Title: The production of chlorine dioxide
IPC: C01B11/02
Filed: 1950-03-23
Abstract: Chlorine dioxide is produced by contacting a solid soluble chlorate, e.g. of an alkali or alkaline earth metal such as sodium, potassium, calcium, or lithium, in particulate form with nitrogen dioxide in the presence of moisture and a gaseous diluent, e.g. air, nitrogen, carbon dioxide, or oxygen, the surfaces of the chlorate particles being moistened with nitric acid prior to the beginning of the reaction.  This moistening may be effected either by treatment of the chlorate with say 10 per cent of 50 per cent acid directly or by treatment first with water and then with nitrogen dioxide to form nitric acid in situ.  The chlorate may contain say 10 per cent of an inert solid, e.g. metal silicates such as diatomaceous earth, clay or pumice, or refractory oxides such as silica.  The gaseous diluent should be at least say 95 per cent of the gas mixture, which should contain moisture to a relative humidity at least 30 per cent of the diluent gas at 25 DEG C.  Alternatively the nitrogen dioxide-diluent mixture may be produced by passing air through an electric arc. The reaction may be carried out in a series of towers successively advanced counter-current to the gas as the chlorate is progressively exhausted.  Specifications 595,528 and 663,239 are referred to.

Title: Improvements in or relating to control systems
IPC: H04N5/782
Filed: 1965-04-19
Abstract: 1,035,867. Automatic speed controls. AMPEX CORPORATION. April 19, 1965 [April 20,1964], No. 7746/65. Heading G3R. A magnetic tape recording and reproduction system for television comprises head drum 14 having transducers 15, 16, and driven by motor 18 through rubber disc 20. Tachometer reference pulses are provided by magnetic elements 37, 38, 39, associated with head 41, a head 44 recording the tachometer signals as timing control signals for the motor 18. The square wave signal from tachometer circuit 42 starts at a given phase relationship to the head drum position, binary divider circuit 51 and inhibit circuit 53 detecting the paired pulses which mark the start of each cycle, to initiate the reference wave in a positive-going direction. The tachometer signals control head switcher circuits 36, and are coupled into the servo system through circuit 58 or circuit 59. Circuit 58 permits selection during playback of the head which reproduces a given track, whilst circuit 59 sets the positions of vertical sync relative to the tape edge. In the "record" position, the vertical synchronizing source 49 is coupled to a pulse peak clipper 62 which provides uniform output pulses whether actuated by the vertical synchronizing or pulses reproduced from the control track. Multivibrator 63 acts as a binary divider for the vertical sync pulses but not for the reproduced timing pulses. Ramp generator 65 is coupled to error detector 67 in which the level of the ramp signal at the time that a pulse is provided by generator 69 determines the amplitude of the output signal. A compensation network 75 comprises a diode arrangement in series with capacitors, the diodes being short-circuited in the record mode. The capacitors reduce the time constant of the system and provide maximum bandwith for record timing accuracy. In the playback mode, the diode network presents a variable impedance to increase the time constant of the system for minor deviations. If a large error signal is present, the impedance of the diode network is reduced so that such errors are corrected rapidly. A clamping circuit 76 detects the absence of reference pulses and holds the error signal level at a predetermined point to prevent excessive head drum speed. The servo output signal is applied to oscillator 80 whose frequency is varied in accordance with the amplitude of the error signal. Divider 82 provides a square wave output through amplifier 83 to the motor 18.

Abstract: In a screw extruder for synthetic filaments, the working surface of the screw is coated with polytetrafluoroethylene, but the internal surface of the barrel is substantially free from the polymer.  The resulting difference between the coefficients of friction of the screw and barrel increases the efficiency; the rate and pressure of extrusion are increased and surging and uneven extrusion are reduced. The coating may be applied by using the screw to extrude polytetrafluoroethylene and afterwards transferring it to a barrel which has not been in contact with the material.  Preferably, however, a dispersion of polytetrafluoroethylene is applied to the screw and baked at a temperature above 327 DEG  C., the process being repeated if necessary to build up a thickness of, preferably, at least .001 inch.ALSO:In a screw extruder for plastic materials, such as polyhexamethylene adipamide, the working surface of the screw is coated with polytetrofluoroethylene, but the internal surface of the barrel is substantially free from polytetrafluoroethylene.

Patent GB-814779-A (GB)
Title: Vat-dyeing process
IPC: D06P1/673
Filed: 1957-03-11
Abstract: In the dyeing of natural or artificial protein fibres with vat dyestuff leuco esters, the fibres are first treated with an aqueous solution of bromic acid, whereby the final step of oxidizing with the customary developing solutions is rendered unnecessary.  The bromic acid solution may also contain a water-soluble bromate and may be replaced by an acidulated aqueous solution of a water-soluble bromate, e.g. an alkali metal or alkaline earth metal bromate, specified acidulating acids being sulphuric, hydrochloric and perchloric, although organic acids may be so-employed.  The bromic acid solution may also contain an acid-resisting wetting agent such as an alkali metal lauryl or oleyl sulphate.  Dyeing may be effected in an aqueous bath at a raised temperature or by padding.  In order to bring out the colour, an acid, e.g. acetic acid, may be added to the dyebath, or alternatively, the dyed material may be subjected to an acid treatment, or to dry heating or to steaming.  Enhanced effects may also be obtained by adding to the dyebath, or after-treating with, ferrous ammonium sulphate.  Numerous examples are given of the dyeing of wool, and in one case, peanut protein fibres are dyed.
