Title: Improvements in fluid flow control valves
IPC: F16K31/02
Filed: 1961-03-03
Abstract: 914,218. Valves. ALLMANNA SVENSKA ELEKTRISKA A.B. March 3, 1961 [March 5, 1960], No. 7787/61. Class 135. A valve having a sealing position when open, as well as when closed, has a spindle 5 driven by a motor 1 through a clutch with electromagnetically coupled parts 2a, 2b and gearing 3, 8 with a speed-sensing device 6 which switches the motor off when the valve reaches its sealing positions, the slipping torque of the clutch being adjustable to different values by the use of switched resistors in its supply circuit. When the valve has to be opened a push-button is pressed to energize a contactor in the motor supply circuit and to close a holding circuit incorporating the device 6. Current from a D.C. supply flows through a line 17 and a portion of a resistor 16 to the winding 15 of the clutch until a switch 11<SP>111</SP> opens automatically after a predetermined delay when the current flows through a line 19 and a larger resistor 16 to reduce the slipping torque in readiness for sealing of the valve in its open position where the motor is stopped by the device 6. When the valve has to be opened, a second contactor in a circuit similar to that containing the first changes the phase sequence of the motor supply, opens a contact 12<SP>111</SP> and closes a contact 12<SP>1111</SP> so that a resistor of intermediate value is incorporated in the supply to the clutch and the sealing torque for the closed position is the same as the loosening torque for the open position. The circuit may, however, be modified so that the latter is smaller than the former. The valve may be operated by a hand wheel 7 held in disengaged position by a device 9 which also prevents motor operation when the hand wheel is in use.

Filed: 1920-03-18
Abstract: 165,179. Cope, H. A., (Cloud, J. W.). March 18, 1920. Fluid - pressure. - In valve mechanism for use with triple valves of usual form to permit graduated release of the brakes, one element of the brake cylinder exhaust valve is adapted to be displaced to an extent dependent upon the increase of train-pipe pressure, and the position of the co-operating element of the valve is dependent upon the brake cylinder pressure. The piston 5 is subject to the opposing action of a spring 6 and of the brake cylinder pressure admitted by the port 3 and the exhaust port of the triple valve when this valve is in the release position. The piston 5 forms the seating of a valve member 7 against which abuts the stem 16 of a piston 10 subject to the opposing action of a spring 12 and of the train-pipe pressure admitted at 2. Assuming the pistons to be in equilibrium so that the valve 7 is seated, upon raising the train-pipe pressure by a certain amount, the valve 7 is raised by the piston 10 and air from the brake cylinder exhausts through the port 9 until the brake cylinder pressure has reduced an amount sufficient to permit the spring 6 to move the piston 5 into a position in which the valve is again seated. A port 13 connects the spring chamber of the piston 10 to atmospheres.

Title: Process for the manufacture of bicyclic sulphur compounds
IPC: C07D495/04
Filed: 1944-05-01
Abstract: Bicyclic sulphur compounds are obtained by treating thioethers of 5-mercaptomethylhydantoin of the general formula <FORM:0576489/IV/1> wherein R represents an organic radical containing and attached to the adjacent methylene group by a carbonyl group, or it represents a cyano radical or an alkenyl radical, having a double bond adjacent to the methylene group, with condensing agents facilitating the splitting off of water, e.g. sulphuric acid or phosphorus oxychloride.  In the examples, bicyclic sulphur compounds are prepared from the carboxymethyl thioether and from the 5-carboxypentanone (2) thioether of 5-mercaptomethylhydantoin, the product from the latter compound having a lactone ring in the side chain.  Thioethers of 5-mercaptomethylhydantoin of the above general formula are made by etherifying b -mercapto-a -amino- or -ureido-propionic acid with o -halogen compounds, if necessary converting the amino group into the ureido group, and then closing the ring between the ureido group and the carboxyl group. The carboxymethyl thioether is made by condensing b -mercapto-a -amino-propionic acid with ethyl chloracetate, converting the product to the a -ureido compound by means of potassium cyanate and closing the ring by treatment with hydrochloric acid.  The 5-carboxypentanone (2) thioether is made by condensing b -mercapto-a -amino-propionic acid with methyl o -bromo-d -keto-caproate (made by decomposing with hydrobromic acid the diazo compound formed by reacting diazomethane with monomethyl glutarate) and converting to the ureido and to the hydantoin derivative as above.  The Specification as open to inspection under Sect. 91 comprises also the use as starting materials of compounds of the above formula, wherein R represents any organic radical which activates the adjacent methylene group.  In the example describing the production of the compound having a lactone ring in the side chain, a second fraction is obtained which has a keto-carboxylic acid group in place of the lactone ring.  This subject-matter does not appear in the Specification as accepted.
