Title: Process for the production of lubricating oils suitable for refrigerators
IPC: C10G67/06
Filed: 1963-12-16
Abstract: Lubricating oils suitable for refrigerators are produced by extracting a straight-run mineral oil fraction, boiling in the lubricating oil boiling range, with an aromatics-selective solvent to obtain a raffinate containing less than 8 % wt. polyaromatics, catalytically hydrodesulphurizing the raffinate under mild conditions, i.e. such that whilst sulphur and oxygen compounds are hydrogenated the hydrocarbons remain substantially unaffected, and thereafter contacting the hydrodesulphurized raffinate with a solid adsorbent, for example, fuller's earth, activated clay, or activated alumina.  Desirably, at some stage prior to the adsorbent treatment, the oil is dewaxed.  Low-boiling constituents of the hydrodesulphurized raffinate may be removed by distillation or by stripping with steam.  The hydrodesulphurization may be effected at 290-375 DEG  C., 30-105 ats. g., L.H.S.V. 1-4, and 45-215 Nm3 H2 per m3 raffinate.  The extraction is preferably effected at 25-100 DEG C., for example with phenol, sulphur dioxide, or furfural.  On oxidation, inhibitor preferably of the phenolic type such as 2,6-ditertiarybutyl-4-methyl phenol, may be added to the finished product.  Specification 657,521 is referred to.

Abstract: 1,241,174. Evaporators, flash type; desalination of water. BRITISH OXYGEN CO., Ltd. 4 Nov., 1968 [3 Nov., 1967], No. 50118/ 67. Heading BIB. Fresh water is obtained by passing salt water from pump 31 through a heat-exchange coil 22 wherein it is heated by hot compressed ammonia vapour (or sulphur dioxide or a fluorinated hydrocarbon) flowing through heat exchanger 19, and then passing the heated salt water through line 32 into chamber 11 where it flows down over trays 15 and undergoes partial vaporization; the vapours condense on heat-exchange coil 12 and the distillate (fresh water), collected in tray 13, is withdrawn through line 40. The liquified ammonia leaving heat exchanger 19 flows through expansion valve 16 into heat-exchange coil 12, and then enters reservoir 17. Ammonia vapour is withdrawn from reservoir 17 by compressor 18, and is recycled to heat exchanger 19. Some of the brine withdrawn from chamber 11 through line 35 is discharged from the system through line 36, but a major proportion is recirculated to coil 22. Make-up salt water is supplied by line 29. This make-up water may be used to provide additional cooling for heat-exchange coil 12. The mechanical compressor 18 may be replaced by a thermal compressor operating on the vapour-adsorption principle. The vaporization of water may be carried out under subatmospheric pressure maintained by a pump operated by the compressed ammonia or other working fluid. The heat exchanger may be made of copper.

Abstract: 1287127 Transistor amplifying circuits MARCONI CO Ltd 14 Oct 1969 [23 Jan 1969] 50342/69 Heading H3T A power amplifier comprising at least one class A transistor stage incorporates an additional transistor which has its collector circuit connected to the base of the amplifier transistor and which has a negative feedback circuit which includes a resistor which is common to the emitter circuit of the additional transistor and the collector circuit of the amplifier transistor, the additional transistor being arranged to act as a current generator. The arrangement is described as applied to a transmitting amplifier comprising an initial stage Tr 5  coupled by transformer T to a first class A stage Tr7 which is followed by a further class A stage Tr9 and two class C stages Tr11, Tr12 respectively, coupling being by means of low-pass filters pb1-pb3. The emitters of transistors Tr7, Tr9 are earthed, and they obtain base biases via auxiliary transistors Tr6, Tr8 respectively, which are provided with negative feedback by means of resistors R1, R2 respectively. The collector currents of transistors Tr7, Tr9 pass through resistors R1, R2 respectively, so completing D.C. negative feedback loops which render the collector currents of these transistors substantially constant. The biases for the bases of transistors Tr6, Tr8 are derived from a network including the collector current path of a further transistor Tr13 to which a bias can be applied to render transistors Tr6, Tr8 and hence transistors Tr7, Tr9 non- conductive, cutting off the output of the amplifier. This may be utilized to provide overload protection, or if the amplifier is utilized in a radio relay station, transistor Tr13 can be arranged to be controlled by known automatic insertion circuitry for bringing the transmitter of the station into operation when the receiver thereof picks up a signal.

