Title: Sliver can return - checks for remaining material to be emptied before the can is refilled
Inventor: TEICHMANN PAUL DIPL ING
IPC: D01H9/18
Filed: 1991-03-23
Abstract: The sliver cans, which are removed from workstations where their sliver contents have been consumed, are passed through a can emptying station before refilled with sliver.

IPC: B21B1/18
Filed: 1991-04-18
Abstract: 2.1. Rolling is carried out up to a delivery cross-section of 900 mm<2> < A < 15,700 mm<2> on ungrooved rolls and before the transition to the sectional grooves, depending on material quality and the number of flat passes in one or two slightly indented grooves, a notched groove being predetermined by the ratio of emerging rolling-stock height (h1) to twice the turned-down depth (2t) of the roll, and this ratio lying within the range 2 </= h1/2t </= 10. In this arrangement, a 4-roller mounting is arranged on the entry side in the 1st roll stand during flattening and a double mounting is arranged in the subsequent roll stands, whereas on the exit side a stripper is provided. 2.2. The problem on which the invention is based is to simplify the division of the rolls and mountings and, by defined dimensioning of the first sectional groove, to eliminate the influence of the sharp edges from the last flat pass on the wear, and also to limit the diagonal distortion of the rolling stock. 2.3.

Title: Window for aircraft cabin - has two panes which can be pressed together to vary area covered by opaque liquid
Inventor: MUELLER HANS-JUERGEN
IPC: B64C1/14
Filed: 1991-05-18
Abstract: The window is provided with a system to regulate its transparency. The window (1) has two panes arranged almost parallel to each other with the gap (4) between the two panes increasing from a minimum at the lower edges to a maximum at the upper edges.

Title: Time switch for pressure medium system - has constant independent timing, independent of pressure, etc.
Inventor: HOFMANN KARL DIPL ING
IPC: F02M45/08
Filed: 1991-06-29
Abstract: The valve has a valve member and this slides in a housing with connections for a pressure source and a consumer.
