Title: Improvements in or relating to electric frequency coincidence indicators
IPC: G01R23/00
Filed: 1945-05-30
Abstract: 628,245. Frequency measurements. PHILCO RADIO & TELEVISION CORPORATION. May 30, 1945, No. 13560. Convention date, May 30, 1944. [Class 37] In calibrating a variable-frequency oscillator against a standard oscillator, the zero beat frequency is determined by producing two beat frequencies having a phase difference of 90 degrees, both beat frequencies being changed to variable amplitude signals which are applied to non-linear circuits whose outputs are added to produce a wave having maximum amplitude at zero beat frequency. The output of the variable frequency oscillator 8 is heterodyned with local oscillations from a source 4 to produce an intermediate frequency which is amplified at 10 and tripled and limited in amplitude at 11; to ensure constancy of the intermediate frequency an automatic retroactive circuit 14, 15 may be employed, and constancy of amplitude may be obtained by A.V.C. The standard oscillator 1, 2, produces a series of fixed frequencies, and the appropriate frequency is mixed with oscillations from 4 to produce an intermediate frequency which is tripled and limited at 6. The two intermediate frequencies are mixed at 7, while the output from 11 is given a 90 degrees phase shift at 12 and mixed with the output from 6 at 13. The mixed intermediate frequencies 'are integrated (or differentiated) at 16, 20, phase inverted at 17, 21, applied to square law rectifiers at 18, 22 and mixed at 19, whose output is a maximum at zero beat frequency. The output of 19 produces a pulse at 23 which at its maximum actuates a blocking oscillator 24 to energize a lamp 25 which illuminates the scale of the variable frequency oscillator 8 to produce a photographic record on a camera 25. The pulse from 24 is also applied over inverter 26 and amplifier 27 to step on the film in the camera 28. Specifications 628,246, [Group XIX], and 628,312 are referred to.

Patent GB-834561-A (GB)
Title: Improvements in or relating to hollow bodies or containers and methods of making thesame
IPC: C23C18/36
Filed: 1956-05-03
Abstract: A hollow body is provided with a coating consisting of a nickel-phosphorus alloy containing 6-12% phosphorus by chemical deposition from a plating solution of the nickel cation-hypophosphite anion type, and is then heated at a temperature of 100 DEG -1100 DEG C.  The body, which may be a tank, railway tank wagon, pipe, drum or barrel and which may be coated on its interior or exterior, must be formed of a catalytic material (of which many examples are given). Interior coating may be effected by rotating the body on its longitudinal axis and circulating plating solution therethrough. Preferred plating solutions are those containing lactic acid and propionic acid or salts thereof.  The heat-treatment operation, which changes the alloy structure and which may anneal the body itself, is preferably performed in an inert atmosphere, e.g. nitrogen, or in a reducing atmosphere, e.g. cracked ammonia, with the body being rotated on its longitudinal axis.  After heat-treatment, the body is cooled gradually to 200 DEG C. and then air-cooled to ambient temperature.  Three heat-treatment temperature ranges are disclosed (the first two effecting a hardening of the coating and the third effecting an increase in its magnetic characteristics and electrical conductivity), viz. (a) 100 DEG C. to below 400 DEG C., (b) 400 DEG C. to below the melting point, and (c) above the melting point to 1100 DEG C.  After the coating has been heated in range (c) and then solidified, a further coating of nickel-phosphorus alloy may be deposited.  Reference has been directed by the Comptroller to Specification 785,693.
