Title: Apparatus for preparing bamboo and kindred material for pulp extraction
IPC: D21B1/06
Filed: 1928-11-22
Abstract: 323,611. Jardine, J. L., and Nelson, I. T. Nov. 22, 1928. Breaking-apparatus. - Bamboo and like stems are disintegrated by being passed through pairs of rollers which are grooved circumferentially to split the stems along their length, and pairs grooved longitudinally to bend them at right angles thereto. The rollers are graded in depth and pitch to increase the severity of the action. Each roller comprises a core 1, Fig. 1, with a reduced journal portion 2 at each end, a divided two part cover or sleeve 3, and end flanges 4. The sleeves are either grooved circumferentially to form knife edges 7, Fig. 2, or longitudinally to form ridges 10, Fig. 1. The upper and lower rollers of each pair are arranged so that the knife edges or ridges interengage but do not touch. Tables are arranged between the pairs of rollers to convey the material and these tables may be perforated to allow the dust to fall therethrough and be drawn away by a fan.

Title: Improvements in or relating to the production of photographic silver halide emulsions
IPC: G03C1/04
Filed: 1938-12-06
Abstract: 523,661. Photographic silver halide emulsion. CZEIJA, O., and LIERG, F. Dec. 6, 1938, Nos. 35593 and 35594. Convention dates, Dec. 6, 1937 and June 20, 1938. [Class 98 (ii)] In the production of silver halide emulsions, the carrier colloid has added thereto or produced therein colloidal silver halide having a particle charge opposite to the charge of the carrier colloid without completely neutralizing the charge of the carrier colloid. The carrier colloid may be a cellulose derivative or a polymerization or condensation product such as polyvinyl alcohol or polyacrylic acid, or a mixture of one or more of such substances. If the carrier colloid has a negative particle charge, the components for forming the silver halide are so added that there is an excess of the silver compound over the halogen compound at each instant during the formation of the silver halide and the silver compound remains in excess at the completion of the operation. The excess controls the resulting gradation. Conversely, if the carrier colloid has a positive particle charge, the halogen compound is maintained in excess. Part of the silver compound may be replaced by a compound or compounds of another metal or metals, for example thallium, which impart a positive charge to the silver halide. Examples of carrier colloids are partially etherified cellulose or partially saponified cellulose esters. A negative charge may be increased by treatment with alkalis and a positive charge increased by treatment with acids. Suitable solvents in the case of cellulose acetate are methyl and other alcohols, acetone, diacetone alcohol, chlorinated hydrocarbons and mixtures of acetone and water. Positive charges may be reduced by addition of acid dyes or colloidal metals, and negative charges by the addition of basic dyes or colloidal oxides or hydroxides. The support may be glass, metal, paper, celluloid or cellulose acetate. No support need be employed. One or more emulsion layers and filter or other intermediate layers may be provided. A small amount of high-boiling solvent, for example, diacetone alcohol, may be added to promote adhesion of the emulsion to the supporting layer. The emulsion may be used for sound recording and may be colour sensitized. In an example, cellulose acetate is partially saponified with alkali and the emulsion either prepared directly from the saponification solution or after washing and re-solution.

Title: Method and means for the transmission of heat

Filed: 1946-12-03
Abstract: 629,298. Heating gases, feedwater heating systems. DALIN, D., and HAGBY, G. V. Dec. 3, 1946, Nos. 35787 and 35788. Convention dates, Dec. 7, 1945, and Jan. 21, 1946. [Classes 64(i) and 64(iii)] A system for transferring heat from hot gases, such as flue gas, to cold gas, such as the air supply to a boiler, employs a circulating liquid flowing through two heat-exchangers 1 and 4, heat being imparted in the first heat exchanger by the hot gas to the liquid and in the second by liquid to the cold gas, and the system is characterized in that the temperature of the liquid on entering the first heat exchanger is maintained above the dewpoint of the hot gas, thus obviating precipitation. In its simplest form, Fig. 1, the system comprises the first heat-exchanger 1, in which the liquid, flowing through pipes 1a, receives heat from flue gases passing around the pipes. The liquid, after passing through an expansion vessel 2, is driven by a pump 3 through looped pipes 4c in the heat exchanger 4, a portion of the liquid being diverted through a by-pass 5. The flow through the by-pass is controlled by a thermostat 5a connected to the' heat exchanger 1, so that the resultant temperature of the liquid entering the heat exchanger 1 exceeds the dewpoint of the flue gas (generally approximately 60‹C.), thus obviating objectionable precipitation of moisture and sulphur compounds. As shown in Fig. 8, the system may be extended to heating the feedwater to a boiler 28, a heat-exchanger 33, in parallel with the heat exchanger 4, being employed for the purpose. In order to reduce the temperature of the circulating water, the feedwater is first cooled by passing through the coils 46 in the heat-exchanger 4. The cooled circulation water from the heat exchanger 33 is then returned to the cold end 6 of the heat exchanger 1, but the warmer water from the heat exchanger 4 is returned by a pipe 43 to a tapping 45 on the heat exchanger 1, where the liquid is approximately at the same temperature.
