Abstract: An ingot mold for continuous casting of metal strips or thin slabs has a funnel-shaped, charged are which is tapered to the format of the cast strand, and two ingot mold plates which are deformed in relation to each other and which have curved pouch-type broad side wall sections. The curvature of the curved pouch-type broad side wall sections is elliptical in the cross-section thereof.

Abstract: The invention relates to an ingot mould for continuous casting of metal strips or thin slabs, comprising a funnel-shaped, charging area which is tapered to the format of the cast strand, and two ingot mould plates which are deformed in relation to each other and which have curved pouch-type broadside wall sections. According to the invention, the curvature of the curved pouch-type broadside wall sections is elliptical in the cross-section thereof.

Abstract: A method of cutting a body made of a metal or metal alloy which comprises heating the body to or drawing cutting to a temperature at least equal to 200° C. The metal body can be a continuously cast steel slab.

Abstract: An apparatus grinding a steel billet to remove surface cracks. The billet is advanced in the direction of it longitudinal axis while being rotated. The apparatus includes a grinding wheel mounted in a bearing in a movably mounted support member. In order to accurately and simply control the penetration depth of the grinding wheel, a stop member is mounted on the support member. In one embodiment, the stop member is a segment of a circle mounted eccentrically relative to the grinding wheel. In another embodiment, the stop member is a segment of a spiral mounted coaxially with the grinding wheel. The stop member engages the surface of the billet. Two arrangements are described for rotating the billet at an increased speed while grinding the edge regions.

Abstract: A pneumatic hammer-tool designed for driving fastener bolts, in which a piston within a cylinder is charged with compressed air and progressively accelerated in order to drive a fastener bolt, is constructed in such a way that the wall of the cylinder is interrupted by windows on the retracted side of the piston. The axial extension of the windows is less than that of the piston. The cylinder is surrounded by a housing which is connected to a compressed air supply. As the piston is advanced forwardly from its rest position it opens the windows in the cylinder in such a way that compressed air can flow into the cylinder from the surrounding housing and charge and accelerate the piston. In this way much greater kinetic energy is produced. Unintentional actuation of the hammer tool is safely and reliably prevented by a mechanical and a pneumatic safety device.

Abstract: A one-piece open-ended water-cooled continuous casting mold and a method of making it to improve the service life of such mold made up from galvanically precipitated layers of which an inner layer consists of a wear-resistant metal such as nickel and an exterior layer is made particularly from copper. After the mold has been manufactured and while still on the core it may be further improved by application of external pressure.

Abstract: The invention relates to a process for the production of small moulded components by die-casting of metals. In this process, the metal to be melted in a crucible is limited to the charge weight for casting in a single die. Heat is supplied electrically and interrupted during casting. A metal heel is retained in the crucible so that its heat content allows compensation of a large part of the heat loss during said interruption of heat supply.

Abstract: A friction bearing having a plurality of projecting bearing portions for supporting a component intended to move over the bearing wherein each bearing portion has a bearing surface which is variably inclined with respect to the co-acting surface of the component, the degree of such inclination of the bearing surface progressively decreasing from a maximum to a minimum in the direction of movement of the component relative to the bearing.

Abstract: A bending apparatus for bending individual sheet and strip blanks and having a bending punch curved to a radius less than the desired bending radius. Tip-supports are arranged at either side of the punch and are pivotable in the bending plane. Each support has a supporting pad for holding the blank and the pivotal articulations of the supports are arranged beneath the pads and spaced horizontally from the edges of the pads facing the punch.

Abstract: A holding device for a manually portable drilling machine includes a detachable tension element which is attached at two mutually opposite points to a carrier member for the portable drilling machine, the tension element being sufficiently long to encircle at least the horizontal circumference of the object to be drilled at the vertical level of the hole to be drilled. In addition the device includes a resilient bracing means provided between the portable drilling machine and the tension element when the drilling machine is located at a drilling site and the tension element is secured to the carrier so as to be in tension around the object to be drilled.

Abstract: A method of securing a patch of resilient material to a surface, in which method the patch is applied to the surface so as to form a curved clearance between itself and the surface, pressure is applied to press the central region of the patch against the surface, and the edges of the patch are subsequently secured to the surface. Also provided is an apparatus for carrying out the method, which apparatus includes a fluid pressure ram and means for supporting this in relation to the surface to enable the pressure to be applied to the patch. Means are provided for securing the terminal portions of the patch to the surface during application of pressure by the ram.
