Patent DE-19612989-A1 (DE)
Inventor: KANT MICHAEL DR
IPC: C07B41/06
Filed: 1996-03-22
Abstract: The invention relates to transition metal catalysts based on inorganic-organic polymers of general formula M(O3ZW)x(O3Z-X-ZO3)y(((O3P-)wY-)n-PR3-n)z, wherein M is a tetravalent metal, Z is a pentavalent atom, the condition x+2y+n.w.z = 2 applies, and W, X, Y and R represent organic groups. An essential part of the invention is the preparation of phosphanes derived with free phosphonic acid groups; this prevents the unwanted quaternisation of the phosphane groups which can occur in known processes for synthesising layer structures of the above formula. The layer structures are suitable as polymeric ligands for transition metals and can thus form complex catalysts. For example, composites of [Rh(CO)2(acac)] and Zr(O3PCH3)x(O3P-(CH2)6-PO3)y(o-O3PCH(OH)-C6H4-P(C6H5)2)z, a condition being that x+2y+z=2, x >/= 0.5, y </= 0.5, are suitable for hydrofomylation processes in the liquid and gas phases.
Patent DE-19613369-A1 (DE)
Inventor: MUNNECKE GUSTAV-ADOLF
IPC: F03G3/00
Filed: 1996-04-03
Abstract: The object of the invention is to use centrifugal force to produce energy in an environment-friendly, economic manner for driving purposes or for decentralised electric current or heat generation. The figure shows the simplest embodiment of the device. It consists of a rotary aggregate with accumulator (1), switchable motor/generator (3), and a rotary frame (5) with weights (10) that can be moved in the radial direction and that are linked by cables (9a, 9b) to a cable drum (9) arranged at the centre of the rotary frame (5). The device works cyclically. At the beginning of a working cycle, the rotary frame (5) is rotated by the motor (3). When the maximum speed of rotation is reached, a stopping device for the weights (10) is triggered, so that they are projected by the centrifugal force to the periphery of the frame, unwinding the cables (9a, 9b) from the drum (9) that is also rotated together with the rotary frame (5). When the weights (10) are released, the motor (3) is switched to a generator mode in order to convert the energy of rotation of the rotary frame (5) into electric energy. When the rotary frame stops, the generator is switched back to a motor mode. The energy generated by projecting the weights may also be supplied to an additional generator.
