Title: Improvements relating to the manufacture of cation exchangers
IPC: B01J39/24
Filed: 1951-03-20
Abstract: The process of the parent Specification is improved by employing an oxygen-containing gas containing "nitrous vapours," which phrase denotes any gas or vapour containing nitrogen in combination with oxygen such as nitric acid vapours or other gases containing oxides of nitrogen, particularly those containing nitric oxide.  The proportion of nitrous vapour used is preferably less than 10 per cent by volume of the oxidizing-gas mixture.  The heating period is reduced to from one-third to one-half of that previously needed.  The process may be made cyclic by regaining the nitrous vapours from the discharged reaction gases, e.g. by absorbing them in sulphuric acid, desorbing the sulphuric acid by heating, and supplying the liberated nitrous vapours to the oxygen-containing gas in which the solid carbonaceous material is heated.ALSO:The process of the parent Specification is improved by employing an oxygen-containing gas containing "nitrous vapours," which phrase denotes any gas or vapour containing p  nitrogen in combination with oxygen such as nitric acid vapours or other gases containing oxides of nitrogen, particularly those containing nitric oxide.

Title: Method of making mica-containing sheet
IPC: H01B3/04
Filed: 1960-02-25
Abstract: A mica sheet is made by forming an aqueous slurry of finely divided highly flaked mica and particulate water-insoluble binding material, applying the slurry to a forming screen, drawing water from the slurry through the screen to form a handleable sheet, and drying the sheet at least to a self-sustaining state.  The bonding material is present in a proportion of 6 to 30 parts by weight per 100 parts of mica, has a particle size greater than colloidal and substantially greater than the thickness of the mica flakes, is capable of flowing under temperatures below the melting point of mica so as to surround the mica and bond the flakes, and may be shellac.  The slurry may also include a wetting agent.  The sheet so made may subsequently be subjected to heat and pressure to render the particulate material flowable and to compact the sheet into a void-free material.  The products can be punched without delamination or chipping.

Abstract: 1,043,602. Transistor switching circuits; monitoring radio beacons. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 18, 1964 [Feb. 21, 1963], No. 6725/64. Headings H3T and H4L. [Also in Division H2] In a voltage-sensitive circuit, the conductivity of a Zener diode 11 is controlled by signals at input terminals 2, 3 and becomes conductive under certain conditions of input voltage so as to pass an auxiliary alternating voltage from transformer 11 to an amplifier 14 which operates a relay 20. As described, signals from a pulse code modulated radio-guidance beacon fed to terminals 2, 3 are rectified at 4 and charging capacitor 5 negatively. If the voltage across capacitor 5 is sufficiently negative, Zener diode 11 becomes conductive allowing 60 c/s. alternating voltage from transformer 10 to be amplified at 14, rectified at 17, 19 and used to energize a relay 20 so as to maintain contacts 21 open. The Zener diode 11 becomes non-conductive in the event of failure of the beacon so that contacts 21 become closed energizing an alarm 23. The time constant of the circuit 5, 6 is such that the alarm does not operate during spaces in the pulse modulation of the beacon. Various fail safe arrangements are described.

Title: Improvements in and relating to blast-conditioning devices for blast furnaces and the like
IPC: C21B9/16
Filed: 1964-02-19
Abstract: In a device for conditioning the blast blown into metallurgical installations, the blast is brought into contact with cold water to produce cooled, constant humidity blast.  The embodiment shown comprises a vertical fluid tight tank 1, divided into compartments by means of stainless steel sheets 3, 4 and 5; the lower two of which are perforated with a large number of stamped openings 6, the edges of which are raised.  Vertical tubes 7 and 8 connect adjacent compartments above and below each of the perforated sheets.  The upper sheet 5 comprises a plurality of passages 10 (of which one only is shown), in which are disposed fixed centrifuging screws 11. Water, supplied at a pressure of 4.5 Kg/sq.cm, enters the tank via a pipe 17, and is fed to sprayers 16, the jets from which overlap to cover the whole cross-section of the tank 1.  Water accumulates on the sheet 4, the thickness of the layer being limited by the extension above the sheet 4 of the vertical tube 7, which acts as an overflow. Similarly a layer of water then forms on the sheet 3, to which the tubes 8 act as an overflow, the water then collecting at the base of the tank and overflowing into a lower chamber 23, from where it is discharged through a valve 25 operated by a level detector 26. Air from a compressor enters the base of the tank through a pipe 2 and is regularly distributed by a perforated sheet 27 prior to passing through the perforations 6 formed in the sheets 3 and 4, and hence through the water layers 20, 19, thereupon.  The air then passes through the passages 10 and water droplets are projected by centrifugal force on to annular walls 12 surrounding the passages 10, by means of the centrifugal screws 11; the water flowing down the walls 12, collecting, and passing to the base of the tank via a pipe 14.  The resultant constant-humidity air is passed to the blast-using installation via a pipe 15. The gas leaves the compressor at a substantially higher temperature than the water and may be cooled prior to entering the tank; e.g. by circulating through a heat exchanger traversed by the cold air produced by the apparatus. <PICT:1048293/C6-C7/1>
