Title: Yarn winding process and yarn package
IPC: B65H54/38
Filed: 1964-08-07
Abstract: In a yarn winding process for forming large yarn packages free of ribbons the bobbin is driven at a constant peripheral rate of speed-for example by a drum-and the yarn is traversed-for example by grooved roll-back and forth across the bobbin from a station separated from the bobbin at a traversal speed which is constantly varied in a regularly cycled pattern at such a frequency-for example 4-10 cycles per minute-as to prevent maintenance of ribbon forming ratios for a period of time sufficient to form the ribbons of the yarn package.  The winding is continued beyond the point where the ratio of the peripheral speed of the bobbin and the average traversal speed establishes a primary ribbon forming ratio.

Title: Improvements relating to decoding circuits for directional radar pulses
Inventor: HULME VERNON BOYCE
IPC: G01S1/02
Filed: 1957-10-15
Abstract: 902,432. Radar. ELECTRIC & MUSICAL INDUSTRIES Ltd. Oct. 13, 1958 [Oct. 15, 1957], No. 32263/57. Class 40 (7). A circuit, particularly for use in a radar system of the type wherein the relative amplitudes of received pulses are indicative of the misalignment between the axis of the aerial system and the line of sight to the target, comprises a bridge circuit. Fig. 1 (part shown). In the case of a radar system using four squint beams, signals being received from each beam in turn, misalignment in azimuth and elevation results in the reception of echoes of different amplitudes on the different beams, as a, b, c and d, Fig. 2 (part shown). The azimuth error e (x) is (a+c) - (b+d) and the elevation error # (y) is (a+b) - (c+d). To obtain # (y) a similar circuit is used but with a different waveform fed to the suppressor grids. The voltage e(x) is developed across a storage capacitor C6. Operation of the azimuth misalignment circuit.- The suppressors of a pair of pentodes V5, V6 are biased to inhibit anode current even in the presence of positive strobe pulses E on their grids, and are fed with potentials varying as lines A and B. The strobe pulses, which may be obtained from a range tracking unit so that the bridge is receptive only to echoes from a given target, are applied to the grids of V5, V6 which conduct alternately, and cause the upper and lower pairs of bridge arms also to conduct alternately. After a number of cycles the bridge reaches a steady and symmetrical state, similar components in the arms having similar values. Assuming that conduction to the anode of V5 causes the upper arms to conduct and to the anode of V6 the lower arms to conduct and that all the echoes are positive pulses, arrival of an echo a will result in an incremental charging of capacitor C6. Echo b arrives when the lower arms are conducting and causes capacitor C5 to be charged negatively. At the subsequent strobe pulse echo c increases the charge on C6 while the negative charge on C5 causes it to decrease. Echo d charges C5 negatively and again, in the subsequent pulse, this reduces the charge on C6. After a number of pulses a, b, c, d have been received the integrated increments of charge C6 will cause the voltage appearing across the capacitor to approach # (x) very closely.

Title: Explosion gas turbine plant and method for operating the same
IPC: F02C5/12
Filed: 1952-12-19
Abstract: 759,842. Gas turbine plant. SCHILLING ESTATE CO. Dec. 19, 1952 [Dec. 24, 1951], No. 32271/52. Class 110(3) A multistage gas turbine fed with combustion gases from explosion chambers has the inlet and exhaust pressures of each stage controlled so that the pressure drop across each stage is constant during expansion and so that the stages may each be formed with a single row of blades some of which have a circumferential speed of 250 metres per second or more. The invention described with reference to a gas turbine plant is described in Specification 759,840. The counter pressures are determined so that the energy may be utilized in a wheel having a single row of blades having a circumferential velocity of over 250 metres per second and preferably of about 300 metres per second. This is stated to result in stage efficiencies of between 75 per cent and 85 per cent. To cool the rotor, coolant is passed from an inlet 25 through a tube 28 to a space 32 where it is reversed and passed into the space 36 between the tube 28 and bore 29. The tube 28 has collars 30 which space it from the bore 29 to form a series of spaced annular channels. The coolant flows from the space 36 and bore 40 into the peripheral cooling channel 42 where it cools the feet of the blades 13 and is returned from this channel through the bore 43 into the channel 37 From the channel 37, the coolant flows through the bore 39, cooling channel 41 for the blades 8 and bore 44 to the discharge outlet 48. The outlet 48 may be connected to a re-cooling apparatus whose discharge is connected to the inlet 25. Specifications 288,321, 288,322, 315,366 [all in Class 51(i)], 410,049 and 759,841 also are referred to.

Title: Selective removal of boron compounds from silane
IPC: C23C16/22
Filed: 1959-09-23
Abstract: Boron-containing impurities, e.g. B2H6, are removed from silane by contacting the impure silane with sodium, lithium, rubidium, potassium, cesium, barium, calcium, strontium, or magnesium metal, or an amalgam thereof, in the form of finely-dispersed particles on an inert carrier medium, to form a complex compound between the metal and the boron-containing impurities, and separating the silane from the complex compound. The metal or amalgam may be dispersed on an adsorbent carrier, e.g. activated carbon, or alumina, silica gel, porous clay, or natural, or synthetic, zeolites, such as faujasite, wellsite, chabazite, or Zeolite A or X.  Alternatively, the amalgam of the metal may be used without dispersion on an inert carrier medium. The silane in gaseous phase may be contacted at -112 DEG  to 400 DEG C. at atmospheric, or superatmospheric, pressure. Subatmospheric pressure is preferred when an adsorbent carrier is used. Specifications 777,232 and 777,233 are referred to.
