Patent GB-666368-A (GB)
Title: Improvements in the treatment of cellulose acetate textile materials
IPC: D06M11/05
Filed: 1949-09-30
Abstract: Textile materials comprising mixed yarns composed of staple fibres of acetone-soluble cellulose acetate of acetyl value (expressed as combined acetic acid) 49-57 per cent and staple fibres of cellulose acetate saponified to an acetyl value of 42-45 per cent are subjected to heat and pressure in the presence of moisture.  Preferably the partially saponified cellulose acetate has an acetyl value of 44 per cent, and is used in amounts approximately equal to the amount of acetone-soluble cellulose acetate.  The yarns may be treated as such or in the form of fabrics.  Fabrics treated by the process of the invention retain their shape and have reduced creasing tendencies. The treatment may be carried out by passing the moist material through heated calender rolls at a temperature between 150 DEG  and 200 DEG  C., or by treatment with saturated steam at a pressure of from 20 to 30 pounds per square inch, giving a temperature of 110-120 DEG  C.  The steam treatment may be continuous or batchwise.  The treated yarn may be finished in conventional manner.  Treated fabrics may be dyed, waterproofed or given other finishing treatments.  In an example a fabric produced from yarns composed of equal quantities of staple fibres of cellulose acetate of 56 per cent acetyl (calculated as acetic acid) and partially saponified cellulose acetate of 44 per cent acetyl is moistened and passed between calender rolls at a temperature of 175 DEG  C.

Title: Means for the cancellation of stationary images on cathode ray oscillograph screens
IPC: H01J31/08
Filed: 1944-12-15
Abstract: 588,155. Radiolocation ; cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. Dec. 15, 1944, No. 26262. Convention date, Dec. 20, 1943. [Claeses 39 (i) and 40 (v)] Means for cancelling stationary images on a cathode-ray oscilloscope comprise a second cathode-ray tube with a mosaic screen, supplied with similar scanning and image signals to the viewing tube, which has a signal collector associated with the mosaic from which signals are applied to an electrode of the viewing tube to reduce the intensity of the stationary images thereon. The apparatus is stated to be particularly useful in preventing the burning of dark trace tube screens in radar receivers by stationary echoes. Signals from radar receiver 16 and amplifier 17 are fed to control grids 20 and 21 of tubes 1 and 7 ; grid 20 is normally biassed to cut-off but an incoming echo signal causes an electron flow to the small element of mosaic 3 at which the beam is directed. Mosaic 3 and viewing screen 8 of tube 7 are scanned in unison by scanning generator 10 and if the echo signal recurs each scan in the same place, the mosaic element concerned becomes charged to such an extent in the course of a number of scans that electrons pass to collecting ring 5 producing a signal fed through amplifier 11 to the cathode 12 of tube 7. This signal applied to cathode 12 is used to reduce or cancel entirely the image of the object on tube 7. The gain of amplifier 11 or the sensitivity of tube 1 may be varied to control the amount of cancellation of the image. For moving objects, the mosaic elements do not charge sufficiently for electrons to pass to ring 5 and the images of these objects are produced at full intensity on tube 7 ; full indication of fixed objects is also give for a short time interval after any change of the field viewed.

Filed: 1926-10-11
Abstract: 287,188. Carpmael, W., (Powrie, J. H.). Oct. 11, 1926. Colour photography, screen processes for.-In the production of multi-colour screens, and more especially long screen films, coloured lines are photographically printed in succession on one side of the support by the aid of a line matrix formed on, and temporarily integral with, the other side of the support. In producing a threecolour line screen, a film 6, Fig. 1. is sensitized on one side and printed through a film 1 having opaque lines parallel to the length of the film and half the width of the transparent interspaces. The pointing lamp 18 (e.g. an elongated mercury vapour lamp) is provided with shields 37 and mounted on a curved guide 33, Fig. 2. The developed film 6 has opaque lines twice as wide as the opaque interspaces. The opposite face of the film is sensitized, as with bichromate, and printed through the back with the lamp 18 at one end of the curved track 33 to produce oblique illumination. After exposure and washing to remove unexposed colloid, the lines are dyed and mordanted in one colour. The film is resensitized and again printed through the back with the lamp 18 towards the other end of the track 33 so as to produce another set of intermediate lines, which are dyed a second colour. The black and white line matrix is then removed by a solvent and buffing wheel, the film re-sensitized on the front, and exposed through the back to obtain the third coloured line by developing and dyeing as before. During the second and third printing, the already coloured lines protect the sensitive coating superposed on them. The screen surface is then varnished and sensitized for negative production, and a positive can be reproduced on a similarly formed screen film by the method described in Specification 287,388. Specification 20662/05 also is referred to.

Title: Improvements relating to safety devices for railway and like crossings
IPC: B61L29/26
Filed: 1924-10-27
Abstract: 224,224. Holm, H. T., and Westfelt, A. U. Nov. 2, 1923, [Convention dale]. Operating barriers by treadles and the like.- Railway barriers or signals or both at road-crossings are actuated to the roadclear position by gravity and are reversed by expansion under control oi an electromagnetically operated valve, of air which is compressed in a reservoir by a passing train. The barrier 2 normally occupies the roadclear position under the action of the counterweight 4, and the piston 14 is fully Lome in the cylinder 15, to which position it was moved by the last train. A train approaching the crossing completes the circuit to the the solenoid 25, the armature of which trips the valve lever 23 which is held tripped by the catch 28. Liquid is then forced by the compressed air in the reservoir 17 into the, cylinder 15 and the piston 14 is moved outwards, and through the lever 8 and rope 6 the barrier is closed or the signal set at danger. A stop 32 on the rope releases the catch 28. As the train passes the crossing, a ramp 11 meets the roller 10 and moves the piston 14 inwards thereby recompressing the air in the reservoir 17 through a non-return valve, and at the same time releases the rope 6 to allow the counterweight 4 to restore the barrier or signal.
