Title: Axial single-face seal for components having circular sealing faces
Inventor: ANDOERFER ROLAND
IPC: F16L47/30
Filed: 1985-05-11
Abstract: The invention relates to an axial single-face seal for components having circular sealing faces of plastic, in particular of PTFE, for transporting super-pure chemicals. The object of the invention is to accomplish long-term sealing with low sealing forces by developing an axial single-face seal. According to the invention, this object is achieved by at least one of the components having a circular sealing face which are to be connected by means of flanges having an annular groove on the outer side of the wall, close to the sealing point. In this annular groove there is arranged a flexible supporting ring, which imposes quasi-elastic characteristics on the outer delimiting wall of the annular groove. The position of the supporting ring in the annular groove is secured by a bevelling of the annular sealing face by about 2 DEG  with respect to the axis of the component. The invention is used in the case of axially sealing plastic pipes and fittings. It was developed in particular for PTFE pipes, prone to cold flow. The results achieved with regard to sealing forces to be expended and to long-term sealing are very positive.

Title: High-pressure discharge lamp for use in motor vehicle headlights
Inventor: GAUGEL MANFRED DIPL ING
IPC: H01J61/30
Filed: 1985-05-31
Abstract: In order to produce an asymmetrical light-density distribution of the discharge arc during operation of a metal-halide high-pressure discharge lamp (1), its electrodes (7, 8) have a different temperature gradient. In consequence, the lamp (1) can be positioned more advantageously within a motor vehicle headlight, in that the hotter part of the discharge arc is arranged at the focal point of the headlight. In comparison with known lamps which are used in motor vehicle headlights, improved values are achieved at the axis intersection of the European measurement screen. The different temperature gradient is achieved by one, or a combination, of the following features: the electrodes (7, 8) have a different mass, especially a different diameter; the electrodes (7, 8) have a different emission capability; the discharge vessel (2) is constructed adjacent to one of the electrodes (7, 8) as a paraboloid (11); the discharge vessel (2) is partially provided with a coating which reflects thermal radiation. <IMAGE>

Title: Fitting trough for the conveying trough of a conveyor, especially a scraper chain conveyor with plane guide
Inventor: BRAUN GERT DIPL ING
IPC: B65G19/28
Filed: 1985-06-26
Abstract: The invention relates to a fitting trough for conveyors, in which trough the guiding segments for a coal plane are divided up into a lateral part and a supporting part. The upper and lower limbs of the E are separated from the side wall of the trough, which is E-shaped in cross-section, and are designed as components of the lateral part. The lateral part and the supporting part can be separated in the region of the chain channels for the plane chain and can be connected to the conveying trough in the region of the base sheet and/or of the middle limb of the E. As a result of this, the fitting trough can be attached or disengaged without difficulty, without separation of the chain strands for the coal plane and the conveyor being necessary in the region of the installation site. The chain strands can now rather be extended or shortened in the accessible drive region in future. <IMAGE>

Title: Earth-bearing system for greening
Inventor: DOSE GEORG
IPC: A01G9/02
Filed: 1985-08-09
Abstract: Purpose: greening of façade surfaces and parapets, as well as insulating façade covering. Solution: vertically arranged holders, which are hooked together to form holder chains (a-d) or are manufactured as such from the outset, bear earth-filled channels made of rigid-elastic material, the rear sides of which overlap and the undersides of which are perforated for ventilation and drainage of the earth filling (e). Watering hoses can be laid into the channels or manufactured integrally. The wall mounting is effected with hooks, eyes or clamps. The varied shape for greening on both sides has a symmetrical channel cross-section. Covering channels can also be shaped in such a manner that they can be suspended on one another (f) without additional holders. Advantages: the system allows accurate cutting to all façade dimensions. It replaces other wall coverings, insulates, is uncomplicated in manufacture and mounting, plants rich in species bring a living change in the appearance, it has a heat-regulating effect, is sound-absorbing, dust-absorbing. Most variations cannot be climbed on. Walls remain dry and can breathe. New biotopes can be created thus even in large towns. Explanation of the references: 1 = channel, 4 = perforation for ventilation and drainage, 6 = holder for channel upper edges, 11 = attachment point for the next holder, 12 = fastening point for wall mounting. <IMAGE>

Patent DE-3613806-A1 (DE)
Title: Ink knife arrangement
Inventor: DELVOS KLAUS
IPC: B41F31/04
Filed: 1986-04-24
Abstract: In an ink knife arrangement for the ductor roller of offset machines, provision is made for the ink knife not to be designed to be continuous but to have adjacently arranged, resilient individual lamellae, whose spacing relative to the ductor roller can be adjusted individually via adjusting screws. The lamellae are substantially covered by a covering which only leaves a spring tongue-like front region of the lamellae free in each case. Provided between the underside of the covering facing the lamellae and said front region is a crevice-like gap which is filled with an elastic seal at least in the front region. Furthermore, the maximum adjustment range of the tongue-like front regions of the lamellae provided for the operating function corresponds at most to the dimension of the thickness of the lamellae at their front ends. A sufficient tightness of the bottom of the ink duct is thus achieved with individual lamellae.

Title: Heat-treatment furnace with local heating chambers
Inventor: NAKANISHI YOICHI
IPC: F27B9/02
Filed: 1986-06-09
Abstract: A heat-treatment furnace has a furnace body with an inlet and an outlet. A support charged with material being treated is transported by a transport arrangement from the inlet to the outlet. Situated above the transport path of the supports is a number of local heating chambers. Situated below the transport path in places relating to the heating chambers are lifting devices. In the course of passage through the furnace, the support reaches the place below the respective local heating chambers and is there lifted by the lifting device concerned. The support thus raised blocks the opening section formed in the underside of the local heating chamber, while the material being treated is situated on the support inside the heating chamber. In this state, the material being treated is heated by a heating device situated in the chamber. After completion of the heat-treatment operation, the support with the material being treated is lowered in order to be transported to the next local heating chamber. There, the support is again raised by the lifting device so that the material being treated is treated in the heating chamber. In this manner, the material being treated is subjected to various heat treatments until the material being treated leaves the furnace on the support.

Title: Identity card with visually visible indication of authenticity and process for production of the same
Inventor: LASS JOSEPH
IPC: B42D25/41
Filed: 1986-10-13
Abstract: Information is introduced into a multilayered identity card by means of a laser beam. The recording of this information takes place by irreversible changing (blackening) of transparent plastic material. In this case, plastic materials which blacken under different values of intensity are used for the individual layers of the card. By controlling the intensity of the laser beam, consequently the recording can take place only in one layer or else simultaneously in more than one layer. With suitable selection of the layer arrangement, of the materials of the layers and of the recording parameters (intensity, type width, etc.), images which change their appearance when viewed from different angles are produced. The different visual effects which can be achieved thereby serve to provide an indication of the authenticity of the identity card.
