Abstract: The invention is directed to an apparatus for thermally cutting rectangular metal slabs along a longitudinal axis of the slab. A metal slab is conveyed along a predetermined path of travel while it is being cut by, for example, an oxygen-flame cutting machine. The means for conveying the metal slab comprises a plurality of rollers transversely disposed relative to the path of travel and the cutting machine is arranged above the conveying means and between two of the rollers. The slag created by the cutting is collected and conveyed by a slag duct disposed below the conveying means. Pursuant to the invention, the slag duct extends from between the two rollers adjacent the cutting machine along an axis transverse to the path of travel. In accordance with another feature of the invention, the side edges of the metal slab are sensed and the cutting machine is transversely aligned relative to the path of travel in accordance with the sensed locations of the side edges.

Abstract: A tilt drive is provided for a metallurgical vessel which is mounted on a large sprocket wheel driven by two or more reduction gears. The reduction gears are joined by a torque equalizing apparatus which transmits torque from the pinion of one gear to the pinion of the other, thus acting as a forced synchronizer. The torque equalizing apparatus is effective in both the dynamic and static operations of the drive.

Abstract: Process for removal of sulfur compounds from gases by passing the gases over an absorption mass which, on an inert support having a specific surface area of more than 10 m.sup.2 per g, contains metal oxides which react with hydrogen sulfide to give metal-sulfur compounds and at least 20% by weight of which metal oxides are present in finely divided form with a particle size of less than 40 nm. The gases are passed at a temperature of 5.degree. to 800.degree. C. over the support loaded with metal oxide, and the resultant support loaded with metal-sulfur compounds is regenerated by passing gases containing oxidizing agents over it.

Abstract: A method for continuous casting of metallic strands which provides a maximum compressive stress to the strand at the precise bending point of the strand guide. In this manner, continuous casting speeds of greater than 0.8 m/min. can be utilized without the otherwise present potential for ruptures and tears. Pairs of supporting rollers are spaced along the strand guide. A bending point is defined as the precise point where the arcuate section of the strand guide becomes the linear section of the strand guide. It is at that bending point that the compressive forces on the cast metallic strand are maximized by the selected driving of the supporting rollers, located downstream of the bending point. The number of supporting rollers located upstream of the bending point is not less than twice the number of supporting rollers located downstream of the bending point.

Abstract: The disclosure relates to a display device and assembly for apertured panel boards, etc., and particularly a multi-part assembly including a unitary, molded plastic multi-purpose base which, alone, constitutes one facet of the invention, and which is cooperatively combined with one or more especially adapted wire-like display elements for the support and/or display of merchandise. The molded plastic base member includes a forwardly opening vertical recess extending from top to bottom and cooperatively related to a straddling pair of crossbar-engaging side members. Alongside the forwardly opening recess are upwardly opening sockets for the reception of vertical support sections of one or more wire-like display elements. The forwardly opening recess and bar engaging recesses cooperate to provide an advantageous support of a wire-like display element of a first type, while the associate vertical socket recesses are arranged to support wire-like elements of a second type.

Abstract: A fluid flow restrictor for use in a high pressure valve or the like which comprises a series of closely interfitting concentric cylinders alternately attached to the valve seat and an axially movable valve plug of the valve. In one advantageous embodiment of the invention, various arrangements of slot openings are formed through the several cylinders. The slot openings may be of any geometric shape, for example, rectangular or trapezoidal, and are of sufficient volume to act as expansion chambers for a compressible fluid. The openings of each cylinder communicate with the openings of an adjacent cylinder by various overlapping relationships between openings or by viscous friction flow paths between the cylinders to form restricting flow paths therebetween. Axial displacement of the valve plug will move the interfitting cylinders with respect to one another to vary the flow path dimensions between the slot openings of the cylinders.

Abstract: Channel construction machinery is provided with a levelling and material lining application attachment to thus provide a continuous mode of channel construction operation in either the longitudinal or transverse direction of operation with respect to the longitudinal axis of the channel. The levelling and/or lining attachment is provided with at least one shaft which is mounted and driven so as to rotate. The length of the shaft is proportioned to the length of the embankment section to be worked on. Located about the circumference of the shaft are blade-like elements, whose surfaces are directed at an angle to the axis of the shaft. The shafts and angularly directed blades are mounted on implement carriers of the channel construction machine in a manner such that they oscillate by being connected to vibration actuators. The implement carriers, however, attached to the frame of the apparatus are isolated from the vibrations of the vibrator by damping elements.

Abstract: The disclosure relates to a resilient friction clip adapted to be received over and to frictionally grip the wire portion of a merchandise display hook, such as used pegboard displays. The clip is formed of resilient material, of extruded, or more preferably molded construction. A center aperture is provided for gripping the wire, and a radial slit extends from the periphery of the clip into the center aperture, enabling the clip to be forcibly applied over the wire. A pair of angularly disposed manipulating tabs are formed integrally on the clip, opposite to and symmetrical with the radial slit. The manipulating tabs may be gripped by the fingers and squeezed together, to open the radial slit and greatly facilitate application of the clip onto the wire. Squeezing of the manipulating tab also tends to release the friction grip of the clip on the wire for easy adjustment of its position.

Located within the elongated sections are compressive spring bundles and a shaft bolt which is secured to supporting surfaces of the elongated sections. In this manner, compressive and tensile forces are cpable of being absorbed by the tension-compression rod.

Abstract: The disclosure related in part to a novel and highly superior high bulk pulp formed of lignin-containing fibers, and to process conditions for manufacture of the pulp. The process involves selection of a lignin-containing fiber source, having a lignin content of at least about 10%, and thermomechanically pulping the fiber source under temperature/pressure conditions of 300.degree. F.-350.degree. F./50 psig-120 psig and a refiner energy utilization of about 8-35 HPT/ADT, using a double disc, counter rotating disc refiner. The thermomechanically produced fibers are characterized by a high degree of stiffness, and an extremely smooth surface, free of fine fibril formation and thus substantially non-self-bonding. The new pulp has a wide variety of specialty uses which are attractive in terms of both economics and technical performance, because of the exceptionally high bulk and other distinctive characteristics of the fiber.

Abstract: The disclosure relates to a novel and highly superior filter media formed of random-laid, lignin-containing fibers, and to a process for manufacture of the filter media. The process involves selection of lignin-containing fiber source, having a lignin content of at least about 10% and thermomechanically pulping the fiber source under temperature/pressure conditions of 300.degree.
