Title: Improvements in or relating to grinding machines
IPC: B24B5/22
Filed: 1920-07-09
Abstract: 147,840. Norma Cie Ges., and Schweickardt, B. March 1, 1918, [Convention date]. Rollers, spindles, rods, and the like, treating.- A machine for grinding cylindrical bodies comprises a grinding-wheel b1, b2, against the periphery of which the bodies d are pressed and rotated, and across which they are fed by means of a rotating disk c. The bodies are supported in a guide a, and the axis of the disk c is placed so as not to intersect the axis of the bodies; this disposition of the parts causes a rotation and axial feed of the bodies. The grinding-wheel may comprise two disks b1, b2 of different grain, whereby the bodies may be ground and polished at a single operation. Rotary driving-plates may be provided to receive and rotate the articles undergoing treatment before entering the grinding-section and after emergence therefrom; long cylinders may then be treated. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of a cupshaped grinding-wheel engaging the work on one side of its axis only when treating long bodies, or engaging the work on both sides of its axis when treating short bodies. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the preparation of melamine
Filed: 1944-10-16
Abstract: Melamine is prepared by heating one or more of the compounds urea, ammonium cyanate, biuret, cyanuric acid, ammelide, ammeline and guanyl urea, to a temperature of at least 270 DEG  C., and preferably at least 300 DEG  C., in the presence of ammonia.  At least part of the ammonia present may be that resulting from thermal decomposition of the starting material, for example, the starting material may be heated in a closed autoclave with or without the addition of ammonia and under a pressure of at least 100 lbs. per square inch.  The pressure may be that autogenously developed on heating in a confined zone.  If the materials are heated to at least 350 DEG  C. and a part of the zone is kept at a temperature below 350 DEG , sublimed melamine collects in the cooler zone.  A cyclic process is described in which the melamine is separated from the carbon dioxide and ammonia which are formed in the reaction, and the latter are combined in known manner to form urea which is returned to the process.

Title: Improvements in drop down guns
IPC: F41A19/54
Filed: 1919-08-16
Abstract: 150,522. Britte, L., and Britte, T. Aug. 16, 1919. Breech actions, drop-down barrel.-Relates to drop-down guns in which, on closing the barrels, a piece pivoted on the body is adapted to cause compression of the cocking spring, the movement of the piece being transmitted to the spring at a point behind the pivot of the body near the hammer. According to the invention, the transmission is effected by one or more levers each pivoted approximately at its centre in the body, and the pressure is exerted downwardly on one arm of the spring at a point near the end of the arm. In the form shown in Fig. 1, closing the barrels 9 rotates the piece 10 pivoted on the hinge 12 and through levers 14, 16 depresses the arm 4 of the cocking-spring. The other arm 1 presses on a link 2 depending from the hammer 3, so that when this is released by tripping the sear 7, the hammer is impelled forwards to fire the cartridge. On opening the barrels, the arm 4 of the spring, by reason of its greater leverage, rotates the hammer into bent. Modifications are described in which the levers 14, 16 are replaced by a single lever.

Title: An improved method of and apparatus for heat-treating materials
IPC: C22B4/00
Filed: 1926-04-16
Abstract: 266,402. Prentice, J., and Pehrson, A. P. April 16, 1926. Electrode and resistance furnaces.-In the heat treatment of solid materials in a rotary or oscillatory electrically heated furnace having openings for the continuous admission and discharge of the material, the latter is maintained at the same level throughout the furnace as that of said openings which are in the form of necks at opposite ends of the furnace. When distilling coal or material normally a non-conductor, the temperature is raised to that at which the charge becomes a conductor and this may be done by first adding a conducting material such as coke, carborundum, semi-coke or calcined anthracite and then passing a current until a temperature of about 500‹ C. is attained. The charge may be preheated by introducing it through hollow contact plates into the furnace. When heating iron oxide chrome ore or barium oxide a resistor of greater density than the product may be used and may be allowed to remain permanently in the furnace, a perforated plate or grid retaining the resistor. The chamber A of a rotary furnace has contact plates B connected to slip rings C and communicates with a preheating chamber K and a cooling device L for the residues. The material from a hopper M is fed through the preheater by a screw conveyor k and after treatment in the furnace passes through a spirally arranged pipe L dipping into a cooling liquid in a trough l. Gas outlets P, P<1> are provided, and a steam outlet k<1> from the externally-heated chamber K. By varying the cross-sectional area of the furnace variations in temperature of the material treated are obtained. The preheating chamber may be dispensed with.
