Title: Water tight jointing strip for roof tiles - is formed of flexible synthetic material with circular section to fit range of tile sizes
IPC: E04D13/02
Filed: 1976-05-08
Abstract: The water-tight strip is designed for use on joints between roofing tiles and adjacent surfaces such as window-frames. It is made of a flexible synthetic material and the edge which rests on the tiles is reinforced by a second narrower strip of the same material. This is glued to the underside of the jointing strip. The jointing strip can be easily adapted to fit any type of roof tile and it can be glued or welded onto the adjacent surface. Prior to being positioned, the strip has a circular segment and to fit all normal roof tiles, its internal radius is between 120 and 180 cm. for a width of approx. 10-30 cm.
Patent DE-2735011-B1 (DE)
Title: Phase locked loop input signal monitoring circuit - prevents phase errors caused by phase jumps or frequency shifts using phase detector and filter
Inventor: LUEDER RAINER DR-ING
IPC: H03L7/093
Filed: 1977-08-03
Abstract: A circuit for monitoring phase control circuit input signals is designed to detect phase jumps and frequency shifts in order to prevent them from causing a phase shift between the output signal and the desired input signal phase. A phase detector (PD) determines the phase difference between the input signals and an output signal generated by an oscillator and produces an error signal which is returned to the oscillator by a filter arrangement. A switching stage determines the phase and/or frequency difference between the input and output signals and generates a blocking signal which controls the filter so as to halt the control process whent he phase and/or frequency difference exceeds defined limits.
Patent DE-2826167-B1 (DE)
Inventor: BECKENBACH KARL DIPL-ING
IPC: F27B1/20
Filed: 1978-06-15
Abstract: This invention deals with a method of burning crushed or lump-sized combustible material, such as limestone, dolomite, magnesite or a similar material, in an annular shaft kiln having an annular outer shaft and an inner shaft, where the annular and the inner shafts are alternatively charged with fresh air and combustion gases, or are connected with the exhaust gas system. Furthermore, the invention deals with an annular shaft kiln for carrying out this method, which has a shaft insert that is open at the top, whereby the combustion material is selectively fed into the annular shaft formed around the shaft insert, or into the inner shaft which is formed inside the shaft insert. In a first operating position, the inner shaft adjacent its upper end is connected with the exhaust gas system, and combustion gas and combustion air are fed into the outer annular shaft. In a second operating position, the inner shaft is fed with the combustion air and the combustion gas, while the annular shaft adjacent its upper end, is connected to the exhaust gas system. Thus, in the first operating position, the annular shaft has air passed it and the inner shaft has gas flowing through it in counter flow, the flows being parallel, and in the second operating position the annular shaft has gas passed through it in counter flow and the inner shaft has air passed through it in parallel flow.
Patent DE-2920647-B1 (DE)
Inventor: HOEHNE DIETER
IPC: G03F3/04
Filed: 1979-05-22
Abstract: A multicolor printed product includes a base and a plurality of color component images printed on the base in superimposition upon one another. An additional image including a pearl luster pigment is superimposed upon the color component images, preferably adjacent to the uppermost color component image. The pigment is applied more heavily at those areas of the composite image consisting of the color component images which correspond to lighter areas of the composite image, and such pigment is applied less heavily at areas corresponding to rich color areas of the composite image. The printing plates which are used for the printing of the color component and pearl luster images are manufactured with the aid of films obtained by photographing the original in the component colors or by copying from at least one of the color component films. The manufacture of the pearl luster film involves photographic reversal procedure relative to the color component films.
