Title: Method of and apparatus for controlling the rate of flow of liquids through pipes orconduits
IPC: G05D7/01
Filed: 1950-09-04
Abstract: 698,420. Water supply systems. SIMPSON. J. H. Oct. 17, 1951 [Sept. 4, 1950], No. 21716/50. Class 68(i) To ensure a constant flow at a constant pressure from a conduit, the flow of liquid is throttled at a part upstream of its outlet in accordance with variation of the pressure of the liquid in the conduit between said part and the outlet. In one embodiment, upstream of the outlet is a manually operated regulating valve 2 and upstream of this the means responsive to the variation of pressure, said means being upright, the pipe 6, 9 open to atmospehere and having an elbow connected to a pipe 13 leading to a tank 14. The magnitude of the flow through this pipe is a measure of the pressure within the conduit 1. The tank has an outlet 15 of such a size that, when the conditions in the conduit are as desired, the inflow through pipe 13 is exactly balanced by the outflow through pipe 15. Increase in pressure in or greater flow through conduit 1 causes increased flow through pipe 13, a rise in the level of liquid in the tank and a partial closure of ball-valve regulated valve 16 until the desired conditions are again established. The valve 2 can be omitted. In a second embodiment, pipes 6, 9 and 13 are omitted, the tank being supplied from a valved-tube branched off the conduit and so arranged that, when the desired conditions exist, the tube projects a jet of liquid into a spout on the tank at a rate equal to the outflow of pipe 15. When conditions are below those required, the jet fails to reach the spout so that, as the ball valve sinks in the tank, the valve 16 is further opened.

Title: Improvements in or relating to the production of alkoxy crotonic esters
Inventor: CARROLL MICHAEL FRANCIS
IPC: C07C69/734
Filed: 1950-09-08
Abstract: Alkoxy crotonic esters, of general formula <FORM:0690573/IV (a)/1> in which R1 and R11 may be the same or different alkyl radicals, may be used as plasticizing components for plastic compositions such as cellulose nitrate and acetate, cellulose tri-propionate, acetobutyrate and tributyrate.ALSO:Alkoxy crotonic esters are produced by heating aceto acetic ester with an aliphatic primary alcohol or mixtures of such alcohols stable to acid catalysts in the presence of an acid esterification catalyst under such conditions that the water formed in the reaction is removed immediately it is formed.  The invention also comprises new compounds of the general formula <FORM:0690573/IV (b)/1> in which (a) R1 and R11 may be the same or different and are selected from the group n-butyl, n-amyl, n-hexyl, trimethyl hexamyl, lauryl, ethyl hexamyl and cetyl; (b) R1 and R11 are alkyl radicals derived from the mixture of alcohols obtained by reduction of the acids of a vegetable oil; and (c) R1 and R11 are alkyl radicals derived from a mixture of alcohols in the range C6 to C10 obtained by the OXO reaction of olefines.  Preferably the starting material for the production of the esters is methyl or ethyl acetoacetate and it is preferred to use excess alcohol.  The water may be removed as it is formed by azeotropic distillation. When higher alcohols are used a suitable azeotropic solvent is toluene, whereas for lower alcohols, except methanol, benzene is more suitable.  Superatmospheric pressure may be used if desired.  The acetoacetate may be formed in situ by the action of an alcohol on diketene.  It is advisable not to take the reaction to completion but to stop it when 50-90 per cent of the ester has been converted. Suitable acid esterification catalysts are sulphonic acids, sulphinic acid, phosphoric acids and aluminium chloride. In the examples: (a) hexyloxy-hexyl crotonate is prepared by the action of hexyl alcohol on ethyl acetoacetate; (b) ethoxy ethyl crotonate is prepared by the action of ethanol on ethyl acetoacetate; (c) lauroxy lauryl crotonate is prepared by the action of lauryl alcohol or acetoacetic ester; (d) diketene is reacted with butyl alcohol and the resulting mixture is heated to give the butoxy butyl ester; (e) methyl acetoacetate is heated with lauryl alcohol to give lauroxylauryl crotonate.

Title: Improvements in and relating to the stop motion of knitting machines
IPC: D04B35/10
Filed: 1944-11-11
Abstract: 619.488. Knitting-machines. BERRIDGE & CO., Ltd., I. L., MARTIN, C. S., COLTON, L. H., and COOKE, A. E. Nov. 11, 1944, No. 22254. [Class 74(ii)] A stop motion for preventing a press-off in the event of breakage or slackness of the thread includes a detector which operates at the end of the carrier transverse. The detector, which may travel with the carrier, may comprise a pivoted feeler 5, Fig. 3 that is swung towards a contact 9, at the end of each traverse by a timecontrolled electro-magnet 11 and is prevented from engaging the contact by a normally tensioned yarn. Alternatively, the feeler may be a depending spring 37, Fig. 8, which operates urder its own momentum at the end of the carrier traverse and is engaged, at its free end, by the running yarn. On the supply side of the feeler the yarn T passes between two trapper members 41, 42, which move one towards the other, to grip the yarn at the same time as the feeler operates. On failure of the yarn, the feeler 5 or 37 engages a contact 9 or 40 to complete an electric circuit to prevent a press-off. In a straight-bar machine prevention of the press-off is effected by the operation of a wind-up drum which releases the hand lever, so as to allow the needle bar to swing away from the presser under spring action. Specification 573,796 is referred to.

