Title: Improvements in instrument pointers
IPC: G03B7/12
Filed: 1961-07-10
Abstract: 987,410. Mechanical relay and follow-up devices. VOIGTLANDER A. G. July 10, 1961 [July 9, 1960], No. 24966/61. Addition to 878,797. Heading G1J. The scanning device of the parent Specification is modified in that the follow-up pointer 15 is made adjustable for movement in the direction of its length towards and away from the arcuate clamping surface 19 and/or for varying the angle # between the arc swept by the tip 18 of the followup pointer and the arc of the surface 19. To this end the pointer 15 is pivotally mounted on a pin 14 on an upper disc 12 and is urged by a weak spring 16 so that its edge 15a bears lightly against the abutment 17 which is formed as an eccentric. By turning the eccentric 17 the angle α is varied and consequently the angle # also. The disc 12 is concentric with the lower disc 9 which has teeth 10 meshing with the rack 11a on the slide 11 and the disc 12 can be turned relative to the disc 9 by turning an eccentric 20 in the disc 9 in a slot 21 in the disc 12 whereby the space between the tip 18 of the pointer 15 and the clamping surface 19 can be varied. As shown the discs 9, 12 are coaxial with the meter pointer 4 so that α = #. In another embodiment, Fig. 3 (not shown), the axes of the discs 9, 12 are spaced from the meter axis and the centre of curvature of the clamping surface lies on the axes of the discs 9, 12 so that the angles α, # are no longer equal. The arresting surface for the meter pointer is formed on the transparent curve of the meter.

Title: A method and apparatus for continuously refining or improving mineral oils by means of a solid adsorbent
IPC: C10G25/06
Filed: 1957-08-08
Abstract: <FORM:0828649/III/1> Mineral oils are treated with granular solids by a process comprising the steps of conducting the solids contained within a plurality of super-imposed containers from below in the upwards direction by means of a conveying mechanism (see Group XXX) and of conducting the liquid by gravity through the successive containers from above.  The process is particularly applicable to treating crude distillates, semi-refined products or residues and used insulating or lubricating oils boiling above 550 DEG  F. with adsorbents.  Adsorbents mentioned are gamma alumina of grain size 0.02 to 0.2 mm., clays and silicates.  The viscosity of the oil to be treated should be reduced to below 20 cs., preferably 5-10 cs., e.g. by heating or dilution with a neutral solvent such as petroleum ether.  The absorbent is changed to a number of containers 1, with oil-permeable bases, which are arranged vertically above one another in the absorption zone.  Oil is introduced to the top of the zone and percolates through each container in turn and is directed to storage through distributer 24.  At convenient intervals the top container is transferred to washing zone 25, the remaining containers each raised to the next highest position, and a container of fresh absorbent inserted in the lowest position.  The absorbent, after washing-which may be conducted on the same principle as the absorption-is passed through drier 27 and regeneration zone 28 before being reintroduced to the absorption zone.  Suitable wash solvents are gasoline and petroleum ether.  The containers may be partitioned, e.g. in a honeycomb pattern, to prevent channeling.

Abstract: A wound package of sewing thread made wholly or partially of continuous filaments of synthetic polymeric material, e.g. polyamide, polyester and acrylic filaments, capable of being unwound in a substantially untensioned state without twisting on itself, is produced by coating the thread with a solution or dispersion of a water-insoluble curable synthetic resinous organic compound, drying the coating to remove the solvent or dispersant, the thread being maintained in a substantially unstretched state during the application and drying of the coating, winding the thread to form the package and curing the coating, the drying step being carried out before or during the winding step and the curing step being carried out before, during or after winding. Threads comprising a core of continuous filaments with staple fibres spun around the core may be treated.  Solutions of dispersions containing 3-20% by weight of nylon in which some of the amide hydrogen atoms are replaced with methyl methoxy groups and acrylic polymers or copolymers may be used to coat the p  threads.  The coating composition may also contain melamine-formaldehyde resins and catalysts, e.g. ammonium chloride and citric acid.  The drying and curing may be effected by the use of infra-red heaters.

Abstract: 761,372. Anodizing copper wire. GENERAL ELECTRIC CO. Sept. 18, 1953 [Sept. 20, 1952], No. 25857/53. Class 41. To form a black oxide coating on a copper or copper plated wire or strip, the wire as anode is passed through a series of copper anodizing cells, in the first group of which the potential applied to the cell is not greater than the upper critical value of the anode-electrolyte potential of 0.2 volt for starting oxidation, while in the second and third groups the applied potential is successively greater and increase the thickness of the coating and improve its quality respectively, the coated wire then being washed and dried; and if desired polished. Preferably the voltages applied to individual cells in the second group are equal or are successively only slightly greater while the increased voltage applied in the third group acts on the oxide-coated wire for a shorter period than is occupied by passage of the wire through the first two groups. As shown, a copper wire 5 is fed through a series of cells 6 ... 10 separated by insulating spacers apertured to receive the wire freely and to permit ready flow of an aqueous 15-45 per cent by weight solution of caustic soda or potash, the wire being connected as the anode while the cathode connections are made to the cell containers. For this last purpose stand pipes 16 on each cell for the escape of gases evolved in electrolysis serve as cathode connections and are held at potentials appropriate to the group to which the cells belong so that the wire is subjected over its whole travel to an electrolysing voltage as shown in Fig. 1. The electrolyte is held at a temperature of 80-105‹ C. by circulating it by means of a pump 18 over an external heater 22, a now meter 23 being also provided. Instead of a single wire, two or more parallel wires or an interwoven multistrand wire may be similarly anodized. The oxide-coated wires are suitable for coating with resinous compositions as in Specification 761,373. Specification 760,122 also is referred to.
