Patent GB-814862-A (GB)
Title: Process of treating amalgams of metals which are difficultly soluble in mercury
IPC: C22C3/00
Filed: 1957-07-26
Abstract: An amalgam containing less than 10 per cent by weight of a metal difficulty soluble in mercury is heated to a temperature above 360 DEG C. at a pressure equal to or higher than the vapour pressure of mercury at that temperature to condition the amalgam for separation of mercury therefrom in the liquid phase. Separation of further mercury from the residual amalgam can be effected by oxidizing the metal in the residual amalgam to form an oxide covered amalgam powder and mercury substantially free from the difficulty soluble metal. Oxidation can be facilitated by adding to the amalgam, at any time before separation of mercury, a metal having a higher affinity for oxygen than the said difficulty soluble metal.  The added metal may e.g. be aluminium added in amount of 10-4 to 10-2 per cent by weight of the mercury in the amalgam, or manganese added in amount of 10-3 to 10-1 per cent by weight of the mercury.  The difficulty soluble metal may be obtained from the final enriched amalgam by distillation of the mercury.  The difficulty soluble metal may be iron, nickel, copper or manganese.

To present the rib of fat to the knife the core is flattened at 6 and has a leaf spring 40 at its rear to pull the gut tight over the front flattened part. Smooth arcuate guides 42 press the gut back from its rib of fat to make it prominent so that the knife cuts off the rib only. The knife is reciprocated by an eccentric 35 driven at a high speed through gearing from the main shaft 10 driven through worm gear from an electric motor 15. The knife 16 reciprocates between a plate 18 and an overlap guide 123 with adjustment by a handwheel 33 to position it close enough to the gut. Its inclination is adjusted by bolts 22 in slots 21. One flange of the pulley 4 is detachable to allow the gut and its core to be placed in position. The knife 16 is quickly detachable by having slots for the bolts attaching it to the plunger 25 of its eccentric 35. A handwheel 43 is used to turn the shaft 10 to facilitate removal and attachment of the knife 16 &c.

Wall plates of ceramic material, or glass, are secured to smooth surfaced walls by means of a flexible web made, e.g. of synthetic material, or paper, woven fabric or a fleece of glass fibres, and coated on both sides with a layer of adhesive wall plate cement, the plates being fixed to the wall by pressing a sheet of the web on to the back of each plate and pressing the latter firmly against the wall with a suitable tool. The web may be supplied in roll form in which case a strip of the web, preferably equal to the width of a tile, is pressed, e.g. with a squeegee or a roller consisting of a number of parallel wheels, on to the wall, the tiles then being applied to the strip. The adhesive can be made on a basis of linseed oil, or bitumen cement, but is preferably made of an adhesive which remains permanently plastic, e.g. one prepared on the basis of paraffinic hydrocarbons with fillers and possibly synthetic compounds. Suitable hydrocarbons are proto-paraffins which are colloidal mixtures of paraffinic hydrocarbons of various chain lengths which incorporate at least 1 per cent, and preferably more than 5, and up to 25 per cent of oil.

Filed: 1930-08-15
Abstract: 360,975. Aircraft launching apparatus. RICHARDS, A., Engineers' Department, Admiralty, London. Aug. 15, 1930, No. 24477. [Class 4.] In an aircraft-launching apparatus of the type in which the aircraft is mounted on a trolley which is accelerated along a slider which is itself accelerated along a fixed trackway, the slider is connected directly to the moving element of the prime mover and carries a receiving vessel forming part of a fluid retardation system, in which towards the end of the launching stroke, fluid is forced through a passage or passages of gradually diminishing area into the receiving vessel. A frame structure 1, Fig. 1, mounted on a pedestal bearing 2 is fitted with hand or power training gear 5, 6, 7 and may be locked in any position. The structure 1 carries a slider 8 which mav slide on machined faces or on rollers 9 mounted on adjustable eccentric pins. Slider 8 is connected by a crosshead to a part 10 of a ram 11 operated by a fluid under pressure. As shown, gases from a combustion unit 12, spring mounted on the supporting structure 1, are led to a cylinder 14 mounted in the trackway 1, and containing the ram 11. Rope multiplying gears 15, 15a, giving a 3 : 1 ratio, connect the slider 8 to a trolley 16 on which the aircraft is mounted. The ram 11, Fig. 2, is hollow and has a number of holes 17 near its piston 18 and one or more inclined keys 19 between the holes and the piston. The cylinder has an internal flange 20 having slots 21 to receive the keys 19 at the end of the launching stroke. The ram is connected by a pipe 22 to a tank 23 carried by the slider: Before launching the hollow ram, its clearance space in the cylinder, the pipe 22, and part of tank 23 are filled with liquid. During the launching stroke the liquid displaced flows through the holes 17 and on into tank 23 but as soon as the inclined keys 19 engage the slots 21 in the flange 20 the liquid passing through the slots is throttled to an increasing degree finally bringing the ram to rest. Perforated baffle plates are fitted in the tank 23. A rack andpinion gear is fitted for moving the slider and trolley into position and is operated by a handle 24 through gears in a box 25. Alternatively rope and drum, or chain and sprocket gear may be used. A releasing device for the slider may be operated by hydraulic pressure acting on a piston in a dashpot connected to the device which dashpot may be employed to absorb the energy of recoil on launching. According to a modification the single ram 11 may be replaced by a nest of rams, of which the smallest is connected to the slider.

Abstract: 223,389. Vickers, Ltd., and Nasmith, J. I. Oct. 4, 1923. Guards.-In guards for machines wherein reciprocating tools operate on material fed over a horizontal bed, of the kind in which a guard member free to slide vertically into the safety position is raised by the introduction of the work, a rigid pivoted lever engaged by the leading edge of the material lifts the guard. In a. corner-mitering machine for box-making, the guard F, G, enclosing the tool on three sides, normally descends by gravity close enough to the table A to prevent access of the operator's fingers, but can be raised by a roller M on a bell-crank lever K turning on a pivot J in the shield extension E of a fixed bracket C, between which and the machine frame B is formed a guideway for an extension H of the guard. The work is adapted to contact with a roller N on the other arm of the lever K to raise the guard sufficiently for its introduction. An adjustable spring R acts in compression or, as shown, in tension to counterbalance part of the weight of the guard. In a modification, the bellcrank lever is replaced by a pivoted arm having a curved downward projection for engagement with the work.
