Riders and their appurtenances.-A balance for use in determining specific gravity, and of the kind in which a sinker of known weight is counterpoised in the liquid of which the specific gravity is to be determined, is provided with a weighing-chain hung at one end of the beam and attached to a slider adjustable up and down a graduated scale as described in Specification 100,737. The sinker G, which may be in the form of a thermometer, is suspended from one end of the beam, which is grooved on 'both sides and carries a rider L provided with projections which engage the groove and also a projection i, Fig. 3, which engages notches h in the beam to indicate definite specific gravities. At the other end of the beam is hung a chain 1 the free end of which is attached to a slider J having a vernier thereon and moved over a scale K by means of a screw p as described in the said prior Specification. The scale is so graduated that, when the apparatus is balanced, the reading added to that of the rider L gives the specific gravity. In order to adjust the apparatus, a weight s is provided which exactly balances the sinker G in air; this is hung on the hook r and the screw u adjusted until the apparatus is balanced.

Patent GB-762151-A (GB)
Title: Improvements in or relating to process of sweetening sour hydrocarbon oils
IPC: F02B47/00
Filed: 1954-07-29
Abstract: A doctor sweetening process comprises contacting a hydrocarbon oil with doctor solution, in the presence of free sulphur in an amount in excess of the theoretical amount needed to convert mercaptans in the oil to disulphides, and free oxygen in an amount sufficient to oxidize the PbS formed in the sweetening reaction, at a temperature of 140-200 DEG F.  The process is continued until all the PbS has been converted to soluble plumbite, and doctor-sweet oil is then separated from the solution.  The oxygen may be present as free oxygen or air or as a compound, such as hydrogen peroxide or potassium permanganate, which readily dissociates to produce free oxygen.  The sulphur may be added as a solution in xylene.  The doctor solution may contain 5-30 wt. per cent of free alkali metal hydroxide and 1.5-2.5 per cent PbO based on the aqueous alkali solution.  The oil may first be washed with aqueous caustic alkali solution to remove H2.S.  The sweet oil may be washed with water or passed through a coalescer, e.g. filter-paper, glass wool, crushed rock or sand.  Distillates boiling below 750 DEG F., e.g. naphtha, kerosene, diesel oil, heater oil and gas oil, and distillates obtained from thermal and catalytic cracking and reforming processes, may be treated.

Title: Improvements in blast gobbing machines and the like having a two-compartment oscillating closure
IPC: E21F15/10
Filed: 1949-08-26
Abstract: 659,030. Pneumatic conveyers. BRIEDEN, K., and KUHME, E., (trading as MASCHINENFABRIK K. BRIEDEN & CO. K. G.), OELLRICH, A., (trading as MASCHINENFABRIK UND EISINGIESEREI, A. BEIEN), and HEIDEMANN, A. Aug. 26, 1949, No. 22212. [Class 78 (i)] In a machine having a two compartment rotary member for feeding material into a pipe containing fluid under pressure, in particular a blast gobbing machine, the rotary member is oscillated by means of a rack through a double piston engine. The material charged into a hopper 3 is fed into a compressed air pipe 4 by means of a rotary member 2 which forms two compartments with the chamber 1. The member 2 connects with a shaft 13 having a pinion 12 fixed thereon. A double piston engine 7 in a housing 8 has pistons 9 and 10 connected by a rack 11 which engages the pinion 12. The slide control 16 consists of a slide piston 17 arranged to connect with the compressed air supply pipes 14 and 15. Regulation of the piston 17 is effected automatically by the piston engine with the aid of a reversing piston 18 operated by the pistons 9 and 10 so that the slide piston is alternately actuated through one or other of the pipes 19 and moved to its regulating position. A handle 20 is provided on the piston 18 for hand operation of the reversing piston. To compensate for wear on the slide 2 a hand-wheel 5 is provided to displace the slide axially and the housings of the double piston engine and the control are formed as a single unit secured to the housing of the oscillating slide.

