Title: Weft yarn clamp - by slide action operating clamping pad on guide hook from supply bobbin mounting
Inventor: LANGR JAROSLAV
IPC: D03D47/00
Filed: 1973-06-05
Abstract: Designed for a rolling shed loom, where the bobbins of the weft carriers are charged with a measured length of weft yarn, the clamping system is operated by a slide which moves between two extreme positions to clamp or release the wefy yarn as it passes over a guide hook, so that it can be released in the charging phase, and clamped while the carrier passes through the shed to act as an anchor. The purpose is to allow positive carrier charging without stoppages, and without imposing breaking tension on the weft.
Patent DE-2330572-A1 (DE)
Title: Surgical drape - with cuff folded for aseptic opening
Inventor: COLLINS ROBERT FRANCIS
IPC: A61B46/00
Filed: 1973-06-15
Abstract: A surgical drape in the general shape of a rectangular bag is closed at the sides, but the bottom toe wall is open on the remaining wall which is surrounded by a turned back cuff into which the operator may place his hands. Prior to use the drape is folded by making a diagonal fold across the drape and then folding a portion of the toe under the cuff. When thus folded the drape may be opened by the operator without the need to shake the drape because the toe is accessible under the cuff. This reduces the liability to contamination. The drape may be applied to the leg of a patient.

Patent DE-2406181-A1 (DE)
Title: Photocomposing machine with projecting lens - has type carrier in object plane and selectively projectable type on film
Inventor: KUEHNLE SIEGFRIED
IPC: B41B17/06
Filed: 1974-02-08
Abstract: The auxiliary unit carrying the film is located at a distance from the location of the type carrier in the photocomposing machine. An auxiliary projection system produces an intermediary image of the type on the film at the location of the type carrier in the object plane, which is in turn further projected onto the setting plane with the aid of the projecting lens. The auxiliary projection system is so designed that it reduces the film type in the object plane to a size which corresponds to that of the type normally found on the type carrier. The reduction factor is adjustable and the system incorporates a field lens.

A deflection mirror is provided in the beam path between the receiving and transmitting lenses. The mirror can be swivelled with respect to both lenses. The height of the projected image can thereby be altered without the customary picture distortion. Preferably the mirror and transmitting lens are together pivotable. The mirror is advantageously connected to the frame of the receiving lens and the pivotable frame of the transmitting lens by means of rotatable cover plates or flaps.
Patent DE-2433786-A1 (DE)
Title: Textile thread length measuring system - with common pulse generator for counters on each measuring roller
Inventor: ANDERS KLAUS DIPL ING
IPC: B65H61/00
Filed: 1974-07-13
Abstract: Predetermined lengths of thread for coils and reels on winding stations for spinning machines are measured by passing the threads over driven measuring rollers. A pulse generator is coupled by a matching gear to the common shaft for all measuring rollers and acts through an electro-mechanical or electronic divider on a pulse counter, allocated to each measuring point. Separate termination signals are produced for the length measurement by the overspill of each counter. This system is much simpler and less costly because a common pulse generator suffices for all counters.
Patent DE-2436094-A1 (DE)
Title: Adjustment for wing mirror - with graduated indicator to enable driver to see amount of adjustment
Inventor: TALBOT YORCK
IPC: B60R1/06

Title: Communication unit or meter - has transparent cover plate for scale inserted into housing and fastened
Inventor: HAERTEL ERNST
IPC: G12B9/04
Filed: 1974-08-22
Abstract: The cover plate (3) has a step along its edge, with one surface resting on the housing wall outer surface (7), and the other, at least partly, on the window (2) edge (8). The cover plate (3) has, on one of its long sides (9), a flange (10), gripping behind the window edge. A bracket (14) pointing inwards, is provided on the cover plate's (3) other edge. It has projections (15) locking in recesses (16) in the housing wall. The bracket (14) does not reduce the visible surface of the scale to any noticeable extent and thus the whole area of the cut-away window can be used. The total display arrangement is not recessed within the apparatus, e.G. radiogram, and is especially useful for small apertures to give a uniform appearance to the finished article.
