Title: Process for removing metallic contaminants from oils
IPC: C10G29/12
Filed: 1958-07-04
Abstract: A process for removing non-volatile metallic contaminants from a petroleum oil, a major proportion of which boils above 950 DEG  F., comprises the steps of contacting the oil with a gaseous or 3 to 37% wt. aqueous hydrogen halide in proportions such that no acid sludge is formed and the metallic contaminants are selectively coagulated and thereafter separating the oil from the acid and coagulated contaminants.  The process may be operated at 0-150 p.s.i.g. and 30-300 DEG  F.  The hydrogen halide may be the chloride, bromide, iodide or fluoride, e.g. gaseous or 3-18% aqueous HCl. The oil may be an asphaltic fraction which may be deasphalted prior to or simultaneously with the hydrogen halide treatment. The separated asphalt and the deasphalted oil may be recombined and treated together (the deasphalting step apparently destroying coagulation inhibitors).  Volatile metal contaminants may be converted to a non-volatile form by a pretreatment, e.g. heat-sealing at 300-750 DEG F.  The oil may also be pretreated by a hydrotreating process, e.g. with excess hydrogen at 500-900 DEG  F. and 200-800 p.s.i.g. with a feed rate of 1-5 V/V/H. and H2 rate of 1000-15000 SCF/Bbl. using a molybdena or cobalt molybdate on alumina catalyst.  The treated oil may be stripped with an inert gas and ammonia and washed with caustic soda or saturated aqueous magnesium sulphate solution.

Title: Digital transducer system
IPC: G02F1/03
Filed: 1960-06-20
Abstract: 892,376. Electrical selective-signalling systems. GENERAL ELECTRIC CO. June 20, 1960 [July 30, 1959 (2)], No. 21543/60. Class 40 (1). A transducer for converting stress (mechanical or electrical) into electric digital signals is characterized in that the stress is applied to a substance having the property that the plane of polarization of a beam of light passed through the substance is continuously and cyclically rotated as the applied stress is gradually increased, and in that electrical means responsive to the rotation of the plane of polarization of light having passed through the substance are provided for producing a digital output. According to the Specification the extent of the rotation of the plane of polarization of light transmitted by such a substance (e.g. cellulose nitrate, epoxy resin or polyurethane rubber) is proportional to the stress, i.e. force per unit area, applied to the substance so that by applying a force F, Fig. 2, to a sample 1 of the substance shaped as shown, different regions A, B and C of the sample will produce different angles of rotation of the plane of polarization. As described, the sample 1 is so shaped that when three polarized beams of light from lamps 5 and filters 8 are passed through the sample 1 and analysed by further filters 11 inclined at 90 degrees to the first filters, the combination of signals produced by three photo-electric cells 14 represent, after being applied to three voltage discriminators, the magnitude of the applied force F in a monophylic binary, code. In the preferred form of this embodiment, to avoid errors which might arise due to variations in the intensity of the light produced by lamps 5, two photoelectric cells 43a, 43b, Fig. 4, and two analysing filters 4Oa 40b, inclined at 90 degrees to each other, are used for each beam of light, and each pair of cells is so arranged in a bridge circuit 57, Fig. 6, that a transistor 59 only becomes conductive to energize a neon indicator lamp 70, when a " one " is to be signalled. In three further embodiments differential stressing is produced by shaping the sample as shown in Figs. 13, 22 and 23. It is also stated that similar results can be achieved by using uniform stressing but by making the several beams travel differential distances in the substance as in Fig. 14. The stress could be produced electrically, by pairs of electrodes 174, Fig. 18, in a liquid such as carbon disulphide, chloroform or acetone.

C. ; 94, Bayview Avenue, Port Washington, New York, U.S.A.) July 25, 1934, No. 21706. Convention date, Aug. 2, 1933. [Class 40 (ii).] The vertical pivot of a pick-up arm is resiliently supported, lateral vibrations are prevented, and vertical vibrations are damped. When the horizontal pivot 15, Fig. 2, is in line with the vertical pivot, this pivot 12 is mounted on a ball 30 over a spring 29 in a rubber bearing 25 which prevents lateral vibrations and damps vertical vibrations. The removal of the pivot is prevented by a screw 27. When the horizontal pivot 34, Fig. 4, is to one side of the vertical pivot, this pivot 35 is mounted over a spiral-shaped spring 36 and held laterally between a pair of ball races 42 in a perforated cage 43 supported by an intermediate point of the spring 36 so that the vertical vibrations of the pivot 35 are damped by friction while lateral vibrations are prevented. The distance between the top and bottom ball races determines the amount of friction. The pivot is detachably kept in its mounting by a loose bayonet-joint 39, 40.

Headings G1M and G1N. Apparatus for measuring or indicating lack of straightness along a nominally flat test surface comprises a carriage mounted for traversing movement along on at least generally straight guide, a feeler carried by the carriage for engagement with the test surface, the feeler being mounted for movement relative to the carriage in a direction generally normal to a datum plane, to execute a working movement during traversing in accordance with the lack of straightness of the test surface in the traversing direction, and means operable at will for deflecting the feeler across the test surface in a direction transverse to the traversing direction to test that the test surface lies in a plane generally parallel to the datum plane. As shown in Fig. 1, the carriage C, has two pairs of bearing elements E which bear on optically flat surfaces B<SP>1</SP>, B<SP>2</SP> of a glass or metal guide B. The carriage may be hand or motor driven and is supported by spring-loaded rollers F. The feeler D is mounted on a frame H supported by ligaments (J), Fig. 2 (not shown), formed with a set for urging the feeler downwards. An abutment H<SP>1</SP> on frame H co-operates with one end of a lever K, the other end of which carries a moving element (M<SP>1</SP>) of an electrical detector. To avoid overloading the detector, stops are provided to prevent unduly large movements of lever K. A second detector Q generates correcting signals from roller N traversing a plastics cam surface P set by a plurality of screws P<SP>2</SP> during a test run on a known straight test surface. The outputs of both detectors are fed together through an amplifier to a pen recorder. To check that the test surface is parallel to the datum plane, a solenoid R<SP>1</SP> is energizable repeatedly by a motor driven cam to attract a magnetically soft armature R thereby oscillating the feeler carraige in a direction transverse to the traversing direction. Casing A has three adjustable feet (not shown). In an alternative, Fig. 3 (not shown), the carriage (T) has a V-bearing defined by two axially-spaced pairs of bearing elements (T<SP>1</SP>) which bear on an accurately straight guide shaft (S). The feeler (W) is located normal to the bisecting plane of the V-bearing. The deflecting means comprise a bearing element (T<SP>4</SP>) which engages a supplementary guide (X) which is rotatable about an eccentric axis (X<SP>1</SP>). The bearing element (T<SP>4</SP>) may be adjustable by hand. No correcting signals are provided in this embodiment.
