Title: Fastening equipment
IPC: E04B1/41
Filed: 1976-09-13
Abstract: A method and arrangement for anchoring an object to a support structure having an anchoring hole includes inserting into the anchoring hole an anchoring member slightly smaller than the latter so that a clearance is formed in the anchoring hole about the exterior of the anchoring member, mounting a cap member in the anchoring hole and about an anchoring member so as to fix the latter in position in the anchoring hole, providing a flow-through passage which is in communication with the clearance on at least one of the cap and/or anchoring members, and injecting a hardenable substance through the flow-through passage and from there into the clearance so that the substance forms a plug about the anchoring member and fixes the same in the anchoring hole upon hardening.

Abstract: 1,048,374. Reciprocating pumps. STEWARTWARNER CORPORATION. Sept. 16, 1964 [Sept. 19, 1963], No. 37851/64. Heading F1A. In a reciprocating pump, the pump piston 78, operated on the delivery stroke by a tappet 58 and the eccentric end 26 of an input shaft 20 and on the suction stroke by a spring 80, is adapted to be periodically prevented from performing complete pumping strokes by means of a cam 42 with which a pin 66 on the tappet co-operates. The cam 42 is fixed to a gear 43 which forms part of a reduction gear driven from a pinion 40 on the input shaft 20. The cam contour, Fig. 5 (not shown), permits complete pumping strokes with pin 66 in part 105 and only partial strokes with the pin engaging contour 103. The transition region 108, Fig. 5, between the contours 103 and 105 may move the pin 66 against spring 60 to raise the tappet clear of the end 26 and prevent pumping strokes. By appropriate dimensioning of the cam 42 the piston 78 may be caused to reciprocate over a number of full stroke and/or partial stroke cycles per cam revolution.

Filed: 1957-12-10
Abstract: A gel is prepared by incorporating in water having a pH of from 3,0-7,0, 0,2%-1,0% by weight of a carboxymethyl ether of a readily water-soluble, high molecular weight dextran containing an average of between 0,8 and 1,5 carboxymethyl groups per anhydroglucose unit. The carboxy-methyl dextran is prepared by adding an aqueous solution of dextran, containing alkali metal hydroxide, to an aqueous solution of alkali metal chloracetate, maintaining the resulting solution at a temperature from 10 DEG -100 DEG C. for a time varying inversely with the temperature from 15 minutes to 2 hours, adjusting the pH of the resulting solution to from 2,0-3,0 and mixing it with a water-miscible alcohol or ketone to precipitate the carboxymethyl dextran and removing the aqueous phase.  The carboxymethyl dextran may be used as a thickening and stabilizing additive for polyvinyl acetate emulsions, natural and synthetic latex and water-based paints.  An example describes the incorporation of the carboxymethyl dextran into a styrene-butadiene latex-water-based paint having a pH of 6,5 and comprising lithopone, titanium dioxide, china clay, triethanolamine, sodium dioctyl sulphosuccinate, tributyl phosphate, dipentene, Pliolite latex emulsion and water.

Title: The manufacture of new indigoid dyestuffs
IPC: C09B7/10
Filed: 1929-12-23
Abstract: Thioindigo dyes are obtained by oxidation of hydroxypyrazolethionaphthenes, or by condensing the latter with isatins, thioisatins or the a -chlorides or arylides thereof.  The hydroxypyrazolethionaphthenes are produced from 6-aminoindazoles, in which at least one of the hydrogen atoms ortho to the amino group is unsubstituted and in which the benzene hydrogens and the hydrogen atom attached to the pyrazol nitrogen may be substituted by alkyl groups, by treating with a sulphocyanide and a halogen, splitting up the sulphocyanic group thus introduced, with formation of a mercapto group (cf. Specifications 257,619 and 306,607, [both in Class 2 (iii), Dyes &c.]), condensing with chloracetic acid and converting the resulting thioglycollic acid into the hydroxythionaphthene in known manner.  In examples (1) 6-aminoindazole is treated with ammonium sulphocyanide and bromine in the presence of methanol, and the resulting sulphocyano derivative is hydrolized with alcoholic caustic soda and zinc dust.  The product is condensed with chloracetic acid and 6-aminoindazole thioglycollic acid anhydride is precipitated by means of hydrochloric acid.  The anhydride is boiled with caustic soda, diazotized and treated with a sodium-copper cyanide.  By treating the 6-cyanoindazole-o-thioglycollic acid with sodium sulphide and heating the resulting aminopyrazole thionaphthene carboxylic acid with sulphuric acid, hydroxypyrazolethionaphthene is obtained.  The latter is oxidized with potassium ferricyanide to the dyestuff; it dyes cotton clear grey shades; (2) 6-amino-2-methylindazole is subjected to the same reactions, the resulting dyestuff dyeing cotton olive shades fast to boiling; (3) 5-methyl-6-aminoindazole (prepared by reducing 5-methyl-6-nitroindazole with iron and acetic acid) is similarly converted into the corresponding oxythionaphthene and then into the dyestuff by oxidation; (4) hydroxypyrazolethionaphthene is condensed with the following components: 3-hydroxy-5 : 6-benzothionaphthene-2-anil, 5-chlorisatin, 4 : 5-benzisatin-2-chloride and 6 : 7-benzo-3-hydroxythionaphthene.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the production of the 6-aminoindazole-o-thioglycollic acid from 6-aminoindazole, by baking the sulphate of the latter, converting the resulting o-sulphonic acid of 6-aminoindazole into the sulpho chloride, reducing, and transforming the mercaptan which is produced into the thioglycollic acid in known manner.  This subject-matter does not appear in the Specification as accepted.
