Patent GB-732421-A (GB)
Title: A process of applying coloured designs on fabrics
IPC: D06P5/24
Filed: 1953-07-15
Abstract: 732,421. Transferring designs. WOOLDRIK, G. J. L. July 15, 1953, No. 19636/53. Class 100 (2). Designs are transferred to fabrics, such as cotton cloth, or painter's canvas treated or not with linseed oil, by first applying thereto a solution or an emulsion of a polyvinyl, polyacryl or other synthetic resin susceptible to swelling by oil (so that the ink of the transfer will be bound thereto by penetration) in a small proportion, e.g. not exceeding 20 gms. per sq. m., so that the structure and appearance of the fabric remain substantially unaltered, and then applying by the decalcomania method a transfer printed on paper by a fatty printing ink. In an example a cotton fabric of weight 290 gms. per sq. m. is coated by a doctor blade with polyacrylonitrile in aqueous dispersion to contain, when dry, 10 gms. per sq. m. of the resin ; after a light rubbing with a fat talcum to prevent adherence of the transfer paper, a multicolour transfer is applied, e.g. in a heated calender giving a temperature of 50-180‹ C. and a pressure of 3-10 atmospheres ; the backing paper is then removed, e.g. by wetting. The fabric may then be washed, slowly dried, stretched on frames, and varnished. It is stated that two or more successive prints may in some cases be obtained from a single transfer paper.

Title: Improvements in the method of constructing armatures for dynamo electric machines
IPC: H02K15/12
Filed: 1920-07-09
Abstract: 151,243. Apple, V. G. Sept. 15, 1919, [Convention date]. Coils and conductors; commutators; cores; insulation.-Armatures for dynamo-electric machines are constructed by applying pressure to stacked laminµ coated with a liquid condensation product to make the core self-supporting, coating the winding with a condensation product and applying pressure and heat to reform the winding, and then applying a second coating of condensation product with greater heat and pressure to form an armour covering. The laminµ are coated and pressed so as to form a structure which is self-supporting and which may be bound integrally to its spider, while in the press, by an intervening layer of heat-hardened condensation product. The coils are then wound and impregnated and the wound core is placed in a mould in which the conductors are pressed into uniform configuration. The condensation product is partially hardened by a preliminary hot pressing operation at this stage. After cooling, the armature is placed in another mould 18, Fig. 5, and commutator bars 20, having connecting-wires 23 placed in holes 24, as shown in Fig. 6, are inserted. Additional insulating material is placed so as to form, under the greater pressure and heat applied, the commutator support 21 and the armour covering 24. The mould may carry pins which enter the holes in the commutator bars and support them during the pressing operation. The Specification as open to inspection under Sect. 91 (3) (a) comprises also claims for an armature having its component parts and commutator held together by or its wires coated with an adhesive which is substantially unaffected by oils, insoluble in water and resistant to heat. It also comprises claims for an armature having its coils covered with or cemented to its core by a condensation product. This subject-matter does not appear in the Specification as accepted.

Patent GB-940845-A (GB)
Title: Improvements in method and apparatus for providing substantially uniform charged particle irradiation across an object to be irradiated
IPC: G21K1/08
Filed: 1961-06-02
Abstract: 940,845. Discharge apparatus. GENERAL ELECTRIC CO. June 2, 1961 [June 20, 1960], No. 19951/61. Heading H1D. In irradiating an object by a scanning beam of charged particles, e.g. electrons, emerging from a window of a generating tube, the beam is arranged to have, in the plane of the window, a non-uniform density distribution having a maximum on either side of the midpoint of the distribution in order to counteract the effect of electron scattering and so obtain a uniform distribution at the level of the object. A uniform energy distribution may be obtained concomitantly at the object. In one arrangement, two, three, or even four or more tubes, are arranged side-by-side, the outer beams having asymmetrical density distributions and the inner beams having the normal density distribution with a maximum at the centre, the beams together producing the overall desired distribution. In a single tube arrangement successive electron bursts are produced on alternate sides of the mid-point of the window, succeeding bursts being swept in opposite directions. To do this the deflection sweep frequency is an odd integral multiple of one-half the accelerating voltage frequency; preferably it is equal to one-half that of the accelerating voltage. The amplitude of the sweep voltage and its phasing relative to the accelerating voltage may be varied. The electron beam pulse may be asymmetrical with respect to time, successive pulses forming mirror images to each other. This may be achieved by overloading a resonant transformer supplying the accelerating high voltage to the tube, by varying the amplitude of the sweep voltage or by delaying a biasing control pulse supplied to the control grid of the tube relative to the peak of the accelerating voltage sine wave. This latter method may be applied to the multi-tube arrangement. In the generating tube shown, the accelerating electrodes 34 are supported by metal spacers 12 of the envelope. The envelope terminates in a flared metal end section 20 closed by a beam exit window and anode 21 of e.g. aluminium or titanium. The scanning system may be electrostatic or magnetic and the beam is scanned both longitudinally and transversely of the window, the frequency of the latter movement being much higher than that of the former movement. The charged particles may be positively charged particles. Where an object of irregular shape is irradiated, the density distribution may be varied to conform to the shape of the object.

