the picture-reproducing device 3. The output of the filter 11 ... 15 is also connected through a low-pass filter 17, 18 and a valve V5 to the frame synchronizing generator 20 which controls the coil 4 of the picture reproducing device. Alternatively, separate channels may be provided from the valve V1 to the separate synchronizing generators.

Title: Improvements in or relating to receivers for multichannel electric pulse communication systems
IPC: H04J3/04
Filed: 1946-08-23
Abstract: 624,514. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES, Ltd. Aug. 23, 1946, No. 25227. Convention date, Sept. 1, 1945. [Class 40 (v)] In a demodulator for multiplexed pulse time modulated signals, the various channels are distributed to a number of interlaced cathode-ray demodulator tubes by means of synchronizing pulses and phaseshifters. In any tube, adjacent electrodes handle non-adjacent channels. Twelve channel signals received at 16 are passed via shaper 37 to the control grid 33 of the demodulator tube 13 and similarly to the grids of tubes 14 and 15. These signals are also passed to a synchronizing pulse selector 17 which selects the pulses of channel one, which are wider than those of other channels, and serve as synchronizing pulses to produce at 18 a base wave having a frequency equal to the repetition rate of the pulses. Said base wave is applied through a phase splitter 19 to the tube 13 and, through phase-shifters and similar phase splitters to tubes 14 and 15 to provide the rotating sweep for the electron beams. Of the signals applied to the grid of tube 13, those of channels 1, 4, 7 and 10 will be demodulated during each full sweep of the beam, since the remaining channel pulses occur whilst the beam is between electrodes. The other tubes being displaced in phase, demodulate the appropriate remaining channels. Each collector electrode produces pulses having an amplitude proportional to the time during which the beam coincides with a collector electrode, and since the beam is swept at a constant speed, this time is proportional to the modulation time displacement of the signal pulses which are keying the beam. In each tube, signal pulses of the desired channels are admitted by gating pulses that are derived from the base wave and are synchronized to coincide only with the four desired channels of the demodulator tube. These gating pulses are obtained by passing the base wave through phase-shifter 43, frequency multiplier 44, full-wave rectifier 45, to a shaper 46 that selects the peaked output of the rectifier. Undesired pulses may also be blocked by mixing the output pulses of a given tube and feeding them back inverted to the control grid.

Title: Detection means for improperly lubricated journals
IPC: B61L1/20
Filed: 1958-08-11
Abstract: 837,527. Testing bearings. GENERAL RAILWAY SIGNAL CO. Aug. 11, 1958 [Sept. 30, 1957], No. 25690/58. Class 12 (1). [Also in Groups XXX and XL (c)] An improperly lubricated axle bearing on a railway vehicle emitting high-frequency sound signals is detected in passage by a directional electro-acoustic transducer positioned adjacent the track, and the position of its associated wheel relative to the other wheels of the vehicle or train is recorded. High-frequency sound signals emitted by the axle bearing are received by the directional transducer (microphone) 23, Fig. 1, the resulting electrical signals are amplified and passed through the band-pass filter 25 to remove signals outside the frequency range in which the bearing signals fall. The filter output is rectified to produce a D.C. pulse of a duration which is a function of the speed of movement of the wheel through the transducer beam ; this triggers the pulse former 27 to produce a pulse of fixed duration to energize relay DR. The associated contact 29 operates and a signal is recorded on one track of the dual track tape recorder 30; additionally the alarm bell 31 is operated. During the passage of each wheel, switch arm 13 is deflected thereby closing contacts 14 and 15 and energizing relay WC. Via the associated contact 32 a signal is recorded on the other track of the tape recorder. By inspection of the record the location of an axle bearing which is improperly lubricated can be determined.
