IPC: C14C3/04
Filed: 1964-11-18
Abstract: In tanning pelts and skins and re-tanning leathers, wet acidic pelts, skins or leathers, having a pH not exceeding 4, are drummed with powdered zirconium sulphates having a basicity between 0 and 50%, then rinsed with water without basification, and then de-acidified, in the presence of water, with a carbonate and/or bicarbonate and a formate or acetate of ammonia and/or an alkali metal and/ or an alkaline earth metal, until an equilibrium pH between 4 and 6 is attained in the resulting liquor and leather. Zirconium sulphates containing finely dispersed silicic acid may be used.  Ammonium or sodium bicarbonate and sodium acetate or formate, or calcium formate, are specified for de-acidification, which may be carried out with the concurrent use of known tanning or re-tanning agents.

The flame resistance of the plastics may be increased by adding phosphate and halogen-containing plasticizers such as chlorinated paraffins or chlorinated polyphenol resins. A surrounding screen 12 of woven wire is preferably aluminium mesh. The screen 12 is wrapped around the tube and secured by crimping 14 or by rivets &c. The screen 12 is wrapped loosely around the tube 10.

In a power braking device 10, e.g. for use in a power brake system having provision for manual operation as in Specification 1,034,137, the outlet seat 54 from chamber 32 to a pressure chamber 18, provided with a two-way check valve 24, is closed by a ball 50 carried by a valve stem 38 which is loaded by a spring 64 which also abuts an elastomeric rubber or synthetic rubber ring 58 retained within a valve stem groove 56 and acting as a diaphragm seal to permit limited displacement of the stem 38 when the ball 50 is unseated at 54 by seating contact with a hollow stem 14 which is normally unseated from the ball 50 and providing communication, via the hollow interior thereof, between chamber 18 and reservoir 20. The valve assembly is normally balanced with respect to inlet pressure in chamber 32 by making the diameter of the stem 38 equal to that of the contact area of seat 54. In an alternative embodiment (Fig. 2, not shown), overstressing of the diaphragm (58) is prevented by a C-washer (68) mounted in a groove on the chamber (18) side of the stem (38) and movable only between fixed abutments to limit the displacement of the stem (38), the effective diameter whereof is made equal to that within chamber 32 by means of a sleeve (75), to maintain pressure balance. A passage 40 through the stem 38 vents leakage behind the ball to chamber 18 to prevent pressure expulsion thereof.

Abstract: 1503994 Pile-drivers VAN KOOTEN BV 5 Dec 1975 [10 Dec 1974] 49934/75 Heading B3H A Diesel pile-driver comprises a combustion cylinder 3, a striker 2 extending into the combustion cylinder, a piston 1 located in the combustion cylinder and a fuel injector 6 for supplying fuel between impact surfaces 5, 4, of the piston and striker, which define together an annular main combustion chamber 32 and an annular pre-combustion chamber 10, the chambers 32, 10 communicating with each other via an annular passage 34 of relatively short axial length. Fuel is sprayed by a nozzle 30 on to three zones (13), Fig. 4 (not shown), on the surface 4 of the striker, and it is atomized and scattered like a curtain 12 when the piston impacts the striker. Combustion takes place in the chamber 10 and is followed by combustion in the main chamber 32, the restriction formed by the passage 34 causing a slight delay in the initiation of combustion in the main chamber. The precombustion chamber may alternatively be formed in the piston, rather than the striker, Figs. 6, 9 (not shown), The provision of the two combustion chambers ensures full combustion of the fuel charge and hence full stroke of the piston when driving piles into soft ground.
