Title: Improvement in the construction of concrete sheet piles
IPC: E02D5/10
Filed: 1921-05-20
Abstract: 180,204. Tetsuka, S., and Naito, F. May 20, 1921. Piles.-Concrete sheet piles are formed by means of preparatory piles having inner and outer tubes, the outer tubes 1 being provided with longitudinal projections 2. These projections may be opposite one another, at right-angles to one another, or simply on one side only, depending on the type of wall to be built. The projections are provided with a ridge 8 and groove 9, so that while the piles are being built the ridge of one pile dovetails into the groove in the next. The inner tube 3 is provided with a conical shoe 4 and driving head 5. After the preparatory piles are driven, the inner tube 3 is first withdrawn and then the outer tube is filled with concrete. This outer tube is next withdrawn, the concrete filling up the spaces left by the projections 1, 2. To prevent water from passing into the space between the outer and inner tube, an external shoe 6 is provided with rubber packing 7.

[Class 44] In a belt and like fastening particularly applicable to parachute harness and of the kind in which a catch member with a projection is inserted between two spring plate members the projection engaging a recess in one under the spring action of the other the catch member, Figs. 2, 4, comprises a plate A with side wings D in which a member C (to which one belt end, not shown, is permanently connected) is pivoted, the leading edge F' being sharply bent back on itself except at the central portion which is left spaced from the plate A to provide the projection F. The co-operating member, Figs. 3, 5, is formed from a spring metal blank to provide superposed plates G, H, plate G having side wings I in which the belt-attachment member C<1> is pivoted. Plate H has a downwardly bent leading edge J leading to a central stamped-out portion K to provide a recess H<1> engaged by projection F. Wings D, I act as guides when plate A is inserted between plates G, H, and entry may be limited by an offset L. Separation is effected by tilting the fastening members relatively, so that plate A separates plate G, H by lever action and disengages the projection from the recess.

Filed: 1956-05-08
Abstract: 824,084. Sewing; sewing machines. UNITED STATES BLIND STITCH MACHINE CORPORATION. May 8, 1956, No. 14297/56. Class 112 The formation of felling stitches S in a blind-stitch sewing machine, between the edge E, Fig. 7, of a comparatively wide upper layer 75 and the comparatively narrow right hand portions of a lower layer 74, or between sleeve lining 81, Fig. 1 (not shown), and the inwardly turned-in portion 82 (Fig. 1, not shown), of a sleeve cuff disposed to the right of the lining, is facilitated by positioning the work-bender R immediately to the right of edge E and by arranging the needle N to swing from right to left in the work-piercing stroke, whereby the greater part of the work is disposed away from the machine, only the single layer 74 and a small part of layer 75, or the portion 82 and a small part of the lining 81 resting on the work support. Layer 75 is doubled in at edge E to form an intermediate layer 75a. The machine comprises a base B to which is pivoted at Ha a work support H, and which supports an arm 1 to which is fixed a frame F carrying the drives for the needle, looper and work feed. The curved needle N is carried by an arm 11 fixed to one end of a shaft 12 journalled in frame F. An arm 60 at the other end of shaft 12 is pivoted on a pin 70 projecting from a ball 69 journalled within an arm 64 extending from the straps 62, 62a of an eccentric 37 carried by the end of a driving shaft 36 in arm 1, to effect oscillation of the needle. The work support H carries a pair of work-supporting ribs 16, and also the work-bending rib R which is fixed to an oscillating shaft 47, rib R projecting upwardly through a plate 14 fixed to frame F. A finger 48 pivoted to plate 14 at 50, is biased downwards by a spring 52 into engagement with the bight formed by rib R. The looper L is formed with a pair of fingers 23, 24 and is secured to one end of a rod 27, the other end of which is fixed to a yoke 31. The latter is pivoted on a pin 34 carried by a sleeve 35 journalled on a pin 36 projecting obliquely from the outer face of eccentric 37. A ball 27a, formed on rod 27, is journalled in an arm 28 which in turn is journalled on a pin 30. The latter is screwed eccentrically into a cylindrical bushing 40 which is turntable in frame F and is fixable in adjusted position by a grub screw. The arrangement provides for moving rod 27 longitudinally between the extreme positions shown in full and broken lines respectively in Fig. 3, while also turning rod 27 about its axis, whereby the looper is moved towards and away from the needle and also across the line of stitching, the degree of the latter movement being regulated by the position of bushing 40. A feeding foot 22, which is disposed in the slot 21, is fixed to one end of a feed bar 42, the other end of which is provided with a strap 42a embracing the eccentric 37. Bar 42 is pivoted intermediately at 45 to a disc 44 which is in turn pivoted at 43 to frame F. Specification 824,085 is referred to.

