Title: Polyvinyl acetal resins
IPC: D06M15/347
Filed: 1937-04-09
Abstract: Polyvinyl acetal resins containing substantially only acetal and hydroxy groups are prepared by reacting polyvinyl alcohol, derived from a polyvinyl ester having an average macromolecular weight of at least 7000, with a saturated aliphatic aldehyde containing 3 to 5 carbon atoms in solution in the presence of an inorganic acidic catalyst, the reaction being continued until there is produced a resin about 39 to 88 per cent acetalized, and the kind of aldehyde and the degree of acetalization being so correlated that the resin is water-insoluble and substantially insoluble in ester plasticizers at ordinary temperatures, but capable of absorbing large quantities of ester plasticizers to form homogeneous, extensible, resilient compositions of high ultimate strength.  The resins are preferably prepared by adding mineral, e.g. hydrochloric, acid to an aqueous solution of polyvinyl alcohol, then adding, simultaneously and with stirring, aldehyde and a water-miscible solvent for the acetal resin, so that no precipitation occurs.  The polyvinyl ester preferably has an average macromolecular weight of at least 15,000, preferably in excess of 25,000; the aldehydes are preferably straight-chained, the preferred one being butyraldehyde; more than one aldehyde may be employed.  The desirable range of acetalization is 52 to 88 per cent, preferably 62 to 88 per cent, for propionaldehyde, 42 to 82 per cent, preferably 54 to 78 per cent, for butyraldehyde, and 39 to 62 per cent, preferably 41 to 58 per cent, for valeraldehyde. The resins are soluble in water-soluble liquids, e.g. lower alcohols, glycol monoalkyl ethers, (except that valeraldehyde acetals are insoluble in methanol and ethanol) and highly acetalized resins may be soluble in chlorinated hydrocarbons and in ketones.  The ester plasticizer used may be triethyleneglycol di-(2-ethyl butyrate).  The resins may be used in making safety glass or fabric-coating materials.

Title: Improvements in and relating to luminescent materials for use in electric lamps and the like
IPC: C09K11/59
Filed: 1937-04-09
Abstract: 482,071. Luminescent materials. BRITISH THOMSON-HOUSTON CO., Ltd. April 9, 1937, No. 10204. Convention date, April 9, 1936. Drawings to Specification. [Class 98 (i)] In a method of producing a luminescent material consisting principally of cadmium oxide and silica in the proportions corresponding to CdO.2SiO2, impurities consisting of nickel, lead, copper, cobalt and iron, are made non- detrimental or removed by causing a flux containing potassium to react with the metal impurities, part of the flux being utilized in the formation of the material. Cadmium oxide and silica in proportions À8ŒÀ1 : 1 by weight are intimately mixed in a ball mill, and potassium carbonate solution and manganese chloride are added. The ratios of potassium and manganese to the cadmium oxide are respectively 2À1 per cent and 1À25 per cent. The mixture is dried, stirred and heated in air to 1100‹ C. for five minutes or until fuming stops. The impurities are thereby converted to chlorides and are volatized. The major proportion of the potassium chloride acts as a flux for the solid solution of cadmium oxide, silicon oxide and manganese compounds. The resulting fritted mass is pulverized, reheated for several minutes to 1050‹ C., which is just below the temperature at which the crystals sinter together, and then cooled. For maximum brightness, the total percentage of manganese dioxide and potassium chloride is given as 3À1 per cent. The critical ratio of potassium chloride to manganese dioxide is 2. The luminescent material may be applied to a lamp having a plurality of either anodes or cathodes, and containing a mixture of argon and mercury. This mixture gives a radiation 2537A, which combines with the luminescence to give a resultant daylight illumination. Specifications 377,573, 441,603, [both in Group XXIII], and 466,503 are referred to.

Title: Improvements in or relating to electrical devices for measuring small intervals of time
IPC: G04F10/10
Filed: 1947-04-18
Abstract: 654,649. Duration meters. HITCHCOX, G. I. April 18, 1947, No. 10380. [Class 37] [Also in Group XXXVIII] In apparatus for measuring small intervals of time consisting of means for measuring the potential of a condenser C which is charged by a known current during the said interval of time, leakage current in the condenser circuit due to the leakage resistance R1 of the trigger device T is neutralized by the addition of an appropriate current in the opposite direction from an auxiliary supply E2. A balancing resistance R2 is placed in the auxiliary supply circuit, and the condition for no current flow into the condenser from either source is R1/R2=E1/E2, where E1 is the main supply source. The value of E2 is made slightly larger than this to allow for variations in R1. A diode D is placed in the path of the condenser to prevent dissipation of the accumulated potential during charge through the auxiliary circuit when the trigger circuit is re-opened. The charging current is preferably kept constant. Specification 654,675 is referred to.
