Title: Hydraulic swivel draw table clamp for press tool - has clamping head turned through 90 degrees in T=slot by co=axial rod with fast spiral section sliding through nut
Inventor: MATZAT HENDRIC DR ING
IPC: B25B5/06
Filed: 1991-05-02
Abstract: The swivel-draw type table clamp is sunk into the machine table to present a clear surface when the bar-shaped clamping head (8) is withdrawn from the tool T-slot into the pocket (12). Inside the cylindrical housing (1-3) is a rotatable rod (7) with piston (9) at the top, a fast spiral section guided through a nut (10), and a square or hexagon section (14) sliding through a matching bore in a rotatable draw plunger with a piston (11) at the top and clamping head (8) at the bottom. When the spiral section slides through the nut, the rod turns through 90 degrees taking with it the draw plunger and clamping head, thus allowing the head to enter or escape from the T-slot. Hydraulic oil can be sequentially admitted to pressure chamber (4-6) to extend or retract the draw plunger, to rotate the clamping head by axial movement of rod (7), and to apply a clamping force. ADVANTAGE - Compact dimensions.

Inventor: THOME ROLAND DR
IPC: C01F7/441
Filed: 1991-06-06
Abstract: 1. Partially crystalline transition aluminium oxides, process for their preparation and use thereof for the production of mouldings essentially comprising gamma-Al2O3. 2.1 The decomposition products obtained by the known processes still contain crystalline fractions of undecomposed aluminium trihydroxide, especially of hydrargillite and/or fractions of hydrothermally produced boehmite, and as a result the required solid state reactivity is not always achieved. 2.2 The object is to produce partially crystalline transition aluminium oxides, which have a uniform phase composition and a high solid state reactivity, and which in the rehydration process even at atmospheric pressure make it possible to achieve a high degree of conversion of the solids particles into a finely fibrous boehmite, so as to ensure efficient further processing to give mouldings, which essentially comprise gamma-Al2O3 and which have a well developed internal surface and high mechanical stability. The partially crystalline transition aluminium oxide is characterised in that the solid, in addition to aluminium having coordination numbers of 4 and 6 also comprises aluminium with a coordination number of 5 vis-à-vis oxygen, the proportion of aluminium with a coordination number of 5 comprising at least 50% of the content of aluminium with a coordination number of 4. 2.3 The Al2O3 mouldings produced by the process according to the invention are suitable for the use as adsorbents, gas purification compositions, catalyst components or catalyst supports.
