Filed: 1924-08-20
Abstract: 220,948. Bauch Maschinenfabrik, E., and Wadenklee, A. Aug. 21, 1923, [Convention date]. W i n d i n g - machines; stopmotions; doffing-arrangements; thread-severing arrangements.- When the bobbin k, Fig. 3, in a yarn winding frame is fully wound, a rod c carried by the counter weight q pushes a member d upwardly and releases a pawl e, which permits a triangular lever h pivoted at f to turn into the position shown in Fig. 4, and at the same time, by means of a projection h<1>, to raise the friction clutch i and stop the spindle b. On turning, the lever h, through a connecting-rod o and levers p, p<1>, Fig. 2, operates a clutch t to connect a belt pulley r to a continuously rotating shaft s, and on rotation of the pulley r a weighted belt r<1> passing thereover is moved to draw the spindle bearing v downwards. When the bearing v is drawn downwards sufficiently for the spindle b to be completely withdrawn from the bobbin, the said bearing strikes a lever x, which had been set in an inclined position on the release of the member h by the pawl e. The lever x is thereby moved back to its original position, and in so moving releases the clutch t through the connecting-rod o<1> and the levers p, p<1>, thus removing the pull from the belt r<1> and permitting the return of the spindle b to its operative position under the action of the weight q. Simultaneously with its operation'of the lever x, the bearing v through a projection v<1> and a stop w moves a rod w<1>, which actuates a lever y on the bobbin-ejector y<1>, Fig. 6, and causes the finished bobbin to be thrown into a trough z. The lever y also actuates a thread-cutter j comprising a spring-controlled blade movable in a sleeve. A second lever h may be provided to act as a broken-end stopmotion.

Abstract: 459,535. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Tolson, W.A.; 110, Cuthbert Road, Westmont, New Jersey, U.S.A.) July 10, 1935, No. 19740. Convention date, July 27, 1934. [Classes 40 (iii) and 40 (v)] Deflecting oscillations are fed to the deflecting plates over a transformer having a high resonant frequency and preceded by a low pass filter having an upper cut-off below the resonant frequency of the transformer so that distortions 103, Fig. 6, due to the high frequency response of the transformer are eliminated. Received signals, demodulated at 23, Fig. 1, are fed in their entirety to the grid 7 of the cathode ray tube 3, and also to the valve 27 which is biassed to pass only the synchronizing impulses. The line synchroning impulses pass over condensers 29, 31 to a valve 39, connected as a blocking oscillator but biassed to cut-off, so that one impulse only is generated when a synchronizing impulse is applied to the grid. This valve produces large amplitude peaked impulses which trip a relaxation oscillator comprising condenser 77, charging resistance 79 and discharging valve 41. The saw-tooth oscillations are amplified by valves 43, 45 and applied to an auto-transformer 93. The resonant frequency of the transformer 93 produces distortions 103, Fig. 6, in the saw-tooth oscillations, and this is prevented by a low-pass filter 81, 83, 85 in the input of valve 45 which cuts off below the resonant frequency of the transformer 93. The transformer feeds an impedance 99 whose ends are connected to the deflecting plates 17 and whose mid-point is connected to a second anode 15. The line frequency synchronizing impulses pass over inductance 35 to control a valve 37 which operates similarly to the valve 39 and controls the relaxation oscillator 135, 137, to energize the deflecting coils 19.

Cellulose xanthates, processes for making filaments and films from; apparatus for making filaments and films.-In a process wherein artificial silk, films, &c. are made from viscose by coagulating the viscose in a bath containing inorganic salts or suitable organic coagulants and then treating the coagulated products in an acid bath, the two baths are arranged as separate compartments of a single container. In the apparatus shown the container 1 is divided by the partition e into two compartments A and B, which contain respectively the coagulant, for example a 30 per cent salt solution, and acid, for example 30 per cent sulphuric acid. The viscose is forced through nozzles a into the coagulants, which enters compartment A through pipe f and flows out through the overflow pipe g, and the coagulated filaments are passed through the acid, which enters compartment B through pipe f<1> and flows out through the overflow pipe g'. The filaments b on leaving the acid bath possess great strength, so that they can be led off without difficulty over thread guides h on to suitable winding devices d but they are preferably washed with warm water or steam shortly after leaving the acid bath. The process is particularly suitable for the production of very fine filaments. The Specification as open to inspection under Sect. 91 (3) (a) states that the partition is preferably interrupted adjacent the liquid level to allow passage of the filaments. This subjectmatter does not appear in the Specification as accepted.
