Title: Improved lubricating oil compositions
Inventor: DAVIES ROY TREVOR
IPC: C10M135/04
Filed: 1953-05-15
Abstract: A solution in a mineral lubricating oil of the reaction product between a terpene and elemental sulphur is steam-distilled at a temperature below the decomposition temperature of the sulphurized terpene, thereby removing the lower-boiling constituents of the solution and rendering the solution substantially odourless.  The sulphurization may be conducted in the presence of mineral lubricating oil and, if desired, in the presence of a sulphurization catalyst such as tetramethyl thiuram disulphide, mercaptobenzothiazole or diphenyl guanidine. Sulphurization may be followed by blowing with an inert gas.  In an example, sulphurized dipentene in mineral lubricating oil solution is steam-distilled. Specification 688,293 is referred to.ALSO:A solution in a mineral lubricating oil of the reaction product between a terpene and elemental sulphur is steam-distilled at a temperature below the decomposition temperature of the sulphurized terpene, thereby removing the lower-boiling constituents of the solution and rendering the solution substantially odourless.  Lubricating compositions may be prepared by blending a solution, treated in this manner, with further lubricating oil, particularly mineral lubricating oil. Minor proportions of detergents may also be added to the lubricating compositions.  Suitable detergents are calcium mahogany sulphonates, calcium or barium phenates, zinc butyl or isopropyl benzoate, metal organo-phosphates and -thiophosphates, and alkaline earth derivatives of alkyl phenol sulphides or of sulphurized alkylated phenols, for example sulphurized barium p-iso-octyl phenate.  These last-mentioned alkaline earth derivatives may be employed in conjunction with calcium or barium mahogany sulphonates. In an example, a solution of sulphurized dipentene in mineral lubricating oil is steam-distilled, and a lubricating composition is prepared from the steam-distilled solution by blending it with more lubricating oil and barium octyl phenyl sulphide.  For comparison purposes, similar lubricating compositions are described in which the sulphurized dipentene is either added in its crude form or after steam distillation in the absence of mineral lubricating oil. Specification 688,293 is referred to.

Filed: 1923-05-25
Abstract: 198,367. Soc. Anon. Calor. May 29, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Switches partly electromagnetic; thermal switches; springs, arrangement of.-A switch, operated by changes in temperature, comprises a permanent or electromagnet acting in opposite directions on a soft iron lever e, articulated at one end f and carrying at its free end a contact k which engages a fixed contact l. The lever e is acted on by a rod d actuated by a membrane b through springs h, h<1> and adjustable nuts i. Excess temperature acts on the membrane b to raise the rod d and stress the lower spring h<1>, and at a given temperature the lever e is forced away from the pole j<11> into the field of the pole j<1> which attracts it, thereby opening the switch. When the membrane retracts, assisted by its spring r, the spring h acts to re-close the switch in a similar way. With suitable modification, the device may be adapted for use as a fire alarm.

No. 57 to 71, Ch is S, Se or Te and 0À001#x#0À2. There is preferably at least one of the oxychalcogenide phosphors. Many phosphors and phosphor combinations are disclosed. A screen may comprise a supporting base (opaque or transparent), a light reflecting layer, the phosphor layer and a protective layer, the light reflecting layer may be of baryta or titanium dioxide in polymeric binder or a thin film of Al or Ag (evaporated), and need not be present between the base and phosphor layer if the former is polyester, but may be on the other side of the support or separated therefrom. Also exemplified are phosphor proportions, phosphor/binder ratios, phosphor particle sizes (1-40 Á), phosphor coating wts., plasticizers, dyes or pigments for at least one of the phosphor, protective or light reflecting layers to increase sharpness by reducing light scatter and reflection, base and protective layer materials. Binders may be cellulose esters (e.g. cellulose acetate, triacetate, acetate butyrate, and nitrate) polyvinyl compounds (e.g. p.v.c. and polyvinyl butyral) and copolymers of vinyl compounds and solvent soluble polyesters. The screens may be a pair on each side a double coated X-ray film, or a single screen contacting a single sided X- ray film for mammography. The film may be sensitive to blue, or green and blue light, a green sensitive film being preferred for screens with one or more green emitting phosphors for maximum exposure reduction. Mottle reduction is also achieved. Detailed examples are included. Screens with barium fluorochloride and yttrium oxysulphide reduce exposure requirements by one quarter relative to conventional calcium tungstate screens, thus facilitating their introduction into clinical use.
