Title: Hydraulic clamping device to fasten machine part to shaft - has pressure generator of sleeve, screwed coaxially to housing, both forming pressure chamber and ring groove
IPC: F16B31/04
Filed: 1992-02-13
Granted: 1993-08-19
Abstract: The device has a housing (1), screwed to the shaft. A pressure generator with a pressure chamber (10), contains an axially movable pressure piston. A ring piston (13) transmits a pressure to the machine part, which is held in a ring groove (12). There is a connection to transmit pressure from chamber to groove. The pressure generator is formed by a sleeve (2). This is coaxial to the housing, and screwed to it. Both enclose a ring-shaped recess, which forms pressure chamber and ring groove. The chamber is closed on one side by housing or sleeve, and executes an axial movement, when housing and sleeve are screwed relative to each other. USE/ADVANTAGE  - Hydraulic clamping device is smaller in radial and axial directions, has no projecting parts, has high clamping force, and simple construction.

Title: Sludge evaporation and drying assembly - has plate packets as evaporation surfaces for exposure to compressed steam in a pressure vessel
IPC: C02F1/04
Filed: 1992-03-12
Granted: 1993-07-29
Abstract: The assembly to evaporate and dry sludge, through vapour compression, has evaporation surfaces arranged horizontally and/or vertically within the evaporation housing, as plates assembled in plate packets. The separate plates are separated from each other by mechanical spreaders and scrapers, mounted to a drag chain. The sludge is distributed over the plates by a delivery system with feed control valves. A bucket wheel lock is at the base of the vessel, in a vacuum tight mounting, to extract the dried and evaporated sludge. USE/ADVANTAGE- The assembly is for drying and/or evaporating sludge, mainly composed of water, sand or similar inorganic solids and low volatile hydrocarbons as separate sludge components or component combinations of the sludge. It is typically used for oil sludges containing solids, in bitumen mfg. from tar sand, where water cannot be removed mechanically through the large particle sizes. The sludge can be dried economically and with low energy consumption
