Title: Improvements in the manufacture of pigmented cellulose derivative compositions and of artificial filaments, films, lacquers, plastic masses, and other materials containing them
IPC: C09B67/20
Filed: 1935-10-10
Abstract: Pigmenting material is incorporated with a plastic mass which has a basis of an organic derivative of cellulose and contains a proportion of oil of the order of 10 per cent or less based on the weight of cellulose derivative, but which at least during the later stages of the process is otherwise substantially free from softening agents for the cellulose derivative.  The pigmented mass thus obtained may be used as a colouring material for lacquers, plastic compositions, and solutions for making filaments and films.  The pigment may be mixed with the cellulose derivative and oil in the presence of a volatile softening medium for the cellulose derivative, substantially all of which is removed during the operation.  Cellulose acetate, formate, propionate, and butyrate, and methyl, ethyl, and benzyl cellulose are specified.  The pigment may be white or coloured.  White pigments specified are tin oxide, antimony oxide, titanium dioxide, tin phosphate, barium sulphate, lead sulphate, calcium sulphate, zinc oxide, zinc carbonate, aluminium oxide, silicon dioxide, barium borate, calcium borate, china clay, talc, mica, diacetyl benzidine, diacetyl tolidine, dibenzoyl benzidine, naphthyl urea, anthraquinone, anthracene, natural and artificial resins.  Coloured pigments specified are ochre, sienna, red lead, chrome yellow, tin bronze, venetian red, vermilion, ultramarine, Prussian blue, milori blue, Guignet's green, verdigris, chrome green, raw ombre, burnt ombre, Vandyke brown, lamp black, carbon black, and graphite.  The pigments may be toned with iron gallate. Castor oil, rape seed oil, chinawood oil, linseed oil, and turkey red oil may be used.  The proportion of pigment may be 20 per cent or as much as 500 per cent on the weight of the cellulose derivative As volatile softening medium there may be used acetone mixed with alcohol, chloroform, ethylene dichloride, ethylene or methylene chloride mixed with alcohol.  The ingredients may be mixed simultaneously or the pigment may be added to the plastic mass of cellulose derivative, oil, and softening medium on malaxating rolls.  The colouring material obtained after thorough mixing and removal of softening medium other than oil may be added to solvents or solutions of cellulose derivatives or natural or synthetic resins which may also contain cellulose derivatives.  In an example, dry carbon black is placed in the bottom of a mixing machine, acetone-alcohol mixture containing castor oil is poured on top, mixing is started and cellulose acetate is added gradually.  The mass is worked on malaxating rolls, being drawn through the rolls several times, and the bulk of volatile solvent is evaporated.  The mass is re-mixed and taken off as a sheet which is dried and then cut or broken into chips.  These are dissolved in a solution of cellulose acetate in acetone.  The solution is extruded to form black filaments.

Title: Improvements in or relating to Flash X-Ray Generation Methods and Apparatus
Inventor: OWEN WILLIAM DENLEY
IPC: H01J35/22
Filed: 1966-06-27
Abstract: 1,172,528. X-ray tubes. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 22 June, 1967 [27 June, 1966], No. 28812/66. Heading H1D. In a method of generating a flash X-ray pulse, a high voltage pulse is applied in a vacuum between a control electrode and a filamentary cathode heated to an electron-emitting temperature by passing a current through it, such that the control electrode is positive with respect to the cathode, the amplitude of the pulse being sufficient to cause the cathode to operate under " temperature and field-emitting " (TF) conditions, i.e. high field and high temperature, and a high voltage positive pulse is simultaneously applied between the anode and cathode or control electrode to accelerate electrons to the anode to generate X-rays thereat. If the positive anode pulse has a negative overswing then the deviation of the cathode/control electrode pulse is less than that of the anode pulse, moreover, the amplitude of the anode pulse may be varied independently of the control electrode pulse to enable X-rays of any desired energy to be produced at constant dosage. As shown in the X-ray tube of Fig. 2, the anode may be a cylindrical rod 1 coaxially surrounded by eight filamentary cathodes 3 and eight grid wires 2 forming the control electrodes. A shield 4 surrounding the anode and filaments assists in focusing electrons on to the anode and protects the glass envelope (not shown) from electron bombardment. A vacuum of 10<SP>-9</SP> Torr. is preferably used. In another form of X-ray tube, Figs. 3 and 4 (not shown), the cathode filaments and control electrodes are constituted by alternate closed rings. Each series of filaments and control electrodes may be replaced by an open helix of wire. Examples are given of typical dimensions and operating conditions.

