Abstract: 318,334. Briscoe, A. June 27, 1928. Drilling-machines. - A combined drilling- machine and cramp comprises a hollow screw 9, Fig. 1, rotatable in a fixed nut 10, a movable jaw 6 and an adjustable fixed jaw 4, the whole being carried by a frame bar 1. The jaw 6 is engaged between the end of the screw 9 or a hand-wheel 15 attached thereto and a collar 13 on a drill spindle 11 rotatable within the screw. A hand crank 19 held by a nut 20 on the square end of the spindle serves for rotating the drill 14, the feed being applied by the wheel 15. When used as a cramp or bench vice the jaw 6 is moved by rotating the screw 9 from the crank 19 by means of a pawl 22, Fig. 4, slidable on the crank and pressed by a spring 28 into contact with notches in a flange 18 attached to the screw. The pawl is indexable by a pin 27 and notches 29, 30 in a bracket 23 through which the pawl is slidable in order to enable the screw to be rotated positively in either direction or through a right-hand or lefthand ratchet action by the crank 19. The movable jaw 4 is secured to the bar 1 by a screw 35 engaging notches 34 and this jaw and the nut 10 have feet 3, 5 for attachment to a bench. The flanges 7, 8 of the jaws are serrated, the flange 7 being perforated at 37 to admit the end of the drill after it has passed through the work, and a horizontal bifurcated flange 36 is provided on the jaw 4 for supporting the work being drilled or clamped. The nut 10 is gapped at 32 to clear the pin 27 when the screw 9 is fully advanced and a pin 33 on the screw limits its forward movements.

Title: Improvements in and relating to the starting control of electric winders
Inventor: PROWSE DONALD WINDSOR
IPC: H02P7/282
Filed: 1954-06-28
Abstract: 791,159. Control of A.C. motors; controllers. BRITISH THOMSON-HOUSTON CO., Ltd. June 13, 1955 [June 28, 1954], No. 18894/54. Class 38 (3). A winding motor is adapted to be supplied with A.C. for driving operation and with D.C. for braking, and a controller for the motor has a zero position in which the rotor resistance is at its maximum value, operation of the controller in either direction from this position decreasing the magnitude of the resistance. Clockwise movement of the controller provides power operation for lowering or braking operation during ascent of the motor-driven conveyance, whilst anti-clockwise movement produces power-raising operation or braking for lowering the conveyance. When the conveyance is stationary at the top of a shaft, the controller may be moved to the " lower " position to close contacts PL and also to release a brake, so that any lack of balance between the conveyance and its counter-weight will start a movement. If such movement is upward, a switch S then closes to excite relay coil c<SP>1</SP> and close contacts c whereby a field winding F of an amplidyne pilot motor is energized to drive the controller in a clockwise direction. The conveyance is thus driven downwardly. If the gravity-produced movement is in the downward direction, however, when the brake is released, the switch S will then excite coil cc<SP>1</SP> to close contacts cc, and so energize winding F that dynamic braking is introduced. When the conveyance is at the bottom of the shaft the operation will be opposite to that described. After the controller has been initially positioned in accordance with the direction of unbalance of the load, the starting circuit shown is opened and a control system of the type described in Specification 791,076 is made effective for the remainder of the winding operation. If the release of the brake is not followed by any gravity-produced motion of the winder, a timedelay relay becomes effective, after a predetermined period, to cause the motor to develop a torque for initiating motion in the direction determined by the setting of the master controller.

Title: Improvements in or relating to frequency-modulated distance measuring equipments
IPC: G01S1/02
Filed: 1954-06-28
Abstract: 752,718. Frequency-modulated radar. COM. PAGNIE GENERALE DE TELEGRAPHIE SANS FIL. June 28, 1954 [June 26, 1953], No. 18937/54. Class 40 (7). The frequency deviation of a frequencymodulated radio distance measuring equipment is calibrated by comparison of the time occupied by a predetermined number of beats produced by reflection from a reference beacon located at an accurately known distance, with the time of a corresponding number of pulses from a pulse generator controlled by a stabilized oscillator working at the correct beat frequency, the predetermined number being less than the number of beats produced in a modulation period of a correctly adjusted transmitter. A trigger device 5 trips a counting device 6 when the mixer output attains a predetermined instantaneous voltage value for the first time, and the device 6 then counts N-1 beats, where N is the number of beats produced by the beacon during a modulation period. The trigger device 5 also trips a stabilized oscillator 7 controlling a pulse generator 8. The (N-1)th beat from the counter 6 and the (N-1)th pulse from the generator 8 are fed to a time discriminator 9, the output voltage from which has a sign and magnitude depending respectively upon the order in which the two inputs succeeded each other and upon the time interval between them. This voltage thus provides a measurement of the frequency deviation. It may also be used as a correcting voltage for stabilizing the equipment at the desired frequency deviation. This method applies even when the total number of beats in a modulation period is non-integral, and is not affected by the discontinuities in the beat waveform at the beginning and end of a modulation period. A relatively small number of beats can, therefore, provide a high order of accuracy and enables the reference beacon to be located at a small distance (5 to 10 Km.) which can be the more accurately determined.

[Also in Divisions B2 and C5] Oil (non polar) is separated from water (polar) used for example in industrial lubricating operations by passing through the mixture a rotor in the form of a solid surface of revolution which has a surface which preferentially adsorbs the oil for it to be removed from the surface portion of the rotor not immersed in the mixture. The oil is adsorbed on roughened or grooved surfaces of rubber polytetrafluorethylene, polyethylene, neoprene, steel, iron, copper, aluminium, glass, acrylics. The rotor may be heated. A magnet may be incorporated in the rotor to remove magnetic particles. The oil may be removed by squeegee scrapers, squeeze type rollers or jets of air. Examples of rotors are given in Figs. 5-11 (not shown). The process may be reversed to adsorb the water on a hydrophilic rotor from a bath of oil.

Metal strip is rolled by passing it through a mill under tension and then through a second mill with a low tension so that little or no reduction takes place, the strip then being coiled under tension with any non-flatness of the strip removed. Bridle rolls 23 (Fig. 1, not shown) allow the strip to be coiled under tension without affecting the tension in the second mill 16. Tensiometers 25 measure the tension in appropriate regions and may be used in the control of the motors for the first mill 11, pinch roll units 15 and 16, and the rolls 23. The control may be automatic and include hydraulic piston and cylinder assemblies 19 which vary the pinch roll pressures. Conventional stands may replace the pinch roll units, the rolling being hot or cold, or alternatively, a planetary mill including a reducing roll co-operating with a fixed die may be incorporated. In an example low carbon strip of 40 inches x 0À016 inch section is rolled at 2000 f.p.m. and reduced only in the stand 11, the strip tension being 25,000 lbs./sq. inch leaving stand 11, 1,000 lbs./sq. inch leaving the unit 16, and 6,000 lbs./sq. inch between the rolls 23 and the coiler 24.
