Abstract: An industrial truck has a lifting mast (1) with a fixed mast (1a) and at least one movable mast (1b) that can move vertically in relation to the fixed mast. A load lifting device (2) can be moved up and down on the movable mast (1b). Located on the movable mast (1b) and/or on the load lifting device (2) is at least one electrical component which is connected with at least one electrical cable (3). The cable (3) is guided through a cable storage device (4) which is constructed according to the pulley block principle.

Abstract: The invention relates to a method for producing a metal alloy, in which in a vessel at overpressure a certain desired content of an alloying constituent, which is gaseous in its normal state, is fed to said metal alloy. The method is designed such that precise addition by alloying of an alloying constituent which is gaseous per se, to a steel alloy subjected to overpressure in a pressure vessel, is made possible.

Abstract: The present invention provides methods for conferring a neuroprotective effect on a population of cells in a subject following a traumatic injury to the central nervous system. Specifically, the methods of the invention provide for the administration of a progestin or progestin metabolite following a traumatic brain injury. The progestin or progestin metabolite is administered at therapeutically effective concentrations that produce a neuroprotective effect (i.e., a decrease in the loss of neuronal activity) and reduces and/or prevents the various physiological events leading to neurodegeneration, such as, cerebral edema and the immune/inflammatory response.

Abstract: The invention relates to an austenitic steel alloy which is corrosion-resistant, tough, non-magnetic and compatible with the skin. The invention also relates to a process for the production of said steel alloy and to uses thereof. The characterizing feature of the invention is a steel containing up to 0.3% C, 2 to 26% Mn, 11 to 24% Cr, more than 2.5 to 10% Mo, 0 to 8% W, more than 0.55 to 1.2% N, up to max 0.5% Ni and max 2 % Si, balance iron.

Abstract: For the low-loss braking of an electrically driven vehicle with two electric motors connected in parallel and arranged one on each side of the vehicle and which are controlled by a pulse control, it is proposed, for one, to brake the vehicle above a prescribed rpm threshold value by useful-current braking, and below it by means of regenerative braking. Secondly, instead of an rpm threshold value, the battery current can also be used as the criterion for one of the two different braking types. A high heat generation in the motors is avoided and energy is saved by this braking process. An electric switching circuit for the conversion of this process is indicated.

Abstract: A method of manufacturing high strength and hard metallic composite layer materials by connecting several metal layers with one another, includes forming the metal layers as flat products by rolling from a metal with low base strength, alloying and hardening the flat products over their whole cross-section with a metalloid by heat treatment in a metalloid containing gas atmosphere, then connecting the flat products with one another by diffusion welding. As metalloids preferably nitrogen, boron and carbon are used. Diffusion welding is performed by hot isostatic pressure method.

Abstract: A high strength austenitic steel having a yield strength above 600 N/mm.sup.2 at 02% permanent strain, containing about 0.5 to 1.5% by weight of nitrogen, about 6 to 12% by weight cobalt, and less than 5% by weight nickel. The steel is treated at about 1050.degree. C. to 1200.degree. C. and then quenched in water.

Abstract: A process of manufacturing a roll suitable for use in a rolling mill, the roll having a cylindrical barrel middle section and a neck at each end of the barrel, wherein the barrel and necks are of different material compositions, by remelting an electrode having a central region corresponding in mass and composition of materials to that desired for the barrel of the roll, two end regions corresponding in mass and composition of materials to that desired for the necks of the roll and a transition region disposed between the central region and each end region, each transition region including the material of the barrel and at least one further material. An electroslag remelting process is used in a water cooled mold. The mold is composed of at least two parts and defines a cavity approximating the final outlines of the roll. The mold has tapered transition regions between a part of the cavity corresponding to the barrel and the constricted cavity regions corresponding to the necks.