Title: Improvements in and relating to the waving of hair
IPC: H05B6/50
Filed: 1945-10-31
Abstract: 617,245. Hair waving by electro-magnetic induction heating. BRIGGS, G. Oct. 31, 1945, Nos. 28878, 28879, 28882, 28883, and 31631. [Class 39 (iii)] [Also in Groups XIV and XXXV] In a method of waving hair, the tresses of hair, before or after treatment with a suitable reagent, are wound on curlers constituted by, or associated with, elements of high-permeability metal in which heating currents are induced by a high frequency electromagnetic field produced about the curlers: The field is applied to each curler in turn. For example, a tress 18 of hair is wound from root to tip on a curler 17, of a metal of high permeability, over which an inductor 15, housed in the barrel of a "gun," is adapted to be slipped. The inductor 15 is connected to an adjustable tuning coil 14 which is coupled to the output coil 13 of a high frequency generator 11. Excessive heat at the centre of the curler may be distributed by a split sheath of a non-magnetic metal of good heat conductivity, e.g. aluminium. Alternatively the inductor coil may comprise two magnetically-opposed halves, as described in Specification 617,246. The curler may be covered by a sleeve or wound-on strip of a porous material which may carry suitable reagents. External heating of the tress of hair may be ensured by providing an outer split sheath of high-permeability metal, which may be lined with an absorbent lint for carrying suitable reagents. A curler on which the hair is wound from tip to root comprises closely packed wires 51 of high-permeability metal; end plugs 52 of the same metal about which are disposed inductor coils 40, 41, and a split sleeve 50 of aluminium or other non-magnetic metal, which is so spaced from the wires 51 that it is uniformly heated. Protective thermostatic control-circuits [see Group XXXV] are described. Specification 617,322, [Group XXXV], also is referred to.
Patent GB-1188479-A (GB)
Title: Optical Filter
Inventor: HEEK HERMAN FREDERICK VAN
IPC: G02F1/09
Filed: 1968-06-18
Abstract: 1,188,479. Light modulation apparatus. MULLARD Ltd. 18 June, 1968, No. 28928/68. Heading H4F. [Also in Division G1] The temperature of a body X is measured by passing the radiation emitted from the body through a polarizer P, a Faraday effect device FE and an analyser A, operating the device FE so as firstly to reject radiation at a first wavelength and then to reject radiation at a second wavelength, and detecting the intensities of the radiation transmitted by the analyser in each case, and then comparing the detected intensities. The ratio between the intensities of radiation at two different wavelengths is different at different temperatures and so by the use of calibration curves, the ratio measured may be used to determine the temperature of the body. In order to reject the two different wavelengths the device FE is chosen to be of a kind that rotates the plane of polarization in dependence on wavelength of the radiation passing through it, as well as on the magnetic field strength applied to the deivce. A suitable material for device FE is Yttrium iron garnet (YIG) or such garnets doped with Gallium (for the iron) and Terbium (for the yttrium). In the example described, the two wavelengths rejected are 1À15Á and 1À9Á (in the infra red region). By application of a square wave alternating voltage and a D.C. voltage from battery 3 to coil 1, two different levels of field strength H 1 , H 2  are applied to the device F.E. With the analyser A and the polarizer P in alignment, and by suitable arrangement of the field strengths H 1 , H 2 , it is arranged that on the half cycles when field H 1  is applied, radiation at 1À15Á. is not transmitted by the analyser A, since radiation at this wavelength has been rotated through 90 degrees with respect to the polarizer (and analyser). Radiation at 1À9Á however is only rotated through 45 degrees and so is partially transmitted. Intermediate wavelengths are transmitted in varying proportions between these levels. All radiation above a certain wavelength near to but higher than 1À9Á is absorbed by a filter F(g). On half cycles when the field H 2  is applied, 1À9Á radiation, having been rotated through 90 degrees, is cut out, while 1À15Á radiation rotated through 180 degrees is passed. To detect the two different intensity levels and compare them, either a single detector D is used, the output of which is switched alternately along lines 5, 6 to a ratio-measuring device 7, or separate detectors individually sensitive to the two wavelengths 1À15Á and 1À9Á are used to avoid the need for switching. If the A.C. source is not a true square-wave (e.g. sinusiodal) peak detectors are used in the detector circuitry. Two manually switched D.C. sources may be provided to provide the levels H 1 , H 2  of the magnetic field as required. The detector(s) may be of the germanium or lead sulphide type.

