Abstract: 255,898. Boston Wire Stitcher Co., (Assignees of Maynard, A. H.). July 25, 1925, [Convention date]. Nailing and stapiing, hand tools for.-Relates to hammer-like stapling machines or tackers having a magazine for holding the staples or other fasteners within its handle, means for automatically feeding the staples or fasteners therefrom to a setting device, and a driver operated when a blow is struck with the head of the hammer to drive the staples or fasteners into the work, and consists in fastener retaining means adapted to engage the foremost fastened and to co-operate with the feeding means to hold the fastener frictionally in driving position beneath the driver. A stapling machine is shown, comprising a hollow handle 2 with a weight 3 at one end and a core 12 over which staples s are carried, the core being pivoted at 20 at the other end of the handle. The staples are retained in position by a channel-shaped member 14 and are led forward by a pusher 42 secured to a traveller 36 normally pressed forwardly by a spring 30, preferably of rectangular section. The foremost staple is clear of the core and is pressed against a gate 50. In line with this staple is a driving blade 55 which passes over a rivet 57 and engages a groove 56 both in the weight 3. Normally, the weight 3 and core 12 are pressed apart by a spring 60, but on a. blow being struck with the tool the momentum of the weight 3 compresses the spring and the blade 55 drives the foremost staple into the work, the next staple being fed into position automatically as the spring 60 expands. To charge the magazine, a spring plunger 70 is depressed until narrow portions of it coincide with slots 54 in the side members of the gate 50, when this can be turned about its pivot 62 to expose the end of the core 12. The traveller 36 is then retracted by a finger-piece 41 until the forward end of the pusher 42 engages a notch 45 in the core, a slot being provided in the under side of the handle 2 to allow the travel of the finger piece. The rear end of the core is provided with a releasable pivot, the pin 20 having two peripheral grooves into one of which an edge of a member 25 of L-section is normally pressed by the spring 30. On pressing the exposed end of the latch the pivot 20 may be withdrawn. The pivot 62 is similarly made. the spring 60 being utilized to press the edges of holes in a channel member into grooves in the pivot.

Abstract: 280,165. Koppers Co., (Assignees of Jacobson, D. L., and Gollmar, H. A.). Nov. 5, 1926, [Convention datel. Materials and compositions for purifying.-In a process for removing hydrogen sulphide and other acidic impurities such as hydrogen cyanide from fuel or other gases in which the gas is washed in an alkaline liquid containing a metal compound, the sulphided liquid being regenerated by means of air or oxygen to recover sulphur, the wash liquid comprises a solution of a compound of arsenic antimony or tin, or of molybdenum, vanadium, tungsten, germanium, uranium, iridium, bismuth, mercury, rhodium, indium, gold, or platinum, the sulphides of these metals being soluble in an alkaline sulphide solution. The solution may be prepared by sulphiding a solution of sodium arsenite as by passing through it a gas laden with hydrogen sulphide and subjecting the solution to aeration, no sulphur or hydrogen being liberated during this stage. The resulting thio-arsenic compound in solution is then repeatedly used to absorb hydrogen sulphide and successively regenerated by oxidation to liberate free sulphur. A ratio of at least three atoms of sodium to one of arsenic is maintained in the sodium arsenite solution and the thio-arsenic compound is preferably maintained slightly alkaline. The amount of arsenic may vary from 0.1 to 0.8 per cent As2O3 and the temperature of the solution especially during the regeneration stage is preferably maintained at about 30<0> C. or between 20‹ and 50‹ C. Oxidizing agents such as oxygen or hydrogen peroxide may be used for regenerating the sulphided liquid but mechanical agitators which aerate the solution and effect a flotation of the sulphur are preferably employed. Bases such as potassium, ammonium, magnesium or calcium may be substituted for sodium. The treatment may be applied to waste gases or air such as the " actifier air " of the sodium carbonate liquid purification process.

IPC: F27B7/20
Filed: 1925-07-24
Abstract: 261,814. Rigby, T. July 24, 1925. Rotary furnaces; changing. - In the manufacture of cement by the wet method in rotary kilns, the slurry is sprayed into and is caused to fill a substantial portion of the kiln, the drying being so controlled that the deposited material though still moist is no longer sufficiently moist to agglomerate in large masses. The deposited material should contain at least 10 per cent of moisture, but should have lost at least 20 per cent of its original moisture content. The spraying devices should be so situated that the axes of the sprays coincide with that of the kiln at the points at which the sprays attain their maximum diameter, which should correspond with that of the kiln. One or more sprays may be used, and in the latter case they may project the slurry either to the same part of the kiln or into different parts as shown in Fig. 1. The spraying devices 10 may be situated either inside or outside the kiln but are preferably mounted in a chamber 3 situated in the rear of the kiln head 5 and capable of being projected forwards into the kiln head, or if the latter be narrow the sprays may be mounted in a rearward extension of it. Scrapers 12, 15 may be fitted to clear the chamber 3 and the kiln mouth respectively of deposited material, and the base of the kiln head contains slurry or other liquid which catches any material removed by the scrapers or carried away by the kiln gases. If the interior of the kiln is provided with the customary slurry agitating devices such as chains or fins these should not extend upwards into the zone where the slurry is deposited, and the brick lining may also be omitted from this zone. Specifications 22734/02 and 243,410 are referred to.

Abstract: 804,352. Mechanical presses. GOLDING, W. F. July 2, 1956 [June 30, 1955]. No. 18990/55. Class 87(2). [Also in Group XXIX] The movable platen 15 of an upstroking press is actuated through toggles 12 by a hydraulic ram 10. The ram is formed with an extension 17 sliding in a bore 18 in the platen 15. When the platen is at the end of its working stroke and not subject to load, there is a clearance between the end of the extension 17 and the end of the bore equal to the maximum permissible deflection of the platen. In operation, should there be overload due to the work between the platens, the maximum deflection is exceeded and the platen presses on the extension 17, thus increasing the pressure in the ram cylinder, thereby opening an overload valve and initiating a return stroke. The gap between the fixed and movable platens 1, 15 can be adjusted by raising or lowering (through screw-and-nut and worm gearing) a base 4 on which the ram and the toggle mechanism are mounted.
