Title: Improvements in and relating to anti-rachitic wheat germ flour
IPC: A23L7/152
Filed: 1962-11-28
Abstract: In producing purified, anti-rachitic wheat germ flour from a mixture of wheat germ and chaff obtained as a by product during flour milling, the mixture is partially dehydrated, at a temperature not exceeding 35 DEG C., e.g. in a dry atmosphere with the acid of one or more dehydrating agents having no deleterious effect on the wheat germ, or by being heated, as by infra-red rays, if desired, under reduced pressure.  The partially dehydrated mixture is then ground, e.g. between substantially smooth steel rollers or vertical or horizontal millstones, so that the wheat germ is reduced to flour and the chaff remains intact.  The resulting flour is then screened, e.g. through a nest of four silk screens having successively diminishing mesh apertures, to remove the chaff as overs and yield the purified wheat germ flour as unders, e.g from the lowest and finest silk screen.

Title: Anthraquinone derivatives
IPC: C09B1/52
Filed: 1964-11-05
Abstract: The invention comprises 5,8-diamino-1,4-hydroxy-anthraquinone compounds which are substituted in the 2-position by a chlorine atom or by a p-phenolic or p-phenolic alkyl ether group and which compounds may be monosubstituted in the amino groups by alkyl or aryl radicals.  The dyes are obtained by treating the diamino-dihydroxy-anthraquinone in sulphuric acid solution or suspension in presence of an oxidizing agent to produce the corresponding di-imine compound which is then treated with HCl or phenol or a phenolic alkyl ether under the same conditions after which reduction to the diamino compound, if necessary, is preferably effected using sodium bisulphite.  The dyes may contain sulphonic acid groups, and provide blue-green shades.  Reference has been directed by the Comptroller to Specification 834,518.ALSO:5,8-diamino - 14,-dihydroxy-anthraquinones which are substituted in the 2-position by a chlorine atom or a phenolic or alkyl phenyl ether group and which may be substituted in one or both amino groups by alkyl or aryl groups are used to dye polyesters, polyamides of triacetate when no sulpho group is present and for wool when a sulpho group is present.  In Example 1 polyester fibres are dyed at 96-98 DEG C. with a dye of the above type to give a green-blue shade. Reference has been directed by the Comptroller to Specification 834,518.

Abstract: 1,105,908. Automatic temperature control of heating pads. INDOHEEM N.V. Nov. 11, 1965 [Nov.12, 1964], No.48002/65. Heading G3R. A system for controlling the temperature of an electric heating pad, the heating element of which is in the form of heating resistor 1 surrounded by two concentric conductors 2, 3 connected together at one end by a diode 4 and a negative temperature coefficient resistor 5 located in the pad and at the other end by a bi-metallic device 13, 14, a relay winding 10 and the secondary winding 12 of a transformer, the contacts 8, 9 of the relay operating in a cyclic fashion to maintain the temperature of the pad at a desired value. The initial operation of the relay 10 must be arranged by an external means (e.g. a push button) to close contacts 8, 9 the heating resistor 1 then being energized by way of the primary winding 11 of the transformer. The voltage induced in the secondary winding 12 then energizes the relay winding 10 over the diode 4, temperature sensitive relay 5 and bi-metallic device 13, 14. As the pad temperature increases the resistance of the resistor 5 decreases thus increasing the current through the heating element 15 until the contact 14 opens to de-energize the relay winding 10 opening contacts 8, 9. A small current then flows through a circuit comprising resistors 15, 16, 17, winding 11, heating resistor 1 and resistor 18 such that a capacitor 20 is charged over a diode 19 by the volt drop across resistor 16. When the bi-metallic device cools sufficiently to allow contact 14 to close, capacitor 20 discharges through the relay winding 10 whereupon contacts 8, 9 close to repeat the cycle. Any defect or fault in the pad such as a short circuit between the conductors 2, 3, or between the resistor 1 and the conductor 2 or an open circuit in the resistor 1 will prevent energization of the relay winding 10. The values of the resistors 15-18 are such that, with contacts 8, 9 open, only a small voltage exists across the resistor 1.
