Patent DE-4210009-A1 (DE)
Inventor: BECKER WILLI
IPC: F16L39/04
Filed: 1992-03-27
Abstract: A turnable connection for feeding a suction medium and/or a pressure medium to a rotatably mounted part, in particular to a cylinder of a printing machine, having a stator and a rotor belonging to the rotatable part, the stator and rotor being sealed off relative to one another during the feeding of the medium, which is possible in the stationary state irrespective of the angular position of rotation of the rotor, via sealing elements which interact with counter-sealing elements for coupling at least one medium connection path. Provision is made for the stator (3) and the rotor (4) to be mounted so as to be axially displaceable relative to one another (which means in the direction of the axis of rotation 12 of the part 2 or of the rotor 4) from a first position into a second position, in the first position the sealing elements (43) resting against the counter-sealing elements (48) and, in the second position, there being a spacing between the sealing elements (43) and the counter-sealing elements (48). <IMAGE>

Title: Opening and mixing textile fibres - using a monitored feedback system to switch wales in a continuous system to maintain standards
Inventor: SCHLICHTER STEFAN DIPL ING DR
IPC: D01G7/08
Filed: 1992-04-24
Abstract: The process extracts and mixes textile fibres, e.g. cotton or synthetics, from bales of different origin. Gps. of different but pre-determined characteristics are assembled in a manner which allows additional but regulated variation from other bales with similar pre-determined characteristics. Pref. the system commences with at least one bale opener after the banding is removed, and which cuts the face of a bale at an angle. The blades of the machine rise and fall to produce tufts of fibre from the bale, which are then extracted by air suction, and fed into a mixer. This also includes a cleaner. The bales are held in a storage system (16) which is arranged to have some method of transport, such as a conveyor band or lattice, with the facility to alternate the bales of different origin or characteristics, but within the group of fibres required for the process. An overall control is connected by sensors and electronic circuitry, so that initial parameters are recorded. These are then compared in the monitor with the prod. information fed back from the mixer, cleaner, card, drawframe and the spinning frame. ADVANTAGE - The process is suitable for manual sampling feedback along a continuous system from bale to yarn. It may also be adapted to semi-automatic or a fully on-line automatic system with electronic monitoring. The process avoids machinery standing idle.

Inventor: KESSLER REINHARD
IPC: B65D39/00
Filed: 1992-07-29
Abstract: An elastic plastic bottle stopper is in two parts arranged axially with a thin layer of material impervious to gases lying transversely between them. This layer is pref. a film of ethylene-vinyl alcohol copolymer coated on both sides with polyethylene. The example, shown has the top (2) and bottom (3) parts sepd. by a thin impervious film (4) of the pref. polymer with polyethylene coating, and of total thickness 0.1mm.

The stopper is basically cylindrical but with a slight attenuation at the inner end (70) and at the base  (5) of the topmost shoulder (80). The stopper thus fits into the bottle neck to withstand an internal pressure of e.g, 1-2 bar. It is suitable for sparkling wines as a result. ADVANTAGE - The stopper has the deg. of imperviousness to gases which is required (e.g, for wine bottles etc.). It is made of inexpensive elastic material. Its polyethylene coating minimises its water absorption.

Title: Nursing shirt, vest for breast-feeding mothers
Inventor: MOTHES ULLA
IPC: A41D1/215
Filed: 1993-07-16
Abstract: The nursing shirt (vest, body, night shirt) allows a breast-feeding mother to offer her breast to the baby without having to push up her clothing. It contains compartments for breast pads. It can supplement or replace the nursing brassière. The nursing shirt serves as underwear which is warming or has a very low neckline or as nightclothes for breast-feeding or pregnant women. The breast sections of the shirt can be opened up individually by means of fitted-on breast parts. These are attached on the front part along the lower rounding of the breast. The breast parts can be unbuttoned from the centre to just at the height of the nipples. The front part ends a few centimetres above the lower rounding of the breast, so that the breast parts overlap it and compartments for breast pads are thus produced.

Title: Wood and lignite tar conversion
Inventor: GEIER-HENNINGER KURT
IPC: C05D3/00
Filed: 1993-07-27
Abstract: For the chemical conversion of wood and lignite tars, they are dissolved in an alkali water.Catch vessels (4), with ring rinsing of treated water through water feed (7), trap tar droplets or tar flow. The mixt. of tar particles and water is returned to the mixing container by a suction/mixing pump(19).

Title: System for equalising torque during ratio change of automatic gearbox - has sensors for establishing torque before and after change for comparison with stored characteristics related to main vehicle parameters
Inventor: SHIRAISHI TAKASHI
IPC: F02D41/04
Filed: 1993-10-13
Abstract: The system for matching a change in torque which otherwise occurs at each ratio change of an automatic gearbox (12) fitted to an IC engine (11) uses an engine torque control unit (10) and a gearbox ratio controller/actuator (7). Sensors are used to establish the instantaneous torque immediately before and after the ratio change.