Title: Method of making porous bodies or materials
IPC: C04B38/06
Filed: 1934-07-31
Abstract: Porous bodies composed mainly of diatomaceous earth are made by shaping a mixture of diatomaecous earth, clay, water and a solid aromatic compound as pore-forming material, the diatomaceous earth being in major proportions, rmoving the pore-forming material, and firing.  The solid aromatic compound may be removed by volatilization, sublimation, melting or by solvent extraction. The preferred compounds are naphthalene and paradichlorobenzene. The diatomaceous earth may be one which naturally has a sufficient clay content to render it mouldable.  A non-volatile pore-forming ingredient which is burnt out during the firing of the mass, e.g. wood meal, sawdust, cork dust, may also be added.  In an example, a mixture of 95 parts of moler, 5 parts of crude naphthalene, 2 to 3 parts of sawdust and sufficient water is moulded and heated to a temperature below the melting point of naphthalene, to drive off the water and naphthalene.  The articles are then fired at a temperature of about 900 DEG  C.

Title: Improvements in and relating to methods of and means for feeding molten glass
IPC: C03B5/187
Filed: 1924-09-25
Abstract: 244,834. McNish, A., and Automatic Bottle Machine Corporation, Ltd. Sept. 25, 1924. Delivering molten metal.-A method of conveying molten glass from a tank furnace to a gathering point consists in providing a circuitous channel from the furnace to the gathering point and back again to the furnace, and in causing the glass to flow along this channel by means of an oscillating paddle. The channel is formed in a block 4 of refractory material which forms the floor of a forehearth attached to the furnace 3. The channel, as shown in plan in Fig. 2, comprises. a semi-circular portion B and two limbs A, C which connect the portion B to the body of the furnace, the limb C being tangential to the semicircular portion B. A weir or wall 8 is formed in the limb C and projects a short distance above the normal level of the glass. The paddle 9 for moving the glass is carried by an arm 11 extending from a central vertical shaft which is reciprocated vertically by an air cylinder 14, Fig. 1, and is oscillated through a semi-circle by another cylinder 19. By the combined movement the paddle is first dipped into the glass, is then moved through 180‹, and finally it is, raised out of the glass and returned to the dipping point, the movement being repeated at regular intervals. The glass is thus moved along the channel past the gathering point X and over the weir 8 to be returned to the furnace. If desired, the weir may be placed in the channel between the gathering point X and the paddle, and a number of weirs and paddles may be used. The paddle may be arranged to move in a straight line, and the depth to which it is submerged may be varied during the stroke. The weir may be dispensed with if desired.

Title: Improvements in the manufacture and production of cyclic hydrocarbons from gaseous acetylene hydrocarbons or aldehydes
IPC: C07C2/00
Filed: 1929-02-23
Abstract: 334,203. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 23, 1929. Divided on 334,193. Cyclic hydrocarbons are prepared by passing acetylene, or mixtures thereof with its homologues, over heated condensation catalysts, and then conducting the products, without isolation, together with hydrogen over metallic hydrogenating catalysts. Instead of acetylene, aliphatic aldehydes may be employed, or mixtures thereof with the acetylene hydrocarbons. The condencation catalysts comprise compounds of aluminium or of metals, except arsenic, having a. specific gravity above 4.4 and belonging to the second to the seventh periodic groups; hydrogenating catalysts mentioned are metals of the iron group, copper and platinum. The hydrogenating catalyst is arranged behind the condensation catalyst either in the same reaction chamber or in adjacent chambers. The hydrogen may, if desired, be introduced prior to the condensation stage. Industrial gas mixtures containing hydrogen and acetylenic hydrocarbons may be employed, e.g. coke-oven gas or gas mixtures obtained by passing coke-oven gas or a mixture of methane and hydrogen through a high tension electric arc. The condensation is usually effected at a temperature, of 250‹-500‹ C. and the, subsequent hydrogenation preferably at a lower temperature, e.g. 150‹-250‹ C. According to the Example, acetylene and hydrogen are passed over zinc chloride mounted on silica gel at 450‹ C., and then over finely-divided nickel at 200‹ C. The condensed product contains hydrogenated benzene. Specification 109,983 is referred to. The Provisional Specification states that any acetylene hydrocarbon may be employed.