Title: Improvements in or relating to receivers for time modulated electric pulses
IPC: H04J3/00
Filed: 1946-09-27
Abstract: 617,440. Pulse modulation; pulse-shaping circuits. STANDARD TELEPHONES & CABLES, Ltd. Sept. 27, 1946, No. 28953. Convention date, Feb. 23, 1945. [Classes 40 (v) and 40 (vi)] Push-pull time-modulated pulse signals are demodulated by deriving triangular demodulating pulses from the signal pulses delayed thereafter by a given time and mixing these demodulating pulses with subsequently occurring signal pulses. Signal pulses 3, 4, 5, 6, Fig. 2, are delayed to form pulses 3a, 4a, 5a. and shaped to triangular pulses 3b, 4b, 5b, upon which the original pulses 4, 5, 6 are superimposed. The further the pulse pairs, e.g. 3 and 4, are modulated apart the lower they appear on the sides of the demodulating pulses, which are themselves still time modulated, the two effects being cumulative. The mixed signal is either clipped at level 20 and passed through a low-pass filter to extract the audio output 21, or is amplified and clipped by a peak riding clipper before being filtered. The receiver, Fig. 1 (riot shown), has a further shaper which may be switched into circuit so that the signal pulses also are shaped to triangular pulses, Fig. 4 (not shown), before being mixed with the demodulating pulses. The degree of overlap between the two sets of pulses varies with the modulation, varying the area of the peaks, which are clipped and filtered as before. In a suitable delay and shaper circuit, Fig. 5, signal pulses 38 applied to a saw-tooth generator 37 produce saw-tooth waves 39, which are in turn applied to a multivibrator 40 which is biassed so that it is triggered shortly before the peak of each saw-tooth to produce square pulses 42. These are then shaped by network R4, R5, C5 to a substantially triangular shape 43. The Specification as open to inspection under Sect. 91 also discloses the use of rectangular demodulating pulses which are added to the signal pulses to form width modulated pulses. This subject-matter does not appear in the Specification as accepted.

Abstract: 799,650. Retardometers; recording-apparatus. CHANGY, G. DE. Sept. 21, 1956 [Sept. 23, 1955], No. 29010/56. Classes 106 (3) and 106 (4). Recording-apparatus comprises a disc 39 on which the different decelerations to which the apparatus is subjected are recorded in substantially radial lines and is characterized by means 28, 25 for rotating the disc 39 through the same angle after each deceleration is recorded. An arm 22, carrying an inertia block 21, is urged against a stop 43 by a compression spring 31, guided by a rod 33, and upon a deceleration the arm 22 swings anticlockwise about its pivot 23 causing a stylus 45 to record an arcuate line on the disc 39. The disc 39, which may be of waxed paper, is clamped by a nut 42 between a glass plate 40 and shoulder 41 of a shaft 26. The shaft 26 has secured thereto a ratchet wheel 25 restrained against clockwise movement by a detent 27 and advanced anticlockwise by a pawl 28 upon return movement of the arm 22. The pawl 28 is urged against the ratchet wheel 25 by an arm 22 and is prevented from driving it more than a tooth at a time by a cam 44. The disc 39 is graduated in concentric circles over the full range of decelerations normally anticipated and a record mark extending beyond these circles indicates that the apparatus has been subjected to a shock forcing the block 21 against a spring-loaded plunger 36. The apparatus is housed in a casing 48, a hinged lid 53 gives access for disc changing, an arcuate slot is provided for the stylus 45 to work in and an arrow on the lid indicates the correct orientation in which the apparatus should be mounted.
