Title: Laser-doppler anemometer
IPC: G01S17/50
Filed: 1974-04-11
Abstract: 1465816 Laser Doppler anemometers BBC BROWN BOVERI & CO Ltd 11 April 1974 [18 April 1973] 16357/74 Heading G1A In a laser Doppler anemometer two or more beams of light 3, 4, Fig. 1, are derived from a laser 1 and at least one is directed into a measuring volume 7 by a lens system 6; the lens system also collects backscattered light from the measuring volume, and this is directed by mirrors 8, 9 to a photo-detector 12 and an eyepiece 31. The mirror 8 is either formed of light transmissive ellipses in a reflective coating, as in Fig. 2a, or of orthogonal light transmissive strips as in Fig. 2b, or from a combination of ellipses and strips, Fig. 2c (not shown). These mirror constructions enable the beam-splitter 2 which produces beams 3 and 4 to be rotated about the axis of lens system 6 so that flow components in different directions can be measured. The relative intensities of the beams 3 and 4 can be set by reflective coatings on the surfaces of the prisms constituting the beam-splitter, Figs. 3, 4 (not shown), or by filters 5 in Fig. 1. Constructional details of the eye-piece and of an adjustable support for diaphragm 11 in front of the detector 12 are given, Figs. 5, 6 (not shown). The apparatus is removably mounted on a pair of base-plates so that components, e.g. lenses, can be exchanged, Fig. 7 (not shown). The backscattered light can be analyzed with or without heterodyning with an unscattered beam, Figs. 8, 9 (not shown), the latter figure using three beams produced by the beamsplitter. Components in two directions can be measured simultaneously by combining such measurements, using separate detectors. The actual or effective optical separation of the laser and lenses 6 is adjustable so that the minimum spot radius of the laser output is focused into the measuring volume.

Abstract: 236,223. M³ller, W. June 26, 1924, [Convention date]. Angular bending; rtandrels. - In a pipe-bending machine of the kind in which a bending member carrying a supporting mandrel is rotated round a stationary former, the mandrel is given by a stop mechanism a lead relatively to the bending member just prior to termination of the bending operation, so that bending is completed. with the mandrel out of action and bulging of the pipe thus prevented. The pipe a is secured by a clamp w to a stationary former b mounted on a base and the bending member c is carried by a frame d rotated round the former. The frame has an extension h for supporting the mandrel l which is secured to an arm k having a rod i with nuts t for adjusting the position of the mandrel. The mandrel is normally held in the dotted position by a spring n secured at v to the arm k, which is slotted to engage a pin p<1> on the frame d. The frame carries a lever q which is normally in engagement with a stop r. Just prior to completion of the bending operation the short arm of the lever q engages a stop g fixed in a groove f in the base and the mandrel is thus retracted to the position shown. Bending is continued until the lever engages a stop s on the frame d. On releasing the clamp w the pipe is removed and the frame returned to its initial position, the spring n during this operation resetting the mandrel.

Title: Manufacture of 2-methyl-1,3-pentane diol
IPC: C07C31/18
Filed: 1949-06-21
Abstract: 2-Methyl-1,3-pentane diol is prepared by subjecting propionaldehyde to the action of heat in an inert organic solvent medium under a superatmospheric pressure of hydrogen and in the presence of a basic substance and a hydrogenation catalyst.  The process is preferably carried out at a temperature between 200 DEG  and 300 DEG  F. under a hydrogen pressure of from 200 to 3000 lbs./sq. inch, the hydrogenation catalyst being preferably a nickel catalyst, e.g. Raney nickel.  Suitable organic solvents are, for example, propyl alcohol, diethyl ether and acetal.  The basic substance used may be an alkali metal compound such as sodium hydroxide or sodium carbonate or an alkaline earth metal compound, e.g. calcium oxide or magnesium oxide or an organic base such as ethanolamine.  Preferably the quantity of basic substance present is such that the addition to the reaction mixture of an equal volume of water produces an aqueous solution having a pH of at least 7.5.  In the example 2-methyl-1,3-pentane diol is produced by heating propionaldehyde dissolved in propyl alcohol in the presence of sodium hydroxide and Raney nickel under a hydrogen pressure of 800 lbs./sq. inch.

