Title: Improvements in and relating to resinous reaction products of aldehydes and triazinederivatives
IPC: C08G12/34
Filed: 1943-07-27
Abstract: A synthetic resin is produced by heating under alkaline conditions an aldehyde or compound engendering formaldehyde under the conditions of the reaction with (benzene sulphonyl hydrazino)-diamino- or dimethylamino-s-triazine.  Reaction may be carried out at atmospheric, sub- or super-atmospheric pressure. Alkaline conditions may be produced by any common alkali or an amine.  If desired, a mixture of a nitrogen-containing base and a fixed alkali may be used. Solvents, diluents, other natural or synthetic modifying agents or conventional modifying agents may be included in the reaction mixture, the reagents being mixed in any desired order, e.g. as described in Specification 542,932. Products may be thermosetting or thermoplastic and may be mixed with fillers, e.g. wood flour, glass fibres, asbestos, mineral wool, mica or cloth cuttings, dyes, pigments, lubricants, plasticisers and curing agents.  Liquid intermediate condensation products may be concentrated or diluted with solvents to form coating, laminating or impregnating compositions or may be used as casting resins.  Examples describe the preparation of the resinous condensation product from formaldehyde and the triazine derivative or a mixture thereof with urea, or p-ureido benzene sulphonamide, and the preparation of moulding powders by addition to the condensation product of a -cellulose, zinc stearate and chloracetamide, and drying and grinding.  Other examples describe the use of acrolein in place of formaldehyde in the preparation of a thermosetting condensation product and the use as modifying agents of butyl alcohol to produce a product suitable as a baking varnish, or as a modifier of varnishes from aminoplastic or alkyd resins, of acetamide glycerine, diethyl malonate or polyvinyl alcohol to produce a thermoplastic product which could be cured by addition of curing agents.  Lists of suitable curing agents and of aldehydes are given in the Specification.  Specification 542,934 also is referred to.  The Specification as open to inspection under Sect. 91 includes the use of triazine derivatives corresponding to the general formula <FORM:0595550/IV/1> where n is 1, 2 or 3, R is H, a hydrocarbon or a substituted hydrocarbon radical, and R1 is an aryl or substituted aryl radical.  Lists are given of possibilities for R, R1 and the triazine derivatives.  The lists of modifying agents, aldehydes and curing agents are also longer than in the accepted Specification.  The reaction medium may be acid, alkaline or neutral and may not be heated.  An example is given employing dimethylol urea as the aldehydic component of the reaction mixture.  This subject-matter does not appear in the Specification as accepted.

Abstract: 377,316. Coin-actuated game apparatus. BRADLEY, L. C., 51, Havelock Road, Handsworth, and PERRY BARR METAL CO., Ltd., Wellhead Lane, Perry Barr, both in Birmingham. April 29, 1931, No. 12590. [Class 27.] Tivoli billiards and the like.-In game apparatus of the kind in which a coin or token is projected or allowed to fall past a number of deflecting pins towards a number of receptacles, a coin or token is inserted in a slot 13, Fig. 1, and delivered, by rocking a handle 16, to a testing mechanism of usual construction from which it falls to a rotary member 29 driven by a belt from a rotatable knob 32. The member 29 has a projection 30 with curved facets 31 which flick the coin past deflecting pins 33, the coin falling through tapering passages 35, Fig. 3, in a bar 34 to channel-sectioned guides or receptacles 36. The guides 36 are arranged at an angle to the front of the apparatus and overlap as shown in Fig. 4, so that a large number can be provided. The coins are retained in the guides by pins 40 on vertical rotatable rods 42 held in retaining position by torsion springs 43. At the top of each guide are slots 46, 48, Fig. 6, formed in opposite edges, and a deflecting pin 47 arranged beneath the slot 48. The slot 46 allows the coins to pass the pin 47 until the guide is full, when the next coin entering is deflected through the opening 48 and acts as a coupler in release mechanism which permits the delivery of the coins in that guide as a prize. These coins drop to a shoot 38 leading to a delivering scoop 8 in the front of the apparatus. The fronts of the guides 36 are open so that their contents can be viewed through a glass panel 61. An indicator plate 64 shows the number of discs or coins in the various guides, so that the player can choose which guide he will endeavour to direct the coin he has inserted. The handle 16 operates a quadrant 15, Fig. 5, which transfers the inserted coin or disc to a slot 18 leading to a coin-tester 25. The quadrant through a connecting-rod 23 and bell-crank lever 20 actuates a vertical rod 21 to operate the prize-delivery mechanism. Prize-delivering mechanism; coin action, mechanical-connection.-The coin deflected through the opening 48 in a full guide or receptacle 36 passes to a compartment at the back of the guide having slots at the back and one side. The side slot is normally blocked by one cam 54 of a bell-crank lever on the rod 42 of that guide to retain the coin in the compartment. By actuating the handle 16, the rod 21 through links 59, 58, Fig. 3, rocks a shaft 55 so that an arm 57 on the shafts sweeps through the back slot of the compartment and presses the coin down against the side of the arm 54 to rotate the rod 42, a horn 60 on the arm 57 then engaging the other arm of the bellcrank lever 54 to continue the rotation of the rod 42 thereby withdrawing the pin 40 and allowing the coins in the guide to slide out. The releasing coin drops to a money-drawer 7 through the front of which the delivery scoop 8 passes.

Title: Introducing gas into liquid
IPC: C02F3/12
Filed: 1975-06-23
Abstract: 1518261 Dispersing gases in liquids BREWING PATENTS Ltd 23 June 1975 [22 March 1974] 12923/74 Heading B1C A method of introducing a relatively insoluble gas into a liquid (e.g. a fermentated liquid) comprises dissolving the gas under superatmospheric pressure, in a carrier liquid mixable with the said liquid, and introducing- the solution into the said liquid in such a way that the formation of gas bubbles is restricted or avoided. A relatively insoluble gas is defined in such a way as to include oxygen and nitrogen but. exclude carbon dioxide. The formation of bubbles may be avoided by injecting the gas/liquid solution vigorously through a short tubular nozzle, it being stated that the fall in pressure is thus so rapid that bubbles have no time to form; injecting it at low velocity through a nozzle such as one in which the pressure drops gradually in the length of the nozzle, such as a coil of stainless steel tube which may be rolled : to the section shown in Fig. 1; or a nozzle as shown in Fig. 2 which ejects the liquid as a sheet. Examples relate- -to the introduction of oxygen into brewing wort of high specific gravity with avoidance of foam production and of release of dissolved carbon dioxide. The carrier liquid may be water or brewing liquor and may be mixed with part of the brewing wort at high pressure and the pressure than reduced; it may be cooled to 2‹C to enable the gas content to be increased repeated slow injections of carrier liquid may be made at intervals into the brewing liquor to reduce the ester level. Water saturated with oxygen at a partial pressure of 5 atmospheres absolute can be introduced into fermentation liquid at atmospheric pressure at a dilution rate of 2% giving an oxygen content of 6p.p.m., or at 10 atmospheres at a dilution rate of 1:9 into a circulation line of brewing liquor, or into an oxygen-free wort on its way to the fermentation vessel.
