Abstract: 483,317. Pressure-regulating valves ; fluid - pressure servomotor - control systems. MEADOWCROFT & SON, Ltd., W., and MEADOWCROFT, W. Oct. 16, 1936, No. 28099. [Class 135] In a machine for carbonating beer, aerated waters and the like, wherein the supply of carbonic acid gas to the storage chamber D is controlled by a pressure-reducing valve A, a spring-loaded piston j<2> arranged in the chamber D, communicating with the outlet side E of the valve A, acts positively through a lever H to move the valve suddenly into fully-open position upon a drop in storage pressure, while, upon a rise in such pressure, the piston moves suddenly in the reverse direction so as to allow the pressure on the inlet side B of the valve to close the-latter. The sudden action which occurs when the static friction between the piston j<2> and its cylinder is overcome, prevents freezing of the gas. The lever H may have a cam surface coacting with a roller carried by a plunger F arranged above the valve A. As shown, however, the lever H carries tappets O<1> and P controlling spring- closed valves o<1> and p<1>, the valve o<1> controlling communication, through ports O, o<4>, between the atmosphere and the upper cylinder space l<1> of a servomotor, the plunger L of-which is arranged above the plunger F, while the valve p<1> controls communication, through a port P and a conduit Q, between the space l<1> and the inlet side B of the valve A. As the piston j<2> moves down, due to a drop in outlet pressure, the valve p<1> is opened and the valve o<1> closes. Inlet pressure entering the space l<1> thus forces down the plunger L and opens the valve A. As the piston j<2> moves up, due to a rise in outlet pressure, the valve o<1> is opened and the valve p closes. The space l<1> is thus vented, allowing the inlet pressure to close the valve A and to lift the plungers F and L. According to the Provisional Specification, spring-controlled toggle levers may be provided to produce the sudden action, and the arrangement may be such that the valve is allowed to open on reduction of storage pressure and is closed by the lever on increase of pressure.

Title: Improvements in or relating to resistance wire and methods of making the same
IPC: H01B1/02
Filed: 1930-09-22
Abstract: A resistance wire is made by coating a molybdenum wire with a surface layer of beryllium and oxidizing the surface to form a coating of beryllium oxide.  Beryllium metal is finely powdered and held in suspension in an amyl acetate solution of nitrocellulose.  This coating material is then applied to a molybdenum wire and heated slowly until it dries.  Alternatively the beryllium may be applied to the molybdenum base by means of a spray of molten metal in an atmosphere of hydrogen or other reducing gas.  The coated wire is then heated to a temperature above the melting-point of beryllium, i.e. to about 1300 DEG  C. in an atmosphere of hydrogen, the molten beryllium combining with molybdenum to form a mixture of molybdenum and beryllium with a layer of beryllium at the surface.  The wire is then cooled in an atmosphere of hydrogen, and may be wound into any shape, for example for a toaster or heater for use in an oxidizing atmosphere, or in vacuum tubes, electric lamps, &c.  When heated in an oxidizing atmosphere a layer of beryllium oxide is formed which prevents deterioration of the resistance wire and is sufficiently insulating to enable auxiliary insulating supports to be dispensed with, so that the wire may be applied directly to the surface to be heated.  The Specification as open to inspection under Sect. 91 (3) (a) states also that tungsten, tantalum, or other refractory substances may be employed instead of molybdenum, and other oxides such as those of aluminium or magnesium may be employed instead of beryllium oxide.  When magnesium is employed, an atmosphere of helium is employed instead of hydrogen.  This subject-matter does not appear in the Specification as accepted.
