Title: Improvements in or relating to shutting off devices and valves
IPC: F16K17/34
Filed: 1923-05-23
Abstract: 198,666. H³bner & Mayer, and Roschanek, O. May 31, 1922, [Convention date]. Valves closing with rush of fluid.-An automatically closing valve is arranged so that when the valve is moved towards its seat, consequent on a rush of fluid, fluid is admitted to a cylinder to retard the closing movement and so prevent hammering. In the form shown in Fig. 2, the main valve member 1 is formed integrally with a subsidiary valve face 2 adapted when the main valve moves towards its seat to allow pressure from the main conduit to act on a braking piston 6. Part of the pressure so admitted escapes to atmosphere through a valve-controlled passage 11 and the excess passes between the piston and the cylinder to an annular chamber in a member 9 and thence to the actuating chamber of a safety valve or other apparatus. The escape passage 11 may be formed in the casing and a hand-actuating lever may be fitted. The subsidiary valve and piston may be connected to a lever carrying the valve or an oscillating vane for actuating the valve. In order to give a progressive braking action, the piston may be normally clear of the cylinder, may co-operate with a tapered chamber, or may be stepped to work in a stepped chamber. In the form shown in Fig. 10, the braking cylinder communicates with the fluid conduit through a restricted valve-controlled passage 44 and through larger grooves 5 in the spindle which are closed as the main valve moves towards its seat. In the form shown in Fig. 7, the main valve has a skirt adapted to cooperate with a boss 26 to reduce the supply to the braking chamber as the valve rises. The main valve can be closed by admitting fluid pressure through a control valve 31 to the space below a spring-loaded piston 29, which space is provided with a valve-controlled leak 33. A second piston 35 is arranged below the piston 29 working in a chamber provided with an adjustable leak 37 and wiper connected by a pipe 36 with the other automatic valves on the system so that they all may be closed simultaneously. The Specification as open to inspection under Sect. 91 (3) (a) describes also combined stop and check valves fitted with rotary valve or reciprocating piston dashpots. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in concrete floors, ceilings and the like
IPC: E04B5/36
Filed: 1938-05-07
Abstract: 510,749. Concrete floors. FORMETA-BETON ATKIESELSKABET, and BRANDT, J. May 7, 1938, No. 13703. [Class 20 (iv)] Relates to a unit for use in casting concrete floors and adapted to be left in the finished construction so that its undersurface may serve as a base to support plaster or like material constituting the ceiling. According to the invention, the unit comprises forms 3 of inverted-V or arch shape which are mounted on a base 1 by means of spaced laths 2 engaging the edges of the forms and secured to the base. The base 1 comprises a number of boards which are spaced slightly apart and connected by the laths 2. The forms, which may be of plywood, are adapted to be sprung into position between the laths 2 so as to have a non-integral connection therewith. The units shown in Fig. 3 are anchored to the concrete 5 which is cast over the units by bolts 6 mounted in the laths 2. The joint between two abutting units may be covered by an arch member 8, Fig. 3, or the end laths on these units may be disposed in contact. The plaster ceiling 7 may be applied to reeds mounted on the base 1. In the modification shown in Fig. 5, the head 12 of the anchor bolt 6 is disposed between two insulating and yieldable discs 13, 14 mounted in recesses in the board 1 and lath 2; the shank of the bolt 6 passes through a hole 15 in the lath, and an insulating and yieldable strip 16 is placed over the lath The strip 16, which, during casting of the concrete, is somewhat compressed, expands after removal of the supporting means for the unit and tends to separate from the concrete. When the forms are of inverted-V shape, two or three of such members may be disposed on a single base. The spaces between the forms and the base may be filled with insulating material.

Title: Improvements in or relating to the shaping and vulcanizing of pneumatic tires and the like
IPC: B29D30/06
Filed: 1943-08-23
Abstract: 571,287. Moulding and vulcanizing "pulley-band" tyre blanks. McNEIL MACHINE & ENGINEERING CO. Aug. 23, 1943, No. 13719. Convention date, Nov. 4, 1942. [Class 87 (ii)] The diaphragm 12, which serves the dual purpose of shaping the " pulley-band " blank B into tyre form and acting as the curing bag, is clamped at its edges to the flanges of a stationary double-bell-shaped member 15 which is secured to the lower mould section by a pipe 27 and nut 26. In use, with the parts in the position shown, the upper mould section 2 descends and the blank B bows outwardly, this bowing action being assisted by pressure air from pipe 27. As the upper mould section approaches the closed position, the air pressure from pipe 27 is released and superheated water under pressure is admitted through pipes 33, 29 to the chamber formed between the diaphragm and the member 15. This water pressure expands the diaphragm and forces the blank into tyre form against the mould walls. After curing, the water connections are turned to exhaust, and finally the diaphragm is sucked out of the tyre by vacuum through pipes 29, 34. Either or both of the mould sections may be movable. Specification 554,858 is referred to.

