Title: Improvements in or relating to super-regenerative receivers
IPC: H03F3/02
Filed: 1940-06-25
Abstract: 542,147. Valve circuits for wireless reception. STANDARD TELEPHONES & CABLES, Ltd., and MONTGOMERY, W. A. June 25, 1940, No. 10860. [Class 40 (v)] In a super-regenerative receiver the quench frequency is made sufficiently low for the detector oscillation to build up to saturation value so that the detector has a logarithmic characteristic and the following low frequency amplifier has an exponential characteristic so as to compensate for the distortion. The Figure shows a triode detector V1 resistance capacity coupled to an amplifier V2 the grid bias of which is critically adjusted by potentiometer R5, R6, R7. The Specification gives a mathematical analysis to show that harmonic distortion is eliminated and that a small amount of amplitude distortion of the nature of volume expansion remains which is negligible for modulation below 70 per cent.

Abstract: 1293725 Removing Fe from Ti ores HYDROCARBON RESEARCH Inc 23 April 1971 [7 May 1970] 11037/71 Heading C1N Iron is removed from a titaniferous ore by passing H 2  which is substantially free from CO through a bed of the ore maintained at a temperature of 1400‹ F. or below, to reduce the iron fraction, leaching with dilute inorganic acid to dissolve out the iron and generate H 2 , separating the TiO 2  concentrate from the iron containing solution, and recycling the H 2  after scrubbing to prevent carry-over of acid. The ore is preferably ilmenite of particle size 20-325 mesh Tyler, and is fluidized by the H 2 . The reduction may be effected at a partial H 2  pressure of at least 150 p.s.i. and a total pressure of 180-220 p.s.i.g., and at a temperature of 1100-1400‹ F., such that at least 85% reduction to metallic Fe occurs. The ore may then be magnetically separated, and leached with 10- 30% H 2  SO 4  or HCl. The effluent gases from the reduction, containing unreacted H 2  and H 2 O vapour, may be passed in heat exchange with ingoing H 2 , then water-scrubbed, further cooled to condense out H 2 O, compressed, and recycled.

Abstract: 582,088. Wave guides. CORK, E. C., and MANIFOLD, M. BOWMAN-. Aug. 14, 1942, No. 11443. [Class 40 (v)] An angle or bond in a wave guide which would normally give rise to undesired secondary waves is prevented from so doing by arranging that forward travelling components of secondary waves set up at a plurality of planes tend to neutralize one another. In 'Fig. 1, where the change in direction of the guide is effected by a straight oblique section, the length L of this section is chosen according to a formula given in the Specification in terms of the wave-length within the guide of the desired E01 wave, and the wave-length of the undesired secondary H11 wave. When the guide is curved to effect change of direction, the radius of curvature and the resulting length of the curved section are chosen according to a similar formula. In Fig. 3, an obstruction such as a screwed plug S is placed at the mid-point of the bend, and further plugs may be inserted at the planes E, F at stated distances from the plug 5. Plugs may also be inserted in a direction perpendicular or oblique to the plane of the bend to suppress H21 waves. Alternatively, the diameter of the guide at the bend may be such that the H21 wave cannot be generated. Rings may be inserted in the straight portions of the guide at each end of the bend.
