Abstract: 528,185. SteeL ELLIS, L. S. E. (United States Steel Corporation). April 13, 1939, No. 11240. [Class 72] In the production of steel, pig iron containing more than 5.00 per cent. of manganese and more than 0.7 of phosphorus is produced in a blast furnace by adding sufficient phosphorous- and manganese - containing slag materials to the charge, is then blown in an acid converter with a basic oxidizing slag, the slag separated from the metal and the lather treated in a basic open hearth furnace with a basic oxidizing slag.

A block having a channel 11, Fig. 2, across its width which forms a rain water gutter when assembled side by side with similar blocks has a recess 13 at one side face 12 adjacent channel 11 and a projection 15 at the other side face arranged so that the projection 15 on one block fits into the recess 13 of an adjacent block. As shown the recess 13 is an enlargement of the channel 11 and the projection 15 forms part of a hollow cylinder whose wall is thinner than the plane surface 13b of the recess and whose length is less than the cylindrical surface 13a thereof so that when two blocks are placed side by side there is an annular clearance around the cylindrical surface of projection 15 and a clearance also at its end which is filled with waterproof mastic which preferably does not set hard. The blocks are cemented on their side faces, recesses 16, on each side face forming a key. Some of the blocks are provided with a hole 17, Fig. 3, leading from channel 11 into a recess 18 which is undercut at 19 to receive an asbestos or iron rain water pipe 20. The blocks which are made of concrete may be reinforced by rods 10. In a modification Fig. 7, the projection 15 is increased in length so that on placing two blocks side by side there is a gap between the two side faces which is filled with mortar. There is no keying recess provided but on each side face half-round grooves 22, which are left free of mortar, conduct away any moisture penetrating through a joint. Throatings 24 are provided on the sloping undersurface of the block. Some of the reinforcing rods 10 have upwardly directed loops and the blocks which are assembled above a window have metal bars 27 pushed through the loops so that a concrete lintel 28 may be cast in situ. The blocks are assembled with waterproof mastic 30 and cement 29. A further form of block may have a hole leading from the channel to allow the insertion of a metal sleeve having a horizontal flange at the tip, a recess in the channel receiving the flange, and the sleeve is of such a diameter as to fit inside a standard rain water pipe. Blocks may be provided for internal and external angles and may have a stopped end to the channel.

[Class 83 (iii).] In milling-cutters, boring-heads, planing or turning tools &c. having inserted cutters, each cutter is secured in a slot in a body by wedge action, the cutter being made of a hard material such as that known under the registered Trade Mark " Stellite " and the wedge of a softer material which is capable of being machined readily to receive the formations by which cutter is adjusted in the body. As applied to a milling-cutter, the body 1 has slots 2 for receiving cutters 3 and wedges 4, the wedges being serrated at 7 for engagement with serrations 8 in the slots. Two ribs 9, 10 are provided on each wedge for engagement selectively with grooves 11, 12 on the cutters, thus providing for adjustment of the cutters in two perpendicular directions relatively to the wedges. A further finer adjustment is provided by the serrations on the wedges, and a still finer adjustment may be effected by spacing the serrations in the slots slightly further from the axis of the tool in successive slots so that movement of a cutter and wedge from one slot to the next will displace the cutter outwardly by a distance less than the pitch of the serrations. In a lathe &c. tool the wedge and cutter 25 are secured in a slot of a shank 23, the shank being mounted in its holder so that the securing bolts press on the face 24 to restrain any tendency of the slot to open. Specifications 281,957, [Class 83 (iii), Metals, Cutting], and 386,324 are referred to.

Filed: 1957-04-10
Abstract: 818,651. Carding engines. SCHIAPARELLI, G. April 10, 1957, No. 11652/57. Class 120(1) In a roller carding engine, fibres are opened and carded or drawn during their passage from each slow running worker roller W to the corresponding faster running stripper roller 5 by the action of a small roller A located in contact with and in the angle between rollers W, S, roller A rotating in the opposite direction to that of rollers W. S, at a surface speed greater than that of roller W but less than that of roller S. Fibres carried by a worker W are laid down on the roller, with their free ends pointing forwards, by flaps b of a rapidly-rotating roller L. These fibres pass beneath roller A until their free ends are caught by the stripper while the worker still retains their other ends. As the fibres pass from the worker to the stripper they are subjected to a drafting action. Roller A may be card clothed so as to comb the fibres during drafting. Roller L may be replaced by a smooth or grooved roller. Alternatively, roller L may be dispensed with and roller A may be smoothsurfaced; in that case roller A exerts a frictional control on the fibres during drafting between the worker and stripper. The speeds of rollers A and S may be variable.

In photographs of nuclear particle tracks obtained in a bubble chamber (Fig. 3) the unwanted tracks 22 are eliminated, leaving only the tracks and markings 24 which are required Fig. 5 (not shown). Initially the negative 10 is mounted in the projector of Fig. 1 (not shown), light from a source 12 passing through a condenser 14 to throw an image of the negative, by means of a projection lens 16, on to a blank white sheet mounted on a support 20. The image thus produced is that of Fig. 3. The tracks which are required are then emphasized by an operator using a brush and dark ink. The image now appears as in Fig. 4 (not shown). A light-sensitive copy film 26 is now placed in contact with negative 10, and the condenser 14 is replaced by another condenser 30 of longer focal length. A further exposure by light source 12 will now act on film 26 in all places except those corresponding to all the tracks shown on Fig. 3. At the same time, the sheet on support 20 is illuminated by further lamps 28, 28', the image thereon being thrown by reflected light back on to film 26. In this case the image consists only of the emphasized lines, so that if the two images on film 26 are in correct register, the film will be exposed in those places corresponding to the unwanted tracks 22. Thus when film 26 is developed, it will produce a photograph of the required tracks only Fig. 5 (not shown). Figs. 6 and 7 (not shown) give practical details of the copying apparatus. The original negative can be chosen from a negative reel (10) winding across from one spool (40) to another (40'). The light-sensitive copy film (26) can also be wound across from one light-tight cassette to another, and clamped against the negative (10) by vacuum means. Vacuum means can also be used to hold the blank sheet against support 20.
