Title: Improvements in frequency discrimination systems
IPC: H04N1/00
Filed: 1943-09-28
Abstract: 580,968. Frequency modulation. PRESS WIRELESS, Inc. Sept. 28, 1943, No. 15905. Convention date, Sept. 9, 1942. [Classes 40 (iii) and 40 (v)] In a frequency-modulated signalling system, the discriminator of the receiving-circuit is designed to give a linear amplitude-frequency characteristic over a frequency range which is at least twice as wide as the range employed for the signal transmission, the object being to reduce distortion due to interference and noise effects. As shown in Fig. 8, applied to a radio picture transmission system employing audiotone modulation, the variable tone at the output of the radio receiver 41 is passed through a band-pass filter 42 and a limiter 43 to the frequency discriminator 44 comprising a network of resistances, condensers and inductances, whose dimensions are stated by way of example in the Specification. The filter is designed to give a linear frequency-amplitude characteristic over a range A-B which is more than twice the range CD employed by the signals, as shown in Fig. 4. The output of the discriminator is rectified at 53 and passes to the utilization device 55 through a low-pass filter 54. The invention is also applicable to systems in which a radio-frequency carrier current is modulated in frequency by any signal (Fig. 5, not shown) ; and to radio telegraphy systems in which different carrier frequencies are used for marks and spaces (Fig. 7, not shown). Specifications 537,689 and 537,689 are referred to.

Title: Sighting-device comprising two optical systems and a radiation sensitive detector
IPC: G01S3/783
Filed: 1970-04-03
Abstract: 1307579 Photo-electric apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 April 1970 [4 April 1969] 15967/70 Heading G1A [Also in Division H4] A device for sighting a distant radiation source comprises a radiation detector and two optical systems each comprising an optical modulator and a lens forming an image of the source on the detector wherein between the lenses and the detector is mounted on auxilary radiation source and the lenses form a catadioptric system for forming an image of said auxiliary source on said detector. In a horizon sensor on a satellite having two sighting devices (E-W and N-S), two infra-red images of the Earth are formed on bolometer 5 by germanium lenses 11, 21. Semi-conductor modulators 17, 27 are modulated in an inverse phase relationship to each other such that when the device is accurately pointed, the images cancel providing zero A. C. output. Due to asymmetry in the two systems there may be a small A.C. output when the device is correctly pointed. To obviate this the plane surfaces only of the lenses are treated to make them non-reflecting thus forming from the curved surfaces effective mirrors to radiation from a heated metal plate 4. The mirrors form images of the source on the detector. By adjusting screen 6 to vary the relative amounts of radiation reflected through the two modulators 17, 27, the zero error can be corrected. In an alternative embodiment two independently variable sources are provided, Fig. 1 (not shown).

Title: Electron discharge device
IPC: H01T14/00
Filed: 1942-11-12
Abstract: 601,206. Generators. FORMAN, J. Nov. 12, 1942, No. 16030. [Class 40 (vi)] [Also in Group XL (a)] An " electron-ion flame," a visible discharge from a conducting electrode having the appearance of a flame of burning gas, is produced by so connecting the conductor to a source of electric oscillations of sufficiently high frequency that it forms part of a resonant circuit developing high peak potentials at the part where the " flame " is to appear. It is stated that the phenomenon is probably due to direct excitation of molecules in the atmosphere by electrons drawn off by field emission from the electrode. The necessary high potential gradient is maintained by a space charge of positive ions built up in the region of the electrode during successive cycles, and the frequency of the oscillations and minimum pressure of the surrounding atmosphere must be so correlated that the electrodes go negative again during the lifetime (10<-8> seconds or less) of the positive ions created during the preceding negative halfcycle ; these ions may thus be re-attracted to the electrode and form a close space charge round it. For air, the minimum pressure is 200 mm. and the frequency must exceed 100 megacycles. The discharge may be initiated by bringing up another conductor, by making the electrode thermionically emissive (it may be self-heating) or by ionizing agents such as gas flames, alpha-, gamma- or X-rays. Various circuits using two- and four-segment magnetrons are described ; for example, two quarter-wavelength electrodes 17, 18, Fig. 1, are mounted at a suitable point in a transmission line 13, 14 connected at one end to magnetron anodes 3 ... 6 and terminated at the other end by the electrolytic bridge described in Specification 601,207. Various different modes of oscillation are possible and these result in either separate flames on each electrode, a flame connecting them, or a mixture of the two, Figs. 5-7 (not shown). Triodes or velocitymodulated tubes may also be used for generating the required oscillations. Specification 601,208 also is referred to. Reference has been directed by the Comptroller to Comptes Rendus (Doklady) de l'Academie des Sciences de l'Urss, Volume XVI, No. 1 (1937, pages 41, 42 and 43).

Title: Greases containing soaps of dihydroxy stearic acid
Filed: 1954-06-02
Abstract: A form of 9,10-dihydroxystearic acid which has a melting-point within the range of about 260-265 DEG  F., instead of the normal 190-200 DEG F., is produced by oxidizing oleic acid with potassium permanganate at about 30-35 DEG  F., or by oxidizing elaidic acid with performic acid at about 114 DEG  F.  In an example, an aqueous solution of sodium oleate containing potassium hydroxide is mixed with an aqueous solution of potassium permanganate and mixing is continued at 35 DEG F. for 30 minutes.  Sodium sulphite and concentrated hydrochloric acid is then added, whereupon the high-melting form of 9,10-dihydroxystearic acid separates as a solid from the aqueous layer.  It is filtered, washed and recrystallized from ethyl alcohol.ALSO:A lubricating grease having good water resistance and a high dropping point comprises a lubricating oil thickened with a metal soap of the form of 9, 10-dihydroxystearic acid which melts at about 260-265 DEG F.  This form may be produced by oxidizing elaidic acid with performic acid at about 114 DEG F., or by oxidizing oleic acid with potassium permanganate at about 30-35 DEG F. in a mildly alkaline aqueous medium containing a low concentration of reactants. The lubricating oil may be mineral oil, a hydrocarbon polymer, a di-ester (e.g. di-2-ethylhexyl sebacate) or a complex ester (e.g. one prepared from a dibasic acid, a glycol and a monobasic acid.  Instead of metal soaps of the 9, 10-dihydroxy-stearic acid above, soap-salt complexes of these soaps with metal salts of 11-C5 carboxylic acids may be employed.  Examples of these carboxylic acids are formic, acetic, propionic, butyric, valeric, furoic and acrylic acids. Metal bases suitable for the formation of the soaps and soap-salt complexes include the hydroxides of aluminium, alkali metals such as lithium, sodium and potassium, and alkaline earth metals such as calcium and barium.  The soaps and soap-salt complexes may be preformed or prepared in situ in the lubricating oil.  Additional ingredients such as anti-oxidants (e.g. amines) and extreme pressure agents (e.g. containing sulphur, halogen and/or phosphorous) may be incorporated in the lubricating grease.  In the examples, the preparation of lubricating greases containing mineral lubricating oil and the calcium, calcium-lithium or lithium soaps of the 9, 10-dihydroxystearic acid is described. For comparison purposes, the preparation of similar greases, employing ordinary 9, 10-dihydroxy-stearic acid or 12-hydroxy-stearic acid is described.
