Title: Improvements in or relating to methods of making joints between metallic and non-metallic parts
IPC: C04B37/02
Filed: 1957-04-05
Abstract: A ceramic or other non-metallic member is soldered to a metal member by means of an activated solder after first metallizing a predetermined area of the non-metallc member, the activated solder being applied over the metallized area only.  An activated solder is defined as one which is capable of wetting the non-metal without employing any other materials and suitable solders include titanium or zirconium alloyed with silver, copper or a eutectic mixture of these; titanium-lead alloys; or titanium or zirconium compounds with indium or nickel.  The solder may behave as a normal solder below a certain temperature and as an activated solder above it, e.g. one having a composition by weight of approximately 85-90 per cent of a eutectic silver and copper mixture, 5-10 per cent indium and 5 per cent titanium.  The metallization may be effected by spraying, brushing or electrodeposition and may be anchored by sintering or stoving e.g. a paste of molybdenum, tungsten or iron powder may be brushed on and then sintered or stoved at 1000 DEG C. to 1200 DEG C. The metallic layer must be thin enough to allow the solder to penetrate to the non-metallic surface.  The non-metallic member may be hard or soft glass or quartz.

Abstract: A triorganostannoxy-alkoxy aryloxy aralkoxy or alkaryloxy aluminium is reacted with water, a carboxylic acid anhydride, a triorganostannoxy diacyloxy aluminium, or a diorgano diacyloxy tin. ("Acyloxy" in this context means RCOO where R is organo, and "Organo" in this context means alkyl, aryl, aralkyl or alkaryl).  The reactions may be represented thus: <FORM:0929246/IV(a)/1> C3H7 being a preferred substituent.  Catalysts, e.g. alkali metal alcoholates or other ester-interchange catalysts or elevated temperatures with or without high pressures may be p  employed.  Trialkoxy aluminum may be added to cause cross-linking of the polymers.  The polymers contain reactive end-groups which react with other polymers, e.g. alkyds, and reactive groups in polymers, e.g. phenolic hydroxy groups, ester groups by interchange, amine groups, epoxy groups, silicone hydroxyl groups, and with drying oil fatty acids.  Fillers may be added, and the polymers may be cured with a variety of catalysts (metal carboxylates and oxides, organic peroxides, quaternary ammonium salts &c.).ALSO:Triorgano stannoxy-alkoxy, aryloxy, aralkoxy or alkaryloxy aluminium compounds are produced by the reaction: <FORM:0929246/IV(a)/1> where n is 1, 2 or 3, and R and R1 are alkyl, aryl, aralkyl or alkaryl groups.  They are then reacted with water, (RCO)2O, triorganostannoxy diacyloxy aluminium, or diorgano diacyloxy tin to give polymers, which may be oligomers.  In the examples: <FORM:0929246/IV(a)/2> <FORM:0929246/IV(a)/3> <FORM:0929246/IV(a)/4> and (8) (C4H9)3SnOAl(OC3H7)2  are prepared.  The catalyst may be an ester-interchange catalyst, e.g. alkaline metal alcoholate.  Other possible means of preparing the compounds are mentioned.

Title: Power clutch assemblage
IPC: B60K17/02
Filed: 1939-04-13
Abstract: 527,719. Fluid-pressure servomotor-control systems ; controlling motor-vehicles. STONE, A. R. April 13, 1939, No. 11204. [Class 135] [Also in Group XXXI] An engine-suction servomotor 11, Fig. 1, operating the clutch pedal 20 of a motor-vehicle, is controlled by a tubular piston valve 27, Fig. 2, which is actuated by an electromagnet 30 energized by the engine generator 8. At low speeds, the generator being cut-out or the current being small, the valve 27 occupies the position shown, under the action of a tension spring 34, in which ports 29 in the valve register with ports 24 connected to the engine intake manifold. Suction is thus applied to the servo 11 to disengage the clutch, and the servo suction then acts on the valve 27 to assist the spring 34 in maintaining this position of the valve. At increased speeds, the magnet operates to move the valve to the left until ports 28 in the valve register with atmospheric ports 23 so as to cause engagement of the clutch, such movement of the valve being resisted by the spring 34, and, initially, by the servo suction acting on the valve. Gradual engagement of the clutch is thus obtained. An adjustable shunt 37 is connected across the magnet coil, and a short-circuiting switch 39, also connected across the coil, is mounted on the gear lever 41. During gear changes, the switch 39 is closed so as to de-energize the magnet and effect clutch disengagement. The brakes are simultaneously operated by a power cylinder 15 connected to the engine induction pipe by pipes 18, 19<SP>1</SP> and a control valve 19. This valve, Fig. 4, comprises a tubular member 57 closed at one end and provided with peripheral ports 63 adapted to co-operate with ports 53 leading to atmosphere. When a control rod 62 is moved to tension a spring connection 61 a rod 60 moves the valve against the action of a light spring 64 to connect a port 52 leading to the power cylinder with ports 54 leading to an annular chamber connected by a pipe 56 with the induction pipe of the engine. As the suction increases in the power cylinder the control valve is automatically moved back to its neutral position. A handle 73 situated adjacent the steering wheel 71 is slidably mounted on the steering column and carries a slip-ring 74 adapted to reciprocate a rod 78 slidably guided in a fixed lug 77. The rod 78 carries a socket 79 having a lost motion connection with the linkage 7 for actuating the engine throttle 6 and also carries a lug 81 having a lost-motion connection with the rod 62. As the handle is moved towards the steering wheel the throttle is first moved to the slow-running position and is followed by a graduated application of the brakes.

Abstract: 1299632 Fuel injection systems SOC DES PROCEDES MODERNES D'INJECTION SOPROMI 10 March 1970 [10 March 1969] 11531/70 Heading G1N [Also in Division H3] In an I.C. engine intermittant fuel injection control system, the initiation of injection is delayed with respect to a predetermined position of rotation of the engine, which delay is dependent upon the engine speed and other operating parameters of the engine, i.e. the load. Rotation of the engine provides pulses A, each pulse causing initiation of a sawtooth voltage from a generator B. When the sawtooth voltage reaches a pre-set peak, (i.e. when a capacitor 3 has charged to a pre-set value), a pulse T<SP>1</SP>o is applied, from a circuit C, to a pair of monostable multi-vibrators D, E, D producing fixed duration pulses T 1  and E producing pulses having a duration T 2  depending on engine parameters (determined by resistance 38). The outputs of the multi-vibrators p are applied to a circuit F which produces output pulses of duration T = T 1  - T 2  for initiating injection. Hence, initiation of injection is delayed with respect to initiation of each pulse A by a period T 0  + T 2 , T 0  depending on the engine speed and T 2  depending on engine load conditions, injection being initiated by the end of the pulse T 2  and being terminated by the end of the pulse T 1 .
