Abstract: 827,214. Separating liquid particles from gases. IMPERIAL CHEMICAL INDUSTRIES Ltd. Nov. 25, 1957 [Nov. 28, 1956; Nov. 21, 1957(2)], Nos. 36346/56, 36379/57 and 36380/57. Class 123(3) Mists of particle size less than 5 microns are removed from gases or vapours by passing the gas &c. through a filter composed of fibres of diameters mostly in the range 5 to 50 microns, the fibres being "non-wettable", that is, the mist deposits substantially, completely in the form of discrete droplets held on the surface of but not surrounding the fibres, the spaces between the droplets being substantially free from filmlike deposits as shown in the Figure. Suitable fibres are glass fibres having an adherent silicone surface, the silicone preferably being a product made by the partial hydrolysis and polymerization of a methyl chlorosilane mixture consisting essentially of dimethyldichlorosilane, or garnetted "Terylene" (Registered Trade Mark) polyester fibres. The filters may be made by packing fibres between confining metal gauzes but are preferably preformed into bodies of the desired shape by compressing the fibres which are in some degree thermoplastic in a mould and heating whilst under compression to relieve the stresses in the fibres, the treatment with silicone in the case of glass fibres being applied after the stress relieving operation. The surfaces of such preformed filters may be protected by enclosing the filter in a container of glass cloth. The process is of particular application to the removal of fine sulphuric acid mist from the tail gases of a sulphuric acid plant.

Title: Improvements in the recovery of organic solvents
IPC: C07C17/38
Filed: 1961-10-11
Abstract: 997,968. Solvent recovery by condensation. CELANESE CORPORATION OF AMERICA. Oct. 11, 1961 [Oct. 14, 1960], No. 36460/61. Heading B1B. Organic solvent, entrained in the vapour state in a stream of gaseous medium, is recovered by bringing the stream of gaseous mixture into heat-exchange relationship with a countercurrent flow of a fluid coolant whereby the solvent vapours are condensed while the temperature of the stream of coolant rises above that of the solvent-depleted gaseous medium. The warm coolant is then brought into indirect heat exchange wtih the cooled gaseous medium, so that heat is re-transferred from the coolant to the gas. The coolant is further cooled by refrigeration before being recirculated to the process. The apparatus shown is employed to recover methanol and methylene chloride from an air stream which has been used to evaporate the solvents from freshly-made cellulose acetate tow. The solvent-air mixtures, which also contains water-vapour, is fed at 150F. into chamber 20 where it is cooled to 0 F. by heatexchange with liquid solvent mixture, withdrawn from receptacle 22 at -18 F., passing through coils 21. Some condensation of solvent vapours takes place in chamber 20 ; and the condensate flows into receptacle 22. The solventair mixture enters chamber 23 where it meets sprays 24 of coolant consisting of methanol, methylene chloride and water at -20F. Methanol and methylene chloride vapours are condensed out of the air, and the condensate mixes with the coolant which collects in receptacle 22. The air containing reduced quantities of solvent vapours leaves chamber 23 at a temperature of -4F., and enters chamber 29. The coolant, which leaves coils 21 at a temperature of 130 F., is passed through coils 30 where it gives up heat to the air passing through the chamber 29. The temperature of the coolant leaving coils 30 is thus lowered to 56 F., while the temperature of the air leaving chamber 29 is raised to 110 F. Some of the coolant is continuously removed from tap 31 for solvent recovery, and the remainder is passed to multi-stage refrigerator 25 prior to being recirculated to sprayers 24. The warm air leaving chamber 29 may be passed to an activated-carbon absorption system to remove residual solvent, and then used to evaporate fresh solvent from the cellulose acetate. A process is also described in which the spraying operation is dispensed with; brine, glycol, alcohol or oil may be used at coolant.

