Title: Method and device for producing a steel-sheet trough as a lid shell for a reinforced-concrete manhole cover
Inventor: STEWING ALBERT
IPC: E02D29/14
Filed: 1981-11-12
Abstract: The invention deals with a method of producing a steel-sheet trough as a lid shell for a reinforced-concrete manhole cover, a steel-sheet blank with punched holes for inserting anchor bolts and with or without vent pipes being bent to form the steel-sheet trough of base and encircling collar and being welded in its corner areas. Before the welding of the outer corners formed from the bent-up collar sections, pick-up stiffeners are welded into the inner corners. After the corner welding, the steel-sheet trough is turned and support profiles are welded onto the upturned base underside. The anchor bolts inserted into the punched holes are then welded into the base in diagonally opposite positions in pairs from the outside to the inside or vice versa in an intersecting diagonal welding sequence under shielding gas. Any vent pipes are also welded into their punched holes in a diagonal welding sequence. These welding sequences ensure a flat support form which makes subsequent aligning work unnecessary. <IMAGE>

Patent DE-3151482-A1 (DE)
Inventor: BERZ GERHARD
IPC: B65G57/18
Filed: 1981-12-24
Abstract: Small bundles of elongated profile elements that arrive generally regularly at an intake station wherein the elements are first displaced in a transport direction generally perpendicular to their elongation direction from the intake station to a pickup station. There they are arrested in a pair of groups with the elements closely spaced in their respective groups and the groups widely spaced in the transport direction. The pair of spaced groups is then picked up without substantially changing its spacings and the pair of spaced groups is deposited in a takeoff station while further pairs of spaced groups are formed in the pickup station. These further pairs are then picked up and deposited on top of the respective groups in the takeoff station to form a pair of stacks each constituting a bundle. For nesting the elements it is possible to invert every other pair of spaced groups before depositing same in the takeoff station.
Patent DE-3201763-A1 (DE)
Title: Optical transmission path
Inventor: NEUMANN WALTER ING GRAD
IPC: H04B10/00
Filed: 1982-01-21
Abstract: If the fibre line is destroyed in an optical transmission path, laser light emerging from the fibre ends at the break point may endanger people. The intermediate regenerators of the optical transmission path are fitted with signal detectors and switching means, and the line terminal devices are fitted in addition with logic circuits, time circuits and signal generators. The afore-mentioned units interact in such a way that all optical transmitters which transmit into the defective field are automatically de-activated. Once the transmitters have been de-activated, the optical path remains in a condition which allows the defective field to be located from the line terminal devices. The optical transmission path is returned to service after repair from the line terminal devices.

Title: Device for converting solar energy into heat
Inventor: KIRCHMAYER HERMANN ING GRAD
IPC: F24S90/00
Filed: 1982-04-21
Abstract: The device for converting solar energy into heat comprises a solar collector consisting of a large number of collector elements (1) which can be fixed on a support surface, interconnected and connected to a heat-transfer fluid system. These collector elements in each case have, in addition to a first heat-transfer fluid duct (6) facing the sun, a second duct (7) which is aligned transversely to the first duct (6) and is in contact with the ambient air. The first duct (6) is in normal operating position connected to a first accumulator (36) for higher temperatures and the second duct (7) is connected to a second accumulator (38) for temperatures which are lower in relation to the first accumulator (36). If the temperature of the circulating heat-transfer fluid falls below a predetermined minimum value which is determined by a temperature sensor (42), the first duct (6) can be separated from the first accumulator (36) via a reverse valve (44) and connected to the second accumulator (38). To achieve particularly high capacity with small dimensions, the first duct (6) is, with its upper side situated below a light-permeable cover (8), directly in contact with the ambient air exclusively when the temperature falls below a predetermined value and the second cover-free duct (7) is, both with its upper side and with its lower side, constantly directly in contact with the ambient air. <IMAGE>

Title: Capacitive pressure distribution measuring mat
Inventor: BRUNNER WOLFGANG DIPL ING
IPC: G01L9/12
Filed: 1982-07-23
Abstract: In order to reduce disturbing influences in the case of capacitive pressure distribution measuring mats and in order to achieve an increase in the measuring sensor density which is made possible as a result in each case one network having two diodes and one resistor are fitted on each of the rows of a capacitor matrix on the side of the measuring mat from which the measured voltage is directed away. Furthermore, an impedance converter and a further resistor are fitted on the measuring mat. As a result of the impedance conversion of the measured signal which can be achieved in this way and the control of the rows by low-resistance DC voltage sources, disturbances which are caused by the intrinsic capacitance of the connecting leads are prevented. Rows which are not addressed can be connected to a fixed potential by means of this arrangement which prevents adjacent rows influencing the respective measuring row. Surface voltages on the loaded side of the measuring mat are reduced by the use of conductive silicon-rubber strips. These strips act as capacitor plates which are conductively connected to one another in the form of columns. The measuring mat is screened by a conductive silicon-rubber film.

Inventor: ZECH HANS-JOACHIM DR
IPC: C08G63/54
Filed: 1982-12-28
Abstract: Unsaturated polyesters based on isophthalic acid are used as additive binders in coating agents. With the use of these polyesters, the resultant coatings have an adhesiveness to metallic substrates to be protected which is improved in relation to the comparable state of the art coatings. Furthermore, coatings are obtained by which the conditions for the protection of metals from corrosion (good adhesion of the coatings on metallic, in particular, critical metallic substrates, and good resistance of the coatings to environmental influences, in particular, good resistance to hydrolysis) are improved. Hence, improved protection from corrosion is achieved.
