Abstract: 478,952. Indicating rate of ascent and descent of aircraft. KOLLSMAN, P. June 24, 1936, No. 17531. Convention date, June 28, 1935. [Class 106 (ii)] The speed of rise and fall of an aircraft is shown respectively on scales 4, 5 of a dial 2 by a pointer 3 actuated by a diaphragm B subjected on one side to the static pressure from a Pitot-tube by means of pipes 9, 8, the other side of the diaphragm being connected by a narrow pipe 6 to a vacuum-walled air container C having an automatic temperature-compensation valve 16 controlling the passage of air into the container C, which communicates with the pipe 9 by a moisture filter D and ducts 11, 10. The valve plate 16, which has a curved edge 18 serving to vary the restricted air connection 15 of the duct 11 with the chamber C, is automatically adjusted in position by expanding capsules 27, 28 containing gas under low pressure and housed in the chamber C. The mechanism for actuating the pointer 3 by the diaphragm B includes a rock-shaft 62 for a multiplying lever 63, one bearing 78 of the rock-shaft being movable by a thumb-screw 71 to compensate for local temperature conditions.

Melt 3 in the ladle 1 is forced into the tundish 13 through an ascending tube 12 by gas pressure in a housing 15. The tube 12 is connected to the melt entry tube 18 of the tundish by a water-cooled sleeve 26 and slide valve. The tundish is filled with inert gas through a port 24 and evacuated during pouring. The melt leaves the tundish through a down-tube 20 provided with a stopper 21 to enter the mould 31. The normal working level of the melt in the tundish is at 38, but when ladles are to be changed the tundish is filled to level 39, the valve 25 closed and the tundish raised by a piston and cylinder 29 to a position where the downtube lower end still lies below the surface of the melt in the mould 31. The ladle in its housing can then be rolled away. For easy access to the mould during maintenance and during relining the tundish, the tundish 13 is rotatably mounted on bearings 30. In Fig. 8 the pouring of a rimming steel with concomitant degassing of the steel in the tundish is shown. The tundish is connected to a vacuum pump at 49 and a spray of steel is emitted from an inclined port. The down-tube 20 is in two sections, the lower 20a being flared and of a molybdenum/zirconium oxide cermet. A cover 65 for the mould is provided and argon is supplied through a duet 66 to the mould.

Abstract: Compositions for making detergent bars or tablets contain a major proportion of soap and minor proportions of (1) a non-ionic detergent and (2) a non-ionic nondetergent compound, as specified below, with or without (3) an anionic non-soapy detergent.  The non-ionic detergent may be a condensation product of ethylene oxide or propylene oxide with a long-chain alkylphenol, e.g. octylphenol, or with a long-chain fatty alcohol, e.g. lauryl alcohol, or with a long-chain fatty acid, e.g. oleic or stearic acid, or with a long-chain fatty acid partial ester of a polyhydric alcohol, e.g. sorbitan monolaurate or trioleate.  The non-ionic non-detergent compound contains a hydrophobic group, generally of 9-18 carbon atoms, and a hydroxy or amido group, and is only sparingly soluble in water.  Suitable compounds are (a) compounds of the formula RArOH, where R is an alkyl radical of 3-10 carbon atoms and Ar is a benzene nucleus, which may be further substituted, e.g. p-n-hexylphenol or 2-n-octyl-4-chlorophenol, (b) compounds of the formula RArOR1OH, where R and Ar are as above and R1OH is a polyhydric alcohol residue e.g. p-n-propylphenyl-a -glycerol ether, 2, 6-dichloro - 4 - tert. - octylphenyl - a  - glycerol ether p-cyclohexylphenyl-a -glycerol ether, o-n-octylphenyl-monoethylene glycol ether, or the p-tert.-octyl phenyl ether of diethylene glycol or triethylene glycol, (c) partial esters of polyhydric alcohols containing 2-6 hydroxy groups with fatty acids of 10-18 carbon atoms, e.g. glycol mono-oleate, glycerol monopalmitate or sorbitan monolaurate, (d) saturated or unsaturated fatty alcohols of 10-18 carbon atoms, e.g. lauryl or oleyl alcohol, and (e) amides or alkanolamides of fatty acids of 10-18 carbon atoms, e.g. lauric acid amide, glycerolamide, monoethanolamide or monopropanolamide.  Suitable anionic non-soapy detergents are (a) sulphated long-chain primary alcohols, e.g. sodium lauryl sulphate, (b) secondary alkyl sulphates, e.g. those obtained by the sulphation of olefines, (c) esters of sulphosuccinic acid, e.g. dioctyl sulphosuccinate sodium salt, and (d) alkylaryl sulphonic acids, e.g. dodecylbenzene sulphonic acid.  The minimum proportion of non-cationic non-soapy detergent is 15 per cent, and the maximum proportion of non-ionic detergent is 40 per cent unless an anionic detergent is also present, in which event the maximum proportion of non-ionic detergent is 30 per cent and the minimum proportion is 3 per cent when the anionic detergent is of the sulphuric ester type and 8 per cent when the anionic detergent is of the sulphonate type. Examples are given, and Specification 733,416 is referred to.
