Title: Improvements in or relating to a method of treating a tow of filaments or threads
IPC: D01D10/00
Filed: 1947-03-10
Abstract: A continuous tow of filaments 1 is treated by passing it into a liquid contained in an annular trough 3 rotatable about a vertical axis whilst liquid is passed continuously from the pipe 8 on to the solid centre portion from which it passes into the trough and rotates with a mean speed substantially equal to that of the trough.  The tow is piled into the trough by means of the oscillating arm 4.  The liquid flows from trough 3 through the perforated bottom 5.  If necessary more than one trough may be used and these may be on separate axes or concentric with each other.  In an example, a solution of groundnut globulin is coagulated and the tow of filaments is stretched and passed over roller 2 and guide 4 into trough 3 from which it is later withdrawn over roller 9.  It is stretched between rollers 9 and 10 and then piled into <PICT:0623460/IV (a)/1> <PICT:0623460/IV (a)/2> trough 12 and later withdrawn by roller 17 and stretched again while passing through the bath 19 situated between rollers 17 and 18.  It is then piled into the inner trough 13 and finally withdrawn over roller 23.  Trough 12 is supplied with liquid at 15 p  and liquid is withdrawn at 16, the rate of flow being such that there is substantially no relative movement between the liquid and the trough.  Similarly, trough 13 is supplied with liquid by pipes 21 and liquid is withdrawn by pipe 22.ALSO:<PICT:0623460/IV (c)/1> <PICT:0623460/IV (c)/2> A continuous tow of filaments 1 is treated by passing it into a liquid contained in an annular trough 3 rotatable about a vertical axis whilst liquid is passed continuously from the pipe 8 on to the solid centre portion from which it passes into the trough and rotates with a mean speed substantially equal to that of the trough.

Title: Light intensity and colour modulating device
IPC: H04N5/66
Filed: 1936-03-05
Abstract: 473,061. Light-valves. ROSENTHAL, A. H. March 5, 1936, No. 6634. [Class 40 (iii)] A device for varying the intensity, colour, or polarization of light comprises two finely dispersed substances in optical contact, their dispersion curves (i.e. refractive index n plotted against wavelength #) ao, #o, Fig. 1, intersecting at a wavelength #o, so that light of wavelength #o passes through the mixed medium, while light of other wavelength is scattered. An electrostatic or electromagnetic field is applied to the medium to split the dispersion curve of at least one of the substances, e.g. #o, into two dispersion curves #1, #2, corresponding to the ordinary and extraordinary beams which are plane polarized at right-angles. The wavelengths for which the medium is homogeneous are then #1, #2 and light of these wavelengths passes through the medium without scattering. The scattered light 11, Fig. 2, passing through is stopped by an aperture 8. The two wavelengths #1, #2, will vary with the magnitude of the applied field, and since they are plane polarized at right-angles, either may be extinguished by a Nicol prism so that the wavelength of the emergent light will vary with the applied field. This may be used in colour television, the applied field being derived from signals representing the colour of successive picture points. When used as an intensity modulator, light from a monochromatic source is used in conjunction with a filter passing the same wavelength, more or less light passing through in accordance with the applied field. When a magnetic field is used, it is applied in the direction of the light beam, and the two light beams of different colour are right and left-hand circularly polarized. The medium may be powdered glass in nitrobenzene, an emulsion of two liquids, a mixture of two solids ; however, at least one of the substances must exhibit the Kerr or Faraday effect. The device should be maintained at a constant temperature, which may be varied to adjust the intersection of the two dispersion curves.

Title: Improvements in or relating to thermionic amplifiers
IPC: H03F3/28
Filed: 1937-03-08
Abstract: 491,803. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., and STRONG, C. E. March 8, 1937, No. 6814. [Class 40 (v)] In an amplifying system particularly adapted to high-frequency power amplification, a driving amplifier and a driven amplifier feed power in series into a common load in such a manner that the driven amplifier is excited by the output from the driving amplifier and that at the drive voltage necessary to produce a predetermined plate swing in the driven amplifier, the driving amplifier delivers sufficient power to provide the current required in the output load as determined by the driven amplifier and in addition any incidental power losses in the grid circuit of the driven amplifier. Fig. 2 is an application to push-pull amplifiers. The driving amplifier 1 is a known neutralized push-pull amplifier the output of which is fed through the output transformer across the resistance 3 to the cathodes of the driven amplifier 2. The grids of amplifier 2 are earthed so that the plate voltage is in series and in phase with the driving voltage with the result that amplifiers 1 and 2 feed power in series into a load resistance 4. The inductance of the grid earth leads is neutralized by condensers 5 and 6. The direct plate voltage may be applied to the two amplifiers in parallel as shown or in series as in Fig. 4 (not shown). The filaments of the amplifier 2 are at a high frequency voltage and are fed through high impedance reactors or through a shielded transformer, Fig. 6, having earth shields 9, 10 between the primary and secondary windings and shields 11, 12 surrounding the secondary windings. The input high-frequency tuning coil 13 forms an anti-resonant circuit with the capacities between shields 9 and 11, and 10 and 12. For grid modulation of the output the first amplifier is fed with modulated waves or is modulated by grid voltage variation, and for plate modulation, modulation voltages are applied to both plates simultaneously.

Title: Improvements in or relating to electric switches incorporating means for dousing with extinguishing fluid, arcs arising on separation of the switch contacts
IPC: H01H33/915
Filed: 1952-03-17
Abstract: 735,934. Fluid-blast switches. CALOREMAG ELEKTRIZITATS-AKT.-GES. March 17, 1952 [March 15, 1951; March 17, 1951; April 2, 1951; April 2, 1951; June 18, 1951; Aug. 4, 1951], No. 6897/52. Class 38 (5). In an oil or gas-blast switch, the arc struck between the hollow movable contact 1 and fixed contact 2 is extinguished by fluid driven from within a movable pumping piston 5 through a nozzle 6 into an arcing chamber 9 and thence via vents 8 into an outer chamber 10 at considerably lower pressure, the vents 8 being of such size that the minimum fluid-pressure within the chamber 9 is adequate for arc-extinction whilst the wall 3 of the chamber 9 can resist the maximum pressure. In the closed position the piston rests on contact 2 and is, in opening, picked up by a ring 12 on the contact 1 engaging a shoulder 13 on the piston, this engagement slowing - the movement of the contact to give arc-extinction at a short gap. In closing, the contact 1 may move independently of the piston, but preferably the two are locked at 25, the lock being released by a ramp 30 in the closed position. With high internal opening pressures, a ring 14 is forced upwards against springs 17, valves 28 allowing filling of the piston during closing. A spring-buffered piston ring 21 enables high pressure to be built up in the chamber 9. Alternatively, elastic gas containers or solids may be provided to absorb these pressures. The above may be adapted for a back-to-back arrangement of two series breaks with an additional mechanical blast applied between, so as to issue from, the two fixed contacts (Fig. 2, not shown), or applied to the spaces within the pistons 5 (Fig. 3, not shown). As a modification of the last-named arrangement, the pressure in the chamber 9 may act on one face of a differential piston, the opposite face of which communicates with the interior of the pumping piston to give an added blast (Figs. 6, 7, not shown). In Fig. 8, the movable contact is made of differing overall diameters, whereby the aperture 83 is filled by the thick part 82 in the extinguishing position shown and remains so until the switch is almost fully open, whereas in closing, when the aperture is freed and similarly an aperture 86 in the piston is cleared by the part 12 of the movable contact, fluid can enter the piston. In all forms, the tubular contact 1 is vented at 23 to the space 10.
