Title: High speed tubular spinning of fine viscose rayon yarn
IPC: D01F2/06
Filed: 1962-05-17
Abstract: 952,825. Spinning viscose. TEIKOKU JINZO KENSHI KABUSHIKI KAISHA. May 17, 1962 [May 23, 1961], No. 19071/62. Heading B5B. Viscose rayon yarn of less than 75 deniers is obtained by extruding viscose into a coagulating liquid which flows, together with the yarn resulting continuous filament and at substantially the same speed, through a tube of internal diameter 3-7 mm. throughout its entire length, winding up the yarn on a first rotating member disposed tangentially to the line of flow of coagulating liquid, and stretching the yarn, the regeneration value of which is not more than 20% at the time of being wound on said rotating member. The peripheral speed V of the rotating member is 150-300 m/min. and is such that V + 200 D is less than 410, where D (draft) is V divided by the speed of the viscose as it is extruded through the spinneret holes. The regeneration valve is defined as 1 - residual γ-value of the yarn/γ-value of viscose. The amount of stretching is preferably 20- 40%, between the first and a second rotating member. The concentration of sulphuric acid in the coagulating bath is preferably 1.7-2.6  times that of the total alkali in the viscose, and the concentration of salts in the bath is preferably 1.8-2.7 times that of the sulphuric acid. The 3-7 mm. diameter tube preferably ex. tends over the whole of the distance through which the yarn travels, and is preferably disposed at 45-90 degrees to the horizontal. The inlet end of the tube may be flared. The process makes possible the spinning of fine yarn of less than 75 deniers at high speed, e.g. above 200 m/minute.

Title: Improvements in and relating to cathode ray tube circuits
IPC: G01R13/30
Filed: 1948-07-16
Abstract: 646,253. Cathode - ray oscillographs. GENERAL ELECTRIC CO., Ltd., and KEMP, L. G. July 16, 1948, No. 19146. [Class 37] The width of the trace produced by a marker pulse is rendered narrow and independent of the duration of the pulse, at least over a substantial part of the height of the trace. On the working stroke a, Fig. 5, of the saw-tooth time base is superimposed a triangular wave b producing a resultant wave-form c having a horizontal portion CD indicating zero deflection in the direction of the time-base. The marker pulses are caused to appear during intervals CD and appear as lines of width equal to that of the luminous spot. A time base generator TB, Fig. 6, generating a saw-tooth waveform, is connected to one horizontal deflecting plate D1, while to the other plate D2 is connected a triangular wave generator TW generating a wave-form b, Fig. 5. A marker signal generator MS is connected to one of the vertical deflector plates D4, the other plate D3 being connected to a generator S of pulses to be examined, which may be time-modulated pulses in a pulse signalling system. The mean recurrence frequency of the pulses generated is determined by a master oscillator system SYN, which also synchronizes the time base generator TB, triangular wave generator TW, and marker signal generator MS. The marker pulses themselves may be used to provide a sufficiently close approach to bringing the beam to rest in the direction of the time base instead of using a separate triangular wave-form. A deflecting wave-form for producing a linear time base may be produced by integration of a rectangular wave-form by the procedure illustrated in Fig. 8. A pulse a of triangular form is differentiated, giving the waveform b,which is added to a rectangular waveform c and produces the waveform d. This is integrated to give a time base e of the same form as c, Fig. 5.

Abstract: 311,588. Vogel, J. L. F. July 4, 1928. Case-hardening. - Irons or steels containing molybdenum as an essential constituent and which may in addition contain other metals such as chromium or tungsten are hardened by a nitrogenization process, effected by heating them with a solid nitrogen compound which, at or below the temperature at which the nitrogenization of iron by nascent nitrogen occurs, decomposes in the presence of the metal, with or without contact with air, water or water vapour, generating the nascent nitrogen required for the process. The nitrogen compound may be any one of the substances urea, cyanides, cyanamides, sodium amide, hexamethlyene tetramine, potassium amide, naphthalene diamine, dicyandiamide, phenyl-hydrazine, acetamide and guanidine, or may be a mixture of such substances. It mav either be introduced into the heating receptacle together with the iron or steel or may be added after the latter has been heated. In order to avoid deformation of the articles treated, heating should not be carried to a temperature above 1100 ‹ C.
