Abstract: 1,131,064. Thermistors. VICTORY ENG. CORP. 30 Nov., 1965 [10 Feb., 1965], No. 50824/65. Heading H1K. Metal oxide thermistors are made by forming a dispersion of particles of metal oxide or metal oxide forming materials, having three distinct size-range fractions the largest of which has an average particle diameter not exceeding 1À5 microns, in a solution of a binder vehicle comprising a polymer having an hydroxyl content. The dispersion is deposited on a flat surface, levelled with a doctor blade and dried, and is then fired to sinter the oxide. The coherent flake so formed may then be cleaned by ultrasonic means, and may have electrodes applied to opposite faces, e.g. by vacuum evaporation of aluminium, gold, silver, platinum or other metals or alloys. In the preferred embodiment the metal oxide particles comprise a ground mixture of manganese oxide, nickel oxide and cobalt oxide, the three size fractions having average diameters of not more than 1À5 microns, 1À0 microns and 0À5 microns respectively and being present in equal amounts by weight. The binder vehicle preferably consists of volatile and non- volatile components. The non-volatile component comprises a polyvinyl butyral resin having a chain length of not more than 500 Š, an hydroxyl content of the order of 20% by weight and an acetate content of the order of 2À5% by weight, and a polyvinyl alcohol polymer also having a chain length not exceeding 500 Š. The volatile component preferably comprises a mixture of methyl alcohol, amyl acetate and toluol. After formation and levelling of the dispersion on an optical flat a suitably shaped blank may be cut and dried with absorbent paper. The blank is then covered by a refractory powder and fired. Alternatively the blank may be laid on a substrate of ceramic, metal or silicon, and cemented thereto by application of a solvent prior to firing.

Title: Sustained release pesticide and process of making the same
IPC: A01N25/10
Filed: 1967-11-09
Abstract: 1,212,842. Lignins. WEYERHAEUSER CO 9 Nov., 1967 [14 Nov., 1966], No. 51093/67. Heading C2C. [Also in Divisions A5 and C3] A substantially water insoluble polymeric compound (other than an organotin derivative of a natural polymer) comprises a pesticide moiety hydrolysably attached to a polymeric substrate so that free pesticide is releasable on hydrolysis of the polymeric compound, said polymeric substrate being a natural polymer or a derivative thereof, e.g. bark, comminuted wood, cellulose, kraft lignins, sulphite lignins, soda lignins, caustic extract of bark, tannins, corn cobs, oat hulls, bran, bagasse, fish meal, soybean flour or mixtures thereof. The polymeric compound may be obtained by forming a hydrolysable bond between a pesticide and a polymeric substrate either directly or through the medium of a polyfunctional compound capable of combining with the pesticide to form a hydrolysable bond and with the polymeric substrate, the process being effected under reaction conditions at which no degradation of pesticide occurs, the chemical bond between the pesticide and the polymeric substrate or the polyfunctional compound being more susceptible to hydrolytic cleavage than other chemical bonds in the pesticide. The hydrolysable bonds may be via the oxygen, nitrogen or sulphur of hydroxyl, sulphydryl, amino, imino, carboxyl, amido, imido, sulphonamido, sulphonimido, phosphoroamido, phosphoroimido, thiophosphoroamido, or thiophosphoroimido groups in the pesticides. The examples describe reactions wherein pesticides are first converted to acid chlorides, and reactions involving polymeric substrate/pesticide products linked via toluene diisocyanate or pyromellitic dianhydride. A long list of pesticides is given, those used in the examples being 2,4,5-T, naphthalene -1-acetic acid, 2,4-D, trichloroacetic acid, 2,2-dichloropropionic acid, 4 - amino - 3,5, - 6 - trichloropicolinic acid, 3- amino - 1,2,4 - triazole and 0,0- di - Me S - (N- methylcarbamoyl) methyl phosphorodithioate.

Abstract: 1451028 Making Cr-steels USS ENGS & CONSULTANTS Inc 27 Nov 1974 [28 Nov 1973] 51433/74 Heading C7D Cr-steel is produced by charging molten iron and up to 35% steel scap to a furnace, adding a basic slag-former (e.g. lime), blowing with 02 to reduce the P content to <0À03%, removing the slag formed, adding the desired amount of Cr-bearing material (preferably scrap and Fe-Cr) to the melt, subjecting the melt to a second blow in a bottom blown converter where O 2  is injected surrounded by a hydrocarbon protective (e.g. natural gas, propane) adding a basic slag former and continuing blowing until the desired C-content is reached, purging the furnace with an inert gas (e.g. Ar), adding Fe-Si to reduce oxidized Cr from the slag, and tapping the Cr-steel. The two blowing steps preferably occur in the same bottom blown converter although the first blow may occur in a basic oxygen furnace or a lance-blown open hearth or electric furnace) the O 2  in the first step also being jacketed by a hydrocarbon gas, although Ar may be used if required. The slag removal may be effected by tilting the furnace, using rakes, flushing with gas, or by tapping into a ladle, separating and returning to the furnace. The line is preferably added entrained in one of the injected gases, but in the second stage it may be added in bulk form. Some Ar may be used in the second blow in addition to the O 2  and hydrocarbon, or the melt may be subjected to a partial vacuum, both of which result in less oxidation of the Cr. Examples are given of the production of various grades of stainless steel.

Filed: 1969-10-22
Abstract: 1,267,435. Automatic control of air conditioning. INSTITUT FUR REGELUNGSTECHNIK. Oct.22, 1969, No. 51683/69. Heading G3R. The temperature, humidity and concentration of contamination by harmful water-soluble gases in a test chamber are detected and corrected by an automatic electrical control system to maintain constant conditions in the chamber. As described, an aluminium test chamber is heated by air passing through another chamber containing a cooler and heaters under the control of a three step regulator responsive to temperature within the test chamber. Fans circulate air in both chambers. Humidity is controlled by an on/off regulator, responsive to humidity in the test chamber, which controls, through a relay, the heater of a vaporizer supplying water vapour to the test chamber. Humidity detection is by variation of electrical resistance due to variation of thermal conductivity with change of humidity in a cell maintained at constant temperature within the test chamber. The concentration of contaminating gas is controlled by a five-step regulator, responsive to a conductivity measuring device within the test chamber, which controls the number of parallel restriction paths to the chamber from a thermostatically-controlled liquid gas container supplying contaminating watersoluble gas.
