Title: Improvements in and relating to bridge networks
Inventor: BURGESS CYRIL ARTHUR
IPC: H01P1/213
Filed: 1955-07-21
Abstract: 835,997. Bridge networks. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. July 13, 1956 [July 21, 1955], No. 21181/55. Class 40 (8). The known bridge network of Fig. 1, used, e.g., for connecting two transmitters 14, 15 to a common aerial 10 and a dummy load 11, is improved in that the inductance 12 is provided by a short-circuited transmission line, the electrical length of which from the terminals 3, 4 to the short-circuit is such as to provide an inductive reactance #L=1/#C=Z, where C is the capacitance of the condenser 13 and Z is the impedance of the loads 10, 11. Under these conditions the output energy is equally divided between the two loads if the mean frequency of the transmitters is equal to #/2#. The transmission line is formed by the two pairs of coaxial lines 16, 17 and 18, 19, Fig. 3, one line in each pair being connected to a load and the other to a transmitter. The outer and inner conductors of the coaxial lines are connected in pairs, as shown, by bridge members, the capacitor 13 being connected across the bridges connecting the inner conductors of the pairs of lines 17, 18 and 16, 19. In a known arrangement (Fig. 2, not shown) a lumped inductance is connected across the bridge members 20, 21 and the outer conductors of the lines are short-circuited by a bridge 22 at a distance of a quarter wavelength from their upper ends in order to isolate the upper ends of the outer conductors of the pairs of lines 16, 17 and 18, 19. According to the invention the distance between the upper ends of the lines and the shorting bridge 22 is less than a quarter wavelength and is adjusted to provide the necessary reactance #L. In the modification of Fig. 5 (a plan) the pairs of coaxial lines 16, 17 and 18, 19 pass through metal tubes 23, 24 which form a transmission line short-circuited by the bridge 22 to provide the necessary inductance. The outer conductors of the pairs of lines are connected at their upper ends to the tubes 23, 24 and the inner conductors are connected in pairs, as shown. The two inputs 14, 15 to the bridge can be connected to the outputs of two further bridges and so on.

Filed: 1946-07-16
Abstract: 631,875. Making hand tools. HANNA, M. O. July 16, 1946, No. 21205. [Classes 83 (ii) and 83 (iv)] Forging-machines.-In a method of making spanners or other double-ended articles or tools, 'the opposite end portions only of a bar 1 are first heated to forging temperature by a heavy electric current of low voltage, between end contacts 2 and gripping contacts 3, endwise pressure is applied by means of a piston 5 actuating one of the end contacts 2, to upset the end portions, and then the jaws 3 are opened by hydraulic pistons 4 to allow the current to pass through and heat the whole length of the bar ready for final shaping on a forging machine. The two contacts 2, 3 at each end of the bar are preferably mounted in fixed relationship to each other on a slide 14 so that the distance between them remains constant during the upsetting. A hole 13 in one of the end contacts 2 forms a tong grip 12 on the bar during the upsetting. In a modification, the jaws 3 instead of being bridged by a conductor 10 so that no current passes through the centre portion of the bar, are connected by a resistance, Fig. 7 (not shown), so that some current flows through said portion of the bar to give it a preliminary heating while the ends are being upset. In a further modification both end contacts 2 may be actuated by pistons to move inwardly.

Abstract: 457,290. Regulating delivery of pumps. GREENWOOD & BATLEY, Ltd., Albion Works, and FORBES, C. L., Benridge, Spen Lane, West Park, both in Leeds. July 27, 1935, No. 21368. [Class 102 (i)] [See also Group XXIX] Apparatus for con. trolling the delivery of one or more pumps A, B supplying a hydraulic press or motor, comprises a cylinder M connected to the press or motor by a pipe d and a cylinder L connected through a valve O to a small independent pump Y, the rams of both cylinders being connected to a floating lever G adapted to operate stroke control gear, and the motion of the ram J of the cylinder L being limited by adjustable stops Vl, V<2>. The stops are adjusted by threads of different pitches on a shaft W, and the delivery of the pump Y may be varied. When applied to a press, the pump delivery during the first part of the working stroke is determined by the stop V<1>. The pressure rise due to the press ram coming into contact with the work moves up the ram K to reduce the delivery of the pumps A, B and to operate the valve O so that the pump Y supplies the cylinder L. The ram J rises until stopped by the stop V<2>, and the delivery of the pumps A, B is increased. If the press is of the double action type, its ram will return at maximum speed independent of the setting of the stops V<1>, V<2>,

