Patent DE-2843047-A1 (DE)
Title: Bridge circuit for measurement of heat flow - has two thermistors each with amplifier with feedback chosen according to temperature range
Inventor: SCHAEFER OSWALD ING GRAD
IPC: G01K17/16
Filed: 1978-10-03
Abstract: The bridge circuit is to eliminate the non-linearities which are characteristic of thermistors, and it is supplied with a voltage or current proportional to the medium flow. Resistance thermometers in one half of the bridge measure the inlet and outlet temperatures of the medium. A non-inverting amplifier (V1, V2) with feed-back is connected to each resistance thermometer (rV, rR). A positive feed-back resistor (R3, R4) is between each amplifier output and one of the bridge diagonals. Its resistance is a multiple of that of a resistance thermometer (rV, rR), and is specifically chosen so that the enthalpy of the flow is measured with good linearity in the temperature band of interest.
Patent DE-2846100-A1 (DE)
Inventor: HEINEMANN THOMAS
IPC: H01B17/16
Filed: 1978-10-23
Abstract: In order for an electric high-voltage device (1) which is aseismic when floor-mounted to be rendered aseismic when column-mounted, as well, an at least partially hollow column (2) is at least partially filled with granular material, e.g. gravel (4). As a result, the natural frequency of the column (2) is increased far beyond the earthquake frequency. Moreover, in the event of a 'quake energy is "destroyed" by the friction of the grains, by possible comminution of the grains and/or by their plastic deformation. The filling also has a "damping" effect due to inertia. <IMAGE>

Title: Treatment of effluent water streams - using settling tank followed by activated sludge treatment in tray tower with air lift pump to provide recirculation
Inventor: SHIBAYAMA DAIGORO
IPC: C02F3/10
Filed: 1980-02-21
Abstract: Waste water is treated by passing through a settling tank and then an aerated sludge process. The settling tank has a set of baffles to encourage settlement and anaerobic fermentation occurs with breakdown of solids (e.g. paper) into a sludge. The liquor from this settle flows over into a contacter where it flows down over a set of plates to create a zig-zag path. At the side of these is an air lift pump which serves to create a circulatory flow around the tank. This acts as an activated sludge treatment vessel since bacterial growth occurs on the surface of the plates in the presence of the air. Used esp. for treatment of waste water containing human sewage. Allows waste waters from factories, dwelling areas, houses assembly halls etc. to be safely discharged to rivers, moors and seas without a pollution problem.

Title: Soluble dirty laundry PVA bag esp. for hospitals - has inner layer soluble in cold water outer layer in hot water
Inventor: MELCHIOR PETER DR
IPC: B65D65/46
Filed: 1980-05-06
Abstract: A laundry bag, esp., for hospital use to prevent infection of persons handling the bag, is of polyvinyl alcohol foil in two different layers ; the inner layer is soluble in cold water and the outer is soluble in warm water and the bag is closed and sealed by seal welds along the inner layer. Pref. the two wall layers are produced simultaneously by extrusion in the form of co-extrusion. The seam immediately dissolves in the initial cold water wash and therefore opens the bag; after this the remainder of the bag becomes dissolved in the hot water and is flushed away with it. The simplicity of prodn. results in a reduced number of rejected bags.

Title: Coil mfr. for cast insulation - with flexible insulation strip for support of winding terminals
Inventor: KOLLER FRANZ
IPC: H01F5/02
Filed: 1980-07-23
Abstract: The coil is wound on a former or mould (2,3) and subsequently consolidated and insulated by resin casting. To provide a safe support for the winding wire terminals and assist with easier making off of the wire ends a strip of flexible insulation (1) is employed. At least one end of the strip has terminals (6) fitted to it. In the mould the ends of the strip are folded over at 90 degs.
