Title: Device for fitting a profiled rail to an apparatus housing
Inventor: BOHRMAN ROLAND
IPC: H02B1/48
Filed: 1987-12-03
Abstract: The profiled rail (12) is fitted in a latching manner by means of a profiled spring (10) to a comb-like rib (14) which is a fixed component of an apparatus housing. The profiled spring (10) has a mounting section (28) which has a U-profiled shape and is plugged in a clamping manner onto the rib (14), flaps (60) which are bent into the U-opening engaging in blind mounting openings (48) in the rib (14).

Title: Method and plant for spent oil reprocessing
Inventor: DRESPA GERD
IPC: B01D53/72
Filed: 1988-04-27
Abstract: For reprocessing spent oil, and especially for reprocessing without pollution of the environment, a method and a plant are used wherein the spent oil is preheated via distillation gases and then distilled by combustion of the distilled spent oil itself. The liquid and solid residues are exposed to the flame produced during the combustion of the distilled spent oil, while the gaseous residues are heated to a temperature above 1200@C in a long-period residence chamber designed as a flue gas furnace. For igniting the solid residues and/or incinerating the liquid residues, these are collected in the distillation chamber and transferred via a rotary cylinder and a chute into the burner chamber where they are then appropriately ignited via the burner flame. By contrast, the gaseous residues are fed to a long-period residence chamber which is a tube system having a length of 75 m and more. Heating rods or heating wires are pushed and inserted into the individual tubes of the tube system in such a way that the waste gases are heated in a controlled and continuous manner to the requisite temperature and then cooled again. The flue gases which have been appropriately cooled and freed of pollutants can then be released into the atmosphere. By means of the method and the spent oil reprocessing plant, it is possible effectively to reprocess even spent oils highly contaminated with pollutants and either to destroy the inevitably arising residues without polluting the environment or else to ... them in such a way ...

Inventor: BONGERS BERND
IPC: B60B17/00
Filed: 1988-04-28
Abstract: In order to achieve cost-effective production which is suitable for manufacturing in large series accompanied by high constructional rigidity of the wheel disc in a rail wheel (2) in which the wheel disc (6) which connects the wheel hub (4) to the tyre (8) of the wheel in a flexurally stiff manner is constructed using the fibre-composite method from two external fibre-composite cover layers (10) and an inner core (12) which is arranged between the said cover layers (10) in a shearing force-transmitting fashion and has a smaller relative density, according to the invention the inner core contains five fibre-composite struts (22) which connect the cover layers to one another and have a uni-directional orientation of the fibres in the longitudinal direction of the struts, which struts (22) extend in an alternating diagonal fashion through the inner core from the wheel tyre-side edge region of one cover layer to the upper-side edge region of the respective other cover layer and are provided at the end sides with bent-over connecting tabs (24, 26) which are bonded in a planar fashion to the respective cover layer and are supported on the hub or the tyre of the wheel. <IMAGE>
Patent DE-3827127-A1 (DE)
Title: Clutch
Inventor: SCHARFENBERG GUENTER
IPC: F16D13/64
Filed: 1988-08-10
Abstract: The invention relates to a clutch with a first, continuously rotating clutch flange 2 and a second clutch flange 4 to be driven which is axially displaceable relative to the first clutch flange. The faces of the two clutch flanges which come into contact are of novel design: the face of the first clutch flange is provided with sharp-edged, rib-like raised portions 8 which are arranged so as to run essentially radially, while the face of the other clutch flange is covered with a rubber mat or the like in order to achieve a particularly high friction coefficient. The particular advantage of a clutch of this kind is that it permits virtually slip-free start-up of the machine element to be driven after the engagement of the clutch (Fig. 1). <IMAGE>

Abstract: The scraper, according to the invention, for scraper chain conveyors is intended preferably for integration into the plate-link-chain belt of a curved conveyor and forms a structural unit together with the bridge links which connect the round-link-chain portions of the plate-link-chain belt at the scraper-installation point. The scraper (1) according to the invention is designed in two parts and is composed of a single-piece foot part (2) which extends over the entire scraper length and includes the scraper ends and of a head part (3) which can be seated, as a cover, on the foot part (2) from above, the length of which is smaller than the scraper length, and which can be supported, by means of its two ends, against projecting shoulder surfaces (9) of the foot part. The connection of the two scraper parts takes place, approximately in the scraper central plane, via longitudinal weld seams (11) and, in the region of the shoulder surfaces (9), via transverse weld seams (12). The two scraper parts (2, 3) together form a scraper cutout (4) in which the bridge links serving for the chain connection are connected to one another and to the scraper via bolt articulations and/or pin articulations to form a structural unit. <IMAGE>
