Title: Supersonic jet propulsion nozzle
Inventor: COLVILLE FRANCIS JEFFREY
IPC: F02K1/09
Filed: 1964-08-25
Abstract: 1,009,777. Jet propulsion nozzles. ROLLS-ROYCE Ltd. Aug. 25, 1964, No. 34818/64. Heading F1J. The Specification includes subject matter identical with that described in Specification 1,009,776 but the claims differ. In a modification, the supersonic gas turbine jet propulsion nozzle comprises a fixed cylindrical casing 21 containing a bulbous plug 22 forming a throat 23. Plug 22 is axially movable between a position, shown in full lines, in which throat 23 is upstream of the downstream end of casing 21 to form a convergent-divergent nozzle and a position, shown dotted, in which throat 23 is at the downstream end of casing 21 to form a convergent nozzle. Plug 22 has an outer wall 24 and an inner wall 25 mounted about a tube 26 supported by struts 27 from casing 21. Axial movement of plug 22, running on balls 28 within axial tracks in tube 26, is effected by an electric motor 30 driving a shaft 31 splined to a sleeve 33 having an externally threaded portion 34 running on balls 36 within a fixed nut 35. An extension 41 of sleeve 33 is rotatably received in a cup member 43 secured to an internal wall 44 of the plug. A modified drive mechanism is illustrated in Fig. 5 (not shown). Plug 22 is provided with angularly spaced streamlined members 45 running on rollers 47, 48 within wall 24. Members 45 are pivotally linked to a sleeve 51 running on wall 25 and moved axially by rams 53. Thus movement of sleeve 51 causes radial movement of members 45 into the jet stream to reduce the flow area at throat 23.

Abstract: 487,598. Fluid - friction brakes. POGIOLI, V. Dec. 19, 1936, No. 34967. [Class 103 (i)] Control valve means for a brake of the kind in which the flow of liquid in the circuit of a rotary pump is adapted to be restricted to brake the shaft of the pump comprises a pair of slide valves arranged one at each side of the pump and adapted to be manually positioned so that the flow of the liquid causes one or the other of the valves depending upon the direction of rotation of the pump partially or wholly to obstruct the flow. Conduits 11, 11<1>, leading from a reservoir 4 to the sides of a gear wheel pump of which the wheel 1 may be keyed to a vehicle axle, have disposed within them valves each comprising a slidable cylindrical body 3, 3<1> having a longitudinal slot 12, 12<1> and a transverse slot 13, 13<1> in which slides vertically a block 10, 10'. The bodies 3, 3<1> are adjustably positioned in their casings by pressure liquid supplied through passage 9 from a master cylinder operated by the driver. Normally, the bodies 3, 31 are positioned to the left hand so that the liquid can circulate freely, passing through the slots 12, 12<1> but when they are moved to the right hand, Fig. 4, the blocks are in alignment with the conduits 11, 11<1> and the liquid flow causes the block on the suction side, depending on the direction of rotation of the pump, to move upwards as shown at the left hand of Fig. 1, so that the liquid can still flow freely through the longitudinal slot while the block on the delivery side remains in the lower position and depending upon the position of the body 3, 3<1> partially or wholly obstructs the liquid flow.

Title: Improvements in or relating to screw vices, jacks and the like screw operated devices
IPC: B25B1/10
Filed: 1953-12-17
Abstract: 760,601. Vices. SANDERS, H. B., and SANDERS, B. W. Dec. 10, 1954 [Dec. 17, 1953; June 4, 1954], Nos. 35225/53 and 16666/54. Class 61 [Also in Group XXIV] Screw and nut mechanism applied to a vice comprises an operating spindle 19 provided with screwed portions 13, 18 of different pitches co-operating respectively with a nut 12 on the fixed base 11 of the vice and a nut 20 which is rotatably carried in a cross member 22 secured to the movable member 15. The nut 20 is coupled to the spindle 19 by a torsion spring 26 and on the initial approach movement of the movable jaw 14 to the fixed jaw 10 it rotates with the spindle 19 so that the rate of movement depends upon the pitch of screw portion 13 alone. When resistance to the movement of the jaw 14 is encountered, as when gripping a workpiece, the shoulder 25 of nut 20 is held frictionally by the cross member 22. Relative movement between. the spindle 19 and nut 20 then takes place by the spring 26 being wound up and the spindle advances axially through the nut 20. The movement imparted to member 15 and the movable jaw 14 is at a rate depending upon the difference between the pitches of screws 13 and 18 providing a high mechanical, advantage. On reverse rotation of spindle 19 to release the vice jaws the tensioned spring 26 returns the hut 20 to its original position. In a modified arrangement the nut 20 is initially free from rotational restraint but is adapted upon load to engage a serrated shoulder thereon, with a fixed serrated surface to effect the final. tightening action. In an-. other modification a sleeve is rotatable on the spindle 19 and has an external thread engaging an internal thread on the cross member 22. In this case the helical spring is arranged between the cross member and. the sleeve.

