IPC: B24B55/06
Filed: 1952-11-15
Abstract: 735,718. Confining dust generated by grinding wheels. LUKE & SPENCER, Ltd. Feb. 12, 1954 [Nov. 15, 1952], No. 28857/52. Class 8 (2). A vertical grinding wheel 14 partially shrouded by a suction guard 16 and having an adjustable work rest 10 located above and spaced from the point of entry 17 of the wheel into the guard has means, e.g. a sliding plate 15 connected to and controlled by the workrest 10 for controlling the entry of air through the aperture 17. The adjustable workrest 10 is supported by the machine frame 11 by an offset sliding bracket 12, and the plate 15 is held in sliding contact with grooves in the top edge of the guard 16 bounding the aperture 17 by springs 19 around bolts 18 on each side of the plate and of such length as to allow of limited vertical adjustment of the workrest relative to the plate; the plate 15 thus being able to follow the workrest in its horizontal movement relative to the wheel periphery and thereby maintain constant the aperture 17. Entry and exit of air where the wheel 14 leaves the guard 16 is controlled by a shutter 25 sliding in guides 26. In a modification the sliding plate controlling the aperture 17 is formed with a vertical box-like extension of the guard which telescopes with another boxlike member depending from and secured to the workrest.

Title: Improvements in or relating to modulated carrier wave receivers
IPC: H03D5/00
Filed: 1936-10-23
Abstract: 483,671. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 23, 1936, No. 28907. Convention date, Oct. 23, 1935. [Class 40 (v)] [Also in Group XXXV] Phase-modulated waves are demodulated by arranging a local oscillator or detector of a heterodyne receiver slightly out of phase, so that the local oscillation and the carrier are approximately 90 or 270 degrees apart, means being provided for automatically maintaining the desired relation between the signal and relatively-dephased local oscillator. The phase-modulated high frequency signal is fed to the control grids g of differential detectors 1 and 2 in push-pull, and a local oscillator 3 supplies oscillations by way of inductance 21 and phase shifter 10, co-phasially to their suppressor grids g<1>. The oscillator 3 is controlled from the input leads 4 by means of a potentiometer 8, phase-shifting line 9 and inductance 16 coupled to inductance 18, so that the voltage on electrodes g<1> is 90 or 270 degrees out of phase with the carrier. The amplitude variations produced by valves 1 and 2 are supplied to the amplifying-valves 13, 14 in push-pull and their outputs are combined in push-pull for the reception of phasemodulated waves. For the reception of amplitude-modulated waves, the outputs of 13 and 14 are connected in parallel. If the relative phase of the voltages on grids g and g<1> is upset an unbalance occurs in the detector plato circuit, a voltage appears across resistances 15, 17 and is passed through a time-control network 21 to the grid of the control valve 25. This varies the effective value of the inductance 20 and consequently the tuning of the oscillator an amount sufficient to correct for the deviation in phase ; the time-control circuit prevents the rapid variations of the signal from affecting the phase of the oscillator. In Fig. 2 (not shown), a complete superheterodyne system is shown with differential diode second detectors. Incorrect phase of the auxiliary oscillator coupled to the diode detectors is corrected in a manner similar to that described above, except that the control valve 25 operates to vary the tuning of the frequency-changing oscillator feeding the first detector.

