Patent DE-3309197-A1 (DE)
Title: Process for eliminating oxygen dissolved in water
Inventor: FUCHS WILFRIED DR
IPC: C02F1/72
Filed: 1983-03-15
Abstract: A corrosion protection process based on hydrazine for boiler feed water and for preservation purposes, which is free from organic activators and ensures a high rate of reaction against dissolved oxygen in a broad pH range at low temperatures without neglecting the efficiency in relation to time. The activators used are cationic and anionic complexes of trivalent cobalt with inorganic ligands or mixtures thereof. Preferred activators are (Co(NH3)5Cl)Cl2 and Na3Co(NO2)6. Hydrazine solutions containing these activators are suitable for eliminating oxygen from gases.

Title: Method of contactless measurement of the rotary speed of an impeller in a fluid counter
Inventor: DITTRICH GERHARD DIPL ING DR R
IPC: G01F1/05
Filed: 1983-03-22
Abstract: In order to be able to measure the rotary speed of an impeller (4) in a fluid counter without contact, an ultrasonic transmitter and receiver (5) are mounted on the outside of the counter housing (1), whose ultrasonic pulses (6) are reflected by a wall (7) of the counter housing (1) opposite the transmitter (5). If one of the vanes of the impeller (4) is located in the ultrasonic ray, the echo signal reflected on the upper side of the vane appears considerably earlier in the receiver (5). The presence or lack of a vane is concluded from the different delay. In order also to be able to reliably rule out interfering echoes due to multiple reflection, an amplitude window is also provided next to the time window. <IMAGE>

Title: Rotary engine
Inventor: MENZENBACH MARTIN ALFRED
IPC: F01C1/46
Filed: 1983-08-16
Abstract: Rotary engine for the direct conversion of heat energy into rotational energy. The subject-matter of the application comprises a cylindrical rotary piston through which, proceeding from the centre point, four mixture passages (2) pass cruciformly, which end on the outer circumference, on which two opposing pockets (5) fed with a combustible mixture are located. The rotary piston is enclosed by a fixed cylindrical housing which has four combustion chambers (3) which are regularly distributed around the inner circumference and are overlapped at the sides, starting from the rotary piston. As it rotates, after each 1/4 rotation two combustion chamber configurations formed by the fixed housing and rotary piston are produced which are charged by four rotating fresh gas flows, which are controlled by a fixed separating ring (6). The two combustion chamber configurations are divided by two respectively opposing flaps (15) controlled by cams (17), which on ignition in the larger parts (A) and on reaching the exhaust orifices (12) move away from the axis of rotation owing to the vacuum, in order thereby to permit the explosion of the gases still contained in the smaller parts (B), and at the same time following a further 1/4 rotation by opening wide the admission of gas to the upper parts (3) of the combustion chamber. The release of gases from these is by way of four air flows parallel to the axis of rotation which flow through precisely defined orifices (4) shortly after ignition. <IMAGE>

Patent DE-3428168-A1 (DE)
Title: All-wing elliptical ring configuration
Inventor: SCHULZ DIETER
IPC: B64C39/06
Filed: 1984-07-31
Abstract: In order to provide a climbing performance flight system which additionally permits good cruise performance, sub-surfaces are connected to form an elliptical-ring all-wing system. The result of this is that:   - the induced drag is considerably reduced by surface-related, continuous pressure-difference reversal of the translation flow and incidence-angle-independent zero distribution of the lift in the region of the maximum span in all flight conditions, - the total drag remains low as a result of the absence of further control/stabilisation surfaces, - as a consequence of the static stability produced by a fully-integrated, vertically staggered leading surface, thermally or dynamically dependent incident-flow changes result in a particularly low-drag parallel shift of the respective trimmed-flight attitude without system movement about the pitch axis and/or stabilisation phugoids, as a result of which all incident-flow changes automatically and optimally lead to an altitude gain, - absolutely non-critical stall behaviour results from the aerodynamically and mass-dynamically balanced lift distribution, - the all-wing design permits maximum mechanical strength with low structural weight, - the all-wing design can be used both in the UL region and in the other flight-system region, - the all-wing design can be combined - cost effectively - with very different fuselages without losing its specific flight performance and flight characteristics. t

Title: Sliding door for shower cubicles
Inventor: OEPPING REINHARD
IPC: A47K3/34
Filed: 1984-10-18
Abstract: A sliding door for a shower cubicle is to be designed in such a way that damping of the closing movement of the sliding door leaf is achieved and a slight open position of the sliding door leaf is prevented. For this purpose, the sliding door for a shower cubicle is fitted with a magnetic device for holding it closed, which device is arranged in the region of the horizontal bars (16 and 18) of the surrounding frame and of the sliding door leaf (14). The permanent magnets (19 and 20) are arranged offset relative to one another in such a way that, in the closed position of the sliding door leaf (14), the permanent magnet (20) arranged in the bar (18) of the sliding door leaf (14) is attracted in the closing direction by the permanent magnet (19) arranged in the bar (16) of the surrounding frame or is repelled and, before reaching the closed position, like poles of the permanent magnets (19 and 20) lie opposite one another. By this arrangement, the sliding door leaf is securely held closed and damping of the closing movement is achieved since, before reaching the closed position, like poles of the permanent magnets lie opposite one another. <IMAGE>