Title: 3,3'-bi-isoxazole
Filed: 1957-11-14
Abstract: Esters of 3-isoxazole carboxylic acid with monohydric and polyhydric alcohols are used as plasticizers for cellulose derivatives.  Thus cellulose acetate is plasticized by the addition of the methyl ester of 3-isoxazole carboxylic acid.ALSO:The invention comprises the new compound 3,31-bi-isoxazole.  It may be prepared by reacting acetylene with nitric oxide at elevated temperature and pressure.  The process may be carried out batchwise or continuously in the presence or absence of an inert diluent, e.g. carbon dioxide, isooctane, toluene, acetonitrile, ethyl acetate, dioxane, cyclohexane, benzene or acetic acid.  Preferred pressures are in the range 100-1500 lbs./sq. inch and preferred temperatures in the range 50-150 DEG  C.  In the examples, 3,31-bi-isoxazole is obtained by reacting acetylene with nitric oxide in the presence of acetonitrile.  In one example, isoxazole-3-aldehyde and 3-cyanoisoxazole are obtained as by-products.  Oxidation of the 3,31-bi-isoxazole with potassium permanganate and sulphuric gives 3-isoxazolecarboxylic acid which is converted to the methyl ester by treatment with diazomethane; it is used as a plasticizer for cellulose acetate (see Group IV (a)).

[Also in Division F3] A combined ram jet and rocket engine has a solid starting propellant 5 contained within a solid main propellant 6, atmospheric air flowing to the main propellant for ram jet operation after combustion of the starting propellant. The starting and main solid propellants 5, 6 are contained within an outer casing 1 having a centre body 3 at its upstream end supported by struts 2 to define an air intake 7. Prior to firing of the propellants, the air intake 7 is blocked at its downstream end by an auxiliary solid propellant 8. A further auxiliary propellant 13 is disposed downstream of a nozzle 11 at the end of the propellant 5, the nozzle 11 itself being formed of a propellant or ablative material so as to burn away during combustion and vary the flow area. The engine is started by igniting propellant 13 which ignites propellant 5 as it burns down and exposes an exit nozzle 12. As propellant 5 burns down it ignites propellant 8 which burns rapidly to form a passage 16 for atmospheric air F entering the intake 7. Propellant 5 ignites a layer of phosphorus 9 which raises the temperature of the main propellant 9 to ensure the initiation of its combustion with the ram air entering through the intake 7. By this time the auxiliary propellant 8 has burnt down to form the profile 17 so that the intake air follows the path S. Additional oxygen is supplied by a chemically fixed solid oxidant 10 stored in the main propellant 6. Further liquid oxidant can also be supplied through injectors 15, when required during air breathing operation, from tanks 14 within the casing 1.

Abstract: 1,060,643. Protective systems. ENGLISH ELECTRIC CO. Ltd. Sept. 9, 1964 [Sept. 12, 1963], No. 35984/63. Heading H2K. To detect arcing faults or other non-linear high resistance faults, e.g. when a conductor of A.C. power supply line falls to earth or when an earth leakage path develops in an underground cable, a protective system produces an output representative of the proportion of higher frequency components in the current through the fault path. The system comprises a corebalance transformer or, as shown, parallelconnected current transformers 13 which produce a signal dependent on the resultant of the line currents, and a transactor 40 which accentuates the higher frequency components of the signal. A series circuit comprising a resistor 41 and a filter 42, 43 is connected across the transactor, the filter presenting a low impedance to the higher frequency components. The voltage across the resistor 41 is proportional to the total signal from the transactor 40 and a transformer 46 connected across the filter produces a voltage dependent only on the fundamental frequency and the lower harmonic frequency components. A comparator unit 47 compares these two voltages and produces an output dependent on the amount by which the fundamental frequency and low harmonic components are less than the total alternating voltage signal, i.e. dependent on the proportion of the higher frequency components in the signal. The output of the comparator is rectified at 17 and operates a relay 18 when it is of sufficient magnitude. A time delay circuit may be connected to the relay 18.
