Title: Electrical energy generation process - uses explosion of inflammable material to drive turbine
Inventor: SCHLICHT GUNTHER GUENTER
IPC: F01K25/02
Filed: 1991-08-15
Abstract: The generator uses two pressure vessels (1,2) connected to a system of pipes. Each has an inlet valve (10,11), an outlet valve (8,9) and an ignition device (12,13). When inflammable material in one pressure vessel is ignited, a fluid or gas is forced out of the vessel and through the pipes to drive a turbine (5). From the turbine (5) it passes to another pressure vessel (2) where it collects, is ignited, passes through the turbine and back to the original vessel (1). The whole process is then repeated. One-way valves (3,4) and control valves (6,7) in the piping direct flow through the turbine (5).

Title: Microfilm recording together with production of control blips - has flash lighting source operated at high frequency to produce variable length markings
Inventor: DIETRICH KARL-HEINZ
IPC: G03B27/465
Filed: 1992-06-17
Abstract: The microfilm recording process involves scanning the original item (1) line (3) as it moves at a controlled rate.

Located along side the line scanner is a mask (4) that is illuminated by a flash light source (5b). The flash frequency is selected such that a series of marks or blips are produced (12) on the film alongside each recorded frame. The control pulses operating the unit are of such a frequency that the marks are produced without gaps. USE/ADVANTAGE - Provides variable length identification markings by each frame.

Title: Assembly for filtering of filter fluids - transports fleece on linked belt through sidewall guides, and has smaller dimensions and lower mfg. costs
Inventor: PILLER THOMAS
IPC: B01D29/09
Filed: 1992-06-22
Abstract: A fluid filter assembly has an endless linked belt moving between two sidewalls as it carries a filter fleece, to form a filtration pan into which the liq. medium is introduced. The novelty is that the inner face of each sidewall (1) has a guide (3) through which passes the filter fleece (4) as it is moved along by the linked belt, and by virtue of which the shape of the filtration pan is determined. The filter fleece enters immediately below the fluid surface, the height of which is controlled by a ball cock valve (5). A belt is positioned underneath the guides (3) which glides along on the underside of the guides (3) when transporting the filter fleece (4) by vitrue of the pressure exerted by the filter fleece (4), at the same speed. A seal between the filter fleece and linked belt (2) prevents leakage around the margins and reduces the incidence of fleece wear. USE/ADVANTAGE - The assembly filters fluids by means of a non-woven fleece fabric. The filter pan sidewalls do not have to be rounded and no drive wheels are required to move the fleece through the pan. This enables smaller designs and lower cost manufacture.
Patent DE-4220409-A1 (DE)
Inventor: MEYER STEPHAN
IPC: G01R31/11
Filed: 1992-06-19
Abstract: The invention relates to a process for detecting abnormalities in a line to be examined, in which a signal reflected in the line is detected when a pulsed signal is fed into the line. In order to be able to implement this process particularly quickly and with high precision, a weighting function with a time variation is formed which is characteristic for the behaviour of a line of the same type as the line (1) to be examined when a pulse is applied to it. A single pulse is applied to the line (1) to be examined and the detected reflected signal is weighed with the weighting factor as part of a convolution operation.

Title: Honeycomb shaped catalytic support - produced by deforming structured sheet at paint, where the sheet rotation direction is changed
Inventor: MAUS WOLFGANG
IPC: B01J35/04
Filed: 1992-07-14
Abstract: Metallic honeycomb body is made of partially standard sheet, which curves in convoluted patterns about rotation points (2a,2b,2c; 7a,7b,7c) formed both towards the inside and outside of the body. At these points, the direction of curvature of the sheets is changed so that the sheet can pass back along itself. At least 3 rotation points, pref. at least 4, are found in the outer part and the same number in the inner part of the structure. The central part (17) of the structure is hollow. 1-10, Pref. 3-5 sheets are used to produce a circular structure with the contact points hard soldered together. The structure is then deformed by pushing in at 4 points (2a,2b,2c,2d) and supporting at 4 points from inside (7a,7b,7c,7d) to create a star formation which is rotated and the solar arms compacted against each other. USE/ADVANTAGE - As catalyst supports in exhaust pipes of vehicles. Only a small number of sheets is required to build the structure in a uniform manner. The structure is suitable to accommodate an electric conductor in at least one of the sheets or one of the sheets can be insulated and act itself as the conductor.
