Title: Improvements relating to radio navigation systems
IPC: G01S13/86
Filed: 1947-10-03
Abstract: 653,801. Radio direction-finding. COSSOR, Ltd., A. C., and ALLEN, A. Oct. 3, 1947, No. 26680. [Class 40 (vii)] In a direction-finding system for providing an indication on a cathode-ray tube of the bearing of a transmitter, a first receiver 6 develops a voltage dependent on the strength of signals received by a directional aerial system 5, 12, the voltage being applied to control the gain of a second receiver 7 fed from an omnidirectional aerial 8 so as to develop in the output a pulse corresponding to a minimum of the directional aerial system with respect to the transmitter, and the pulse being applied to trigger a narrow-pulse generator 9 to produce an indication on cathode-ray tube 4. The invention is shown as applied to a combined radar and direction-finding apparatus employing a common display in the form of a planposition indicator on which the directionfinder bearing appears as a brightened radial trace. The radar portion of the apparatus comprises a pulse transmitter 1 connected to a directional aerial 2, and a receiver 3 through which echo pulses are applied to the planposition display. The loop aerial 5 of the direc. tion-finder is carried on a shaft common with the radar aerial 2 and is rotated by motor 14. The minimum of the direction-finder aerial system is aligned with the maximum of the radar aerial. Receivers 6 and 7 have their tuning controls ganged so as to be tuned simultaneously to the same radio frequency by manual control 16 or motor 17. The tuning may be varied cyclically at a rate slow in comparison with the scanning of the aerials so as to display the bearings of all stations from which signals are received. The receivers may lock on to and remained tuned to any selected station. Specification 617,737 is referred to.

Patent GB-365085-A (GB)
Title: Improvements in or relating to processes for loading of natural silk
Filed: 1930-09-11
Abstract: Loading.--Natural silk fibres are loaded by treatment with acid solutions of loading metals in presence of quantities of neutral salts of alkalis, ammonium, magnesium, or organic amines sufficient to produce a salting out of the loading metals, and in presence of reagents such as phosphates which react to form the loading compounds in the same bath, and further treatment in a weakly alkaline bath containing no phosphates, the usual washing step between the baths being omitted.  In an example 15 per cent of the tin tetrachloride in a bath of 30 DEG  B<\>ae, of which the acidity is due to the tin tetrachloride with or without a small addition of free acid, is replaced by a similar amount of magnesium chloride, Glauber salt, common salt or Epsom salt and loading is effected by means of phosphate present in the same bath, whereafter the silk is passed through a weak alkaline solution, e.g. a 0,5 per cent ammonia solution, without intermediate washing.  Specified loading metal compounds are stannic and stannous chlorides and salts of zirconium or cerium with or without an addition of aluminium sulphate or other salts of aluminium or zinc.  Alternatively, stable inorganic or organic double compounds containing the loading metal and the neutral salt, such as sodium stannic hexaformate, tin ammonium chloride or the double chloride of quinoline and tin of the formula C9H8NSnCl3 may be used.  Preferably the loading bath is heated before the silk is introduced and is allowed to cool during the loading.  The silk may be subjected to a treatment with solutions of organic protective colloids such as glue, rubber, &c. before, during or after the loading to facilitate uniform dyeing and to impart a good feel.  Such a preliminary or subsequent treatment may be effected in presence of acids or acid salts, or, alternatively the silk may be subjected to a subsequent steaming.  To improve the durability of the silk and to control the degree of loading, the weakly alkaline bath may contain tanning materials and organic nitrogen-containing weakly basic compounds such as urea, thiourea, hydroxylamine, hexamethylenetetramine or derivatives thereof.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also (a) the loading of textile fibres in general, and specifically artificial silk, (b) the use of calcium chloride as a neutral salt for addition to the loading bath, (c) the use of water glass as an alternative to the phosphate, (d) the use of separate baths for the loading metal salts and the phosphates or other reagents forming the loading compounds, and (e) impregnation of the fibres with salts of aluminium or zinc.  This subject-matter does not appear in the Specification as accepted.

The mandrel 44 of a tube-extrusion machine, particularly intended for the production of blow-moulding parisons, is movable axially to vary the thickness of the extrudate by the actuation of a piston and cylinder arrangement 48, 49, movement of the piston being limited in the downstream direction by abutment between flanged nut 75 and an axially adjustable sleeve 72 and in the upstream direction by abutment between nut 75 and an axially adjustable stop 80. Sleeve 72, held against rotation by splines 73, is adjusted by rotation of a nut 76 and normally piston 49 is biased in the downstream direction by admission of oil to chamber 53 of cylinder 48 to follow the movements of sleeve 72. However, actuation of an electromagnetic valve 65, to connect chamber 54 of cylinder 48 to hydraulic line 67 via one-way valve 69 and accumulator 68, creates a pressure in chamber 54 sufficient to rapidly abut nut 75 against stop 80 with consequent attenuation of the extrudate, such attenuation being normally chosen at a point where the extrudate is to be severed. Nut 76 is adjusted by rotation of lever 79. Preferably such rotation is effected hydraulically in accordance with a predetermined programme. Oil from chamber 53 may flow upstream to form an oil bath for nut 76 and sleeve 72.
