Filed: 1947-07-10
Abstract: 624,828. Generating combustion products under pressure. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. July 10, 1947, No. 18325. Convention date, July 18, 1946. [Class 51 (i)] A combustion chamber defined by annular walls 31, 32, Fig. 3, has an annular series of burners 37 directed downstream and primary air holes 40, 41. The burners are separated from the holes 40, 41 by two annular walls 43, 44 having perforations 46, 47. The stream of primary air past the perforations 46, 47 draws gases from the space between the walls 43, 44 and causes a counter-flow of gases from the combustion chamber into that space. The Specification, as open to inspection under Sect. 91, describes another form, Fig. 5 (Cancelled), in which the end wall 36 is imperforate and the primary air is admitted from the surrounding air space through holes 52, 53 into spaces behind annular walls 50, 51. The stream of air past the downstream edges of these walls draws gases out of the closed space surrounding the burners 37 and causes a counter-flow of gases into that space. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,141,531. Variable attenuators. WESTERN ELECTRIC CO. Inc. 27 April, 1966 [7 May, 1965], No. 18367/66. Heading H1W. A transmission-line ferroresonant attenuator comprises two ferroresonant elements spaced along the line and subject to a magnetic control field which produces equal increments of attenuation and equal, opposite increments of phase shift in the respective elements. As shown, each element 14 or 15 consists of two magnetic thin films supported between the central conductor 11 and the dielectric spacers 16 (of e.g. glass) of a symmetrical strip line 11, 12. Both elements are subject to the axial field of a common solenoid (not shown) which biases the elements to a condition of maximum attenuation corresponding to a maximum value of the imaginary film permeability component Á<SP>11</SP>. The corresponding value of the real component Á<SP>1</SP> is zero. Separate control windings (not shown) produce equal and opposite control fields in the respective elements 14, 15 whereby Á<SP>11</SP>, which determines attenuation, varies in equal amounts about its maximum value for each element and Á<SP>1</SP>, which determines phaseshift, varies in equal and opposite amounts about it zero position for the respective elements. Thus, the phase-shifts cancel out. The transmission line may be a coaxial line or a waveguide.

Filed: 1925-07-28
Abstract: 247,467. Eckardt, E. E. July 28, 1925. Retouching; negatives, producing by means other than photography.-Relates to the process of producing from a photographic negative either line drawings or prints with certain features emphasized in which the negative is rendered more or less impervious to actinic light, as by photographic treatment, painting, or dyeing, and the features which are to constitute the print or which are to be emphasized are scratched into the film in the form of continuous lines, stippling or hatching, or bare patches. According to the invention, the film, before scratching, is hardened in a bath containing stale hydrofluoric acid, and the negative, or the plate or film from which it is produced, may be coated with impervious material, such as glass dust mixed with sulphuric ether, which yields on drying a surface upon which the outlines of the features to be scratched in may be pencilled.
