Filed: 1929-08-14
Abstract: 317,484. Walter, G. Aug. 18, 1928, [Convention date]. Centrifugal machines; shaking and jigging machines.-In the manufacture of concrete pipes &c. by centrifugal and jigging actions, the jigging mould is lined with a filter and first rotated at low speed to distribute and consolidate the material and drive the water towards the interior, after which the speed is increased to drive the liquid outwards through the pores of the partly consolidated pipe and thence through the filter, where it escapes. The mould is vibrated with different frequency and amplification during the stages. A divided mould 11 formed of perforated metal and lined with filter cloth is supported by rings 10 on pairs of rollers 12 carried by shafts 13, one of which is driven by a motor 14. The shafts and motor are carried by a frame 19 suspended in frames 20 and adapted to be vibrated by mechanism 21. Upper rollers 17 retain the mould. In operation, the mould is rotated at low speed and vibrated and is charged with material. After distribution of the material the vibrations are reduced or stopped and the speed of rotation is, increased to drive out the liquid through the filter. To prevent splashing, the mould is enclosed by a cover or is surrounded by a second casing. During the second stage, suitable impregnating liquids may be introduced into the mould. The filter may comprise a woven fabric of jute, cotton, &c., or may be dispensed with by slitting the metal of the mould. After driving out the liquid the mould is removed from the apparatus and the pipe &c. separated from the filter which is replaced in the mould. Vibration may be imparted directly to the mould. '

Title: Improvements in or relating to focussing arrangements for electron beam tubes
IPC: H01J37/14
Filed: 1963-06-25
Abstract: 1,049,875. Travelling wave tubes. WESTERN ELECTRIC CO. Inc. June 25, 1963 [July 3, 1962], No.25142/63. Heading H1D. A travelling wave tube has a magnetically shielded cathode and an electron gun for producing a converging electron beam, the resulting electron beam being focused by a magnetic field which has a strength higher than that required for Brillouin focusing whereby the beam is caused to commence to scallop, the focusing field being distorted to produce an imbalance of the forces governing the flow of the beam so as to produce a cancellation of the scalloping effect of the focusing field. The focusing field is five or six times larger than that required for Brillouin flow at the point of entry of the beam into the focusing field, and the distortion of the focusing field is at a point from the place of entry of the beam into the focusing field e.g. between “ and ¢ of a scallop wavelength such that the beam is compressed to the Brillouin diameter corresponding to the focusing field. The field distortion is a decrease in the strength of the magnetic field over a distance of up to ¢ a scallop wavelength. The focusing field is preferably produced by a period permanent magnet system, and the magnet field distortion is produced at every field reversal to eliminate scalloping, the field being distorted both before and after each field reversal. The field distortion is produced by a ring of magnetic material.

[Class 120 (i).] Slip rolls on which laps are wound as in exhaust - opener lap machines, cylinder - opener lap machines, scutcher lap machines, &c., are uniformly "weighted" by means of adjustable dead weights on the rack bars, the latter, as the lap is built up, operating through a gear train to overcome a frictional force which holds the rack bars in any desired position. The rack bars can also be lifted higher for doffing the laps by means of a hand-wheel which operates through the gear train. A slip rod r is held by guided rack bars 1 which are separately and equally loaded or have, at their lower ends, slotted brackets to hold between them weights 4 in the form of bars notched at the ends. The teeth on the rack bars engage with pinions 6 keyed on a shaft 5 which also supports a sleeve 7 to which are keyed a pinion 8, a friction wheel 9, and a hand-wheel 10. The remainder of the gear train connecting the pinions 6, 8 consists of a pinion 17, compound pinion 14, and pinions 11, 13, keyed on the same shaft. The rack bars are raised for the removal of a completed lap by turning the hand-wheel 10 which operates through the gear train, and the rack bars are held in the raised position by a brake block 22 acting on the wheel 9. The brake block is in engagement with the wheel 9 while the lap is being wound and also while the rack bars are being raised. When the brake block is released by pressing on a treadle lever 18, the gear train allows the rack bars to run down slowly. The lever 18 is pivoted at 19 and carries an adjustable weight 20.
