Title: Improvements in or relating to insoles for boots, shoes and slippers
IPC: A43B13/39
Filed: 1925-02-04
Abstract: 251,362. Shoe Inventions, Ltd., and Rice, F. E. Feb. 4, 1925. Connecting uppers to insoles; heels; stiffeners; soles.-An insole for boots, shoes, or slippers is split from the heel to the fore part and the layers or plies are inter-attached to form an external part, Fig. 3, for attachment of the sole and upper, narrower in width at the waist than the inner part which supports the arch of the foot. 'The plies are sewn together by stitching D, Fig. 2, forming a pocket into which a metal shank piece E is inserted. The plies are then stuck down at the heel. The edge of the forepart is channelled as usual and the lip turned back along the narrow line of the stitching and trimmed as at F, Fig. 3. A further shank piece H may be attached on this side of the insole corresponding to the first shank piece E by the same rivets. A margin C at the waist of the inner ply may be stiffened with a thermoplastic substance or otherwise to support the arch of the foot. Where a high heel is employed or where heels are removed to be replaced intact, a metal plate slightly smaller, but of the same shape, is inserted between the plies and suitably punched with screw holes.

Title: A method and an apparatus for wet and dry screening
Inventor: HUKKI RISTO TAPANI
IPC: B03B5/56
Filed: 1964-01-24
Abstract: 1,029,001. Wet and dry screening. INSINOORITOIMISTO-ENGINEERING BUREAU R. T. KUKKI. Jan. 24,1964, No. 3185/64. Heading B2H. Material is separated into fine and coarse fractions in a drum screen which is rotated at such a supercritical speed that the outer layer of material next to the inner surface of the screen is caused to move in the same direction as such surface but at a subcritical speed, the resulting speed difference determining the maximum size of particles which can pass through a given screen opening; the fine particles pass through the screen by the combined effect of centrifugal and gravitational forces and the retained particles are discharged separately from the screen. The maximum size of the fines can be selected by choosing the correct screen speed within the speed range between the theoretical critical speed and the speed at which the solids will centrifuge. The material may be fed as a pulp from a hopper 5 and classified by partitions 21, 22 before being directed by an adjustable baffle 7 on to the screen 1 which is driven by a variable speed drive and formed of rubber or chromium plated metal bars of rectangular or V-shaped cross-section; the inside surface of the screen should be sufficiently smooth to give a sliding coefficient of friction of less than 1.0 between the screen and material. Particles progress upwardly and fall, as shown by the arrows in Fig. 1,on to a grooved plate 15 which directs the larger particles, falling on the outer grooves, out of the screening area and into a collecting funnel 19 for the coarse fraction; the fines are returned to the screening zone for re-screening and eventually pass through the screen into a launder 8 which may be adjusted by rods 9 and shaken by a vibrator 11 to direct the fines into a collecting funnel 17. Water is sprayed from pipes 12,13,14 so as to further reduce the sliding friction between the screen and material, re-pulp and wash particles remaining on the screen, to assist removal of the coarse fraction over the rim of the screen and to clean the openings. If desired, the screen may be rotated eccentrically and for improving the discharge, rotated about an inclined axis or be conically formed. For dry separating, the feed is introduced by a vibrating feeder or by pneumatic means; air may be sprayed from the pipes 12,13,14 instead of water and a dust extractor and separator connected to the casing 16.

Filed: 1917-03-08
Abstract: 113,835. Insull, M. J. March 8, 1917. Electrode furnaces.-Tungsten ingots and the like, particularly ingots of compressed tungsten particles, are welded or sintered by heating the ingots held in suspension preferably in a substantially horizontal position to a temperature which may be but little below the melting-point of tungsten and simultaneously subjecting the ingots to a continually longitudinal compressive stress be. tween electrodes whose ends are permanently maintained in parallelism during longitudinal movement of the electrodes. The process may be carried out in an inert atmosphere, such as one of hydrogen, or in a vacuum. Fig. 1 is a vertical section of a water-cooled electric furnace for use in the process, and Fig. 2 is a transverse section. The ingot 56 is held between electrodes 43 and 55, the former of which is clamped in an electrode support 39 by means of a copper plate and screws 45, while the electrode 55 is clamped in a slidable support 52, Fig. 2, fitted within a dove-tailed channel 51 and controlled by a spring. 53; the electrode is held down by a plate and screws 57. The electrode support 39 has a water chamber connected by tubes 41 to water tubes 40 within a metal conductor 35 passing through and insulated from the fixed, end wall 27 of the furnace, and the other electrode support is mounted upon a water. cooled conductor 47 passing through and insulated from the end wall 27. Insulating-blocks 49, 50 connect the conductor 47 to the conductor 35. The electrodes between which the ingot is clamped are preferably of tungsten and are preferably sprinkled with graphite or other form of carbon. The movable part 14 of the furnace is a double shell which can slide on rails 11, 12 towards or away from the fixed end wall 27, to enable the tungsten ingots to be placed in position or removed. Asbestos, rubber, or other sealing material on the movable shell bears against the wall 27, and a tight joint is obtained by forcing down a handle 32 having rollers 31 which press against cam pieces 33 on the furnace. Water flows through the shell 15 from a pipe 20 and is discharged by a pipe 21 and similarly water flows through the end wall 27 from a pipe 28, and is discharged by a pipe 29.

Title: Improvements in the manufacture of cellulose acetate filaments and threads
IPC: D06M11/05
Filed: 1934-02-12
Abstract: <PICT:0438584/IV/1> Continuous filaments of cellulose acetate and threads consisting of such filaments are subjected to a stretching operation in the presence of saturated or wet steam under pressure at a temperature above 100 DEG  C., but not exceeding 120 DEG  C.  The stretching operation may be carried out on the materials during the course of their travel from one point to another, e.g. a number of threads may be stretched simultaneously while running from one creel of bobbins to another.  A suitable apparatus for stretching the materials comprises a steam chamber 4 provided with perforated steam pipes 11 and 12, a pressure gauge 10, relief valve 9, and drain pipe 15. The threads are drawn from a creel of bobbins 2, pass through nip rollers 3, and thence pass into the steam chamber through holes in the end plate 7.  The threads leave the chamber through holes in the opposite end plate 8 and pass through nip rollers 5 which stretch the threads and deliver them to a creel of bobbins 6.  The orifices in the end plates should be sufficiently small to allow the pressure to be maintained.  According to the conditions of stretching, the products may be either such that the individual filamentary character of the threads is preserved, or such that the individual filaments are fused together.  Favourable conditions for avoiding fusion are obtained by causing the steam to impinge upon the materials immediately after their entry into the steam chamber.  The stretched materials may be subjected to any desired after-treatments, e.g. treatments to cause shrinkage as described in Specification 389,823, or partial or substantially complete saponification.  Specifications 177,868, 179,234, 316,521, 318,468, [all in Class 2 (ii)], 340,324, 340,325, 340,436, 340,437, 343,062, 370,430, 402,104, 402,105, 402,106, 403,106; 424,683, 424,752, 424,830, 424,879, [all in Group IX], and 438,656 also are referred to.
