Abstract: 713,769. Aerials. GENERAL ELECTRIC CO., Ltd., and CORNBLEET, S. Sept. 25, 1952 [Sept. 28, 1951], No. 22757/51. Class 40 (7) In a reverse-feed aerial system comprising a parabolic reflector 2 and a length of tapered rectangular waveguide 1 projecting through the reflector from behind and terminating in a feed reversal box 4 located at the focus of the reflector, the box 4, as shown in horizontal cross section in Fig, 2 (i.e. the E plane of waveguide 1), comprises a waveguide ring 10 of circumference 3#g/2 and two short lengths of waveguide 12 and 13 coupled to the ring at points spaced #g/4 in opposite directions from the end of waveguide 1, the longitudinal axes of waveguides 12 and 13 at their junction ends being inclined at 60 degrees to that of waveguide 1 and the free ends of waveguides 12 and 13 forming apertures 5 directed towards the reflector. Shallow steps 17 on the outer surface of waveguide 1 reduce the width of the apertures and also introduce a mismatch which is partially compensated by adjustable polythene plugs 16 which also serve to reduce the separation of the E-plane phase centres in waveguide 1. As shown in vertical cross section in Fig. 3, the inner surfaces of the upper and lower walls 18 of the aperture ends of waveguides 12, 13 are flared at 19 at an angle of 19 degrees which also tends to make the E and H plane phase centres coincident but produces distortion of the beam in the H plane which is partially compensated by flanges 20 extending beyond the ends 21 of the side walls. Full dimensions are given for an operating wavelength of 3.2 cms. The waveguides 1, 10, 12 and 13 may be replaced by corresponding sections ot coaxial feeder. In a modification described in the Provisional Specification, the feed reversal box 4 comprises a rectangular metal box of the same height as the feeder waveguide 1 and three times the width and having an internal vertical cylindrical metal pillar. The feeder guide 1 is coupled to the open face of the box facing the reflector and the two sides of the box are extended towards the reflector to form two short radiating guides which may be filled with dielectric. Matching may be effected by filling the corners of the box remote from the open face with dielectric and by flaring the ends of the feeder guide 1 and the two radiating guides.

Title: Improvements in the production and recovery of isoparaffins, more particularly isopentanes
Filed: 1944-11-17
Abstract: A debutanized straight-run distillate from crude petroleum is fractionated to separate isoparaffins from residual normal hydrocarbons which are then thermally reformed and the product fractionated to recover a pressure distillate, C1-C4 hydrocarbons, and a residue fraction, said pressure distillate being fractionated to recover a C5 fraction containing pentane, isopentane and olefins, alkylating isobutane with the said fraction in the presence of sulphuric acid, fractionating to obtain an isobutane fraction, a C5 fraction and an alkylate fraction, and fractionating the C5 fraction to recover isopentane.  During the alkylation of isobutane with the olefinic C5 fraction using sulphuric acid as catalyst, for example as described in Specification 479,345, it is found that isopentane is produced.  In an example, a petroleum distillate of B.R. 25-125 DEG C. is superfractionated to recover isopentane, isohexane and isoheptane fractions, the residue being reformed, a C5 fraction separated, alkylated with isobutane in liquid phase using 85 per cent sulphuric acid at 10 DEG  C., and a separated pentane fraction superfractionated to recover isopentane while n-pentane is recycled to the reforming stage.

Title: Preparation of tetra-substituted diphenoquinones
Filed: 1962-06-14
Abstract: 3,31,5,51 - Tetrasubstituted diphenoquinones are prepared by reacting one or more 2,6-disubstituted phenols with oxygen or a gas containing free oxygen in the presence of a catalyst comprising a cyano-substituted hydrocarbon or tertiary-carbamoyl substituted hydrocarbon and a cuprous salt capable of existing in the cupric state and forming with such substituted hydrocarbon a complex soluble in the reaction medium, the substituents on the 2,6-disubstituted phenol being alkyl, cycloalkyl, alkoxy, aryl, haloaryl, aralkyl, alkaryl or aryloxy radicals. Lists of suitable phenols, cuprous salts and cyano- and tertiary carbamyl-substituted hydrocarbons are given. In addition to the nitrile or amide, which may serve as the solvent, another solvent, e.g. an alcohol, ketone, hydrocarbon, chlorohydrocarbon, nitrohydrocarbon, ether, ester, amide, mixed ether-ester or sulphoxide, may be present in the reaction mixture provided that it does not interfere with, or enter into, the oxidation reaction. Water formed during the reaction may be removed from the reaction medium by sweeping the same with an inert gas, by carrying out the reaction at a subatmospheric pressure, by azeotropic distillation, by the use of an open reaction vessel and/or by heating.  The reaction may be terminated by destroying the catalyst by the addition of an acid, e.g. hydrochloric or sulphuric acid, which reacts with the cyanide, amide or cuprous salt.

Title: Improvements in or relating to the electrical deposition of organic materials
IPC: C25D13/20
Filed: 1926-09-17
Abstract: 268,717. Kodak, Ltd., (Assignees of Sheppard, S. E., and Beal, C. L.). April 1, 1926, [Convention date]. Indiarubber, preparation of.-Bodies of porous non-conducting material are coated with rubber by electrolytic deposition from an aqueous emulsion, the bodies being inserted in the path of the current and adjacent the anode; the bodies are previously impregnated with a coagulating size in order to control the depth and character of the deposit. The size preferably consists of an hydrophilous colloid such as glue starch or dextrine acidified by acetic, formic. oxalic, lactic or other acid to a p<H> value between 3 and 7. For a heavy proofing on thin fabrics suitable sizes are a 10-15 per cent starch solution at 160‹-180‹ F., or a 5-10 per cent glue solution, or a 0.5-1 per cent solution of agar-agar. For a light proofing on one side of a fabric, a viscous size having a p<H> value 4-5 is used. If a deposit extending right through the fabrics and on both sides is desired, an almost neutral size having a p<H> value 5-7 is employed and is applied to the back only of the fabric. A very light deposit which covers all the threads but does not hide the weave of a fabric may be obtained by coating it on the back, before electrodeposition, with a solution containing 0.1- 0.3 per cent of agar-agar and 0.2 per cent of acetic acid. 0.3-0.5 per cent of sodium sulphite may be added. Sizes may also contain acid salts, highly ionized neutral salts or alcohol. In the apparatus shown, the fabric is passed from a drum 1 over rollers 3 through a degreasing tank 2, washing tanks 5, 6, and the sizing tank 9, being squeezed between rollers 4 after leaving each tank. It then passes under a metallic roller 13 constituting the anode of the depositing tank. The degreasing bath may consist of a solution of sodium carbonate, trisodium phosphate or sodium bisulphate; a 5 per cent solution of sodium sulphite is particularly effective. The depositing emulsion may be of the kind described in Specification 251,271. Sulphur, accelerators and pigments may be deposited along with rubber.