Title: Improvements in or relating to Mercury Vapour Lamps.
Inventor: CORNU MARIE JOSEPH
IPC: H01J61/54
Filed: 1917-09-25
Abstract: 129,022. Cornu, M. J. Sept.. 25, 1916, [Convention date]. Arc lamps.-A thickwalled silica tube, which is full of mercury when cold, communicates with a closed cathode pocket and an anode pocket in which movement of the mercury is strongly damped by a valve. The thickness of the wall of the arc tube is at least half its internal radius. Cooling-bulbs b, e, the latter of which may be provided with radiating-gills, are interposed between the lighting-tube i and the electrode pockets. A tube d. the narrow end of which projects into the middle of the anode bulb c, is covered by the lift valve g depressed by a coiled leading-in wire h. The working pressure in the lighting tube is predetermined by regulating the height of the mercury in the anode bulb and the initial gae pressure, but is always greater than atmospheric pressure. If the anode bulb is sealed, the gas pressure varies automatically with the electric pressure. Starting may be effected by heating the mercury-filled lighting tube i at its upper bent end k by an external gas flame or series coil of platinum. Alternatively, a capillary tube may lead upwards from the bend k to a bulb containing a series, shunt, or independent heating-coil, or to a cylinder and spring-urged piston which can be depressed either by hand or by automatic electric means to force nitrogen, argon, neon, or a vapour into the arc tube.

Title: Improvements in or relating to stroboscopes
IPC: H05B41/34
Filed: 1960-04-20
Abstract: 875,057. Electric motors. GREINER ELECTRONIC A.G. April 20, 1960 [Feb. 15, 1960], No. 13816/60. Class 35. [Also in Groups XX and XXIV] The stator and rotor of a stroboscope synchronous motor are mechanically coupled by an adjustable infinitely variable gearing to cause rotation of the stator whereby the rotor shaft carrying a slotted stroboscope disc is capable of variation in speed, this variation, with respect to the rotor speed with the stator stationary, being an indication of the difference in frequency between signals, applied to the stroboscope flash and the stator windings. As shown, the stator 15 is rigid with the motor housing 17 rotatable in bearings 19 and 20 in the stroboscope frame coaxially with the rotor shaft 13 which carries a disc 31 frictionally engaging a wheel 29 the rotation of which is transmitted, with a speed reduced by a factor of about 200, via worm 28, shaft 25 and gear-wheel 26, to a gear-wheel 21 fast with the rotatable housing 17. If signals of slightly different frequency are applied to the stator windings 16 via leads 24 and to the flash lamp 7, an illuminated slit in the disc 11 carried by the rotor shaft 13 will appear to rotate slowly. By means of knob 41, a cam 38 can be made to move shaft 30 against spring loading 39 whereby wheel 29 can be adjusted to engage disc 31 at varying distances from its centre whereby the speed ratio of stator rotation to rotor rotation can be varied from 0 in either direction to a factor of about 0.003 until the slit appears stationary. A scale provided for knob 41 can be calibrated to indicate the frequency difference of the two signals.

