Title: Improvements in and relating to thermographic printing
IPC: B41M7/02
Filed: 1959-06-10
Abstract: An embossing compound for use in thermographic relief printing is prepared by mixing metallic pigment with granules of a resin conventionally employed in thermographic relief printing, raising the mixture to a temperature below the true sintering point of the resin and maintaining this temperature until the metal and resin particles adhere to one another and there is slight caking or incipient sintering of the mixture.  Metallic pigments are bronze and aluminium powders, and resins mentioned are coumaroneindene resins; and a mixture of coumarone resin, natural or synthetic wax and isomerized rubber resin.  The size of the resin granules depends on the size of printing type, e.g. for bold print 60-80 mesh; medium 80-150 mesh, fine 150-200 mesh and extra fine 200-300 mesh.  The proportion of pigment in the mixture will also depend on the particle size of the resin. Typical proportions for bronze or "gold" pigment are:-coarse compound-3 1/2 % pigment, medium compound-4 3/4 % pigment, fine compound-6% pigment.  Corresponding figures for aluminium or "silver" effects are:-coarsest compound-0,75% pigment, medium-1% pigment and fine-1 1/2 % pigment.  In the example the resinous medium consists of 40% coumarone resin, 40% isomerized rubber resin and 20% carnauba wax and is in the form of granules between 80 and 150 mesh British Standard Screen.  The granules are mixed with the metallic pigment for not less than three hours, and the mixture then heated to 65 DEG C. \sB 1 DEG .  The heat treatment is continued for not less than 12 hours or more than 36 hours.  If desired the resin powder may also be heat treated to improve its particle shape and promote better flow during fusion, before it is mixed with the metal pigment.

Abstract: 1,115,850. Reactors. ATOMIC ENERGY OF CANADA Ltd. 1 May, 1967 [26 Aug., 1966], No. 19897/67. Heading G6C. The quality (i.e. the weight per cent of vapour in a mixture of liquid and vapour) of the coolant leaving a reactor core, the coolant being a material which undergoes delayed production of γ-radiation upon subjection to neutron bombardment, is measured by locating a detector producing signals dependent upon γ-radiation intensity adjacent a coolant channel at a point at which the coolant has passed through the core, the signals from the detector being a measure of the coolant density at this point. When the coolant is oxygen-containing, e.g. ordinary or heavy water or organic liquid, the detector is sensitive to y-radiation of about 6 Mev. energy which is produced by decay of N<SP>16</SP>. The signals from the detector are fed along with signals representing the rate of flow of coolant in the channel, the temperature of the coolant entering the channel, the geometry of the reactor and the core flux shape into a computer to calculate the quality of the coolant.
