Title: Pneumatic nailing device
IPC: B25C1/04
Filed: 1959-09-09
Abstract: 891,502. Nailing machines. REICH, K. Sept. 9, 1959 [Dec. 24, 1958], No. 30762/59. Class 89(3) A pneumatic nailing machine comprises a cylinder 4, Fig. 1, a driver 10 slidable therein, a nozzle 38 containing a driving channel 39, a feed conduit 42 for nails or like fasteners ending in a portion 44 entering channel 39 through a lateral slot 45 and being movable thereoutof before the driver starts its stroke. A source of compressed air is connected to inlet 18 and enters a chamber 9 concentric with cylinder 4. A further concentric chamber 8 receives the air beneath the driver compressed during its stroke to return the driver to its raised position where it is held by plungers 12. When trigger 34, Fig. 2, is pivoted clockwise, valve 36 is closed and valve 31 opened to apply pressure air to raise piston 19 closing exhaust aperture 20 and opening valve 17. Thus air is applied above the driver from chamber 9 and the driver drives a nail 40 held in jaws 97. When the trigger is released the pressure in inlet 18 moves a piston 46 to restore the trigger. In this arrangement, the portion 44 is connected to the trigger to pivot therewith about pin 33. The nail-feeding mechanism consists of a hopper 50, Fig. 4, connected to conduit 42 via a valve 86, and nails are dropped individually into the hopper by a rod 54 which is reciprocated by a piston 53 to pick-up a nail in a recess 57 from guide rails 55 and release it into the hopper. Chamber 64 behind piston 53 is connected via conduit 63 to a valve 60 comprising a ball 67 controlling the supply of air from chamber 9 to a passage 62 and conduit 63. The ball is raised off its seat by a tappet 68<SP>1</SP> moved by the driver during its stroke. Passage 62 is vented to atmosphere, when the trigger is released, by a plunger 46<SP>1</SP> on piston 46. Thus, when the driver makes its stroke, valve 60 is opened and piston 53 moves to the left, and when the trigger is released, the piston is returned by a spring 69 to drop a nail in the hopper, and moves, on a pivoted pawl 71, a bell crank 74 to open valve 80 and admit compressed air from a conduit 82 to move valve 86 to the left, and admit a blast of air via line 91 to conduit 42 to move a nail therealong. As piston 53 is returned, the pawl slips off lever 74 and valves 80, 86 are restored to their original positions. In another arrangement, the nozzle 38 is slidable into the cylinder against a spring and has one or more oblique end faces engaged by rollers on portion 44 which pivots out of the drive-channel as the nozzle moves in. Portion 44 moves the equivalent of trigger 34 which may be within the machine. In a modification, the sliding nozzle 306, Fig. 8, moves a lever 308, 309, 310, pivoted at 307, against a spring 313, to remove a stop 314 and permit trigger 305 to pivot portion 44 out of the drive channel.
Patent GB-882536-A (GB)
Title: Improvements in or relating to treatment of gases
IPC: C10K3/04
Filed: 1959-09-09
Abstract: CO in a gas containing H2, N2, CO2 and CO, e.g. ammonia synthesis gas, is preferentially oxidized to CO2 by adding water vapour and sufficient air or other free O2-containing gas to provide an O2 to CO volume ratio 3:1 to 0,25:1 and passing the resulting gas mixture over a supported platinum catalyst at elevated temperature.  The catalyst may be 0,01-5% Pt on alumina, silica, kieselguhr, silica gel, or diatomaceous earth and may operate at 60 DEG -1200 DEG F., preferably 200 DEG -450 DEG F. with a gas velocity of 100-25,000 cu. ft. p gas/hr./cu. ft. catalyst at a pressure atmospheric-300 p.s.i.g. A single stage catalyst unit may be used and CO2 removed by scrubbing with monoethanolamine.  Methane is also oxidized to CO2 and H2 and excess O2 combine to form H2O.  Alternatively, a two stage catalyst treatment may be used with intermediate and final removal of CO2 and air or other free O2-containing gas being added to provide the required O2 to CO2 volume ratio before each stage. The gas resulting from the single stage unit may also be passed to a methanator where CO and CO2 react with H2 at 600 DEG  F. to form methane and water. The gas before catalyst treatment may be partially, or completely, saturated with water vapour which may be added before or after the addition of air.  Water vapour is removed by cooling the gas before CO2 removal after the catalyst contact and between two contacts.  The gas after CO2 removal is passed direct to ammonia synthesis, and heat is conserved by provision of heat exchange units in the gas flow system.  Where a two-stage system is used the gas velocity in the second stage may be 100-30,000 cu. ft./hr./cu. ft. catalyst.  The catalyst may be reactivated by contact with hot air, e.g. at 250 DEG F.  A reactor containing a plurality of fixed catalyst beds, all but one equipped with cooling tube bundles, is described.

