Title: Maintenance method for working section of textile machine uses thread positioned by suction device, and increases retaining friction on thread during cutting process
Inventor: BRANDL SEBASTIAN
IPC: B65H65/00
Filed: 2003-12-17
Abstract: The method uses a thread, which is placed on a coiling device by a suction tube (20) connected to a vacuum source (97), and moved to a thread cutter. The retaining force is increased by friction, and this is generated by wrapping the thread around one or more bodies in a helix shape. The deflection body is formed by a helix-shaped vacuum hose (202) with roughened surface. The friction coefficient between the thread and its contact on the hose is sufficient to hold the thread securely for cutting. To increase retaining force during cutting, a regulator device (9) increases the volume flow generated by the vacuum.

Title: Stabilised adsorption air filter without binder on surface
Inventor: BETZ HARALD DIPL ING
IPC: B01J20/28
Filed: 1995-04-22
Abstract: Adsorption air filter (as in DE P 4442713.1) consists of a self-supporting moulding of (ir)regular adsorber particles with an average size of 100-7000 mu m and smaller binder particles with a lower m.pt.. The distribution of the adsorber and binder particles is irregular, so that no agglomerate structure is discernible with the naked eye; and the binder material does not spread onto the adsorber surface below 100 deg C. The novelty is that the absorber particles are completely enclosed in a frame which is not penetrated by the particles and is in direct contact with the particles, without an intervening adhesive layer. Also claimed is a method for making the filter.

Patent DE-19521830-A1 (DE)
Inventor: DANIEL EDWARD A
IPC: F16F15/315
Filed: 1995-06-16
Abstract: A hydrostatic/hydrodynamic flywheel bearing assembly for a press includes a flywheel (36) mounted for rotation about a non-rotating quill (42). A bronze bushing (54) is disposed between the quill and flywheel. Hydrostatic pad areas (60) are located on the quill opposite the bushing. These pad areas are flooded with pressurized oil or liquid to create a hydrostatic bearing area. During operation, flywheel and bearing rotation cause a hydrodynamic bearing effect to occur. The hydrostatic/hydrodynamic bearing eliminates the need for conventional rolling bearings, provides indefinitely long life with full-film lubrication, high shock load capacity, high vibration damping, and a high value of radial and tipping stiffness. <IMAGE>
