Title: Improvements in or relating to explosive pile shoes
IPC: E02D5/26
Filed: 1951-03-08
Abstract: 693,465. Piles. BLAKE, W. H. C. Feb. 8. 1952 [March 8, 1951], No. 5613/51. Class 68(ii) A concrete, metal or timber pile 1 provided at its lower end with a metal shoe 2 has a central metal tube 5, the upper end of which engages a plug 7 and the lower end engages a recess 6 in the point 4 of the shoe 2, the lower end of the metal tube being provided with an explosive charge 8 after the pile has been driven. On firing the charge 8 the lower end of the shoe 2 is partly burst and the cavity thus formed may be filled with concrete through the tube 5. The pile may also be driven further downwardly to increase the bearing area of the shoe. As applied to a concrete pile, a compressed fibre insulation joint 11 is cast integrally with the concrete so as to lie between the pile 1 and the charge 8.

Abstract: 540,091. Milling-machines. BUDD INDUCTION HEATING, Inc. March 28, 1940, No. 5642. Convention date, April 8, 1939. [Class 83 (iii)] [Also in Group XXIII] A machine for grinding or milling strip stock to give it a wedge. shaped cross section has a plane surface 86, Fig. 2, to support the strip stock 22 and a cutter 56 carried by a support 72, pivoted at 74, and adapted to form a plane surface on the stock, both of said surfaces passing through the axis 74. The support 72 can be adjusted laterally of the strip 22 by a hand operated screw 82 and a slide 76 and a scale on a shaft 96, on which a roller 92 is adjustably fixed centrally of the strip, is used to set the pivot 74 at any desired distance from the strip. Segments cut from the wedge-section strip thus formed from stock of varying section, but using one setting, can be assembled to form an annular transformer core of the radius to which the machine is set. The cutter may be a cup-shaped grinding wheel 56 and may be driven by a motor 58 and be horizontally adjusted by a handoperated screw 62. It is fed downwards, very gradually, by a screw 70, Fig. 4, worm-wheel 162, worm 160, gear 156, and a gear 154 having one or two teeth and driven by a roller 94 engaging the strip 22. The strip stock 22 may be fed by rollers 36, Fig. 1, driven by a motor 42, from a drum 20 and through hand adjusted tensioning rollers 24, wipers 26, a device 28 for smoothing the lower face of the strip, two machines 30, 32 as already described but oppositely arranged, for grinding two inclined faces 324, 318, Fig. 18, and a wiper 34. The finished strip is wound on a driven drum 44 and when cut to length for use in making cores is also divided longitudinally. The device 28 comprises a vertically adjustable grinding wheel 184, driven by a motor 186, adapted to press the strip 22 upwardly against a bridge 180. The strip may be held against the surface 86 and, if desired, the bridge 180 by suction. The tool may be held in contact with the strip by a vacuum operated cylinder 120, Fig. 2, and piston 124 connected to the slide 76 and support 72 respectively. In a modification a peripheral grinding wheel 240, Fig. 14, and a hardened supporting surface 238 are used. The wheel 240 is adjusted on its splined shaft 250 by a screw 290 arranged in a bore of the shaft and engaged by a radial screw of the wheel passing through a longitudinal slot 282 in the shaft.

Abstract: 668,790. Kinematograph apparatus. BAIN, P. March 7, 1950 [March 11, 1949], No. 5803/50. Class 97 (i). Continuous feed apparatus having an optical compensator oscillated or rotated about an axis at the centre of a curved film gate is characterized by a centred optical system between the compensator and objective which system, in a projector, produces a real image of the film frame to serve as an object for the objective, or, in a camera, forms on the film an image of the real image produced by the objective. The camera shown has an objective 18 and shutter 16 to form a real image at 20. A further. lens 13 forms a real image on the continuously moving film 4a, the mirror 8, oscillated by the cam 10, providing optical compensation. The film is fed by sprockets 5, 6 round the curved guide 3 in which is formed the aperture 7 longer than the height of a film frame. A shutter member 22, with an aperture 23, equal in size to the film frame, is oscillated in synchronism with the image on the film by a cam 24. A projector is described which is similar to the camera shown apart from the provision of a lamp and condenser to illuminate the aperture 7 and the fact that the shutter 22 is omitted and replaced by a fixed diaphragm to frame the image 20.

[Class 18] A locker into which articles can be delivered at house doors is provided with two openings 17, 18 of which one, the opening 18, has a door 18<a> normally spring-urged to the closed position, and an article placed on a platform 23 in the locker depresses the platform and prevents the door being opened. The opening 17 is closed by the house door so that the householder can obtain access to the contents of the locker when the house door is opened. The door 18<a> is in the shape of a semi-cylinder revoluble on pins 20 connecting the ends 19 of the door with the top and bottom of the locker, and springs 19A on the pins 20 urge the door to the closed position where an operating knob on the outer surface of the door abuts against one side of the opening 18.

Title: Improvements in and relating to electrical energy storage welding systems

Filed: 1942-05-04
Abstract: 556,733. Supply systems for resistance welding &c. BRITISH THOMSON-HOUSTON CO., Ltd. May 4, 1942, No. 5997. Convention date, May 2, 1941. [Class 38 (iv)] Thermionic and like control.-The energy stored in an inductance 4 is wholly or partly applied to a work circuit such as a welding circuit 1. The inductance is supplied with unidirectional current through two or more gas-filled discharge valves 6 ... 8 operating in sequence, and on reaching a predetermined current through the inductance the exciting potential 25 on control electrodes of the valves is replaced by a hold off voltage 19. To commutate the current in the valve, such as 8, which is then operating and is maintained conductive by the inductance, a precharged condenser 3a is connected in parallel with the valve 8 and inductance 4. The commutating circuit is -completed by the firing of a valve 33 which occurs when the supply potential from a transformer winding, such as 16, has brought the potential of a conductor 17 connected to the cathode of the valves 8; 33 sufficiently below that of the control electrode 34, which is connected to a negative bias voltage 36. The energy in the inductance is then discharged into the circuit 1.

Abstract: 467,754. Valve circuits for wireless reception. COLE, Ltd., E. K., and ROWE, H. C. March 2, 1936, No. 6207. [Class 40 (v)] In a superheterodyne receiver a low frequency amplifier valve is used as a local oscillator during tuning to produce a beat note in the loud speaker and the oscillating circuit is switched out when the receiver is operating normally. The switch is preferably actuated by the tuning knob of the receiver. The Figure shows an arrangement in which the valve V oscillates at or near the intermediate frequency when the switch 7 is open. Unless the intermediate frequency stages of the receiver are heavily screened special coupling means to the oscillating low frequency valve is unnecessary.
