Title: Improvements in anti-corrosion mineral oil compositions
IPC: A61B5/02
Filed: 1944-09-21
Abstract: A mineral oil composition, suitable for use under conditions in which it is liable to pick up or absorb small amounts of water from atmospheric condensation or from other sources of contamination, contains a minor quantity of an anticorrosion agent which promotes the formation of an oil-in-water emulsion when the oil is in the presence of water and also a minor quantity of an anticorrosion agent which promotes the formation of a water-in-oil emulsion when the oil is in the presence of water, the two anticorrosion agents being chosen from the lists given below and being added in such quantities that their emulsifying tendencies are mutually offset so that the oil composition exhibits substantially no emulsifying tendency in the presence of water. The anticorrosion agents which promote the formation of an oil-in-water emulsion are the alkali mahogany sulphonates, alkali naphthenates, alkali salts of resinified reaction products of alkylated phenols with aldehydes and amines or ammonia, and ethanolamine soaps.  The anticorrosion agents which promote the formation of a water-in-oil emulsion are the naphthenates of polyvalent metals such as calcium, zinc, lead, copper aluminium or beryllium, the polyvalent metal mahogany sulphonates and oleates, polyvalent metal salts of alkylated sulphuric acid, polyvalent metal salts of resinous reaction products of alkylated phenols with aldehydes and ammonia, calcium phenyl stearate and laurylamine salts. The mineral oil compositions may contain other ingredients in addition to the anti-corrosion agents, for example, sludge dispersers, thickeners, viscosity index improvers, oiliness agents, antioxidants and dyes.  Mineral oil compositions specified are turbine oils, lubricants for the bearings of machinery which is much in contact with water such as paper mill and refrigerating equipment, crankcase lubricants, steam engine lubricants, hydraulic fluids, textile oils, cutting oils and insulating oils.  In examples, mineral oil compositions are described which contain sodium mahogany sulphonate and zinc naphthenate.  The results of tests are given in which such compositions are compared with mineral oil solutions of sodium mahogany sulphonate and with mineral oil solutions of zinc naphthenate.

Title: Fluid pressure operated jacks
Inventor: HANCOCK KENNETH GEORGE
IPC: B64C25/22
Filed: 1955-06-24
Abstract: 807,856. Pneumatic jacks. ELECTRO-HYDRAULICS Ltd. June 22, 1956 [June 24, 1955], No. 18369/55. Class 8(2). [Also in Group XXIX] The velocity on extension or closure of a fluid actuated jack, which may operate an aircraft undercarriage, is reduced over the last part of its travel by means of a damping valve and by arranging for the inlet valve to the jack to be controlled by the pressure in a damping chamber. The jack comprises a cylinder 1, a main piston 6 having an extension 7 connected to a main piston rod 8 and end fittings 2 and 9. A floating piston 46 is mounted on the rod 8. Fluid pressure is supplied through a port 34 in a pressure operated valve 33 and passes via a port 40, an aperture 41, a passage 42, a restrictor 43 and an outlet 35 in a connection 3, through a passage in a gland housing 10, and acts on the piston 6. When the piston moves outwardly the exhausted fluid passes through a connection 4 and a port 20 to a tank via a connection 22. When the piston nears the end of its stroke, the floating piston seals the outlet to the connection 4 and the fluid remaining in the cylinder passes through a connection 5 to a damping valve. This fluid enters the valve through a port 21 passes through passages 26 moves a spring-loaded valve 28 and flows through the port 20 and the connection 22. The terminal velocity of the jack is controlled by expelling oil from the jack through a labyrinth restrictor 31. Increase in pressure in the damping chamber is transmitted via a flexible pipe 24 to a surface 44 in the piston 36 of the inlet valve 33. When the pressure in the pipe 24 exceeds the inlet pressure, the piston 36 is moved to restrict the inlet flow. To retract the jack, fluid is supplied to the connections 4 and 5 through the connection 22 and the port 20, and fluid on the other side of the piston passes through the connection 3 into the valve 33 and through the port 35. This fluid passing through the restrictor 43 causes a pressure drop and a sleeve 37 is moved and partially or completely closes the port 40 and thereby damps the return movement of the piston. By providing spring loading for the piston of the pressure operated valve the inlet can be obstructed at a constant pressure difference between pressure in the damping chamber and of the supply. Alternatively, by having unequal areas on the piston, the supply to the jack could be obstructed when the supply pressure is some ratio of the pressure in the damping chamber.

Title: An improved method of preventing the formation of ice on an overhead power transmission line
Inventor: SNELLING ERIC CHARLES
IPC: H02G7/16
Filed: 1967-04-24
Abstract: 1,141,390. Current transformers. MULLARD Ltd. 24 April, 1967, No. 18670/67. Heading H1T. [Also in Division H2] The formation of ice on an overhead power transmission line is prevented by an automatically operating heating circuit comprising at least one conductor extending along the line, the heating current being derived from a secondary winding of a transformer of which the primary winding is the line itself. As shown in Fig. 1, a tubular ferrite core E, having a Curie point in the range 2‹ C. to 15‹ C. is mounted on the power line A, with one end of the secondary winding attached at B to the line A, and the other end attached to a heating conductor H, helically wrapped around the line A and connected to it at a remote point. The heating circuit is automatically brought into operation when the ambient temperature falls below the Curie point of the core. The secondary circuit may heat the core or a second core heating circuit may be provided in series or parallel with the secondary winding. The core material may be a tertiary or quaternary alloy, and the transformer may have cooling fins and be protected against moisture and corona discharge. In another form (Fig. 2, not shown) a silicon-iron cored transformer is used and a temperature sensitive switch (V) short circuits the heater at ambient temperature above about 7‹ C. A fall in temperature to the freezing point causes the switch to open and current to flow in the secondary circuit. Transformers of either type are mounted adjacent a tower support (Figs. 3, 4 not shown) or supported directly by the tower (Fig. 5, not shown). In a further embodiment (Fig. 6, not shown), a jumper conductor (S) between two power lines (A) supported by insulators (C) at a tension tower is threaded several times through the core to increase the number of primary turns of the transformer which is suspended from the tower by supports (T).

Abstract: 484,865. Steam turbine plant. AKT.- GES. BROWN, BOVERI, & CIE. July 7, 1937, No. 18858. Convention date, July 7, 1936. [Class 110 (iii)] [Also in Group XII] In a power plant consisting of a main turbine supplied from a pressure-fired steam generator, and an air blower driven by an exhaust gas turbine operated by the waste gases of the generator, the exhaust gas turbine is assisted by an auxiliary steam turbine supplied with working fluid tapped from the main machine. The steam generator a is supplied with air under pressure by the blower c which is driven by the exhaust gas turbine b, and an auxiliary steam turbine e supplied with steam tapped from the main turbine d. An increase in load on the main turbine d causes an increase in the tapping pressure which in turn causes an increased quantity of steam to flow through turbine e thus increasing the output of blower c to suit the new conditions. The exhaust from the turbine e may be used in a feed-water heater g or returned to the main turbine at h or both these arrangements may be used together so that with a high load on turbine e steam is returned to, and with a low load it is extracted from, the main turbine. In an alternative arrangement, a distiller may be used as a condenser for a portion of the steam used in the auxiliary turbine e, the steam produced by the distiller being condensed in a feed-water heater. The Specification as open to inspection under Sect. 91 comprises also a plant in which the whole of the exhaust steam of the turbine is used in a distiller. This subject-matter does not appear in the Specification as accepted.
