Abstract: It is proposed that the utilization period of the awning be increased in connection with automatic or manual manual control means in that the awning is preferably incrementally retracted as a function of the magnitude of the wind velocity, as determined through measurement, with the wind velocity being determined in corresponding graduations, and, as a function thereof, in that the control unit for the awning drive motor moves the awning to intermediate awning positions which have priority over all other control influences. In addition to the limit switches, which are present anyway and which indicate the "fully retracted" or "fully extended" positions, a plurality of intermediate sensors, corresponding to the number of desired increments, are disposed to determine the intermediate positions, with the signals output by the intermediate sensors, which indicate the actual position of the awning being compared with wind-velocity-determined awning setpoint position signals.

Title: Belt end bonding - removes part of the covering material round the insert without changing outer belt surface
IPC: B29C65/00
Filed: 1990-06-07
Abstract: To join two belt ends together, of one or more belts with at least one fitted with an insert covered by the belt material, the insert (10) at least at one belt end (12, 13) is partially exposed by removing a cross section of the covering material (11). Pref. the cross section of the covering material is removed only where it passes round the insert so that the insert is exposed while the outer dimensions of the covering are unaffected, to give a smooth outer surface at the ends of the belt. Before the insert is exposed by partial removal of the covering material, the ends are cut across their longitudinal axis to give butts for bonding where the end of the ensert and the covering material are on the same vertical plane. Alternatively, the insert material at one or both of the belt ends projects slightly beyond the vertically cut end face of each belt end. End of the insert is exposed by a ring groove formed round it within the covering material in one or both belt ends directly at the insert material, developed by machining particularly by turning, stamping or melting. Single-strand insert material is opened out in the ring groove area, pref. by untwisting at its end or the ends of strands or woven materials which have been braided together. When the belt ends are brought together, they are heated sufficiently for the covering material to melt and pref. fill the ring groove zone. ADVANTAGE - Method gives a strong bond at the joint between the ends of the belt, without build-up of welding or other bonding material.

Patent DE-4139242-A1 (DE)
Inventor: PLESCHIUTSCHNIGG FRITZ-PETER D
IPC: B22D11/12
Filed: 1991-11-26
Abstract: The invention relates to a process for the production of feedstock for rolling with initial dimensions for a longitudinal rolling mill. In order to influence the solidification of the strand during the continuous casting of steel in such a way that centre-line segregation is eliminated or virtually avoided, it is proposed that molten steel be poured into a water-cooled continuous casting mould in which the steel partially solidifies with the formation of an annular strand shell with a round or oval shape in cross-section or a polygonal shape with more than four angles and has a minimum circumference of 200 mm, the strand thus produced in the mould is reduced in cross-sectional area underneath the mould up to the point when complete solidification has occurred by supporting means which act on the strand in a manner which deforms it, such that, while essentially retaining its peripheral length, the strand is deformed into a polygonal cross-sectional shape with at least four angles or an oval or round cross-sectional shape. <IMAGE>
