Title: Process of and apparatus for manufacturing seamless flexible tubes from cellulose solutions, particularly viscose
IPC: B29C48/09
Filed: 1928-12-07
Abstract: 304,754. Wolff & Co., and Weingand, R. Jan. 26, 1928, [Convention date]. Apparatus for making films.-Seamless flexible tubes of any desired length are prepared from cellulose solutions particularly viscose by allowing the cellulose solution to issue solely by its own weight and without the aid of extraneously applied pressure from an annular nozzle, directly into a. coagulating bath, whilst a precipitant liquid is introduced at the same time inside the nozzle and the tubular layer issuing therefrom. The spent portion of the precipitant inside the flexible tube is continuously removed by a syphon tube and suction device, the level of liquid inside the tube being preferably maintained at the same level as or somewhat higher than that of the external coagulating bath. In the form of apparatus shown in the Figure, the cellulose solution, such as viscose, flows solely by its own weight direct from the annular nozzle 1 into the precipitating bath 2 as a cylindrical layer 3. The tube 4, which serves to admit the precipitated liquid into the interior of the flexible tube 3 in course of formation, is provided with a regulating valve 5 and projecting through the nozzle 1, which may dip slightly into the precipitation bath. The spent portion of the precipitant liquid is continuously carried off through the syphon 6, which dips at one end only a short distance below the surface of the interior precipitant liquid and at the other end dips into the precipitation bath 2, from which the spent precipitant can be run off through the overflow 7. The supply of the precipitant liquid to the interior of the tube can be regulated by the valve 5, so that its renewal always keeps pace with the consumption, the rate of which depends upon the character of the cellulose solution, the working speed and the dimensions of the flexible tube. Uniformity of the flexible tube is maintained by the equality of pressure continuously maintained between the exterior and interior precipitant liquid by the syphon 6 and the tendency of the tube to contract may be counteracted by a positive pressure generated, for example, by adjusting the interior precipitant to a higher level than that of the exterior precipitation bath. A heavy longitudinal tension can be applied to the tube during formation in order to control the thickness of the tube and the whole process can be carried out in a continuous manner up to the drying stage by transferring the tube by means of rollers 8 and 9 from the bath 2 for further treatment in the usual washing, bleaching, desulphurizing, dyeing and plasticizing baths.

Title: Means for operating the hammers of pianos
IPC: G10C3/16
Filed: 1920-12-29
Abstract: 158,230. Smulders, C. Dec. 29, 1920. Pianoforte actions.- In means for operating the hammers of a piano comprising a pivoted jack engaging the hammer butt and adapted to have a sliding movement in relation thereto, the jack remains in its normal position relatively to the jacklever during the whole of the striking movement. In the construction shown as applied to a grand pianoforte in Fig. 1, the jack c, pivoted at d to the key-lever a and lightly counterbalanced or spring-held on an arm e which also limits its movement, has two surfaces g, h, on the former of which a heel l on the hammer j normally rests. During the release movement of the key and consequent fall of the hammer, the heel l rests on the lower surface h, from which it rebounds during repetition action. A roller t reduces friction. In the application to an upright piano, Fig. 3, the jack c is pivotally mounted on a lever p pivoted at a fixed point q. The Specification as open to inspection under Sect. 91 (3) (a) states that the jack c may be fixed upon the key a and the heel l jointed to the hammer j. This subject-matter does not appear in the Specification as accepted.

[Also in Division F2] In a fluid thrust bearing of an extruder, fluid is supplied to a gap between an end of a thrust screw 42 and end member 56 by rotation of screw 42 in the bore 41 of barrel 40. The fluid returns to the other end of the bore 41 through passage 60. A roller bearing 58 takes the thrust at low speeds of the screw 42. In Fig. 2 an extruder has a pair of extruder screws in a barrel 17 each feeding plastics material to a die 20. Each extruder screw is connected with a respective thrust screw in barrel 40, the connected screws being coaxial but having threads of the opposite hand. The axial thrust on the extruder screws during operation is balanced by that on the thrust screws produced at the bearing. The temperature of the bearing fluid is controlled by a heating or cooling fluid flowing through a jacket around barrel 40. The bearing fluid temperature may be controlled by the speed of the extruder screws.

IPC: G01L1/12
Filed: 1958-11-13
Abstract: 925,172. Magnetic amplifiers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 26, 1959 [Nov. 13, 1958], No. 36569/58. Class 40 (9). [Also in Groups XXX and XXXVI] In a system for sensing the magnitude of a load on a haulage plant, a haulage rope is made of magnetostrictive material and is electromagnetically coupled to a sensing circuit which produces a signal corresponding to the load magnitude. The rope may form the core of a magnetic amplifier having a polarizing winding energized with direct current to produce an assymetrical B-H curve. Stress variations in the rope then cause flux variations which generate a control signal in an output winding connected to an alternating current source. Such signals from two amplifiers associated with two rope sections can be combined to produce a resultant signal.
