Patent DE-3927797-A1 (DE)
IPC: G09B21/00
Filed: 1989-08-23
Abstract: The invention relates to an intra-aural hearing aid for the deaf or hard of hearing with an earpiece which contains a microphone, an amplifier, an earphone, a battery compartment with battery and a balancing channel leading from the inside to the outside, closed off by a cover plate.

This section (2A) is joined by another (2B) which continues past the earphone (5) towards the cover plate (3) and is at least partially an integral component of a unit (6) containing the earphone (5) and at the same time forms the transition between the two sections (2A, 2B) of the balancing channel.
Patent DE-3929158-A1 (DE)
Inventor: GRUBE ERWIN
IPC: B65G47/66
Filed: 1989-09-02
Abstract: The invention relates to a conveyor which can be used as both an accumulating conveyor (33) for accumulating goods suspended on hangers, in particular pieces of clothing, and a storage or slope conveyor (22), and is characterised in that a traction mechanism (2) revolving in the transport direction takes hold of the hanger hooks (1) at their tip (1a) and the transport of the hangers takes place outside the region of their centre of gravity (1b). 
<??>As a result, both the charging point and the delivery point can be designed functionally reliably. As the traction mechanism, which is designed as a toothed belt (2) can be supported or stayed at any point without impairing or limiting the transport capacity, the accumulating conveyor (33) thus designed can be of any length. A guide strip (3), which runs parallel to the direction of transport and is formed on the basic body (5) of the conveyor, guarantees that the hangers transported cannot swivel and thus slip out of the conveyor. The useability is determined exclusively by the selection of the traction mechanism (2).

Title: Automatic bottle filling machine - uses inert gas at defined pressure to control flow of liq. into bottle
Inventor: BROLL ADALBERT
IPC: B67C3/10
Filed: 1990-06-11
Abstract: The bottle (2) is filled with an exact quantity of a liq.  The liq (1) is stored in an annular tank (3) and is subjected to the pressure of an inert gas (4).