Abstract: 1,263,716. Control of A.C. motors. MIDLAND TRANSFORMER CO. Ltd. 16 Oct., 1969 [31 July, 1968], No. 36472/68. Heading H2J. [Also in Division H1] A starter for a single-phase motor 10 comprises an auto transformer 12 whose tap 19 is driven by an auxiliary motor 23 and is adapted to bridge contacts 16, 17, in its final position whereby the whole of the supply voltage is applied to the motor. When the tap reaches its final position, a main switch 21 is shunted, this switch being coupled with a switch 24 in circuit with the auxiliary motor. The motor 23 may be programmed so that the tap pauses at the halfway position, for example. The transformer-coil has a rectangular crosssection and is provided with two axial tracks adapted to be engaged by brass and carbon rollers respectively which are connected in parallel, the track engaged by the brass roller containing contacts flush with insulation. The carbon roller maintains contact between the tap assembly and the coil while the brass roller moves from turn to turn. In another arrangement, the tap assembly has a stepwise movement whereby the carbon roller stays on one turn while the brass roller moves from that turn to the next, the carbon roller then moving on to the said next turn. The rollers are driven by a screw-and-nut device, a threaded shaft being rotated from the auxiliary motor through a Geneva mechanism. A magnet is energized when the switch 24 is closed and an abutment engages a star-wheel so that upward movement of the tap assembly is controlled by the snap mechanism. Quick return movement of the tap assembly takes place when a " stop " button is pressed, the abutment being withdrawn from the star-wheel. The return movement may be effected by a clockwork motor, the motor 23, a further auxiliary motor, or a weight. The rollers may be replaced by brushes.

Title: An alarm system for signalling faults or disturbances in electrical installations
IPC: G08B23/00
Filed: 1956-11-29
Abstract: 838,506. Protective arrangements. HOLUSA, J., STREJCEK, V., VANICEK, A., ZEMAN, J., and VELTECHNA NARODNI PODNIK. Nov. 29, 1956 [Nov. 29, 1955], No. 36525/56. Class 38 (5). In an alarm and fault-indicating arrangement for an electric supply system, the closure of contacts 23 in response to a fault causes the energizing of a relay 2. This relay closes its contacts 9 to connect the coil of a relay 3 to a bus-bar 30. The coils of the relay 3 and a relay 15 are thus connected in series, but only the relay 15 is sufficiently energized to operate and by closing its contacts 17 causes the sounding of an audible alarm 22. The relay 2 also closes contacts 11 to connect an indicating lamp 4 to a bus-bar 31 which is energized by means of a vibrator 20 so that the lamp 4 is caused to flash. The manual operation of a switch 24 causes the short-circuiting of the relay 15 which opens to stop the audible alarm. At the same time the relay 3 becomes fully energized and operates to open contacts 8 and close contacts 6 so as to disconnect the lamp 4 from the bus-bar 31 and connect it directly to the auxiliary supply source 28, so that the lamp 4 now emits a constant light. The relay also closes contacts 5 to complete a holding circuit for itself so long as the fault remains and opens contacts 7 to cause relay 2 to release. Each protected installation would be provided with the components within the rectangle 1, the alarm 22, the relay 15, the vibrator 20, the bus-bars and the auxiliary source being common to the whole system.

Abstract: 1,094,768. Transistor oscillator circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 16, 1966, No. 36536/66. Heading H3T. A crystal controlled oscillator has its frequency stabilized against temperature variations by means of a voltage variable reactance, e.g. a varactor diode D3, whose reactance is controlled by the difference between the outputs of two temperature sensitive networks 1, 2. The network 1, comprising Zener diode D1 and negative temperature coefficient resistor RT, has a cubic law, and the network 2, comprising Zener diode D2 and positive temperature resistor RS, has a linear law. The outputs of the two networks are applied to a differential amplifier, the output from which controls the reactance of the varactor diode D3 in series with the crystal 5. The values of resistors R6, R7 and R4, R5 are adjusted to give correct working at normal temperatures.

Abstract: 349,953. Heat exchangers. KRUPP GERMANIAWERFT AKT.-GES., F., Kiel- Gaarden, Germany. Nov. 29, 1929, No. 36695. Convention date, Dec. 3, 1928. Void [Published under Sect. 91 of the Acts]. [Class 64 (iii).] A plate heat exchanger, more particularly intended for heating furnace air by waste gases, consists of corrugated metal plates the corrugations of adjacent plates making an angle with each other and the heat exchange media passing through alternate spaces between plates. The crests of the corrugations of adjacent plates may be in contact. Waste gases flow up the flue A and air flows at right-angles through the passage B, the corrugations of half the plates being parallel to the direction of flue A and the corrugations of alternate plates being at rightangles. The gases and the air flow through alternate passages produced by the plates and strips K, H, strips K forming with the plates passages for the gases and strips H forming passages for the air. Each of these strips will cut one plate in a direction normal to its corrugations and this edge will be serrated, while the other edge cuts the other plate in a direction parallel to its corrugations and this edge is consequently straight. Thus the strips may be formed by bending over the edge of the plate the corrugations of which are parallel to the strip, and, after serrating this edge, welding it to the edge of the other plate. The apparatus may be made in sections with straight connecting flanges P by dividing it at points where the side strips join the plates in a straight edge.
