Title: Measuring device for making a joint between surfaces arranged apart and skewed relative to one another
Inventor: KLOETGEN STEFAN
IPC: G01B3/08
Filed: 1994-04-02
Abstract: Making a workpiece for joining or matching abovementioned surfaces represents a not inconsiderable outlay of work, both in determining and in transmitting the dimensions. Furthermore, the summation of the work steps produces a source of error. This outlay is substantially simplified by means of the measuring device in conjunction with simultaneous elimination of errors or inaccuracies, and there is no need to read off data relating either to length or angle. The device consists of two elements situated one above another, which can be displaced lengthwise. One plate is mounted respectively at the two ends in the form of a right angle triangle and can be adjusted to arbitrary angles. The device includes a scale of data for length and angle, and a spirit level. It can be matched arbitrarily to the objects to be joined, and can be locked and transferred in this way onto the workpiece. The measuring device is applied in all areas of handicraft in which measurements described above are required, in particular woodworking, the construction sector and do-it-yourself. <IMAGE>

Title: Automated yarn end capture from reel in open-end spinning
Inventor: MAYER WALTER
IPC: D01H4/50
Filed: 1994-05-28
Abstract: A process for capturing the end of yarn wound on a spool entails bringing a suction air current onto the spool circumference, winding the spool in reverse tensioning the yarn end exposed by the current and drawing it from the spool. Here, the yarn end, loosened by reverse rotation and captured by the suction is monitored for its presence in the flow thereafter. If its presence is established the spinning start-up programme is initiated and completed in the usual way. If it is missing after a predetermined time spool unwinding speed is reduced, the monitoring of the yarn end in the air stream is continued and if the yarn end is present spinning is initiated, etc. If, after a fixed period, the yarn end is still missing from the flow, the spool is brought to a stop and a signal emitted.
