Title: Axial Flow Compressor
Inventor: FORGE-DEDMAN ANTHONY SYDNEY DE
IPC: F04D21/00
Filed: 1965-07-28
Abstract: 1,153,134. Axial-flow compressors. A.S. DE FORGE-DEDMAN. July 27, 1967 [July 28, 1965], No. 32335/65. Heading F1C. [Also in Division F2] An axial-flow compressor comprises at least one stage having a rotor capable of discharging at supersonic velocity, an annular flow passage downstream of the rotor having a portion which decreases in cross-sectional area in the downstream direction to reduce the supersonic flow to subsonic velocity by way of a single annular shockwave located in the flow passage, and stator vanes located downstream of the location of the shockwave to reduce the subsonic swirl. The rotor blades 300 of each stage of an axial-flow compressor are of impulse design, producing a relative velocity which is supersonic from inlet to outlet of the blades, the absolute velocity at outlet also being supersonic with a Mach number of 1 to 2À5. Downstream of the rotor blades 300 is an annular flow passage which is initially convergent to decelerate the flow to a subsonic velocity at an annular shock-wave 302 which compresses the fluid. Thereafter, the passage is parallel-sided. There may be a sudden enlargement at the transition between these two parts of the passage to accommodate the thickened boundary layer which occurs immediately downstream of the shock-wave. In the case of the final stage, the passage may include a further section of divergent form to reduce the exit velocity. As shown, the axial position of each shock-wave may be adjusted by moving the inner or outer wall 304 of the convergent part of the passage by means of a rack and pinion 305. Stator vanes 307 are also adjustable. Both adjustments may be effected simultaneously by a piston 306 in response to changes in the fuel system pressure, the piston being operated hydraulically, pneumatically or electromagnetically. Holes may be provided in the passage wall to permit boundary layer suction immediately upstream and/or downstream of each shock-wave. Particularly if the compressor is being used by itself without being followed by a conventional axial-flow or centrifugal compressor, it may be necessary to provide one or more blow-off valves which are opened when starting the compressor to accelerate the air to supersonic flow.

Abstract: 1280542 Angular bending TSENTRALNY NAUCHNO-ISSLEDOVATELSKY INSTITUT TEKHNOLOGII MASHINOSTROENIA 28 June 1969 32775/69 Heading B3E A method of bending a pipe 5 comprises heating within an induction heater 6 a portion of the pipe to be bent, withdrawing a part of the heated portion from the induction heater at a speed exceeding the speed of heat transfer due to the conductivity of the pipe, while the part being withdrawn is simultaneously cooled to narrow the heating zone, axially compressing the pipe, and bending the heated portion of the pipe whilst the pipe is being axially fed and axially compressed. In operation, the pipe 5 is inserted through the opened jaws 21 and 22 of a clamp 3, a sprayer 7 and inductor 6, and a bending unit 8 until the pipe end bears against a stop in a carriage 46. The pipe is then heated in the bending zone to 900-1000‹ C. and moved axially by the carriage 46 with the simultaneous cooling of the heated part of the tube emerging from the inductor 6 by a sprayer 7. Movement of the pipe is continued until a constant width of heated zone is obtained whereupon the jaws 21 and 22 clamp the pipe. Since the carriage 46 continues to move, a preliminary axial compression of the pipe is ensured before a shaft 15 is rotated. As the shaft is rotated the movement of the carriage 46 by motor 54 on a gear train is stopped so that movement of the carriage can be controlled by the interaction of a roller 40 with a raceway 41. As the pipe is bent by the bender 8, pneumatic cylinders 27 of supporting elements 4 are actuated one after the other thus pressing supporting surfaces 25 against the bent section of the pipe.

Filed: 1954-11-12
Abstract: 761,209. Strengthening edges of sheet material. BOS, C. VAN DEN. Nov. 12, 1954 [Nov. 14, 1953; Nov. 14, 1953], No. 32841/54. Class 42 (1). [Also in Group X] An assemblage of parallel boards, 1, 1a, 1b, Fig. 1, placed edge-to-edge, as in a shuttering panel, are interconnected at their ends by connecting members 3 which permit the boards to move relatively thereto upon expansion and contraction of the assemblage in the direction widthwise of the boards, and are connected together along their abutting edges to prevent the formation of gaps between the boards. The connecting members for the ends may consist of a metal bar 3 having a circular hole 5 for a screw 4 passing into the end of one of the boards 1, and having elongated holes 7 for screws 6 passing into the ends of others of the boards, for example 1a and 1b, to allow relative transverse movement of the boards upon expansion or contraction. In another form, the bar 3 is connected to the ends of the boards by screws 12, Fig. 4, passing through cavities 15 in the ends of the boards and screwed into rockable pins 13 located in the board at right-angles thereto, whereby the screws are capable of rocking to permit the relative transverse movement of the boards upon expansion and contraction.

