A protective housing is provided for electrical rails and the like, namely, reaction (secondary) rails and slide pick-up lines for operating electro linear propulsion motors for monorail vehicles. The new and improved housing is of simplified construction and enables comparatively large protective plate members to be assembled in the form of a tight housing on elevated monorail structures. The protective plates may be readily removed and slidingly displaced to expose the normally protected electrical components for maintenance, replacement or repair.

A plurality of longitudinally extending straight and curved, slide segments, the upper ends of consecutive ones of which are overlapped by the lower ends of the preceding segment to define a continuous, sledding run having a predetermined configuration, including straight and curved portions. Each segment is of generally trough-like configuration and has a cross-sectional configuration comprising a shallow, concave central sled-supporting portion terminating in convex side rail portions. The convex side rail portions have a generally inverted U-shape cross section with depending flanges extending integrally and downwardly from the outer portion thereof. Butt straps removably fastened to the depending flanges interconnect each slide segment to an underlying support. The underlying supports consist of universally mounted and adjustable struts each having a tube-shaped rail insertable in the inverted U-shape of the slide rail portions. Only one strut on each side of a slide segment at one end thereof is necessary. A plurality of spaced apart ground supports are positioned along the run supporting the universal mounts of the struts. Cables having turnbuckles extend between each ground support and the next succeeding strut downhill thereof. A ski lift may extend between the ends of the run.

A swashplate-type pivot bearing, or an axial piston machine that has the swashplate-type pivot bearing, which ensure reliable operation. The swashplate-type pivot bearing for a hydraulic axial piston machine has a housing section, a swashplate section and a multiplicity of rolling bodies. The swashplate section is pivotably mounted in the housing section by the rolling bodies and the rolling bodies are arranged in a full-roller configuration and/or without a cage in at least one rolling body row. The swashplate-type pivot bearing also has at least one follow-up device for follow-up adjustment and/or synchronization of the rolling bodies, which is arranged and/or formed at an end of the rolling body row. The follow-up device is controlled by a slotted guide.

Method for cooling flat plastic products, in which plasticized plastic compound is fed to a calender via a slot nozzle by means of an extruder and is rolled and calibrated to the desired shape in this calender between at least two smoothing rolls, after which the film or sheet produced in this way is fed to a chill section comprising a plurality of adjustable rolls and passes through this section until it is sufficiently cool and dimensionally stable, at least both the gap width between the rolls and the speed of the rolls being controllable by open- and/or closed-loop control.The degree of wrap of the flat plastic product around the respective roll is varied by adjusting the rolls in the chill section into a mutually offset arrangement, hence increasing or minimizing the cooling capacity.

The invention relates to the use of an agent that contains 5 to 99.9% in weight of carbamide and/or at least a derivative thereof, as a cleaning agent for closed systems, in particular as a dishwasher detergent, as a laundry detergent for washing machines, as an agent for cleaning, sanitizing and/or disinfecting for equipment in the food processing industry and for medical equipment, the use as a hand dishwashing detergent or sanitary cleaner or as a hand cleaner. In addition, the invention relates to a method for reducing or avoiding enzymes in cleaning agents for closed systems, in hand dishwashing detergents or in sanitary cleaning agents as well as an enzyme-free dishwashing detergent or enzyme-free sanitary cleaning agent that contain 5 to 99.9% in weight of carbamides or derivates thereof. Finally, the invention relates to the use of percarbamide as a bleaching agent in particular in dishwashing detergents and in sanitary toilet cleaning agents.

Method for cooling flat plastic products, in which plasticized plastic compound is fed to a calender via a slot nozzle by means of an extruder and is rolled and calibrated to the desired shape in this calender between at least two smoothing rolls, after which the film or sheet produced in this way is fed to a chill section comprising a plurality of adjustable rolls and passes through this section until it is sufficiently cool and dimensionally stable, at least both the gap width between the rolls and the speed of the rolls being controllable by open- and/or closed-loop control.According to the invention, the degree of wrap of the flat plastic product around the respective roll is varied by adjusting the rolls in the chill section into a mutually offset arrangement, hence increasing or minimizing the cooling capacity, the gap width, once specified, being held constant during each adjustment operation by means of an appropriate control system.

A combination load lock apparatus is provided, wherein a chamber is coupled to two or more valves in selective fluid communication with two or more respective volumes. A support member for supporting a workpiece is disposed within an interior portion of the chamber, wherein a translation apparatus is operably coupled thereto. The translation apparatus is operable to rotate and/or translate the workpiece on the support member about and/or along a first axis, wherein a detection apparatus associated with the chamber is operable to detect one or more characteristics of the workpiece during the rotation and/or translation thereof. The workpiece may be further rotated in a predetermined manner based on the one or more detected characteristics. A recess is further defined in the interior portion of the chamber, wherein the translation apparatus is operable to translate the workpiece into and out of the recess to reduce particulate contamination thereon.
