Filed: 1935-11-15
Abstract: 465,881. Hair - curling. DOBSON, R. T. Nov. 15, 1935, No. 31673. [Class 131] A sachet, pad, or wrapper for use in waving or curling hair has formed integral with or attached to it an indicator treated with a chemical which, when the hair has been wetted and subjected to heat,-will be acted upon by the vapours evolved to give an indication of the progress of the treatment. It is explained in the Specification that hair of fine texture requires a more prolonged or more vigorous treatment than hair of coarse texture and three examples of solutions suitable for coarse, medium and fine hair are given: (1) À880 ammonia 2“ fluid ozs., sodium sulphite “ oz. ; (2) À880 ammonia 3 fluid ozs., sodium sulphite ¢ oz.; and (3) À880 ammonia 4 fluid ozs., sodium sulphite ¥ oz., triethanolamine salt of lauryl alcohol in liquid form “ dram, with water to 20 ozs. in each case. 1 Per cent. of a non-volatile acid such as citric acid may be added to reduce the pH value of the solution. With these solutions, a suitable chemical for the indicator would be 1-6 per cent phenol phthalein in alcohol. The indicator may comprise a paper backing for the sachet or a separate strip attached to the heater or paper wrapping and impregnated with the phenol phthalein. The indicator changes colour as the vapours are evolved and returns to its normal colour when the alkaline vapours have been disposed. To ensure a return to normal colour, the indicator may be impregnated with an acid which also serves to neutralize any small quantity of alkaline solution which might be splashed on it. According to the Provisional Specification, a solution for use with all kinds of hair may contain several constituents which boil at different temperatures, the vapours being of different acidity or alkalinity. The indicator in this case may contain a number of different constituents which respond to different degress of acidity or alkalinity.

Title: Improvements in or relating to deep frying
IPC: A47J37/12
Filed: 1955-11-09
Abstract: 821,027. Deep-fat frying apparatus. MITCHELL ENGINEERING Ltd. Nov. 9, 1955 [Nov. 10, 1954], No. 32081/55. Class 28 (1). Potato chips or the like are traversed through a receptacle containing hot liquid, e.g. oil, which is circulated extraneously, some or all passing through a reheating device, the liquid being removed adjacent the part of the receptacle from which the chips are removed and all or part of it being returned at a controlled rate to the receptacle adjacent the part to which the chips are fed, means being provided for controlling the circulation of the oil to control the temperature differential between the part of the receptacle where the comestibles are introduced from the part from which they are removed. Hot oil or the like is contained in a kettle 10 to which raw potato slices or the like are fed down shoot 11 and from which they are removed by a belt conveyer or the like 12. Oil is withdrawn from the end of kettle 10 adjacent the conveyer 12 through a pipe 13 by a centrifugal or other pump 14 which discharges the oil into heat exchanger 16. The oil passes from exchanger 16 in pipe 17 to three-way valve 18, one of whose other ports leads to the end of kettle 10 adjacent shoot 11 and the other of which is connected by a by-pass pipe 20 to the outlet pipe 13 of kettle 10. Valve 18 is controlled by a thermostatic control device 24 whose thermostatic element 25 is adjacent the discharge end of the kettle 10 so that some of the oil may by-pass the kettle. A heated medium is circulated through pipes 21, 22 to heat exchanger 16. A by-pass pipe 26 is also provided which leads from pipe 15 to a threeway valve 27 in pipe 17 controlled by a thermostatic control device 28 sensitive through element 30 to the temperature of the oil in pipe 17. Thus, normally valves 18 and 27 will be so arranged that the oil circulates from kettle 10 to exchanger 16 and back to kettle 10. However, if the temperature of the kettle rises above a desired predetermined level, valve 18 is actuated so that the oil flows through pipe 20 instead of pipe 19 and by-passes the kettle 10. In this event, if the oil again passes through heat exchanger 16 it may be at too high a temperature on reaching pipe 17 so valve 27 is actuated by thermostatic control 28 and part or all of the oil passes along pipe 26, thus bypassing heat exchanger 16. In a modification, Fig. 2 (not shown), by-pass 20 is omitted and valve 18 is replaced by a thermostatically controlled throttle valve.
