Abstract: 1,029,156. Spring drums. RALEIGH INDUSTRIES Ltd. June 1, 1964 [March 30, 1963], No. 12702/63. Heading B8B. [Also in Division A3] A spring reel for a safety harness comprises an inertia mass acting upon a piston member slidable axially of the reel against spring pressure to effect locking means for the reel at a predetermined acceleration of the vehicle. The strap 22 is wound on a reel 11 rotatable on a sleeve 16a integral with a piston housing 16 and having a retracting spring 12 at each end. The inertia mass 14 lies on interdigitated fingers 13d of two piston members 13a slidable within the sleeve 16a The members are urged together by springs 19 lying in a recess at each end of the piston and contacting the housing 16. Movement of the inertia mass 14 at a predetermined acceleration moves a piston member and displaces balls 15a from a channel in the piston member into recesses in a reel flange 11a locking the reel against movement. The piston members may be rotated by a key 20 to bring the fingers or the like beneath the mass 14. A single piston member may be provided with a linkage operating on opposite ends of the reel and the interdigitated fingers may be replaced by overlapping shelves or platforms.

Abstract: 1487827 Indexable tool turrets ROLLS-ROYCE Ltd 14 March 1975 [22 March 1974] 12852/74 Headings B3T and B3B A machine tool turret assembly comprises an indexable base member 28 to which cutting tools may be secured, a pair of coaxial sleeve members 64, 66 of electrically non-conductive  material surmounting the base and located coaxially one within the other for relative movement with respect to their common axis P which is normal to the base member 28, one of the sleeves having connections and passages for the flow of water gas, and electricity and the other sleeve having means which co-operate with the passages in the first sleeve in each indexed position of the turret for directing the flows from the first sleeve to a cutting tool and plasma torch unit in the operative indexed position of the turret. In the embodiment described a central shaft 42 is threadably engaged with the base support 22, the shaft 42 supporting the base member 28 by way of a flange 48 and flanged sleeves 54 and 62, rotation between these sleeves being prevented by a screw 68 but axial displacement is permitted. The sleeves 66 and 64 of electrically non- conductive material are respectively secured to the turret base 28 by bolts and to the inner sleeve 62 by pin 72, so as to be relatively displaceable with respect to each other both axially and rotationally as the shaft 42 is rotated by the handle 74 attached to the boss 50. A loom of tubes 94 is connectable to the flange of the sleeve 64 for the supply of water, air argon, the flows of which are conducted through passages, for example 98, 100, in the sleeve 64 and which contains conduits which co-operate with ports in the sleeve 66 at the respective indexed positions of the turret to supply water, air and/ or argon to a cutting tool and plasma torch 82, 88 ; 84, 90; 86, 92 at the respective tool positions. The electrical supply to the plasma torches is effected conduction through the water supply pipes and passages and is achieved in the turret assembly by metal interconnecting contact strips between the inlet and outlet ports of water supply connections. The electrical supply is connected through the workpiece to complete the circuit for heating the workpiece by the torch during machining.

Title: Improvements in or relating to power supply arrangements for variable loads
IPC: H02M1/14
Filed: 1938-05-03
Abstract: 514,334. Converting; supply systems for cathode-ray tubes. FAUDELL, C. L. May 3, 1938, No. 13171. [Classes 38 (ii) and 38 (iv)] In an arrangement including series inductance and shunt capacity smoothing means, for supplying rectified A.C. to a load, a substantial part of which can be switched in or out of circuit, a part of the shunt capacity is rendered ineffective when the load is switched out of circuit. In the application to a combined sound and television receiver including means for switching off unused vision stages where only sound signals are being received, the A.C. source 2 supplies transformers 3 for the heaters of the valves used for television and for the energization of the cathode ray tube, while transformer 4 supplies A.C. to the heaters of the sound valves and to a rectifier 6 for supplying H.T. current to all the valves. The H.T. current is smoothed by inductances 13, 14, 15 and condensers 8-12 before it is led to sound and television rectification leads 16 and 17. When transformer 3 is cut out by switch 20, condenser 3 is simultaneously rendered ineffective by the opening of switch 18. A high resistance 19 in series with condenser 8 maintains a static charge on the condenser when switch 18 is open so that there is no appreciable sudden charging action when the switch is closed.

Abstract: <PICT:0475056/III/1> In the de-greasing of metal articles with a volatile solvent, in which the articles are first treated with cold solvent and then with hot solvent or solvent vapour, the used cold solvent passes through a filter before admission to the heated solvent zone, whereby finely divided metal and other suspended materials are removed.  The filter may consist of a removable gauze screen mounted above a partition in a tank through which the solvent passes from one section to the next, or a separate filter may be used.  In the form shown a tank 1 is provided with a double-walled partition 2, acting as a heat insulator, to form a cold solvent compartment 3 and a solvent vapour compartment 4.  A heater 7 is mounted below a perforated work support 5 and the solvent vapours condense on cooling coils 8 and pass from a gutter 9 to the compartment 3, where the solvent is maintained cold by a cooling coil 6.  The compartments 3 and 4 are supplied with a solvent such as trichlorethylene through a pipe 20, hand pump 11, and pipes 21, 22, a filter 17 and a pipe 19.  The distillate from compartment 4 passes to compartment 3 displacing solvent which passes through a pipe 24 and filter 17 to the heated solvent compartment 4.  The metal articles are first immersed in cold solvent, raising them to drain and finally treating with solvent vapour in compartment 4.  At intervals the whole solvent is purified by filtering into chamber 4, and distilling into chamber 3.  Specification 433,472 is referred to.
