Title: Improvements relating to the refining of mineral oils
IPC: C10G21/18
Filed: 1936-05-21
Abstract: Mineral oils are extracted with dichlorodifluormethane to remove asphalt, if present, and to remove aromatic and unsaturated components.  For the latter treatment other solvents such as sulphuric acid, phenol, cresol, chlorphenol, aniline, quinoline or dichlorethyl ether with which dichlorodifluormethane is not wholly miscible, may be present.  Example; a residual oil is heated at 130 DEG  F. with liquid dichlorodifluormethane under pressure.  After standing, the upper layer of asphaltenes and some solvent is removed and the solution chilled to precipitate the wax which is removed by filtration.  The oil is further treated with a mixture of dichlorodifluormethane and phenol at 104 DEG  F., whereupon two layers are formed.  The raffinate layer is removed and again extracted with phenol to yield a purified lubricating oil, which may be further treated with a bleaching clay.  Unstable constituents are removed from oils by treating with dichlorodifluormethane and sulphuric acid.  Specification 373,538 is referred to.

Patent GB-612164-A (GB)
Title: Improvements relating to automatic air-flow control means, particularly for use on aircraft
IPC: B64D13/00
Filed: 1946-05-14
Abstract: 612,164. Fluid-pressure servomotor-control systems. SEGRAVE, C. R., WILLIAMS, T. B. GLYNNE-, and BARKER, H. H. May 14, 1946, No. 14505. [Class 135] An airflow control device, particularly for use on aircraft wherein a substantially constant weight of air is automatically supplied to an apparatus irrespective of changes in altitude of the aircraft and in the back pressure of the apparatus being supplied. As shown, a valve casing 1, housing a double-beat lift valve 4 normally held off its seat by a spring 8, is disposed in a duct having an intake 2 and an outlet 3 to the apparatus being supplied. The valve casing is surmounted by a diaphragm chamber 7 connected to the valve 4 by a spindle 6 and subjected on its underside, through ducts 19, 20, to the pressure in the outlet, and on its upper side to the intake pressure through ducts 13, 12, 10 under the control of a valve 14 normally held on its seat by a spring 15 and the back pressure of the apparatus through a duct 29, and a casing 28 having a connection 30 to the apparatus. The valve 14 has a stem 16 which coacts with a diaphragm 17 in a chamber 18 above the chamber 7. The underside of the diaphragm 17 is in open communication with the outlet 3, whilst its upperside is exposed to the back pressure through a hole 31, and also loaded by a spring 21, the pressure of which depends on the difference in pressure on the two sides of an evacuated bellows 26 in a casing 25 open to the atmosphere. In operation, air entering the intake 2 passes through the normally open valve 4 to the underside of the diaphragm 9, thus tending to close the valve 4, against the spring 8, the strength of which predetermines the weight of air passing. Should the pressure of the atmosphere decrease, e.g., through increase in altitude of the aircraft, the bellows 26 will expand downwards to move the diaphragm 17 into contact with the stem 16 of the valve 14 which is opened to permit air from the intake 2 to load the upperside of the diaphragm 9 and thereby increase the opening of the valve 4 to compensate for the decrease in pressure. Also, should the back pressure of the apparatus being supplied increase this increase will act on the upper side of the diaphragm 17 to open the valve 14 and on the upperside of the diaphragm 9, to increase the opening of the valve 4 to maintain the same pressure difference between the supply and back pressures of the apparatus.

Title: Improvements in or relating to the production of fibres of thermoplastic materials, particularly glass fibres
IPC: C03B37/06
Filed: 1949-06-02
Abstract: <PICT:0657942/IV (a)/1> A process for producing fibres of an organic or inorganic thermoplastic substance comprises subjecting a stream 4 of the substance, e.g. glass, to the action of gaseous jets 2, e.g. air or steam, forming a bundle about the stream 4, the axes of the jets not intersecting that of the stream, but being inclined to it and bearing on a closed line 3 surrounding the stream 4 to form a constriction in the bundle.  Preferably the jets 2 lie on the generating lines of a hyperboloid of revolution.  The lowering of pressure produced in the space within the line 3 and the rotation imparted to the stream 4 serve to separate it into fibres.  The process is carried out by an annular chamber having outlet orifices suitably disposed in its lower wall, and supplied with gas under pressure.  The stream 4 passes through the central free space formed by the chamber.

