Title: Process for the agglomeration of pulverulent metalliferous materials
IPC: B01J2/22
Filed: 1960-02-11
Abstract: An agglomeration process for highly pulverulent metalliferous materials, especially for subsequent reduction and smelting in a shaft furnace, consists of subjecting the materials to a progressive controlled crushing operation with re-cycling of the oversize on a mesh size between 0.5 and 5 mm. to obtain a product having a constant size distribution, preparing by similar means using a mesh size between 1 and 3 mm. a crushed solid reducing agent such as coke or coal, mixing the reducing agent with the crushed metalliferous product to form a mixture containing 2 to 12% by weight of the reducing agent, adding water to bring the moisture content of the mixture to between 7 and 16% and compressing it under at least 250 Kg/cm.2 in order to produce ovoids having volumes of 20 to 40 c.c. The mesh sizes and the crushing powers of the crushers are selected in such a manner to give the above proportioned mixture a constant size distribution whose diagram is a curve with positive gradient similar to an inclined reversed elongated "S." 1 to 3% by weight of lime or acid powder may be added to the mixture to correct any excess acidity or basicity.  The process may be combined with a known sintering process, wherein the raw materials are subjected to a dust-removing operation, the fine dusts being mixed with any fine sintered products which have been already subjected to decomposition prior to screening and progressive controlled crushing with recycling, and only the dust-free product is subjected to a sintering process prior to screening, the screenings of the latter being mixed with the above fine sintered dusts.

Title: Improvements in and relating to the manufacture of tablets having a gelatinous base
IPC: A61K31/43
Filed: 1947-02-20
Abstract: Tablets having a gelatinous base, containing up to 25 per cent medicament, antibiotic or food accessory are formed by conditioning gelatine particles to a suitable moisture content, adding the medicament and compressing to tablet form.  The tablets are then case hardened by dipping or spraying with water or water containing organic solvent, and drying at an elevated temperature, e.g., in hot air, so that the surface of the tablet melts and forms a hard coating.  The tablets may then be further dried to reduce the moisture content below 8 per cent.  The use of such tablets as a medium for administering penicillin is mentioned.

Abstract: 851,056. Automatic temperature control systems. DAYSTROM Inc. Feb. 18, 1957 [April 19, 1956], No. 5420/57. Class 38 (4). A temperature control system for heating means comprises a thermocouple and an opposed voltage reference source, their difference error signal operating control means via a D.C. amplifier which has a four-arm R-C bridge in a feedback loop. The thermocouple 2 and voltage reference source 1 are opposed and at the correct furnace temperature there is no output voltage. With change of temperature an error voltage is applied to the D.C. amplifier, whose output operates a switch 5 controlling the furnace heater 4. The amplifier is provided with current negative feedback by resistor 9 common to the input and output circuits. Differential and integral components are produced across resistor 9 by the lattice network 13, 14, 15, 16, the resistor 17 providing a first-order feedback component. Back-to-back rectifiers 18, 19 are Zener diodes which conduct under the voltage conditions existing during warm-up or cooldown periods, but not during operation involving small variations about the control point. The instrument 12 which monitors output current may be calibrated to read temperature deviation. Figs. 1 and 2 (not shown) provide a theoretical build-up of the lattice network shown in Fig. 3.

Overheating of superheating-tubes, preventing. -When the boiler regulator-valve is closed, an auxiliary supply ef steam is admitted to the superheater and the cylinder steam-chest through a differential-piston valve B, which, when the pressure in the superheater reaches a predetermined point, which is considerably below the working pressure of the engine, closes the port G of the auxiliary-supply pipe and opens an escape passage J. When the regulator is open, the steam from the superheater, admitted through the port H, acts upon the large end of the piston valve and closes the port G, and at the same time, the check valve J<1> is pressed upon its seat and closes the escape passage J.
