Patent GB-882942-A (GB)
Title: Improvements in or relating to thermostats
Inventor: USHERWOOD HARRY CHARLES FRANCI
IPC: H05B1/02
Filed: 1957-06-12
Abstract: 882,942. Automatic temperature control systems. GALLENKAMP & CO. Ltd., A. June 12, 1958 [June 12, 1957], No. 18565/57. Class 38 (4). A thermostat for controlling the temperature of a furnace, oven, heat bath or the like comprises two elements, 1, 20 which are liquid filled and connected to a bellows 2, the first element 1 being situated in the device to be heated whilst the element 20 is remote from the device and is provided with a heating member such as an electric heating coil 19, movement of the bellows 2 operating a micro-switch 5, the position of which is adjustable by means of a threaded spindle 11, ambient temperature compensation being provided by securing the bellows 2 to a member 14 which is supported on two further bellows 15. In operation, the device to be heated is heated electrically and the supply thereto and to the coil 19 is controlled by the switch 5. When the supply is switched on the coil 19 rapidly heats the element 20-which has little heat inertia-but the bellows 2 does not operate the switch 5 to remove the supply until the device is hot enough to cause the combined responses of the two elements 1, 20 to expand the bellows 2 to operate the switch. Upon removal of the supply the element 20 rapidly cools, whereupon the bellows 2 contract and the switch 5 operated to replace the supply. Thus the element 20 plays a predominant role ,in the control of the heated device and the temperature of the device is controlled within narrow limits. Slight variations in the response of the element 1 causes variations in the cycling of the element 20; the coil 19 of which may be wound for differing wattages. In an alternative arrangement the heating of the device and the element 20 may be done by gas burners and the elements 1, 20 may comprise metal rods only, either solid or tubular.

Abstract: The invention comprises new di-(aryloxazolyl)-derivatives of formula <FORM:0835894/IV (b)/1> in which R1 and R2 indicate aryl residues condensed with the hetero ring as shown.  These and other compounds, all of the general formula <FORM:0835894/IV (b)/2> in which R1 and R2 are as above and R3 is -CH=CH-group or a -CH=COH-group, may be manufactured by heating acylamino compounds of the general formula <FORM:0835894/IV (b)/3> in which R1 and R2 are aryl groups having the -OH and -NH- groups attached to adjacent carbon atoms and <FORM:0835894/IV (b)/4> or a <FORM:0835894/IV (b)/5> group, with agents that split off water.  Suitable agents for splitting off water are, for example, boric acid, propionic acid, glacial acetic acid, sulphur trioxide and, particularly, zinc chloride.  When sulphur trioxide, advantageously in the form of oleum, is used, sulphonation of the aromatic nuclei may also take place.  The enolic group -CH= COH- which occurs in some of the compounds referred to above may exist in the tautomeric form -CH2-CO- and both enol and keto forms are included in the definition of R3.  The acylamino compounds used as starting materials may be prepared according to the process described and claimed in Specification 835,893, in which malic acid or tartaric acid is condensed on both carboxylic acid groups with primary aryl amines that contain an hydroxyl group in adjacent position to the amino group.  The R1 and R2 groups are preferably benzene nuclei which may contain as substituents low alkyl or alkoxy groups containing up to 4 carbon atoms, halogen atoms or nitro groups.  In the examples the following compounds are prepared: <FORM:0835894/IV (b)/6> <FORM:0835894/IV (b)/7> <FORM:0835894/IV (b)/8> <FORM:0835894/IV (b)/9> <FORM:0835894/IV (b)/100> or its tautomer <FORM:0835894/IV (b)/111> <FORM:0835894/IV (b)/122> and (g) the sodium salts of <FORM:0835894/IV (b)/133> and <FORM:0835894/IV (b)/144>ALSO:The invention comprises new di-(aryloxazolyl) derivatives of formula <FORM:0835894/IV(c)/1> in which R1 and R2 indicate aryl residues condensed with the hetero ring as shown. These and other compounds, all of the general formula <FORM:0835894/IV(c)/2> in which R1 and R2 are as above and R3 is -CH = CH- or -CH = COH- may be obtained by heating acylamino compounds of formula <FORM:0835894/IV(c)/3> in which R1 and R2 are aryl groups having the -OH and -NH- groups attached to adjacent carbon atoms and R4 is a <FORM:0835894/IV(c)/4> group, with agents that split off water, e.g. boric acid, propionic acid, glacial acetic acid, sulphur trioxide and, particularly, zinc chloride.  When sulphur trioxide is used, sulphonation of the aromatic nuclei may also take place.  The aromatic nuclei R1 and R2 may contain as substituents alkyl or alkoxy groups containing up to 4 carbon atoms, halogen atoms or nitro groups.