Title: New or improved process and plant for the extraction of fatty and other matters by means of volatile solvents
IPC: C11B1/10
Filed: 1922-07-21
Abstract: 183,825. Zipser, S. July 27, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Fats and fatty oils, extracting by solvents.- In the extraction of fats by volatile solvents the extract is forced out of the extractor by solvent vapours from a separate source, preferably those from the still in which the extract is distilled, aided or not by a suction pump. The extract may be preheated before admission to the still by waste vapours from the still and extractors, the residual solvent may be removed by steam or by solvent vapours, and preferably all operations are carried out without admitting air to the apparatus. In the operation of the apparatus shown the inter-connected extractors E<1>, E<2>, E<3> are charged, closed, and exhausted by a pump R. Solvent from a reservoir L is sent by a pump P &nd pipe a to fill the first chamber say E<1> of the series, and is then displaced by fresh solvent into the second chamber say E<2> through valve d<1>, pipe G, and valves e<2>, f<2>, and in a similar fashion into the third chamber E<3>. When extraction in the chamber E<1> is sufficient, vapours from one of the stills D', D<2> are admitted by a pipe I, valve n<1>, and pipe x<1> to expel the solvent into the chamber E<2>, that in E<2> into E<3>, and that in E<3> by way of the valve d<3>, pipe G<1> and valves e<1>, m<1> and m to a preheater V and one of the stills D<1>, D<2>. The residual solvent in E<1> is removed by steam from a pipe F and valve i<1>, the steam and vapours passing by valves x<1>, o<1> and pipe I' to the heating coil J of the preheater V and then to a condenser K, waterseparator W, and the solvent to the reservoir L. The chamber E<1> is then recharged, exhausted, and made the third of the series, E<2> becoming the first. The stills D', D' are heated by coils receiving steam from a pipe H and valve w<1>, w' and, to remove the last traces of solvent from the extract, by direct steam through valves t', t<2>.

Patent GB-799347-A (GB)
Title: Improvements in and relating to the counting of particles and the like
IPC: G06M11/04
Filed: 1955-07-12
Abstract: 799,347. Photo-electric particle counters. LOEB, H. W. July 11, 1956 [July 12, 1955], No. 20154/55. Class 40 (3). Apparatus for counting particles in the form of an outer opaque ring surrounding a central translucent region comprises means adapted to scan the particle field in a raster with a spot of radiant energy, means to generate electric signals characteristic of the passing of the spot on to, and off, a particle and means controlled by a passing-on signal for delaying generation of a passing-off signal. An inhibitor pulse is generated from the passing-on signal, is delayed by one line scan period and prevents throughout its duration the generation of a passing-off signal. To make the inhibitor pulse length dependent on particle size, the scanning speed is increased above normal on passing-on and reduced below normal (conveniently, to zero) on passing-off, the resultant speed being equal to normal speed. A particle, see Fig. 2 (a), is intercepted between G and H in the nth scanning line and between J and K and L and M in the (n+ 1)th line; an inhibitor pulse, see Fig. 2 (c), is generated from nth line scanning, is delayed for one line period and used to prevent generation of a passing-off signal when point K is reached. In Fig. 3, light from a scanning raster produced on the screen of C.R.T. 12 is directed into transparent carrier 15 bearing the particles, is collected by condensing lens system 16 and passed to photocell 17 whose output is fed via amplifier and amplitude discriminator 21 to deflection modulator 20 which generates a sawtooth waveform 19 or a steeper waveform or a constant voltage, and a double pulse 23. Pulse shaper 24 generates an inhibitor pulse equal in duration to the positive-going part of pulse 23 and device 25 delays it by one line period after which it is fed to the deflection modulator. Pulse shaper 27 derives from the double pulse a single pulse 28 then delayed by a line period by device 29. The output pulses at terminals 30, 31 are used in known manner to ensure that only one pulse is counted for each particle scanned. A modification (see Fig. 4, not shown) uses one delay device only and a time-base generator with each sweep triggered from that device. The Specification describes with reference to Fig. 5 (not shown) parts of Fig. 3 and Fig. 4 (not shown) in more detail, particularly the deflection modulator. The field scanned may be a photograph of a particle field. Spiral scanning may be used.
