Abstract: 970,408. Vehicle suspensions. BOFORS A.B. Nov. 24, 1961 [Nov. 26, 1960], No. 42137/61. Heading B7D. In a tractor suspension which maintains the vehicle at a predetermined altitude to the mean ground surface by raising one wheel or a diagonally opposite pair when the other wheel encounters a protruberance in the ground surface and simultaneously lowering the other diagonal pair, electrohydraulic systems 27, 28, 29 pump fluid to hydraulic cylinders 25fv, 25fh &c. to control the altitude of pivoted arms 6, 11, 22, 24 carrying the vehicle wheels 4, 11, 21, 24, and by means of resolvers 26fv, 26fh &c. coupled to the pivoted arms voltages proportional to the displacement of each wheel are transmitted to the electrohydraulic systems 27, 28, 29 which compare the voltages and raise or lower each wheel accordingly. By means of an aiming gear resolver 30 the angle of the vehicle's longitudinal axis relative to the ground can be adjusted and a control member 32 sets the height of the vehicle above mean ground level. The system may also function to maintain constant tension in endless tracks running over the wheels on each side of the vehicle.

Title: Bladed Rotor for a Fluid Flow Machine

Abstract: 1,173,834. Making bladed rotors; welding by fusion; brazing. ROLLS-ROYCE Ltd. 17 Nov., 1967 [29 Nov., 1966], No. 42876/67. Divided out of 1,170,592. Headings B3A and B3R. [Also in Divisions B5 and F1] Blades are bonded to the rotor of a fluidflow machine, e.g. a gas-turbine engine, by means comprising fibrous material. The fibrous material may be synthetic resin reinforced with carboniferous or boron fibres or alternatively the fibres may be coated with a metal, e.g. beryllium, cobalt, nickel, hafnium, niobium, osmium, palladium, platinum, rhenium, rhodium, tantalum or vanadium, or a nickelchromium alloy. In a compressor application for a gas-turbine engine, fibre-reinforced synthetic resin blades 10 are secured to a rotor 11 by fibre-reinforced synthetic resin tapes 16 passing over the blade roots 12. The tapes 16 are bonded to both the side walls 13, 14 of the rotor and to the roots 12 when the complete assembly is cured in a mould so that, in operation, at least some of the centrifugal loads to which the blades 10 are subjected are transmitted to the rotor 11 by the tapes 16 in shear. The blades 10 may also be bonded to the rotor 11 and are hollow to receive cooling air from the rotor interior. Instead of using tapes 16, the roots 12 may be bound to the rotor by fibres which are subsequently embedded in synthetic resin material. In a modification, Fig. 3 (not shown), the tapes or fibres (23) do not pass over the blade roots (21) but are bonded to flat or curved axially facing end surfaces (22) of the roots. The tapes (23) are bonded to each other where they overlap. The rotor 11 may be reinforced by circumferentially extending fibres. When metal coated fibres are used the coating may be applied by electrolytic plating, spraying or vacuum deposition, and the bonding effected by plating, brazing, electron beam-welding or spraying.

Abstract: 956,146. Fibre feeding apparatus. COTTON, SILK & MAN-MADE FIBRES RESEARCH ASSOCIATION. March 16,1961 [Dec. 17,1959], No. 42930/59. Heading D1N. [Also in Division G3] In a scutcher or like machine in which a fibrous web of variable thickness longitudinally and laterally is subjected to treatment that modifies its weight per unit length and in which the web is passed between a roller and a series of detectors disposed axially of the roller to initiate compensating adjustments to the machine to preserve an even feed of material, a reaction member is interposed in such manner that the roller and reaction member are urged towards each other. The loading of the detectors is preferably by helical springs with a stiffness so chosen that the relationship between weight per unit length and the thickness of the material will be substantially linear over a given working range. Matching springs may be used to urge together the roller and reaction member. Detectors B are pressed against a fibrous web passing beneath a roller A by springs S1 carried by the reaction member C that may be a sliding or a pivoted plate urged towards the roller A by matching springs S2. Drive to the roller A may be by a variable speed motor I controlled by an open loop system comprising a transducer F influenced by member C, a function generator G and an amplifier H. In another embodiment, the signal from the amplifier controls a servomotor that by mechanical means removes excess material from the web. A further embodiment has a motor operating an excess material remover switched on when the web deviates from a desired thickness. Other forms of detectors than those shown may be used, e.g. the detectors may be in the form of leaf springs and the helical springs be dispensed with. According to the Provisional Specification instead of pivoted detectors, detectors journalled in holes in the reaction member and provided with coaxial springs may be used.

