Title: Improvements in apparatus for indicating when the water in a steam generator or the like has fallen to a predetermined low level
IPC: F22B37/42
Filed: 1924-06-21
Abstract: 235,012. Fredriksen, H. A. June 21, 1924. Ball and float valves; closure members. - A float-operated valve 5 supplying steam to a whistle 16 for indicating low levels in steam generators is supported upon an internal pipe 3 carrying a ported guide 10 for the hollow float stem 7. The valve 5 is adapted to close the pipe 3 when the water level and float are up. When the level falls unduly, the valve opens and steam operates the whistle. For preventing steam from keeping the valve off its seat when it should be nearly closed, it has a hollow cylindrical projection 21 with ports 22 in it, and it also has an inverted conical projection 23 whereby the steam flowing past it tends to take the weight of the valve and float, and also counterbalances, in the direction of closure, unbalanced pressure on the float and valve.

Abstract: 586,762. Coating or impregnating fabrics. ANGUS & CO., Ltd., G., SOWERBY, G. A., and SHORT, W. S. Aug. 16, 1944, No. 15649. [Class 140] A friction surface belt consists of a strip of knitted fabric stretched to straighten the yarns and impregnated with rubber so as to prevent contraction of the fabric from its stretched length.. The rubber may be allowed to solidify in the interstices of the fabric from a wet, liquid or plastic condition, or the fabric is impregnated with rubber latex or rubber solution which is allowed to dry whilst the fabric is stretched or alternatively the latex is coagulated; or the fabric may be impregnated with rubber latex or rubber solution which is allowed to dry, warmed to soften the rubber, the fabric stretched while the rubber is plastic and maintained so stretched until the rubber has cooled and set. In each case, the rubber may be subjected to curing under heat and pressure. The amount of stretching is such that the extension at break of the finished product is 3-17 per cent. The fabric belting, e.g., of flax or cotton, is dropped into a bath of latex or rubber solution and when throughly wetted is passed over spiked rollers, the second pair of which rotates at a higher speed, and either through an oven in which it is dried or in the case of latex through a bath of acid or alcohol to coagulate the latex. Single or multi-ply belting may be treated, the lamination being effected either before or after the impregnation and stretching treatment. Joining of the belt is done by hand knitting, by chamfering and lapping under heat and pressure, or by the use of standard fasteners. Specifications 469,797, [Group V], and 586,786 are referred to.

Title: Improvements relating to the extraction of phenols from coal-tar hydrocarbons
Inventor: CUMMING ALFRED PATON COLEMAN
IPC: C07C37/72
Filed: 1952-06-20
Abstract: Phenols, i.e. phenol itself and other compounds having one or more hydroxyl groups attached to a single aromatic nucleus and homologues thereof having alkyl groups attached to the aromatic nucleus, are separated from hydrocarbons, e.g. aromatic, paraffin or naphthene hydrocarbons, with which they are mixed by using glycerol, ethylene glycol, diethylene glycol or tri-ethylene glycol as a preferential solvent for the phenols.  The process may be applied to mixtures of phenols and hydrocarbons, substantially free from bases or to mixtures, such as the neutral oil from a coaltar fraction, which contain both phenols and bases.  Mixtures in which a substantial part of the phenolic content is phenol such as for example a mixture of 70 per cent hydrocarbon and 30 per cent of phenols composed of 45 per cent phenol, 15 per cent o-cresol, 21 per cent m-cresol and 14 per cent p-cresol may suitably be extracted with glycerol, or in the case where a substantial part of the phenolic content comprises cresols, the solvent may suitably be an aqueous, e.g. 63 per cent solution of tri-ethylene glycol.  A preferred process comprises treating the mixture with the solvent, e.g. by countercurrent extraction, to give an extract rich in phenols, distilling off the solvent from the extract preferably under reduced pressure and steam-distilling the extract to give a mixture of phenols and water from which the water is removed by steam distillation. Alternatively, the mixture of phenols and water from the steam distillation may be separated into an aqueous fraction containing phenols, and a phenol fraction which may contain over 20 per cent of hydrocarbon oils.  The aqueous phase may be extracted with hydrocarbon oils to recover the phenols, the resulting mixture of phenols and hydrocarbons being returned to the solvent extraction stage.  Similarly the phenolic phase containing hydrocarbon oils may also be returned to the extraction stage.  A continuous process for separating phenols and hydrocarbon oils is described.
