Title: Table supported on telescopically and non-telescopically operated columns - has lever operated brake with wedge extension, base guide flange, pipes and plates
Inventor: SAUTHOFF JUERGEN
IPC: A47B9/20
Filed: 1991-06-15
Abstract: The table is supported by columns (1) containing lifting-units (H) for telescopically extending the rigidly connected columns not possessing lifting-units. The telescopically-extended position is locked by a brake (B) operated by a lever (7) which moves the accumulator housing (8) to and from. The brake has a wedge-extension (9) preferably shaped as a four-sided truncated pyramid, the base of which forms a supporting guide-flange (19) for the inner pipe (3). The brake-main parts (10) are in the form of facing brake-blocks possessing plates (11) in the space (y) between the inner and outer pipes (3, 5). Support-feet (17) fit through holes (15) in the inner pipe walls and rest on two facing outer surfaces of the truncated-pyramid. ADVANTAGE - The table rests on several columns with those columns not containing accumulator-lifting-units being braked synchronously.

Title: Debye balance determn. of thermal conduction in gases - applying thermodynamic model to thermal and potential energies of mols. of airflow in acceleration field
Inventor: BSCHORR OSKAR DR RER NAT
IPC: G01N25/18
Filed: 1991-06-19
Abstract: The corpuscular transfer of heat in gas within a gravitational or similar field is investigated theoretically. With the application of the Debye balance calculation it appears that an externally imposed acceleration vector has no effect on the coeffts. of thermal conduction, but induces a thermodynamic temp. gradient given by the quotient of this vector and the specific heat (Cp) at constant pressure. In a column of air subject to the acceleration due to gravity (g), this effect causes a decrease in temp. of 9.7 K per km of altitude.

Title: Mechanically or hydraulically actuated workpiece table clamp - has U=shaped spring clip seated in groove around height adjusting nut and having fork ends of clip supporting clamping strap to prevent dropping
Inventor: SCHOEN HANS
IPC: B25B5/16
Filed: 1992-02-20
Abstract: The clamping strap (3') can be forced downwards to clamp the workpiece (1) on to the table (2) by tightening the nut (17) or actuating the hydraulic cylinder (24) to exert an upwards force on the clamping strip through the height adjusting nut (8). To prevent the strap (3') from dropping when the clamp is released and the work is removed, a U-shaped spring wire clip (13) is seated in a circumferential groove (11) of the height adjusting nut with the fork ends of the clip bearing against the underside of the clamping strap. The spring clip exerts an upwards force supporting the weight of the clamping strap, but as well the frictional grip of the clip in the groove (11) prevents unwanted rotation of the height adjusting nut (8). USE/ADVANTAGE - Clamping strap is properly supported by clip irrespective of height adjustment. Simple, compact design with no loose parts.

Inventor: TORPEY PATRICK
IPC: B01D33/052
Filed: 1992-07-17
Abstract: Sewage sludge is dewatered by gravity on an endless filter belt 11 where it passes over a first filtrate tray 13, then a variable fraction of the sludge is removed by a first scraper 15 and diverted to a hopper 16 while the rest of the sludge is carried by the belt round a pressing roller 23 before being removed by second scraper 18 to the hopper 16. The scraper 15 is adjustable, so that the overall solids content of the mixed sludges obtained from hopper 16 may be controlled. The mixture viscosity may be monitored and scraper 15 automatically controlled to maintain its constant. Scraper 15 may comprise a single bowed and flexible blade or a series of separate blades individually movable relative to the belt. Thus most of the sludge remaining on the belt is near its centre, to counteract the lateral squeezing where the belt goes round roller 23. Roller 23 may be grooved. Filtrate from tray 14 is used to backwash the belt downstream of the pressing stage, and the resulting mixture is separated by gravity. <IMAGE>
