Patent DE-2917505-A1 (DE)
Title: Ethylene sepn. from gas-stream contg. hydrogen and methane - by rectifying with reflux prodn. by multistep partial condensn.
Inventor: WALZL ROLAND DIPL ING
IPC: F25J3/06
Filed: 1979-04-30
Abstract: In separating a IC fraction from an H2-, CH4- and C2H4-contg. gas stream under pressure by rectification, the gas stream is pre-dissociated by cooling into an H2- and CH4-enriched gaseous fraction and a C2H4-enriched condensate. The reflux for a rectifying column is produced by the partial condensn. of the gaseous fraction with the simultaneous recovery of an H2-rich fraction. Novelty consists in producing the reflux by a multi-step, pref. 2-step, partial condensn, and feeding the condensates formed, at least partly, at different positions of the rectifying column. C2H4 losses at rectifying column head are reduced, e.g. from 0.7-1 vol% to 0.1 vol%, Energy consumption is also saved by feeding part of the rectifying column reflux at a temp higher than in a 1-step process.

Title: Switching arrangement for alarm circuit monitored by quiescent current - has terminal resistance at indicator circuits and polarised diodes w.r.t. supply current
Inventor: GORKA WILFRIED DIPL ING
IPC: G08B29/06
Filed: 1979-06-13
Abstract: The annunciator circuit is fed from the supply voltage (U1) and is provided with a terminal resistance (EW). Between the circuit feeds (ML) are the individual annunciators (M1) to (Mn), which can be ionization indicators.

This current increase can be sensed in the evaluator (AW) and this can actuate an alarm signal in the central control. A current change due to short circuit, or open circuit can also be sensed and indicated. The diodes (Dil) to (Din) are polarized for the current direction from supply source (U1), the voltage (U0) being of opposite polarity, or lower than the diode voltage.

Inventor: REDLICH HORST
IPC: G11B23/44
Filed: 1980-04-25
Abstract: The high density storage technique disc replay unit is used for frequency modulated and PCM sound recorded signals. Without interfering with the recorded sound signal additional information can be stored on the disc which is replayed as video text on a conventional TV set. A rotating disc (2) is tracked by a head (3) which provides an audio output (4,5,7,8,9) to stereo replay equipment and additionally, video text (11) in a form which can be displayed on a TV set (14). The video text signal (12) modulates a carrier which the TV monitor will accept and may be in PCM or FM form. The TV monitor (14) would normally use an antenna (15) for off-air reception and have changeover facility to receive the disc information. The disc information, i.e. video text, may be informative about the stereo work being heard. The supplementary information (12) is accompanied by indicator signals which a decoder (10) can recognise and use to power (Us) an indicator lamp so warning the user that the disc carries supplementary information.

Title: Thread monitor, esp. for sewing machine - with brake mounted on vertical path, upper end of path having movable limit stop and brake being loaded so it drops on thread breakage
Inventor: MOTZKE HANS-GEORG
IPC: D05B51/00
Filed: 1980-12-18
Abstract: A thread monitor, partic. for a sewing machine, incorporates a brake (26) mounted on the path (32) of a vertically -moving component. The path's upper end has a limit stop (38) for the brake (26), which can move to give an increasing gap between the limit stop and the thread roller (18). The thread brake (26) is loaded by a weight (34) so that it drops on a thread break. Typically, a curved slit (32) provides the path for the brake, with its free end further from the thread roller (18) than the end with the limit stop (38). A pivoting arm (34) on an upper horizontal axis (36) acts as the weight, with its free end carrying the thread brake (26), with the centre of arc of the slit (32) lying on the pivoting axis (36). The horizontal axis (30) supporting the brake plate of the brake (26) is secured vertically to the pivoting arm (34) and engaged by the guide slit (32), so that the arm and the brake are on opposite sides of the component (10) with the guide slit. There is a rapid reaction in the event of a thread breakage.

The distance between the supporting bearings, measured in the feed direction, is selected to be sufficiently small that the centre of gravity of the movable machine element, as viewed in the feed direction, is always arranged between each two load-bearing supporting bearings. The sliding/displaceable machine element is in turn supported via sliding-bearing supports at the respective guide cylinder and is provided with driving members which act on the latter and via which the feed movement of the machine element is transmitted to the guide cylinder.
