Patent DE-4016632-A1 (DE)
Inventor: KALBAS HANSWERNER ING
IPC: F15B15/26
Filed: 1990-05-23
Abstract: In the case of an actuating cylinder, particularly a double-acting door-lock cylinder for actuating doors of rail vehicles, a bolt mechanism is necessary, which with total reliability prevents opening of the doors when the train is in motion. For bolting the piston rod (3) of the actuating cylinder connected to the door locking mechanism and able to be actuated by a piston, a bolt (9), movable in a transverse direction of the piston rod (3), is provided, which is supported on both sides of the longitudinal axis of the piston rod (3) in guides of the housing (5) accommodating it, the piston rod passing through a bore of sufficient width running in the bolt (9) in a transverse direction to this. The bolt (9) can be actuated by compressed air against spring force, that is it can be shifted into its bolting position, the pressure acting on the bolt being monitored by a valve (15), which can be actuated by a section of the piston rod (3). In the locked position a shoulder (31) of the bolt (9) is in collision with the displacement travel of the piston rod, the withdrawal of which from the locking mechanism can thereby be prevented. <IMAGE>

Title: Installation for measuring weight of packed article - has pneumatic circuit which enables tare weight to be automatically checked
Inventor: KAUL DIETER
IPC: G01G5/00
Filed: 1991-07-26
Abstract: An installation for measuring the net weight of a packed article has a pneumatic control system which enables the tare weight to be checked. The weight of the article is counterbalanced by the pneumatic pressure on the piston (33) of a pneumatic cylinder. The pneumatic circuit is controlled by two valves which can be actuated by press buttons (T1, T2). Actuating one of the press buttons provides a pressure which balances the gross weight, whilst actuating the other button provides a reduced pressure which balances the net weight automatically. USE/ADVANTAGE - Pneumatic system for weighing articles. Checks the tare weight automatically.

Title: High purity argon recovery using simple and safe method - by purely cryogenic treatment of crude argon from air fractionation using liq. nitrogen@ to remove oxygen@ and nitrogen@
Inventor: WESTMEIER SIEGFRIED DR
IPC: F25J3/04
Filed: 1991-08-31
Abstract: High purity Ar is recovered from the crude Ar from an air fractionation plant by subjecting the crude Ar, withdrawn from the Lachmann stage of the upper column (1) of the double column of the air fractionation plant, to 50-98 % enrichment in a crude Ar column (3) and then to simultaneous O2 and N2 removal by a purely cryogenic process comprising (a) liquefying and then cooling with liq. N2 in a crystalliser (6) to 5-18 K below the m.pt. of pure Ar; (b) feeding the resulting liq-solids mixt. to a fractional crystallisation column (7); (c) passing the mixt. downwardly through the column (7) in counter-current to a liq. mixt. derived from crystals melted at the bottom of the column, so that part of the upflowing liq. crystallises onto the downflowing crystals, resulting in Ar enrichment on the crystals and Ar depletion in the upflowing liq; (d) withdrawing pure liq. Ar of the desired quality at the bottom of the column; and (e) returning the impure crude Ar from the top of the column (7) as liq. mixt. feed to the crude Ar column (3). ADVANTAGE - The process is simple and safe, has reduced costs and gives improved prod. quality.
Patent DE-4130337-A1 (DE)
Inventor: SCHILLING WILFRIED
IPC: G05D23/24
Filed: 1991-09-12
Abstract: A heating unit (1) for a hotplate has an outer heater (3) and an inner heater (4), which is located in said outer heater (3), for essentially separately heating in each case one associated area region (13, 14) of the overall heating surface (2). The two heaters (3, 4) can be controlled differently and, in this case, the power supplied, for example, is distributed to the two heaters (3, 4) such that it switches over periodically and alternates without any gap in very short, but variable time intervals. The switching-over takes place as the alternating-current characteristic passes through its zero line. In consequence, any desired power distribution can be achieved (without influencing a click rate) on at least two area regions (13, 14) of the same heating surface (2), and a high efficiency is achieved as well as matching to the respective heat consumption, with the aid of relatively simple control means (10). <IMAGE>
