Title: Method and apparatus for surface cleaning using ultrasonic energy
IPC: B08B3/12
Filed: 1960-05-12
Abstract: A combined chemical and ultrasonic cleaning method for cleaning the surfaces of metal, plastic or ceramic objects, using separate tanks, comprises immersing the object in a first bath having a pH value differing from 7, removing the object and conveying it to a second neutralizing bath, having a pH value differing from 7 and which may or may not include detergent, and then ultrasonically cavitating this second bath, e.g. at frequencies up to 400 kc./s. preferably 40 kc./s., while the object is immersed therein, preferably rotating, so removing contaminants (including air) from its surface.  The means for producing ultrasonic cavitation is by transducers, e.g. of quartz but preferably a piezoelectric ceramic crystal such as BaTiO3, which may be so located to provide a zone of high intensity ultrasonic energy which impinges on the zone from a plurality of directions. For example, for removing rust or scale from metal objects, the first bath may contain a solution of hydrofluoric, hydrochloric, nitric, chromic, sulphuric, or phosphoric acid, or mixtures thereof, e.g. 25% HNO3 and 3% HCl or HF by volume, preferably at 160-200  DEG F., the objects being immersed for up to 10 minutes; then the objects may be immersed in a second bath, e.g. 10% NaOH by volume, while being ultrasonically cavitated for only a few seconds.  For removing smog from ceramic objects, the first bath may contain caustic soda or tri-sodium phosphate solution, and the second bath, an ultrasonically cavitated solution of sulphuric acid.

Title: An improved method of oxidizing aluminum alkyls
Filed: 1957-05-28
Abstract: Aluminium alcoholates containing 2-20 carbon atoms in the alcoholic groups are preparing by oxidizing with an oxygen-containing gas, e.g. air, an aluminium trialkyl in solution in a mixture comprising 60-90 per cent by weight of an inert halogenated hydrocarbon solvent, or at least 80 per cent by weight of an inert hydrocarbon solvent, for a time sufficient to substantially completely oxidize the aluminium alkyl to the corresponding alcoholate.  Preferred conditions are a temperature of 0-100 DEG  C. and atmospheric pressure.  Preferably the alkyl groups average 8-12 carbon atoms each conclusive.  Suitable halogenated solvents include aromatic compounds such as chlorobenzene, o- and p-chlorotoluene, o- and p-dichlorobenzene, benzotrichloride, 2,4-dichlorotoluene and o-xylyl chloride; halogenated acyclic compounds such as CCl4 and the "Freons" (Registered Trade Mark) and cycloaliphatic compounds such as perfluorodimethylcyclohexane and perfluorotetradecahydrophenanthrene. Brominated compounds may also be used.  Suitable hydrocarbon solvents include aromatic compounds such as benzene and toluene, and C5-8 paraffins. The product aluminium alcoholates may be hydrolysed to the free alcohol, preferably after removal of solvent.  Preferably the hydrolysis, which may be effected by conventional means, is carried out in the presence of a hydrocarbon diluent such as pentane or hexane, e.g. 0.5-2 volumes of diluent being used.  In examples: (1), (2), (4), (5) aluminium trioctyl; (3), (6), (7) aluminium trihexyl; and (8) aluminium tridodecyl are oxidized with air.

Abstract: 1,261,349. Embossed cellular coating. DUNLOP SEMTEX Ltd. 8 April, 1969 [9 April, 1968], No. 16903/68. Heading B2E. [Also in Divisions B6 and C3] Embossed cellular sheet material is produced by treating portions of the surface of a sheet or coating of thermoplastic polymer containing an ester or metal salt of azodiformic acid as blowing agent with a liquid containing a compound which will react with the blowing agent so that it can no longer function as a blowing agent, and heating to decompose the blowing agent. The thermoplastic polymer may be polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, and may be adhered to a backing sheet e.g. a latex-bonded asbestos felt (Example 1), a calendered vinyl resin sheet (Example 2), a resin-bonded cellulose felt (Example 3), or a woven fabric. The liquid containing the reactant for the blowing agent may be a printing ink containing resin e.g. vinyl chloride-vinyl acetate copolymer, plasticiser, stabilisers, pigment and solvent. The reactant may form an adduct with the blowing agents. Examples of reactants are aromatic amines, alkyl phosphites, aliphatic amines, reducing compounds e.g. hydroquinone, and trimellitic anhydride. The amount of penetration of the reactant composition through the expandable sheet or coating may be controlled. The embossed surface may be covered with a transparent wear layer e.g. a polyvinyl chloride composition.

