Title: Improvements in or relating to rotary valves for internal combustion engines
IPC: F01L7/02
Filed: 1929-02-09
Abstract: 321,890. Aase, I. Feb. 9, 1929. Valves.-A valve 2 rotating within a stationary sleeve 3 is formed with a flange 8 engaging over the inner end of the sleeve, so when the valve is withdrawn axially, the sleeve is also removed. The sleeve is formed with a flanged outer end 5, which is bolted to the cylinder head or other part. In a modification, the valve and sleeve are formed tapering, and are maintained in tight ngagement under varying temperatures by a compensating-ring, which is inserted between the end of the sleeve and the flange on the valve and designed to give, by its expansion under heat, the required axial movement to take up slack caused by the different coefficients of expansion of the valve and sleeve. A spring or a second compensating-ring acts in opposition to the first; or a single ring may be arranged to act in both axial directions.

Abstract: 1,089,756. Semi-trailer couplings for motorvehicles. JOST-WERKE G.m.b.H. Feb. 4, 1965, No. 4997/65. Heading B7T. A semi-trailer coupling for motor vehicles with automatic compensation for wear, comprises a coupling plate 1 having a slot 2 receiving a king pin 6, and one (or more) locking plate 3 pivotable in a retainer 4 suspended from the coupling plate 1 and formed with a bearing recess 5 in which the king pin 6 is engageable and a locking recess 7 which is engaged by a spring-loaded locking element when the coupling is locked, which locking element causing rotation of the locking plate 3 to engage the bearing recess 5 with the king pin 6, and for maintaining this engagement so as to take up wear occurring between the king pin 6, the slot 2 and the bearing recess 5. In one embodiment, Figs. 1-5 (only Fig. 1 shown), the locking element is the end of a locking lever 8 which is guided by a portion 10 thereof movable in a cam guide 11, which is acted on by a helical tension spring 17 anchored at 16 to the plate 1, and which has a handle element 21 spring- biased into engagement with teeth 22. Any play at the king pin 6 due to wear is taken up by movement of the lever 8 and the plate 3. To unlock the coupling, the lever 8 is manually actuated in the direction of the arrow, the guide portion 10 then bearing against the second portion 13 of the guide 11 so that the free end of the lever 8 is withdrawn from the recess 7 and is retained by the engagement of a projection 14 thereon with an element 15 on the retainer 4. The plate 3 then rotates anticlockwise under the tension of another helical tension spring 24 until the king pin 6 is released from the slot 2. When recoupling, the plate 3 is rotated clockwise by the pin 6 and the lever 8 is disengaged from the element 15 by a camming recess 9 in the plate 3. The single locking plate 3 may be replaced by two or more such plates above and below the coupling plate 1. In another embodiment, Fig. 6 (not shown), the cam guide 11 is dispensed with, and the locking element is a link 27 pivotally connected to the lever 8 and acted upon by the spring 17. One side of the link 27 is bevelled at 29.

Abstract: 661,472. Preserving carbohydrate foods. ABBEY, A. (Dow Chemical Co.). Feb. 24, 1949, No. 5065/49. Class 49. [Also in Groups V and VIII] The resistance to micro-organisms of solid or unfermented liquid foods rich in carbohydrates is increased by bringing them into contact with dehydroacetic acid or an edible salt thereof such as sodium, potassium, ammonium or calcium dehydroacetate which may be incorporated in the food or applied to its surface as by a paper wrapper. Amounts of dehydroacetic acid between 0.01 and 0.5 per cent of the weight of the food may be mixed therein. Bread dough may contain amounts of dehydroacetic acid, e.g. up to 0.2 per cent by weight, which do not prevent rising. Citrus fruits may be given a resistant coating by dipping them into a latex containing 2 per cent of dehydroacetic acid based on the total dispersed solids. Wrappers may contain for example up to 5 per cent by weight of dehydroacetic acid or dehydroacetate.

Title: New methoxy methyl chlorobenzoic acid and derivatives thereof and process for preparing same
Inventor: RICHTER SIDNEY BERNARD
IPC: C07D307/12
Filed: 1964-02-07
Abstract: The invention comprises 2 - methoxy - 3 -methyl-6-chlorobenzoic acid, its anhydride, alkali metal salts, ammonium salts, morpholine salt, alkylamine salts in which the amine component is an unsubstituted alkyl amine of up to six carbon atoms, alkanol amine salts in which the amine component is an unsubstituted alkanol amine of up to six carbon atoms, esters in which the esterifying group is an unsubstituted alkyl group of from one to ten carbon atoms, butoxyethanol ester, tetrahydrofurfuryl alcohol ester, unsubstituted amide, alkyl amides in which the amine component is an unsubstituted alkyl amine of up to ten carbon atoms.  The free acid is prepared by methylating 3-methyl 6-chlorosalicylic acid, for example by first converting the 3-methyl-6-chlorosalicylic acid to its alkali metal salt with an alkali metal salt of a weak acid and reacting the alkali metal salt with an excess of a methylating agent, such as dimethyl sulphate.  The methylation reaction mixture is refluxed in an aqueous solution of an inorganic base, such as an alkali metal hydroxide, to hydrolyse the methyl ester and is then acidified with a mineral acid. The anhydride is made by reacting the free acid, the acid halide and an organic hydrogen halide acceptor, such as pyradine.  The acid halide is made by reaction of the free acid with a phosphorus trihalide, e.g. the trichloride.  The salts, esters and amides are made by conventional methods and suitable amines and alcohols are specified.  Detailed examples give the preparation of the acid, sodium, ammonium, dimethylamine, diethanolamine and morpholine salts, the ethyl, decyl, and n-butyl esters, the acid chloride, amide, N-n-decylamide and N,N-diethylamide.ALSO:Herbicidal compositions comprise 2-methoxy-3-methyl-6-chlorobenzoic acid, its anhydride, alkali metal salt, ammonium salt, morpholine salt, salts of an unsubstituted alkyl amine of up to six carbon atoms, salts of an unsubstituted alkanol amine of up to six carbon atoms, esters of an unsubstituted alkyl group of one to ten carbon atoms, butoxyethanol ester, tetrahydrofurfuryl ester, unsubstituted amide, amider of an unsubstituted alkyl amine of up to ten carbon atoms, in combination with an inert carrier.  Thus the compounds may be formulated as dusts, e.g. with talc or clays, the alkali metals being particularly suitable.  Preferably the compounds are applied as sprays using organic solvents such as xylene, kerosene or the methylated naphthalenes, the esters being particularly suitable.  The amine salts may be used in aqueous solution. Emulsifiers, wetting agents, other pesticides, stabilizers, activations, synergists, spreaders and adhesives can also be added.  Examples describe an emulsifiable concentrate of the free acid with methanol and a non-ionic detergent of the aromatic polyethylene glycol ether type; a concentrate of the n-butyl ester, xylene, kerosene and an alkyl aryl polyether alcohol emulsifier; a dust of the sodium salt and talc.