Title: Improvements in filters or strainers
IPC: B01D29/00
Filed: 1922-11-10
Abstract: 211,199. Zwicky, J. Nov. 10, 1922. Filters having sheet filtering-materials.-A substantially cylindrical filtering element, composed of one or more layers of wire gauze or other filtering-medium on a skeleton frame, makes joint with the filter casing along a surface parallel to the direction in which the element is removed and of the full diameter of the straining- member, said joint being independent of the butt joint around the opening in the casing through which the element is removed. The element and casing are so formed as to provide a recess in which solid matter separated by the filter can collect. In the arrangement shown in Figs. 1 and 2 the frame comprises longitudinal bars 8 and a cap 7, the other end 9 being closed or formed as a spider. The frame of the element makes joint with reduced ends or internal flanges 5, 6 of the casing. The filtering gauze is not completely cylindrical, a space being left between the two lower bars 8, which make joint with the edges of the inlet opening 11, through which the liquid can pass to the interior of the element. It filters outward through the element and any material separated tends to fall into the recesses of the V-shaped bars 8. If the filter is intended for use with the element vertical the end of the frame is made solid to the line 17, a recess being thus formed in which grit can collect. Fig. 4 shows an arrangement in which the inlet and outlet flanges are at right angles. The lower end of the element is provided with a cylindrical partition or trap 21 to which a non-return valve 22, held on its seat by a spring 23, may be fitted. The partition forms a space for the collection of separated matter. In a. similar arrangement the lower end of the frame is made conical or spherical to engage a corresponding portion of the interior of the casing, and the cap to close the opening at the top is separate, a spring being interposed between the cap and the frame.

Title: A process for the separation of sugar from molasses
IPC: C13B35/06
Filed: 1945-11-16
Abstract: Sugar is separated by passing molasses through an organolite, charged with H-ions and obtained by treating coal with strong sulphuric acid, oleum or sulphur trioxide, and neutralizing and concentrating the resultant liquid, not more than two parts of molasses (calculated as solid matter) being used to one part of organolite.  In an example, a percolator is filled with an organolite, prepared by exposing pit coal to sulphur trioxide-containing roast gases of a sulphuric acid plant for 2 hours, and normal beet molasses passed through at room temperature in a proportion of one to one parts by weight on dry substances. The percolate is neutralized with milk of lime to pH 7 and then evaporated and boiled to sugar.  The organolite is rinsed with water and regenerated with 5 per cent sulphuric acid and again washed with water.

Title: Etching plate movement mechanism
IPC: B44B3/00
Filed: 1956-10-11
Abstract: 800,897. Etching. DOW CHEMICAL CO. Oct. 11, 1956 [Nov. 21, 1955], No. 31065/56. Class 100(2) In a splash-type etching machine, a plate to be etched is mounted on a holder carried on a shaft extending upwardly through an elongated slot in a mounting plate and journalled to a carriage which is reciprocated, the shaft carrying coupling means which is rotated on reciprocation of the carriage by means of a closed loop driving means such as a chain, one part of which is held stationary for most of the time so that reciprocation of the carriage moves the coupling along the loop to rotate it, while the loop is advanced intermittently in one direction so as to vary the relationship between the angular and linear positions of the plate, the loop being held stationary between such advancing movements. The plate to be etched is carried on a holder on the lower end of a shaft 40 projecting down through a slot 38 in the cover 12 of the etching bath and mounted at its upper end in a carriage plate 14 having an extension 50. The carriage plate 14 is reciprocated on rods 18 by hydraulic mechanism 30 through a rod 26, controlled by limit and reversal switches 82, 84 operated by a contactor 86 on the carriage plate. A chain 48 passes round a sprocket 46 on the shaft 40, a sprocket 54 on the extension 50, and sprockets 60, 62 on shafts 64, 66 journalled in the cover 12. The shaft 64 carries a ratchet wheel 70 engaged by a pawl 74 on an arm 72 pivoted to an arm 80 pivoted to the plate 14. The arm 72 is apertured to fit over the shaft 64. On each leftward stroke of the plate 14, the ratchet is moved one tooth to index the chain 48 forwards. Apart from the indexing action, the chain 48 is held stationary where it contacts the sprocket 60 by friction between the ratchet 70, the arm 72, a compression spring, and a stop member 88 on the shaft 64. Reciprocation of the carriage thus causes the chain to rotate the shaft 40 and the plate holder, while the indexing of the chain causes progression of the angular position of the plate holder with respect to its linear position. Instead of the hydraulic mechanism, an electric motor on the plate 14 could be geared to racks on the rods 18. In another form, the chain passes over the sprocket 46 and only two other sprockets, on shafts journalled in the cover 12 on opposite sides of the plate, 14, one of said shafts carrying the ratchet mechanism. Specification 725,110 is referred to.
