Title: Lubricant delivery control
Inventor: LINE GERALD D
IPC: F01L1/245
Filed: 1960-07-18
Abstract: 884,721. Lubrication. EATON MANUFACTURING CO. July 18, 1960, No. 25055/60. Class 12 (3). In a lubricant supply means for engine valve linkage, a push-rod 18 has a passage therethrough which receives oil pumped via a combined non-return and metering ball valve, via a chamber 16 of a slidable thrust-transmitting member 14, and via ports 25, 24, 26 in the member 14, in a tappet body 13 surrounding the member 14, and in a block 12 respectively; the clearance 22 between a ball 23 and a passage 19 of the valve meters the oil supply. The ports are aligned when the member 14 is raised by a cam (not shown) which urges against a face 28 of the body 13. The members 13, 14 are urged away from axial engagement by a spring 29 and end play is further eliminated by oil from the chamber 16 which passes through a check-valve 30 into a chamber 31 containing the spring 29. The ball may be retained by projections 35 or by a spring. Specification 751,705 is referred to.

Abstract: 1,061,163. Measuring dimensions photoelectrically. DAVY & UNITED ENGINEERING CO. Ltd. July 20, 1965 [June 22, 1964], No.25719/64. Heading G1A. Apparatus for measuring the separation of the rolls of a rolling mill comprises a light source at one side of the rolls and light detecting means at the other side to detect an edge of each of the rolls. In one form two spaced parallel beams are produced from a single source and projected through the gap so that each is partially masked by one of the rolls. The beams are then transposed by reflectors so that the masked boundaries are adjacent. Their separation, giving a measure of the roll spacing, is determined by a rotating optical system which sweeps them in sequence over a photo-cell with an associated counting system. In an alternative embodiment a single collimated beam is projected between the rolls, to be partly masked thereby, and past a central stop, thus producing two beams which are transposed as already described.

Abstract: 736,839. Making cartridge cases. REMING- TON ARMS CO., Inc. Sept. 25, 1953, No. 26517/53. Classes 83(2) and 83 (4). Extruding; pipe-end closing.-A cartridge case, preferably of aluminium, is made by producing by extrusion a thin-walled tube 23, Fig. 2, having an external enlargement 30 at one end, radially contracting the thickened end of the tube so as to transfer the enlargement 30 to the inside of the tube thereby forming a constriction 43, Fig. 7, and heading the tube at the thickened end. An aluminium slug 22 is inserted in a closed-ended die 15, Fig. 1, having a tapered side wall 18 and a counterbore 20, and is extruded rearwardly by a punch 25 to form the tube 23. The billet has a conical recess 24 which co-operates with the conical end 25<SP>1</SP> of the punch for centring the billet and also holds lubricant. The punch has a cylindrical land 26 and a tapering skirt portion 27. The extruded tube 23, Fig. 2, has a cylindrical bore and a slightly tapered external surface. After extrusion the conical end 34 of the tube is cut off by a rapidly rotating saw. The tube is then forced axially through a die 36, Fig. 7, having a tapered bore 37 and a bell mouth 37<SP>1</SP>. This operation is performed in three stages using three punches, such as 42, of different diameters so as to partially close the end of the tube at 43. The tube is then supported in a heading die and a punch is moved into the open end of the tube to engage the constriction. A heading tool then acts on the thickened end of the tube to form the head with the primer pocket 47, flash hole 48 and extraction rim 49, Fig. 10. During the heading operation the circumferential wall at the head part is tapered to correspond with the tapering outer surface, produced during extrusion, of the remainder of the case.

Title: Synthesis of organic oxygen-containing compounds
IPC: C07C27/22
Filed: 1954-09-15
Abstract: Organic oxygen-containing compounds, particularly aldehydes, are obtained by a process comprising reacting, at a temperature of from 130 DEG  to 250 DEG  C., and at a pressure of from 2000 to 9000 lbs. per sq. inch, one or more compounds containing olefinic unsaturation simultaneously with carbon monoxide and hydrogen in the presence of a catalyst comprising cobalt oxide.  The catalyst is preferably obtained by the thermal decomposition of cobalt carbonate.  Suitable olefinic compounds for use as starting materials are, for example, ethylene, propylene, butylene, pentenes, hexenes, heptenes, diisobutylene, tripropylene, triisobutylene, methyl acrylate, ethyl crotonate, allylidene diacetate as well as olefinic hydrocarbon feeds from oil and gas cracking operations.  The cobalt oxide catalyst is preferably used in suspension in the olefinic feed stock or in mineral oil, toluene, butanol or the crude converter product which may be recycled.  In the examples: (a) propylene yields butyraldehyde with some butanol; (b) tri-isobutylene yields a mixture of aldehydes and alcohols containing thirteen carbon atoms; (c) ethyl crotonate yields a mixture of deltavalerolactone, ethyl 5-hydroxyvalerate, ethyl 2-formylbutyrate and ethyl 4-formylbutyrate; (d) allylidene diacetate yields 4,4-diacetoxy-butyraldehyde; and (e) a mixture of monoolefines containing 4 carbon atoms yields a mixture of pentanals and pentanols when treated with carbon monoxide and hydrogen in the presence of a cobalt oxide catalyst.
