Title: Process for the preparation of 1h-tetrazole-5-thiol derivatives
IPC: C07B61/00
Filed: 1974-10-30
Abstract: Compounds of the formula: <IMAGE> in which R1 is alkyl, cycloalkyl, acylaminoalkyl, unsubstituted aryl, alkyl-, halogen- or alkylamino-substituted aryl are prepared by aralkylation of a thiosemicarbazide R1NHCSNHNH2 to form an 4-(R1)-3-aralkylthiosemicarbazide, diazotization with ring closure and formation of a 5-aralkylthio-1H-tetrazole and treatment of the latter with a Friedel-Crafts catalyst. The acylaminoalkyl compounds can be hydrolysed to the aminoalkyl compounds and the latter can be converted into N-alkoxycarbonyl derivatives; the aminoalkyl, acylaminoalkyl and alkoxycarbonylaminoalkyl compounds are novel. The compounds are suitable as intermediates for the preparation of cephalosporin derivatives.

Title: Improvements in the method of and means for controlling aeroplanes
IPC: B64C9/28
Filed: 1923-07-16
Abstract: 223,292. Page, r. H., and Page, Ltd., H. July 16, 1923. Balancing.-In an aeroplane of the type in which a transverse slot is provided in each wing to increase the lift by reducing burbling when flying at large angles of incidence, the lateral balancing effect produced by operation of the ailerons is increased by providing a connection from each aileron to means for disturbing the flow of air adjacent to or through the slot in the corresponding wing so that such means become effective to reduce the lift on the higher side of the machine when the ailerons are operated. In one arrangement, Fig. 3, the slot between the main wing 1 and a pivoted auxiliary wing 2 is closed against the action of a spring 2<a >upon upward movement of the aileron 3 from its normal position to the position shown, a lost motion connection being provided between the aileron and' the connecting rod 4 to prevent any operation of the wing 2 upon downward movement of the aileron from its normal position. Independent control mechanism, not shown, is provided for closing the slots in the two wings simultaneously. In a modified arrangement, Fig. 6, upward movement of the aileron to the position shown raises the wing 2 against the action of a spring 2<a> into position to disturb the air flow above the slot. The slots in the two wings may be closed simultaneously by the springs 2<a> by simultaneous lowering of stops 2<c>, and, to enable the ailerons to be moved freely when the slots are thus closed, each rod 4 may be lengthened by operating the pulley 4<b> of a right and left-handed screw adjustment 4<a>. In the arrangement shown in Fig. 7, the rod 4 is pivoted to the aileron 3 and to the wing 2, and the points of connection of the rod are so arranged in relation to the pivotal axes of the aileron and the wing that much greater movements are imparted to the wing during the movements of the aileron above the normal position, than during its movements below the normal position. In this case the wings 2 are operated to open or close the two slots simultaneously by operating simultaneously the pulleys 4<b> to lengthen or shorten the two rods 4. The flow of air through or adjacent to the slots may be disturbed by flaps pivoted to the auxiliary wings 2 or to the main wings 1 about transverse horizontal axes, e.g. as shown at 8, Fig. 11, or about longitudinal horizontal axes as shown at 11, Figs. 15 and 16, or about vertical axes as shown in plan at 13, Fig. 18. Fig. 22 shows an arrangement for operating a flap 9 from the aileron 3 without a lost motion connection, the lower movements of the flap being within a recess in the main wing 1. Specifications 157,567, 172,109, and 176,909 are referred' to.

Filed: 1916-12-21
Abstract: 127.004. Soc. Anon. pour l'Exploitation des ProcÚdÚs Westinghouse-Leblanc. Jan. 25, 1916, [Convention date]. Stuffing-boxes, substitutes for.-In a fuel pump for an internalcombustion engine, the plunger 1 passes through two stuffing-boxes, between which is a space 6 connected to the engine cylinder by a duct 7, so that during the delivery stroke fuel is prevented from escaping through the lower stuffing-box by the high air pressure in the space 4 in the gland 3. The space 4 is connected to the space 6 by ports 5 in the gland. The upper stuffing-box prevents the escape of air from the spaces 4, 6 and consists of the upper enlarged portion of the gland 3 provided with an internal packing 8 and gland 9 and an external packing 11 and gland 12. In the modification shown in Figs. 2, the upper stuffing- box is replaced by the upper part of the gland 3 provided with grooves 14 which reduce leakage of air along the plunger. Leakage of air along the outside of the gland escapes into a chamber 15, which is nearly sealed by the nut 16 which presses the gland against its packing.

