Abstract: Silicon boride of general formula SiBx, where x=2.5 to p  14, is produced either by hot-pressing a mixture of Si and B powders in a graphite mould at 1700 DEG  C. or by a thermo aluminic reaction between boron, silicon, boric acid and/or SiO2 with Mg powder or Al powder in a hydrogen atmosphere.  The reaction product is crushed and leached with 10% HCl to remove excess Al or Mg.  The SiBx is used to form a sintered composition consisting of 20-98% SiBx and 2 to 80% of a binder containing Si and/or B (see Group II).  Specification 791,324 is referred to.ALSO:A sintered composition consists of by weight 20%-98% silicon bromide of general formula Sibx, where X = 2.5 to 14, or 2%-80% of a binder containing Si/or B.  The binder preferably contains 10% to 80% of B plus Si which may be bound to one or more of the following Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, e.g. as MSi2 or M5Si3 and C, N or O, e.g. as SiC, Si3N4 and SiO2.  A ceramic binder consisting of 60%-100% SiO2, 0%-5%B2O3, 0%-80% Al2O3 or 0%-10% Na2O or K2O may also be used, the liquids temperature of the binder being above 1400 DEG C. The binder may also be added to the powdered SiBx as a powered metal e.g. Al, an alloy powder or an oxide e.g. Al2O3 which react with the SiBx during sintering to form a binder containing Si and B.  The SiBx is mixed with the binder either as the preformed boride or is formed in situ from the constituent powders during the sintering.  The preformed SiBx is produced by hot pressing Si and B at 1600 DEG C. or by a thermo aluminic reaction of a mixture of Si, B2O3 with Al or Mg.  The raw materials finer then 40m  are hall milled together in petrol, a plasticizer e.g. hydrated SiO2 may be added and the mixture then pressed or extruded and preferably presintered in a protective atmosphere and then sintered in oxidizing atmosphere.  Hot pressing may also be used and in one of the examples silicon bromide and boron carbide are mixed with 5% Ni and hot pressed.  Another example specified has a composition of 22% SiB3 and 78% oxide mixture which consists of 15% SiO2, 3% B2O3, 80% Al2O3 and 2% impurities such as Fe2O3 and CaO.

Title: Non-destructive method of investigating a solid capable of being caused to exhibit magnetostrictive properties
IPC: G01N29/04
Filed: 1950-03-27
Abstract: 691,315. Testing physical qualities of materials. McPHAR ENGINEERING CO. OF CANADA, Ltd. March 27, 1950 [April 12, 1949], No. 7633/50. Class 106 (ii). A method of investigating the physical condition of a magnetostrictive solid consists in creating a mechanical wave in the solid and detecting in the travel of such a wave through the solid the characteristics of propogation which arise by virtue of any discontinuity or variation in the physical character of the solid at any point throughout its length, characterized in that the wave is created or detected without physical contact with the solid through the utilization of the magnetostrictive properties of the solid and at a point which may be selected at any distance from the ends thereof. In one form, Fig. 1, a burst of electrical oscillations is sent to a coil 3 surrounding the magnetostrictive body 1 under test. These cause a train of mechanical vibrations in the body accompanied by magnetic variations which are detected by a pick-up coil 4 controlling an oscilloscope 7. The train causes a large deflection 12, Fig. 2, on its outward movement, and a smaller deflection 13 when reflected by a crack 2. In a modification the same coil is used as transmitter and detector. In another form, Figs. 8 and 9, for detecting flaws 21 in flat bodies the transmitting and detection coils 19, 20 are of flat or pancake form. In other modifications the coils may have cores of magnetic materials. The method may be applied to non- magnetostrictive test bodies by first plating or spraying them with magnetostrictive material. The methods described in the Specification are stated to be of particular interest in detecting flaws in mine hoist cables. Specification 661,049, [Group XL (b)], is referred to.

