Patent DE-3236549-A1 (DE)
Title: Resilient support for large-area structures
Inventor: BATTERMANN WALTER
IPC: E04B1/36
Filed: 1982-10-02
Abstract: Resilient supports for water tanks or other large-area structures can, on account of their dimensions, in most cases no longer be produced such that they are joined together as integral mouldings of rubber or rubber-like plastics, but have to be put together in situ from endless profiled strands so as to be ready for installation. The difficulties associated with the secure sealing of the profiled strands wound annularly in a plurality of windings are overcome according to the invention in that the adjacent windings are put together underneath one another positively but so as to be able to move in articulated manner within limits.

Title: Method and device for preventing pumping in turbo compressors
Inventor: IVASCENKO ANATOLIJ SEMENOVIC
IPC: F04D27/02
Filed: 1984-03-23
Abstract: The method consists in that the first nominal amplitude value of the alternating component is changed in dependence on the mean value of the absolute amount of a first signal which is proportional to the gas parameter. Furthermore, the pulses obtained are counted out. In addition, a second signal is generated which returns the compressor into the stable operating state at a number of pulses which corresponds to the number of pulses which determines an operating state close to the unstable operating state of the compressor. The second signal is then stored. When a pulse is missing within the first predetermined time of the lack of the pulse, the pulses counted out and the second pulse are deleted. The device according to the invention for preventing the pumping of turbo compressors contains a device (1) for obtaining the first signal, a first filter (2), a first comparison element (3), a second filter (4), a first converter (5), a second comparison element (6) for obtaining pulses, an adder (7), a counter (8), a decoder (9), a first flip flop (10), a first device (11) for changing the operating characteristic of the compressor, a logical AND gate (12), a second device (13) for changing the loading on the compressor, a first delay element (14) and a first deletion unit (15). <IMAGE>

Title: Method for the longitudinal division of metal strip
Inventor: EBERLEIN GUENTER DR RER NAT
IPC: B23D19/06
Filed: 1984-07-06
Abstract: The invention relates to a method for the burr-free longitudinal division of metal strip which has to satisfy stringent requirements and which is processed and machined, for example, for the profiling and/or longitudinal welding of tubes in encasing systems. Strips of this type, before their further machining, are cut at the edges by circular-knife shears. The formation of thin burrs is often unavoidable, and this in turn leads to welding errors which mean that the finished product will be rejected. The aim of the invention is to produce a strip of high cutting quality which can be processed in a fault-free manner in the subsequent processing stages, such as profiling, but especially tube profiling with a following longitudinal-welding process. Associated with this is the object of cutting strips continuously in the longitudinal direction in a burr-free manner. The object is achieved, according to the invention, in that the strip (4) which is running in and which is to be cut passes in an S-shaped manner through the region of the shears by way of a deflecting roller (6) and the edge strips (3) are removed from the cutting zone (7) in a curved manner via the advanceable circular knife (5) in the opposite direction to the strip running direction of the cut strip (2). <IMAGE>

Title: Process for the production of formic acid
Inventor: ZOELFFEL MICHAEL
IPC: C07C51/44
Filed: 1984-08-01
Abstract: In the production of formic acid by hydrolysis of methyl formate and distillative work-up, the discharge of the hydrolysis reactor is fed to a first distillation column (K1), in which methanol and methyl formate are separated from a formic acid/water bottom. The methyl formate/methanol mixture is separated in a further column (K2). A methyl formate part stream is recycled in liquid or gaseous form into the lower part of the first column (K1). This procedure according to the invention prevents the reesterification of the formic acid and thus increases the yield of formic acid considerably. The separation of the methyl formate/methanol mixture in the column (K2) is preferably carried out at a head pressure of at least 10 bar, particularly preferably of 12 to 20 bar, in particular of 13 to 15 bar. The vapours removed at the top of this column are preferably fed to an evaporator of the column (K1) for heating thereof. <IMAGE>
