Patent GB-963739-A (GB)
Title: Process and apparatus for the production of flavoured cereals
IPC: A23L27/00
Filed: 1959-11-09
Abstract: A flavoured grain cereal for example rice, wheat or barley, is produced by providing the outer surface of the grains with a coating of a desired flavouring, covering the coated grains with an envelope of flour obtained or formed from the cereal grain breakage, whereby the grains remain separated from one another, and finally surrounding the envelope with a thin film of hydrogenated fat to delay moisture absorption by the flavoured cereals thus produced.  Crude cereal grains may be covered with a mix consisting of an edible saturated fat and a flavouring extract, and then coated with the envelope of flour and the thin film of hydrogenated fat.  A savoury flavouring may be applied in a finely ground or flaked condition to puffed grains coated with a glucose syrup, and the flavouring is then covered with glucose syrup before enveloping the grains in the breakage flour and coating with the hydrogenated fat; the flavoured cereal grains produced are then rapidly cooled to a temperature between 0 DEG  and 5 DEG  C.  A colouring agent may be added to the flour forming the flour envelope.  Flavourings mentioned: apple syrup, lemon, orange, apricot, raspberry, strawberry, tomato powder, chicken paste, cheese, salted fish, curry, dehydrated onion or garlic, herbs such as mint, thyme, laurel and oregans, and sodium glutamate.  Examples are disclosed.

Title: Improvements in clothes drier
IPC: D06F34/18
Filed: 1961-10-24
Abstract: 965,297. Measuring thermal conductivity electrically. ROBERTSHAW-FULTON CONTROLS CO. Oct. 24, 1961 [Oct. 24, 1960], No. 38090/61. Heading G1N. The rate of loss of heat and hence the resistance of a temperature sensitive resistor located in and thermally insulated from the rotating drum of a clothes drier and heated by an electric current to a temperature above that of the air used for drying, is determined by the moisture content of the fabric with which it comes into contact. As shown, a thermistor 18 (Fig. 2,) in a moisturesensing probe 1 (Fig. 3,) located in a drier drum 26, and a thermistor 19 in a temperature-compensating probe 1 subject only to the heating air and mounted on the drier frame 28, are connected in a bridge circuit with a centre tapped transformer 16, the bridge output varying with fabric moisture content so that when it reaches a predetermined value, a thyratron 14 triggers and operates a relay 24 to switch off the drier. Each thermistor comprises a cylindrical semi-conductor element 9 (Fig. 1,) located in a tip portion 4 of a pedestal 2 from which the tip is thermally insulated by a spacer 5 made from e.g. nylon. The element 9 is soldered to the tip 4 so as to provide a mutual heat conductive path, the rest of the element surface being spaced from its housing 10 so as to be electrically insulated. To ensure that heat from the tip 4 is conducted rather than radiated its surface is brightly plated, and the heat flow between the element 9 and its housing 10 is optimised by coating the inside of the housing with heat absorbent material. Electrical connections are brought out through lead 11 soldered to the element 9 and one soldered to a securing bolt 6 if this is metal, or by a separate lead soldered to the tip 4 if the bolts are of insulating material.

Title: Production of oil from solid carbonaceous materials
IPC: C10G1/00
Filed: 1962-10-15
Abstract: Oil and water are separately recovered from the vapours obtained by the thermal treatment of solid carbonaceous materials by first condensing and separating hydrocarbons boiling above 650 DEG  F. leaving a vapour containing steam and condensing steam together with an oil fraction, which is separable from the water without the aid of external expedients and which is at least partly combined with the first oil fraction, leaving a light hydrocarbon vapour. Preferably the first condensation is effected in a fractionating column 2 from which is recovered the steam/hydrocarbon vapours by line 3 preferably leaving condensed hydrocarbons boiling above 500 DEG  F. recovered in four fractions by lines 5, 8, 13, and 18.  The first passes to absorber 70, the second is partly cooled and returned to the column by line 10, the third is also partly cooled and returned by line 15 and the remainder of these fractions together with the fourth, from which solids have been separated, are used to supply heat to absorber 70 and recovered in line 76.  The overhead vapours are cooled at 4 to 60-180 DEG  F. and separated into water, passed for purification at 90, a liquid hydrocarbon fraction in line 37 partly returned to fractionator 2 and partly passed to absorber 70, and vapours in line 33 which are compressed and partly recycled by line 36 and partly cooled and passed to separator 50.  Water is recovered by line 56 and liquid and vaporous hydrocarbons by lines 55 and 51; these latter are combined and passed to absorber 70 where all C3+ hydrocarbons are absorbed and recovered in line 72 for combining with oil in line 76 while fuel gas is recovered in line 71. <PICT:0966154/C4-C5/1>
