Abstract: 696,142. Actuation of switches. GENERAL ELECTRIC CO., Ltd., and TAYLOR, S. Nov. 9, 1951 [Nov. 9, 1950], No. 27421/50. Class 38 (v) [Also in Group XXXII] In a circuit breaker a composite torsion spring comprising an outer tubular member and an inner rod is used to assist in opening the circuitbreaker contacts. The Figures show an arrangement in which two composite springs are used, each spring comprising an outer torsion tube 11 splined at one end into an adjustablyfixed supporting member 10 and an inner torsion rod 18 splined at one end into the other end of the tube 11 and at its other end into a lever assembly 2. The lever assembly 2 has bosses 16 rotatably supported in the members 10, the bosses 16 providing bearings for main contact lifting levers 3 interconnected by a pin 23 to which a pull rod 24 is connected. The lever assembly 2 has arms 25 which can contact the pin 23 and a U-shaped part 27 having an adjusting bolt 29 which abuts a stop member 28 to limit the movement of the lever 2. To close the circuit-breaker, the rod 24 is raised and during the last part of its travel, the pin 23 engages the arms 25 and moves them into the chain-line position of Fig. 2 to stress the torsion springs 11, 18. When the circuitbreaker is opened, the arms 25 move down with pin 23 and levers 3 until the bolt 29 engages the stop 28, the force derived from the springs assisting in accelerating the moving contact or contacts (not shown). Each member 10 is rotatably retained in an aperture in a frame by a clamping member 13 to which it is bolted and has a depending lug 12 engaged by bolts 30, which may be adjusted to rotate the member 10 to vary the loading of the associated torsion spring. The Provisional Specification describes an arrangement having one composite torsion spring.

Title: Improvements in combustion ducts
Inventor: SARGENT RAYMOND FREDERICK
IPC: F23R3/00
Filed: 1957-08-30
Abstract: 872,600. Generating combustion products under pressure. BRISTOL SIDDELEY ENGINES Ltd. Sept. 1, 1958 [Aug. 30, 1957], No. 27469/57. Class 51 (1). [Also in Group XXVI] In combustion equipment comprising a duct through which can flow a fast-moving stream of gaseous combustion-supporting fluid, a baffle member is supported within the duct so as to define a pilot combustion zone having at least one intake opening for inflow of fluid from the duct, a body being mounted within the duct upstream of the intake of the pilot combustion zone, and means being provided for diverting wake from the body away from the intake. The invention is shown applied in the case of a ram-jet engine which comprises a duct 3 which is of double-walled construction where indicated at 4, 5, the two walls being spaced apart by means of strengthening rings 6, 7. A central body 9 is disposed within the duct 3 for the purpose of obtaining multi-shock compression, only the downstream end of the body being shown. A baffle member in the form of a perforated flame tube 10 is disposed centrally within the duct 3 downstream of the central body 9, the flame tube having an intake 12 provided with a ring of swirl-producing vanes and defining a pilot combustion zone 11. Liquid fuel is supplied to the zone 11 through a sprayer 13, fuel flowing to the injector through pipe 14 from a ring manifold 15 disposed around the flame tube. The manifold 15 also supplies a number of primary sprayers 16, for example, six. Primary combustion air enters the flame tube through a row of holes 18 and assists in the formation of a toroidal vortex in the pilot combustion zone, while secondary air enters through the row of holes 19 downstream of the pilot combustion zone. Air mixed with fuel from the primary sprayers 16 enters the flame tube through further rows of inlet openings 20, 21. A second fuel manifold 22 supplying secondary sprayers 23 is disposed downstream of the first manifold 15, air mixed with fuel from the secondary sprayers entering the flame tube through further inlet openings, not shown. The central body 9 is supported within the duct 3 by means of three vanes 25, the downstream ends 26 of the vanes being of rounded U-shape section, and diverging outwardly at such an angle that the boundary layer is not liable to break away from the vanes before a sufficient distance from the axis of the duct is reached. The fuel supplied to the pilot and primary sprayers maintains a constant air/ fuel ratio while the separate supply to the secondary sprayers is controlled to vary the thrust of the engine. The invention is also applicable to reheat equipment of a gas turbine jet engine.

Title: Improvements in pneumatic player actions for player pianos
Filed: 1923-11-01
Abstract: 228,268. Brown, T. P. Nov. 1, 1923. Exhausting air; winding-mechanism.-To prevent fluttering of the valves of the action, an automatic valve-device controlled by the movement of the collapsable suction-reservoir is inserted between the reservoir and the action and acts to cut off the suction from the action until it has increased sufficiently to seat all the valves simultaneously. The valve-device consists of a diaphragm 11 arranged in a box 7 which is connected by tubes 12, 15 to an atmosphere valve 18, by a tube 6 to the action, and by a tube 5 to the suction reservoir 4. On commencing pedalling the reservoir 4 at first holds the valve 18 open thereby permitting the diaphragm 11 to rise and close the end of the tube 6. The action is thus cut off from the suction until the reservoir 4 has collapsed sufficiently to allow the valve 18 to be closed by its spring 19, when the diaphragm 11 falls. Movement of the lever 49 to the re-wind position shown in dotted lines, opens the tube 12 to atmosphere at 51, thereby cutting off the action from suction during re-winding.

Abstract: 518,450. Alkyl phenols. GROVES, W. W. (Monsato Chemical Co.). Sept. 29, 1938, No. 28345. [Class 2 (iii)] Alkyl phenols of the benzene series are manufactured by subjecting the sodium salt of -the aromatic sulphonic acid corresponding with the desired phenol to fusion with sodium hydroxide in the presence of the sodium salt of another aromatic sulphonic acid or the sodium salt of a phenol. In examples (1) 2.4 molecular proportions of sodium hydroxide and 1 molecular proportion of a mixture of sodium benzene sulphonate and sodium p-toluene (equimolecular proportions) are fused together at 300-350‹ C. giving a mixture of phenol and p-cresol. (2) As in (1) but the sulphonates are used in the proportions, 1 of sodium benzene sulphonate to 4 of sodium p-toluene sulphonate. (3) as in (1) but replacing the sodium benzene sulphonate by the sodium salt of phenol or (in (4)) by the sodium salt of p-cresol. Instead of the sodium benzene sulphonate there may also be used the sodium salts of other aromatic sulphonic acids and phenols, including the sodium salts of isopropylphenol, p-tertiaryamylphenol and other cresols. An alternative method of working is to fuse together sodium benzene sulphonate and sodium hydroxide, then add sodium p-toluene sulphonate and fuse further to give the p-cresol. Or sodium hydroxide is added to a residue of sodium phenate resulting from a phenol fusion. After melting this mass, sodium p-toluenesulphohate is added and the fusion continued until the toluenesulphonate is converted to p-cresol.
