IPC: A43B3/30
Filed: 1947-01-22
Abstract: 621,409. Measuring and fitting footwear. GARDNER, H. S. Jan. 22, 1947, No. 2063. Convention date, Jan. 31, 1946. [Class 17 (iii)] A visible indication is made on the toes of a foo inserted in footwear, 10 especially for children when the toes extend for wards into a portion of the shoe where continued wear may result in foot deforma tion. The indication may result from one spot 14 of marking substance placed to mark the big toe on the inside of the shoe on the insole or the lining or one spot may be provided, as shown, for each toe, or the whole of the danger area may be treated to give a visible mark. The marking substance, which may be recessed into the sole or applied on the surface, may be of chalk, substances used in backing duplicating paper or releasable dye substances. A safety area extending forward to the edge of the danger area may be treated to give an indication of a different colour, e.g. green instead of red for the danger area.

The polyurethane is prepared suitably by reacting a polyester based on phthalic acid with 1,6-hexane-diisocyanate, a glycol and optionally a polyol containing more than two hydroxyl groups in the presence of a solvent followed by isolation of the polyurethane by known methods. Preferred synthetic resins with which the polyurethanes may be mixed are (1) acrylic resins which may have been reacted with methoxymethylisocyanate, (2) polyesters which contain free hydroxyl groups optionally in combination with melamine resins or blocked polyisocyanates and which may have been reacted with methoxymethylisocyanate and (3) epoxy resins, especially those of epoxide equivalent weight 900 to 1100. The polyurethane is mixed with the synthetic resin and optionally a pigment, the mixture being homogenized by melting in an extruder followed by cooling of melt and granulation of the product.

Abstract: 432,123. Purifying water. SCHNEIDER, A., 28, Gymnasiumstrasse, and GAISSER, F., 65B, 111, Seidenstrasse, both in Stuttgart, Germany. Jan. 22, 1934, No. 2221. Convention date, Jan. 21, 1933. [Class 46] In the purification of water, such as boiler feed water, by freeing it from hardness formers, the raw water is heated to about 100‹ C., and is caused to trickle down in fine distribution in a cylindrical vessel into which a gas consisting chiefly of carburetted hydrogen or nitrogen, or a mixture of both, is introduced in counter current from below, ammonia being previously added to the water or the gas. In the apparatus shown, the raw water enters the steam-jacketted vessel A through a sprinkler a and trickles over granulated iron ore, iron filings or porcelain rings c supported on perforated plates. The nitrogen &c., laden with ammonia is supplied from a vessel C through a pipe d. The treated water leaves through the pipe e and the gas charged with oxygen and excess ammonia passes through a condenser D which separates the ammonia and returns it to the vessel C. The gas then passes through a system E containing heated copper, alkaline pyrogallol, or sodium hydrosulphite to remove the free oxygen and finally enters one or other of the gasometers G, F. While one gasometer is being filled the other discharges into the vessel C, the positions being reversed by the cock m. The water in the vessel A may be heated by waste gases internally and the ammonia may be added directly to the raw water.

[Also in Group XXXVI] In order to grade the voltage distribution between the arc-horns 30, 44, of a circuitbreaker similar to that of Specification 630,838, the arc-chute has a layer or layers of conducting or semi-conducting material provided in or on the wall of the chute. A layer 56 of high resistance paint (see Group XXXVI) is applied on the inside surface of the arc chute, the opposite ends of the layer being connected to the arc horns through the arc horn fixing screws 58. The backs of end liners 57 also have a layer 57a of the paint in contact with the heads of screws 58, and connected to layer 56 by springs 60. The resistance between the arc horns is preferably within the range of 100 megohms to 10,000 megohms. A further layer 51 is coated on the outside of the chute, this layer being connected to the blow-out magnet poles 38, 39 so as to short out the air void between the chute and the poles, and thereby increase the resistance to corona. The layer 51 is covered with a protective coat of varnish. The Specification as open to inspection under Sect. 91 comprises also a modification, in which layers of tin foil are included in the housing of the chute, as it is formed, the outside paint layer 51 and an internal layer at each end being provided. Alternatively, the internal and external layers may be of tin foil also. In a further modification the coil and yoke assembly is coated by dipping or spraying. In this case the chute is only coated at the end nearest the horn 44. This subject-matter does not appear in the Specification as accepted.

Patent GB-820735-A (GB)
Title: Process and plant for extracting liquid from fibrous material
IPC: C13B10/04
Filed: 1956-01-26
Abstract: Liquid is extracted from fibrous material, particularly sugar juice from cane, by squeezing or pressing in at least two consecutive stages, the number of squeezings or pressings to which the material is subjected in the first stage being smaller than that in the second stage or subsequent stages, and the squeezing pressure used during the first stage being larger than that used during the second or subsequent stages.  As applied to sugar cane, the cane is pressed in a first stage with a small number of mills, e.g. from one to three, and is then squeezed in a second, or subsequent, stages at considerably less pressure and with a larger number of mills, e.g. from four to ten, the latter squeezing being accompanied by washing with water and/or part or all of the expressed solution from the second or subsequent stages, e.g. in counterflow.  Crude sugar is extracted from a mixture of solutions extracted from the first and second stages, solution expressed from any subsequent stage being fed back to the second stage.  In the form of invention schematically illustrated, the cane is squeezed after washing during the second stage to reduce its water content.

[Classes 83 (ii) and 83 (iv)] Angular bending; drawing.-An apparatus for flanging sheet metal plates, strips, &c., comprises one or a pair of plate or like clamping members of a shape corresponding to that of the finished article, a number of roller and/or die-carrying frames linked or similarly connected together to take up positions corresponding with the shape of the clamps, an abutment for the frames and means for moving the clamps and work through the frames to cause the rollers or dies to act progressively on the work. The abutment member comprises a removable head d mounted on guides on a bed c and secured thereon by bolts g, and provided with bearings h for a motor driven spindle b, which is provided with sleeves connected thereto and to one or more peg-tooth gear-wheels k by dog clutches m. Arranged opposite the wheel k is a screwadjusted roller n. A shaped flat strip r to be flanged is clamped along the central portion of its width between a pair of correspondingly shaped plates s, t, of which the plate s has a series of holes u to engage the teeth on the wheel k to traverse the work. Secured to the abutment are a series of frames v, each carrying flanging rolls w and/or dies x, the first and second frame being mounted on opposite sides of the abutment to which they are connected by links 21 and ball and socket joints 22. The remaining frames are mounted on the trailing side and are interconnected by links y at the top and bottom of each frame so as to take up a position at right angles to the track of the clamps and work as they pass through the frames. If desired, all the frames may be arranged at the same side of the abutment so that the work may be drawn or pushed through the dies &c. In another form for work in a vertical plane, the work is fed in between a pair of guides 23, Fig. 10, on the leading side of the abutment by a single clamping member s formed with two sets of holes to engage the toothed wheels and with a rib 24 on its underside to form a central groove along the work. Friction between the rib 24 and work r causes feed of the work and a second clamping member may thus be dispensed with. The frames v are all arranged on the trailing 'side of the abutment and are clamped near their sides by a pair of steel strips 25 instead of being linked together.
