Abstract: An electric drive for the vehicle or traveling mechanism of a lifting appliance contains a control which controls the switching on of the mechanical brake and the switching of the motor current off and on again. In this case, there is provision, in the event of a changeover from a high traveling speed to slow maneuvering speed, for the mechanical brake to remain released until the maneuvering speed is approached. During this phase, the vehicle is decelerated solely by the internal friction and the rolling friction on the rail, in order to avoid inducing any or any additional load pendulum oscillation.

The through-heated slabs are then hot roughed, followed by hot finish rolling at an initial temperature of at least 960.degree. C. and a final rolling temperature of 880.degree. C. to 1,000.degree. C., to produce a hot rolled strip having a thickness in the range of 1.5 to 7 mm. During this last step, at least 60% of the total nitrogen content precipitates in the form of coarse AlN particles. Thereafter, the hot rolled strips are annealed at temperature of 880.degree. C. to 1,150.degree. C.

Abstract: A strip is continuously cast between rolls that includes a pair of rolls driven in rotation, two side dams urged against the ends of the rolls, and a jack for pressing the side dams against the rolls. The thrust force on the side dams is measured and the friction force exerted on the side dams by the rolls as a result of the rolls rotating is measured. From these measurements of thrust and friction forces, a coefficient representative of friction conditions between each of the surfaces of contact between the side dams and rolls is deduced and casting parameters are adjusted in response to the contact state between the surfaces.

Abstract: A casting roll for continuous casting of metals. The roll comprising a core (2) and a sleeve (3), coaxially arranged one with respect to the other. The sleeve is axially coupled to the core by a inward projection (33) on the sleeve which abuts a shoulder (24) on the projection. The projection and the shoulder are located in a plane (P) substantially median with respect to the roll. The sleeve is radially centered on the core by flanges (5) and (6) which are elastically coupled together. The flanges and sleeve have relieved surfaces (37) which allow the sleeve to expand axially without bowing. The invention is particularly well suited for continuous casting thin metallic strips, especially steel strips, between two of these casting rolls.

Abstract: A side dam assembly for a continuous casting apparatus for continuously casting thin steel strips between casting rolls. The side dam assembly has a side dam for bearing directly against the rolls of the casting apparatus for preventing leakage of molten metal therebetween. The side dam is attached by a pair of belts to an insulating refractory plate which is carried by a cooled panel. To allow axial motion, one of the belts is not rigidly affixed to either the insulating refractory plate or the side dam. The cooled panel is carried by a thrust plate and is urged toward the rolls by biasing elements which preferably comprise a plurality of pistons urged outwardly from the thrust plate by springs. Preferably, the biasing elements are constructed and arranged so that they are distributed over a zone of shape corresponding to that of the side dam and are capable of exerting on the side dam thrust forces independently of one another.

Abstract: An apparatus for applying decalcomania to a curved surface of a container is provided. The apparatus includes a base, first and second curved rigid support members pivotally connected with respect to each other, a band mounted to the end portion of each support member, a heater assembly supported within the band, and a handle linkage adapted to open and close the support members with respect to each other. Movement of the handle linkage causes one support member to close with respect to the other support member, thereby tightening the band and heater assembly about a container for application of the decalcomania. A turn-buckle type adjustment is provided for adjusting pressure applied by the handle linkage.
