Title: Material flowrate monitoring system
IPC: B01D53/44
Filed: 1973-02-07
Abstract: 1455021 Mass flowmeter using volume flow and concentration CROFTSHAW (ENGS) Ltd 14 Jan 1974 [7 Feb 1973] 5983/73 Headings G1A and G1N A system for monitoring the rate of flow of material in a fluid comprises means for measuring the rate of flow of the fluid past a fixed point and means for measuring material concentration at a fixed point and means for providing outputs proportional to both of these, a device for multiplying together the signals therefrom, feeding a voltage-tofrequency converter giving a pulsed constant amplitude signal of frequency proportional to the mass flow-rate. The signals are fed to the multiplying device, through noise filtering buffer amplifiers. The pulses are fed to a counter. After the monitoring system, solvent-laden gas passes through two charcoal bed absorbers alternately fed with steam, which removes solvent from the bed. At a predetermined count, the counter sends out a triggering signal to change over the beds or operate an alarm, and resets to zero. Flow measurement (GIN). The system monitors the absorber inlet pipe by a Pitot-Venturi flow element, Fig. 3, with concentric Venturis 22, 23 with trailing end 24 and throat 25 in the same vertical plane and with total head tapping 30 opposing the flow direction, and low and high-pressure outputs 28, 31 connected to a differential pressure transmitter Fig. 4, with chamber 32 bisected by diaphragm 33 causing control 38 to vary an air-flow providing an output pressure proportional to the diaphragms differential pressure to the square root extractor, Fig. 5, the output of which feeds cylinder 52 of a transducer, Fig. 6, with piston 53 moveable against spring 55, causing flexible strip 56 to rotate shaft 59 and hence spindle 62 of potentiometer 63, which thus gives an electrical output proportional to the rate of flow of gas. Solvent concentration measurement (GIA). Beams of infrared radiation pass via an interrupter alternately through two parallel cells, one a reference with no solvent, the other receiving a stream of solvent-laden gas from a probe in the absorber inlet pipe, and then enter an enclosed gas, which alternately expands and contracts with unequal illumination from the cells, to move a diaphragm altering the capacity of a condenser to give a signal proportional to solvent concentration.

Patent GB-777388-A (GB)
Title: Process for hydroformylation of olefins
IPC: C07C27/22
Filed: 1955-03-02
Abstract: Olefines are subjected to a process of hydroformylation comprising passing a reaction mixture, comprising hydrogen, carbon monoxide and a mixture consisting essentially of olefines having dissolved therein a catalytic metal salt for the hydroformylation of olefines at selected hydroformylation temperatures, maintained within a range of 20 DEG  F., and a selected hydroformylation reaction pressure, through an elongated reaction zone of restricted cross-sectional area and having a high ratio of wall surface to reactor volume and in indirect heat exchange relationship with a heat transfer medium, and recycling to said reaction zone to stabilize the temperature therein from one to ten per cent by weight, based upon the fresh olefine feed, of the hydroformylation reaction product produced therein.  The preferred hydroformylation temperature lies in the range 260 DEG  to 460 DEG  F. and the preferred pressure in the range 1500 to 4500 lbs. per square inch.  The hydrogen to carbon monoxide ratio may vary from 0.5 : 1 to 8 : 1.  Preferably, the olefines contain at least 4 carbon atoms.  Suitable olefines are, for example, hexenes, heptenes, octenes, tri-isobutylenes and tetraisobutylenes or mixtures of these. It is preferred to employ as a catalyst a salt of a catalytic metal, for example, iron or cobalt, which is soluble in the olefine charge. Suitable catalysts are, for example, cobalt naphthenate and the cobalt salts of 2-ethyl hexanoic acid, lauric, palmitic and stearic acids.  The ratio of length of reactor to its diameter is preferably at least 1440.  In an example, heptene is treated with a mixture of hydrogen and carbon monoxide in the presence of cobalt 2-ethyl hexanoate as catalyst; between one and ten per cent by weight, based upon the heptene feed, of the hydroformylation product is recycled; the aldehydes produced are hydrogenated to form alcohols.

Abstract: 726,913. Semi-circular devices. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 26, 1952 [March 10, 1952], No. 6213/52. Class 37. The manufacture of a semi-conductor amplifier comprises the steps of forming a P-N junction in a germanium body, which is then annealed and electrolytically etched to render the junction visible. The P-N junction may be produced by heat treatment of N-type germanium, or by fusing together separate pieces of N and P-type germanium. A piece of N-type material 1 is clamped between graphite blocks 2 so that it engages the surface of a piece of P-type material 3 which is placed on a graphite heating element 4. The arrangement is placed in an evacuated chamber and current passed through element 4 so that piece 3 fuses on to piece 1. The specimen is then ground and acid etched, sealed in a tube and given annealing treatment for about 72 hours at 480  C. in vacuo. The P-N junction element is anodically etched in a decinormal caustic potash solution with a platinum counter-electrode. The P-type material etches faster than the N-type so that a rectangular block becomes as shown in Fig. 4, whereby a shoulder is formed which discloses the position of the P-N junction. Fig. 6 shows a transistor in which the P-N block, SC, as described above, is mounted on a brass base 7, and a collector electrode is connected to the P-type portion. One or more emitter electrodes may be provided by point or line contacts which engage the shoulder formed at the P-N junction. The assembly is protected by an insulating cap 12 which may be filled with silicone grease.
