Patent DE-3234322-A1 (DE)
Title: Filter element
Inventor: PRIEFER NORBERT
IPC: B01D25/38
Filed: 1982-09-16
Abstract: In a filter element, a device for removing a filter cake from a filter body is actuated by a piston-cylinder arrangement. The travel of the piston rod is substantially smaller than the length of the filter body. In order to completely scrape off the filter cake, despite the small travel, the filter body (6) is surrounded by a plurality of scraper rings (18). These are rigidly connected together and disposed at a uniform distance from each other, which is the same or smaller than the travel. The scraper rings are coupled to the piston rod. <IMAGE>
Patent DE-3242489-A1 (DE)
Title: Reversible chemical actinometer
Inventor: GAUGLITZ GUENTER DR
IPC: G01J1/50
Filed: 1982-11-18
Abstract: The invention relates to a novel, simple, reversible, chemical actinometer for absolute measurement of the photon irradiation intensity in the UV region between 270 and 350 nm, which is based on trans/cis photoisomerisation of azobenzene, which is followed spectrometrically. The azobenzene can either be dissolved in methanol and melted in a quartz cell or encapsulated in polymer blocks or films. In either case, the basis of the method and evaluation is that the azobenzene concentration must be sufficiently high that total absorption of the radiation to be measured is ensured during the entire irradiation time. The advantages of this chemical actinometer are its reversibility, its ease of operation, the capability for absolute measurement of photon irradiation intensities, the simple evaluation, even during the measurement, and the potential for the number of measurement points per measurement series to be, within limits, as large as desired (important for monitoring the stability of the lamp and the consistency of the measurement values).

Patent DE-3310226-A1 (DE)
Title: Pipe part or fitting
Inventor: KLEINDIENST BERNHARD
IPC: F16L47/08
Filed: 1983-03-22
Abstract: The invention relates to a pipe part or fitting (1), consisting especially of a thermoplastic, having a collar (3) and having a chamber (13). An annular sealing element is arranged in the chamber (13). In the case of structures which have become known in the past, very considerable insertion forces resulted, to some extent, especially when inserting a pipe having an insertion end which had no chamfer, or only an incompletely designed chamfer. Furthermore, there is a risk of the sealing element becoming damaged or being pressed out of the chamber. In order to avoid these difficulties, it is proposed that the sealing element consist of a cavity sealing ring (5) having an integrally formed bead ring (6), the front free end being rolled inwards over an angle of at least 150 DEG , in the form of a roll (12). The roll (12) engages around the bead ring (6) and firmly brackets the latter reliably, in that even in the case of severe installation conditions, the insertion end can be inserted into the collar (3) without damage or without pressing the sealing ring out. <IMAGE>

Title: Microscope illuminator for exchangeable flash guns and high-intensity lamps with the retention of the standard illuminator present in the microscope
Inventor: BURCIK ERWIN DR
IPC: G02B21/06
Filed: 1983-09-03
Abstract: A rigid, two-armed light guide is used to feed the light of the flash gun or of the high-intensity lamp, via a common light-guide output having a circular cross-section, simultaneously with the radiation of the standard light source (observing and setting light) to the illuminating beam path of the microscope. The correspondingly configured and area-enlarged input of one of the two light-guide arms makes optimum use of the emission of the rod-shaped flash tubes or discharge lamps with elongated arcs. The microscope illuminator can be used on numerous microscope models from various manufacturers, and with a plurality of cameras and flash guns for TTL flash control, which can be removed from the microscope and microscope illuminator with few manipulations for the purpose of other, intermediate photographs. Practical tests using trial models of the microscope illuminator according to the invention yielded a substantial simplification in photomicrography in many fields, as well as substantial savings in procurement and operating costs. The same holds for the use of some high-intensity lamps which, because of excessively long filaments or arcs could not previously be rendered useful for microscopy and photomicrography.

Title: Pile-foundation method for drilling and/or production platforms, as well as an apparatus for carrying out the same
Inventor: ISENBERG WILHELM DIPL ING
IPC: E02B17/00
Filed: 1983-10-20
Abstract: The invention relates to a pile-foundation method for drilling and/or production platforms. For this purpose, the foundation piles 3 of hollow design are inserted already in dock into third guide rings 4c and are floated into position together with the standing legs 1a to 1c and are set down at the location. After the standing legs 1a to 1c are set down on the seabed 2, a pile driver 7, held by a carrying rope 9, is let down by means of a floating crane 8. First and second guide rings 4a and 4b respectively are provided to guide the pile driver 7 along one of the standing legs 1a or 1b, 1c. A transition guide 10 (Fig. 9) designed as a partly closed sheet-metal part serves to transfer the standing leg 1a or 1b, 1c from the perpendicular direction into the inclined direction. So that it can follow the curvature of this transition guide 10, the pile driver 7 is of two-piece construction and is connected by a joint 30 which permits swivelling movements in only one plane (Fig. 8). During the first pile-driving blows, predetermined breaking points are opened at the base and at the head side of the foundation piles 3 so that water and the seabed can penetrate into them in order to now remove the undesirable buoyancy, so that the penetration of the foundation piles is assisted. <IMAGE>
