Title: Improvements in or relating to the manufacture of cutlery
IPC: B24B3/36
Filed: 1946-11-04
Abstract: 618,396. Serrating cutlery blades; work-holders. FAIREST, Ltd., M., FAIREST, M., and AKERS, H. Nov. 4, 1946, No. 32616. [Classes 83 (ii), 83 (iii) and 83 (iv)] A machine for serrating knives comprises a series of spaced steel discs mounted for rapid rotation and means for bringing the rotating discs and the edge of a knife blade into contact. Two work-holders 37, mounted on a vertically adjustable bracket 13, each comprise a pair of standards 38, on a base-plate 39, carrying between them a square bar 43 which may be set with its faces at any desired angle, and from the front upper face 46 of which project screws spaced about 1¢ inches apart, on which are mounted cylindrical knife supports 48 with V-shaped notches under which the cutting edge of the knife to be serrated engages. The rear edge of the knife engages in a similar but larger support 55 carried by a screw 54 in a slide block 53 carried on parallel rods 51 projecting from the front face 52 of the square bar 43. The knife blade 69 is gripped between the supports 48, 55 by the initial depression of a pedal 62 acting through a bell-crank mechanism to cause the slide block 53 to be advanced along the rods 51 towards the square bar 43. Further depression of the pedal 62 is taken by the rod 67 against the spring 65 in the spring connector 63, thus limiting the amount of pressure to be applied in holding the blade. The pillar 12 extends beyond the bracket 13 and carries a sleeve 24 on a bearing 23. Secured to the upper end of the sleeve 24 is a mounting block 25 bored to receive a horizontal bearing and tool spindle 26, 27 and carrying a bracket 28 upon which the driving-motor 29 is mounted. The tool 32 comprises a number of steel discs, say, twentyfour, each 0.020 inch thick, clamped between end plates and spaced by thin washers, say, 0.026 inch thick. The discs are about 6 inches in diameter and are driven at about 6000 r.p.m. The whole tool-mounting may be swung about the bearing 23 by handles 36, and in operation forward swinging of the tool 32 causes it to cut through the cutting-edge of the blade 69, with diminishing depth of penetration due to the inclination of the blade in the holder, until the tool is carried clear of the blade, the forward swing being limited by the stop 72, 73. The angular approach of the tool discs, Fig. 7, produces tapered, saw-like teeth whose depth at the cutting edge may be adjusted by varying the height of the bracket 13, and whose length may be varied by varying the inclination of the blade in the holder by rocking the bar 43 or by adjusting the heights of the knife supports 48, 55. The sets of serrations are positioned by the use of gauge pointers 70, 71, Fig. 7. Burrs are removed in the final glazing or polishing.

Title: Improvements relating to the hydrocatalytic treatment of waxes
Inventor: REES HOWARD
IPC: C10G45/02
Filed: 1965-07-30
Abstract: In a process for the hydrocatalytic refining of waxes or lubricating oils at elevated pressure in the presence of hydrogen and a hydrogenation catalyst, in which the feedstock is changed from a microcrystalline to a crystalline wax or from a solvent-treated to a non-solvent-treated grade of lubricating oil, the changeover is effected by discontinuing the passage of the existing feedstock while continuing the passage of hydrogen, substituting an alternative petroleum hydrocarbon feedstock, raising the temperature to above that used for the first-mentioned feedstock up to a maximum of 750 DEG  F. for a period of from 5 to 50 hours and then lowering the temperature and commencing the processing of a crystalline wax or non-solvent-treated grade of lubricating oil.  The alternative feedstock may be the feedstock which is about to be processed or a "buffer" stock such as a gas oil.  Preferably, the alternative feedstock is processed at a lower pressure than the original or final feedstock.

Patent GB-1086974-A (GB)
Title: A method of producing unalloyed steels which exhibit improved machinability
IPC: C21C7/06
Filed: 1966-07-21
Abstract: The machinability of carbon steels is improved by carrying out a preliminary deoxidation with one or more metals having a high affinity for oxygen, such as aluminium, magnesium, zirconium or calcium, or alloys thereof, and then, after the deoxidation products have risen out of the bath, deoxidising finally with an alloy rich in silicon and substantially free from aluminium, whereby there are formed in the bath glassy occlusions rich in silica.  In a modification of the process the preliminary treatment may be partially or wholly replaced by a vacuum degassing treatment, while it is also possible to add to the melt nucleating elements such as tantalum, niobium, titanium or vanadium.
