Abstract: 992,248. Copying lathes. VERWALTUNGSGESELLSCHAFT DER WERKZEUGMASCHINENFABRIK OERLIKON. Aug. 18, 1961 [Sept. 9, 1960], No. 29856/61. Heading B3T. A copying device for lathes and like machine tools has a feeler with a number of stepwise feeler tips co-operating with a templet mounted on a vertically indexible carrier so that the templet can be brought into register with each of the different feeler tips. The sliding member 9, Fig. 1, of the control valve for the copying cylinder 4 carries a depending plate on which the feeler 10 is mounted. The feeler has two operative stepped edges and can be bolted in a second position at 180 degrees to the first when a new set of steps are required. The securing bolt 5, 8, Fig. 2, for the feeler is " necked " so that it can shear to avoid damage to other parts. The stepped edges of the feeler are brought selectively into operative engagement with a templet 17 secured to an adjustable slide 21 mounted for indexible vertical movement on a support 26 which is bolted to a member slidable longitudinally on guides 12, Fig. 1, of the lathe bed. The vertical movement of the templet carrier to bring the templet into line with the selected feeler step is effected electrically by moving a selector switch 43, Fig. 2. This may be effected automatically. The lowermost step of the feeler has a pointed edge to follow sharp recesses and the final step on the feeler is small so that the last edge effects a finishing operation. More than one templet may be used, a second one 22 being shown clamped below the main templet 17.

Title: Improvements in or relating to polyurethane resins
Inventor: PHILLIPS LESLIE NATHAN
IPC: C08G18/10
Filed: 1957-09-27
Abstract: Films and coatings on glass or glass fibre/polyester resin laminates are formed from a polyurethane product obtained by reacting (a) a polyurethane adduct derived from the reaction of (1) a water-free hydroxyl-terminated linear-polyester having an acid number of no greater than 5 with (2) an excess of a water-free organic diisocyanate having two reactive NCO groups, with (b) a cross-linking agent consisting of a tetrahydroxy polyol containing a tertiary nitrogen atom, said adduct and said cross-linking agent being combined in such stoichiometric proportions as to produce an approximate 1:1 ratio of hydroxy groups to NCO groups.  After adding the cross-linking agent the mixture may be applied to the surface where drying and curing take place.  As a primer there may first be applied to the surface a coating of a solution of an amine-hardenable epoxy resin.  In examples the polyurethane compositions are prepared in toluene from glycol/adipic acid or glycol/sebacic acid polyesters; diisocyanato-diphenylmethane or tolylene or naphthalene diisocyanates; and N, N, N1, N1-tetrakis (2-hydroxypropylene)-ethylene diamine.ALSO:A process of forming a substantially bubble-free polyurethane product comprises reacting (a) a polyurethane adduct derived from the reaction of (1) a water-free hydroxyl-terminated linear polyester having an acid number of no greater than 5 with (2) an excess of a water-free organic diisocyanate having two reactive NCO groups, with (b) a cross-linking agent consisting of a tertrahydroxy polyol containing a tertiary nitrogen atom, said adduct and said cross-linking agent being combined in such stoichiometric proportions as to produce an approximate 1:1 ratio of hydroxy groups to NCO groups.  After adding the cross-linking agent the mixture may be applied to form a film on a mould surface, where it cures rapidly.  The amount of NCO groups in the product from reaction (1) is determined by refluxing with excess dibutylamine and back-titrating with hydrochloric acid.  In Examples (1) an alkyd of acid no. 4.0 from the reaction of glycol and adipic acid in the presence of aluminium is reacted in toluene with excess tolylene diisocyanate and to the resulting mixture is added N, N, N1, N1-tetrakis (2-hydroxypropyl) ethylene diamine in ethyl acetate. Films of the mixture were dried at room temperature or at 100 DEG C. until cured; (2) a polyester from glycol and sebacic acid is reacted similarly; (3) a product from an adipic acid/glycol polyester, naphthalene diisocyanate and N, N, N1, N1-tetrakis (2-hydroxy-propylene) ethylene diamine, with acetyl chloride as inhibitor, is used to coat a glass fibre/polyester laminate; (4) in a process similar to (3) the adduct is prepared from polyethylene sebacate, p, p1 - diisocyanato - diphenylmethan and toluylene diisocyanate.
