Title: Improvements in apparatus for supplying liquid to a chamber such as oil to an enginecrank case and for governing the liquid level therein
IPC: F01M11/06
Filed: 1919-09-06
Abstract: 143,454. Hansen, V. N. L. Sept. 6, 1919. Levels, regulating.-The supply of liquid to a chamber (e.g. oil to an engine crank-case A) and the level of the liquid therein are controlled by means of the float chamber 2, which supplies oil to the crank case through an orifice 23. This orifice is arranged above the bottom of the float chamber, so that if the relative levels of the float chamber and crank-case are altered (as by the tilting of a road vehicle on an incline) the flow to the crank-case will cease as soon as the level therein reaches the position indicated by the line X. A valve 24 may be arranged as shown to maintain the orifice 23 closed as long as the engine is running, by the action of suction transmitted through a pipe 30, for which an electrical device may be substituted. The float valve closing the inlet to the float chamber has a three-cornered stem as shown ending in a conical point.

Abstract: 800,165. Slings for handling loads. EASTERN ROTORCRAFT CORPORATION. July 17, 1956 [July 18, 1955], No. 22133/56. Class 78 (4). [Also in Group VIII] A cable sling net is so constructed that it may be opened out into a box-shaped container, the meshes of the net being disposed diagonally with respect to the edges of the container, and the container having a bottom and side walls constituted by portions of net connected together at mesh corners disposed along edges of the container. As shown in Fig. 2, the meshes are joined to each other by fittings 30 which are normally disposed horizontally, except those on the vertical edges of the container, which are disposed vertically. The bottom and two opposite side walls are formed as one portion of net, with the fittings all parallel. In a modification, Fig. 4, for dropping loads by parachute, a plastic tray 44 completely encloses the bottom and lower part of the walls of the net. Triangular extensions of the walls carrying hooks 54 and eyes 55 enable the net to be closed at the top, and cables attached to rings 59 allow suspension from a parachute. Cables 56, 57 and 58 pass diagonally through the plastic base to 56a, 57a and 58a, respectively, and similarly at the other three corners of the base. The base is made in the form of a sled, witH towing eyes 63 and brackets 49 which engage under members 65, Fig. 7, fixed to an aircraft floor. The floor also has rollers 66 for easy unloading.

Abstract: 702,123. Presses for separating liquids from solids. MOOS, G. Sept. 4, 1952 [Oct. 18, 1951], No. 22242/52. Class 46 Resilient distance pieces arranged coaxially form, in conjunction with perforations in the filter plates of a press, on uninterrupted conduit for withdrawal of filtrate or admission of air or wash liquid. The interior of the conduit communicates with the interior of the apparatus only through the filter layers on the plates. The distance pieces may comprise rubber sleeves 7 held in contact with plates 2 around holes 4. Fig. 1, by springs 9 which yield under the compressing pressure. Alternatively linkages 11, Fig. 4, connected at the centre by compression springs 12 may be substituted for the springs 9. Before compressing pressure is relieved the material occupying the inlet openings 3 is forced into the region between the plates 2 by a piston 5. Filtrate is collected in and discharges from a container 13, the outflow pipe from which is controlled by a four-way cock 14 so that only when the outflow pipe is closed can compressed air be passed into the filter plates from a cylinder 15. The openings 3 may be dispensed with and a filling conduit 18 communicating with all the inter-plate spaces provided. In this case the press lid 16 has a projection 17 which compresses material in the conduit 18. The filter plates may each have on each side a layer of absorbent resilient material such as asbestos or infusional earth and a rubber or sheet metal frame.

Patent GB-479916-A (GB)
Title: A process for the extraction of heavy hydrocarbon oils with the aid of selective solvents
IPC: C10G21/00
Filed: 1936-08-14
Abstract: Lubricating-oils are submitted to "intense extraction" with a polar selective solvent to produce an extract and a raffinate, whereupon the extract is treated to separate paraffinic hydrocarbons dissolved therein and these are added to the raffinate to form an improved lubricating oil.  "Intense extraction" consists in effecting extraction under such conditions, (e.g. repeated extraction at increasing stages of temperature) that the ratio Viscosity E50 of the raffinate: Viscosity E50 of the extract, is greater than 1.  Extracts so obtained, in addition to the usual non-paraffinic constituents, contain also low and medium molecular weight paraffins and high molecular aromatics which are difficult to remove.  The latter cause "ring sticking" and are responsible for poor Couradson carbon value. The valuable medium molecular weight paraffins are recovered from the extract by distillation with a preferential solvent for aromatics if necessary, or by treating with a low molecular substance, e.g. propane under para-critical conditions as described in Specification 471,213.  The "intense extraction" may be preceded by a normal extraction step, or series of steps to remove the bulk of the undesired constituents. Oils containing paraffin wax and asphalt may first be freed from these substances, but this is not essential, in which case the asphalt is removed with the extract and the final raffinate is dewaxed.  Polar selective solvents specified are; liquid sulphur dioxide, furfurol, nitrobenzene, benzonitrile, aniline, chlor-aniline, crotonaldehyde, cresol, "chlorex" (Registered Trade Mark), or mixtures of these alone or together with diluents such as benzene, carbon disulphide, ether or carbon tetrachloride. In an example, a de-asphaltized oil residue is extrated at 90, 120, and 130 DEG  C. with an equal amount of furfurol or nitrobenzene at each stage.  A combined extract (67 per cent by vol.) of E50 6 and a raffinate (33 per cent) of E5015 are obtained \baR/E\be = 2,5.  The extract is distilled in vacuo, leaving the high molecular aromatics as residue, and the paraffinic distillate (59 per cent by volume) is added to the raffinate.  This is then dewaxed with benzene-acetone, and then finally treated with sulphuric acid and petroleum ether as diluent, caustic soda, and bleaching earth.  The product had a Couradson Carbon Test of 0,44.

Title: Improvements in or relating to corrosion inhibitors
IPC: C23F11/08
Filed: 1957-07-19
Abstract: 865,192. Preventing corrosion. ALBRIGHT & WILSON (MFG.) Ltd. July 19, 1957 [July 27, 1956], No. 22897/57. Class 123(1) The corrosion of copper or its alloys in water systems is prevented by adding to the water from 0À5 parts to 5À0 parts per million of an inhibitor consisting of a water-soluble 1,2,3,- triazole, the preferred substance being 1,2,3,- benzotriazole. Where iron or steel are present in the system, small amounts, for example, 25 parts per million of an alkali metal molecularly dehydrated phosphate such as sodium phosphate glass may also be added to the water. The triazole inhibitor, which is most effective in water of a pH range of 5 to 7 inhibits corrosion of copper and also rapidly reduces the galvanic attack of steel coupled to cuprous metals, the latter effect being most marked when the phosphate is also present. The inhibitor reduces the dissolving of copper by the water and so reduces the deleterious action of dissolved copper on the corrosion of more anodic metals such as steel, zinc or aluminium. In cooling installations where mercury salts tend to contaminate the water, the triazole inhibitor prevents the deposition of mercury and mercury salts on both copper and aluminium. The inhibitor with or without the phosphate is effective in waterrecirculating systems employing chloramine as a purifier, the protective film of benzotriazole on the copper being unaffected by the chloramine.
