Patent GB-103838-A (GB)
Title: Improvements in and relating to Semi-automatic Compressed Air Brakes for Railway and Tramway Vehicles.
Inventor: NEGRINI GIOVANNI
IPC: B60T13/36
Filed: 1916-01-31
Abstract: 103,838. Negrini, G. Jan. 31, 1916. Fluid-pressure.-In a system particularly for a motor-vehicle with trailer, the auxiliary reservoir 2 on the motor-vehicle is directly connected to the through train pipe 6<1>, 9, 10, and the driver's valve 4 is adapted to connect this train-pipe with the brake cylinder 3 of the motor-vehicle, thereby applying the brakes on this vehicle, while the consequent reduction of pressure in the train-pipe effects the actuation of the triple valve 13 and the trailer brakes are simultaneously applied. The pressure on the motor-vehicle brakes may be increased by connecting the main reservoir 1 to the brake cylinder 3. The brakes may be separately released on the motor-vehicle and trailer. The driver's valve has the main-reservoir pipe 5<1> open to chamber 23, and the seat provided with ports 6, 7, 17 connected to pipes 6<1>, 7<1> and exhaust respectively, and the port 15 connected to pipe 7<1> through the check valve 16. The rotary member 18 of the valve is pierced at 20, 21 and has a cavity 22. Fig. 6 shows the release and charging position with the ports 20, 6 in register and the ports 7, 17 connected by cavity 22. In Fig. 7, the ports 6, 15 are shown connected for an ordinary application, and in Fig. 8, the port 21 is shown registering with the port 7 so as to connect the brake cylinder 3 with the main reservoir 1 as well as with the train-pipe 6'. To release the motor-vehicle brakes separately from the trailer brakes, the valve member 18 is moved to a position intermediate between that shown in Figs. 6 and 7 to connect the ports 7, 17 by the cavity 22 without registering the ports 6, 20. By moving the valve from an application position to a position close to that shown in Fig. 6 for a short time, it is possible to charge the reservoir 2 and train-pipe 6<1> sufficiently to release the trailer brakes without completely exhausting the brake cylinder 3 of the motor-vehicle. With the trailer uncoupled and the angle-cocks in closed position, the operation of the brakes on the motor-vehicle remains as described. If the train-pipe 6' and auxiliary reservoir 2 are exhausted by a break-in-two or otherwise, the brakes on the motor-vehicle can still be applied by mainreservoir air.

Patent GB-725421-A (GB)
Title: Adrenocorticotrophin preparation and process for producing same
Inventor: THOMPSON ROBERT EDWARD
IPC: A61K38/35
Filed: 1953-01-13
Abstract: Preparations suitable for parenteral administration comprise adrenocorticotrophic hormone substance, non-antigenic and if desired, partly hydrolysed gelatin suitably present as a 5-35 per cent aqueous solution, and optionally, retarding agents such as polyvinyl pyrrolidone and/or non-toxic difficultly water-soluble astringents, e.g. aluminium phosphate and hydroxide, magnesium phosphate.  In two examples frozen pituitary glands, ground and thawed, are extracted with aqueous acetone at pH 1.5, centrifuged, and acetone is thereupon added to the liquid to cause precipitation.  The powder obtained is extracted with disodium phosphate solution and centrifuged; the supernatant material is treated with ammonium sulphate and the precipitate formed is dialyzed to remove the ammonium salt.  The material is then optionally hydrolyzed with hydrochloric acid, and lyophilized.  It is thereupon reconstituted with distilled water and mixed with gelatin solution.  In a third example, acetone-dehydrated anterior hog pituitaries are extracted with glacial acetic acid, acetone and a small amount of salt to precipitate impurities are added, and crude adrenocorticotrophin precipitated with ethyl ether; this is purified by adsorption on oxycellulose, elution with hydrochloric acid solution and treatment of the eluate with an anion-exchange resin to convert the adrenocorticotrophin to the acetate.  The solution is thereafter admixed with gelatin solution. Other examples describe the preparation of solutions of adrenocorticotrophin, gelatin and an astringent starting from the hormone.