Abstract: 582,991. Fluid measuring devices. LONDEX, Ltd., BESSON, A. P., and DOSSETT, J. V. April 25, 1944, No. 7679. [Class 69 (i)] In a flow indicating device comprising a closing member arranged to be displaced in a fluid passage according to the rate of flow, an indicating member fastened to a spindle carrying the closing member is arranged in a dome of transparent material secured to the hollow body containing the passage. As shown, the closing member comprises a flat disc 1 co-operating with a passage 2 in a dividing web in the casing 3. The disc is carried on a stem 5 guided in a boss 6 and a cover-plate 8 and has at its end an indicating disc 9 working in a transparent dome 10, e.g. of glass clamped with the plate 8 to the casing 3 by a collar nut 11. One side 12 of the dome may be rendered non-transparent, for instance by painting it white to show up the indicating disc 9 which may be coloured. A graduated scale or indicating marks 13 may be provided at one or both sides of the dome. Alternatively, a scale carried by the stem 5 may co-operate with a fixed pointer. The lower part 14 of the dome may be rendered opaque to obscure the disc 9 in the " no flow " position. The closing member 1 may seat on or slide in the passage 2 which may in some cases be tapered to give large displacements of the closing member for small changes in flow. The closing member may be of metal or synthetic moulding-material. It may be rigid or elastic and in the latter case may comprise a disc of rubber, leather or the like supported at one or both sides by smaller rigid discs. The displacement of the closing member may also actuate a relay or like control mechanism, e.g. to start or stop a motor.

Abstract: 781,710. Hardening steel surfaces. MOURAVIEFF, N. March 16, 1955 [March 18, 1954; April 24, 1954; Sept. 15, 1954], No. 7685/55. Class 72 The surface of a piece of steel is hardened by immersing the. piece in a non- inflammable liquid, connecting the piece to one terminal of an electric circuit the other terminal of which is connected to an elongated carbon electrode, supplying current to generate an arc under the surface of the liquid between the electrode and the piece and scanning the electrode over the surface of the piece so that the arc travels over every point of the surface. As shown, a steel plate 1 connected to one terminal of a battery 19 is held on supports 2 in a tank 3 containing water 5. A carbon electrode 4 which may comprise a plurality of electrodes mounted close together and each connected to a secondary winding of a transformer, Fig. 2 (not shown), supported by a leaf spring 15 mounted on a motor driven truck 18 is connected to the other terminal of the battery 19. The truck is then moved so that the electrode, which bears with a slight pressure on the plate 1, travels over the surface of the plate, the heating due to the arc and quenching by the water forming a hardened layer on the plate. In the case of a cylindrical piece, the object may be rotated at the same time as the electrode moves longitudinally giving a helical path to the arc. Specification 476,910 is referred to.

Abstract: 851,460. Ammunition fuzes. VICKERS-ARMSTRONGS (AIRCRAFT) Ltd., CURL, T. I., AMBROSE, M. J. F., and BURCH A. E. Feb. 17, 1959 [March 10, 1958], No. 7690/58. Class 9(1). Contacts 13, 14 of an electric fuze closed on impact are mounted on a probe 12, which may be retracted within the projectile casing 11, during stowage, resilient means 15 being provided to drive the probe to the operative position. In addition releasable locking means are provided to hold the probe in the operative position. Conductors (not shown) connect the contacts 13, 14 to a fuze or igniter in the body 10. A cap (not shown) may be placed over the contacts to protect them during handling and transport. Rotation of the probe is prevented by a pin 18 extending into a longitudinal groove 19. The rear end of the probe has an interrupted flange 17, which bears against a similar flange on a locking collar 21 when the probe is in the operative position. To retract the probe, the collar 21 is rotated by means of a lever 23 until openings in the collar flange are aligned with the flange parts 17. The probe can then be pushed into the projectile, the collar being held in the release position by engagement of a pin 25 with the groove 19 against the force of return spring 22. The projectile may then be stowed in a container which holds the probe retracted. Bolts 214 passing through arcuate slots in the collar allow rotation while preventing axial movement of the collar. Alternatively the collar may have splined engagement with recesses in the body 11.

