Title: Liquid-liquid extraction tower - comprising vertically spaced cross flow trays and constant flow rate maintaining baffle arrangements
Inventor: BUSHNELL JAMES D
IPC: B01D11/04
Filed: 1975-06-06
Abstract: A liquid-liquid extraction tower comprises vertically spaced cross-flow trays and baffle arrangement whereby constant flow rate is maintained between the trays and whereby the inter-tray spacing is split into dispersion and settling zones. The tower is used particularly in extracting aromatics from hydrocarbons using phenol solvent. The flow rate of the rising separated light phase is maintained constant irrespective of feed rates and the separated phase is prevented from re-mixing with the falling heavy phase. Coalescing time is decreased.

Title: Bevelling machine for flanged cylindrical workpieces - with automatic feed and simplified tool holder arrangement
Inventor: MOELTZNER WILHELM
IPC: B23B5/16
Filed: 1975-11-14
Abstract: Device for bevelling, sharpening or similarly treating cylindrical workpieces with a head or flange is described. A rotating table is situated coaxially w.r.t. the tool and on this table are mounted workpiece holders composed of the elements of the workpiece holders and spindles. These are arranged with their axes parallel to the axis of the rotating table and movable w.r.t. the tool mounted in a frame below the table, with a cooperating ring attached to the frame for guiding the workpieces and with a drive plate rotating with the table and provided with grooves into which the workpiece shafts fit. The upper surface of the cooperating ring guides the heads of the workpieces, the shafts of which are guided into the groove of the drive plate, the length of the internal surface of the cooperating ring. The upper surface of the cooperating ring has, between the introduction and removal positions of the workpieces, >=1 surface inclined in the direction of the motion of the workpieces guided by the rotating table, for an automatic feed of the workpieces towards the tool. The feed of the workpiece is automatic since it is guided by the cooperating ring. The inclined surface of the ring allows the workpiece to move the exact distance towards the tool. The arrangement of tool holders is also simplified.

Title: Multi-unit gas filter with reverse jet blowback - with valves allowing blowback fan to put suction on filter elements after cleaning
Inventor: MARGRAF ADOLF DIPL ING
IPC: B01D46/00
Filed: 1976-04-15
Abstract: The blowback air fan of a filter installation has valves on suction and delivery so that it may either draw in atmospheric air and deliver to the blowback duct, or alternatively suck from the blowback duct and deliver into the clean gas outlet. Use for multi-unit sock or bag filters for cleaning dusty gases, and which have reverse air jet element cleaning systems. During the reverse-jet cleaning cycle the sock element being cleaned is ballooned out away from its internal support cage, and only returns to its normal position on the support by reason of the gas pressure difference is small. The blowback fan places additional suction on the interior of a cleaned element and thus speeds up return to normal position. The overall filter operating cycle is thus speeded up.

The rotor tubes can be extended beyond the heater shell to pass thro. A refrigerator shell in which the prod. is cooled without being transferred from the tubes; this eliminates costly transfer conveyors which tend to damage the prod.

Title: Temp. compensation circuit for transducers - uses three inverting amplifiers with thermistor in feedback circuit of first amplifier
Inventor: STENZEL WERNER DIPL ING
IPC: G01D3/036
Filed: 1976-11-17
Abstract: The temperature compensation circuit for measuring transducers provides continuously adjustable compensation over a wide range for linearisation of the transducer characteristic. The circuit comprises an inverting amplifier (1) with its feedback loop containing a thermistor (R5). The thermistor responds to the temperature obtaining at the installation position of the transducer. The output of the amplifier is taken to a second inverting amplifier (2) which provides an output signal (U2) which is the difference between the temperature-dependent signal from the transducer (Ue) and the output of the first amplifier. The second amplifier's output can be tapped off a potentiometer (R10) and fed to a third inverting amplifier (3). The output of the third amplifier can thus be adjusted so that it is exactly compensated for temperature effects.