Title: Cooling system with means for monitoring coolant flow
Inventor: BODGE C
IPC: G01N25/00
Filed: 1970-04-01
Abstract: 1310904 Alarm systems TEXAS INSTRUMENTS Inc 1 April 1970 [1 April 1969] 15424/70 Heading G4N In a cooling system, the flow of coolant is monitored by a positive temperature coefficient thermistor having a greater rate of increase of resistance above an anomaly temperature than below it. The thermistor is heated by current through a series resistor so as to attain a temperature below the anomaly temperature in the presence of a first level of heat transfer to the coolant and to a temperature above the anomaly temperature in the presence of a second level of heat transfer. As shown in Fig. 6, a positive temperature coefficient thermistor 10 carries sufficient standing current to operate in its self-heating region and is situated in a fluid flow channel. Increase in thermistor temperature due to variation in the fluid medium causes breakdown of voltage regulator diode 54 and conduction of transistor 52 which operates a visual or audible indicator 56 or a relay which controls a load circuit. Transistor 52 also releases transistor 46 so as to extinguish the normal indicator lamp 50. Fig. 8 shows a flowmeter in which PTC thermistor 10 is heated by an auxiliary PTC thermistor having a lower anomaly temperature. SCR 70 becomes conductive when the heat exchange between thermistor 10 and the fluid medium becomes reduced. In Fig. 7 (not shown) three PTC thermistors are coupled via a diode OR gate and a Zener diode to the gate of an SCR.

Title: Improved reinforced rubber structure
IPC: B29C70/04
Filed: 1963-04-19
Abstract: 1,010,971. Laminates. GOODYEAR TIRE & RUBBER CO. April 19, 1963 [May 1, 1962], No. 15488/63. Heading B5N. The bonding between rubber or synthetic rubber and reinforcements, particularly cords or wires of rayon, nylon, polyester or steel, is improved by applying to the reinforcement an aldehyde/polyfunctional or other heat-reactive resin capable of being cross-linked by an aldehyde or other agent to a thermoset condition and incorporating in the rubber &c. a material having the cross-linking properties. The synthetic rubbers used may be polymers of butadiene, isoprene, 2-methyl-pentadiene-1,3, 2- methyl-pentadiene-2,4, or of piperilene, or butyl rubber, or butadiene-, styrene, or acrylonitrile copolymers, or stereo rubbers such as cis-1,4-polyisoprene or cis-1,4-polybutadiene. The resin used may be an aldehyde-deficient condensation product of a polyhydric or other phenol, or of urea or melamine, with an aldehyde such as formaldehyde, acrolein, glyoxal, furfural, crotonaldehyde, aldol, benzaldehyde, or with hexamethylene tetramine or hexamethoxy methyl melamine; suitable phenols being resorcinol, cresol, catechol, phloroglucinol, saligenin, beta- and dibeta-naphthol, xylenol, 4,6- and 2,5-dimethyl resorcinol, hydroquinone, furfuryl, alcohol, orcinol, pyrogallol, aminophenol, and guaiacol. The resin may contain a proportion of rubber latex. Alternatively a phenolic/aldehyde resin-blocked polyisocyanate (which yields the resin on heating) may be used, with or without rubber latex. In an example a polyester cord was passed through a composition made by adding an aldehydedeficient reaction product of resorcinol and formaldehyde to a latex of styrene/butadiene/ 1,3-vinylpyridine terpolymer and then adding a resorcinol/aldehyde reaction product which has been reacted with polymethylene polyphenylisocyanate (a mixture of isocyanates). The treated cord was embedded in a rubber mix comprising natural rubber with common compounding ingredients and containing also hexamethylene tetramine and resorcinol, and the rubber cured at 310 F. The products of the invention comprise tyres, machine and conveyer belts, and hose.
