Title: Protection for pipes, piping systems and pipelines against the effects of frost
Inventor: GROZA IGOR
IPC: B65D81/18
Filed: 1987-05-15
Abstract: The invention serves to protect containers and pipes filled with liquid from damage due to frost or freezing. In this case, a plastic element which, depending on requirements, is solid or filled with gas is introduced into the container or pipe, which element absorbs the majority of the pressure, occurring when the liquid freezes, due to compression and thus relieves the pressure on the walls of the container or pipe in such a way that bursting or leakages are ruled out.

Title: Method for the hot rolling of bar stock
Inventor: SCHULZE BERND DR ING
IPC: B21B15/00
Filed: 1987-08-05
Abstract: Method for the hot rolling of bar stock which can be employed with the use of a longitudinal tension with a forming effect in rolling installations with an HV layout. The aim of the invention is to increase the effectiveness of forming and to attain a flexible mode of operation in the continuous hot forming of bar stock on separate roll lines of modular design. The object is, with a maximum reduction in height, to use the longitudinal pulling actions with a forming effect to intensify the forming process. According to the invention, the object is achieved by the fact that, in single-strand operation, with two roll stands forming a compact double roll-stand unit, free entry into the first stand takes place, the emerging cross-section having, upon entry to the second stand, a bo/ho ratio = 0.5, the longitudinal compressive forces from the first stand contributing to this, guaranteeing a relative reduction in height of at least  epsilon  = 60%, and, as the thickened bar ends which occur pass through, the matching of rotational speed in the double rolling-stand units is performed in conjunction with the variation of the reduction in height in the first stand.

Title: Fire-assistant hall structure by a composite steel construction method
Inventor: ANDRAE WOLFHART DR
IPC: E04B1/94
Filed: 1988-06-07
Abstract: Difficulties in the production of conventional fire-assistant composite steel/concrete halls, result, on the one hand, in that steel beams with concrete-filled chambers entail high outlay to produce and, owing to the high weight thereof, can be transported and laid only with difficulty and, on the other hand, in that steel-construction accuracy is necessary for the junction points, said junction points usually having to be protected subsequently by filling them with concrete. In the case of the hall according to the invention, the supports comprise steel hollow profiles and the beams comprise steel trough profiles, which are fitted together in the manner of modular construction. The connections between support and beam comprise perforated metal sheets which engage, through slots in the support casing, into the support interior, on the one hand, and into the interior of the trough, on the other hand. By virtue of filling supports and beams with concrete on the building site, a load-bearing skeleton is obtained. The composite reinforced-concrete floors comprise prefabricated reinforced-concrete slabs which have a saddle-like cross-section and are provided along their borders, on the upper side, with a cutout with projecting reinforcement, with the result that, in order to produce a monolithic frictionally locking floor slab, it is likewise necessary only to fill said cutout with in-situ concrete. <IMAGE>

Title: Pneumatic hoist with precise load positioning - has linear motion transferred to shaft with fail=safe brake and pneumatic sensing valves
Inventor: RISCHE GERD DIPL ING
IPC: B23Q5/58
Filed: 1989-10-10
Abstract: The purpose of the invention is to control a pneumatic cylinder type hoist such that widely varying loads can be lifted and precisely positioned, and the load can be sustained in the event of power failure. The cylinder (1) hangs from a shafer (2) which is mounted on a tranversing carriage (d). At the gripper end of the piston rod (3) is fastened an outer cylinder (8) which moves with the piston rod and has a peg (10) linked to an endless chain (11) running on two sprockets (12, 13). Movement of the hoist therefore causes shaft (2) and a braking disk (17) to rotate. A brake reaction disk (18) is spring loaded against the braking disk (17) but is released by actuation of a pneumatic cylinder (20). A radial arm on the brake reaction disk permits limited movement between two stops and also switches two sensing valves forming part of the control circuit. The circuit design causes the air pressure to be balanced against the load before the brake is released, thus enabling varying loads to be lifted at the same speed. USE/ADVANTAGE - Pallet loading systems; load manipulation in foundries refuse sorting systems. Low cost design with fail safe features.