Title: Method of and apparatus for texturizing thermoplastic yarns
IPC: D02G1/16
Filed: 1974-05-15
Abstract: 1423122 Crimping yarns SCAM ENG SOC RESP LIM 15 May 1974 [15 May 1973] 21573/74 Heading D1F Thermoplastic yarn 2 is texturized by preheating the yarn until it is semi-plastic by contact with at least one heated surface 1, passing the preheated yarn through a crimping zone 10 by a jet of fluid under pressure which is at a temperature such as to maintain the yarn in a semi-plastic state, effecting crimping of the yarn by sudden expansion of the fluid in the zone 10, discharging the fluid as it leaves the zone 10, and collecting the yarn in a stuffer box 11. In one embodiment, Figs. 1 and 3, the yarn 2 is preheated by rollers 1, around which it may be wound one or more times, to a temperature between the second order transition point and the melting point of the polymer constituting the yarn, and is fed to a texturizing means 4 by way, if desired, of a moisturizing chamber 3. The yarn is fed into the inlet 7 of a venturi 8 by a jet of hot fluid, e.g. air or superheated steam, by an injector 5 having a nozzle with a calibrated opening 6. The filaments of the yarn 2 emerging from the outlet 9 of the venturi 8 are crimped by the sudden expansion of the fluid in the zone 10 and the yarn passes into the stuffer box 11. The expanded fluid is discharged from the zone 10 through openings 12 which may lie in a plane perpendicular to the axis of the venturi 8 or may be inclined at an angle of 15‹-30‹ to this plane. The stuffer box 11 may be provided with a stopper device to regulate the density and the time of residence of the yarn therein. Discharge rollers 13 may be provided. Preferably, the inlet cone angle of the venturi 8 is 75‹-90‹ and the outlet cone angle 75‹-110‹. In another embodiment, Fig. 4 (not shown), the pre-heating rollers are replaced by a heated plate (15). Specified yarns are polyamides, e.g. nylon 6 and nylon 66, linear polyesters, cellulose esters, polyolefins, e.g. polypropylene, and polyvinyl and polyacrylic resins.

Filed: 1924-09-12
Abstract: 223,202. Naamlooze Vennootschap Instituut voor Aero-en Hydro Dynamiek. Oct. 8, 1923, [Convention date]. Metal pipes. - In conduits for conveying fluids, having a portion of increasing crosssectional area, the boundary layer of fluid, which is retarded by friction on the conduit wall, is drawn-off by suction through apertures provided in the wall at those places where velocity is converted into pressure. Energy losses due to eddies and detachment from the wall of the conduit are thereby obviated, and the length of the transition portion of the conduit may be shortened considerably. Thus, Fig. 1, in a pipe 11 conveying liquid to a larger pipe 12 where it attains a higher pressure, a pump 16 draws-off the retarded liquid laver from the wall of the transition portion through an annular port 13, a chamber 14, and a pipe 15. Instead of a pump, the flow of the liquid may be used to produce the suction, by means of devices such as Venturi tubes. The suction effect may be regulated by throttling or adjusting the size of the suction ports, which may be placed at various points and connected to different pressure stages of the suction apparatus. Fig. 2 shows two rows of suction ports 116, 117 formed in the discharge pipe of an hydraulic turbine and opening into separate suction chambers 18, 19. The invention may also be applied to passages for turbines, pumps, blowers, and the like, and to discharge pipes for waste gases, &c. Centrifugal force may be used to secure a uniform distribution of the flow velocity over the cross-section before admission to the transition portion. Thus, Fig. 5, a bend 40 may be inserted before the members 11, 12. The invention may also be applied to transition portions in which pressure is converted into velocity. Specification 10980/05, [Class 69, Hydraulic machinery &c.], is referred to.

Abstract: 376,517. Discharge apparatus. RAYTHEON, Inc., 55, Chapel Street, Newton, Massachusetts, U.S.A.-(Assignees of Le Van, J. D. ; 292, Main Street, Cambridge, Massachusetts, U.S.A.) July 29, 1931, No. 21668. Convention date, Aug. 25, 1930. [Class 39 (i).] In a discharge device containing a gas or vapour or a mixture of these, in which electrons for the discharge between main electrodes is produced by an auxiliary cathode, the main electrodes consist of a perforated cathode of extended area through which electrons pass, an anode of extended area and a grid, the anode and cathode being closely spaced apart and the discharge being confined as by insulators, so that no substantial ionization occurs between those electrodes with an applied voltage higher than the ionization voltage of the filling. As shown in Fig. 2, the cathode 20 consists of a wire screen, the edge of which overlaps a mica screen 18 which confines the positive ionization to the lower part of the envelope 11, Fig. 1, containing the auxiliary cathode 17. The anode 23 consists of a metal disc mounted in a grooved lava insulator 21 around which a grid wire 27 is wound. The space between the cathode 20 and anode 23 is less than or equal to the mean free path of the molecules of the gas or vapour having the smallest path. The cathode 20 is maintained at a higher potential than the auxiliary cathode 17 and serves as the anode for the auxiliary discharge. The insulator 21 and mica screen 18 serve to limit the paths between the cathode 20 and anode and thus prevent ionization. The discharge between the cathode 20 and anode is mainly electronic, any ions produced in the space between these electrodes serving to neutralize the space charge. The filling may be a mixture of helium at a pressure of 1À17 mms. and mercury vapour. Dimensions and characteristic curves are given. The voltage between the cathode 20 and anode is higher than that between the cathode 20 and the auxiliary cathode.
