Title: Improvements in or relating to automatic warning devices
IPC: F23L15/02
Filed: 1935-09-27
Abstract: 452,741. Automatic warning devices. GREENFIELD, G. J., Butterthwaite, Ecclesfield, near Sheffield. Sept. 27, 1935, No. 26766. [Class 51 (i)] A device for giving warning of the non- recurrence of a mechanical operation which is intended to recur at regular intervals or cycles of two different intervals, such as the reversal of the flow of fuel and air supply to regenerative furnaces, consists of two interconnected vessels one of which is caused by the mechanism performing the operation to take up alternately a higher and a lower position than the other thereby allowing a liquid to run alternately from one vessel to the other and back again, the excess of liquid flowing into one of the vessels when the recurring operation fails to recur being adapted to actuate a visible, audible or other signal. At each mechanical operation a vessel 1 is moved from a higher to a lower position or vice versa and liquid flows through a tube 3 from or to the stationary vessel 2 to or from the moveable vessel 1. Should the operation fail to be performed at the proper time a float 5 in the vessel 2 closes electric contacts 9, 10 or 9, 11 and actuates through a relay 12 or otherwise a warning device. Excess water in either of the vessels may return to the other vessel through a tube 13. The rate of flow of liquid from one vessel to the other may be regulated by a constriction in the tube 3. The overflow level of the liquid in the vessels may be adjusted by a swivelling tube 19 as shown in Fig. 2 or by tubes 22 of different length, as shown in Fig. 3. The apparatus may be adjusted so as to operate with two successive pauses of different duration between the times of operation of the main mechanism, for example, by adjusting the electric contact 9. Instead of vessels 1, 2 of the form shown, the vessel 1 may be wide and shallow and the vessel 2 tall and narrow or the vessel 1 may be narrow at the middle and wide at the top and bottom while the vessel 2 is wide at the middle and tapering towards the top and bottom. The vessel 1 may be suspended at various distances from the centre of the rotating member on which it is supported or at different points at or near the periphery thereof. The float may be disposed in the movable vessel or there may be a float in each vessel. Both vessels may be moveable. Instead of electric means for operating the warning device, mechanical means to release a catch may be provided to set in action a falling weight. When mercury is used in the vessels, the float may be dispensed with and the vessel 2 may be supported resiliently and operate a warning device.

Title: Improvements in or relating to beta-thio-carboxylic acid compounds and method of preparing the same
Filed: 1946-09-06
Abstract: In the process of the parent Specification in which salts of b -substituted carboxylic acids are obtained by reacting saturated aliphatic b -lactones of the general formula <FORM:0639679/IV (b)/1> wherein R1, R2, R3 and R4 are hydrogen atoms or alkyl groups, with inorganic salts ionizable in a polar solvent reaction medium, the ionizable salts used are inorganic sulphides and b -thiocarboxylic acid compounds are thereby produced.  Sulphides instanced are hydrogen sulphide, ammonium sulphide or hydrosulphide, alkali metal sulphides or hydrosulphides, e.g. sodium and lithium hydrosulphide, sodium and potassium sulphide and alkali earth metal sulphides and hydrosulphides.  Preferably, hydrogen sulphide is passed through an aqueous or alcoholic solution of a base or sulphide and the b -lactone added thereto.  On acidification a mixture of a b -mercapto-carboxylic acid and a b -thio-dicarboxylic acid is obtained which may be separated by e.g. distillation.  It is stated that when hydrosulphides are used, more of the mono-carboxylic acid is produced than of the dicarboxylic acid, the reverse being the case when sulphides are used.  Hydrogen sulphide may be passed into solutions of the lactone or solutions of hydrogen sulphide used in which case the use of pressure is generally necessary.  b -Propiolactone is the preferred lactone. In examples, b -propiolactone is added to a solution obtained by passing hydrogen sulphide into (1), (2) and (3) aqueous sodium hydroxide, (4) alcoholic sodium hydroxide and (5) aqueous sodium sulphide to produce on acidification b -mercapto-carboxylic acid with some b -thiodicarboxylic acid and in (6) b -propiolactone is added to aqueous sodium sulphide and the same two acids obtained on acidification although the total yield is much smaller and the b -thio-dicarboxylic acid preponderates. Specification 649,028 is referred to.  The Specification as open to inspection under Sect. 91 is not restricted to the use of aliphatic saturated b -lactones, but also specifies lactones of b -hydroxy-monocarboxylic acids containing cycloalkyl, aryl and aralkyl substituents, lactones of unsaturated b -hydroxy-carboxylic acids, mono- and di-b -lactones of dicarboxylic acids and b -lactones containing oxygen, nitrogen, sulphur and halogens combined in such groupings as nitro, ether, amino and hydroxy as well as the carbonoxy structure and hydrogen atoms.  This subject-matter does not appear in the Specification as accepted.

Filed: 1974-06-19
Abstract: 1471949 Upgrading carbonaceous material SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 19 June 1974 27190/74 Heading C5G Coal or the like (defined below) is upgraded by forming a pumpable aqueous dispersion of finely divided coal or the like, pressurizing the dispersion at below 100 C., and thereafter heating the pressurized dispersion at at least 150 C. to effect a coalification of the coal or the like, the dispersion being pressurized to a pressure above the water vapour pressure at the coalification temperature. The term " coal or the like " is defined as comprising coal, brown coal, peat and similar high carbon content materials of like nature. Prior to separation from the water and during or after the heating step, the dispersion may be agitated in the presence of a water insoluble binder (e.g. light hydrocarbon) resulting in a dispersion of agglomerates of carbon containing material in water. After separation from the water, and possibly after grinding the agglomerates, the binder may then be separated from the agglomerates by evaporation, e.g. in a fluidized bed using as the fluidizing gas either the binder in the vapour state or inert gas.

Abstract: 1455576 Microcapsules WIGGINS TEAPE Ltd 30 May 1974 [7 June 1973] 27281/73 Heading B8C A method of producing individual mononuclear oil-containing microcapsules comprises emulsifying an oil in a solution of a gellable hydrophilic colloid (e.g. an aqueous solution of gelatin), adding a solution of carboxymethyl cellulose to the emulsion, effecting complex coacervation so as to form mononuclear microcapsules each comprising a droplet of the oil as a nucleus with a wall of the colloid material and carboxymethyl cellulose around the nucleus, and gelling the microcapsule walls, the dry weight ratio of the colloid material to active content of the carboxymethyl cellulose used being between 1 : 0À35 and 1 : 1À2. The use of methyl cellulose and carboxymethyl cellulose in a ratio of 1 : 1, and also the use of gelatin and carboxymethyl cellulose in a ratio of 1 : 0À5, are disclaimed. The oil may be a mineral oil (e.g. kerosene) or a synthetic oil such as alkylated diarylmethanes, di-isopropyl naphthalene, mono-isopropyl biphenyl, dibenzyl benzenes, heptyl undecyl phthalate, alkylated diarylethanes and alkylated benzenes. Kerosene of alkylated benzene may be used as diluents for other synthetic oils and in the examples partially hydrogenated terphenyl diluted with kerosene is employed. Complex coacervation is effected in the examples, after adding carboxymethyl cellulose to the emulsion of oil in aqueous gelatin solution, by lowering the pH of the mixture from 7À5 to 4À4 by addition of acetic acid, followed by cooling of the mixture from 55 to 10 C. Glutaroldehyde solution is then added, the mixture stirred overnight, the pH then raised to 10 by addition of sodium carbonate solution and finally forwaldehyde solution is added. The oil employed may contain dissolved dye and the microcapsules produced may be coated on to a paper base for use in a pressure-sensitive copying system.
