Title: Improvements in and relating to the moulding of synthetic resins
IPC: C08F2/02
Filed: 1951-11-15
Abstract: Synthetic polymerizable materials, such as methyl methacrylate and mixtures thereof with polymethyl methacrylate, are polymerized in contact with a surface with which the polymerized material should exactly conform by coating the surface with a polymerization catalyst, and then applying the polymerizable material to the catalyst layer whereby polymerization proceeds in a direction away from the surface to be reproduced.  Suitable surface catalysts are tertiary amines, such as dimethylaniline and sulphines, which may be applied in a varnish containing, e.g. nitrocellulose, mastic, or tricresyl phosphate dissolved in butyl alcohol, ethyl acetate, ethyl lactate, or ethyl ether.  The polymerizable material may also contain a catalyst such as benzoyl peroxide or a mixture thereof with dimethyl aniline.  The process may be employed in making dental and anatomical prostheses, artificial teeth, tooth fillings, and in moulding clasps and needles into polymerized material.

Title: Improvements in or relating to the electrolytic production of zinc from ores or the like
IPC: C22B19/02
Filed: 1924-12-29
Abstract: 249,764. Field, S., Petersson, E. F., Harris, W. E., and Metals Extraction Corporation, Ltd. Dec. 29, 1924. Roasting.- A zinc sulphide ore or product, containing iron and/or manganese, is roasted in air preferably at 650‹ C. until the sulphur content is so far reduced, for instance to about 9 per cent, that the admission of steam does not cause the production of sulphuretted hydrogen. Steam is then admitted for the remainder of the roasting, sulphur dioxide being liberated as before. This process prevents or minimizes the production of manganites and ferrites. A higher temperature may be used if desired. An example describes the treatment of Broken Hill ore. The roasted ore is treated with hot sulphuric acid, the zinc sulphate being purified and electrolyzed for example in the manner described in Specification 249,609, [Class 41, Electrolysis]. The Provisional Specification describes the roasting of the ore under such conditions that a minimum quantity of ferrites and manganites are formed, the proportion of sulphates formed being arranged to make up the losses of sulphuric acid in the extraction and electrolytic processes. Another method of roasting is also described in which the ore is heated in a muffle in steam so as to produce oxides and sulphates as before, but the sulphur is liberated as sulphuretted hydrogen. Specification 26350/12 also is referred to.

Title: Manufacture from acrylonitrile of copolymers capable of being dyed
IPC: C08F220/44
Filed: 1952-10-29
Abstract: Acrylonitrile is copolymerized with an acrylic or alpha-substituted acrylic acid amide containing tertiary amino nitrogen in the amide group, e.g. the dimethylaminomethyl, beta-dimethylaminoethyl, and beta-pyrollidinoethyl amides of acrylic acid, in the presence of another polymerizable vinyl compound, e.g. acrylamide, methyl and dimethyl acrylamides, methacrylic acid, vinyl formate, vinyl acetate and methyl vinyl sulphone.  Preferably the acrylonitrile is present in the mixture of monomers in preponderating amount.  Polymerization is preferably carried in an aqueous medium having an alkaline reaction, e.g. pH 7.2 to 7.8, with the aid of a water-soluble peroxy compound such as potassium or ammonium persulphate, which may be activated by the tertiary amino monomers or by reducing agents such as sodium sulphite, hyposulphite, pyrosulphite, or formaldehyde sulphoxylate.  The aqueous medium may contain a dispersing agent such as sodium cetyl sulphate.  The monomers and catalyst may be added gradually to the reaction mixture as polymerization proceeds.  The copolymers may be formed into films and fibres whose mechanical properties are improved by stretching and which are dyeable with acid, vat and acetate dyestuffs. Specification 728,605 is referred to.

Title: Improvements in automatic hydraulically-operated extraction presses
IPC: A23G1/08
Filed: 1926-11-01
Abstract: 262,072. Soc. Anon. des Ateliers Armand et DÚoune. Nov. 26, 1925, [Convention date]. Platen presses. - An automatic hydraulicallyoperated press with a movable pressure chamber, suitable for the extraction of oil from fruit and seeds, has filtering fabric arranged in front of a bed for the chamber and means for moving the fabric with the formed cake across and away from the bed. The wall of the press chamber is formed of two parts E, F, bolted together and movable on side bars D to and from the bed C which carries a perforated plate Q over which filter fabric is drawn by means of drums S, S<1>. The material under treatment is fed to the chamber through piping O, for example from a heater P, and, under pressure from the piston I, liquid is separated and passes through a perforated liner E<1> to a groove M in the part E and a nozzle N discharging into a trough A<1> and through the perforated plate Q to vertical channels R and a trough A<2>. On release of the pressure behind the piston I the piston is withdrawn by means of a constant pressure cylinder J connected to the piston by rods K. On release of pressure in pistons G, pistons H under constant pressure move the parts E, F away from the bed C. A stop J<1> carried by these parts releases by means of levers 1', H', a band brake operating on planet gear U, U<1> which serves both as a clutch and speed reducer in driving the drum S. The filter fabric is thus drawn over the plate Q and lifts the filter cake into a funnel D. A spring-controlled flap F<1>, which slopes laterally, closes after the passage of the cake,. and the cake then rolls to the side and from the apparatus. The filter cloth is drawn back to the operating position by a counterweight V, which rotates the drum S', the parts E, F are brought into engagement with the bed C by the pistons G, and the operative cycle can be repeated. A brush H<2> is provided for cleaning the filter cloth. The valves for controlling the hydraulic pressures are operated by a cam device Z. In the form of apparatus shown in Fig. 3 a perforated plate M' is fixed to the end of the piston I. A second filter cloth L<1> attached at one end to the top of this plate covers it during the pressure operation. The cloth rises with the cake but returns by its own weight when the cake is detached from it. The Specification as open to inspection under Sect. 91 (3) (a) describes also apparatus in which the press takes a double form, similar working parts being disposed at either end of a cylinder B in which two pistons I move in opposite directions. This subject-matter does not appear in the Specification as accepted.
