Patent GB-2479704-A (GB)
Title: Hydrant valve
Inventor: CLARK PAUL
IPC: A62C35/20
Filed: 2009-12-23
Abstract: In a hydrant the operation of the valve 5 is based on lifting the valve plug 5 vertically from the seat 6 then tilting the plug 5 away from the inlet to provide an uninterrupted bore 9. A stem 4a is threaded with a mating stem nut 4b shaped to include provision for a slider mechanism 8 and a receiver 11 for a plug axle. The plug axle has an axis A-A' which is offset so as not to bisect with the axis of the stem 4a. The stem nut 4b is of sufficient length so as to minimize the bending loads on the thread when the plug 5 is loaded during closure of the valve. During operation of the hydrant the stem 4a is rotated by means of an external handle (4, Fig. 1) at its upper end and consequently the stem nut 4b and plug 5 rise vertically for a certain distance. Further rising of the nut 4b and plug 5 cause the slider mechanism 8 to rotate the nut 4b and plug 5 off the center of the bore 9 and simultaneously, as the plug 5 contacts the walls 7 of the hydrant, rotates the plug 5 around its axle 12 so as to leave the plug 5 in a plane orthogonal to the plane in which it originally sat on the seat 6. During closure of the valve the actions occur in reverse.

Title: Improvements in flux washes
IPC: C23C2/30
Filed: 1934-04-07
Abstract: Froth-stabilizing agents which reduce the surface tension and increase the viscosity of the solutions are added to flux washes comprising dilute aqueous solutions of fluxing compounds such as hydrochloric acid, zinc chloride, salammoniac, or zinc ammonium chloride.  Froth stabilizers referred to are glycerine, tallow, oatmeal, bran, glucosides such as soapbark, licorice root, saponin, amygdalin, phloridzin, populin, salicin, soap wort root, or tannin, and carbohydrates such as xylose, dextrose, cane sugar, galactose, lactose, maltose, corn starch, or potato starch.ALSO:The surface of a metal to be galvanized is prepared by passing the metal through a flux wash comprising a dilute aqueous solution of a fluxing compound such as hydrochloric acid, zinc chloride, salammoniac, or zinc ammonium chloride, and a froth stabilizer which reduces the surface tension and increases the viscosity of the solution.  The froth stabilizer may be glycerine, tallow, oatmeal, bran, a glucoside such as soapbark, licorice root, saponin, amygdalin, phloridzin, populin, salicin, soap wort root, or tannin, or a carbohydrate such as xylose, dextrose, cane sugar, galactose, lactose, maltose, corn starch, or potato starch.  When a salt such as zinc chloride &c. is used in the flux wash the solution carried into the molten zinc bath by the metal causes the formation of a frothy flux blanket on the surface of the molten zinc.  The flux blanket is continually renewed by the entering metal and spreads gradually over the surface of the zinc, spent flux being removed at a point remote from the point of entry of the metal.

April 3, 1930, No. 10600. Convention date, Sept. 10, 1929. [Class 100 (i).] To enable the speed of sheet-fed rotary printing- machines to be increased while allowing sufficient time in which to register the sheets by hand against the front lays 12, the sheets 8 after being taken by the grippers 7 of a feed cylinder 1, or by grippers on an impression cylinder arranged near the lays 12, are moved outwards from the axis of the cylinder by means of rollers 3 on levers 4 which are actuated by a cam 6. The levers 4 may be carried by the cylinder 1, or they may be mounted on stationary axes. The motion of the rollers 3 causes the sheets to be drawn away from the laying-on table 11 at a greater speed than the peripheral speed of the impression cylinder 2, and, as the sheet clears the lays 12 quickly, more time is allowed for registration. The rollers 3 may be replaced by air nozzles which may be stationary or movable, and the sheets are moved away from the cylinder by blasts of compressed air. Preliminary oscillating or rotating grippers may feed the sheet from the lays 12 to the cylinder 1. Guides 12 limit the outward motion of the sheets. A transferring cylinder may be arranged between the cylinder 1 and the impression cylinder 2.
