Title: Fluid pressure regulator
IPC: G05D16/06
Filed: 1951-07-18
Abstract: 723,874. Valves. KROMSCHRODER AKT.- GES., G. July 18, 1951 [Aug. 4, 1950], No. 17059/51. Class 135. A fluid-pressure regulator comprises a hollow valve member floating freely on membranes without rigid guide means and movable relative to a valve plate, the membranes including a working membrane attached to the member between its ends and a compensating membrane above which the upper edge of the member protrudes. The Venturi-shaped tubular valve member q is supported by a working membrane f and a compensating membrane e, attached to a casing partition a<SP>1</SP>, carries a loading weight I at its lower end and seats on a universally tiltable plate b. A safety membrane g perforated at h provides a dash-pot chamber D between the other membranes open to the atmosphere via chamber E and opening p and prevents a large escape of gas should either of these membranes break. A rigid suction-producing diaphragm i carries a collar o whereby the flow of gas through the member q produces a high or low suction in the space B according to whether the lower end of the member is below or above the collar, corresponding to open or closed position of the member. The working parts of the regulator are formed in a middle casing section d so that various forms of inlet and outlet sections a, c may be used. The working membrane f is responsive to outlet pressure variations via the space B, while the compensating membrane e is acted upon by inlet pressure which is balanced by inlet pressure acting under the flange z at the top of the member. The reduced suction in the space B when the member q is raised is compensated for by the downward pull of the membrane e and the increased suction when the member q is lowered by the upward pull in the membrane e. In this way the regulator outlet pressure from zero up to maximum outflow is kept constant and independent of inlet pressure variations.

On the rebound, the resistance diminishes until the surface 7 becomes operative when it again increases. The position of the levers 1 may be reversed, the levers being pivoted to the axle. The movement of the lever 1 may alternatively be transmitted to a shock absorber through screws, toothed wheels, cams, or eccentrics, and may be used to control the exhaust ports of a fluid shock-absorber or to control compressed air or vacuum apparatus.
Patent GB-689591-A (GB)
Title: Improvements in or relating to carburetters for internal combustion engines
IPC: F02M7/20
Filed: 1950-07-11
Abstract: 689,591. Carburetters. ZARNACK, W. July 11, 1950 [July 13, 1949], No. 17368/50. Class 7 (iii). In a carburetter in which the mixture is formed at the throttling point 3 in the venturi 2 and, in which the fuel is sucked in by the vacuum formed at the point 3, it is arranged that the fuel flow is regulated by an automatic regulator such as needle valve 9, which is actuated by change in suction at a predetermined point in the venturi 2, for example where a conduit 17 joins the venturi in front of or behind the throttling point 3, to produce a corresponding change in the suction in a fuel metering nozzle 8 located between a float chamber 6 and the regulator and thereby set the latter in a position of equilibrium so that the quantities of air and fuel in the mixture are in the same proportion as the cross-sections of the venturi at the predetermined point and fuel nozzle 8. Fuel from the float chamber 6 flows through the metering nozzle 8 past valve 9 and into a conduit 10 that opens'into the venturi at the throttling point 3 by means of an atomizing nozzle 11; the atomization in nozzle 11 is improved by the admission of additional air into conduit 10 through a nozzle 15. A passage 16 opening into the fuel line downstream of the metering nozzle 8 conducts the negative pressure therefrom to the underside of a diaphragm in a chamber 19, the topside of the diaphragm being subjected to negative pressure from the venturi 2 conveyed through 'conduit 17. The valve 9 is operated by the diaphragm, and under light or no load conditions a spring 12 closes the valve 9 and fuel is conducted to a slow running jet 13 which may be controlled by a needle valve 14 conjointly operated with the throttle valve 4. In a modification, one float chamber and diaphragm assembly sup-. ply fuel to a number of spraying nozzles. In both embodiments a conduit opening into the top of the float chamber leads to the air intake on the upstream side of the conduit 17 to short circuit the positive pressure. The cross-section at the throttling point with fully open throttle is smaller than the cross-section of the venturi at the predetermined point so that the fall in pressure between these points is the same as or smaller than the pressure full between the fuel and atomizing nozzles.