Abstract: 791,268. Generating combustion products under pressure. GENERAL MOTORS CORPORATION. June 14, 1956, No. 18400/56. Class 51 (1). [Also in Groups XXVI and XXVIII] To start a gas-turbine engine comprising a combustion system connected to a compressor outlet, the engine is provided with an injector for injecting fuel into a part of the combustion system during starting only of the engine and a one-way valve operable automatically during starting only to shut off this part of the combustion system from the compressor outlet. A number of combustion chambers 12, Fig. 1, each consisting of a cylindrical outer casing 22 and a flame tube 24, are arranged around the engine axis. The outer casings 22 are attached by ring clamps 28 to flanges 30 provided around openings in an end plate or bulkhead 32 arranged at the end of the compressor diffuser 14. Fuel injectors 36 supported by mounting pads 38 from the wall of the diffuser 14 project into dome-shaped members 34 forming the inlet ends of the flame tubes. Interconnector pipes 46, Fig. 3, provided between adjacent combustion chambers, comprise a pair of outer tubes 47, 48 and a pair of inner tubes 50, 51. These tubes are provided with flanges 54, 55, 58, 59 which are welded over openings formed in the surface of the outer casings 22 and flame tubes 24, respectively. For starting purposes, one of the combustion chambers, is provided with a one-way valve 62 and a second fuel injector 82 by means of which fuel and an oxidant, such as liquid oxygen, is introduced into the combustion chamber. The valve 62 is formed by inner and outer rings 66, 64 in which are pivoted a number of rods 70 carrying radial flaps 68. The flaps 68 are formed as truncated sector-shaped plates and are welded at one side to the rods 70. The inner ring 66 is polygonal in cross-section and surrounds the nozzle 42 of the fuel injector 36 to which it is attached by a bayonet clip 74. The interconnector pipes 46 adjacent the starting combustion chamber are provided with valves 94, Fig. 3, which are actuated by levers from a rotating electric solenoid. To start the engine, a circuit comprising this solenoid, an igniter 92 and electrical control valves controlling the supply of fuel and oxidant to the fuel injector is energized through a time switch. This causes the valves 94 to close and the fuel from the injector 82 to be ignited. The resulting pressure in the combustion chamber causes the valve 62 to close. The combustion products contain sufficient energy to enable the engine to reach its normal firing speed of 1,500 to 2,500 r.p.m. in 6 to 10 seconds. The time switch then de-energizes the circuit, which causes the valves 94 to open, the igniter 92 to be deenergized and the fuel and oxidant supplies to the fuel injector 82 to be cut off. The flow of air from the compressor is then sufficient to open the valve 62. The main ignition and fuel supply system is set into operation before the end of the starting period and takes over control of the engine at the end of this period.

Heading G3P [Also in Division F1] A control system for actuating the control members of a double regulation hydraulic turbine, such as Kaplan or Pelton turbine comprises servomotors 10a, 10b connected to the control members, such as a deflector 12a and blades 12b, the pistons 42, 43 of the servomotor being connected by linkage 63, 33, 64. Each servomotor has a control valve 40, 41 connected by linkage to a lever 30 and to a cam follower 16. The lever 30 is actuated by a speed input 1 to move the controls in the same direction, as indicated by arrows 44, 45. The linkage 33 carries a cam 15 which normally provides the feedback in response to movement of the servomotors from the input signal. If, however one control is too open, the linkage acts to move the servomotors in opposite directions to correct the error. Assume for example that the piston 43 is too far to the right, the link 33 will rotate anticlockwise about pivot 14a causing anticlockwise movement of the cam 15 which allows follower 16 to move downwards. The linkage thus lowers valve 40 to move 42 to the right and lifts valve 41 to move piston 43 to the left until the valves are recentred.
