Title: Production of shrink-resistant wool
Inventor: GOLDBERG ALAN AUGUST
IPC: G06F17/18
Filed: 1964-05-07
Abstract: Wool and wool-containing materials in a continuous length, e.g yarns, tops and woven and knitted fabrics, are shrink-proofed by wetting them out with an aqueous liquor containing (a) a wetting agent, e.g. an anionic or nonionic wetting agent, (b) a halogen-containing shrink-resistance-imparting oxidising agent for wool, e.g. sodium or potassium dichloroisocyanate or an alkali metal hypohalite, and (c) a source of hydrogen ion other than a per acid in an amount sufficient to reduce the pH value of the liquor to below 5, the anion of the source of hydrogen ion being inert with respect to the halogen-containing oxidising agent, immediately after wetting out passing the wetted-out material through the nip between a pair of rollers to ensure that the material is uniformly impregnated with a controlled amount of the liquor while maintaining the controlled amount of the liquor in contact with the material until at least a desired amount of the halogen-containing oxidising agent has reacted with the wool and feeding metered quantities of aqueous solutions of the halogen-containing oxidising agent, the wetting agent and of the source of hydrogen ion into the aqueous liquor to maintain a substantially constant composition, the quantities being correlated with the rate of pickup of liquor by the woollen materials being treated so that (a) the volume of liquor remains substantially constant and (b) complete renewal of liquor takes place in 1-15 minutes.  The source of hydrogen ion may be hydrochloric, sulphuric, acetic or trichloroacetic acid, sodium or potassium hydrogen sulphate or sodium dihydrogen phosphate.  The material may be wetted with the aqueous liquor either by immersion for 1-2 seconds or by spraying and the pickup of aqueous liquor or the nip may be 50-250%.  The treated material may subsequently be washed with water, passed through a dilute aqueous solution of a reducing agent, e.g. sodium sulphite, again washed with water and finally dried.

Title: Process and apparatus for treatment of organic compounds
IPC: C07C4/16
Filed: 1962-05-18
Abstract: The destructive hydrogenation, pyrolysis or dealkylation of hydrocarbons in the gaseous state mixed with hydrogen is effected by contact with a metallic filament heated to 1,000-1,500 DEG  C., whereby atomic hydrogen is formed at the filament.  Petroleum or coal gas by-products are treated to obtain products from which benzene, naphthalene, phenol and pyridine are readily obtainable together with methane, ethylene and acetylene, alkyl aromatics are dealkylated with concommitant desulphurization while dealkylation of o-cresol yields some benzene and toluene and of lutidines yields sone benzene.  The electrically-heated filaments may be bare tungsten wires or platinum mesh (e.g. as a cylinder) preferably arranged parallel to the axis of the reactor.ALSO:The dealkylation of alkyl aromatic compounds is effected in the gaseous phase in the presence of hydrogen and a metallic filament heated to 1000-1500 DEG  C. at which atomic hydrogen is formed.  In examples o-cresol yields a product including phenol and 2,4- and 2,5-lutidines, a product containing pyridine and methyl pyridines as well as hydrocarbon products.

