Patent DE-3923903-A1 (DE)
IPC: B65D83/36
Filed: 1989-07-19
Abstract: The invention concerns a process for filling pressurized-gas packs, as well as the pressurized-gas packs themselves which comprise a casing (1) containing a pressurizing agent and in which is located at least one flexible bag (2) designed to hold the liquid constituting the contents of the pack. The interior of the flexible bag (2) is closed off by a valve (6) located in the region of the mouth (4) of the casing (1). In order to improve the above-mentioned process and the associated pressurized-gas pack, so that not only any pressurizing agent, in particular air, but also commercially available casks can be used and the whole filling operation carried out in a relatively short time and hence with correspondingly less expenditure of resources, it is proposed that the flexible bag (2) is accommodated in the casing (1) in such a way that there is a gap (5) between the edge (3) of the bag opening and the mouth (4) of the casing (1), and the pressurizing agent is introduced through this gap (5). The edge (3) of the bag opening is hermetically closed off together with the mouth (4) of the casing (1) by the valve(6) which is actuated for the interior of the bag (2) to be evacuated and actuated again for the contents to be introduced into the bag (2). The interior of the bag (2) is evacuated by connecting it to a vacuum. The bag (2) is designed as a gusset bag with the gussets facing inwards.

Patent DE-4012138-A1 (DE)
Inventor: MEISE BRUNO
IPC: A47L15/50
Filed: 1990-04-14
Abstract: In a process for cleaning and drying respiration tubes (4) in a programmed laboratory dishwasher, the respiration tubes (4) are deposited, rising in circular or helical fashion along their length, on a supporting frame which is designed as an insertion rack (1), the cleaning or rinsing liquid and the drying air in the respective programme stages being delivered to the respiration tubes from one end, rising upwards from the bottom. The insertion rack (1) has for this purpose a supporting frame for the respiration tubes, which frame has one or more downwardly directed tube-stacking elements (3) arranged in spiral or helical fashion. The process guarantees a one hundred per cent internal rinsing and consequently also an internal cleaning of the respiration tubes since, during the rinsing procedure, a rinsing water column builds up in the respiration tube, which column flows through the respiration tube from bottom to top, regardless of the length of the tube, and also thoroughly rinses out the tube folds. The drying air in the respiration tube acts in a similar way. <IMAGE>

Patent DE-4038014-A1 (DE)
Inventor: BRACHERT THOMAS DIPL ING
IPC: F16L23/028
Filed: 1990-11-29
Abstract: These pipes are used to convey hot gases, especially exhaust gases from an internal combustion engine driving a motor vehicle. In this application an exhaust manifold is secured to a cylinder head by a first securing flange, whereby the free side of the manifold has a second securing flange which is connected to an exhaust pipe via another securing flange. The exhaust manifold and the exhaust pipe interact via a spherical seal in order to compensate tolerances in the entire exhaust system. Here the second securing flange is a flange component made separately from the exhaust manifold which is positively supported on an annular component. The annular component is axially tensioned against a shoulder on the exhaust manifold. This design takes account of high bending stresses acting on the second securing flange.
