Title: Improvements in the manufacture of rubber and similar vegetable resins
IPC: C08J3/21
Filed: 1926-11-13
Abstract: 290,313. Dunlop Rubber Co., Ltd., Twiss, D. F., and Murphy, E. A. Nov. 13, 1926. Latex, treating.-During the concentration by evaporation of latex to which compounding ingredients and stabilizing agents have previously been added, a gentle continuous mixing action is maintained. The stabilizing agents may include colloids such as glue, gelatine, casein, vegetable gums, dextrin or soap, an alkali capable of acting with the natural acids of the, latex, or saline substances such as sodium silicate or viscose which impart an alkaline reaction. Preferably there is employed a non-volatile alkali or an alkalimetal derivative of a colloid in proportion just sufficient to facilitate concentration without immediate coagulation. When an alkali-colloid is employed it may be prepared from an acid of high molecular weight or from a protein substance and may be added to the latex as such or substances may be added to the latex so that the alkali-colloid is formed by chemical action therein. In an example, 8 parts zinc oxide, 2.5 sulphur, 1 lamp black, 20 talc, 15 whiting, 2 emulsified paraffin wax, 1 finely-ground mineral rubber, are mixed with 100 parts of water containing 0.1 part caustic potash, 0.3 oleac acid and 0.3 casein. Ammomia-preserved latex is then added in the proportion of 60 parts rubber and the whole mixed and concentrated at 70‹ C. After concentration, ammonia and an accelerator such as 0.3 part diethylammonium diethyldithiocarbonate are added during cooling, the mixing action being continued until both are uniformly distributed. Other examples are given in one of which sulphur and piperidine piperidine-carbo. thianolate are added during the latter part of the concentration. The addition of aqueous ammonia to the cencentrates prevents thickening to a stiff paste. Mixtures of two or more aqueous dispersions of rubber, gutta-percha, balata and similar resins may be concentrated according to the invention.

Patent GB-340938-A (GB)
IPC: G04B21/08
Filed: 1929-09-30
Abstract: 340,938. Clocks combined with gramophones. METTLER, L. FAVRE-, 72, Route de Florissant, Geneva, Switzerland. Sept. 30, 1929, No. 29610. Convention date, Oct. 5, 1928. [Class 139.] A self-contained independent device for positively starting the turntable of a gramophone is under the control of an adjustable timepiece which is mounted on the arm A of a fork-shaped baseplate A,A<1>. Under the action of the clockwork-driven mechanism16, the end 21 of a lever 2, pivoted at 22, is capable of taking up its position at two different heights. The outer end of an arm 3 which is rotatable about a screw 4 carries a stop pin 5. A spiral spring 6 ensures that the end 10 of the arm 3 always lies behind the vertical member 9<1> of an arm 9 rotatable around a vertical post 7. Mounted on the post 7 is a spiral spring 7<11> which can be tensioned by rotating a knurled disc 12 on a screw thread at the upper end of the post 7, the disc being secured by a locking screw 11. The lower end of the spring 7<11> is connected by a screw 15 to a rotatable member 8. The arm 8<1> of the member 8 is provided with a rubber pin 8<11> which acts as a brake and starting device for the turntable 24. In operation, the pointer 17 of the clockwork mechanism is set; the spring 7<11> is further torsioned by turning the arm 9 to bring the member 9<1> into engagement with the stop 10 ; and the arm 8<1> with the pin 8<11> is pushed under the turntable 24. The spring 7<11> thus acts by tensional as well as torsional action, and holds the device upon the gramophone without other securing means being necessary. As thus set, the turntable is prevented from rotating under the action of the driving motor by the brake 8<11>. At the predetermined time, the end 2<1> of the lever 2 moves downwards to free the pin 5 so that the arm 3, under the torsional action of the spring 7<11> transmitted through the member 9<1>, turns upon the screw 4. The member 8, integral with the member 9<1>, is thus free to rotate with its arm 8<1> and pin 8<11>, with considerable force, and carries the turntable 24 with it. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a further construction embodying similar principles in which a spiral spring enclosed in a semi-cylindrical chamber is adapted upon release from the tensioned condition to exert a pull upon a starting member which presses against a projection on the turntable, so to produce a starting torque. This subject-matter does not appear in the Specification as accepted.

Abstract: 465,112. Automatic guns. CESKOSLOVENSKA ZBROJOVKA AKCIOVA SPOLECNOST BRNO, and HOLEK, V. Oct. 28, 1935, No. 29728. [Class 92 (ii)] Relates to automatic guns'of the short-recoil type in which a catch member is released to permit forward movement of the locked barrel and breech block and cause firing to be effected before the end of said forward movement. According to the invention, the catch member 20 is controlled by an action slide 10 which moves relatively to both the gun casing 1 and the barrel 2, and co-operates directly with the tilting breech block 3 for locking and unlocking the breech, and after locking the breech and releasing the catch 20, acts directly on the firing-pin 5. The invention is shown applied to the automatic gun described in Specification 465,805 in which the action slide 10 is a continuation of a gas piston operated by tapped gases from the gun barrel. The Figure shows the position of parts at the end of the recoil, the barrel being shown arrested by the catch 20 on the gun casing which rises into the path of the barrel-shoulder 13 on being passed by a projection 23 on the slide. When the slide returns, its projection 9 closes and locks the breech and its projection 23 engages the inside of the catch 20 to release the barrel. Further forward movement of the slide causes the projection 9 to strike the firing-pin 5 before the barrel reaches its forward position.
