Inventor: ELLIS EDWARD J
IPC: C08F30/08
Filed: 1986-10-07
Abstract: Improved contact lens compositions are achieved through incorporation of a fluorine containing mono or diester of itaconic acid in siloxane polymeric contact lens compositions. Copolymers include components which modify contact lens mechanical, optical and transport properties as well as surface characteristics to achieve at least some compositions having an oxygen permeability of at least DK35 with a refractive index of from 1.35 to 1.5 and a percent hydration below 2 percent of total weight. Contact lenses made of materials of this invention are highly permeable to oxygen and resistant to the deposition of tear components providing extended wear capability through improved biocompatibility.

Date May 3, 1990.A method and an apparatus for cleaning objects with environmentally harmful solvents, particularly halogenated hydrocarbons, in a system which is substantially closed during the cleaning process provides a solution for simplifying the transporting and particularly the handling of such solvents, wherein the endangerment of persons and environment is simultaneously reduced to the lowest possible degree or completely prevented, and which achieves in particular an optimal utilization and recovery of the solvent. This is achieved in that a portion of this solvent is conveyed into a processing space from a large-volume reservoir tank, in that the objects to be cleaned are subsequently wetted with the solvent located in the processing space and cleaned by means of it, the solvent is guided back out of the processing space into a collecting tank after one or more cleaning processes and/or the gas atmosphere in the processing space is filtered and cleaned prior to the removal of the cleaned objects. Only one drawing is to be disclosed with reference to this.

Abstract: The dynamic pyrotechnical penetrometer determines soil characteristics by using the pressure created by a pyrotechnical gas generator to drive a probe rod (1) into the ground, with continuous detection and measurement of penetration. A standard probe rod mounted on a piston (2) containing a magnet (3) is placed in a solenoid-equipped amagnetic tube. A recoiling mass (4) which balances the amount of rod movement created by the gas from a pyrogenerator (5) contained in said recoiling mass, is then also placed in said tube. A unit for acquiring and processing the movement data of the standard rod calculates the resistance of the ground in response to the insertion of the rod.

Date Jul. 3, 1997The invention relates to a method of generating short, cyclically repeating, unipolar or bipolar pulse currents IG, IE for electroplating, and to a circuit arrangement for electroplating with which pulse currents IG, IE can be generated. Electroplating methods of this type are referred to as pulse-plating methods. According to the invention, the secondary winding 6 of a current transformer 1 is connected in series into the electroplating direct current circuit 5, consisting of a bath direct current source 2 and a bath which is contained in an electroplating cell and which is represented by resistor RB. The primary winding 7 of the transformer has a larger number of turns than the secondary winding. The primary winding is controlled with pulses of high voltage and with relatively low current. The high pulse current on the secondary side temporarily compensates in pulses the electroplating direct current. This compensation can be a multiple of the electroplating current, such that deplating pulses with high amplitude are produced. The capacitor 10 guides the compensating current through charging and discharging. Through the invention, the necessity of using in pulse-plating the known electronic high current switches, which work uneconomically because of the great current conduction losses, is avoided.

Abstract: The invention concerns membrane electrolyzers suitable for processes such as water or hydrogen halides electrolysis, as well as electrochemical generators fed with gases containing hydrogen and oxygen for direct conversion into electric energy. These apparatuses generally consist of a filter-press assembly of conductive bipolar plates (2), electrodes (4), sealing gaskets (5) membranes (6) and internal longitudinal ducts for feeding the reactants and withdrawing the products and residual reactants. The invention is directed to the method for repairing said electrolyzers or generators when an elementary cell is malfunctioning. This method comprises making at least two perforations in the peripheral area of the bipolar plates (2) and/or gaskets (5) of the malfunctioning cell to reach distribution channels (9, 11) which connect the compartments containing the electrodes (4) with said longitudinal ducts. A sealing means (agent) is then injected through the perforations (12) in order to form suitable occlusions (14, 15) in the distributions channels (9, 11) and in the perforations (12) respectively. To facilitate the perforation procedure, the bipolar plate (2) and/or the gaskets (5) may be provided with blind aid-holes in the peripheral area. Upon sealing the distribution channels (9, 11) and the perforations (12), the bipolar plates (2) delimiting the malfunctioning cell are externally short-circuited and the electrolyzer or generator is ready for operation. <IMAGE>
