Title: Static energy reserve for static voltage converters in rail vehicles - has capacitor connected through high resistance to supply wire
Inventor: PRADA CESARE
IPC: H02J9/06
Filed: 1977-07-11
Abstract: The device has an auxiliary capacitor for current supply before the converter input filter. Its capacitance is much greater than the total capacitance of the input filter capacitors. This capacitor is connected through a resistor to the supply wire. The resistor resistance is so high that the capacitor can be continuously supplied with h.v. even in case of a short-circuit in the capacitor. It is, therefore, designed for the line overvoltages. This overvoltage is a fraction of maximum permissible overvoltages. The capacitor is statically connected to the converter only when the current collector is not in contact with the contact wire. Thus the capacitor is slowly charged when the current collector is in a continuous contact with the contact wire, and delivers energy to the converter during brief interuptions of the current supply.

Title: Raney nickel catalytic electrode - is produced by coating support with nickel-aluminium alloy powder, fixing and bonding by electroplating with nickel
Inventor: BENCZUR-UERMOESSY GABOR DR
IPC: B01J25/02
Filed: 1978-05-26
Abstract: Raney Ni electrode for galvanic cell, in which the Raney Ni acts as catalyst during operation, is produced by coating a conductive supporting skeleton with powdered Ni-Al alloy, which can also contain 0-50 wt. % Ni powder and opt. other activators, and bonding the skeleton with the powder, after temporary fixing with a binder, by electroplating with Ni from a weakly acid Ni plating bath. Electrodes of this type are useful for electrochemical reactions of H2, e.g. anodic oxidn. of H2 in H2/O2 fuel cells and cathodic prodn. of H2. The formation of NiAl, which cannot be activated by alkali, is avoided, since no sintering stage is necessary, and there are no size limitations, as in the case of the pressing and sintering process.

Title: Fabric-film bonding - using heated blade to cut stacks for layers to be welded at edges
Inventor: BAERTLE HELMUT
IPC: B29C65/72
Filed: 1978-08-29
Abstract: To bond overlapping fabric or film sections, such as for the mfr. of kites, at least two flat and overlaid fabric sections, or film layers are cut together by a hot blade in a straight line while laid on a supporting surface. This gives two double-layered or multi-layered sections, so that the layers in each stacked section can be welded together. At least one layer is hinged upwards and along the welding line. The process gives a simple method to give a clean join to material sections, so that they are formed into the kite components, without distortion.
