Title: Improvements in and relating to tools for truing valves and valve seats
IPC: B24B15/00
Filed: 1930-08-12
Abstract: 361,345. Refacing valves and valve seatings. CHRISTIE, W. S., 14, Bray Street, Bendigo, Victoria, Australia. Aug. 12, 1930, No. 24108. Convention date, Aug. 19, 1929. [Class 83 (iii).] Portable turning-apparatus ; cutters.-Apparatus for resurfacing valves or valve seatings such as those of internal-combustion engines comprises cutting or surfacing elements which are arranged in. dovetail slots in a conical body member. For refacing valves, the tool consists of a body 7 having a conical recess which accommodates in tapered dovetail grooves 18 a number of correspondingly-tapered cutting elements 15. These elements may have serrated concave cutting-faces, Fig. 9, or may have cutting edges similar to those of scrapers. A central bore in the body 7 is fitted with a pair of coaxial guide members 9, 10, which screw into the body and receive the stem 19 of the valve to be refaced. In operation the body is gripped in a vice by the boss 8 and the valve is rotated by means of a driver engaging the slot 22. For finishing the valve, the cutting-elements may be removed and replaced by a ring 23 of emerycloth. The tool for refacing the seating comprises a conical body 24 having tapered dovetail recesses to receive tapered convex cutting-elements 26 which may be shaped as shown in Fig. 10. A guide member 34 bored to fit the valve stem is screwed into the body, a flange 35 on the guide engaging the tapered cutters to force them along their slots. The valve stem is gripped by a screw 32 and the seating is refaced by rotating the valve head, Fig. 5, by means of a suitable driver. For finishing the seating a ring of emery cloth may be applied to the body 24 and the tool operated as before. The guides 10, 34 may be interchangeable and a series of such guides may be provided to accommodate valve stems of different sizes.

Title: Improvements in the manufacture and production of intaglio printing inks
IPC: C09D11/02
Filed: 1934-08-22
Abstract: Intaglio printing-inks are prepared by emulsifying solutions of resins in benzine hydrocarbons of high boiling point (130--180 DEG C.) and high flash point (above 30 DEG  C.) with dyestuffs and water or aqueous dyestuff pastes, using as emulsifying-agents reaction products of high-molecular aliphatic or cycloaliphatic carboxylic acids or alcohols with alkylene oxides, polyglycols, or aminoalkyl or hydroxyalkyl sulphonic acids.  The resin may be obtained from polybasic acids and polyhydric alcohols, colophony, or cyclohexanone, and the resin solution is added to the dyestuff paste triturated with the solution of the emulsifying-agent. According to examples: (a) a glycerine-phthalic anhydride-linseed oil resin dissolved in hydrocarbon is emulsified with Hansa Yellow GT paste, using as emulsifier a condensation product from oleic acid and ethylene oxide; (b) hardened colophony dissolved in ethylene glycol monoethyl ether and hydrocarbon is emulsified with Permanent Red 4R paste and the emulsifier used in example (a); (c) a resin obtained from a mixture of cyclohexanone and methyl cyclohexanone dissolved in hydrocarbon is emulsified with Milori Blue paste using as emulsifier the reaction product of ethylene oxide and stearic acid.  Specification 414,801 is referred to.

Abstract: 790,870. Electrodeposition of refractory metals. HORIZONS TITANIUM CORPORATION. Aug. 26, 1955 [Sept. 10, 1954], No. 24542/55. Class 41. In the electrodeposition of the refractory metals of Groups IVa and Va, water and contaminant elements, e.g. iron, chromium and aluminium, whose salts and oxides are more electropositive than those of the said refractory metals, are removed from the fused salt electrolyte by a preliminary electrolysis in an inert atmosphere at a cell voltage above that required to decompose said water and contaminant salts and oxides for a time sufficient to effect removal of the contaminants, and, after changing the cathode, electrolysing the purified bath to deposit the refractory metal cathodically. Typically the preliminary electrolysis is carried out at the same voltage as for the subsequent refractory metal deposition but with only half the current density. In examples, the bath purified consists of potassium fluotitanate or fluozirconate with sodium chloride, the graphite crucible being the anode and the cathode being graphite during the preliminary electrolysis and steel during the refractory metal deposition.
