Abstract: 617,913. Tuning radio apparatus. GENERAL ELECTRIC CO., Ltd., ASPIN, J. J. E., and HARRIS, E. S. May 27, 1946, No. 16004. [Class 40 (i)] [Also in Group XXXVII] In a push-button tuned radio receiver or transmitter in which each of one or more circuits is tuned by a component moved by a solenoid, the position of each tuning element is determined by the preselected setting of one of a number of adjustable members carried by a disc which, upon depression of a push-button, is rotated into position corresponding to that push-button. When one of the push-buttons P1-P12 is depressed, all the fixed contacts 20 of a selector switch except that corresponding to the depressed button are energized, and, unless the set is already correctly tuned, with wiper 16 on the dead contact, solenoid 7 is energized. This pulls to the left (Fig. 1) a magnetic core carrying on a flat self-aligning spring 4 ferromagnetic cores 5, 6 of inductances 1, 2 in the circuits to be tuned until switch 10 is closed. Solenoid 21 of a self-interrupting pawl - and - ratchet mechanism (see Group XXXVII), is energized and the mechanism steps round wiper 16 and a disc 12 carrying stops 30, 31 until wiper 16 reaches the dead contact when it stops, solenoids 21, 7 being de-energized. The cores 5, 6 are then moved to the right by spring 11 until prevented by those stops 30, 31 of appropriate length for the tuning corresponding to the selected pushbutton which have been brought into position by the self-interrupting mechanism. Pivoted arms with coil springs may replace the flat spring 4. Inductances 1, 2 and movable cores 5, 6 may be replaced by variable condensers.

Patent GB-876711-A (GB)
Title: An improved manufacture of inorganic thiocyanates
Inventor: FIELD JOHN EDWARD
IPC: C01C3/20
Filed: 1959-05-14
Abstract: Thiocyanates are prepared by reacting thiocyanic acid, dissolved in an inert substantially water-immiscible liquid, with a metal, an oxide, or a hydroxide, especially sodium, calcium, and barium hydroxides.  The water-immiscible liquid is preferably an ether, for example diethyl ether and especially di-isopropyl ether.  Benzene, chloroform, higher molecular weight alcohols, for example amyl alcohol, and higher molecular weight amines are also referred to. Mixtures of solvents, especially containing higher molecular weight amines and inert hydrocarbons, e.g. benzene, may also be used.  The metal, oxide, or hydroxide may be supplied to the reaction as a solution or a suspension, or in the form of a solid bed, through which the acid may percolate.  A solvent for the thiocyanate may flow through the bed simultaneously or subsequently to recover the thiocyanate.  The thiocyanic acid solution may be obtained by reacting a thiocyanate salt, e.g. the sodium or ammonium salt, with an aqueous strong acid, e.g. sulphuric acid, in the presence of the water-immiscible liquid, which extracts the acid as formed.  The process may be applied to the regeneration of the concentrated thiocyanate solutions employed in acrylic fibre production.  Iron may be removed from the thiocyanic acid solution by passing it through an anion exchange resin, e.g. a sulphonated polystyrene divinyl benzene copolymer, which may be regenerated by sulphuric acid.  In an example, a contaminated sodium thiocyanate solution is passed together with sulphuric acid in countercurrent to di-isopropyl ether. The ether, now containing thiocyanic acid, is passed through an ion exchanger to remove iron, and is then reacted with sodium hydroxide solution to give a pure sodium thiocyanate solution and ether, which latter is recycled.
