Title: Horizontal deflection device for television apparatus
IPC: H03K4/62
Filed: 1963-07-01
Abstract: 1,028,774. Transistor sawtooth circuits. NIPPON COLUMBIA KABUSHIKI KAISHA. July 1, 1963 [July 9, 1962], No. 26006/63. Heading H3T. In a transistorized horizontal deflection circuit for television apparatus, deflection amplitude is stabilized against variations in load on the E.H.T. supply by the use of a damping diode in parallel with the output transistor and a supply boosting circuit in series with the output transistor. When the circuit shown is operated from a 6 volt supply, the supply boosting capacitor 4 becomes charged via diodes 3, 7 to 12 volts during the first part of each sweep and discharges via transistor 1 during the latter part thus providing a sawtooth current in horizontal deflection coils 5. It is shown that the use of both shunt and series diodes minimizes variations in sawtooth amplitude due to load changes on the E.H.T. supply obtained by rectifying the flyback pulses at diode 6. The series diode 7 may be selectively connected to different tappings on the output transformer 2 to permit operation on either 6 or 12 volt supplies. In Fig. 3 (not shown) diode 3 is connected directly across the transistor 1 and the deflection coils 5 are connected across the whole of the primary winding of transformer 2.

Title: Improvements in the production of polyacrylonitrile fibres and threads having high dyestuff affinity
Inventor: LIESEBERG FRIEDRICH
IPC: D01F6/18
Filed: 1958-08-20
Abstract: Solutions of polyacrylonitrile in dimethylformamide are spun through a jet in such a way that the extruded solutions are passed a short distance through air and then into a precipitating bath of dimethylformamide and water to form a tow, which is stretched in three successive baths comprising aqueous solutions of dimethylformamide of which the dimethylformamide concentration decreases in the approximate ratio <FORM:0881989/IV (a)/1> , the concentration in the first stretching bath being 2-20% by volume, the pH value of each of the stretching baths being maintained at a constant value within the range 5-7, the pH of the second bath being higher than that of the first and the pH of the third bath being higher than that of the second, the temperatures of the stretching baths being between room temperature and 100 DEG C., and the residence time of the tow in the three stretching baths being graded in the ratio of about 1: 1/4 :\ba1/4 , that in the first bath being from 1 to 4 seconds.  The precipitating bath preferably has a dimethylformamide content of 60 to 85% by volume.  In the example, a 20% by volume solution of polyacrylonitrile in dimethylformamide is spun through a jet built into a Thiele spinning funnel assembly beneath which is a precipitating bath in a channel.  The precipitating bath consists of aqueous dimethylformamide having a concentration of 74,2% by volume, a pH of 5,2 and a temperature of 16 DEG C.  When the spinning solution leaves the jet, it first passes through an air space of 5 mm. between the jet and the surface of the precipitating liquid.  The precipitating liquid, which is circulated through the funnel and the precipitating bath, embraces the threads and draws them through the funnel into the bath.  The column of precipitating liquid in the funnel is about 75 cm. in height.  The spun tow is then drawn through three successive stretching baths at 20 DEG C., 98 DEG C. and 98 DEG C. respectively and having dimethylformamide concentrations of 4,9, 2,2 and 0,05% by volume and pH values 6,0, 6,6 and 7,0.  The residence time of the tow in the baths is 1,25, 0,34 and 0,29 seconds respectively.  The total stretching ratio of the tow in the three baths is 1:5.  The fibres have a high dyestuff affinity and may be dyed with basic dyestuffs. Specification 663,500 is referred to.