Title: Improvements in or relating to television time base circuit arrangements
IPC: H04N3/185
Filed: 1965-05-07
Abstract: 1,089,444. Converting. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. May 7, 1965 [May 12, 1964], No. 19357/65. Heading H2F. [Also in Division H3] In a line time base for television apparatus, the E.H.T. supply Vh for the cathode-ray tube 16<SP>1</SP> is stabilized by an auxiliary tube 2, or transistor, arranged to be conductive once during each cycle so as to feed additional energy into the output transformer in such a way as to compensate for changing load on the E.H.T. supply. Fig. 3 shows a line output stage for a colour television receiver comprising an output tube 1 (or transistor), efficiency diode 11, boost capacitor 13 and E.H.T. rectifier 17. A D.C. control voltage, the magnitude of which is indicative of the current taken by the cathoderay tube 16<SP>1</SP>, is derived by rectifying flyback pulses at 12 by means of a voltage-dependent resistor 40. This control voltage is passed via the cathode circuit of tube 1 to the cathode of tube 44, the anode of which is supplied with flyback pulses 47 so as to provide a control voltage for tube 2, arranged to increase the anode current of tube 2 to compensate for increase in cathode-ray tube current. Tube 2 is also supplied with a waveform 25, derived from the line drive waveform 3 which arranges that tube 2 is only conductive during the forward stroke of each sweep. Alternatively, waveform 25 may be inverted and the sense of winding 18 reversed so that tube 2 is conductive during flyback periods. The boost capacitor 13 may alternatively be connected between windings 6 and 7, or, as in Fig. 1 (not shown), may be conventionally connected between the lower end of winding 7 and the Vb supply. Fig. 1 (not shown) relates to a line output stage suitable for use with a cathode-ray tube of the indexing, apple, chromatron or Lawrence type. In that circuit, the control voltage for the stabilizing tube 2 is supplied independently of tubes 1 or 44. The amplitude or duration of waveform 25 may alternatively be controlled in dependence on the E.H.T. load instead of using a D.C. control voltage for tube 2.

Filed: 1945-07-30
Abstract: 630,956. Photo-finish. CROWLEY, R. E. July 30, 1945, No. 19502. [Class 98 (i)] A mirror is set up on the opposite side of a track from a photo-finish camera so that, additionally, images of the far sides of objects passing the camera are recorded on the film for the purpose of facilitating identification of the objects. Timing means, also on the opposite side of the track and travelling in the field of view of the camera may be recorded on the film as well, to enable the time elapsing between the passage of the several contestants to be determined. Apparatus,' as in Fig. 2, is placed in the field of view of a photo-finish camera (not shown) at the winning post of a race track, the apparatus consisting in a cabinet 11 carrying a mounting plate 30 on which is mounted the mirror 36, which has a width equal to the field of exposure of the camera and a length sufficient to reflect the entire width of the race track into the camera, and which is adjustable in position by means of a hinge and wing-nuts 31. A window 16 in the cabinet 11 enables exposure of the timing means, which means consist of a drum bearing timing indicia 23, 24 and driven at a speed approximately equal to the speed of the contestants. Fig. 5 indicates the type of picture produced by the apparatus and shows, in the case of a horse race, how a horse which is shielded from the camera, by another horse running between it and the camera, is clearly visible in the reflected image which is placed above the direct image; and thus the several horses may be identified even when they arrive badly bunched together. The time interval between the arrival at the winning post 55 of horse 1 and horse 4, which is not obtainable from the direct image because of obscuration, may be calculated from the position of a projected line 56 from the reflected image of the horse 4 on to the image 24 of the timing indicia. Specifications 537,253 and 540,936 are referred to.

Filed: 1922-07-21
Abstract: 200,710. Marks, E. C. R., (Freyn, Brassert, & Co.). July 21, 1922. Hinged valves; materials, special.-A valve for a regenerative hot-blast stove is so counterweighted that although the counterweight tends to open it and hold it open it will remain in either opened or closed position without locking mechanism. The valve 25, shown closed in full lines and open in broken lines, is hung from an arm 34 of a rock-shaft 37, which, outside the valve casing, carries a gear segment meshing with a similar segment 51 on the counterweight shaft, and the relative arrangement is such that the counterweight exercises its maximum effect on the valve in the closed position, although insufficient to open it, while in the open position, the weight of the valve is taken almost entirely by the shaft 37 and its bearings. The valve is hung connected to its arm by a partly spherical bearing so as to bed automatically on its seating, and its under side is faced with two layers of refractory cement with an intervening layer of expanded metal. Jack bolts 21 are provided for lifting the valve casing to withdraw the seating 23 for repairs &c.