Abstract: 1525950 Spherical particles HOBEG HOCHTEMPERATURREAKTOR BRENNELEMENT GmbH 10 Dec 1975 [16 Dec 1974] 50579/75 Heading C1A A process for the production of uniform, spherical nuclear fuel and/or fertile particles comprises providing an oscillating liquid jet of uranium and/or thorium-containing solution, emulsion or sol issuing from one or more nozzles 8, and subsequently breaking out into droplets 9 at a rate of more than 3000 droplets per minute per nozzle, the droplets first passing through a free-fall zone 1 free from ammonia gas of which the dimensions are such that the droplets have just assumed their spherical form therein, and then passing through a free-fall zone 2 through which ammonia gas flows, the residence time of the droplets in this free-fall zone being less than 0À5 second, and the ammonia gas being introduced into this free-fall zone by means of one or more feed pipes 6 in such a way that the ammonia gas stream is turbulent and comprises a vertical component flowing in the opposite direction to the droplets, and a horizontal transverse component flowing through the gaps between the droplets, the dimensions of this free-fall zone being such that the spherical droplets "harden adequately" before falling into an ammonia solution 10, after which the droplets are dried and sintered. The expression "harden adequately" means that the spherical form of the droplets is sufficiently stabilized by chemical reaction with the gaseous ammonia so as to prevent deformation of the spherical particles when they come into contact with the surface of the ammonia solution. Carbidic particles may be obtained by including carbon black or other finely dispersed carbon powder in the uranium and/or thorium-containing solution, emulsion or sol. The uranium and/or thorium-containing solution, emulsion or sol may also contain fillers, binders and droplet stabilizers. The particles obtained may be coated with pyrolytic carbon.

Patent GB-506881-A (GB)
Abstract: 506,881. Thermionic valves. BORMANN, 0. Sept. 1, 1937, No. 23960. Convention date, Sept. 10, 1936. [Classes 39 (i) and 40 (iii)] A resonating device for producing, amplifying and receiving high-frequency oscillations consists of a hollow conducting body containing. electrodes so arranged that when oscillations are taking place at the desired frequency, corresponding to one of the natural periods of the resonator, the lines of force strike the surfaces of the electrodes substantially perpendicularly. The resonator may have several forms, such as a sphere or a toroid, but the preferred form is a cylinder without a central conductor and with closed ends, the lines of force taking the form of eddy lines constituted by circles lying in planes perpendicular to the axis of the cylinder and concentric therewith. The Figure shows such an arrangement. The electrodes consist of a cathode 7, a flat anode 4 and a grid 5, the two latter being arranged radially in the cylinder. The cathode is protected by a radial screen 6 connected to the grid 5, and the electrons oscillate between the anode and the grid. The electrodes are arranged in antinodes formed by, radial planes. Antinodes also exist in planes perpendicular to the length of the cylinder, and the electrodes are arranged in a region about one of the antinodes. Thermionic electrodes may be replaced by electrodes with secondary emission, or non-emissive electrodes may be employed connected to a diode or other oscillation generator outside the resonator. Instead of being strictly radial the electrodes may be parallel to each other, being either both parallel to a radius between them, or one being radial and the other parallel to it. More than one pair of electrodes may be employed, arranged at such distances and so connected by conductors at the ends of the resonator as to be in proper phase relation. The resonator may be connected with a transmitting device consisting of a tubular dielectric guide 12 connected with the resonator through a slot 10, closed by insulating material, and blocks 11 forming a capacity coupling. The resonator and dielectric guide may be excited to the same or different modes of oscillation. A modification is described in which the dielectric guide is arranged at the end of the resonator instead of at the side, and another in which the resonator is enclosed in an exhausted envelope.
