Abstract: 505,171. Hinges. HONEY, F. S., and PYNE, D. W. Sept. 29, 1937, No. 26421. [Class 65 (ii)] [Also in Group X] A hinged window, door, or the like 1 is so constructed that it is capable of being slidably drawn into close sealing contact with a surrounding frame 3 so as to provide a closure that serves to prevent the passage of gas or the like between the hinged member and the frame. The window sash 1 shown in Fig. 1, is provided with an inclined edge 2, which, in the closed position of the sash, bears against the inclined surface 4 of the frame 3. Each hinge comprises a member 7 secured to the sash, a pin 7a, and a member 8 which is formed as a right-angled extension of a flat-bar 9 slidably mounted in a guide constituted by a tray 11 secured to the frame 3. The bar 9, at the end adjacent the hinge pin 7a, passes through a slot 14 in the end wall of the tray, and at the other end a screw-threaded extension 10 on the bar passes through a hole 15 in the adjacent end wall of the tray. The bar 9 is of such a width as to fit closely in the tray. When the sash is to be used normally, the hinge pin 7a is in its outermost position, and the bar 9 is then retained with the hinge pin in this position by means of a wing-nut 16 on the extension 10 and a removable locating- piece 17 which.is clamped between the end of the bar 9 and the adjacent end wall of the tray. When the sash is to be pressed on to the frame, the piece 17 is removed and the wing- nut 16 tightened to draw the bar 9, hinge, and sash inwardly.

Title: Improvements in or relating to process and apparatus for the precipitation of substances from solution, using solid precipitants
IPC: C22B3/02
Filed: 1968-06-04
Abstract: 1,216,596. Precipitating metals from solutions. KENNECOTT COPPER CORP. June 4, 1968 [June 14, 1967], No.26615/68. Heading C7D. A process for the precipitation of substances from solution using solid precipitants comprises maintaining a body of the solution in a reaction zone in contact with a mass of solid precipitant and introducing additional solution into the reaction zone under pressure from jet nozzles directed in the same sense circularly of the reaction zone. The apparatus essentially consists of an inverted conical reaction vessel 10, charged with solid precipitant, to which solution is provided under pressure by a manifold having branches 18a, b, c communicating with the lower inlet pipe, 20, for fresh solution. The solution is discharged through jets 23, in the manifold which all point in the same direction and act circularly with respect to the reaction zone. A second manifold with branches 19, a, b, c, is provided, fed from inlet pipe 21, and having jets acting in the opposite direction to the first. Means may be provided for alternating flow between two such manifolds. The swirling fluid overflows the top of the reaction vessel carrying the precipitated metal. The latter passes through screen 15 and collects on a sloping floor 16 of the outer container 11, from which it is periodically removed through pipe 17, the exhausted solution escaping via peripheral overflow launder 13, at the upper end of container 11, and through pipe 14.

Abstract: 637,232. Fluid-pressure servomotor-control systems. BUSSEI. E. Sept. 5, 1946, Nos. 26744 and 26745. Convention dates, March 24, 1942, and April 14, 1942. [Class 135]. [Also in Group XXXIII] A hydroplane vessel having automatic means for maintaining the hull at a predetermined height above the water such that the hydrovanes are always completely immersed, and automatic means for controlling rolling and pitching, comprises a hull 1 and a keel-like member 2 carrying screw propellers s and hydrovanes 3, 4 separately rotatable about an axis 5 and hydrovanes 6 rotatable about an axis 7. The degree of pitching and rolling is measured by a pendulum 9 and the velocities by gyrostats 12, 14. The sum of these two measures for rolling is applied to a servomotor 17 which corrects the hydrovanes 3, 4 through differential gearing 18, 18<SP>1</SP> and similarly the servomotor 16 corrects the hydrovanes 6 for pitching. Height is set by a float 19 which is adjustable by a hand wheel 27 and thereafter measures variations of height. Velocity of the variations of height is measured by gyrostats 22 and the sum of these measures is applied to a servomotor 28 which adjusts the hydrovanes 3, 4 to maintain constant height.

Title: Vehicle levelling systems
Inventor: WENHAM GRAHAM JOHN
IPC: B60G17/033
Filed: 1968-06-05
Abstract: 1,260,844. Vehicle suspensions; levelling. GIRLING Ltd. 5 June, 1969 [5 June, 1968], No. 26786/68. Heading B7D. In a vehicle suspension system the volume of fluid in suspension devices 8 associated with road wheels 6 at one end of the vehicle are controlled by a levelling valve 13 responsive to variations in the height of the sprung mass 4 of the vehicle adjacent the wheels 6 from a predetermined height, and this height is itself adjustable in accordance with variations of the height of the sprung mass 4 above the road wheels 5 at the other end of the vehicle. As shown, the valve 13 is pivotally mounted at 18 to the sprung mass 4, and is connected to the rear axle 3 by an operating arm 16 and link 17. When an increased load on the rear end tends to lower the valve 13 the operating arm 16 is rotated anti-clockwise to increase the supply of pressure fluid to the devices 8 and restore the position of the valve. The reverse happens when the load is decreased. An anti-roll bar 19 at the front end is connected to the valve 13 by links 24, 25a, 25b so that when the front end of the sprung mass is depresesdthe valve 13 is turned anticlockwise about its pivot 18 to cause a decrease in pressure to devices 8 and effectively lower the predetermined height to prevent changes in the attitude of the sprung mass. To prevent the angular position of valve 13 being changed by riding vibrations of the front suspension, a damper 27 is connected to the valve 13 and a lost motion device 28 of the form shown in Fig. 2 may be used to connect the link portions 25a and 25b. A similar device may be incorporated in the linkage 16, 17.

Title: Preparation of vinyl esters of chemically stabilized rosins and polymers thereof
Filed: 1950-11-03
Abstract: Vinyl esters of rosin which has been hydrogenated, dehydrogenated or disproportionated are prepared by heating the treated rosin with a molar excess of a vinyl ester of a low molecular weight saturated fatty acid in the presence of a cadmium, zinc or mercury salt of a strong acid (e.g. sulphuric, phosphoric, silicotungstic, trichloracetic, hydrochloric, or boron trifluoridecarboxylic acid), and separating the vinyl ester of the treated rosin, preferably by distillation.  The catalyst (which may have been formed in situ from a strong acid and a salt of a weak one) is inactivated, e.g. by addition of alkali.  The product may be washed with acid, alkali and water.  The term rosin includes wood rosin, gum rosin, acid fractions therefrom and tall oil.  The vinyl ester starting material may be the acetate, propionate, butyrate or hexoate.  Distillation of the vinyl ester of the stabilized rosin may leave a residue of polymerized ester. The vinyl esters of stabilized rosin may be polymerized in presence of a peroxide catalyst, by heating or by ultra-violet radiation.  Activators such as diacetyl or acetone may be employed. The polymers are soluble in hydrocarbons or chlorinated hydrocarbons. Peroxide catalysts mentioned are benzoyl; acetyl; dibenzaldi-; cumene hydro-; di(2,2-dimethyl benzyl)-; or di-tert.-butyl.  Tert.-butyl perbenzoate is also mentioned. Polymerization may be in bulk, in solution in an inert solvent or in an aqueous emulsion.  The polymers may be obtained as amorphous powders by precipitation with ethyl alcohol from the reaction mass.  They may be cooked with drying oils, e.g. tung oil, to yield varnishes and enamels, dissolved in solvents to yield ink vehicles, used as paraffin wax modifiers for moisture-proofing cardboard, or combined with natural and synthetic rubbers such as neoprene or GR-S to make solvent-type adhesives.