Patent GB-596374-A (GB)
Title: Improvements in photographic roll-film developing tanks
IPC: G03D13/06
Filed: 1944-09-02
Abstract: 596,374. Photographic roll-film developing tanks. BOLSEY, J. Sept. 2, 1944, No. 16755. [Class 98 (ii)] A daylight developing tank has film-receiving and film-developing chambers with an opening between them through which an axiallyslidable film-supporting reel may be passed from one chamber to the other, the reel having an end-disc co-operating with an annular ring on the inner wall of the tank to seal said opening when the reel is in film-receiving position. There may also be provision for sealing the opening when the reel is in developing position. Provision is made for supporting a magazine of exposed film, and for positively feeding the film therefrom through a duct into the film-receiving chamber. The reel may have a spiralled end-disc for receiving an edge of the film in order to hold the film turns spaced apart. As shown, the tank comprises a cylindrical casing 10 having a draining faucet 32 and a light-tight cover 14 with locating pins 20 and securing screws 19. A ring 33 divides the casing into two chambers 11, 12, from one to the other of which may be slid on a tubular post 23 a reel 21 having one end-disc 46 spiralled. The ring 33 co-acts with one or other of the end-discs of the reel to shut off one chamber from the other in the two positions of the reel. The hollow reel axle 25 extends outside the casing 10, where it carries a funnel 29. In the film-receiving position, the reel 21 is held raised in chamber 11 by the out-springing of the slotted upper end of the post 23 into a bevelled recess 51, and is held in correct position to receive the film into the spiral 46 by a pin 48 and cooperating longitudinal groove 47. Adjacent the chamber 11 is an open housing 13 for a film magazine. The end of the film therefrom is threaded through a duct 38, one wall 39 of which is pivoted at 40 to permit the film during threading to pass the teeth of a feed sprocket 42 and thereafter to be pressed so that its feed perforations engage the sprocket teeth. The duct leads to the chamber 11, and with the film entrained in the outer end of the spiral 46, operation of a handle 43 turns the sprocket 42 and feeds the film from the magazine on to the reel, with one edge engaged in the spiral. Developing liquid poured into the funnel 29 passes via the hollow reel axle 25 and holes in the post 23 to the chamber 12 into which the reel is lowered by pressing on the funnel 29. The reel-locating groove 47 opens into an annular groove 49, which receives the pin 48 when the reel is depressed, so that liquid agitation by manipulating the funnel 29 tu rotate the reel is permitted.

Title: Improvements in gauge and method for reading liquid level
IPC: G01F23/292
Filed: 1962-05-02
Abstract: 987,270. Indicating liquid levels. YARNALLWARING CO. May 2, 1962 [July 27, 1961], No. 16868/62. Headings G1H and G1J. For indicating the liquid level in a boiler, a gauge tube has a series of observation ports 51, Fig. 1, each provided with a front glass 40, Fig. 2, and a rear glass 35 defining a wedge-shaped space 30 and illuminated by a lamp 42 and slit 46. The upper part of the gauge tube contains vapour and the lower part liquid so that there is increased refractive deviation in the lower part to give a beam 57 while less deviated beams 50 traverse the vapour-filled part of the tube. These beams fall, respectively, on red and green coloured filters 51, 58 thus producing laterally-displaced bands of red and green light, 62 and 63, Fig. 1, respectively. The front-surface of the filters is made diffusing to give a wide viewing angle. Instead of a single illuminating slit, two or more slits may be used and formed on the back surface of the filters, either by etching or deposition, to produce light striations of the different colours. Alternatively, a lenticulated screen may be used to produce the striations. The colour filters are then in the form of strips of alternate colours, light being focused by the lenticulations on to the appropriately coloured region in dependence upon the direction of incidence of the light. The illuminating slit 46 may be replaced by a cylindrical lens strip extending down the whole length of the gauge tube.
