Patent DE-19819077-A1 (DE)
Title: Spindle to carry yarn bobbins in a yarn dyeing apparatus
Inventor: TIGGES DIRK
IPC: D06B5/16
Filed: 1998-04-29
Abstract: The spindle (2) to carry bobbins, in a yarn dyeing apparatus, has a positive fit (14) system for the lock (12) holding the bobbin sleeves using spring force in the locking position.  The unlocking action is by a pull force, against the spring. The positive fit unit (14) is moved vertically upwards to release the lock (12).  The lock (12) has a recess (18) to take the positive fit unit (14), with a moving release (21) at it as part of the outer lock section (22).  An inner collar (23) grips under the positive fit (14). The positive fit unit (14) has a bolt across the longitudinal axis of the spindle (2), in two slits at the holder (18), open outwards. The slits form an acute angle with the verticals, and can be open upwards. The holder (18) is a section of a sleeve, with a thick wall. The positive fit unit (14) is clamped in the positive fit setting by a ring section (25) round the outer side of the holder (18). The holder (18) is moved up and down to release and lock the positive fit unit (14). The release can be through an inner section of the closure, as a bending plate component, in a downwards U-shaped profile, working with the holder (18) as a bending plate in an upwards U-shaped profile.  The inner bending plate of the lock has straight slits which partially cover the closed slits at the holder (18).  A cover is over the legs of the holder (18) profile.  The positive fit is clamped by the spring action of the inner closure section, and the spring force is applied between the cover and the upper side of the inner closure section. The closure (12) is released by an upwards pull action, and the spindle (2) is held at the base (34) by a ratchet lock (36), which engages a ratchet ring (30) at the spindle sleeve (5), which is released on a pull force.

Title: Tape retraction mechanism for signal recording and reproduction device
Inventor: YONEDA HARUHIKO
IPC: G11B15/43
Filed: 1998-05-18
Abstract: The arrangement includes drive devices for pulling the tape, and a drive lever (6),which is mounted pivoting at his base on a chassis (1), and revolves between a drive start position and a drive end position. A tape retraction lever (5) has an outer end which is equipped with a tape retraction pin (51). The tape retraction lever revolves between tape retraction start and end  positions, whereby a front end part of the drive lever (6) engages with the base of the retraction lever in a first step of a tape retraction movement, and transfers force to the tape retraction lever.  An auxiliary lever revolves between start and end positions, whereby a front end of the drive lever engages with a front end of the auxiliary lever (7) in a second step of the tape retraction movement, to transfer the force of the drive lever to the auxiliary lever. The auxiliary lever is provided with a pressure surface for pushing a middle part of the tape retraction lever, to move the tape retraction lever to the retraction end position.

Title: Process to remove impurities from liquid carbon dioxide generated by fermentation process by gravity separation
Inventor: BREYWISCH DIETER
IPC: C01B32/50
Filed: 1998-11-17
Abstract: A process extracts an oxygen-poor phase from liquid carbon dioxide which has been produced from a fermentation process. Incoming liquid carbon dioxide with the dissolved oxygen is released onto the surface of liquid carbon dioxide within a tank. The incoming liquid carbon dioxide is released in such a way as to minimize the turbulence in the incoming liquid. Non-turbulent carbon dioxide sinks to the bottom, leaving the impurities at or near the surface. Almost pure carbon dioxide is drained from the base of the tank. The liquid carbon dioxide is released into the tank via a baffle arrangement of steel wool.
