Abstract: 933,835. Combing machines. T.M.M. (RESEARCH) Ltd. March 28, 1962 [April 4, 1961], No. 12064/61. Class 120 (1). A combing machine has a rock-shaft positioned below and behind the pivots about which the comber heads swing. Each comber head includes a frame 1 carrying upper and lower nippers 2, 3 and a feed roller 4, the frame swinging on pivots 5 when actuated by the rockshaft 6 through levers 7, 8 and link 9.

Title: Improvements relating to indicating systems for dynamo-electric machines adapted to be connected to a common bus-bar
IPC: H02J13/00
Filed: 1927-05-05
Abstract: 271,443. British Thomson-Houston Co., Ltd., (Assignees of Finney, A. C.). May 21, 1926, [Convention date]. Protective arrangements.-A green lamp 27 is illuminated when none of the alternating current generators 3 - - 6 is connected to the bus-bar 7, and a red lamp 22 is illuminated when two or more of the generators are connected by their associated switches 13 - - 16 to this bus-bar. The generators are connected to the supply bus-bar 9 through switches 8, only one phase being shown, and the bus-bar 7 is the earthed neutral, it being desirable to have not more than one generator connected thereto because of the possibility of circulating currents, especially those of triple frequency. When all the switches 13 - - 16 are open, the associated series connected contacts 12 are bridged and the lamp 27 is illuminated from a supply 23. Closure of any switch breaks the circuit, and completes another at the associated contacts 17 through a resistance 26 and coil 19 of a differential relay, but the current through this coil is insufficient to cause movement of the relay. However, if two or more of the switches 13 -- 16 are closed, then a corresponding number of resistances 26 are connected in parallel, and consequently the current through the coil 19 is increased sufficiently to cause closure of the relay contacts 20, 21 and the illumination of the lamp 22. In a modification the contacts 12 are omitted and the relay is provided with centering springs, so that with no switches closed, one relay contact is closed to illuminate the green lamp and' also ring a bell, with two switches closed the relay is centred, and with more than two another contact is closed to illuminate the red lamp and ring another bell.

Abstract: 768,540. Centrifugal separators. DIEFENBACH, A. April 28, 1955 [May 13, 1954], No. 12318/55. Class 23 In a separator comprising a rotary drum 9, a light liquid component c is removed from the drum by a suction pipe 5, a heavy liquid component b discharges through holes 14 and over the lip of the drum, and solid impurities a are intermittently removed from the drum by a scraper (not shown). The drum is mounted at one end of a shaft 11 driven by a pulley 12 and carrying a brake drum 13. After the drum has been charged with water from a pipe 8, the juice from crushed olives is fed to the drum through the pipe. The light liquid component (oil) is removed by the suction pipe which is adjustable radially by a hand-wheel 6. The heavy liquid component (fruit water) is discharged into the casing 2 which has an outlet 15. When the impurities reach the holes 14 rotation of the drum is stopped, and the oil and water is removed by the suction pipe. The remaining impurities are removed by a scraper (Figs. 1 and 2, not shown) which is combined with a discharge shoot and is radially adjustable by a hand-wheel.

Or the lower end of the socket may be conical, and the outer surface beneath the flange f may be grooved diagonally. The plug d has a flanged cap j and is screw-threaded to a point near the underside of the cap so that when the plug is screwed down to force the washer i against the socket flange f, the flange k of the cap bears against the rubber surrounding the socket.

