Title: Improvements relating to turbojet engines
IPC: F23R3/00
Filed: 1957-11-08
Abstract: 818,490. Aircraft jet propulsion plant. GENERAL MOTORS CORPORATION. Nov. 8, 1957 [Nov. 9, 1956], No. 34865/57. Class 4. [Also in Groups XII and XXVI] A turbo-jet engine tailpipe comprises pivoted vanes adjustable to block off or restrict access of the propulsive gases to the nozzle, gas discharge ports in the jet-pipe wall upstream of the vanes, slidable closure members to open or close the ports, and a connection between the vanes and closure members whereby the ports are opened when the vanes are moved to the blocking position. Fig. 5 is a part axial section of the tail pipe, comprising a fixed inner wall 9, a fixed central bullet 8, and a movable outer cowling 7. Four circumferentially spaced master vanes 10 are mounted on radial spindles 11 in the duct between the bullet 8 and wall 9. Each spindle 11 is connected by linkwork, Fig. 10 (not shown) to the cowling 7, so that on rearward movement of the cowling, the vanes are turned from the broken line position of Fig. 5, where they offer minimum obstruction to the gases to a blocking off position, Fig. 3. Between the master vanes 10 are mounted follower vanes 22 on radial spindles 26 connected by levers 27 to a ring member 25, to which the inner ends of the master vanes are connected as at 23. Rotation of the master vanes rotates ring 25 about the engine axis, and thus also rotates the follower vanes. Rectangular ports 36, in two groups of five, communicate with grids of deflecting vanes 37 and slidable closure members 40 connected at 55 to cowling 7 and provided with seals 49, 53. The cowling is movable by a jack (not shown), so that as movement of the cowling rotates the vanes 10 and 22 to the blocking off position, ports 36 are opened. Intermediate positions for the vanes and closure members may be used. Radial walls 38 separate the ports. A central tube 35 is supported from cowling 9 by four hollow struts (not shown), three of which are connected to a supply of cooling air, and feed tube 35 with air to cool the turbine. The follower vanes 22 may function as afterburner fuel injectors (see Group XII).

Abstract: 972,342. Jointing and terminating highvoltage cables. JOSLYN MFG. & SUPPLY CO. Sept. 18, 1962 [Oct. 3, 1961], No. 35526/62. Heading H2E. A high-voltage cable is sealed into a cable termination or joint box by a preformed sleeve of dielectric elastomer which is slightly tapered so that as it is forced into the housing so the sleeve/cable and sleeve/housing interfaces move progressively forward expelling any entrapped air. In a termination for a concentric cable 25, Fig. 1, the sleeve 31 is placed over the dielectric 27 of the cable and is forced into the porcelain housing 11 by bolts 34, 35 acting on a fitting 29, which is lined with a soft metal stress relief cone 30. Pressure is applied to the top of the sleeve 31 by a compression spring 32. The original tapered shape of the sleeve 31 is shown chain dotted. The outer (neutral) conductors 26 of the cable are bunched and clamped to the fitting 29, Fig. 2 (not shown), and the lower end of the stress cone 30 has fingers 36 which contact the semi-conductive tape 28 beneath the neutral conductors, and a flange 30a which contacts the metallizing on the outside of the housing 11. In a modification, Fig. 5 (not shown), for terminating a lead-sheathed cable, the conical fitting 29 is replaced by a cylindrical one, and the intervening space is occupied by a member of conductive plastic, cemented to the lower end of the sleeve 31, and having approximately the same hardness as the sleeve. This member contacts the conductive tape beneath the lead sheath and forms the stress cone. In another modification, Fig. 6, a lead-sheathed cable is terminated in an oil-filled transformer 50 by sealing it into a porcelain housing 56 with a sleeve as above described, the housing 56 being bolted to the transformer and sealed by a ring 54. The cable core is gripped by a silverlined contact socket 64 formed by two halves of a diaphragmed connector 63 held together by a band spring 62. The diaphragmed connector 63 provides a seal against oil-flow. In another modification, Fig. 8, two lead-sheathed cables 70, 71 are jointed within a two-part metal housing 72, 73 and insulated by a split sleeve 81 of dielectric plastic immediately surrounding the cable connector 80, the assembly being sealed within the housing by a sleeve 78 which tapers equally towards the ends from the middle. The ends of the sleeve 78 are conical and are fitted with sleeves 79 of conductive plastic for stress distribution. The ends of the housing 72, 73 are closed by inserts 85 and conductive plastic fillers 86, with compression springs 87 between the fillers 86 and the sleeves 79 so that the sleeve 78 is compressed as the two halves of the housing are drawn together by bolts 76. In all cases the cable and inside of the housing are coated with silicone grease during assembly. The dielectric sleeve, 31 or 78, is made of polyurethane, or alternatively of silicone or neoprene, and the conductive plastic elements of P.V.C.

