Title: Process for making oil soluble artificial resins
Filed: 1934-06-20
Abstract: Synthetic resins are prepared by heating an aqueous solution of a -a -g -g -tetramethylbutylphenol containing at least an equivalent amount of an alkali metal hydroxide with formaldehyde, acidifying the condensate in the presence of a water-soluble oxalate or oxalic acid and a volatile, inert, water immiscible organic solvent for the resin, separating the resin, freeing it from acid and heating the product at a dehydrating temperature to eliminate the solvent.  4 : 4<1> - dihydroxy - diphenyldimethylmethane may also be added to the condensation to yield products with siccative properties.  The products are soluble in aliphatic, aromatic and hydroaromatic hydrocarbons and in animal or vegetable oils and fats.  In examples: (1) a -a -g -g -tetramethylbutylphenol is dissolved in aqueous caustic soda containing oxalic acid, heated with formaldehyde, the product acidified with sulphuric acid in the presence of ethylene dichloride benzene or toluene, the solution of resin removed and the resin recovered from solution and heated to yield a product soluble in benzene, petroleum naphtha, ligroin or linseed oil; (2) a mixture of a -a -g -g -tetramethylbutylphenol and p - p<1> - dihydroxydiphenyldimethylmethane is condensed with formaldehyde in a manner similar to that adopted in example 1.  Specification 409,111 is referred to.  The Specification as open to inspection under Sect. 91 refers in general to the condensation of a -a -g -g -tetramethylbutylphenol with formaldehyde.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to modulators for multi-channel signalling systems
IPC: H01J31/02
Filed: 1947-07-11
Abstract: 646,792. Thermionic distributers. GENERAL ELECTRIC CO., Ltd., and LEVY, M. M. July 11, 1947, No. 18483. [Class 40 (iii)] [Also in Groups XL (a) and XL (c)] A modulator for a multi-channel signalling system, and suitable for use in producing time or phase modulation of recurrent pulses in systems in which the pulses of one channel are interleaved with the pulses of one or more other channels, comprises a cathode-ray tube in which the beam rotates in a circular path over radial apertures 17 in a target 16, and in which two modulator electrodes 13, 14 are associated with each aperture for deflecting the beam tangentially with respect to the circular path. In a modification the apertured target 16 is replaced by a member made up of radial arms. A further target comprising buckets 18 mounted on an insulating plate 19 is arranged behind the apertured member 16 or the member with radial arms, and the output can be taken from either target. Either of the targets may be secondary emissive. An apertured mask 20 prevents the beam from impinging on the modulating electrodes 11, 13 ; 12, 14, which are carried on a central tube 10. Alternatively or in addition the beam may be modulated by oscillations of rectangular wave-form to switch the beam on and off at the correct times. The deflecting electrodes may be parallel to one another in transverse planes over a considerable part of their length, at least over a region extending on both sides of the circular path, and other parts nearer to and/or further from the axis of tube 10 may be approximately radial ; alternatively the electrodes may diverge slightly from tube 10 so that electrons of different velocities and consequently which are deflected to different extents by the means causing the beam to rotate may be equally deflected tangentially. The shape of the electrodes may also be modified to compensate for distortion of the electron optical system and for reasons of mechanical design. The deflecting electrodes may diverge along their length or alternatively they may be parallel or approximately parallel nearer the beam source and may diverge further from the source. In the latter case the cross-section of the beam can be made small compared with the distance between the deflecting electrodes to prevent distortion of the beam cross-section, and the deflecting electrodes are placed as close as possible to the electron source to get high sensitivity. The radial apertures 17 may have end portions which are inclined to the radial and preferably parallel to one another and the deflecting electrodes may have alternately outer and inner projecting flanges, Fig. 3 (not shown), so that even with excessive modulation the beam does not fail to traverse the apertures. When the radial arms are used they may be shaped in a corresponding manner. The Provisional Specification suggests in addition that the deflecting electrodes may be flared at the end adjacent the beam source as well as at the end remote from the beam source.

Title: Improvements in fertilisers
IPC: C05D9/00
Filed: 1933-07-03
Abstract: A fertilizer consists of a mixture of small pieces of coke of different sizes between 1/20 th inch size and 1/4 inch size containing the same or different soluble fertilizing substances.  The soluble fertilizers referred to are ammonium nitrate, phosphate and sulphate, sodium nitrate and potassium chloride.  The pieces of coke containing the fertilizers may be provided with protective coatings such as a mechanical protective or a film of a substance of low solubility.  Examples of such coatings are dry fine clay and/or very fine coke dust or dust of manurial value.  The fertilizer may be prepared by causing the small pieces of coke to absorb one or more soluble fertilizing substances from a solution or melt, the pieces preferably being pretreated to remove air, for example by the action of steam or a gas, such as ammonia and carbon dioxide, capable of condensation or solution in liquid containing the soluble fertilizing substance.  Alternatively, larger pieces of coke may be treated for the removal of air and impregnated with the fertilizing substances, the larger pieces being subsequently ground to the requisite size. When employing ammonium nitrate as the fertilizing substance, ignition of the coke is avoided by employing the ammonium nitrate as an aqueous solution at a temperature below 100 DEG  C. in the absorption step.  Specifications 192,778 and 253,291, [both in Class 111], are referred to.  The Provisional Specifications describe also the employment of pieces of other porous substances instead of coke having sizes which are not restricted to the limits set out above.

IPC: H01J41/18
Filed: 1953-07-10
Abstract: 762,365. Discharge apparatus. EDWARDS & CO. (LONDON), Ltd., W. Oct. 8, 1954 [July 10, 1953], No. 19260/53. Class 39(1). In an ionization vacuum pump the ionization of the gas to be evacuated is effected by means of a high frequency discharge. The pump shown comprises a cylindrical discharge chamber 1 of glass or other dielectric material having good secondary emission properties connected to a metal vessel 2 which it is required to evacuate. The vessel 2 is provided with an earth connection 3. A collector electrode 5 having a lead 6 for connection to a source of high voltage is supported in a continuation 4 of the chamber 1 of reduced diameter which is connected to a backing pump (not shown). A coil 7 surrounding the discharge chamber 1 is connected to a high frequency oscillator 8. An additional steady transverse magnetic field may be supplied to increase the lengths of the paths traversed by the electrons. The coil 7 may be replaced by two coils, each embracing one half of the periphery of the chamber 1, or by two plate electrodes either inside or outside the chamber. The discharge can be started with a potential as low as 100 volts, the required large increase in the number of electrons being obtained by secondary emission from the walls of the discharge chamber. The ionized gas particles resulting from collision are attracted towards the electrode 5 thereby forming a stream of gas which passes to the backing pump.