Title: Machine for spinning synthetic filament yarns
IPC: D01D5/04
Filed: 1972-05-12
Abstract: 1386309 Synthetic filaments NEUMUNSTERSCHE MASCHINENUND APPARATEBAU GmbH 12 May 1972 [14 May 1971] 22511/72 Heading B5B A machine for spinning synthetic filament yarns comprises at least one row of vertical spinning ducts, each duct being adapted to spin a plurality of filaments and issue them in a plane common to each of the ducts of a respective row, and a winding assembly for each spinning duct for winding on the filaments from that duct individually, each winding assembly having a plurality of winding spindles mounted in a respective row extending substantially perpendicularly to the plane so that the spindles are progressively spaced from the plane and disposed within a spacing defined by the spacing between its respective duct and an adjacent duct. As shown, a group of eight filaments 35 from a spinning duct (not shown) are guided past preparation rollers 3 and 4 on a machine mounting frame 1 to take-off rollers 5 and 6, and then travel over preheating godets 7 and 8, and past stretching pins 9 in the stretching zone, to arrive at fixing godets 10 and 11. Casing 12, sealed by a labyrinth seal 13, prevents heat losses. The filaments are then guided over a finishing unit 14, having adjustable guide bars 15 and 16, to the guide rollers 17 to 20, which are vertically staggered so that the filaments travelling to the more remote guide rollers avoid contact with the nearer rollers. From each of the guide rollers, two filaments are guided to the winding units 22 to 29 which are in the form of pivotal bobbin holders. In each winding unit, two bobbins 30 and 31 pivot about a point 32 so that driving roller 33 which, with increasing package diameter, is deflected in the direction of the arrow, drives the particular bobbin which is in operation, the filament being guided through a traversing mechanism 34. The use of pivotal bobbin holders enables packages to be automatically changed. Figs. 3 and 4 (not reproduced) show layouts of the winding assemblies in relation to the spinning ducts.

Abstract: 837,437. Making paper &c. bags; cartons. FLAX, V. July 20, 1956, No. 22523/56. Classes 18 and 94(2). A flattened tubular web 1 of flexible material with inwardly-extending bellows folds 4, 5 is transversely sealed at spaced intervals 8 and cut through the seals and midway between them to form separate bags. The weight of the filling assisted if necessary by gas pressure causes the bottom to assume a block form 10. The open top 11 is then folded and sealed. The fold lines for the top and bottom may be impressed on the web 1, or lining portions may be provided over the areas bordering the fold lines to facilitate the folding. Alternatively a thread, wire cord or strip may be bonded to the web along the fold lines. The web may be of cardboard scored at the fold lines. Fig. 7, shows a modified bottom fold in which the sealed part 8<SP>1</SP> is made longer and folded to bring the cut edge into register with the lower edge 8<SP>11</SP> of the container. The ends may be mainained flat by means of a label. The faces 2, 3 at the open end may be bonded to the adjacent surface of one of the bellows side portions to facilitate folding.

Abstract: 794,362. Valves. THOMPSON BROS. (BILSTON), Ltd., and HUTCHESON, A. M. July 30, 1956 [Aug. 10, 1955], No. 22991/55. Class 135. A tank has valve means responsive to small differences in internal and external pressures for venting and auxiliary valve means which automatically closes to prevent spillage when the tank falls to either side. A tank 11 has a valve housing 10 containing flexible diaphragm one-way inlet 16 and outlet 17 valves to normally sustain substantial balance between the interior of the tank and external atmosphere. Two ports 12, 13 normally provide communication between the housing 10 and tank 11 through hollow valves 18, 19. The valves 18, 19 have confronting annular seatings 26, 27 co-operating with seating rings 28, and are geared for motion in opposed directions by racks 20, 21 and a pinion 22 fast on the shaft 23 of a pair of pendulous weights 25. When the tank falls to either side, the weights 25 cause the valves 18, 19 to close by virtue of one seating 26 and one seating 27 engaging the seatings 28, thus preventing the escape of liquid. The seatings 26 are of larger diameter than the seatings 27 such that a pressure rise above a predetermined limit within the tank, causes the valves 18, 19 to open against the action of the weights 25 to vent the tank.
