Title: Control of process operating speed e.g. for packaging plant - performing reduction in speed for required period while change in packaging material takes place
Inventor: BLEISCH GUENTER DR ING
IPC: B65B57/08
Filed: 1990-08-27
Abstract: The continuous production process, such as a packaging plant where items are processed on a continuous basis, has a facility to vary the processing speed while a change in packaging material takes place. The reduction is made such that a loss of quality is avoided.

Title: Ring spinner - uses sliver drawn to count of 0.3-0.8 to reduce the spinning process
Inventor: STAHLECKER FRITZ
IPC: D01H1/02
Filed: 1991-04-27
Abstract: The sliver material for spinning on a ring spinner is passed to the spinning machine in a fineness count of 0.3-0.8, having been drawn to this gauge by a drawing unit. The sliver material passes through two drawing stretches, in succession, where in the first stage the sliver is drawn to a count of 0.3-0.8, or it is reduced in two stages to the count of 0.3-0.8. In the first stage, the slivers can be doubled in the same ratio, and then drawn to a count of 0.3-0.8 in the following stage. At least two drawing stretches draw the slivers to a count of 0.3-0.8, using triple-cylinder drawing units with a max. drafting of about 200 times. The drawing stretches are used to regulate the material flow and character, or only the first stage has the regulating action. ADVANTAGE - The method reduces the whole spinning process, when working with ring spinners, and the speed of the entry rollers into the drawing stage can be virtually doubled when working with a count of 0.5

Patent DE-4117244-A1 (DE)
Inventor: HALLAS ERNST DR RER NAT
IPC: G01N33/18
Filed: 1991-05-27
Abstract: The application relates to a method and an arrangement for detecting impurities on water surfaces by means of a light absorption measurement. Regular or continuous tests for impurities have to be carried out, in particular, on rivers in the vicinity of industrial plants or power stations which discharge effluent into the rivers. The detection of oil, in particular, plays an important role in this connection. The method and the arrangement evaluate the water vapour formation on a water surface. Impurities on the water surface alter the formation of vapour at said surface. For example, an oil layer acts as a moisture barrier, i.e. water vapour is not formed, or only formed in small amounts, at points on the water surface on which an oil layer is floating. The formation of water vapour at the surface results in absorption losses in a light beam, in particular an infra-red light beam, whose radiation axis is roughly parallel to the water surface. An oil layer floating on the water surface can be detected by measuring the absorption losses. <IMAGE>
