Abstract: 292,544. Nelson, A. L. June 22, 1927, [Convention date]. Pistons; balancing laterally.-In a piston of the type having vertical webs 23 carrying the gudgeon-pin bosses and connected to a circular portion 25 of the skirt from which bearing portions 27 extend upwards, relatively inexpansible struts 10 extending between the bearing portions, casting strains are relieved by cutting converging slots 29 in one of the bearing portions from the edge of the skirt. The slots permit increase of the skirt diameter at right-angles to the gudgeon-pin axis and decrease in the direction of the gudgeon-pin axis. The struts 10 are embedded in the webs 23 and have inclined median flanges 11. The ends of the struts 'are also bent at an angle and are formed with vertical bars 30, Fig. 9, which are embedded in the bearing portions and constitute the point of attachment to the latter. The bars 30 are formed by cutting apertures 18 in the ends of the struts alternatively, more than one aperture 18 may be formed in each end, or the ends may be formed with T-shaped projections. Each strut is formed with a median notch 12, and with apertures 13 to increase binding with the metal of the webs 23. Holes 21 facilitate positioning during casting. The holes 13 may be replaced by elongated apertures or round holes. A strut may be formed as an open frame with their median portions 34, Fig. 8, and internal projections 35 to increase bonding with the webs 23. Specifications 268,399 and 304,250 are referred to.

Abstract: 675,952. Velocity modulation tubes. PHILCO CORPORATION. July 21, 1948 [Aug. 22, 1947], No. 19533/48. Class 39 (i). [Also in Group XL (c)] In a mixer circuit the electrons in a drift space of an electron tube are bunched at one of two frequencies, for example as a result of velocity modulation and the flow of electrons entering the space is interrupted at another frequency so that electrons flow only for a small part of the cycle, the required side-band energy being extracted from the electron stream leaving the drift space. The intensity of the electron stream leaving the cathode 9 is modulated by applying to the grid 11, which is biased beyond cut-off, a frequency-modulated LF. signal F, derived, for example, from the receiver at a radio relay station. A very high-frequency master oscillator 13 of frequency Fo is coupled to a first cavity resonator 2 to velocity modulate the electrons entering the drift space 4 and the desired side-band component which may be fonfi (where n is any integer) is selected by a second cavity resonator 3 and fed to the aerial through a lead 21. The tube may have a curved drift space in which case a magnetic field will be required to impart the necessary curvature to the electron stream and the intensity modulation of the beam may be effected by magnetic or mechanical means. Reference has been directed by the Comptroller to Specification 647,526.
