Abstract: 502,602. Concrete piles. BALDUZZI, A. Sept. 21, 1938, No. 27570. [Class 68 (ii)] Concrete piles are cast-in a closed sectional tube which riaes as concrete is forced in under pressure, means being provided for maintaining pressure by air on the concrete already in position when a top section is being taken off. The tube consists of a number of sections 1, 1, adjacent sections being screwed into a connecting piece 27 having a. slidable closing plate 30. adapted to separate the tubes when in position, so that concrete can be supplied to the lower tube through a passage, not shown, while pressure may be maintained at all times by air supplied through the openings 32, 32<1>. As the pile is built up and the length of tube rises, the next lowest connecting piece 27 is exposed. The slide holder 34 and,adjustable ring 24 are rotated until the slots 23, 25 in the connecting piece 27 and ring 34 respectively coincide when the slide 30 can be pushed in. The next upper section 1 can then be removed and the building of the pile can proceed. As the tube continues to rise, sections are removed as they come above ground.

Title: An apparatus for preventing shading in machine-made lace
IPC: D04C5/04
Filed: 1919-11-12
Abstract: 158,398. Barker, J. G. Nov. 12, 1919. Lace machines.-To obviate the defect known as " shading " caused by stopping a lace machine at intervals, each stop causing a line across the work, the warps are automatically tightened up by lowering the warp beam bodily each time the machine is stopped and are retained in this condition until the machine is started, whereupon the warps are slackened to the original state by raising the beam. The bearings A for the beam B are carried by or formed in levers C, the rear ends of which are jointed to the lower ends of links D suspended from the fixed framing E. The fore ends of the ievers C are formed with or connected to screw-nuts C' mounted on the screwed parts G' of vertical shafts G mounted in fixed bearings H, H<1>. The upper ends of the shafts G carry spur-wheels L meshing with racks K disposed on a rod J which extends the length of the machine and is connected to the ordinary starting and stopping gear. When the rod J is moved in the direction to stop the machine, the beam B is lowered to tighten the warps, and ratchets M carried on the end faces drop on to fixed pawls N which prevent the warps from being let off owing to the additional tension put on them. When the rod J is moved to start the machine, the beam is raised, thereby releasing the ratchets M and slackening the warps.

Abstract: 503,858. Cathode-ray tubes; light valves. FERNSEH AKT.-GES. Oct. 15, 1937, No. 28099. Convention date, Oct. 15, 1936. [Classes 39 (i) and 40 (iii)] A cathode-ray tube for television purposes has a number of elementary light valves 1 which are displaced as a consequence of scanning by a modulated beam, the charge on each elementary valve remaining substantially constant for a time approximately equal to a complete frame ; they are subjected to a second scanning to return the charge to a datum value and allow the valve to occupy its undeflected position. The same or a second beam may be used for the two scanning operations. Each valve may be mainly of nickel and carry a carbon surface 4 ; a suitably biassed grid 3 is placed near the valves to hold them in their deflected positions. The first scanning by a modulated beam takes place over the carbon surfaces and the charges obtained on the valves gives variable deflections ; the second scanning takes place over the nickel surface and returns the valve charges to datum. Other combinations of materials such as nickel, copper, aluminium and silver having differing secondary-emitting properties may be used. If a wide enough scanning spot is used, the same beam as it deflects one row of valves may be incident on a lower row to obtain datum values. A single material surface may be used with scanning beams of different velocity or intensity. The device may work with complete extinction of light with a valve element in its deflected position.