Title: Improvements in or relating to systems for measuring distances by the use of electromagnetic waves
IPC: G01S7/282
Filed: 1944-07-19
Abstract: 638,272. Radio-location ; pulse generating circuits. RAYTHEON MANUFACTURING CO. July 19, 1944, No. 13868. Convention date, Jan. 24, 1939. [Classes 40 (vi) and 40 (vii)] In a pulse radar system having a cathoderay tube display, the transmitter is triggered by pulses generated by a second cathode-ray tube operated in synchronism with the display tube. In Fig. 1 phase-quadrature voltages from the oscillator 10 are applied to the deflecting plates of the modulator and indicator cathode-ray tubes 9 and 12 to produce synchronous rotating electron beams. The rotating beam of the modulator cathode-ray tube impinges on a narrow electrode 13 once per revolution to give a sharp pulse which is applied through the amplifier 8 to trigger the transmitter 3 causing it to radiate a directional beam from the aerial system 4. Echo pulses from the receiver 27 are fed through the amplifier 28 to the grid 34 of the indicator cathode-ray tube 12 to produce bright responses on the normally blacked-out circular trace or dark responses on a normally brilliant trace, the position of the responses on the circular scale 11, Fig. 2, indicating the distance. Alternatively the responses may produce a serration in the trace. The echo responses may be increased by increasing the radiated pulse width and distances less than the pulse width may be measured by observing the position of the leading edge of the echo pulse or by deriving a sharp pulse from the received signal. In such cases the receiver must be completely screened from the transmitter and this may be obtained in an airborne installation by locating them on opposite sides of the fuselage. 'The aerials may be located in parabolic reflectors which are placed in the wings, the apertures being flush with the wing surface, Fig. 4 (not shown), and one set of aerials may be located under the wings for use as an altimeter and another set may be located in the leading edge of the wings for use as an object locator.

Filed: 1966-03-30
Abstract: 1,146,901. Making gears; bending. LEAR SIEGLER Inc. 30 March, 1966 [21 June, 1965(2)], No. 14101/66. Headings B3A and B3E. Ovality of an annular member, such as an internal gear G, is corrected by applying radially directed outward or inward forces to the member so as to stress it beyond its elastic limit, producing relative rotation between the points at which the forces are applied and the member, and then reducing the radial forces whilst maintaining the relative rotation. Outwardly directed forces are applied by a pair of pinions 20, 22 journalled on shafts 26, 44 which are supported by pairs of arms 32, 48, Fig. 5, which can be driven apart by a cam 52 on a shaft 54, Fig. 3, which is rotated by fluid pressure means acting on an arm 62 to force the pinions into contact with the gear G deforming it outwards. The pinions 20, 22 are then driven by a pinion 24, causing the gear G to rotate and after it has completed at least one complete revolution the force exerted by the cam is gradually reduced. After this treatment the ovality of the gear is reduced and the gear teeth are burnished. Additional inward radial force may be applied by a pair of rollers 108 which are mounted on a yoke 96, Fig. 8, and are a predetermined fixed distance apart such that when the yoke is pushed over the gear G by a screw 88 or by fluid pressure operated means the gear is deformed inward. Gradual reduction of the inward force is produced by withdrawing the yoke 96 from the gear G.

Title: Improvements in brakes for road vehicles
IPC: B60T13/06
Filed: 1923-03-28
Abstract: 222,418. Royce, F. H. March 28, 1923. Actuated by running axle or shaft; hand and foot actuation; force-transmitting mechanism.- In brake mechanism for road vehicles of the kind comprising a rock shaft connected to a brake and adapted to be actuated by a running shaft of the vehicle through a friction clutch device but which is effective only during forward travel of the vehicle, a stop is provided to limit the reverse movement of the driven member of the clutch so that interference with the direct application of the brake during backward travel of the vehicle is prevented and a braking effect is obtained from the clutch itself. The stop is shown as embodied in the brake mechanism described in Specification 222,162 in which the actuation of a single hand lever or pedal is arranged to apply brakes directly to one pair of wheels of a vehicle and to engage a friction clutch which applies brakes to the other pair of wheels. The plate c' keyed on the driven shaft c of the clutch device is provided with dogs c<8> which project between corresponding dogs on a fixed part c<1>. When an arm e<5> freely mounted upon the shaft c is actuated, spiral serrations on the sleeve e<5a> which carries this arm engages corresponding serrations on the boss e of an arm e<3> connected to the brakes on the front wheels. The arm c<3> is thus turned to apply these brakes and the sleeve e<5a> is also displaced longitudinally on the shaft c thereby effecting the engagement of the clutch discs c<6> by means of the rod f<3> and presser member f. The driven shaft c of the clutch is thus turned and if the vehicle is travelling forwardly applies the brakes on the rear wheels by the arm d. If the vehicle is travelling rearwardly the rotational movement of the shaft c is arrested by the dogs c<8> and the braking effect of the clutch discs is still added to that of the brakes applied directly by the driver.