Abstract: 485,856. Sliver - billing machines. FAIRBAIRN LAWSON COMBE BARBOUR, Ltd., and BEE, J. R. Oct. 24, 1936, No. 28922. [Class 120 (i)] A sliver - balling machine having measuring mechanism of the type in which means are employed for ejecting the finished ball or roll when a predetermined length of sliver has been wound and in which a defective roll may be ejected by hand, comprises devices controlled from the delivery rollers of the carding or like machine from which the sliver is supplied so as to cause the ejection of a completed roll and to wind-up a weighted chain upon a drum which when released by the measuring devices or by hand will re-set the measuring devices in their initial positions. The sliver is delivered to the balling mechanism through guides 2, 5 by rollers 3, 4 having associated change-gearing 6, 7, 8 driving a shaft 13 and worm-gearing 16 17, 19, 20 the worm-wheel 20 being fixed to a chain drum 20a and having a projection or pin 22 extending laterally therefrom and being mounted freelv on a stud 21 and driven anticlockwise. The projection 22 engages a pin 23 extending from a weighted lever 24 and thereby lifts a projection 4b on a lever 24c vertically, until, the pin 22 passing beyond its end, the projection 23 descends under gravity and the lever 24c returns to rest against a member 25. In rising, a lateral projection 26 on the lever 24c comes in contact with the rear surface of a plate or projection 27a on a lever 27 pivoted at 27b and lifts the top end of the lever 27 until it passes beyond the end of the projection 27a. In descending, the projection 26 strikes the front of the flange 27a and the lever 27 then moves clockwise and a pin 27c thereon engages a lever 27f so that its lower end 27d strikes against and raises a rod 28. A collar 28a thereon then raises the end of a lever 29 and carries a projection 29a thereon from between discs 30 which are then brought together by spring action, the plates 30 then commencing to revolve and a cam surface 30a forcing the runner 31 of the lever arm 32 to raise the worm 19 out of contact with the worm wheel 20. The weighted chain 33a then rotates the wormwheel 20 clockwise until arrested by the pawl 34. The lever 29 may be operated manually.

IPC: H04B7/06
Filed: 1926-11-17
Abstract: 261,758. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Usselman, G. L.). Nov. 18, 1925, [Convention date]. Directive signalling; fading, preventing.- In a directional system of wireless, fluctuation of signal strength due to fading is avoided by constantly varying the angle of the beam path. As shown in the Figure, a main " doublet " aerial 1 is backed by two reflector aerials 2, 3 arranged parallel to the first and a quarter wavelength away from it. Each reflector aerial is connected by leads 4, 5 to a variable condenser, the moving vanes 8, 9 of which are rotated bv a motor 10. As the vanes rotate the reflectors 2, 3 are alternately tuned to the fundamental frequency of the main aerial 1, so that first one and then the other determines the directional path of the radiating beam. The angular distance between the reflectors determines the extent of wobble, which may vary according to circumstances. The angular variation may be in the horizontal or vertical plane, and may occur at an audible or supersonic frequency.

Patent GB-997963-A (GB)
Title: Improved method and apparatus for the control of machine tools or the like
IPC: G05B19/14
Filed: 1961-08-16
Abstract: 997,963. Programmed control systems. AUTOMATION Inc. Aug. 16, 1961 [Aug. 16, 1960], No. 29631/61. Heading G3N. The invention relates to an automatic position/sequence control system for e.g. a turret lathe. A series of keys or punched cards (54) marked with the machining operation are set up in a key reader (34). The corresponding final tool/ workpiece position is set up on dials (36), and compared with the actual tool position as sensed by position transducers to control the "depth of cut". The individual keys are selectively coded to initiate a particular machine function or functions. These functions relate to such operating factors as the tools to be used, the operations to be performed, and the operating sequence to be followed. The control dials are manually settable to provide the desired position data which controls the location of the workpiece as each function is carried out. A first run may be made during which the dials are set for positioning the machine tools during subsequent repetitive runs. During operation, the operating functions of the machine are determined by the coding of the keys inserted in the key reader 34 shown in the block diagram of Fig. 1 and schematically illustrated in Figs. 9A, 9B, 9D, (not shown). The sequence of the functions can be determined merely by selective placement of appropriate keys in the desired operating order. The actual positioning of the machine is determined by the difference between a commanded position (as indicated on the control dials 36) and the actual position (as fed back to the comparator via the position transducers 30, 31, 32). This difference signal is first compared by digital techniques in order to effect a coarse positioning of the machine. When the difference has been narrowed to a small fraction of an inch, analogue techniques are used to effect an accurate final positioning. The dimensional data set into the control dials (52 in Fig. 5, not shown) is compared in a comparator 74 under control of a counter 75, 76, 77, with the actual position of the machine as indicated by the position transducers 32 that are mounted on the various traversing slides. The output from the comparator is representative of the difference between the commanded position and the actual position of the machine. This output is then used via amplifiers (e.g. 101, 97) and gate 93, to drive the machine in the appropriate direction to reduce the difference to zero. While the difference is large, digital comparison is used to determine the appropriate drive; however, when the difference becomes small, an analogue comparison is made to insure stopping the machine at the exact position desired.
