Abstract: 919,889. Supply systems for discharge lamps. ASSOCIATED ELECTRIC INDUSTRIES Ltd. March 16, 1961 [March 16, 1960], No. 9322/60. Class 38 (4). A ballast resistor for use in ah electric lighting circuit arrangement comprising one or more discharge lamps and a control gear housing, is formed by a resistance wire insulated with a heat resisting material and which is embodied in cabling carrying the lamp supply current. Cabling 3 used to connect fluorescent tube heaters 2 to a control gear housing 4 containing the usual tube starting apparatus embodies a ballast resistor 7 formed from resistance wire wound on a heat-resisting core of insulating material such as asbestos or glass fibre and which is similarly sheathed. The right-hand section of cabling shown includes an insulated stranded copper conductor 8 together with the resistance wire in a common sheath. Starting of the fluorescent tube 1 may be facilitated by the use of metallic strip 9 forming an artificial earth and connected to the mains supply S within the housing through a high resistor 10 and a capacitor 11. Specification 919,890 is referred to.

Title: Improvements in or relating to metal pit props
IPC: E21D15/502
Filed: 1955-03-31
Abstract: 768,759. Pit props. GUTEHOFFNUNGSHUTTE STERKRADE AKT.-GES. March 31, 1955 [April 27, 1954], No. 9423/55. Class 20(2) A telescopic pit prop has an inner prop member 1 of channel section within which a laterally acting wedge 7 forces the inner prop member into frictional engagement with a clamp 3 carried by the outer prop member 2, the wedge 7 being supported on one side of the clamp so that vertical frictional forces acting on the wedge when the prop is under load cause the wedge to tilt inwardly to increase the wedging action. The wedge 7 is supported upon the bottom of the clamp 3 by a projection 7a, about which it tilts under load, which projection is engaged by a horizontal cotter 4 by means of which the wedge 7 is tightened in order to set the prop. A spring loaded pin 9 lifts the wedge 7 when it has been released to recover the prop.

[Class 8 (i)] [Also in Group XXVI] A free-piston compressor comprises a prime mover cylinder 1, Fig. 1, a gas compressor cylinder 2, a plurality of free - pistons assembled in two movable systems consisting of pistons 3. 5, 7 and 4, 6, 8, the pistons of each system being rigidly connected together and means, e.g. valved ports 16, 17, 16<1>, 17<1>, whereby gaseous working fluid is introduced between adjacent pistons 3, 4 or 4, 5 of the prime mover cylinder together with means, e.g. valved inlet and outlet ports 14, 15 and 14<1>, 15<1>, whereby gas to be compressed is confined between adjacent mutually approaching compressor pistons 6, 7 or 7, 8. The prime mover is actuated by steam or gas under pressure entering one or other of the intake ports 16, 17 which together with the exhaust ports 16<1>, 17<1> and corresponding compressor ports 14, 15, 14<1> and 15<1> are symmetrically situated with respect to the appropriate pistons. The two groups of pistons connected together by pairs of rods 9-11 and 13, 19, Fig. 2, and urged by balanced forces as described in Specification 580,161 are suspended in a known way through a system of equalizers (not shown) on a suspension shaft 18. In a modification wherein the two cylinders are coaxial and of equal cross-sectional area, the cylinders may be integral as may the prime mover piston 5 and the compressor piston 6 ; the suspension shaft being arranged at the upper end of the common cylinder. The valves controlling the inlet and exhaust ports of the prime mover and the compressor may comprise an articulated system actuated by the rotation of a shaft 39, Fig. 4, which derives continuous rotary motion from two rocking shafts 37, 38 synchronized by a connecting rod 38<1> and actuated by the two movable systems through links 33, 34 and levers 35, 36, 41. To overcome inequalities in amplitudes of the rocking shafts 37, 38, the latter may be provided with a spur-wheel meshing with a pinion which, by means of a crank, actuates the shaft 39 through the rod 41 and crank 40 ; the ratio of the gearing is so chosen that the former crank oscillates through an arc at about 180 degrees. In a modification, the shaft 39 may be connected by a friction coupling and a flexible coupling to a further shaft, the more uniform rotation of which serves to actuate the valve system.
