Patent GB-549497-A (GB)
Title: Improvements relating to the centrifugal moulding of concrete pipes and the like
IPC: B28B21/34
Filed: 1941-05-21
Abstract: 549,497. Moulding and lining pipes in centrifugal machines. HUME, W. R., and HUME PIPE CO. (AUSTRALIA), Ltd. May 21, 1941, No. 6542. [Class 87 (ii)] The end plates 3 have central annular flanges 6 of small diameter which rest upon rollers 7 and so support the mould that the centre of gravity of the mould is lowered. The end plates have a series of circular rows of bolt holes (not shown) whereby mould casings of different diameters may be attached thereto. The end plates may project beyond the casing 3 and may have heavy rims which strengthen the plates and impart a flywheel effect thereto ; these heavy rims may contact with mechanically or hydraulically intermittently-operated jolting rollers to compact the semi-dry concrete mixture in the casing. Alternatively, the jolting may be effected by means of (a) stepped end plates engaging rollers, or (b) a stepped cam or wheel 9 which engages the bare rims of the plates 3 and is adjusted by a screw device 17 via link 16, arm 14 and eccentric 11. The flanges 6 define a central aperture through which extends a hollow shaft 19 secured by brackets 21 to levers 23 pivoted at 24 on brackets 26 on the main frame 5. Arms 27, 44, extending from the shaft 19, carry respectively a screeding roller 18 and a screeding bar 42. The roller 18 may be locked at each end against rotation by inserting the keyed end 34 of a locking spindle 33 into a recess 35 in the roller ; this insertion is effected by fitting a crank handle to the slotted end 39 of a shaft 38 and rocking the latter so as to depress the spindle 33 by means of a link 37. The spindles are held in their raised, retracted position by spring catches 40.- The arms 44 carrying the screeding bar 42 are pivoted on the shaft 19 and are rigidly connected to the arm 27 by a pin-and-slot connection 45, 46. Ropes or chains 51, 51a connect the bar 42 and pin 46 to a winding spindle 48 by means of which, after an initial screeding has been effected by the bar, the pin may be withdrawn and the bar raised to allow the roller 28 to operate alone. Downward pressure may be exerted by the levers 23 on the concrete through the medium of the screeding members. The casing is driven by means of bands 54 passing therearound. By securing the end plates to a metal or other pipe, the pipe may be lined.

Title: Improvements in gas supply apparatus for supplying gas at a controlled rate to flowing liquid
IPC: C02F1/76
Filed: 1938-03-02
Abstract: 504,415. Fluid - pressure servomotor-control systems; purifying liquids. BOOTH, G. M. March 2, 1938, No. 6588. [Class 135] [Also in Group I] The invention relates to controlling means for a water aspirator 13 sucking a stream of gas, such as chlorine, along a pipe 17, the two streams mixing together. The aspirator suction is maintained slightly in excess of that required to suck the gas through a restriction 12, water pressure being used to control the position of a regulating valve 19. Gas in the pipe 10 is approximately at atmospheric pressure. The valve 19 is connected by a rod and tube 27 to a diaphragm 22, which is pressed downwards by a light spring 25, and upwards by water in a chamber 30, which is fed from the main 51 through pipes 72, 80 and a regulating valve 32. Water flowing from the chamber 30 past a valve 47 flows up the tube 27 into a chamber 15. A float 20 is attached to a valve 43 which regulates the flow of water from the tube 27. A water-tight diaphragm 23 is provided. Water is discharged from the chamber 15 through a pipe 33 and overflows into a chamber 40 from which it flows to waste through a tube 41. The level of the outflow 35 is maintained at the normal operating level of the water within the chamber 15 so that the vacua in the chambers 15 and 40 is the same. Air from a pipe 44 bubbles through the water in 40, and is carried away with the water in pipe 41. When no water is passed to the chamber 30, the spring 25 presses down the diaphragm 22 to close the valve 47 and thus the tube 27. When a greater vacuum than necessary exists in the chamber 15, the water level rises, the float 20 closes the valve 43, and pressure (due to water supply) rises in the chamber 30 causing the diaphragm 22 to move upward to give a closing movement to the valve. 19, thus reducing the vacuum in 15. The upward movement of 22 opens valve 47. The supply of water to the aspirator 13 is controlled by a valve 56 and a diaphragm 58. A piston 59 seals the upper side of the diaphragm from the valve chamber. Water passing through a pipe 62 is fed through a regulating valve 63 into a pipe 64, past a valve 65 and through a waste pipe 66. If a lever 72 rises, the valve 65 is closed and pressure builds up under the diaphragm 5 to partly close the valve 56 and thus restrict the amount of water passing up the pipe 52. The pipe 62 also supplies a small quantity of water to a container 71 whence it passes up a small bore tube 70 into the pipe 17. A spring 75 presses upwards the lever 72 to close the valve 65 when the container 71 is empty. A diaphragm 76 is under pressure of water in the pipe 52, and tends to lift the lever 72 through a rod 77 against the weight of the water in the container 71. In a modified arrangement, the container 71 is detached from the lever 72, and contains a float which is hung from the lever. The tube 44 may be dispensed with, and a pipe led to the chamber 40 to control the vacuum therein.

Abstract: 511,837. Controlling motor-vehicle engines; pedals. RUBISSOW, G. A. Feb. 19, 1938, No. 6594/37. [Classes 79 (v) and 136 (ii)] The throttle valve of a motor vehicle engine is controlled by a sliding member g, Fig. 1, on which the driver's foot rests, the friction between the member g and the floor board b being sufficient to resist the thrust of the throttleclosing spring. In the construction shown in Fig. 1 the slide g bears against a roller d on the throttle lever l. A spring h, additional to the usual throttle-closing spring (not shown) may be provided tending to move the slide to the closedthrottle position. The friction between the slide g and the floor may be increased by springs or electromagnetic means, or one or both of the contacting surfaces may be corrugated or provided with frictionincreasing or reducing material. In the construction shown in Fig. 8 the slide g acts as a wedge between the throttle lever l and a fixed guide p. Alternatively the guide p may be resiliently mounted. The slide g may act directly on the lever l as shown in Figs. 1 and 8 or may operate it through a sector, a link, or a cable or spring.

March 6, 1933, No. 6779. Convention date, March 5, 1932. [Class 40 (v).] In a frequency changing circuit, a modulation product of a frequency stabilised oscillator 14 and a tunable oscillator 27 is injected into the circuit of an oscillating detector 69. Received signals, amplified at 64, are mixed with the local oscillation injected by a coil 10 and the intermediate frequency taken from the output of the oscillating detector 69. The local oscillation is obtained by modulating the oscillations from a crystal controlled oscillator 14 with the oscillations from a tunable oscillator 27 by a valve 41 whose output circuit is tuned to the desired difference frequency. Preferably the oscillator 14 generates a harmonic of the crystal frequency and the frequency of the oscillator 27 forms a minor part of the heterodyning frequency, e.g. is not greater than half the frequency of the oscillator 14. Specifications 407,933 and 407,934 are referred to. According to the Specification as open to inspection under Sect. 91, the detector 69 need not be an oscillating detector.
