Abstract: Wheel-mounted brake disks which are arranged on both sides of a wheel base of a railway wheel and are fastened by through bolts, the bolt head of every through bolt lying in a countersink of one wheel-mounted brake disk and a nut screwed onto the through bolt lying in a countersink of the other wheel-mounted brake disk, each resting either directly or indirectly on the bottom of the countersink. The wheel-mounted brake disks are designed so that every countersink has an undercut portion that extends down to the bottom.

Abstract: A shaft brake disc, in particular for a rail vehicle, including a friction ring fastened to a hub by way of screws that are passed through a clamp ring at the inner periphery of the friction ring that sits against support flanges, the clamp ring forming a backing support for the screws, is adapted so that the clamp ring and the hub engage one another in a form-fitted manner.

Abstract: The invention relates to a gasification reactor (1) and associated method for the entrained-flow gasification of solid fuels under pressure. The reactor essentially consists of a pressure vessel (4) that can be cooled and an inner jacket (7) that is equipped with a heat shield. At least one crude gas outflow (8) is located at the upper end of the cylindrical pressure vessel and at least one bottoms withdrawal outlet (30) is located at the lower end, the pressure vessel having at least enough space for a moving bed (13), an entrained flow (11) that circulates internally above the surface of the moving bed and a buffer zone (3) situated above said entrained bed.

Abstract: Compositions which, as well as water, contain certain sulfonate salts or polyhydric alcohols together with ethoxylated/propoxylated alcohols and ethoxylated alcohols and also poly(meth)acrylic acid, polymaleic acid or partially hydrolyzed polymaleic anhydride are useful for pretreating textile sheet materials. Further ingredients also render them useful for hydrogen peroxide bleaching. The compositions, which provide the textiles with good primary wettability and good rewettability, are low-foaming. Batchwise pretreatment processes, for example in jet machines, therefore represent no problem.

Abstract: Compositions that include a mixture of three different ethoxylated alcohols with or without further products are useful for pretreating textile materials, especially cotton fabrics. The compositions have acceptable viscosities and are preferably used in the form of aqueous solutions or dispersions. These have little if any tendency to form foam, are highly compatible with enzymes and impart very good rewettability to textiles treated therewith.

Abstract: A process for preparing oil and petroleum-resistant cellular to solid (polyurea)polyurethanes (PURS) with improved physical properties in which a polyether polyol component having a number average molecular weight of from 1000 to 8000 and a polyester polyol component having a number average molecular weight of from 1000 to 6000 are reacted with a polyisocyanate and the (polyurea) polyurethanes produced by that process. The (polyurea)polyurethanes are particularly useful for personal safety equipment and in the construction of automobiles.

Abstract: A wedge wire for use in a wire type screen for screening papermaker's stock is formed with an elongated body (12) having an enlarged head (20) at the inlet surface of the screen. The head (20) is formed with tapered walls (30, 33) that cooperate to define grooves (28) at the inlet surface between adjacent elements including an upstream wall (30) and a downstream wall (33). A radiused protuberance or projection (37) defines one wall of a screening slot (15), with a wall surface (22) of an adjacent wedge wire element. The slot wall formed by the projection (37) is free of sharp edges and is limited in length, in the direction of flow through the slot (15), not substantially exceeding the gap width of the slot. The upstream wall (30) defining the groove (28) provides protection for the slot (15) against impact and damage by contaminants that may be contained in the papermaker's stock. The slot (15) is free of sharp corners so as not to impede flow through the slot.

Abstract: Pressure screening apparatus for screening a suspension of paper fiber stock employs a rotor in which a single impulse or foil member is carried or positioned to move along a discrete portion of the screen surface. This arrangement improves efficiency of operation of the pressure screen by reducing the rotational effect of the rotor on the stock suspension being screened and by providing a less disturbed screening region through which the single foil operates. Embodiments are shown in which multiple single impulse elements sweep over discrete portions of a screen and in which a single foil is combined, in screening apparatus, with multiple foils in accordance with the increase in consistency of the stock as it passes through the screen.
