Abstract: 1445498 Recovering used lubricating oils M FAINMAN and C S MCAULEY 25 July 1974 [30 July 1973] 32969/74 Heading C5E Used lubricating oils are treated by diluting with a hydrocarbon liquid diluent, mixing the diluted oil with a mixture of water and an alcohol, (which alcohol has a water solubility of at least 20% by volume) containing an amount of an acid sufficient to displace polyvalent metal ions from metallic soaps in the oil, and centrifuging the mixture to separate the diluted oil phase from the alcohol-water phase and sludge. In examples used automobile crankcase oils are treated using naphtha, kerosene, xylene or dehydrated overhead from the oils, as diluents; ethanol, isopropanol or tert-butanol as the alcohol; and hydrochloric, sulphuric, nitric, phosphoric, formic or acetic acids as the acid. The process can be used to treat used oils which have been previously treated by the process of Specification 1,445,264 which is similar to that of the present invention except that an ammonium or alkali metal base is used instead of acid.

Abstract: 895,357. Cutting by spark discharge; copyturning. HALLEWELL, H. S. Sept. 14, 1960 [Sept. 29, 1959], No. 33091/59. Addition to 824,735. Drawings to Specification. Classes 83 (3) and 83 (4). A spark erosion machine having a rotary disc electrode mounted on a horizontal spindle is provided with forming apparatus as described in the parent Specification for cutting the required profile on the edge of the electrode. The forming apparatus is mounted on the bearing housing of the spindle and consists of a cylindrical stylus pin engaging a template and connected by a pantograph to a member supporting a cutter e.g. of high-speed steel, tungsten carbide, ceramic or diamond having a radiused cutting edge. The template is an exact reproduction in reverse but scaled in accordance with the pantograph ratio of the required profile of the workpiece. The stylus pin and cutter are so selected that the cutter radius is greater than the quotient of the pin radius and the pantograph ratio by an amount equal to the required spark gap. Thus using the same template and cutter by the use of different sized stylus pins, the electrode can be profiled to the shapes required for say a spark gap of 0.005 inch for rough cutting or a spark gap of 0.0002 inch for finish cutting. The electrode is of copper brass graphite or carbon or a composite structure having an electrically conducting periphery.

Abstract: 773,812. Pens for recording-instruments. FOXBORO CO. Nov. 17, 1954 [Nov. 20, 1953], No. 33308/54. Class 146(3). [Also in Group XIX] An instrument arm carrying a pen, stylus, or indicating finger is adapted for connection to a driving member, such that the pen &c. provides an indication of the movement of the member, the arm being prestressed along a portion 43 adjacent the driving member to render it both less resistant to longitudinal bending and torsionally more rigid, a second portion 45 of the arm, between the pre-stressed length and the opposite end, being reinforced against longitudinal bending. As shown, an instrument arm 38 carries a pen 48 having a V-shaped cross section secured to the arm by a clamp 49 and wire support 50. The portion 43 may be prestressed by peening 44 along the centre line of the arm to place the central portion of the arm in compression and the side margins in tension, thereby decreasing bending resistance about a transverse axis along the portion 43, but increasing torsional resistance about the longitudinal axis of the arm 38. Alternatively, prestressing may be effected by rolling a strip of plano-convex cross section between cylindrical rollers to flatten the strip, thereby compressing the centre portion, or rolling a strip of rectangular cross section between crowned rollers or rollers having central beads. The portion 45 is reinforced by forming a centrally disposed curved ridge. U.S.A. Specification 2,648,895 is referred to.

[Class 69 (i)] To close the space between the floating cover 11 and the wall 10 of a tank used for storing volatile liquids, there is provided a flexible stainless steel sealing ring 12 and a fabric sealing member 58. Flexibility of the ring is ensured by flexures 14 in the form of loops widely spaced around the ring. Each portion of the ring between adjacent flexures 14 is pressed against the wall 10 and is supported by hangers 13, which may act on the centre of a T angle bar 27 that is loosely connected between adjacent flexures. Each hanger 13 consists of a spring-urged tube sliding freely within a tube 37 carried by a tube 46 rotatably mounted on a bracket 47 adjustably attached to the cover 11. Part or all of the turning moment on the bracket 47 due to the weight of the ring is counter-balanced by a spring 55 which also opposes any lateral rotation of the tube 37. The T-bar may be eliminated, one or more hangers then acting in the vicinity of each flexure member. The portion of the ring between each flexure preferably, when in the unstrained position, has a different radius of curvature to that of the tank wall. The flexures 14 may be plugged with vapour impervious material.

Filed: 1960-09-29
Abstract: 919,465. Photo-typesetting machines; lens mountings. HARRIS-INTERTYPE CORPORATION. Sept. 29, 1960 [Sept. 29, 1959], No. 33476/60. Addition to 895,283. Classes 97 (1) and 98 (1). In a photo-typesetting machine as claimed in the parent Specification, the pair of lenses are so spaced apart that a real image of a character on the matrix is formed between them. A pair of independently movable auxiliary lenses may be provided between the record material and the main pair of lenses. As shown, the lenses 120, 122 correspond to the lenses 20, 22 of the parent Specification, and are mounted for axial movement in the same way, so as to occupy one of a number of different positions, thus giving different magnifications. The lenses in the parent Specification are assumed to operate as a composite variable power lens in which no real image is formed between the lenses. The lenses 120, 122 in the present arrangement are disposed so as to form a real image between them, and the necessary conditions are discussed. A further auxiliary pair of lenses 180, 182 are provided, between the first pair and the sensitive sheet 116. Each of these lenses 180, 182 can occupy one of two alternative positions, and can be moved by a fluid motor controlled by a solenoid-operated valve. They can provide gross steps of magnification such as 1: 1, 2: 1 or 4:1, and thus, in conjunction with the original pair of lenses, give a much larger range of magnifications. One or both of the prisms 115 which space the light beam into its proper position on the sheet 116 may be movable laterally, so as to bring the character image, whatever its size, against a fixed alignment reference mark. Specification 839,322 also is referred to.

Filed: 1929-11-04
Abstract: 331,468. Selden Co., (Assignees of Jaeger, A. O.). Dec. 22, 1928, [Convention date]. Catalytic apparatus. - Apparatus for carrying out exothermic catalytic gas reactions comprises one or more layers of catalyst which are cooled by means of the reaction gases, followed by one or more layers of catalyst which are cooled by means of a medium other than the reaction gas issuing from the first layer or layers. The .cooling medium for the second layer may be the reaction gas before passing through the first layer or it may be an independent medium. The cooling means in the first layer are preferably of the double counter-current type and the cooling means in the second layer may also be of the same kind. In the embodiment shown in Fig. 1, closed tubes 4 extend through the catalyst layer 3 and for some distance below it and the reaction gas is fed to the bottoms of these tubes by the inner tubes 5 so that it undergoes indirect and direct heat exchange with the .catalyst before passing through it. Instead of separate pairs of concentric tubes, concentric annuli may be used. The heat-exchangers may be so arranged that they are less effective near the periphery of the apparatus where surface cooling occurs. The independently cooled catalyst layer 8 is cooled by the passage of gas through concentric tubes 10, 11. The apparatus is particularly suitable for the production of sulphur trioxide, but may also be used for many other processes such as organic oxidations, ammonia purification, reductions, hydrogenations, condensations, the water gas process, and the synthesis of hydrocyanic acid. Specifications 283,887 and 306,442 are referred to.