Abstract: 1,113,958. Transistor switching circuits. ROBERT BOSCH G.m.b.H. 11 Oct., 1965 [9 Oct., 1964; 25 March, 1965], No. 43027/65. Heading H3T. [Also in Division G4] A flashing light signalling circuit comprising at least two parallel connected lamps in series with a contact-breaker is monitored by a transistor switching circuit including a pilot lamp, the control electrode of the transistor being connected to a resistor in series with the contact-breaker and the signalling lamps. As described the circuit is applied to a vehicle turn indicator system. In one embodiment, Fig. 4, parallel connected signalling lamps 50, 51, 52 are in series with a flasher contact 11 and a resistor 12. With all three signalling lamps functioning correctly the transistors 56, 57, 58 connected to resistor 12 switch on and off to flash pilot lamps 53, 54; 55, transistor 43 providing a feedback circuit which is temperature compensated by means of a temperature variable resistor 45. The three transistors 56, 57, 58 are biased to be switched by different control potentials, so that in the event of failure of one lamp 50, 51, 52 the reduced potential across resistor 12 is insufficient to switch one of the transistors 56, 57, 58 and its associated lamp remains unlit. Failure of two lamps further reduces the potential across resistor 12 and two transistors remain cut-off. Failure of all three lamps results in all transistors being cut-off, and all monitor lamps 53, 54, 55 are unlit. In order to delay operation of the circuit until the lamps 50, 51, 52 attain their normal working resistance a capacitor 66 is included in the circuit which charges up when the contact 11 is open. When contact 11 closes, the potential on this capacitor hold all transistors cut-off until it discharges, by which time the lamps 50, 51, 52 have attained their normal working resistance. Various modifications are described in which: the feedback transistor is omitted, Fig. 2 (not shown); only one indicator circuit is provided, Figs. 1, 3 (not shown); the transistors are connected in common base instead of common emitter circuit, Figs. 5, 6, 7 (not shown). In the circuit of Fig. 6 (not shown), each switching circuit comprises two transistors, and in that of Fig. 7 (not shown), NPN transistors are used. In further modifications, Figs. 8, 10 (not shown), the feedback circuit is omitted and the signal is fed to the switching transistors via an amplifier stage (104). In these two arrangements the resistor (102) is arranged to be temperature variable to compensate for variation in the lamp resistances with temperature.

The tone-sounder described in Specification 985,198 which comprises a transistor oscillator VT2 arranged to operate an electro-acoustic transducer under the control of an incoming low audio-frequency signal is modified for use on party lines where each party is allotted a different control frequency by the provision of a switching transistor VT1 with a tuned circuit T2P, C3. If the control signal has a frequency substantially equal to that of the tuned circuit, VT1 will conduct heavily during alternate halfcycles and drive the oscillator VT2 into oscillation at the frequency of its tuned circuit T3P, C4, TD, thus causing the transducer TD to emit an audible tone. The driving power is derived from capacitor C2 which charges during the half-cycles when VT1 is non-conductive. Resistor R4 provides negative feedback to reduce any tendency for VT2 to self-oscillate when not driven. If three tone-sounders are connected to the same party line they may be arranged to respond to control signals having frequencies of 300, 400 and 500 c/s. The frequency of the oscillator VT2 may, however, be the same for all of them.
