Patent DE-3166854-D1 (DE)
Title: Process for producing deuterium enriched water during the production of hydrogen
Inventor: MANDRIN CHARLES DR
IPC: C01B5/00
Filed: 1981-08-28
Granted: 1984-11-29
Abstract: The synthesis gas plant is operated in n successive periods. During the first period, fresh water in excess is supplied to the synthesis gas plant (1) and the waste water from the resulting mixture is separated in a condenser (8) and supplied to a storage container (25). During the next (n-1) operating periods the waste water stored in the container (25) is used as freed water for the synthesis gas plant (1) and the waste water obtained on each occasion is stored in layers, depending on its deuterium concentration, in the container (25). The waste water having the highest deuterium concentration, obtained during the last operating period, is introduced into a second container (24) and supplied therefrom to a heavy-water plant. In order to recover deuterium from the gas mixture leaving the condenser (8) and consisting of hydrogen, steam and residual components, the gas mixture is introduced into an exchange stage (38), in which the gas mixture is brought into isotope exchange in counter-current with additional water, as a result of which the additional water becomes enriched in deuterium and is supplied to the synthesis gas plant.

Pressure between the two shells is equalized through a vent hole (58) formed through the bag. The bag comprises a membrane forming front and rear faces joined along peripheral edges. The disposable bag includes a laminated filter (70) which lies flat between the front and rear faces of the bag when the bag is collapsed. The filter is sealed between the two faces of the bag along one edge thereof and is joined to the rear face of the bag along its opposite edge to define inlet and outlet chambers. Preferably, the shells are of clear plastic molded to conform to the shape of the expanded bag within the chamber.

Title: Matrix control circuit for a memory display
Inventor: LORTEIJE JEAN H J
IPC: H04N3/12
Filed: 1984-01-13
Granted: 1989-01-12
Abstract: The shift registers of the video memory are of bj bits, where j represents a number of between one and m. The input of each of the shift registers is connected to receive information input signals for a respective column. A common signal input line supplies a further shift command signal for shifting all the registers at the end of each video line period. AND gates act with an OR gate to couple the data shifted into output bits of the column shift registers, at the conclusion of the video line period, to the data output terminal of the corresp. column. The video memory is used for storing column brightness data and its information inputs are coupled  with the corresp. outputs of the series-parallel converter which is connected to the digital video input.

Title: Mixture-measuring system for a combustion engine
Inventor: BRAUN GUNTER
IPC: F02D41/04
Filed: 1984-12-22
Granted: 1989-05-03
Abstract: The invention is directed to a mixture metering arrangement for an internal combustion engine with a digital data processor, particularly a microcomputer, the signal processing pattern of which is governed by clock pulses, and with a signal generating means which delivers analog output signals. The signal generating means is responsive to operating parameters of the internal combustion engine and is an exhaust gas sensor responsive to the air ratio Lambda. The exhaust gas sensor is used in a closed-loop control system to influence the air-fuel ratio and changes its output quantity at the air ratio of Lambda=1. In this arrangement, a correcting stage corrects the influence of a delay time (tv) connected with the clocked signal processing on the mixture formation. The delay occurs in the transmission of the change in the output of the sensor. Two methods are indicated for the mode of operation of the correcting stage by means of which a mean value shift of the quantity (FR) influencing the mixture formation is avoided and the concentration of toxic substances in the exhaust gases is minimized. Flowcharts are disclosed to realize the invention by means of a suitably programmed microcomputer.

Title: Process for manufacturing electronic components using soft soldering flux based on carboxylic acids
Inventor: KERNER RUDOLF A
IPC: B23K35/363
Filed: 1984-05-14
Granted: 1989-08-24
Abstract: The present flux is preferably used in electronics and electricity. The flux is characterized particularly in that welding waste are easily removed, without time-limit and without degradation (auto-oxidative) of the flux itself as it would be the case for example during the activation of the flux by aromatic carboxylic acids. The characteristics in relation to corrosion and surface resistance, as those required by testing conditions according to standards DIN 8516 and DIN 8527 applied to a halogen-free flux, according to DIN 8511, type F-SW 32, are guaranteed. The advantages of said flux are obtained by introducing mono-, di- or poly-carboxylic alicyclic acids presenting at least one carbon ring, or derivatives thereof using mono-, di- or poly- or ceto-carboxylic acids. The properties of the flux may be further improved by using in conjunction quaternary ammonium salts. The base composition disclosed hereabove enables to obtain soft soldering flux having various characteristics, thereby providing a flexibility to their use (for example flux applicable to flux welding processes, welding pastes, constituent envelopes of lead wires or lead cores).
