摘要： To decrease mechanical loading on the roller thrust bearings in hydraulic pressure fluid apparatus, a hydrostatic axial slide bearing is provided, having a rotating part with an axially directed face secured to the rotating elements of the apparatus; and a stator part, formed as an axially movable element, such as a piston, within a cylinder which has pressure fluid applied thereto from a pressure fluid tap of the apparatus, the piston being formed with an opening, preferably including a choke, through which pressure fluid is applied in the region between the piston and the axially facing surface of the rotor element, to provide a counterforce against the mechanical force exerted against the thrust bearing.

摘要： A gear rack arrangement for the track of an overhead conveyor system in which the movement of the transport unit is undertaken through the agency of a gear rack and pinion drive. The drive pinion of the transport unit meshes with the gear rack arranged at the track. According to an important aspect of the invention, the teeth of the gear rack are designed such that their thickness radially reduces inwardly and outwardly at the track curves, the plane of which is situated parallel to the plane of the gear rack.

摘要： A novel relief valve is disclosed of the type including a spring-loaded valve plate or disc and a valve seat. The valve disc is constructed so as to include a cylindrical guide on the discharge side thereof, the cylindrical guide and valve disc forming a piston enclosed within a cylindrical cavity in which the valve spring is inserted. The cylindrical cavity communicates with the valve seat opening by means of a bore opening into the facing side of the valve disc. In this manner, pressure that is present in the valve seat opening is transferred into the cylindrical cavity thus creating a control pressure differential related to the difference in areas between the valve seat and the piston formed. The spring thus need be dimensioned only for a partial area of the valve seat opening. The construction provides the advantage that the valve disc stroke-blowoff or discharge quantity characteristic is such that the seating pressure can be varied to any desirable extent in dependence upon the stroke.

摘要： A novel process is disclosed for the transfer of heat and/or matter between two or more gaseous or liquid agents, the process utilizing a carrier substance continuously circulated in closed cycle successively through at least two working spaces wherein heat and/or mater is respectively taken up and yielded. The carrier substance is present in a thin layer and the agents are caused to flow across the layer of carrier substance at both working spaces. Novel mechanical assemblies for the performance of said process are also disclosed herein.

摘要： There is disclosed a method and apparatus for cooling slag emanating from a combustion furnace operating with wet slag removal, wherein the slag is permitted to fall into the water bath of a slag removal device through the agency of a slag drop shaft which is closed at all sides about its periphery, the slag drop shaft being disposed between the combustion compartment of the furnace and the water bath of the slag removal device. According to an important aspect of the invention, the slag is periodically restrained and dammed up in the slag drop shaft along its fall path from the discharge end of the combustion grate into the water bath of the slag removal device, and further, this slag is sprayed with water and quenched within the slag drop shaft.

摘要： For ease of casting and replacement of combustion grates, particularly for use in incinerator structures, the combustion grate plates and support blocks are made as single integral structural units, for example signal castings, the units being placed on grate beams which may be both stationary, or selectively, movable, and retained on the beams by their own weight and by matching inter-engaging shaped seats, for example grooves or rectangular beams with retaining rails against which the beams fit.
