Title: Improvements in or relating to signal receivers
IPC: H04Q1/45
Filed: 1952-09-05
Abstract: 723,061. Voice-immunity circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Sept. 5, 1952 [Sept. 10, 1951], No. 22399/52. Class 40 (4). In an A.C. signal receiver in which the bias of a valve is controlled by opposed signal and guard voltages which are obtained in the anode circuit from a tuned circuit and a resistor, the component of the guard voltage due to the signal frequency is opposed by a further A.C. voltage derived from the tuned circuit so that the guard voltage is completely neutralized when a pure signal frequency only is received. As shown, incoming signals at transformer 21 are amplified at valve B2 and are applied to the control grid of a valve B1 as well as to an output circuit over a transformer 28. The receiver described is responsive to one or the other of two signalling frequencies which are separately detected in the anode circuit of B1 over tuned transformers 5 and 33, and after rectification at G1, G3 control the operation of a relay 3 or 24 by increasing the anode current of B1 or B2 respectively. A guard potential is established across a resistor 9 and is applied over transformers 11 and 44 in opposition to the segregated signal frequencies, rectification being effected by G2 and G4 respectively. Each guard circuit includes a winding 18, 42 of a tuned transformer in which the induced voltage opposes the component of the guard voltage of the same frequency and hence disables the appropriate guard when a single signal frequency only is received. The use of transformers 11 and 44 enables a transient disabling voltage to be induced in the guard circuits at the commencement of a signal pulse to avoid the guard voltage establishing more rapidly than the voltage from the tuned circuit. Since a rapid change in the operating condition of valve B2 would cause undesired voltage pulses to arise in the output circuit, the control of the valve is effected through a condenser 27 which is charged comparatively slowly at the commencement of a signal pulse through a resistor 45 and discharges at the end of the pulse through rectifier G5 and resistor 38. Neon tubes 8 and 36 are included in the tuned circuits to limit the anode current.

Abstract: 995,450. Photo-electric polarimeters. BODENSEEWERK PERKIN-ELMER & CO. G.m.b.H. June 13, 1962 [June 13, 1961], No. 22721/62. Heading G1A. The invention relates to a polarimeter which includes a polarizer, a further polarizer acting as an analyzer, and a radiation detector behind the analyzer wherein an optically active sample is inserted between the polarizer and the analyzer, and the polarizer is excited into rotary oscillations about its beam axis by magnetic means, the output signal of the detector is fed to phase sensitive balancing means causing a follow-up rotation of the analyzer with the rotation of the polarization plane due to the sample, characterized in that the polarizer is connected to a magnet rotor pivotally supported in the air gap of an A.C. excited electromagnet. In the embodiment shown light from a source S such as a mercury vapour lamp is fed through an oscillating polarizer P oscillating at 50 c/s, and from there through a sample PR to an analyzer A behind which is a photo-electric cell E which may be a photomultiplier connected through an amplifier V to a Ferraris motor M which controls the position of the analyzer A. With no sample in position and the polarization planes of the polarizer P and the analyzer A previously aligned at rest, the output signal of the photoelectric cell E will have twice the frequency of the oscillation of the polarizer P and will cause no rotation of the motor M since its exciting winding is fed from the same 50 c/s supply as the electromagnet (Figs. 1-5 not shown) oscillating the magnetic rotor connected to the polarizer P. With a rotation of the polarization plane due to a sample PR the detector signal obtains a Fourier component of the frequency of the polarizer oscillations (Figs. 7 and 8 not shown) which causes the motor to rotate to the right or left according to the direction of rotation of the polarization plane and through suitable gearing the analyzer is rotated until balancing is effected, the angle of rotation being indicated by a digital meter 2 driven with the analyzer. A filter wheel (Figs. 1 and 2 not shown) having several spectral filters of different transmission ranges any one of which may be inserted in the ray path of the apparatus, may be provided. Specification 875,278 is referred to.

Title: An improved process of and apparatus for the manufacture of phosphate fertilisers
IPC: C05B1/02
Filed: 1945-09-06
Abstract: <PICT:0623989/III/1> In producing solubilised phosphatic fertilisers, a mixture of sulphuric and nitric acids is fed into one end of and progressively traversed through the lower portion of a mixing chamber and the finely divided calcium phosphate is caused to fall through the chamber from a suitable height so that a continuous cloud of solid particles is produced above the reaction mass over at least a part of its length, while a thin continuous protective absorbent crust or skin is permanently maintained over the surface of the continuously intermixed reaction mass.  The crust reduces the release of nitrogenous vapour bubbles while the cloud p  absorbs and returns any such vapours which do escape and is partly solubilised.  As shown, the acid from tank 5 is fed to a U-shaped trough, divided into two portions 9 and 10 by a partition 8 having orifices 11, and provided with a screw mixer 2.  Calcium phosphate fed at 15 is distributed by an endless chain or belt device 13 fitted with scraper plates 14 which move the solid along a distributer plate 17 having a longitudinal opening so profiled that the delivery of solid is very small near the acid-delivery end of the apparatus, but increases to a maximum above the partition 8; such delivery may or may not continue a certain distance towards the discharge end 4 of the chamber as desired. Other fertilising agents containing e.g. nitrogen or potassium may be added to the raw materials or the product.

[Also in Group XXXIII] In a continuous flow internal combustion aircraft engine, in particular a ram-jet engine, an unapertured tubular wall or flame tube 3 is disposed within an outer tubular casing 1 which constitutes the aerodynamic supporting surface of an aircraft propelled by the engine, so as to define therebetween an annular passage P through which flows a gaseous stream cooler than the combustion gases produced within the flame tube. Fuel is supplied to the combustion zone C within the flame tube by means of annular injectors 2 disposed upstream of the flame tube. The passage P may either be of uniform or of varying width; in one embodiment the passage may be in the form of a diffuser either at the forward or at the rearward end or along the whole length of the passage. When used in supersonic aircraft the increase in cross-sectional area of the passage results in a reduction of pressure therein and so an increase in outward pressure on the flame tube. The invention is also applicable in the case of gas turbine jet engines.
