Patent DE-19918501-A1 (DE)
Inventor: BOESL THEODOR
IPC: F16D48/02
Filed: 1999-04-23
Abstract: A hydraulic system for a power-take-off in a utility vehicle is described, having a pump (8) supplying hydraulic fluid to the clutch (1), the brake (2) and a lubricating circuit, a control valve for engaging and releasing the clutch and a device containing a pressure-limiting valve (12) which makes a high system pressure available when the clutch is engaged and a lower system pressure when the clutch is released. In order to keep loss of power in the pump as low as possible and reduce the number of components required in a hydraulic system of this type, the system pressures are controlled by the pressure applied to the engaged clutch. Consequently, the system pressures can be adjusted regardless of the design of control valve used. This means that less expensive 3/2-way valves or 3/2-control valves can be used. This also has an advantage in that different system pressures can be produced using a single pressure-limiting valve. The hydraulic system is suitable for all types of utility vehicle with a power-take-off. <IMAGE>

Title: Processing of waste materials, especially waste paper, involves sorting in a container with an upper and a lower grid, drying in warm air before dried matter drops to the base for removal
Inventor: MARTIN HARALD
IPC: F26B17/00
Filed: 1999-08-03
Abstract: For the disposal of waste, the wet waste material is placed in a container on an upper grid for stocking. Through the movements of the grid and/or the nature of the waste, the material passes through this grid onto a lower grid. The material rests on the lower grid in a warm air environment where it dries and drops through the grid spontaneously and/or through grid movements to be finally removed from the bottom of the container. The warm air flow is partially upwards but mostly downwards for extraction at the base with the dried waste.  The waste and rubbish fed into the container has a residual moisture content of 40-50%, and it is stored on the first grid to reduce the moisture content to 20-30%. At least one grid, and preferably both of the grids is on a mobile mounting, to give a dosed delivery of the waste matter to the lower grid. The upwards flow of warm air loosens the material on the second grid, to reduce it for dropping through the grid to the bottom of the container for removal. The warm air is used in the container at a pressure of 2-3 kPa, and the exhaust warm air is filtered on leaving the container.  An Independent claim is included for a waste disposal assembly with an upright cylindrical container to take in the waste at the top, where processed waste is removed at the bottom. The container has two grids, at different levels, and has a warm air feed system.
