Patent DE-4224690-A1 (DE)
Title: Membrane sepn. process for solns. with temp. and/or pressure controlled recovery of solute - by cooling retentate stream to supersaturation or reduced pressure flashing
Inventor: HEINE WILHELM
IPC: C02F1/44
Filed: 1992-07-25
Abstract: Process for separation of liquid mixtures (solutions) of various materials, into their components by use of a membrane process, with production via a membrane separator step of a component material depleted solution (Permeate) and a component material enriched solution (Retentate). Novelty is that for separation of the component material enriched solution (retentate) into a solid residue (solute) and a solvent residue, the component enriched solution into the membrane stage is concentrated up, and that in a subsequent process step, the component material residue is precipitable from the solution (retentate). Membrane separation process with reduced energy consumption. USE/ADVANTAGE - For recovery of both solvent and solute from waste solutions, e.g. recycling of effluent water. Concentration and feed temperature of solution are controlled, as are membrane operating conditions (viz. pressure), so that the retentate solution after emerging from the membrane stage is supersaturated and precipitates solute, e.g. on cooling or flashing.

Title: Optical signal transmission procedure - reducing output power of optical amplifier when line breaks and returning to normal after short time after line is restored
Inventor: AFSAR ERDAL DIPL ING
IPC: H04B10/00
Filed: 1992-11-28
Abstract: Optical signals are transmitted over a transmission line (U) from a transmitter (S) to a receiver (E) via an optical amplifier (V). The optical receiver (E) provides a switch-on signal (UE) to the amplifier (V) which is then regulated to its normal output power (NAN). If the transmission line (U) is broken or interrupted, the signal (UE) is not provided from the receiver (E) to the amplifier (V) and the amplifier (V) is thus regulated, by the controller (18), to give a reduced output power (NAV). After the interruption has been removed, the output power (NAV) of the optical amplifier (V) undergoes a low frequency modulation for a short time (tm). After this time, the output power is reverted to its normal level (NAN). ADVANTAGE - Ensures safe and reliable operation and data transmission.

Patent DE-4303317-A1 (DE)
Inventor: GAUPP OSVIN
IPC: H02G5/00
Filed: 1993-02-05
Abstract: A converter bridge (7) consists of at least two half bridges (2.1, 2.2) which are connected to each other via busbars (3.1, 3.2). The busbars (3.1, 3.2) consist of at least two busbar parts (8.1, 8.2) and are arranged with mirror symmetry in the converter bridge with respect to a mid-plane (7). The directly opposite busbar parts (8.2) have a relatively small conduction cross-section. Because of the mirror-symmetry arrangement, a high-frequency, backward-flowing auxiliary component of the current flowing through the busbars is concentrated in the directly opposite parts (8.2) of the busbar and is efficiently damped by the relatively small conduction cross-section. A low-frequency main current component contrastingly flows substantially uniformly distributed over the profile of the busbar. <IMAGE>

Title: Semiconductor device for allowing a simple external determination of the use of a redundant circuit and semiconductor memory device for this
Inventor: KOMATSU TAKAHIRO
IPC: G11C11/401
Filed: 1993-12-23
Abstract: A dynamic random-access memory (DRAM) comprises an improved circuit for determining redundant use (15), a redundant fusing circuit (11) for programming a defective line and also a redundant enabling circuit (10) for enabling the redundant fusing circuit. The circuit for determining the redundant use (15) comprises a switching element, which responds to a signal for redundant use ( PHI RR) from the redundant enabling circuit for conducting. In an operating mode for determining redundant use, high voltage is applied through an external connection (38) and the use of a redundant circuit is determined by the presence of current flowing into the circuit for determining redundant use. Since a fusible element is not required in the circuit for determining redundant use, the integration density is further improved, thereby allowing at the same time a simple determination of the use of a redundant circuit. <IMAGE>