Adjustment of shed timing relative to beat-up is effected by rotating a worm 28 meshing with a wormwheel rim 27 on a casing 26 carrying planetary pinions 22, 23, which couple a gear 24 on the crankshaft 13 with a gear 21 on a hollow shaft 20 driving the shedding mechanism through gears 12a, 11; when the correct adjustment is obtained, the loom is stopped and a setscrew 33 tightened to lock the gear 12a to the crankshaft directly, thereby relieving the gears 21-24 of driving load. A scale on the casing 26 enables the setting to be read against a fixed pointer. In a simpler arrangement, adjustable only with the loom stopped, a gear loose on the crankshaft carries on its side a worm meshing with a worm wheel fixed on the crankshaft ; a scale on the gear and a pointer on the worm wheel indicate the setting. The mechanism may be situated in a dobby or jacquard instead of on the crankshaft.

Title: Method for Purifying Acetone
IPC: C07C49/08

Abstract: 1,174,298. Purification of acetone. MITSUBISHI CHEMICAL INDUSTRIES Ltd. 29 March, 1967 [30 March, 1966 (2)], No. 14362/67. Heading C2C. A process for the purification of acetone comprises rectifying, in a rectifying column, crude acetone manufactured by the oxidation of propylene in the presence of a catalyst comprising a solution containing a salt of a metal of the platinum group and a chloride of a heavy metal having at least two valencies, and from which by-products of lower boiling point have been removed, which includes withdrawing a sidestream comprising chlorine-containing by-products from an intermediate part of the rectifying column, mixing the sidestream with water, separating the resulting mixture into an aqueous phase and an organic phase, and passing the aqueous phase back to the rectifying column or to a purifying step which precedes that effected in the rectifying column. The byproducts of lower boiling point may be removed in a column by extractive distillation with water and the said aqueous phase may be recycled to that extractive distillation column. The water is suitably added to the side stream at a temperature of 5-60‹ C. and in an amount of 0À2-3À0 times the volume of the side stream. The acetone vapour may be further treated with an aqueous alkaline solution in the upper part of the rectification column, and higher boiling by-products may be collected at the bottom of the rectification column. A suitable apparatus for carrying out the above process is described. Reference has been directed by the Comptroller to Specification 1,060,742.

Patent GB-146018-A (GB)
Abstract: 146,018. Vignery, A. Oct. 7, 1919. Pumps in series; regulating delivery by secondary piston reciprocating in pump barrel; suction reservoirs; valves, arrangement of.-A lubricating pump comprises two pump barrels arranged side by side in series, and open at each end. Each barrel has two pistons a, b of which the former is reciprocated by an eccentric and lever g, while the latter is moved inwards partly by a camactuated lever k and partly by the suction in the barrel. The movement of the piston b is limited by an adjustable stop m. During the delivery stroke of the piston a the piston b is returned against the stop k by the liquid pressure, and the liquid is delivered through a port e and pipe o to the suction side of the second barrel. By adjusting the stop m the volume of liquid drawn in to the barrel is varied. Several pumps may be mounted in the same receptacle and actuated by a common mechanism.
