Abstract: 325,093. Formunt, J. A. Feb. 7, 1929. Piers; walls; piles, driving. - Sub-structures are placed below a pier or a like structure by inserting a caisson laterally under it, and maintaining the air pressure in the caisson; inside this sectional piles are driven so as to support the pier &c., and the caisson is finally filled with concrete. In preparation for underpinning the pier 1, a temporary pile 4 is driven equidistant from two piles 3 supporting the pier. A caisson consisting of a top plate 5 preferably of non-corrodible steel, a leading wall 6, and two side plates is lowered until the wall 6 is beneath the raft 2, and the chamber 9 and air-shaft 10 are attached. Compressed air is then forced in, and the soil under the wall 6 is removed. The caisson 5 is then gradually thrust forward by a winch 12 and rope 13, or by hydraulic or other means, the pile 4 and a cross-beam 28 being utilized for this purpose. The pile 4 is then cut down, and a permanent pile 16 utilized. These permanent piles consist of tubular sections of metal or concrete, and are pressed down in succession by a hydraulic ram 17, set between the roof 5 and the pile.' The earth &c. having been removed from the interior of the pile, it is filled with reinforcements and concrete. A packing-piece is then placed under the roof 5 and above the pile, and the space between the pile and the packing-piece is filled by fitting an inverted cup over the top end of the pile, end filling it with grout under pressure. When all the piles are driven and the load transferred to them, the whole of the caisson, except the chamber 9, is filled with reinforced or other concrete. When this is set, the shaft 10 and other parts are removed. The apparatus may be used to raise structures which have subsided.

[Also in Group XXVIII] A tubular piston and cylinder engine operable by a gaseous medium, particularly for operating doors, and comprising a doubleacting differential piston and cylinder having means for cushioning the piston when approaching the end of both its strokes, has a first valve carrier 9 slidable within the hollow interior of the piston-rod 2 and urged by a spring 10 to a position projecting from the large area side 27 of the piston 20, a second valve carrier 16 encircling the piston-rod and urged by a spring 17 to a position projecting from the small area side 19 of the piston in the opposite direction from the first valve carrier, and valve members 8, 18 carried by the respective carriers and arranged to co-operate with respective main outlet openings so that over a terminal portion of either stroke only a restricted opening is left for the escape of the gaseous medium, whereby the piston is cushioned over each terminal stroke portion by compression of both the gaseous medium and the spring associated with the operative valve carrier. The engine is shown at the limit of its inward stroke, the valve member 8 being biased against its seating by a spring 14 and the main supply pressure being applied to the port 5. When, by means of a manually-controllable magnet valve or otherwise, the pipe 13 is connected to the main pressure, the valve member 8 lifts from its seating and the pressure is applied to the large face of the piston via ports 26 in the carrier tube 9 so that the piston begins to move outwardly. The gaseous medium in the space 36 exhausts to the port 5 through an annular passage between the piston-rod and the cylinder end 4 until this is closed by the valve 18 after which restricted exhaust takes place through an adjustable choke valve 6. When the main pressure is removed from the pipe 13 the valve member 18 lifts from its seating against the bias of a spring 31 and the inward stroke commences, continuing unchecked until the valve member 8, which has been withdrawn from the end of the cylinder by the engagement of the piston with an abutment 29 on the tube 9, again closes the main outlet 12. Restricted exhaust then takes place through an adjustable choke valve 15.

Abstract: 395,443. Pressure-regulating valves. PARKINSON, B. R. and PARKINSON & COWAN (GAS METERS), Ltd., 7, Fitzalan Street, Kennington, London. Feb. 22, 1932, No. 5243. [Class 135.] A gas governor for maintaining constant a slight vacuum in the conduit by which gases are withdrawn from a carbonizing plant has a valve member 6 in the form of an open-ended cylinder dipping at its lower end into a liquid seal and co-operating at its upper end with a dished removable seating 4 supported by a flange 5. The valve member is connected by a spider 19 and spindle 18 with a strap 23 passing over an arcuate surface 24 on a see-saw lever 21, while another strap 26 passing over the other end of the lever is secured to a liquid-sealed bell 22. The spindle 18 has flats 18a where it passes through guide discs in a sleeve 17 secured to the valve seat and carries a bell 20 adapted to co-operate with the sleeve 17 to form a leakage preventing seal. A similar spindle 32 with flats 32a is secured to the actuating bell and co-operates with a guide sleeve 33, provided at its lower end with a drain cock 34. Sealing liquid is supplied to the tank 1 through a conduit 12 and level indicator 13. Overflow from the tank 1 passes down the tube 17 to a tray leading to channels in the spider arms whereby it is directed to the seal for the valve member. This may be replaced by an overflow pipe leading directly to the lower seal. Overflow from the lower seal escapes through the outlet conduit 10 or through an overflow pipe 15 provided with a liquid seal 16. Accumulation of tar may be run-off from the lower seal through a drain 11. The cover 29 may be loosely fitting to permit atmospheric pressure to act on the upper surface of the bell or it may be made fluid-tight and a loading pressure admitted through the conduit 36. In the latter case the loading pressure may be controlled from a distant point by a small auxiliary gas governor, Fig. 2. This governor comprises a hinged valve 54 coupled by an arm 51 with the guide spindle 49 of a liquid sealed bell 43. The inlet 38 is connected to a source of clean gas, and the outlet 39 to the nearest vacuum main while the pipe 55 opening beneath the bell is connected to the space above the main bell. According to the Provisional Specification the auxiliary governor may be arranged to control the actuation of the main governor by controlling the pressure admitted beneath the main bell. Hunting of the main governor may be prevented by inserting a short length of pipe having a restricted bore in the control conduit.
