Title: Improvements in or relating to air pressure brakes
IPC: B60T15/50
Filed: 1928-09-26
Abstract: 297,753. Knorr-Bremse Akt.-Ges., (Assignees of Drolshammer, I.). Sept. 26, 1927, [Convention date]. Fluid-pressure. - In valve mechanism for air pressure brakes of the kind in which the valve operating piston is controlled by the pressure in the train-pipe and also that in a chamber which is connected to the train-pipe in the full release position of the valve, the chamber is arranged to be connected with the auxiliary reservoir in the release position so as to prevent the chamber from being overcharged. A valve of the Drolshammer type described in Specification 264,197 is shown, the upper chamber of the piston 1 of which is permanently connected to the trainpipe and the lower chamber to a chamber A. In the full release position of the piston 1 the chamber A is connected to the upper valve chamber and thus to the train-pipe by a passage 37 which, however, is closed by the initial movement of the piston in applying the brake. To enable the train-pipe pressure to be temporarily raised above the normal to effect a rapid release of the brake without overcharging the valve chamber A. The auxiliary reservoir B is connected to this chamber by means of a passage 121 which is uncovered in the full release position of the piston 1 by a small piston 120 connected to the piston 1, thereby increasing the effective capacity of the lower piston chamber. The normal filling of the auxiliary reservoir is effected through a separate passage provided with a non-return valve as described in Specification 219,331. The passage 121 may be so arranged as to be opened when releasing the brake, before the pressure existing previously to the operation of the brakes is reached so that the valve piston moves to its lowest position and the brake is fully released with a pressure somewhat below the normal pressure. The opening 121 can also be so arranged that it may be closed before the passage 37 or a non-return 123 may be disposed in the connection of the reservoir B to the passage 121 so that the passage 37 may be as small as possible having regard to the sensitiveness of the valve.

Title: Control valve for pneumatic equipment
IPC: F15B13/04
Filed: 1961-07-31
Abstract: 989,225. Valves. D. HAUBOLD. July 31, 1961 [July 29, 1960], No. 27749/61. Heading F2V. The supply and exhaust of air to and from the operating piston of a machine e.g. a stapler, is controlled by venting the chamber beneath the piston 51, Fig. 2, of a valve 47 upon lifting an operating lever so unseating an auxiliary valve 68 and preventing further admission of air thereto from the supply passage 48 by urging the upper end of the rod 45 on to a seat 64. The pressure in the supply passage 48 is then enabled to open the valve 47 and admit air to the working port 65; subsequently the valve 47 closes the exhaust passage 67. -Upon releasing the operating lever the rod 45 falls to the position shown so that supply pressure acts on the piston 51 to seat the valve 47 and open the port 65 to the exhaust passage 67. The main valve may be formed as a lift closure by an " 0 "-ring in a groove on the main valve stem whilst the auxiliary vent valve has plane sealing surfaces. In a modification, a pin 103, Fig. 4, is elevated either directly or by the operating lever to unseat a spring-loaded ball-valve 93 and allow air from the supply passage 81 to enter a chamber beneath the piston 84 of the main lift valve 77 so opening the passage 81 to the working port 105 and causing the piston 84 to block the exhaust passage 106. Upon releasing the pin 103 the ball valve 93 is spring closed and the supply pressure closes the main valve 77.

Title: Preparation and use of grignard reagents
IPC: C07C51/15
Filed: 1962-07-19
Abstract: Grignard reagents of formula R-C2H4-MgX are made by reacting in a Grignard solvent medium an olefine of formula R-CH=CH2 with an alkyl Grignard reagent of formula R1-MgX in the presence of a halide, alkoxide or aryloxide of titanium or zirconium, where R is a monovalent radical free of substituents reactive to said alkyl Grignard reagent, R1 is an alkyl radical having at least 2 carbon atoms and having at least one hydrogen atom on the b -carbon atom, and X is a halogen.  The expression "Grignard solvent medium" includes the dialkyl ethers, cyclic ethers e.g. dioxane and tetrahydrofuran, alkyl aryl ethers e.g. anisole and phenetole, dimethyl and dibutyl ethers of ethylene glycol, the diethyl ether of diethylene glycol and pyridine. The titanium and zirconium catalysts include the oxyhalides and halides in which organic radicals are directly attached to the titanium and zirconium atoms e.g. dicyclopentadienyl titanium dichloride, "Alkoxides" and "aryloxides" include compounds containing organic groups attached directly to the metal atom such as diphenyl titanium diisopropoxide, and monomeric and polymeric titanates and zirconates. The process is carried out by preparing the alkyl Grignard compound conventionally in the selected solvent, adding the olefin, cooling to below room temperature, adding the catalyst and allowing the temperature to rise, if necessary to 200 DEG C. by applied heating.  The Grignard compounds so prepared may be used to prepare other compounds by reaction with carbon dioxide, aldehydes, ketones, water, organic orthoformates &c.
