Abstract: 278,922. Craven, A. B., and Yorkshire Dyeware & Chemical Co., Ltd. Jan. 1, 1927. Resins.-A solid resin is made from the semifluid resin extracted from crude gutta-percha or balata, by treating it with air at an elevated temperature to effect oxidation. A small proportion of siccative may be present, and about ¢ per cent of lime may be added before oxidation to neutralize free acids. The semi-fluid resin is usually extracted from the balata &c. by solvent action, and the process may be effected in an oxidizer of known type, comprising a horizontal cylinder having an agitator, and through which air is blown. The cylinder is steam jacketed. A charge of semi-fluid resin is introduced, with the' optional addition of 1 per cent of manganese resinabe, and heated to 80‹ C. Air is blown in and the agitator started. The temperature is raised to 100‹ C. after 4 hours and after 10 hours the' charge is run out, when it solidifies to an ambercoloured brittle resin.

Title: Impeder for production of intermediate frequency resistance welded tube
Inventor: SAKAMOTO MASATOSHI
IPC: B23K13/08
Filed: 1995-01-04
Abstract: PURPOSE: Not to be eroded as taking higher input voltage so as to increase welding speed and improve productivity by replacing part of a silicon steel sheet right under a work coil with a ferrite core. CONSTITUTION: An impeder 4A is constructed so that the length L part of a laminated silicon steel sheet 9 positioned at the upper side of an impeder axial core 8 right under a work coil 2 is replaced with a ferrite core 10. Thus, the silicon steel sheet 9 at the upper side of impeder axial core 8 is divided into 9a, 9b. Why the inserting position of ferrite core 10 is right under the work coil is that the magnetic flux generated from the work coil 2 is made to maximum right thereunder, further, the inserting position is the position corresponding to the open seam part of skelp 1 and the magnetic flux is directly acted on the impeder core material, therefore the position is replaced with the ferrite core 10. By this method, the input power, that is, input voltage can be made to higher.

Abstract: 864,964. Valve amplifying circuits. TESLA NARODNI-PODNIK. Jan. 2, 1959, No. 201/59. Class 40(6) A push-pull amplifier of the type in which the signal to be amplified is caused to widthmodulate a train of rectangular pulses comprises output valves 1, 2 Fig. 1, each shunted by a "recuperative" diode 3, 4 respectively. The anodes of the diodes 3, 4 are connected to the anodes of the respective output valves and their cathodes to H.T.+, the arrangement feeding a push-pull audio-frequency output transformer 9 via pulsefrequency chokes 5, 6 and by-pass condensers 7, 8. The arrangement is such that the valves 1, 2 are alternately energised during the respective positive and negative half-cycles of the signal to be amplified, while the action of the chokes 5, 6 is such that each of the diodes 3, 4 becomes conductive at the end of each rectangular pulse, when the corresponding output valve 1, 2 respectively is driven to cut-off. In a modification (Fig. 3, not shown) each of the diodes is replaced by a triode comprising a grid-controlled rectifier with its grid driven from the opposite side of the output transformer. In a further modification tetrodes 3, 4, Fig. 4, are used, the grids of which are connected to tappings on the opposite sides of the output transformer 9 via grid-current limiting resistors 11, 12 respectively. The screen-grids are connected to further tappings on the opposite sides of the transformer. The grids are also connected via condensers 13, 14 to tappings on the pulse-frequency chokes 5, 6 respectively, in order to limit the grid drive when the anode potential of either tetrode 3, 4 is low and so keep the screen-grid dissipation within safe limits.
