Title: Improvements relating to the production of concentrated rubber latex and of rubber from rubber latex
IPC: C08C1/08
Filed: 1924-05-29
Abstract: 226,440. Traube, I. May 29, 1924. Latex, concentrating.-Latex is concentrated or solid rubber is separated from it by treatment with a vegetable or animal colloid substance such as carrageen or Iceland moss or gelatine. Concentration may be effected by adding 14 litres of water containing 140 grams of moss to 100 litres of latex and allowing the mixture to stand at 50- 60‹ C., whereupon it separates into two layers of which one contains all the rubber at twice the original concentration. Coherent layers of rubber may be obtained by pouring latex, either concentrated or not, upon a jelly or gelatin or other colloid to which dehydrating agents such as glycerin or molasses may have been added. If concentrated latex is used filling and vulcanizing agents may be added to it.

Patent GB-133109-A (GB)
IPC: F01B25/00
Abstract: 133,109. Gentile, N. July 2, 1918. Ship and boat waste products, dealing with.- Fresh water which has been used for cooling the machinery of a ship is freed from oil by decanta. tion and re-used. The water is collected in a tank, which it enters by hinged doors covered with wire-gauze 41, and from which it is drawn by a pump 1 through a pipe 2 terminating in a float 3 To prevent the mixture of water and oil from being drawn into the pump, the pipe 2 delivers into a pivoted tank 9, Fig. 7 from which the pump ex hausts the air. When the tank 9 is full, it tilts and discharges the water and oil through a hinged valve 16, air being admitted through a pipe 15 normally closed by a ruober washer 17 on a bracket 18. The oil is removed from the water in the separator shown in Fig. 9, which consists of a cylindrical vessel provided with a bent tube 23 through which the water escapes, having an opening at 24 and an oil outlet 26. The water is returned to the tank and is withdrawn therefrom for re-use through a pipe 36, the end of which is supported on a float so as to open below the layer of oil on the surface of the water, and is surrounded by a wire-gauge screen to prevent the ingress of dirt. The water passes through one of two filters 37, 38, Fig. 3, in openings in block 34 contained in a casing 40 and capable of adjustment by screws 39 so as to bring either filter opposite to the pipe 36. An overflow device is provided, which shows when the system is full of water.

Title: Automatic trailer brake and lock release system
IPC: B60T17/18
Filed: 1966-03-25
Abstract: 1,114,299. Fluid-pressure brakes; valves. BENDIX - WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. 25 March, 1966 [1 April, 1965], No. 13320/66. Headings F2F and F2V. In a trailer braking system including a trailer fluid pressure reservoir 12, fluid pressure operated brake actuators 16, spring-applied fluid pressure released braking locking mechanisms 18 for locking the trailer brakes in the applied position and including a fluid pressure lock release port 14 connected to the reservoir via conduits 42, 44, the locking mechanism is movable to an unlocking position when the pressure in the reservoir is above a predetermined level and a relay emergency valve 14 including a control port 20 between the actuators and the reservoir automatically controls the flow of fluid from the reservoir to the actuators and from the actuators to atmosphere depending on whether pressure at the control point is above or below a predetermined level. An emergency conduit is directly connected to the reservoir and branch fluid pressure conduit means 22 including control valve mechanism 26 connecting the control port of the relay valve 14 with the emergency conduit 10 such that the control valve mechanism includes a normally open exhaust valve formed by a piston valve 74 (Fig. 2) connecting the control port 20 to atmosphere via conduit 22. The control valve mechanism 26 includes a normally closed check valve 60 which disconnects the control port 20 from the emergency conduit 10 and a fluid responsive valve operating means is connected to the emergency conduit 10 and is responsive to a pressure in the conduit in excess of the unlocking pressure to close the exhaust valve 74 and to open the normally closed valve to deliver an increased emergency conduit pressure 10 to the control port 20 of the relay emergency valve 14 to effect release of the pressure from the actuator 16. A one-way check valve is provided in the emergency conduit between the reservoir 12 and the branch fluid pressure conduit means 22 to permit flow of fluid pressure towards the reservoir while preventing flow in the reverse direction. The presence of the valve 26 eliminates any possibility of a premature release of the brake actuators prior to the release of the locking mechanism 40 because of accidental charging of the emergency conduit means 22 via reverse leakage of fluid pressure from the reservoir past either the check valve 60 or the conventional charging check valve (not shown) in the relay emergency valve 14. Any leakage cannot build up in the emergency conduit means 22, but must flow directly to atmosphere through the open flow path between the exhaust port 30 and the delivery port 24 of the control valve mechanism 26.

Patent GB-1038003-A (GB)
Title: Preparation of esters
IPC: C07C67/26
Filed: 1964-04-01
Abstract: Esters are prepared by reacting a C2- 4 alkylene oxide with a saturated or unsaturated monocarboxylic acid or an ethylenically unsaturated monocarboxylic acid in the presence of an alkali metal halide or an alkaline earth metal halide.  The term "alkylene oxide" includes epichlorhydrin.  Suitable reaction temperatures lie in the range 50-150 DEG  C.  The preferred catalyst is LiCl.  The mono-basic acid may be an alkyl, aryl or alkenyl compound and may be substituted by carboalkoxy or carbohydroxyalkoxy groups.  If the acid contains a polymerizable group a phenolic or copper salt type polymerization inhibitor may be used. When preparing hydroxyalkyl methacrylates using a LiCl catalyst a particularly pure product, which does not polymerize on standing, is obtained by venting off unreacted alkylene oxide at the end of the reaction and adding oxalic, oxydiacetic, adipic acid or a mixture thereof, agitating the mixture and filtering to give a lithium free product.  The examples relate to the hydroxyalkyl esters of methacrylic, acrylic, acetic benzoic and maleic acids.  Reference has been directed by the Comptroller to Specification 956,412.
