Title: Improvements in or relating to journal bearings
IPC: B61F17/20
Filed: 1929-05-17
Abstract: 329,836. Fletcher, G. H., and Associated Electrical Industries, Ltd. May 17,1929. Capillary - action lubricating; liquid level, maintaining.-In a horizontal journal bearing, lubricant is raised by a disc 13, Fig. 1, mounted on the shaft 12 from a drainage sump 5 to a reservoir 6, from which it passes through an aperture 8 to an absorbent pad 10 in contact with the shaft. The reservoir 6 is formed with an overflow sill 7, whereby the level therein is maintained constant, and the sump is provided with a filling aperture arranged at such a level as to prevent overfilling. As shown in Figs. 3 and 4, part of the lubricant raised by the disc 29 from the sump 33 passes into an auxiliary reservoir 27 arranged above the main reservoir 32. The lubricant level in the main reservoir, determined by overflow sills 38, is disposed slightly below the shaft 30. An aperture 35 in the side of the bearing sleeve 24, for receiving the absorbent pad (not shown), opens in the upper part of the reservoir 32, which extends to the top of the housing, where it is provided with a cap 36 for the introduction of the pad. The lower portion of the pad extends to near the bottom of the reservoir 32. The reservoir 27 is provided with an overflow sill 31 and is in communication with the reservoir 32 through an aperture 136 arranged slightly above the aperture 35. Thus the pad receives lubricant both from above and from below. A filling tube 48 arranged in an aperture 45 in the sump communicates with a conduit 47 opening above the normal level in the reservoir. When filling, lubricant is supplied through the tube 48 until it flows out through the aperture 45, which is afterwards closed by a plug 46. Specification 243,232 is referred to.

Abstract: 458,235. Valve circuits for wireless reception. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.- (Assignees of Morrison, H., Reichle, W. E., and Thayer, G. N.) June 5, 1936, No. 15818. Convention date, June 19, 1935. [Class 40 (v)] Muting during interstation tuning and when the carrier is suppressed is effected by a gas discharge tube 32 connected as an attenuating impedance in the audio-frequency path of the receiver. The direct current and low frequency output of the detector 15 is developed across the resistor 17, the low-frequency component being passed via condenser 19 to the amplifier 20. The direct current component is used (1) to give A.V.C. by grid bias control of the highfrequency amplifier 12, and (2) to control the impedance of a valve 30 in series with the tube 32. When no carrier is received, the impedance of the valve 30 is low, causing the tube 32 to ionize and thus shunt audio-frequency current from the amplifier 20 via condensers 34, 35. Receipt of a carrier causes impedance of valve 30 to rise, tube 32 to deionize, and consequently no shunting effect. A filter 31 may be provided to prevent transient direct current components across resistor 17, such as due to sparking of an internal-combustion engine from increasing impedance of valve 30. As an alternative, the tube 32 may be connected in series instead of in shunt to the audio-frequency path. Fig. 2 (not shown) discloses the circuit for a supersonic heterodyne receiver having delayed A.V.C. and embodying the muting feature of a gas discharge tube in shunt to the input circuit of the lowfrequency amplifier.