Title: Improvements in or relating to electrical apparatus for providing an indication of the standing wave ratio in an electromagnetic wave transmission means
Inventor: DIX JOSEPH CHARLES
IPC: G01R27/06
Filed: 1957-04-17
Abstract: 886,656. Standing-wave ratio measurements. GENERAL ELECTRIC CO. Ltd. April 17, 1958 [April 17, 1957], No. 12622/57. Class 37. In apparatus for providing an indication of the standing-wave ratio in electromagnetic wave transmission means 3, a sweep frequency oscillator 2, sweeping at 50 c.p.s., causes an electromagnetic wave of varying frequency to be propagated along the transmission means, a signal being derived which is dependent upon the amplitude of that portion of the wave which is reflected back along the transmission means, and a comparison of the derived signal with a reference signal is provided whereby variations in the standing-wave ratio in the transmission means with frequency are indicated. Directional couplers 9, 10 supply signals ; respectively dependent upon the incident and reflected waves in the waveguide 3; to contacts 13a, 13b of switch 13 whereby they are selectively fed to terminal 20a of a vibrating switch 20 operated at 25 c.p.s. from a 50 c.p.s. A.C. source 25 by way of frequency divider 28; the other terminal 20b being earthed ; and two traces are thereby provided on cathode-ray tube 23, having a 50 c.p.s. time-base, and indicate the amplitude of the signal from switch 13 relative to earth. Comparison of the traces obtained in either position of switch 13 provides an indication of the variation of the standing-wave ratio in waveguide 3 with respect to frequency. The signal at terminal 13a is also fed back to oscillator 2 by way of comparison circuit 15 to stabilize the oscillator output. Blanking by feeding the output from the source 25, after phase-shifting at 26 and squaring at 27, to the control grid of the cathode-ray tube ensures that a display is shown only when the frequency of oscillator 2 is swept in one direction.

Title: Improvements in multiphase generator and bus system

Abstract: 1,263,853. Protective arrangements for polyphase generating systems. GENERAL ELECTRIC CO. 17 March, 1970 [29 April, 1969], No. 12715/70. Heading H2H. A polyphase power generating system comprises a generator having a plurality of polyphase winding sets each set having a separate neutral connection; a plurality of current responsive impedances by means of which each neutral connection is separately connected to earth and a plurality of sheathed bus sections having conductors connected to the winding sets and the sheaths connected to earth. A power generator 20 comprises two three-phase windings ABC; XYZ, electrically spaced by 60 degrees and having neutral connections N, M which are connected to earth by way of current responsive impedances 21, 22 in the form of transformers having secondary windings connected across resistors. The system further ineludes bus sections 23, 24, 25; each of which is provided with a sheath 23f connected to earth, and a pair of conductors 23a, 23b supported by standoff insulators 23c, 23d and separated by a dielectric shield 23e composed of two spaced insulating sheets. The conductors 23a, 23b in section 23 are connected to phases C and Z of the generator windings with similar connections for the sections 24, 25, thus the bus conductors in each section carry substantially antiphase currents. With a generating system so arranged, neutral to ground currents under fault conditions are limited by the impedances 21, 22 and line-to-line fault currents are reduced. The dielectric stresses in the sheaths are also reduced. In other embodiments the bus section conductors may be arranged coaxially or the bus sections may each only comprise one conductor in which case the conductor may be arranged to carry a reduced current by arranging the associated generator as a nine-phase machine.

Abstract: Vulcanized rubber which contains cellulosic material, e.g tyres or belting, is reclaimed by comminuting, mixing with an oxidizing agent as a solid or liquid, heating, and sheeting between rolls to plasticize the rubber.  The oxidizing agent, e.g. hydrogen or other peroxide, a persulphate, a chlorate, or a hypochlorite, may be used with a little acid, e.g. hydrochloric or phosphoric acid, and wetting agent, e.g. 1/2 per cent of sulphonated "Lorol" (Registered Trade Mark).  The rubber may be sheeted by passing five times through grinding rolls, the tendered cotton being reduced to a fine powder dispersed in the rubber. Hydrogen peroxide and hydrochloric acid are preferred as they leave no residue to be washed out.ALSO:Vulcanized rubber which contains cellulosic material, e.g tyres or belting, is reclaimed by comminuting, mixing with an oxidizing agent as a solid or liquid, heating, and sheeting between rolls to plasticise the rubber.
