Abstract: 658,532. Dashpots. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 4, 1949, No. 6034. [Class 108 (iii) ] A liquid dashpot comprises a piston movable within a cylinder which communicates, through restricted passages on opposite sides of the piston, with a pair of chambers of variable volume, the resistance to liquid flow of each of the restricted passages being greater than that of the transfer path by which liquid is transferred past the piston in the operation of the dashpot. In the arrangement shown, a piston 8 is secured on a piston rod 9 between tubular members 10, 11 and is movable between a pair of flanged discs 1 and 2, spaced apart by an annular member 3 and forming the dashpot cylinder. The latter communicates with a pair of variable volume chambers, which are interconnected by a balance pipe 15, through restricted passages 12 and 13 the restriction ofeach of which is greater than that of the restriction between the piston and the annular member 3. The chambers are formed by tubular members 16 and 17, annular end discs 18 and 19 and bellows 22 and 23 of which the opposed ends are closed by discs 20 and 21 secured to the piston rod and to the respective members 10 and 11.

Abstract: 1427283 Reciprocating conveyers DAVY-LOEWY Ltd 23 Jan 1975 [11 Feb 1974] 06177/74 Heading B8A Apparatus for transferring a workpiece horizontally between two positions comprises a wheeled carriage 9 supported on an H-section beam 1 and attached at its ends to a cable 12. The cable passes around pulleys 6 mounted on the beam 1 and has a peg 15 positioned in a bracket 17 secured to a foundation. The beam is supported on rollers 3 of bell crank levers 18 for raising and lowering by means of a cylinder device 22. The beam is horizontally movable by linkage 7 and a cylinder device 8. Beams or roller tables 23 are provided on either side of the beam 1. To move the carriage along the beam 1 between a first position and a second position it is only necessary to displace the beam a distance which is less than that between the first and second positions because in addition to the movement of the carriage due to the movement of the beam, there is further relative movement between the carriage and the beam. The stroke of the cylinder device 8 may thus be less than would otherwise be required. In use, a workpiece may be lowered on to the carriage 9 and, after displacing the carriage along the beam 1, the workpiece is lifted from the carriage. Preferably, however, after a workpiece is positioned on the supports 23 and overlying the carriage, the beam 1 is raised by operating the cylinder device 22, the carriage 9 and workpiece are raised and the workpiece, being clear of the supports 23, is moved longitudinally of the apparatus. The workpiece having been lowered on to the supports 23 by retraction of the cylinder device 22, the beam 1, by actuating cylinder device 8, is returned to its starting position. For large workpieces there may be a plurality of the illustrated constructions side-by-side. Instead of the bracket 17 being stationary it may be displaceable in the direction of the length of the beam.

Abstract: 574,552. Combustion-product plant. HALLOWELL, E. April 24, 1943, No. 6599. [Classes 7 (i) and 7 (ii)] [Also in Group XXVI] Relates to an explosion engine which supplies separate successive high pressure gas columns to a discharge conduit of predetermined dimensions, thedischarge conduit having a restriction forming a point of oscillatory rebound for the gas columns and setting up a back pressure dependent on the initial energy of the: columns and in which the gas columns operate in a manner analagous to pistons in exercising scavenging, charging and compressing functions. According to the invention, the oscillating gas columns are propagated-beyond the point of rebound, in their depression phase induce air &c. into the system and in their pressure phase may force air into the combustion space to effect supercharging. Charges of combustible mixture or of air fed through a ring of inlet ports 3 to a double-acting cylinder 1 oscillate a free piston therein and at maximum pressure part of the burnt charges is exhausted through a restricted passage 22 into a conduit 25. The conduit 25 leads to a restriction 24 which throws the discharged gases into oscillation and the oscillations serve to draw out from the cylinder 1 the remaining burnt gases which pass through exhaust ports passage 23 between the inlet ports and the ends of the cylinder, to enter the conduit 25. The restriction 24 is formed by a convergent-divergent section of the conduit 25 and beyond it an air inlet passage 28 controlled by light non-return valves 29, opens into the conduit, the oscillations of the gas columns drawing air into the conduit during phases of depression and driving it out during pressure phases through valves 30 leading to the inlet ports 32 of the combustion cylinder 21. The resultant gases may drive a turbine or be used for jet propulsion.
