Abstract: 1,190,130. Explosive compositions. HERCULES Inc. 30 Dec., 1968 [29 Dec., 1967], No. 61766/68. Heading C1D. A non-aqueous blasting composition, from which a nitrated polyol is substantially absent, contains an inorganic oxidizing salt and, as an energizer, 2-18% of silicon and/or a silicon alloy containing at least 70% silicon, the silicon component substantially all passing a 30 mesh U.S. standard sieve. Suitable oxidizing salts are ammonium, sodium, magnesium, calcium, potassium, and barium nitrates and sodium, calcium, magnesium, and ammonium perchlorates. The composition may be of the ANFO or NCN type and include 1-8% of a supplemental fuel, e.g. particulate Al, sulphur, gilsonite, finely-divided coal, mono- and dinitrotoluene, ethylene glycol, granulated sugar, paraffin wax, nitroparaffins, and hydrocarbon fuel oils.

Patent GB-636652-A (GB)
Abstract: 636,652. Closed stoves. SPLADIS SOC. POUR L'APPLICATION D'INVENTIONS SCIENTIFIQUES. Dec. 31, 1947, No. 35128. Convention date, April 27, 1946. [Class 126] [Also in Group XIII] Forced draught apparatus for the combustion of solid fuel at its undersurface is provided immediately below the firebox, with a heat-insulated combustion chamber from which combustion gases pass to a condensation receptacle by way of ascending and descending tubes. Cylindrical fuel blocks 11 contained in a fuel store 1 are burnt at the lower end only in a firebox formed from a double conical member 9 provided with radial ribs 10 which support the fuel. Forced draught from an inlet 4 passes between the fuel holder 1 and a surrounding casing 2 to the firebox. Combustion gases pass from the firebox into a combustion chamber 15, where ash may also be collected, and thence to radiating tubes 18 fitted with internal baffles 19. A collector 23 having a detachable cover 24 connects the ascending tubes 18 to descending tubes 27 also fitted with internal baffles. Before reaching the chimney, gases leaving the descending tubes 27 pass into a condensation receptacle 28 provided with a drain cock 30. Semicircular metallic baffle plates 19 engaging in transverse slots 20 in vertical sheet metal strips 21 are suspended in the tubes 18, 27 by transverse projections 22 resting on the bottom 23<SP>1</SP> of the collector 23.

IPC: C07C11/02
Abstract: 664,359. Cracking hydrocarbons to make olefines. KAFTAL, G., and BALLABIO, G. May 18, 1948 [May 30, 1947], No. 13481/48. Class 32 Olefines of low molecular weight are obtained from mineral oils, mineral oil distillates (petrol, kerosene, gas oil), coal tar oils and pitch, by atomizing the raw material in intimate admixture with air or oxygen into a heated chamber, the amount of oxygen being sufficient, by combustion of part of the raw material, to maintain the chamber at a temperature greater than 480‹C. The reaction may be carried out in the presence of steam ; and a catalyst such as pulverized silica gel, may be employed. Chamber A which is lined with refractory material, was preheated to 600‹C. by means of burner M. The combustion gases leave through chimney L. A fuel oil (Engler viscosity 6 at 60‹C.) was then sprayed with oxygen (containing nitrogen as impurity) through sprayer I; burner M was turned down, chimney L was closed and outlet O was opened. The proportion of oxygen to oil was adjusted so as to maintain the chamber at 620‹C. Coke (6 per cent by weight of the feed-oil) was discharged from the bottom of the chamber. The vapours leaving through outlet O were passed through dustremover B, and then cooled in heat-exchanger C which is also used to preheat the feed-oil and oxygen. The vapours were then passed through cooler D where a liquid condensed, and the olefine-rich gas remaining was then washed free from carbon dioxide in scrubber N. The condensate was divided into two aromatic fractions with a cut-point at 180‹C. The olefine-rich gas, which comprised 58 per cent by weight of the feedoil, contained ethylene (28 per cent), propylene (10 per cent) and butylene (5 per cent). The saturated hydrocarbons separated from the gas, and the higher-boiling liquid fraction, may be returned to the reaccolumn 3.

Title: Compensating for fluid channel dimension variations in a flowmeter
IPC: A61M1/16
Filed: 1978-07-31
Abstract: A flowmeter for measuring small differential fluid flow rates, of dialysate input to and output from a dialyser, comprises two similar, rectangular section channels 11, 12 and a compensating or calibrating circuit eliminating the effects of variations in the channel heights or "diameters". The channels are in a magnetic field H, so that the flow of dialysate generates an e.m.f. between electrodes 13 and 14 in the channels, which is representative of the differential flow rate. The compensating for channel height mismatch is effected by using a signal proportional to common mode flow rate from electrodes 15 and 16, which is amplified by a factor whose ratio to the differential flow rate signal amplification factor is proportional to channel height mismatch, and summing the two amplified signals. The common mode flow rate amplification factor is determinable by a calibration procedure. A suitable circuit is disclosed (Figs 6 and 7 not shown). <IMAGE>
