Title: Fish farming plant water aeration equipment - uses water turbine pump driven by fresh water feed
Inventor: SCHRAGE FRIEDRICH
IPC: A01K61/00
Filed: 1979-05-19
Abstract: The device is for operating fish breeding and farming plants. It is used esp. in a controlled environment using tanks to which fresh water is continuously fed and used water is drained off. A water turbine pump driven by the fed fresh water takes in oxygen from the oxygen supply and feeds it into a tank from which the oxygenated water flows continuously to the individual fish breeding tanks. The tank accepting the oxygenated water is connected with the suction side of the water pump via a pipe line.
Patent DE-2922778-A1 (DE)
Inventor: DISSELBECK DIETER DIPL ING
IPC: B01D37/02
Filed: 1979-06-05
Abstract: The invention relates to a process for separating solids from liquid matter by means of gravity, using a three-dimensional filter element and an alluvial filter layer wherein a gas is fed into the medium to be treated prior to its introduction into the filter element in the form of fine or finest bubbles which accumulate on the solid particles. The particles loaded with air floated up rapidly to the upper level of the column of liquid in the filter element, forming a layer of sludge. Said layer built up continuously an alluvial filter layer at the internal surface of the water-permeable supporting filter element from the bottom upwards along the wall relative to the rising level of the liquid in the filter element. The process, realized in the presence or absence of flocculating agents, results in a higher separation degree with regard to the solids content as well as an increased elimination of the biological oxygen demand.

Title: Air cored inductance for HV circuits - has two windings with secondary switched to reduce short circuit current flow
Inventor: MEINTRUP WALTER DIPL ING
IPC: H02H9/02
Filed: 1979-06-12
Abstract: The free air inductance for limiting short circuit current flows in each phase of high voltage circuits, uses two separate windings for each phase galvanically separated from each other. The supply current passes through the primary winding, and the secondary winding is short circuited by a switching device corresponding to its nominal flow. This switching device can be an electronic device, operated by a given current, or a device which melts when a given current passes through. When the current rises, the current through the secondary winding is cut off, and the inductive resistance through the primary increases to limit the short circuit flow.

Title: Two-for-one spindle assembly - having rapid release sleeve fixing by means of tongued bush
Inventor: KOPISCHKE ROLF
IPC: D01H7/86
Filed: 1979-06-28
Abstract: In a two-for-one spindle assembly, the sleeve on which the supply package is mounted is secured on the spindle shaft by means of a tension bush having a downward-pointing tongue which engages an aperture in the sleeve. The bush is mounted on the spindle between the ball-bearings on which the sleeve rotates, and has a superposed spring which presses the upper bearing against the positioning lip of the sleeve to inhibit vibration. The bush contains longitudinal channels through which lubricant can be fed to the bearings via an additional aperture in the sleeve which gives access to the lubricating nipples. The tongue provides a simple and secure fixing for the sleeve which is rapidly releasable without tools. The single component also provides the means of tensioning and lubricating the sleeve bearings.

Title: Continuity tester input protection circuit - has blocking and limiting diodes in series with limiting resistor
Inventor: LAASS HEINZ
IPC: G01R31/02
Filed: 1979-07-11
Abstract: The input protection circuit for electrical continuity testers with internal current supplies and indicators for testing unpowered circuits gives protection against stray voltages which might endanger the current indicator. This is achieved by using semiconductor rectifier diode switches to limit the voltage drop in one direction and block current in the other. The rectifier diodes (9,10) are connected in series with a resistor (3) with a positive temp. coefficient between the test circuit inputs (1,2). The current source (8) and indicator (7) are connected in series between the junction of the diodes and the junction of one diode (9) and the resistor (3). Zener diodes may be used as an alternative to rectifying diodes. The resistance of the series resistor (3) increases from a low value at the operating temp. to a high value when heated by a current arising from a stray voltage. An alternative diode arrangement may be used.
Patent DE-2945951-A1 (DE)
Title: Centrifugal solid particle separation - involves dust chamber with cleaned medium-carrying dip pipes and additional medium exhaust
Inventor: BIELEFELDT ERNST AUGUST DIPL I
IPC: B04C5/04
Filed: 1979-11-14
Abstract: The solid particle separating device has two particles collecting chambers (20) connecting tangentially to exhaust pipes (21). The exhaust pipes are connected to an exhaust assembly which removes part of the medium (24) through the discharge openings (5). The volume flow (23) leaving the device through dip pipes (8) is reduced. This causes a reduction of the axial velocity of the flow along the external surface of the dip pipes (8) resulting in a reduced distance between the flow line windings. This means that the fine particles carried by the flow lines (22) have a longer period of dwell within the region of the fine separation zone, so that the centrifugal force acts on the particles for a longer period.

IPC: B60H1/03
Filed: 1980-04-02
Abstract: The fast response heater for a vehicle has a turbine driven by the exhaust gas stream and driving a simple air compressor. This supplies air to a flow restriction so that the work performed on the air through the restriction heats the air directly. The heated air is then passed to the normal heater. The heater has few components and is driven off the exhaust as soon as the engine operates. No complex fuel fired heater is required. The exhaust stream is diverted to the turbine (5) by a flow control valve (15) in the exhaust line. The valve operates in conjunction with thermostats to ensure a controlled heating effect. The fast response heater is wound down as the conventional heater takes effect.
