Patent GB-792725-A (GB)
Title: Methods and apparatus of scanning by electro-oscillographic means
IPC: G01J3/28
Filed: 1954-10-12
Abstract: 792,725. Recording-apparatus. NIELSEN, H. Oct. 12, 1954 [Oct. 20, 1953], No. 29412/54. Class 106 (4). [Also in Group XL (b)] In apparatus for producing on an oscillograph a curve representative of the light intensity along a spectrum, the signals representing the spectral intensity are recorded over a number of scanning cycles so that when the record is used to provide the oscillographic curve, long-term variations in intensity of the light source are eliminated. As shown, a spectrum is formed by a prism and lenses and projected on to the screen of an iconoscope which is repeatedly scanned by an electron beam 6 also deflected by the output of a time base oscillator 17. The iconoscope output is amplified at 7 and fed through an electronic switch 8 to one of a pair of recording heads 9, 10 and recorded on the magnetic surface of a drum 11. The rotation of the drum 11 is synchronized with the operation of the time base oscillator 17 by means of a mirror on the drum which directs a light pulse to photo-cell 15 once per drum revolution and so triggers the time base oscillator. Periodically the electronic switch 8 changes the recording head to " read " and uses its output to control the vertical deflection of a cathode-ray tube trace, the horizontal deflection being controlled by time base oscillator 17. The iconoscope scanning beam is deflected at high frequency at right-angles to its path along the trace (Fig. 2) producing an output as shown in Fig. 3c from which the low-frequency is removed (Fig. 4), .the high-frequency being then passed through a high-frequency detector to produce the lowfrequency signal curve (Fig. 5) which is independent of the scattered light, the intensity of which is shown in Fig. 3b.

Title: Improvements in the recovery of carbazole
IPC: B63B3/56
Filed: 1929-09-28
Abstract: Carbazole is recovered from tar fractions containing carbazole by treating the initial material with hydrogen or gases supplying hydrogen, at temperatures above 300 DEG  C. but below 550 DEG  C., and under pressure, preferably in the presence of catalysts such as the metals of the sixth group of the periodic system, or zinc, aluminium, silicon, manganese or their compounds.  The temperature and pressure should be such that the carbazol itself is not decomposed.  The carbazole may be obtained by cooling the product and filtering, or by distilling off the low boiling constituents. In an example, a mixture of anthracene residues and anthracene oil is treated with hydrogen under a pressure of 200 atmospheres at 440 DEG C., in the presence of a catalyst containing molybdenum, chromium and manganese.  The vapours leaving with the hydrogen are condensed and the carbazole filtered from the cool condensate.ALSO:Carbazole is recovered from tar fractions containing carbazole by treating the initial material with hydrogen, or gases supplying hydrogen, at temperatures above 300 DEG  C. but below 550 DEG  C., and under pressure, preferably in the presence of catalysts such as the metals of the sixth group of the periodic system, or zinc, aluminium, silicon, manganese or their compounds.

Title: Improvements in or relating to creels for textile machines
IPC: D02H1/00
Filed: 1966-07-01
Abstract: 1,103,129. Creels. HAMEL PROJEKTIERRUNGS UND VERWALTUNGS A.G. 1, July, 1966 [12 Aug., 1965], No. 29663/66. Heading D1J. . Each bobbin supporting spindle 2, in a creel frame 3, is provided with a spindle extension 2<SP>1</SP> projecting at least 100 mm. beyond the end of the bobbin, there being a thread guide 4 co-axial with each spindle such that the angle formed by a line connecting the outer end of an extension with the thread guide of an adjacent spindle is not less than 30‹. The purpose of this is to prevent a broken thread from one bobbin being caught up in the thread running off from another bobbin. As shown in Fig. 1 the thread from the central bobbin has fractured and dropped down so as to snarl with the thread 5 running off from the lowermost bobbin 1. During this period a few turns of thread from the middle bobbin are carried by the oblique pull on to the extension 2<SP>1</SP> of the spindle 2. The resulting friction on the thread extending between the lowermost thread guide 4 and the spindle extension 2<SP>1</SP> of the middle spindle 2 causes the thread extending therebetween to fracture. The surface of each extension may be roughened and/or profiled; a helical groove may be formed in said surface; a catch member may be formed at the free end of each extension, for example, an annular groove or an enlarged head.
