Patent GB-743017-A (GB)
Title: Improved lubricating greases
IPC: C10M169/00
Filed: 1953-05-07
Abstract: The mono-formic ester of dihydroxystearic acid is prepared by reacting oleic acid with hydrogen peroxide in the presence of formic acid.  The ester may be hydrolysed, for example with alcoholic caustic potash or aqueous lithium hydroxide, and yields a complex formate-dihydroxystearate soap which may be employed as thickener in lubricating greases (see Group III). Dihydroxystearic acid, which is insoluble in ether, is obtained by acidifying the complex soap and extracting with ether.ALSO:A lubricating grease which maintains its structure when subjected to mechanical stress comprises a major proportion of lubricating oil thickened with a minor proportion of a complex soap obtained by neutralizing a mixture of dihydroxystearic acid and a C1-C5 monocarboxylic acid with a metal base. The lubricating oil may be mineral oil or a synthetic lubricating oil such as diester, a complex ester or a hydrocarbon polymer. Preferred lubricating oils are di-2-ethylhexyl sebacate and complex esters derived from dibasic acid, glycols and moonbasic asids.  The C1-C5 monocarboxylic acid may be formic, acetic, propionic, butyric, valeric, furoic or acrylic acid, while the metal base may be a hydroxide of aluminium or of an alkali or alkaline earth such as lithium, sodium, potassium, calcium or barium.  In addition to the complex soap, the grease may contain a simple soap of C10-C24 fatty acid, particularly lithium stearate.  The grease may also contain other additives such as antioxidants, particularly amino compounds, and extreme pressure agents containing sulphur, halogen and/or phosphorus. The complex soap may be formed by adding the C1-C5 monocarboxylic acid to the molten dihydroxystearic acid, neutralizing the mixture with boiling aqueous metal hydroxide solution and drying at temperatures below the fusion point of the soap, and the complex soap then added to the lubricating oil. Alternatively, oleic acid may be condensed with a hydroxylating agent, such as hydrogen peroxide, in a solution of the C1-C5 monocarboxylic acid and the monoester or diester of dihydroxystearic acid with the C1-C5 acid thus formed hydrolyzed and neutralized with the metal base to produce the complex soap.  Any unchanged oleic acid or any byproduct acids present will also be converted to soaps at the same time. If desired, the hydrolysis and neutralization may be carried out in the presence of a portion of the lubricating oil, if a nonsaponifiable lubricating oil is employed.  In the examples, lubricating greases are prepared from a complex lithium formatelithium dihydroxystearate soap together with (1) di-2-ethylhexyl sebacate and phenyl alpha-naphthylamine or (2) mineral lubricating oil, lithium stearate and phenyl alpha-naphthylamine.

Title: Improvements in or relating to reciprocating compressors
IPC: F04B49/24
Filed: 1927-05-12
Abstract: 276,623. Sulzer FrÞres Soc. Anon. Aug. 24, 1926, [Convention date]. Regulating and controlling compression.- In a reciprocating compressor in which the air is byepassed when the cylinder pressure is excessive, the valve of the bye-pass is provided with means lor lifting it from its seat, to relieve the cylinder compression, when starting up. The delivery pipe d or the cylinder a is connected by a pipe f with a valve chamber g from which there is a pipe connection back to the inlet pipe c. In the chamber g is a bye-pass valve e which is held on its seat by liquid pressure on a piston h, the pressure being maintained by a pump delivering to the pipe k. When the air pressure on valve e exceeds a predetermined value the valve lifts and bye-passes the compressor delivery back to the suction pipe c. The resulting movement of the piston h is transmitted to the spring controlled disc valve m, and the excess liquid flows away at l. For easy starting, the byepass valve c is relieved of the hydraulic loading by reducing the pressure of the spring n through movement of the control spindle o. The one control may simultaneously deal with each stage of a multi-stage compressor.

Title: The treatment of sewage
IPC: C02F3/12
Filed: 1960-04-11
Abstract: Raw sewage enters through pipe 10 and passes through a suitable grit chamber 11. If a primary settler is used in connection with this process, grit chamber overflow enters the primary settler and the overflow from the primary settler flows into an aeration tank 15 fitted with swing diffusers 16. Grit chamber effluent enters the tank 15 through a pipe 14, and is mixed with return sludge which is recirculated into the system from a splitter tank 24. After a period in the aerator the aerated mixed liquor overflows through a pipe 17 to a settling tank 18 where the suspended solids in the mixed liquor precipitate to form a sludge and clear effluent is discharged from the <PICT:0945678/C1/1> settling tank through conduit 19.  Sludge accumulated in the bottom of the settling tank 18 is moved to a sump 21 by means of a scraper 22.  Sludge is removed from the sump 21 by means of a conduit 23 and is conducted to a proportioning or splitter tank 24 by a pump 25 and a conduit 26.  The proportioning tank 24 is provided with an adjustable proportioning weir 27 adapted to make a suitable split in the flows to recirculation and waste disposal.  The loading rate of sewage, aeration volume, recycle waste sludge and recycle to incoming sewage ratios are specified.  Specifications 885,602 and 885,603 are referred to.

Abstract: 775,453. Attenuators. GENERAL ELECTRIC CO., Ltd., and HAYES, A. G. Dec. 14, 1954 [Dec. 17, 1953], No. 12957/54. Divided out of 775,452. Class 40 (8). A waveguide attenuator comprises a member 5 of ceramic, mica, plastic or other insulant carrying a resistive layer composed of either a number of mutually insulated separate areas of resistive material or a number of separate insulating areas between which there is resistive material. As shown, the resistive layer is in the form of a grid of resistive material the spacing between the insulating areas being small compared with the wavelength of the propagated energy, e.g. <SP>1</SP>/ 20  inch, where the cross-sectional dimensions of the guide are approximately 1.5 inch. The grid may be formed by a photographic process, e.g. as described in Specification 689,795 or Specification 573,798, [both in Group XXXVI]. Alternatively, the process described in Specification 652,630, [Group XL (a)], using a mixture of fish glue and ammonium or potassium dichromate may be used. The member 5 is movable laterally in the guide by means of a rod 4 extending through a side wall. Alternatively, it may be rotatable about its longitudinal axis. The invention may also be applied to attenuators of the type in which the resistive member extends into the guide through a slot in one of the walls. The attenuator may be used to suppress energy propagated in an unwanted mode or plane of polarization. The resistive layer may, for purposes of impedance matching, be non-uniform, e.g. in the manner described in Specification 775,452.
