Title: Process for production of lubricating oils
IPC: C10G21/00
Filed: 1962-12-18
Abstract: Naphthenic type lubricating oils are obtained by subjecting a mixed base lubricating oil distillate fraction to a solvent extraction and dewaxing treatment, the solvent extraction including the steps of extracting with an aromatic-selective solvent, for example, phenol, furfural, liquid SO2, nitrobenzene, and nitroparaffins, in a first stage to obtain a first extract phase, which extract phase is then separated into a second extract phase and a second raffinate phase, from which raffinate phase most of the paraffinic and aromatic compounds have been excluded, and hydrogenating the dewaxed second raffinate in the presence of a catalyst.  The dewaxing step may either precede or preferably follow the solvent extraction.  The separation of the first extract phase may be effected by at least one of the steps of cooling and injection of anti-solvent, for example water, if desired with concomitant extraction with an aromatic-selective solvent. The dewaxing may be effected by means of a solvent, e.g. MEK-toluene, or by urea adduction. The hydrogenation is preferably effected at 1000-3500 p.s.i.g., 600-750 DEG  F., WHSV 0.25-3.0.  Any conventional catalyst may be used, the preferred one being cobalt molybdate or alumina.  The product preferably has a specific dispersion of 105-140.

[Also in Division B1] Collagen dialysis membranes are produced by extruding an aqueous dispersion of collagen fibres (or a mixture of such a dispersion with an aqueous collagen solution) through a die having an annular extrusion orifice into a concentrated aqueous solution of an inorganic salt to coagulate the dispersion in the form of a tubular film, irradiating the film with ultra-violet light, immersing the film in an aqueous solution of one one more inorganic salts, the pH of which is adjusted to a value of from 8 to 12 by a buffering agent, washing the film with water to remove the salts, immersing the film in a dilute aqueous solution of glycerine and drying the film. In a modification of the process the irradiation of the film with U.V. light may be effected after the immersion of the film in the glycerine solution and the drying of the film. In the modified process the dried film may be again immersed in water and the wet film thus obtained may be irradiated with U.V. light and dried. Alternatively, in the modified process the dried film may be immersed in a chromium tanning solution, washed with water and dried. The film obtained by any of the above processes may be treated with an aqueous solution of a blood anticoagulant such as heparin or dextran sulphate. The pH of the solution may be from 2 to 5. The aqueous solution containing the blood anticoagulant may be added to the collagen fibre dispersion (or to a mixture of the dispersion and the collagen solution) from which the tubular film or membrane is formed and treated in the manner previously described.

Abstract: 487,542. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. May 19, 1937, No. 13972. Convention date, May 20, 1936. [Class 38 (v)] In a thermostatic device for controlling the temperature of an iron or oven or like apparatus by automatically cutting off the heat supply each time the temperature reaches a maximum, means are provided for preventing the overheating that is likely to occur during the first heating up of the iron from cold owing to the fact that the bimetallic strip which is heated by conduction from one end has not yet attained its final saturated temperature. This object is achieved by providing the bimetallic strip 10 with a reversed end portion 10b which tends with change of temperature to move in a direction opposite to that of the main portion 10a. In the form shown applied to an iron, the portion 10b carries a contact 21 adapted to bridge two contacts 22. A spring 15 gives a quick action and temperature adjustment is effected by rotation of a screw 20 which rocks the frame 17 carrying the one end of the spring, about its pivot 18. In a modification, Fig. 3 (not shown), the invention is applied to an oven, the outer portion of the bimetallic strip projecting from that part of the oven which is heated. A spiral spring also replaces the spring 15 and the adjusting knob serves to rotate " fixed " end of the bimetallic strip. Specifications 144,767, [Class 37], and 487,557 are referred to.

Abstract: 1528700 Electronic timer DAINI SEIKOSHA KK 25 Nov 1976 [27 Nov 1975]  49227/76 Heading G3T An electronic timer particularly for games, comprises down-counters 13, 14, 15, Fig. 3, the counter 15 serving to memorize a 10 minute half-time rest period while counters 13, 14 memorize 40 min and 20 min periods respectively. A switch 32 is operable to select either the counter 13 for timing each half of a football match or the counter 14 for timing basketball, and accordingly a display portion 5, Fig. 1, is activated to show either a footballer or basketball player in action. A digital display of remaining time is given and an alarm generator 23 (e.g. a buzzer) is activated when the display shows 00.00. The counting sequences are controlled by a shift register 22. With switch 32 closed to select basketball counter 14, a switch 18 is momentarily closed at the start of a timing period thus providing a shift pulse so that output Q 2  of SR 22 becomes "1". The resulting output of AND 30 releases a reset on counter 14 which begins counting 1 Hz pulses from a frequency divider 11 fed by an oscillator circuit 10. At the end of the 20 min period, the counter 14 produces a signal which causes activation of the alarm and shifts SR 22 output to Q 3 . Thereby counter 14 is reset and the reset on counter 15 is released so that it begins to count the 10 min interval at the end of which counter 15 likewise produces a signal to shift SR 22. Thereupon counter 14 begins to time the second half of the game. The counting of any period can be temporarily interrupted by opening a switch 12.
