Patent DE-4126624-A1 (DE)
Inventor: HAUPT ROBERT
IPC: H02J7/14
Filed: 1991-08-12
Abstract: The charging device proposed is intended particularly for accummulators (14) which supply the power for electropneumatic brake-control units (17) and/or anti-skid devices (18) on goods wagons. A reservoir (4), to which a pneumatic motor (8) is connected via a 2/2 way valve (6), is charged through a nozzle (3) from the air brake, in particular from the compressed-air reservoir (1), on the goods wagon. The pneumatic motor (8) acts as the drive unit for a generator (11) which charges the accummulator (14) through a regulator (13). The 2/2-way valve (6) is designed to switch in dependence on the pressure in the reservoir (4) such that it opens when a first reservoir pressure level is reached and closes when the reservoir pressure sinks to a second, lower, level. The charging device ensures intermittent runnning of the pneumatic motor (8) and a good compressed-air supply to the motor, the compressed-air flow drawn off the brake compressed-air reservoir (1) being only small and hence with no adverse effects on the brake system. The 2/2-way valve is controlled by the regulator (13) such that it cannot open when the accummulator (14) is fully charged. This measure avoids the pneumatic motor (8) working with the generator (11) in a no-load condition.

Title: Spinning machinery with flyers which can be driven faster - has a presser arm with paddle designed to avoid breaks and thin places
Inventor: STEINER HANS ULRICH
IPC: D01H7/32
Filed: 1991-11-14
Abstract: Machine comprises a presser paddle which feeds a slubbing on to the surface of a bobbin being wound on a flyer frame. The paddle is designed with a groove which gradually lays the slubbing on the surface of the bobbin, and is controlled by a short flange which tapers to the bobbin. The paddle is pref. shaped so that any pressure from the hollow flyer is directed against the slubbings already laid on the bobbin, and not on the slubbing still at the paddle. It may be constructed of plastic, ceramic or hard metal. The groove is in the form of an arc, initially contained within the flanges, but the flange gradually tapers on to the circumference of the windings of the bobbin, which are pressed by the surface. The slubbing is pref. laid tangentially on the bobbin, and the surface ensures that the newly laid slubbing is not being pressed by the paddle. The arc (26) in the groove for the slubbing is opt. variable. USE - The paddle must be on a balanced arm and lay the slubbing on the bobbin to create a tight package, without causing breaks of thin pieces. In the absence of pressure on the newly laid slubbing, the flyer can be driven faster.
