Title: Process for the manufacture of glues, gelatines and the like from plagiostomaceous materials
IPC: C09H3/00
Filed: 1926-11-04
Abstract: 267,041. Ehrenreich, A. July 12, 1926, [Convention date]. Gelatine; glue. - The invention comprises a process of extracting glues, gelatines &c. from skins, pectoral and other fins and all gelatinous waste of plagiostomi such as sharks. The raw material, freed from soluble impurities by washing in water, is treated with water in a dissolving vat preferably of wood or cement and provided with a perforated partition, as a grid of wood laths or galvanized wire cloth, and a steam heating coil. The liquid is heated to 70-80‹ C., the steam is shut off for a few minutes and then turned on again until bubbling occurs in the vicinity of the coil, when' it is finally shut off. The liquid is allowed to stand until of the desired consistency and impurities which rise or settle are removed. The viscous liquid remaining is variously treated to obtain solid or liquid glue or gelatin. To obtain solid glue it is either treated in a refrigerator or, after adding a hot solution of boric acid, is transferred to sealed boxes with movable sides. After standing for 2-3 days the box-sides are removed and the solid glue is cut into thin slices which are placed on a grid to dry at a temperature of 35-40‹ C., air and light being excluded. To obtain liquid glue, the liquid is heated to evaporate the solution to the desired consistency, and filtered through cloth'into another vat where it is cooled to about 40‹ C. Hydrochloric or acetic acid and preferably oil of sassafras is added and the product placed in tins, bottles &c. To obtain pure gelatine, the raw material is specially purified, by removal of all foreign materials, followed by treatment with lime for 1-2 weeks, washing in water, and bleaching with sulphurous acid or hyposulphite and hydrochloric acid. The remaining treatment is as described for solid glue, except that no preservative is added, and the product is poured into smooth flat boxes to form thin sheets.

Abstract: 906,378. Coin-freed apparatus. ICE-MATIC Ltd. Oct. 17, 1960 [Aug. 16, 1960], No. 28375/60. Class 27. A coin-slot plate-control for an automatic vending machine comprises a solenoid-operated pawl 13 which is operated at each rotation of a magazine containing a plurality of stacks of packages for sale and moves a ratchet-wheel 12 stepwise to a position wherein a cam-plate 32 fixed to the ratchet-wheel permits an arm 43 carrying the coin-slot plate 37 to move the plate from an operative to an inoperative position. The pawl 13 is pivotally mounted on a rod 14 which is movable downwardly against the action of a spring 22 by a solenoid 17 energized by a switch closed once for each rotation of the magazine. The pawl is retained in engagement with the teeth of the ratchet-wheel by a surface 25 engaging an adjustable pin 26 during the downward movement of the pawl. During the return movement of the pawl, the ratchet-wheel is prevented from rotating by a second pawl 28. The cam-plate 32 and a graduated disc 30 are secured to the ratchet-wheel. The graduated disc enables the cam-plate and ratchet-wheel to be set to a position corresponding to the number of packages in a stack in the magazine. The cam-plate has a cut-away portion 33 which, when the disc and ratchet-wheel are in a zero position corresponding to the magazine being empty, receives a pin 44 on the arm 43 and enables a spring 45 to rock the arm about a pivot 36 to move the coin plates 37, 38 from a position wherein slots 39, 40 for receiving sixpences and shillings, respectively, are accessible through openings 41, 42 to a position wherein the slots are displaced from the openings and the word " empty " appears therein.

Title: Boron nitride fiber manufacture
IPC: C01B21/064
Filed: 1966-06-27
Abstract: Fibres incorporating a boron and nitrogen containing compound and having a boron content of about 28 to about 43.6% and a nitrogen content of about 8.5 to about 63%, by weight are formed in situ from a precursor fibre of maximum diameter 30m  which incorporates throughout its thickness a boron and oxygen compound by reacting said precursor fibre with a nitrogen and hydrogen containing compound. Preferably fibres consisting essentially of boron nitride are produced from precursor fibres, of maximum diameter 10m  and containing a boron oxide composition, by reaction with a gaseous nitrogen and hydrogen containing compound e.g. ammonia.  The precursor fibre may be heated to a final temperature above 300 DEG C. at a temperature rise of at least 25 DEG  per hour while simultaneously passing gaseous NH3 at a flow rate of at least about 0.025 litre/min/g. of fibre until the resulting fibre has the required composition. To increase the corrosion resistance of the boron nitride fibres (a) the NH3 flow rate may be reduced to below the final temperature, or (b) the precursor fibre may be rapidly heated to the final temperature and the flow rate then reduced or (c) oxygen and/or water vapour may be added in minor amounts to the ammonia. After nitriding the corrosion resistance may be further improved by heating the resulting fibres in an inert atmosphere to a stabilizing temperature of 1400-2500 DEG  C. for a time of between 5 minutes and 2 hours, the higher the temperature the shorter the time. This step may be preceded by a step of heating the fibres at a lower temperature in an atmosphere containing compound containing oxygen or water vapour.