Abstract: 1,170,505. Automatic control of gas turbines. CATERPILLAR TRACTOR CO. Feb. 20, 1967 [March 7, 1966], No. 7939/67. Heading G3R. A mechanical flow detector associated with the fuel supplied by a pump to the combustion chamber of a gas turbine produces an electrical proportional signal which automatically controls a valve diverting fuel from the pump away from the combustion chamber. In Fig. 3, rate of flow of fuel through a conduit 17 to the combustion space 16 of a gas turbine is measured by strain gauges 27c, T associated with a lever 23 on which the fuel exerts a pressure. The rate of flow is stabilized by applying the output of a bridge circuit 27, which includes the strain gauges, through transistor amplifiers 55, 80, 81, 56 to control the energization of a solenoid 110 adjusting a valve 13 by-passing fuel through a conduit 18 back to the input of an engine driven pump (not shown) supplying the fuel. A condenser 84 introduces an integral component of control and diodes 63, 66 limit output. An engine speed signal from a tachometer generator 21 is compared with a desired speed signal from an adjustable potentiometer 41, any difference being effective through amplifiers 53, 57 to maintain the desired speed by varying the datum value at which fuel flow is stabilized. When switches 60 are open a further integral component of control is introduced by condensers 61, 76. A resistor-diode network 54 associated with the output of tachometer generator 21 applies to the control system a signal which is a non-linear function of speed to compensate for varying fuel requirements with varying speed. An adjustable resistor network 31A, B ensures a predetermined minimum signal from bridge 27 to prevent flame-out when starting or decelerating.

Class 7(2) In a silencer having its interior subdivided by one or more transverse baffles E<SP>1</SP>, E<SP>2</SP> and E<SP>3</SP>, the or each baffle, as well as the barrel A and ends C<SP>1</SP>, C<SP>2</SP> of the silencer, comprise two thicknesses of sheet metal with an interposed layer L of material which has a permanent sounddeadening effect. The sound-deadening material may comprise fine sand, flue dust, i.e. a by-product of a shot blasting process, wire wool, horsehair or honeycomb cardboard. As shown, baffles comprising two identical metal discs 10 marginally radiused at 11 and secured together by rings 12 divide the interior of a barrel A into expansion chambers of mutually differing volumes, those chambers communicating with each other by way of openings in the baffles or open-ended perforated tubes I, or both. The tubes I, which may have longitudinal ribs, are spaced angularly around a main opening F<SP>1</SP> in the baffle E<SP>1</SP>. A perforated outlet tube J fixed in an opening F" in the baffle E<SP>3</SP> and which may be provided with longitudinal ribs extends into an outlet tube K associated with the wall C<SP>2</SP>. The baffles have angularly spaced, pressed-in recesses 16, preferably on the same pitch circle as the openings H<SP>1</SP>, H<SP>2</SP> and H<SP>3</SP> for the tubes I, producing at the inner sides of the discs 10 complementary bosses 17 facing one another in closelyspaced relation, and similar formations may be provided on the inner faces of the annuli 14, 15 forming the walls C<SP>1</SP>, C<SP>2</SP>.

Abstract: 669,908. Fluid-pressure servomotor-control systems. BOULTON-PAUL AIRCRAFT, Ltd., and NORTH, J. D. March 20, 1950 [March 25, 1949], No. 8213/49. Class 135. In a servo-mechanism comprising a controlled member driven by a hydraulic motor or ram to follow-up the movements of a control member, the motor is supplied with liquid under pressure from a pump of which the delivery is controlled by backlash in an irreversible mechanical drive from the control member to the controlled member. In an embodiment, applicable to the actuation of an aircraft control, movement of control lever 4 acts through chain-and-sprocket gearing 7 to rotate a worm 11 splined on to a shaft 8. Initially, the wheel 12 cooperating with the worm is held stationary due to its connection to the ram or motor 22 and, consequently, the worm slides along the shaft 8, and through a lever 19, moves the reaction member of a variable displacement pump 1 of the radial piston type from the neutral position. Fluid under pressure is thus delivered to the motor 22 which rotates the wheel 12 and its shaft 13, the latter being connected to the aircraft flying control. The movement of wheel 12 causes the worm 11 to be brought back to its neutral position with a similar consequential effect on the pump 1. The electric motor 2 driving the pump 1 also drives a constant output pump 3 which, during normal operation, supplies pressure fluid to cylinders 17, 24 to maintain a locking device 16 and a valve 23, respectively, in inoperative position. Should the power supply fail, valve 23 will be forced by its loading spring to open position interconnecting the two ends of motor 22 to remove the hydraulic lock thereon, and locking device 16 will be forced by its loading spring into a groove in the worm 11 to prevent the latter moving longitudinally. The shaft 13 can then be actuated directly from lever 4 through the chain-and-sprocket gearing and the worm and worm-wheel.