Abstract: 913,368. Pulse radar. ALBISWERK ZURICH A.G. Oct. 22, 1959 [Oct. 22, 1958], No. 35861/59. Class 40 (7). Apparatus for photographing a target and a missile includes radar means for measuring the distances between the camera and the target and the target and the missile, and means for releasing the camera shutter when the distance-difference is less than a predetermined amount. A synchronizing pulse generator triggers pulse transmitter 2, Fig. 4, which feeds aerial 5 via duplexer 3; reference voltages from aerial unit 4 are compared in known manner with the modulation voltage impressed on the video signal in receiver amplifier 8 due to conical beam scanning so that the aerial automatically follows the target. The video signal is fed also to a distance discriminator 9 together with the output of distance gate pulse generator 14, the latter being fed from phase shifter 13, and an error voltage from discriminator 9 is fed back to the phase shifter. In control stage 10 the distance gate pulses cause the a.g.c. applied to i.f. amplifier 7 to become effective only when target echoes occur. Aerial 18 is directed to the expected target position and is fed from transmitter 2; missile echo video output from unit 21 is fed to display 12 and to coincidence circuit 23 the other input to which arrives from distance gate 22 provided for selecting missile echoes to the exclusion of others and preceding the gate in unit 14 by a fixed interval corresponding to an equation derived from the geometry of the problem, Figs. 1 and 2 (neither shown). On coincidence in circuit 23 the camera shutter is released. Phase-shifter 13 comprises a phantastron, a blocking oscillator and a delay line in series, Figs. 7 and 8 (neither shown). Coincidence circuit 23 includes a gate 112, Fig. 9, fed with missile echoes, Fig. 10, a, and distance gate circuit 22 output, Fig. 10, b, to generate pulses, Fig. 10, c, then lengthened in circuit 113, Fig. 10, d. The latter pulses, together with the output, Fig. 10, e, of a blocking oscillator 116 which is triggered by circuit 22 output after delay in line 117, are fed to a " box-car " circuit 115 which forms waveform, Fig. 10, f; the latter is integrated Fig. 10, g, by circuit 119 before application to a Schmitt trigger 120, Fig. 10, h, which actuates a relay 121, Fig. 10, i, controlling an electromagnetic camera shutter-release mechanism. In a modification, account is taken of the relative velocity of the target and missile as calculated by a known device fed with target and missile velocities, the target velocity being determined by known means from the targettracking radar data and the missile velocity being obtained from ballistic data and missile position, Figs. 5, 11 and 12 (not shown). In a further arrangement, the missile fire direction is the same as the line to the target and a single transmitter and aerial are used, Figs. 3 and 6 (neither shown).

Patent GB-360377-A (GB)
Abstract: 360,377. Zeroizing-mechanism. PETTERS, Ltd. and PETTER, G. B., Westland Works, Yeovil, Somerset. Aug. 1, 1930, No. 23258. [Class 106 (i).] Zeroizing mechanism for key set and operated calculating machines comprises means for causing the actuating mechanism to rotate the numeral wheels to predetermined positions and means whereby, upon the return of the zeroizing mechanism, a transfer is initiated throughout the wheels to complete the zeroizing operation. The invention is described as applied to a machine having a partial keyboard and actuating mechanism as set forth in Specification 360,375 and two forms are shown. In the first, all the numeral wheels are turned to " 9'' and the lowest wheel is subsequently moved one tooth while in the second the lowest wheel is turned to " 0 " and the others to " 9," transfer being held up until the return movement of the zeroizing handle. In the first form, Figs. 1 and 4, depression of the keys 8 causes the swinging of a lever 9 about its pivot 10 and the consequent rocking of a segment 7 actuates the numeral-wheel pinion 1. Zeroizing is effected by rocking an external handle connected to a bar 16 pivoted on the axis 10 and connected by springs 17 to levers 15 which cause the rocking of the segments 7 to actuate the numeral wheels. At the same time a projection 21 of the bar 16 moves away from a lever 22 and allows a spring 24 to rock the lever 22 to move fingers 25 into the path of stops 26 on the numeral wheels, to arrest them in the " 9 " position. A pawl 31, Fig. 4, is pivoted to the lever 22 and contacts with the lowest pinion 1. During the return of the lever 22 this pawl actuates the pinion by one step and causes a transfer throughout the totalizer. In the second form, Fig. 5, the lever 32 controlling the segment 7 is pivoted at 33, the zeroizing bar 16 being pivoted on the same axis and being connected by springs 17 to levers 35 which actuate the levers 32. The lowest wheel is arrested at zero, the others at " 9," the arresting mechanism not being shown. To prevent transfer until the return of the zeroizing mechanism, the bar 16 engages a projection 30 on the lowest transfer lever 27. Specification 360,376 also is referred to.

A fluid coupling comprises a turbine 9 on a shaft 2 and an impeller 4 carrying a casing 5 and a reservoir 6 mounted on shaft 2 via bearings 7, 7a with seals 8, 8a, and having centrifugally operated inlet valves 14 and outlet valves 19 disposed 90 degrees apart (the shown section being along two planes at right angles), and the wall section of the turbine 9 consists of a radial wall 9b inclined towards an inner cylindrical wall 23. At rest valves 19 are open; on rotation of impeller 4, fluid circulates in chamber 11 and moves down the inclined wall 9b of the turbine 9 to bounce upon the cylindrical surface 23 and lose energy before flowing back to reservoir 6 via the still open valves 19; as the speed increases, valves 19, 20 close and valves 14 open, the fluid being kept circulating in the outer part of chamber 11 so no energy is lost at surface 23 and full torque is transmitted, Fig. 3 (not shown). If the turbine 9 is overloaded, fluid will first strike surface 23, Fig. 4 (not shown), and if the coupling does not recover by the energy loss and produced slip, the impeller is subsequently slowed down until when the stalling speed of the prime mover is approached the valves 19 open and fluid flows, after dissipation of its energy, to reservoir 6, the inlet valves being closed, causing a decrease in torque to enable the prime mover to recover.