Abstract: 1,271,974. Welding by fusion and pressure. TEXTRON Inc. 30 June, 1969 [1 July, 1968], No. 32937/69. Heading B3R. [Also in Division F2] In a method of manufacturing a rolling bearing in which the outer race ring 12 is fractured along a groove 18 to allow insertion of the inner race 16 and rolling elements 14, the outer race ring is rejoined by fusion welding the adjacent ends of the race at the fracture 20. A beam of charged particles, e.g. an electron beam is directed at one end of the fracture at a radially outward portion of the fracture. The beam melts the race along the bottom of the groove 18 and on removal of the beam, the fused material coalesces to weld the two ends of the race together. The fusion is controlled to occur so quickly that the raceway surface is not affected. The beam may be directed at the race radially instead of axially and the beam may traverse along the axial length of the fracture or pulses of electrons may be used to provide overlapping or space stitches. In an alternative embodiment, an insert 40 is placed in the groove 18 and the beam applied to melt the edges of the insert and the race. Alternatively the insert may be secured by resistance welding, one electrode being connected to the insert and the other to the edges of the groove.

Title: Improvements in or relating to electrical regulating systems
IPC: H02P5/56
Filed: 1957-10-24
Abstract: 835,966. Control of two D.C. motors. BROWN, BOVERI & CIE A.G. Oct. 24, 1957 [Oct. 24, 1956], No. 33233/57. Class 38 (3). [Also in Group XXXV] The speed of an electric motor 1 is made to correspond with variations in a reference voltage derived from a potentiometer 21 having a reciprocating slider, the motor being supplied from a Ward-Leonard generator 2. The speed of the motor is detected by means of a tachometer generator 5 which supplies voltage to a regulating device 4, this voltage being compared with the reference voltage obtained from the potentiometer 21 so that the field winding 3 of the generator is excited in such a manner as to reduce any deviations of the speed from the desired value at any instant. The circuit comprising the machines 1, 2 is duplicated by a circuit comprising motor 11 and generator 12, the motor 11 being controlled in the same way as the motor 1 by means of tachometer generator 15 and regulating device 14 which is connected to generator field winding 13. As shown, the slide arm of the potentiometer 21 is coupled to the shaft of the motor 11 so that it performs a reciprocating motion when the shaft makes one revolution. The speed of the motor 11 follows variations in the reference voltage with accuracy since the motor is not subject to load variations. Because the motor 1 is subject to load changes, and in order to reduce these, the two motors are coupled to tachometer generators 10, 20 and additional control signals are produced to eliminate substantially any differences in the relative motor speeds. In another arrangement, the additional control signals are derived from deviations in the relative angular positions of the motors. For this purpose, the motors each drive a single-phase synchronous generator excited with three-phase current. The outputs of the generators are connected to a phase-sensitive rectifier, and, as long as the angular positions of the motors coincide, the rectifier has zero output. Any difference in the angular positions causes the rectifiers to produce an output which is applied to the regulator 4 for correcting the angular deviation.

Title: Selective tint correction circuits
IPC: H04N9/64
Filed: 1971-07-16
Abstract: 1361274 Colour television RCA CORPORATION 16 July 1971 [22 July 1970] 33529/71 Heading H4F Flesh tone correction of a displayed colour television image is carried out by adjusting the phase of the reference signal fed to the colour demodulators. In one embodiment, Fig. 1, the red and green colour difference signals are matrixed at 18 to produce an I signal. If this signal is positive (indicating a flesh tone component) switch 20 is opened to allow an amplitude limited chrominance signal from 24 to pass via phase shifter 21 to the output of a manual tint control 11. The phase shift of phase shifter 21 is set so that for a chrominance signal of +I phase the outputs of phase shifter 21 and tint control 11 are in phase, so that demodulation is unaffected. A chrominance signal with a +I component will cause the demodulating reference signal to be rotated towards the I axis. For a negative signal from matrix 18 switch 20 is closed and demodulation is unaffected. In a second embodiment, Fig. 2 (also Fig. 3, not shown), the modifying signal is obtained by a phase detector 32 which produces an output of the phase difference between a phase shifted signal from the reference oscillator and a phase shifted amplitude limited chrominance signal, this output being zero for a + I chrominance signal. The output is fed via a filter 36 to remove the subcarrier components to a modulator 37 which also receives an input of the amplitude limited chrominance signal. The output of the modulator 37 is passed to a tint network 38 to be added to the reference signal. The phase detector 32 is arranged to have no output if either of its inputs is missing.
