Title: Improvements in or relating to Lubrication Systems for a Universal Joint.
IPC: F16D3/38
Filed: 1968-07-29
Abstract: 1,170,214. Universal joints; lubricating; valves. DANA CORP. 29 July, 1968, No. 36146/68. Headings F2A, F2U and F2V. The usual lubricant feed from a central reservoir 40 through radially directed ducts 38 of an intermediate cross member 12 to the trunnion needle roller bearings 24 of a Hooke's type joint is controlled by one-way valves 46 located in enlarged bores of the ducts 38 in the cross member trunnions 14 such that lubricant supplied via a nipple 44, or centrifugally fed from the reservoir 40 in service, to the needle bearings 24 is prevented from inwardly returning, e.g. draining back to the central reservoir when the joint is stationary, e.g. with one of the cross trunnion arms in a vertical position, whereby inadvertant leakage of any of the liquid content of the lubricant, which would render the lubricant at the bearing solid and useless, from the radially outer end of the trunnion bearings back to the centre region is prevented. Each one-way valve is formed as an elastomeric thimble tightly fitted at its outer end in the enlarged trunnion bore 'A' and having at its inner end an inverted cone 50 cut at its rounded apex in a cross-slit 52 to form lips 53, the lips opening outward to allow radially outward lubricant feed to the bearings but immediately self-closing to prevent inward return thereof.

Abstract: 1,105,486. Frequency changing. L. E. SQUIRE. 7 Dec., 1964 [18 Sept., 1963], No. 36689/63. Heading H2F. Poly-phase third harmonic currents are generated in a circuit comprising two threephase transformers whose primaries, which are connected in parallel to a supply, are so arranged that the fluxes in the cores are displaced by 30 degrees (or an odd multiple thereof) if two phase third harmonic output is required, or by 40 degrees (or a multiple thereof) if three phase output is required, and the secondary windings of each transformer are connected is open delta so that the third harmonic voltages are added and the fundamental voltages cancel. Alternatively, to obtain a three phase output, the two phase arrangement above may be used with the secondaries in Scott connection to give three phases. The ninth harmonic may be obtained by cascading two such circuits. Both primaries may effect some phase displacement (e.g. n degrees and (30-n) degrees). Four phases may be obtained.
