Abstract: 835,661. Axle-boxes; lubricating. UNITED STATES RUBBER CO. May 30, 1958 [Aug. 16, 1957], No. 17328/58. Class 12 (3). Lubricating means for a journal, e.g. in a railway vehicle journal box 10, comprises a lubricant resistant and resilient arch-shaped journal support body 23 which is preferably made of spongy neoprene rubber and straddles an oil reservoir in the bottom of the box 10. Longitudinal and lateral slots 24, 25, respectively, are provided in the body 23 to receive cross-shaped wicks 27, the streamers 28, 29 of which extend into the oil reservoir and deliver oil by capillary action to the journal 17. The latter, having a collar 18 and fillet 19, rotates relative to a partial bearing 20 held in position by a wedge 21. The body 23 is located in the box 10 by end lugs 26 which engage the innermost of two annular ribs 15 retaining a dust seal 16. The wicks 27, made e.g. of wool felt, are preferably provided with a series of staggered slits 32 and, in addition, or alternatively to the slits, with looped tufts of cotton cord. The upper faces of the centre portions of the wicks 27 may be singed or sanded to remove the fuzz and they could be made in one piece, the loops thus formed, below the body 23, being filled with additional wicking material. They are tied together by a cord 31 which is threaded through holes 30 in each streamer 29. A woven cotton pull-tab 34 is threaded through the central pair of slots 24 before the corresponding wick 27 is inserted, the ends of the tab being finally stitched together. In a modification, Fig. 4A, the underside of the body is hollowed out to save weight and receive an integral reinforcing rib-like structure 23a provided with slots to correspond with the slots 24, 25. Alternatively, the body 23 could be made hollow, being either inflated or filled with liquid.

Abstract: 1305753 Timing operation of machines LEAR SIEGLER Inc 13 April 1970 [10 July 1969] 17343/70 Heading G1J [Also in Division G3] An aircraft instrument has a digital time of day indicator 212-218, a long term elapsed time digital indicator 190-196, and a short term elapsed time dial type indicator comprising a sweep seconds hand 114 and a minute bug 112 which runs around the periphery of a dial 106. The instrument is governed by a crystal oscillator 130 in a thermostatically controlled oven and which drives synchronous motors 140, 142. The motor 140 drives, via a gear train 210, the time of day indicator 212-218 which is settable by a knob 224. The motor 140 also drives, via a gear train 186, the digital indicator 190-196 which may be used to log the flying time of the aircraft and may be manually interrupted and/or reset by a knob 200. The motor 142. drives the hand 114 and bug 112 which may be interrupted and/or reset by a knob 122. During this resetting, driver circuit 138 is driven, in reverse, at an increased speed from a reverse drive oscillator 153. Alternatively an increased speed drive may be derived from an early stage of binary counter 134. Accurate zeroing of the hand 114, and bug 112 is achieved by cam surfaces (165, 172) Fig.4 (not shown) and a coincident switching arrangement. In the zero position, the hand 114 lies between an hours belt 214 and a drum 216 of the time of day indicator. A power failure indicator 226 is provided.

[Class 13.] An acoustic horn is constituted by a plurality of sections arranged end to end some or all of which are made of metal and built up from a plurality of segmental castings having means formed integrally therewith whereby they can be secured to adjacent segmental portions and/or to adjacent sections. In the embodiment described two sound passages are provided each divided into sections 10, 11, 12 and 13, Fig. 2, and meeting in a common section 14 feeding a flared section 15, the latter being of wood and the other sections preferably being made of an aluminium alloy. Sections 10 and 11 are cast in a single piece and are circular in cross-section at the throat while gradually changing to a rectangular cross-section at the junction with section 12. Each of the sections 12, 13 and 14 is made up of segmental portions, their crosssections being shown in Figs. 3, 4 and 5 respectively. Thus the sections 12 comprise two castings 16, 17, the former having a flange 18 to which the latter can be secured. The sections 13 comprise two side portions 19 and top and bottom portions 20 provided with flanges 21. The sections 14 comprise two side portions 22 having flanges 24 and top and bottom portions 23. All the segmental portions are provided with end flanges 25 so that the sections may be bolted or riveted together to make up the complete sound conduit. Sections 10, 11 and 15 may also be similarly built up. The end sections may include two or more short conduits merging into one, to which sound reproducing instruments of different characteristics may be attached, and the horns preferably expand in cross-section according to an exponential law. In modifications, a rectangular conduit may be built up of two L-shaped members, (Fig. 6, not shown) or a hexagonal, circular or elliptical conduit may be built up of flat or curved plates provided with co-operating fixing flanges (Fig. 7, not shown). Distance bolts or bars may be provided between any two walls so shaped as to offer least impedance to the functioning of the air column. Alternatively or in addition the walls may be corrugated preferably longitudinally of the conduit, and they may be coated with sound absorbing material. When the horn is supported by resting the mouth portion on the floor &c. the remainder of the horn may be supported by posts adjustable in height through sockets 30, Fig. 2, carried by the sections 13.

Abstract: 624,342. Phase changing. GENERAL ELECTRIC CO., Ltd., HERWALD, N., and STOVE, J. P. July 4, 1947, No. 17695. [Class 38 (ii)] To obtain three-phase currents from a singlephase input, two thermionic amplifiers are arranged to produce single-phase outputs in quadrature which are applied to a transformer arrangement yielding three-phase currents. A single-phase source applied at terminals 5, 4 to a thermionic amplifier 5, gives a single-phase output from a transformer 13 in phase or phase opposition with the input, and applied to a tetrode 16 having an inductance 22 in its output circuit followed by resistance-capacity coupled amplifiers 24 ... 26 gives a 90 degrees phase-displaced output to a transformer 31. The transformers 13, 31 are Scott-connected to give a three-phase output at terminals 46, 47, 48. This may be applied through a transformer 50 to three-phase supply means for ripple control according to the frequency of the source at 3, 4. To compensate the effect of frequency changes on the inductance 22, the source voltage is applied to the grid circuit of a valve 33 having a condenser 38, the potential across which falls with frequency, and the output of the valve 33 after amplification and rectification is applied to a bias resistor 43 in the grid circuit of valve 16, which is of variable mu type.
