Title: Improvements in or relating to apparatus for rolling tapered metal discs
IPC: B21H1/02
Filed: 1925-05-27
Abstract: 257,037. White, A. E., (Budd Wheel Co.), May 27, 1925. Rolling discs. - A mill for rolling tapered discs comprises two conical rolls mounted with their lines of contact with the work converging towards the larger end of the rolls, the taper of the rolls being so proportioned with respect to the diameter of the disc that the rolls are in rolling contact without substantial slip throughout the rolling. The blank D fed along a guide-way 106, Fig. 2, to a spring stop 107 is placed by hand on one of the four mandrels 66 of the feed wheel 65 and is clamped to rotate freely in position by an arm 72 pivoted at 73 which is closed over the end of the mandrel by a projection 102 engaging a cam track 104 as the feed wheel is rotated to bring the blank into working position between the rollers 5. The feed wheel 65 mounted on the shaft 58 is rotated a quarter of a revolution of a time to bring a fresh blank into position by a hand controlled motor 57 driving the feed wheel through worm and other gearing. Lateral movement of the work to the left during rolling is prevented by a track 90 taking any thrust of the mandrel 66 through a pin 91, while movement to the right is prevented bv a curved track section 92 supported on three adjustable spring-pressed plungers 93, against which a track roller 101 on the arm 76 bears. The plungers may have hydraulic or pneumatic resilient means. A circular cam 88 bearing through an intermediate pin against the block 85 permits the arm 72 to grip the blank only when in rolling position and at other times forces it away. A projection 89 bearing on the shaft 58 limits the outward rocking of the arm 72. The roll pass is initially adjusted by pivoting about the shaft 11 and tightening the bolts 16 in their slots 17. The conical rolls 5 are mounted on rotated shafts 6, one of which is moved towards the other during rolling by a pin 37 moved axially in a screwed sleeve when the squared end of the pin is rotated along with a worm wheel 39 driven through gearing by an electric motor 44. The upper end of each shaft 6 has a squared portion 24 and a conical portion 25 over which the roll 5 fits and is secured by a long bolt 27. The shaft 6 is provided with roller thrust bearings 9. Specification 257,483 is referred to.

Filed: 1941-11-05
Abstract: 578,993. Air-screws. MILNER, H. L. Nov. 5, 1941, No. 14282. Drawings to Specification. [Class 114] The blades of an air-screw are set individually at such pitch angles as will cause them to have equal thrust moments, irrespective of slight differences in form and dimensions so that the complete air-screw will be aerodynamically balanced, the angles being determined by measuring, by physical means, the differences in form or dimensions of each blade from those of a master blade and from these differences, computing the thrust moment produced thereby. The pitch setting of the master blade to produce such a moment is then calculated and such pitch settings applied as a correction in the setting up of the propeller blades. The differences in form of the blade may be obtained by determining the angular position of the line of zero-lift relatively to a datum plane, e.g. the flat face of the blade, at each of a number of positions along the blade and noting the difference between those angles and the corresponding angles of the master blade. These angles may be measured by the aid of the gauge described in Specification 578,994.

Title: Coated glass articles
IPC: C03C17/25
Filed: 1956-05-09
Abstract: A window closure comprises a curved sheet of glass having a metal oxide coating of varying thickness on a surface thereof, said coating effecting heat and light absorption, characterized by the fact that the metal oxide coating covers only a portion of the glass sheet, the remainder of the sheet being substantially clear, and that the thickness of the coating increases progressively outwards from the clear portion.  The sheet may be curved both longitudinally and transversely, so as to make a car windscreen with side wings and a roof portion, and the coating may be thickest in the roof portion. The window closure may be prepared by heating a flat sheet of glass, allowing it to sag into the shape of a mould, then spraying the heated glass with a solution of the chloride of tin, antimony, bismuth, iron, titanium or mixtures thereof in water, hydrochloric acid or methanol.  The variation in thickness of the coating may be achieved by the use of spray nozzles producing sprays of "tear-drop" or "dumb-bell" shape, and also by altering the angle of the spray with respect to the sheet, and the speed of passage of the sheet past the spray.  More than one coating may be applied, and the sheet may be reversed end for end between applications so as to avoid any variation in thickness between the leading edge and the trailing edge.
