Abstract: <PICT:0708057/IV(a)/1> A continuous travelling tow of coagulated filaments obtained by spinning aqueous alkaline solutions of protein into sulphuric acid/sodium sulphate coagulating baths is relaxed under non-tensioning conditions in a solution containing not less than 220 g./l. of sodium sulphate, the relaxed filaments are treated at a temperature not exceeding 80 DEG C. in aqueous formaldehyde containing not less than 210 g./l. of sodium sulphate, and finally the tow is treated at a raised temperature in strongly acidified aqueous formaldehyde containing not less than 340 g./l. of sodium sulphate, not less than 15 g./l. of sodium chloride and not less than 200 g./l. of sulphuric acid.  The conditions are such that the travelling tow remains open and the filaments distinct, and the time required for insolubilization is between 1 and 30 minutes.  In the relaxing solution and the first formaldehyde bath the concentration of sodium sulphate preferably does not greatly exceed 220 g./l. and 210 g./l. respectively.  Similarly the concentrations of the reagents in the strongly acidified formaldehyde bath are preferably kept as close as possible to the minimum values given.  If desired another reagent producing a chloride ion may be used in this bath in a concentration equivalent to not less than 15 g./l. of sodium chloride.  This bath may be at a temperature between 70 DEG  and 98 DEG C.  As shown, a solution of groundnut globulin containing 20 per cent. globulin, 1.1 per cent. sodium hydroxide and 78.9 per cent. water is extruded into a coagulating bath containing 240 g./l. of sodium sulphate and 20 g./l. of sulphuric acid.  The coagulated tow 3 is stretched between godets 4 and 5 and then treated for 4 minutes with a solution containing 230 g./l. of sodium sulphate at pH 8.5 and 28 DEG -30 DEG C. in the trough of a ring trough 7 as described in Specification 623,460.  The treated tow is mangled between squeeze rolls 11 and further stretched between godets 12, 13.  It is then treated in a second ring-trough 16 with a solution containing 220 g./l. of sodium sulphate and 10 to 15 g./l. of formaldehyde at pH 5 and 55 DEG C.  The tow leaving trough 16 is passed between squeeze rolls 17, over a godet 18 and vertically downwards according to Specification 642,359 into a constant feed cone 19, where it is picked up by the insolubilizing liquid and carried through tube 21 into tube 23.  The insolubilizing liquid is an aqueous solution containing 340 g./l. of sodium sulphate, 40 g./l. of sodium chloride, 270 g./l. of sulphuric acid and 10 to 15 g./l. of formaldehyde.  It enters tube 21 at 90 DEG C. and leaves tube 23 at 85 DEG C.  The tow is removed from tube 23 by a godet 25. Specifications 597,497, 623,460 and 637,025 also are referred to.

Title: Improvements relating to television receivers
IPC: H04N3/20
Filed: 1938-07-19
Abstract: 506,112. Supply systems for vacuum and low-pressure discharge apparatas ; protective arrangements. BERRY, R. J. (Lorenz Akt.-Ges., C.) July 19, 1938, No. 21416. [Class 38 (iv)] In a television receiver a single source of H.T. potential 8 supplies the operating potentials for the cathode-ray tube and for the valves of time base and/or amplifying valves which are shunted by glow discharge tubes 3 for protection against excess voltage. A time base circuit consisting of a condenser 1 charged through a resistance 7 and discharged through a gridcontrolled gas discharge valve 2 is supplied direct from the anode voltage of the cathode-ray tube, output to the deflecting plates being taken from across the resistance 7. Only a small part of the charging characteristic of the condenser is utilised but the valve 2 is protected from excessive voltages which may arise by the shunt connection of a glow discharge tube 3 having a striking voltage higher than that of the valve 2. In the event of failure of the valve 2 the tube 3 takes on its timing function and prevents damage of the fluorescent screen by a stationary cathode-ray spot. Detector and amplifier stages of a television receiver may be supplied from the cathode-ray tube anode potential through coupling resistances and the valves are protected from excess voltages by shunt glow discharge tubes whose operating voltage is higher than the normal operating voltage of the circuit elements they protect.

Filed: 1974-05-15
Abstract: 1474607 Flash photography NIPPON KOGAKU KK 15 May 1974 [17 May 1973]  21612/74 Heading G2X A flash circuit is designed for recording data, such as the date or the like, on a film in addition to the scene which is to be photographed. The flash need not be energized every time the shutter is actuated to make an exposure. As shown, the power circuit 1 includes a D.C. source 10 and a flash capacitor 12. A voltage detector circuit 2 and trigger circuit 4 include a Zener diode 15 which acts as a switching element, a trigger capacitor 16, and a triggering transformer 17, the output of the latter being connected across the flash tube 5 via a synchroswitch 3. Switch 3 is closed by the action of shutter release. When the power switch 11 is closed, both capacitors 12 and 16 begin to charge up, and the voltage across the Zener diode also builds up. When the charge on capacitor 12 has reached a sufficient level to be discharged by the flash tube, the charge on capacitor 16 reaches the breakdown voltage of the Zener diode. This latter value can be adjusted as required by a  variable resitor 14. If switch 3 is now closed, this discharges trigger capacitor 16 through the transformer 17, which triggers the flash tube, so that it now discharges capacitor 12, thus producing a light flash. Figs. 4 and 5 (not shown) are various detail modifications of the circuit of Fig. 3. The charge-discharge cycle of flash capacitor 12 can be adjusted by altering the value of a resistor 13. If the minimum value of this cycle is longer than the time between successive operations of switch 3, e.g. with a motor-driven device for effecting continuous photography, then the flash will not operate every time a picture is taken, but can be set to flash at a predetermined interval, e.g. every five frames. The arrangement for photographing data on a limited area of the film frame can be seen in Fig. 2 (not shown).
