Title: Dust filter bags with internal support frames - of helical springs fixed to longitudinal bar avoiding permanent creasing
Inventor: MARGRAF ADOLF DIPL ING
IPC: B01D46/06
Filed: 1976-06-05
Abstract: The dust filter for gases comprises a number of parallel filter tubes or bags arranged horizontally, vertically or inclined with the clean gas side below them. The gas flows from the outside to the inside of the filter bags and the bags are internally supported to prevent collapse under the gas flow pressure. The internal support for each bag comprises >=2 cylindrical hollow helical springs fixed to a bar extending parallel to the axis of the tube. Under alternating loading when back-blowing is carried out, the filter bag does not sag in a series of short folds, resulting in creased permanent distortion of the bag shape, but instead can sag between support regions as shown dotted over a relatively large area. Thus permanent deformations of the bag resulting in loss of filtering effectiveness are avoided.

Title: Solar heating of water with standby boiler - which is automatically switched on when solar heat is inadequate
Inventor: FUCHS HARTMUT
IPC: F24D11/00
Filed: 1976-06-10
Abstract: An installation for heating water by means of solar energy carrier comprises a water tank, a solar collector and a further energy source, all connected together by a piping system. The temp. of the flow line from the solar collector to the water-tank and the temp. of the water requiring heating are both measured. If the flow line temp. is equal to or lower than that of the water requiring heating, the circulation from the solar collector to the tank is cut off, and, if further heat demand occurs, the other heat source is switched on by means of a controller. The temp. of the water to be heated is pref. obtd. indirectly by measuring the return line to the collector. The flow line and return line sensors are close to each other and operate the controller to change over a three-port valve which interconnects the flow line from the solar collector, the flow line from the conventional heat source, esp. a boiler, and the tank. The automatic control of the change over from solar heating to conventional heating using fossil fuel or the like results in max. economic use and storage of solar heating, so that the heat supplied from the boiler is kept to a min.

Patent DE-2832363-A1 (DE)
Inventor: KNOTHE ERICH
IPC: G01G21/10
Filed: 1978-07-22
Abstract: In order to guarantee the movability of the weighing system, necessary in precision, fine and analytical balances, whilst at the same time maintaining the necessary lateral rigidity, the spring elements ensuring the parallel guidance of the weighing system are provided with a predetermined bending point (6), in which the material thickness amounts to only a fraction of that of the remaining region of the spring element (5). The predetermined bending point (6) is formed by a thickness-etched trough-shaped material web located in the bending axis (7) of the spring element (5). As a result of the thickness etching, it is possible, on the one hand, to avoid the formation of sharp-edged cross-sectional transitions and, on the other hand, to avoid any variation in uniformity in the predetermined bending point. <IMAGE>
