Title: Production of complex zinc compounds and their application
IPC: C01B25/45
Filed: 1946-08-19
Abstract: A viscous solution, which dries into water-insoluble, fire-resistant hard glossy films, is prepared by dissolving 25-125 parts tertiary zinc orthophosphate or ortho-arsenate, or a mixture thereof, in cold concentrated (35 per cent) aqueous ammonia, equivalent to 35 parts by weight of anhydrous ammonia.  A complex zinc phosphato- (or arsenato-) zinc ammine is produced. Up to 10 per cent of the dry weight of zinc, cupric, cadmium, nickelous, cobaltous or manganous hydroxide, or silver oxide, may be added to the solution.  The solutions are suitable for protecting say, timber against fire, weather and pests (fungus), and any tendency of the films formed to crack may be suppressed by adding pigments such as zinc or iron oxides, china clay, mica powder or carbon black.  Such solutions can be used as paints.

Title: Process for preparing resinous products and the resulting products
IPC: B03D1/06
Filed: 1952-10-01
Abstract: Amine salts of fatty acids are used as curing agents for glycidyl ethers of polyhydric alcohols or phenols containing at least one epoxy group per molecule.  Suitable amines are methylamine, dimethylamine, trimethylamine, ethylamine, diethylamine, triethylamine, ethanolamine, triethanolamine, 2-chlorethylamine, diisopropylamine, hexylamine, diethylenetriamine, 1,3-propanediamine, N, N-diethyl-1,3-propanediamine, cetyldimethylamine, nonylamine, hexamethylenediamine, morpholine, N-butyl morpholine, aniline, N, N-dimethylaniline, benzylamine, benzyldimethylaniline, dimethylaminomethylphenol, 2.4.6 tri (dimethylaminomethyl) phenol (see U.S.A. Specification 2,220,834), chloraniline, pyrrole, pyridine, piperidine, pyrimidine and piperazine.  The fatty acids may be saturated or unsaturated.  They preferably contain 2-12 carbon atoms per molecule.  The salts are preferably neutral i.e. contain no excess of either acid or amine.  The preferred glycidyl ethers are derived from bisphenol and epichlorhydrin.  Mixing of the salts with the ethers or solutions thereof may be helped by addition of a little water or by using amines with many carbon atoms/molecule.  Curing may be effected at relatively low temperatures e.g. 50 DEG -65 DEG C. The preferred temperature is between 80 DEG  and 200 DEG C.  The compositions to be cured may include solvents, fillers, dyes, pigments, plasticizers and other resins or resin-forming materials. In the examples glycidyl ethers from bisphenol and epichlorhydrin were cured with (1) and (2) the propionate, butyrate, isobutyrate, valerate, isovalerate and caproate of 2.4.6-tri (dimethylaminomethyl) phenol; (3) and (4) the 2-ethyl hexoate of 2.4.6-tri (dimethylaminomethyl) phenol; (5) trimethylamine isobutyrate; (6) dimethylamine acetate; (7) diethylenetriamine acetate; glass cloth plies were embedded in this composition and that of example (6) to form a laminate; (8) the formate, acetate, butyrate, caprylate, laurate and stearate of diethylenetriamine.  The composition also contains dibutyl phthalate; (9) diethylenetriamine acetate, the composition being used as an adhesive for aluminium; (10) diethylenetriamine acetate in a moulding powder containing also a -cellulose and calcium stearate; (11) diethylene triamine oleate and 2-ethyl hexoate, the resin being dissolved in a mixture of xylene and the methyl ether of ethylene glycol monoacetate.  The physical properties of compositions given to the examples are quoted often in comparative form.  Specifications 680,997 and 718,851 are referred to.

In an extrusion press having a billet piercing mandrel 5 which may be held stationary during extrusion or may move relatively to the extrusion ram 1, the mandrel is driven by a carriage 4 movable relatively to the ram frame 2 and the positions of the carriage before and after extrusion are determined by stops 38, 42 on a common adjustable member 31, which stops engage respectively with an abutment on the ram frame 2 and with a stationary abutment 25 which is movable from an operative to an inoperative position. The press ram is actuated by piston 27 in stationary cylinder 26. Piston 27 provides a cylinder 28 for piston 29 which actuates the carriage 4 for the mandrel 5. A pair of threaded spindles 31 in carriage 4 are adjusted simultaneously by gears 34 and each carry a stop 38 which engages the rear wall of the ram frame 2 for fixing the initial position of the mandrel. Stops 42 on the spindles engage fixed abutments 25 for determining the position of the mandrel after piercing the billet, which mandrel then co-operates with the die throat for forming a tube. If it is desired for the mandrel to move forwardly with the extruded tube, the abutments 25 are rotated through 90 degrees by handles 41 so that the stop 42 can pass through. In another embodiment, Figs. 8-12 (not shown), a single adjusting spindle is used. In a further embodiment, Fig. 15 (not shown), the mandrel operating cylinder is disposed behind the main ram cylinder.

Title: Improved devices for removing products from plastic-moulding or die-casting machines or other presses
IPC: B29C43/50
Filed: 1944-12-16
Abstract: 593,786. Removing moulded articles from presses. LUPTON, F. J., TURNER, G. M., FOX & OFFORD, Ltd., and V. & E. PLASTICS, Ltd. Dec. 16, 1944, No. 25278. [Class 87 (ii)] [Also in Group XXII] The invention is concerned with removing die-plates or moulds from a plastic-moulding or die-casting machine. The machine has two cradles or hinged carriers each of which is movable from a middle position, in which :it receives the die-plate or mould, to a side position where the cradle or die-plate can be tilted. The upper die-plate 12 is slidable horizontally in fixed guides 14, and the lower die-plate (not shown )is vertically reciprocable by a hydraulic press. After a moulding operation, the lower dieplate is lowered and the operator grasps a handle 17 on the upper die-plate and pulls the latter out on to a cradle 19 which is slidably hinged on rod 21. He then slides the cradle along to one end of the rod, and tilts it up vertically so that the underface of the upper dieplate carrying the moulded articles (screw threaded parts), is accessible and the articles may be detached. A second cradle, holding a second empty die-plate, is then slid from the other end of the rod into a central position, and the second die-plate is pushed from its cradle into the guides 14. Means are provided for ensuring that a cradle cannot move sideways nor rotate on the rod 21 between the initiation and completion of the outward sliding movement of a die-plate. Catches 29 hold the cradles in a vertical position. The cradles may be power-operated. In the application of the invention to die-casting machines the lower die-plate is used but the place of the upper die-plate 12 is taken by a mould arranged to slide in and out of the machine. In modifications (1) (Fig. 7), the die-plates 12 are received on members 30 pivoted on vertical shafts 31, (2) the lower die-plate is fixed, (3) the moulding pressure is applied horizontally.
