Title: Improvements in or relating to electrical thermal storage space heaters
IPC: F24H9/20
Filed: 1964-04-13
Abstract: 1,065,662. Thermal storage space heaters. WITTE HEIZTECHNIK G.m.b.H. April 13, 1964 [April 27, 1963], No. 15253/64. Heading F4U. An electrical thermal storage space heater comprises an upwardly directed conduit 6 outside the core 3 but within its region of thermal influence communicating at both ends with the surrounding atmosphere and containing a thermo-sensitive element of a thermostat which controls the heater output. In the embodiment the thermostat 10 is disposed within the lower part of the conduit 6 and its response temperature is set by manual switch 12 through a chain or cord 11 or a shaft (13) and bevel gears (15). Air from the inlet 5 and distributing chamber 4 is passed through the core by a fan. The small amount of heat reaching the conduit 6 from the core causes a convection air flow from inlet 9 through the conduit 6 and over the thermostat 10 to the outlet 8, the thermostat controlling the fan. The thermostat may be protected from direct heating from the core by a shield, e.g. by a baffle on the side facing the storage core or by a tubular baffle.

Patent GB-565593-A (GB)
Title: Improvements in or relating to the preparation of metal salts of alkyl or cycloalkylsalicylate sulphides
Filed: 1942-11-02
Abstract: Metal salts of the formula <FORM:0565593/IV/1> in which R1 and R2 are alkyl or cycloalkyl radicals of 4 or more carbon atoms, n is 1 or 2, M is a metal radical, and X its valency, are prepared by treating an ester of the formula <FORM:0565593/IV/2> with a metal oxide or hydroxide.  These esters are made by reacting an aliphatic or cycloaliphatic ester of salicyclic acid with half the molecular equivalent of S2Cl2, SCl2 or SOCl2 in presence of a Friedel-Crafts' catalyst, e.g. AlCl3, SbCl5, FeCl3, TeCl2, SnCl4, TiCl4, TeCl4, BiCl3 or ZnCl2, generally in a solvent such as carbon disulphide, ethylene chloride, petroleum naphtha and nitrobenzene.  The product is acidified and extracted, for example with toluene.  The metal salts may be obtained by addition of a metal oxide or hydroxide of sufficient basicity such as those of the alkali and alkaline-earth metals.  Salts of less basic metals can be prepared by double decomposition of a compound of the metal and, preferably, sodium salicylate sulphide.  Metals specified are Al, Pb, Mg, Zn, Ca, Ba, Sr, Na, K.  R1 and R2 may be butyl, normal or tertiary amyl, ethyl hexyl, normal octyl, decyl, dodecyl, hexadecyl, octadecyl, cyclopentyl, cyclohexyl or methyl, ethyl, propyl, butyl or amyl, mono-, di- or tri-substituted cyclohexyl.  In an example, dodecyl salicylate and sulphur dichloride are heated together at 60-70 DEG C. in naphtha with AlCl3 as catalyst, the dodecyl salicylate monosulphide formed being extracted with toluene and neutralized by heating with barium hydrate in ethyl alcohol and toluene to yield the barium salt which is isolated by evaporation of the solvent under reduced pressure.  The metal salts are used as detergents and corrosion inhibitors in lubricating oils.  From 0.1 to 0.8 per cent is sufficient for ordinary purposes, but for extreme pressure lubricants 0.5 to 3.0 per cent is generally used. 50 per cent or more may be added to lubricating oils for storage and blending purposes. The salts have a solubilising action on other detergents and the like, e.g. dithiophosphates such as di-(p-tertiary amyl phenyl) dithiophosphate, and stearates, palmitates and naphthenates of Ca, Ba, Al, Zn and Mg, so that increased amounts of these compounds may be added.  The results of a test, wherein a solvent-refined oil containing 0.4 per cent of barium dodecyl salicylate monosulphide is air treated while heated in the presence of copper-lead alloy strips are compared with those for the oil alone.
