Title: Emitter for irrigation systems
IPC: B05B15/02
Filed: 1975-03-21
Abstract: 1479409 Nozzles HARMONY EMITTER CO Inc 21 March 1975 [1 April 1974] 11883/75 Heading B2F [Also in Divisions Al and F2] A water emitter, providing a constant rate of flow, for an irrigation system, comprises a cylindrical envelope 36 and a pair of D-shaped sections 20, 21 closed at one end which each have a semi-cylindrical section 26, 27 and a respective resilient sheet 22, 23 provided on their respective adjacent surfaces with respective ribs 40, 41 running at an angle of 45 to the length direction of the sheets. The ribs in the respective surfaces are orthogonal to each other and form interstices and define a passage 42 for water flow which passage may expand if the rate of flow of water increases. Water also enters the interior chambers 34, 35 of the sections and biases the sheets together proportionally to the water pressure. Thus if the water pressure increases it tends to increase the rate of flow through the passageway, forcing the sheets further apart, but it also tends through the increased pressure in chambers 34, 35 to increase the bias urging the sheets together, and thus the balance of forces on the sheets is maintained, providing a constant rate of flow through the passage 42. Ridges 24, 25 are included to increase the longitudinal rigidity of the sheets.

Abstract: 166,998. Marks, E. C. R., (Nordiska Kullagers F÷rsõljnings Aktiebolag). April 29, 1920. Roller bearings.-The rollers 3 are so proportioned that the moment of inertia of each roller about its normal axis of rotation exceeds that about any other axis passing through its centre of gravity. One or both of the races have the shape of spherical surfaces or of surfaces having longer radii of curvature than those of the spherical surfaces up to the limit of cylindrical surfaces. The rollers are transversely convex, the radius of curvature being greater than the radius of the axial figure of projection of the roller, but equal to the radius of transverse curvature of one race, and less than the radius of transverse curvature of the other race, if this be concave or cylindrical. Several forms are shown, Fig. 1 showing a spherical outer race 5 and a cylindrical inner race 4. In each case, the rollers may be readily inserted by tilting one of the race rings. Specification 117,341 is referred to.

Abstract: 1,207,674. Bottle corks. GRANTS OF ST. JAMES'S Ltd. 23 Feb., 1968 [14 March, 1967], No. 11999/67. Heading B8T. Bottle corks are sealed by treating them with an organosilicon compound, for example a silicone oil such as a methyl or methyl phenyl polysiloxane or a linear dimethyl polysiloxane. The corks may be soaked in an emulsion of the organosilicon compound in an aqueous medium and then dried, or alternatively dipped in a solution of the organosilicon compound in a volatile organic solvent, e.g. a hydrocarbon or halogenated hydrocarbon such as light petroleum or trichloroethylene, drained, and dried. It is also possible to spray the corks with the emulsion. A preservative such as sodium metabisulphite or sulphur dioxide may be added to the emulsion or solution to sterilize the corks which may then be packed in hermeticallysealed sterile containers, e.g. polythene bags. The corks may be soaked in the emulsion in a sealed container and a vacuum applied, and it is also possible to apply a vacuum to the corks in the container in the dry state to remove air from the pores and then add the emulsion under vacuum.

Patent GB-577992-A (GB)
Title: Production of allyl alcohol and esters thereof
IPC: C07C33/03
Filed: 1943-08-04
Abstract: Allyl alcohol or esters thereof are prepared by reacting propylene at a temperature of between 50 DEG  and 350 DEG  C. with a liquid solution or suspension of selenium dioxide or trioxide or tellurium dioxide or trioxide.  Preferably, the selenium or tellurium oxides are dissolved in a suitable solvent and the gaseous propylene dissolved or passed into the solution.  The solvent may be an inert liquid or liquids such as water dioxane, benzene, a saturated nitrile or a saturated hydrocarbon, in which case allyl alcohol is obtained or may be a liquid carboxylic acid which reacts with the allyl alcohol formed to produce the corresponding allyl alcohol ester which, if desired, may be subsequently hydrolysed to allyl alcohol. The acid may be present in anhydrous or substantially anhydrous form, such as glacial acetic acid, or acetic acid with acetic anhydride (or a similar mixture of their homologues), or enough water to hydrolyse the ester may be present or formed in the solution or be added as the ester is formed or subsequent to its formation.  The gaseous propylene may have other gaseous inert or oxidising materials admixed with it such as air, nitrogen, steam, oxides or peroxides or mixtures thereof.  An advantageous reaction temperature is that at which the liquid mixture may be refluxed.  If sufficient water be present, the allyl alcohol may be distilled off continuously as its azeotropic mixture, or if the reaction is carried out under anhydrous acid conditions the ester may be distilled off continuously.  The solution may be refluxed at atmospheric, reduced or increased pressure.  In examples (1) and (2), selenium dioxide was dissolved in a mixture of glacial acetic acid and acetic anhydride, the solution maintained at 100 DEG  C. and propylene passed in; after neutralization with aqueous caustic soda, an allyl alcohol water azeotrope was distilled off; (3) selenium dioxide in a solution of glacial acetic acid and acetic anhydride was maintained at 120-130 DEG  C. and propylene passed in; allyl acetate was distilled off continuously as soon as formed. Reference is made to the use of propionic acid and its anhydride and their homologues in place of acetic acid and acetic anhydride. Specification 376,306 is referred to.  The Specification as open to inspection under Sect 91 relates to the oxidation of propylene and the normal butylenes to the corresponding allyl-type unsaturated alcohols (or esters when an organic acid is present) by reaction with a sulphur oxide, specifically sulphur trioxide, in addition to those mentioned above.  It is stated that when sulphur trioxide is used, the oxidation is preferably executed in the absence of a solvent for sulphur trioxide.  This subject-matter does not appear in the Specification as accepted.