The invention of Specification 849,971 is modified' by the provision of stop motion mechanism brought into operation on breakage or exhaustion of yarn and including a wedge shaped brake shoe 10 pivotally mounted adjacent the driving roller 11 in curved arms 12, a lever 14 pivoted at 143 and furnished at one end with a roller 142 adapted to bear against one arm 12 and at its other end with a balance weight 16 forming a starting handle, a lever 17 pivoted at 171 furnished at one end with a rotatably mounted guide pulley 18 and at its opposite end with a balance weight 19, a triangular plate 20 secured to lever 17 and providing an abutment for a roller 21 on handle 16, the balance weight 19 serving to hold the stop in contact with the roller to maintain the guide pulley in the winding position. Should the yarn break or fail through exhaustion of supply, the lever 17 rocks forward about its pivot due to the guide pulley 18 losing the support of the yarn Y. This movement takes the stop 201 away from the roller 21 on the lever 14 which then falls due to the weight 16 and, rocking about its pivot 143, causes the roller 142 to press against the arm 12 and push the brake shoe 10 upwards to force the package 'P' out of contact with the driving roller 11 and stop the winding.

Title: Improvements in or relating to the preparation of aliphatic, aromatic, and cycloaliphatic esters of carboxydicyandiamides and salts thereof
IPC: C07C279/28
Filed: 1943-10-27
Abstract: Alkyl, aryl or cycloalkyl esters of carboxydicyandiamides or salts thereof are prepared by mixing dicyandiamide, an alkyl, aryl or cycloalkyl chlorocarbonate and a water soluble alkali metal, or alkaline earth metal oxide or hydroxide, and allowing the mixture to react in the presence of water at a temperature not exceeding 75 DEG C.  Specified oxides or hydroxides which may be used are those of sodium, potassium or lithium.  The reaction may be carried out in the presence of a solvent, preferably nonhydroxylated, such as acetone, pyridine, dioxane, ether or benzene.  The free acidic form of the product may be precipitated from the strongly alkaline reaction mixture by the addition of an acid such as acetic, propionic, sulphuric, hydrochloric, sulphurous or phosphoric acids.  The free acid can be used to prepare other salts by treating with basic materials such as ammonium hydroxide, methylamine, ethylamine, diethylamine, butylamine, 2 - ethylhexylamine, dodecylamine, aniline, methylaniline, a -naphthylamine, pyridine, 2-aminopyridine, morpholine, guanidine, biguanide, phenylbiguanide, diethylbiguanide, acetamidine, benzamidine or caproamidine. Examples of chlorocarbonates which may be used are methyl, propyl, iso-propyl, n-butyl, iso-butyl, octyl, dodecyl, tetradecyl, octadecyl, diamyl phenyl, cresyl, xylyl, b -ethoxyethyl, g -ethoxypropyl, b -ethoxyisopropyl, b -propoxyethyl, g  - propoxypropyl, b  - butoxyethyl, g -butoxypropyl, b -phenoxyethyl, b -phenoxyisopropyl, g -phenoxypropyl, o -phenoxy-n-hexyl, b -cyclohexoxyethyl, b -ethylphenoxyethyl,, g -ethylphenoxypropyl, b  - butylphenoxyethyl, diamylphenoxyethyl, diethoxyethyl, propoxyethoxyethyl, dipropoxyethyl, propoxypropyl, g -acetoxypropyl, b -acetoxyethyl, g -lauryloxypropyl, b -stearyloxyisopropyl, p - N - myristyl - aminophenyl, n - N - benzoylaminophenyl, N - stearamidoethyl, N-lauramidoethyl and N-stearamidopropyl chlorocarbonate. Ethylenedichlorocarbonate, tetramethylenedichlorocarbonate and the dichlorocarbonate of diethylene glycol may also be used.  In the examples, carbethoxydicyandiamide, carb-2-ethylhexoxy-dicyandiamide, carbobenzyloxydicyandiamide, carbocyclohexoxydicyandiamide, b  - N - ethyl - lauramidocarbethoxydicyandiamide and carbophenoxydicyandiamide are prepared from dicyandiamide and the appropriate chlorocarbonate in the presence of alkali and water.  In each case, the reaction mixture is acidified with acetic acid to precipitate the product.  The compounds may be used as intermediates in the preparation of organic compounds such as guanylureas and ammelides and of azo dyes, resins and pharmaceuticals.  Some have useful cationic surface active properties and others may be employed alone or with compounds such as methylated methylolmelamine for producing textile finishes imparting water-proofing, crease-proofing and anti-shrink properties.
