Title: Improvements in and relating to resinous compositions and methods of making the same
IPC: C08G8/28
Filed: 1934-01-23
Abstract: Resins are prepared by heating phenol with a molecular excess of formaldehyde in the presence of 5 to 100 parts of A-stage alkyd resin per 100 parts of phenol at a temperature not exceeding 130 DEG  C. In examples, a mixture of phenol and A-stage alkyd resin is heated with paraform with or without the addition, just before the completion of the heating, of dyes or pigments, to yield a resin. The alkyd resin is derived from (1) glycerine and phthalic anhydride, and (2) glycerine, phthalic anhydride, glycol and adipic acid or succinic acid.  The resins, which are normally fluid, may be used as impregnating agents without solvents for paper in the manufacture of coils and in the manufacture of rods, sheets, tubes, radio knobs, umbrella handles, pen holders, cigar and cigarette holders, door knobs, inkwells and lenses.  The resins may also be used as varnishes dissolved in solvents such as acetone, alcohol and benzene. Specification 376,929 is referred to.

Title: Improvements in method of preparing transparent luminescent screens
IPC: H01J9/22
Filed: 1958-01-27
Abstract: 820,777. Luminescent screens. GENERAL ELECTRIC CO. Jan. 27, 1958 [Feb. 25, 1957], No. 2642/58. Drawings to Specification. Class 39(1). A method of preparing a transparent luminescent screen comprises evaporating a crystalline layer of phosphor host material onto a transparent substrate in a vacuum, after which an amorphous layer of the phosphor host material and primary activator is evaporated on to the crystalline layer and finally the coated substrate is heated in an atmosphere of a reducing gas and an activating gas so that the amorphous layer is activated and crystallizes. The first crystalline layer provides a good bonding surface and need not be activated, the evaporation on to the substrate being carried out with the receiving surface at between 100 and 650‹C. and preferably at 125‹-200‹C. until a thickness of about 0À25Á is obtained. The substrate is then cooled to between 0 and 100‹C. and preferably to between 25‹C. and 80‹C. when an amorphous layer of phosphor is obtained by further evaporation owing to the lower temperature. The activator may be included in the layer by evaporating previously activated phosphor or a mixture of phosphor and activator, or alternatively by evaporating the activator from a separate container either at the same time as or subsequent to the evaporation of the phosphor host material. The phosphor material may be of the group comprising zinc, cadmium, sulphide and selenide and the primary activator may be silver, copper, arsenic or phosphorous. The co-activator is preferably a halogen so that the activating gas in the final stage of preparation is for example hydrogen chloride and in order to prevent excess evaporation of the phosphor during heat treatment, the reducing gas has the same anion as the phosphor material, for example hydrogen sulphide may be used with zinc sulphide phosphor. During heat treatment chlorine atoms freely penetrate the amorphous phosphor layer and become associated with the primary activator, the activated phosphor finally becoming crystalline as its temperature is raised. In this final stage the substrate may be heated to 500-750‹C. Detailed examples are given.

Abstract: 139,271. Greten, C. A., and Musman, F. Feb. 3, 1919. Valves.-In an engine with a single sleeve valve reciprocating between tEe piston and the cylinder, three rings of ports, viz. ports 4 for exhaust and 5, 6 for admission, are provided in the sleeve co-operating with exhaust ports 7 and inlet ports 8, 9 in the cylinder. The operation is as follows. The exhaust ports 7 are opened at end of power stroke, and compressed air for scavenging is admitted through ports 9 and expelled through the ports 7 during the exhaust stroke; on the next stroke, air is first drawn in from the exhaust pipe through the ports 7, then the ports are closed, a partial vacuum is formed in the cylinder, and, later, hydrocarbon gas or vapour from the vaporizer is admitted through ports 8, and finally an additional charge of compressed air through ports 9. The charge is then compressed and fired in the usual manner. The sleeve valve moves in the same direction as the piston during the power stroke.

Title: Improvements in or relating to the production of itaconic acid
IPC: C12P7/44
Filed: 1956-01-31
Abstract: Itaconic acid is produced by the fermentation of an aqueous sugar-containing nutrient medium by the aerobic cultivation therein of eumycetes, such as species of the genus Aspergillus, which will convert sugar into itaconic acid, characterized in that the nutrient medium contains one or more finely divided adsorbents.  Suitable such adsorbents are anhydrous calcium sulphate, kaolin, bleaching earth, fuller's earth or anhydrous silicic acid, used singly or in admixture.  The adsorbents may be activated in known manner, an example being the heat activation of gypsum.  With an average particle size within the range of 1 to 50m , a suitable concentration of adsorbent is 0.5 to 5 grams per litre of nutrient medium.  In examples, a nutrient medium comprising sucrose, ammonium sulphate, magnesium sulphate, monobasic potassium sulphate in tap water with (1) heat-activated calcium sulphate, (2) kaolin, or (3) fuller's earth as the adsorbent, is sterilized and then inoculated with Aspergillus terreus at 32 DEG  C. under atmospheric pressure with careful temperature control, stirring and aeration, whereby itaconic acid is produced.  A comparative example using the same nutrient medium but with the omission of the adsorbent gives lower yields of itaconic acid.  Specification 602,866 is referred to.
