Title: Improvements in and relating to combined radio transmitting and receiving equipment
IPC: H04B7/155
Filed: 1947-01-24
Abstract: 630,897. Radio receiving apparatus; directive radio systems. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. Jan. 24, 1947, No. 2272. [Classes 40 (v) and 40 (vii)] To cancel the effect of unwanted coupling between the transmitting and receiving portions of a combined transmitter-receiver equipment a passive reflector is provided reflecting energy from the transmitting aerial to the receiving aerial in such phase and amplitude as to cancel the effect of the coupling. In a two-way repeater station as shown, unwanted coupling between transmitting aerial A1<1> and receiving aerial A2 is counterbalanced by means of a reflector B directing an equal and oppositely phased signal from All to A2. Reflector C similarly balances the unwanted coupling between A2<1> and A1. The reflectors B and C may be of sheet metal and adjustable as to their distance from the aerials. The amplitude of the reflected energy may be altered by changing the size of the reflectors or, preferably, by rotating them so that their inclinations to the energy paths and thus their effective area is varied. The whole antenna system including the reflectors may conveniently be supported on a common structure.

Filed: 1916-02-23
Abstract: 102,411. Eustis, F. A., Perin, C. P., and Moa Bay Iron Co. Feb. 23, 1916. Alloys; treating ores to remove undesired constituents; sulphatizing.-A process for treating ores containing a number of metals capable of reduction together to yield an alloyed product comprises dividing the ore into predetermined quantitative parts, one of which is subjected to treatment to separate therefrom a product containing a compound of one of the metals, such product being then mixed with a part of the ore not so treated, so that there are obtained a product of ore enriched as to its contents of one metal, and a product of ore improved by the removal of one or more metals. For example, an ore containing iron, chromium, manganese, and nickel may be divided, and one part sulphated, either by moistening with sulphuric acid and roasting at about 500‹ C. for two hours or more, or by the addition of 5 to 10 per cent. of sulphur-bearing material, such as pyrites, and roasting at about 460‹ C. for about 4 hours. The nickel sulphate and other soluble salts are leached out, preferably with dilute acid, and the solution is evaporated or precipitated and the product added to another part of the ore; or the evaporation or precipitation may be effected in contact with the part of the ore to be enriched.

Abstract: 857,550. Coated tablets. LOWEY, H. Jan. 25, 1957 [Jan. 25, 1956; July 19, 1956], No. 2762/57. Class 81(1) A plurality of substantially round medically inactive granules to each of which has been applied an impregnating layer of a medically active substance in ethyl cellulose is coated with a plurality of structurally independent ethyl cellulose coatings comprising an actiondelaying layer or layers, the or each said layer containing a total amount of ethyl cellulose not exceeding two per cent of the weight of the inactive granules substantially equally divided among said coatings and each independent coating being not substantially thicker than one tenth of one per cent of the radius of the uncoated granule. As shown (Fig. 2) a granular carrier. 1 of sugar or com starch is impregnated with a solution of say nitroglycerine or aspirin in ethyl cellulose, preferably applied in a plurality (say 12) operations. This forms a medically active layer 2 partly percolating into and partly around the granule. The action delaying layers 3, 4, 5 each comprise 25 independent coatings, each coating being formed from the same weight of ethyl cellulose coating solution. This solution contains a high proportion of solvent (alcohol) and a few per cent of beeswax and castor oil to increase the plasticity and elasticity of the coating: the amount of ethyl cellulose is 15 % by weight of the solution. The coating operation may be carried out in a conventional pan rotating at a much higher speed than usual. Between each coating and after drying the granule carrying the still soft coating is dusted with very fine talc. Using 1 lb. of ethyl cellulose solution per coating and 200 lbs. of inactive granules carrying a medically active impregnating layer it is found that 25 independent coatings form an action delaying layer of 1 hour duration. Thus by forming granules containing different multiples of 25 coatings into a tablet it is possible to control the release of the medicament and to sustain its release over a predetermined time. The coated granules may be tableted with inactive filler granules.

IPC: B61H9/00
Filed: 1917-02-27
Abstract: 105,225. Turner, W. V. March 31, 1916, [Convention date]. Fluid-pressure.-Application of the fluid-pressure brakes on a locomotive is prevented, when the regenerative brake is in operation, by an electromagnetically-controlled valve in the regenerativebrake circuit adapted to cut off communication between the pressure-fluid reservoir and the distribution valve. The distribution valve 1 shown comprises a piston 3 operating valves 4, 5 respectively controlling admission and release of the pressure fluid to and from the brake cylinder. A passage 6 leads from the piston chamber 2 to the pipe 7 connected to the brake valve. The main reservoir is connected by pipe 13 to the valve chamber 11, into which normally opens also the pipe 20 connected to the distribution-valve chamber 19. A piston slide valve 10, 12 works in the chamber 11, and the fluid pressure on the two sides of the piston is normally equalized by the port 15. When, by the energization of the magnet 17 in the regenerative-brake circuit, the valve 16 is actuated to seat the piston chamber 9, the valve 12 is moved to close the pipe 20 to the valve chamber 11 and open it to the exhaust port 22, thereby preventing application of the fluid-pressure brakes. At the same time, a connexion 71 from the pipe 7 is also connected to the exhaust port 22, so that should the fluid-pressure brakes be already applied, they are released by the application of the regenerative brake.
