Title: Reciprocating piston engine shaft drive for current generation - having piston rod on eccentric mainshaft giving extended dead centre dwell, with water injected into compressed air converted to steam
Inventor: RAU RUPERT
IPC: F01B29/12
Filed: 1991-12-17
Abstract: The piston engine used to drive a generator shaft (10) has the piston rod (13) connected to an eccentric (11) mainshaft. The design is such that in the vicinity of top and bottom dead centre, the piston (18) remains in that position for roughly a quarter of a mainshaft revolution. During the compression stroke, fresh air is compressed and thereby heated. During the extended duration of the piston at top dead centre, softened water is injected (19) into the reduced cylinder space (17). The resultant vaporisation gives the power stroke, driving the piston down. At bottom dead centre, scavenging air exhausts the cylinder of steam/air mixture ready for the next compression stroke. USE/ADVANTAGE - For generation of electrical energy, esp. in power station. Inexpensive design and operation with no toxic emissions, yet with reasonable efficiency. Cooling system is unnecessary.

Title: Warning personnel and vehicles in track area of railway lines - protecting against approaching and passing railway vehicles, also departing vehicles, using source producing continuous body sound signals in track rails.
Inventor: WETZLER GERD R DIPL ING
IPC: B61L23/06
Filed: 1992-06-11
Abstract: The method involves feeding signals to points (11,12) of a railway track. The solid-borne sound pulses (2a-2d) together with the solid-borne sound signals (6) from the approaching train (7) are disengaged. All solid-borne signals are evaluated in an electronic unit (8). Alarm signals can be generated by this unit and control the alarm units (9) transmitting acoustic and optic signals. A unit (15) is provided for signal regeneration and/or bridging of engineering track facilities e.g. rail insulation, rail isolators and points etc.. Both signals or pulses produced by them, are evaluated to determine whether they are normal, and are picked up in the correct time correlation, thus phase, frequency and amplitude. If this is the case a signal is prepd. for section "clear". Should the pulse not be picked up in an orderly manner, this is an indication of a rail break or similar. A signal is activated for blocking the section, from these pulses. A superimposition of the fed-in signal by foreign signals can be interpreted as a train noise or as manipulation at the travel rail, and necessary measures can be taken. ADVANTAGE - Reliable automatic and continuous monitoring of rails regarding vehicle noise. Satisfies safety standards. Necessary units can be prepd. in short time, assembled and dismantled, monitored and operable.

Title: Treatment of aq. liq. resulting from metal surface treatment - by passage through the electrode spaces of an electrodialysis unit
Inventor: BRANDT BIRGIT DIPL CHEM DR
IPC: C02F1/469
Filed: 1992-09-17
Abstract: The method concerns treatment of liquids, esp. rinsing waters, resulting from chemical and/or electrolytic surface treatment of metals. The liquid is introduced into an electrodialysis unit (3), which comprises concentrate and diluate chambers, as well as electrode spaces, and is separated into a concentrate and a diluate. The method is characterised by the fact that the liquid also passes through the electrode spaces, with breakdown of organic matter and reduction or oxidation of polyvalent ions. The liquid with foreign matter first passes through the electrode spaces (6, 7) and then through the diluate chambers (10). Alternatively, the order of passage of the liquid is reversed. As a further alternative, the liquid first passes through the concentrate and diluate chambers (9, 10) and then the concentrate passes through the electrode spaces. The liquid from the dilute chambers passes through an ion exchanger (13). Alternatively, the liquid from the electrode spaces passes through the ion exchanger before its entry into the diluate chambers. USE/ADVANTAGE - In metal surface treatment plants. Cost-effectiveness is improved by reduction of process steps (with resultant savings in space, chemicals and energy) and by recovery of valuable substances.

Patent DE-4244835-A1 (DE)
Title: Telefax or colour television image coding system
Inventor: DIRR JOSEF
IPC: H04N7/24
Filed: 1992-12-23
Abstract: The coding system shortens the transmission time for black and white digital or numeric longitudinal coding, by using the same codewords for both black and white and for different numbers or characters, with the input sequence of black and white used as the discrimination criteria. When several successive white lines are coded, the transmission time is reduced further by providing the coded number of white lines before or after the white line codeword. During gray coding the gray stages or binary codewords are sub-divided, with deliberate redundancy where characters occur successively, with subsequent transmission in the same manner as the white lines. The transmission time is reduced for colour image transmission by code multiplexing, with the PAM coded information DC biased. The sum alternating current thus varies in phase by up to 90 degrees.
