Title: Diversity receiving system
IPC: H04B7/08
Filed: 1955-11-25
Abstract: 792,124. Radio receiving systems. DAY, J. R. Nov. 25, 1955 [June 24, 1955], No. 33850/55. Class 40 (5). In a diversity receiving system for frequency modulated signals, a noise channel connected to the output of each receiver selects only noise components lying outside the intelligence band and applies them after rectification as a bias to a signal combining circuit so as to vary in the combining circuit the magnitude of the output from each receiver inversely in accordance with the magnitude of the noise components. Noise signals N1, N2 in the output of receivers 1 and 2, the amplitude of which varies inversely with the amplitude of the received signals are selected by high-pass filters 12, 22 cutting off at, say, 300 kc/s. and amplified at 13 and 23 to provide across resistors 14, 24 bias for combining tubes T1, T2 to which outputs S1+N1 and S2+N2 are respectively applied. The intelligence signals which are in phase are combined additively in the common anode or cathode load whilst the noise signals, the strongest of which is amplified the least and because they are uncorrelated are additive only as the root of the sum of the squares are each reduced, by the load of the other combining stage, i.e. A tube TM which is normally cut-off by the potential across resistor 49 in the common anode circuit of muting control tubes TM1, TM2 is provided to cut off tubes T1, T2, through the common cathode resistor 35, if, due to the signal falling below a predetermined level, the output is mainly noise. The tubes TM1, TM2 are also controlled by the bias across resistors 14, 24.

Patent GB-791887-A (GB)
Title: Method of de-oxidising metal surfaces
IPC: C23G1/08
Filed: 1955-11-29
Abstract: Oxide is removed from the surface of iron and steel articles by immersion in a hot solution consisting, apart from minor amounts of such substances as activators, of water, hydrochloric acid and ammonium chloride there being at least 10 gm. of the latter per 100 ml. of solution.  Preferably the acid concentration is between 16 and 37 per cent by weight of HCl, the temperature between 70 DEG  and 75 DEG C.; whilst the solution may be saturated with ammonium chloride. The treatment is applicable to carbon steels, "stainless" steels, molybdenum steels, tungsten steels, chromium steels, nickel steels, and chrome-vanadium steels.  The ammonium chloride apparently acts as inhibitor and also as passivator since the cleaned steel surface after washing shows little tendency to reoxidize immediately. Treated surfaces may be vapour-, chemical-, or electroplated.

Abstract: 817,673. Automatic steering control systems. ENGLISH ELECTRIC CO. Ltd. Dec. 2, 1955 [Dec. 3, 1954], No. 35144/54. Class 38 (4). [Also in Group XIX] In a guided missile control system, in which control is effected from the comparison of the actual and the predicted missile positions, random errors are introduced into the control system if the predictor and the integrating accelerometers, which measure the actual position, are started simultaneously. The present system places the accelerometers under the control of the predictor prior to the missile launching to prevent such errors. As shown, the accelerometer rotor 21 is rotated in accordance with the energization of stator 22. The latter is mechanically unbalanced relative to its axis A, A so that acceleration in a plane perpendicular to A, A will tend to cause a displacement of 22 about A, A which is detected at 25 and which controls the energization of 22 from control unit 23. Prior to acceleration measurements being taken in 21, 22, before missile takeoff, the accelerometer is given a predetermined control by means of 28, 30. Rotor 30 is coupled to 21 and is rotated by stator 28 energized in accordance with stored information from function generator 11. After launching, the accelerometer output, from 27, is compared, at 12, with the function signal from 11 and the resultant used to direct the missile.
