Title: Air filter frame - for rapid assembly of V=shaped filter inserts
Inventor: WEBER WILFRIED
IPC: B60H3/06
Filed: 1990-02-13
Abstract: V-shaped air filters made of fleece are assembled using a multi V-shaped folding frame whose shape is defined by rigid side panels. Filter fleece (1) is located in the flat frame (51) which when folded at the hinge (7) produces a bank of V-shaped air filter surfaces upon which are mounted rigid side-panels (61) which define the overall filter box shape. Pref. a linear gasket seals the join between the filter frame and the sides. The frame and fleece are lightly joined., The frame hinges are formed by weak points. The frame sides provide a flat surface upon which the side panels are mounted. The frame sides produce a defined flat surface when folded. When folded, the  filter frame forms a circular, ring-shaped or rectangular side panel. Frame panels incorporate locating and locking components which join them to neighbouring segments. The filter frame is profiled to grip the fleece and secure it in the folded position. USE/ADVANTAGE - The filters so produced reduce manual assembly time in large scale production of air filters such as are found in the automotive industry.

Title: Coupling two intersecting rods by wire
Inventor: RUNKEL ADOLF
IPC: E04G21/12
Filed: 1990-03-15
Abstract: Two intersecting rods (1,2) are secured together, using a wire (63) guided in tongs (14), whose jaws (23,24), are opened to slide it over the intersection point (3) and then shut. The wire is then fed forward in a passage in the long direction in one jaw (23) and passes into a second passage in the other one (24), in which it is clamped. The first shutting movement is generated by placing a thrust head against the intersection point. The wire is parted off at the first passage after reaching the second one, clamping only taking place shortly before rotation to twist the ends together. The twisting is effected by a grip (81) in bearings in the head, which is covered by the jaws, which are clear of it during this operation.

Patent DE-4012109-A1 (DE)
Inventor: OTT KARL ING GRAD
IPC: G01R31/00
Filed: 1990-04-14
Abstract: Proposed is a device for monitoring the operation of an electric/electronic switch controlled by a control circuit, its in-circuit consumers, its control and its connectors. The device is characterized by the fact that at least one logic circuit (5) is connected in parallel with the output stage (3) so that the input-terminal potential (UE), the output-stage (3) output-terminal potential (UA) and a reference potential (Uref) can be applied to the logic circuit. The circuit can differentiate with certainty between the fault conditions overload/short to plus, drop in load and short to earth, and diagnose correct operation of the output stage. Faults (implausible events) in the output stage, the consumer (R), the control unit or its connectors are stored by means of an encoder (7) in an intermediate store (9) which can be read out on interrogation by the control circuit ( mu C) into a store (11) from where they are passed to an interface (P4) with the control circuit. In this way, faults can be attributed to a particular output stage and easily identified. A cut-out switch protects the output stage from overload. The cut-out switch can also switch out output stages at defined points in time, e.g. during the initialization phase.

Title: Undervoltage protected circuit - comprises non-volatile memory, microprocessor and undervoltage detector, thus enables more rapid return to functionality
Inventor: NETH ALOIS DIPL ING
IPC: G06F1/30
Filed: 1990-05-09
Abstract: The circuit with undervoltage protection contains a non-volatile memory (NS), a microprocessor (uP) and an undervoltage detector (UD). The microprocessor is reset by the detector if a supply voltage below a threshold is detected. An undervoltage signal (US) applied to the memory input via a signal extender (T1) causes write protection.  The undervoltage detector output is also connected to a microprocessor hold input (P1).  It is passed to the reset input (P2) only if it exceeds a defined minimum pulse duration. USE/ADVANTAGE - For multiplexer in data transmission system. Returns to operational state more rapidly after supply voltage returns above undervoltage threshold than with conventional undervoltage protection.

Title: Removal of waste water by suction pipe - which has holes for injection of air to form air bubbles for lifting effect
Inventor: MICHAEL HARALD
IPC: B09B1/00
Filed: 1990-06-23
Abstract: Waste water, such as seepage from a refuse dump, is removed by means of a suction pipe (14).  The open lower end (16) of the pipe (14) is immersed in the waste water whilst the upper end is connected to a vacuum source. Where the degree of vacuum of the vacuum source is insufficient to maintain a column of water of the required height in the pipe (14), air is injected into the pipe (14) through a hole (20).  The air forms bubbles in the water column which reduce the effective density of the water and so enable a higher column of mixed air and water to be maintained by the available degree of suction. USE - Pumping of waste water.

Title: Degassing boiler water to remove carbon di:oxide - by diverting steam rising in degassing vessel by vanes and intensively mixing with water droplets passing downwards over series of trays
Inventor: HALLER HANS-JOACHIM
IPC: C02F1/20
Filed: 1991-03-11
Abstract: Boiler feed water is de-gassed by passing downwards over trays having circular weirs while steam rises through passages arranged on alternate sides of successive trays. The steam rises under constant temp., and pressure conditions, and its flow is deflected by vanes so that its dwell time is increased and it is intensively mixed with the down-coming feed water. USE/ADVANTAGE - Used for removing CO2 and oxygen esp. from boiler feed water, or from steam or hot water. Installation and operational costs are reduced, and the availability of the downstream systems is improved due to the intensity of the contact achieved between the water and the de-gassing steam.