Patent GB-481647-A (GB)
Title: Improvements relating to the treatment of hydrocarbon oils by the edeleanu process
IPC: C10G21/10
Filed: 1937-09-17
Abstract: <PICT:0481647/III/1> <PICT:0481647/III/2> In the extraction of hydrocarbon oils by the Edeleanu process, with sulphur dioxide or mixtures containing it, both the oil and sulphur dioxide are pre-cooled, by causing partial evaporation of the sulphur dioxide and transferring the low temperature produced to the oil by indirect heat exchange.  Separate cooling of the oil and solvent is thereby avoided.  A cooler 1, Fig. 1, is provided with one or a series of pipe coils 5 through which the oil to be treated flows.  Sulphur dioxide passes through an expansion valve 3 to the chamber 1, vapours being removed through a pipe 6 and liquid sulphur dioxide through a pipe 4.  The flow of oil is regulated so that the oil attains the temperature of the chilled sulphur dioxide.  The cooled oil and sulphur dioxide are then led to an extraction tower.  In another form, the oil is led through a pipe 3, Fig. 2, to a heat exchanger 2 and flows through pipes 4 to an outlet at the base.  Cooled sulphur dioxide passes from the bottom of a chiller 1 through a pipe 5 to the bottom of the space surrounding tubes 4, rises and returns through a pipe 6.  Cooled sulphur dioxide passes through a pipe 7 to an extraction tower fed with the oil.  A series of such heat-exchangers 2 connected in parallel with a common cooler 1 may be used, in which case the flow of oil may be increased.  The formation of ice from small amounts of water present in the oil may be prevented by pre-mixing the oil with a small amount of sulphur dioxide.
Patent GB-691691-A (GB)
Title: The use of adsorbents in the refining of oils
Inventor: POTT ANTHONY FRED DORAN
IPC: C10G25/00
Filed: 1950-07-07
Abstract: An oxidation inhibitor is dissolved in mineral oil before it is refined by treatment with an adsorbent, the oxidation inhibitor being chosen from the following classes, viz. phenols, organic amines, organic nitro compounds and organic sulphur compounds. Mineral oils mentioned are insulating oils and steam turbine lubricating oils, while the adsorbent may be an activated clay, carbon, silica, alumina or silica-magnesia mixture.  Specific activated earths mentioned are montmorillonite, attapulgus clay and Florida earth.  The insulating oil may be one thickened with petrolatum, wax, rosin, polybutene or polymethyl methacraylate, or such thickeners may be added after refining.  Phenolic oxidation inhibitors include phenol, diphenol, naphthols and alkylated phenols such as trialkylated phenols, while the organic amines used as oxidation inhibitors include phenolic amines. Organic sulphur compounds which may be employed as oxidation inhibitors include thio-alcohols, thio-ethers, xanthates and thiphosphates.  Oxidation inhibitors for use in the case of insulating oils are preferably those that do not increase the p power factor or reduce the resistivity of the oil, particularly 2, 4, 6 tri-t-butyl phenol, 2, 6 di-t-butyl 4-methyl phenol and 2, 2-bis (31, 51-di-t-butyl 41-hydroxyphenyl) pentane.  Additional substances which may be added to the refined oils are rust and corrosion inhibitors (e.g. metal naphthenates or sulphonates, or certain mercapto-substituted aliphatic monocarboxylic acids), anti-foaming agents (e.g. polymeric silicones), wear reducing agents (e.g. organic phosphates and thiophosphates), detergents (e.g. alkaline earth metal salts of alkyl phenyl sulphides) and metal de-activators (e.g. N, N1 disalicylidene 1, 2-diamino propane).  In examples, 2, 6-di-t-butyl 4-methyl phenol is dissolved in mineral oil, suitable for use as insulating oil or turbine oil, before it is refined by agitation with montmorillonite or Fuller's earth.  Tests are described in which the refined oils of the examples are compared with similar oils which have been adsorbent-refined in the absence of oxidation inhibitors, the latter in some cases being added after refining.