Title: Improvements in and relating to epoxide compositions
IPC: C08G59/68
Filed: 1961-05-10
Abstract: Polyepoxides containing at least one cyclohexene oxide or cyclopentene oxide residue are polymerized or cured with the aid of an active organic hardener and a tetravalent tin salt of an aliphatic monocarboxylic or dicarboxylic acid having 1-18 carbon atoms, or a stannic alkoxide, Sn(OR)4, where R is an aliphatic hydrocarbon radical containing 1-18 carbon atoms. The term active organic hardener is defined as a compound containing two or more groups which are reactive with epoxy groups.  Long list of suitable compounds are given.  Many suitable polyepoxides and suitable tin compounds are also listed.  In examples 1 to 15 and 19 to 21 the polyepoxide was 3,4-epoxy-6-methylcyclohexylmethyl - 3,4 - epoxy - 6 - methylcyclohexane carboxylate, the tin catalyst was stannic n-amyloxide or stannic-t.-amyloxide, and the hardener was 1,2,6-hexanetriol, bisphenol A, methyl Nadic anhydride, tolylene diisocyanate, sebacic acid, or Dimer acid.  In Examples 22, 24, 26, 28 and 30, stannic-t.-amyloxide and methylbicyclo[2,2,1]heptene-2,3 dicarboxylic anhydride were used to cure bis(2,3-epoxycyclopentyl)ether, vinylcyclohexenedioxide, dicyclopentadiene dioxide, bis(3,4epoxy - 6 - methylcyclohexylmethyl)adipate, and 1,1,1 - trimethylolpropane - tris - (3,4 - epoxycyclohexanecarboxylate). The corresponding odd-numbered examples have no hardener and are for comparison.  In Example 32 a foam was prepared using stannic-t.-amyloxide dissolved in trichlorofluoromethane, 3,4-epoxy -6-methylcyclohexylmethyl-3,4-epoxy-6-methylcyclohexane carboxylate, tolylenediisocyanate, a surfactant of formula OBu]3' <FORM:0991910/C3/1> and a half-acid ester prepared by reacting the propylene oxide adduct of pentaerythritol with excess maleic anhydride.  Example 62 is similar, but uses stannic octoate as the catalyst. Other examples illustrate the use of stannic acetate or stannic octoate with 3,4-epoxy-6-methylcyclohexylmethyl - 3,4 - epoxy - 6 - methylcyclohexanecarboxylate and various hardeners.  Mixtures of this same epoxide with stannic octoate, polyol, e.g. hexanetriol and anhydride, e.g. maleic anhydride cured isothermonically. In Examples 52-61, the effectiveness of stannic octoate was demonstrated with a variety of polyepoxides and with methylbicyclo-[2,2,1]-heptene -2,3-dicarboxylic anhydride as hardener.

Abstract: 113,107. Mackey, A. Dec. 1, 1916. Dovetailing.-In a machine for dovetailing the ends of boards for forming boxes &c., a. bundle of boards is formed on a table A with the assistance of an angularly adjustable fence and is trimmed and sawn to length by a reciprocating circular saw a, a conveyer B then feeds the bundle on to a carriage I adapted to be moved along rails G, H so that the bundle is operated upon by successive sets of saws N, 0 which are arranged in pairs to dovetail both ends of the bundle simultaneously. Each tenon or recess is formed in two successive operations by presenting the boards at different angles to the cutters; between the two operations, the carriage I is automatically tilted, as indicated diagrammatically in Fig. 3, so that the tenons or recesses are completed in one travel of the carriage I. The tenons are formed by sets of saws O of equal diameters, and the recesses by sets N of regularly varying diameters mounted on inclined shafts. To enable the saws N to be thrown out of action while the saws O are in operative position, and vice versa, their shafts are carried in brackets R adjustable along guide-bars J by screws S. Vertical adjustment of the saws is effected by screws w. The carriage I comprises upper bars 30 slidably supported by the guideways H, lower bars 33 slidable in the guideways G, and end bars 32 pivoted at 25 to the upper bars 30; the lower ends of the bars 32 at one end of the carriage are pivoted at 25<a> to the bars 33, and at the other end of the carriage to pawls 29<a> engaging racks on the bars 33. These pawls are connected by links 28 to pawls 29 pivoted at 22 to one set of bars 30 and adapted to engage racks formed on bars 27 which connect the bars 30 together; the pawls and racks enable the bars 32 to be adjusted to bundles of different sizes. A weighted bar 2 clamps the bundles down. The carriage is drawn by a cable 31, and when its base meets a stop Q, the looseness of the joints or the flexibility of the ways G, H allows the pull of the cable to tilt the carriage and the bundle in the opposite direction; a finger Q<1> depresses the stop Q to allow the carriage to proceed. The carriage runs off the rails G at the end of the travel to allow the bottom 33 to fall down to discharge the bundle as indicated in Fig. 3, and the falling bundle may operate a reversing- mechanism to return the carriage.
