Title: Method and apparatus for forming a stack of bags
Inventor: BAADER JOSEF DIPL ING
IPC: B31F1/10
Filed: 1988-04-02
Abstract: The invention relates to a method for forming a stack of bags, in particular of bags for photographic work after a treatment station to which they are fed one after the other, through which they are guided and set down in the same sequence in the stack. Prior to being set down on the stack, the bags are provided with recesses, grooves, beads or rims which are continuous in the transport direction and are of such a thickness that, independently of the initial state, the bags are approximately straightened in the longitudinal direction at least for the time until the next bag is set down on the stack. <IMAGE>

Title: Drilling device for making undercut drill holes
Inventor: FISCHER ARTUR PROF DR
IPC: B23B49/00
Filed: 1988-09-02
Abstract: Drilling devices for making undercut drill holes use drills whose drill head has laterally projecting side cutting edges. When the drill reaches the required drill-hole depth, an undercut is produced at the bottom of the drill hole by swinging out the drill. In order to obtain effective linear guidance for drills of this type during the drilling operation, a centring sleeve is provided which tightly encloses the drill shank in its rectilinear part, the drill shank having in its top area a conical taper which defines the swivel angle of the drill when the required drill-hole depth is reached.

IPC: G06K7/10
Filed: 1989-02-07
Abstract: In order to enable the evaluation even of bar codes which, because of damage, contamination or the like, have no complete bar code lines within a finite angle, especially within a right angle to the direction of extension of the individual bar code bars, it is proposed, according to the invention, that the bar code is picked up by a camera, that it is sampled columnwise, that the intensities of each scanned column are determined and only intensity values above prescribed thresholds are taken into account, or that the average value of the intensities of each scanned column is detected.

Title: Method and device for the detection of knocking signals
Inventor: DORNER ROBERT DR ING
IPC: G01L23/22
Filed: 1989-04-08
Abstract: For the detection of knocking signals in internal combustion engines it is usual to filter out only the signal contents of the fundamental wave. In the present invention the entire knocking noise signal is subjected to comb filtering in order to detect the signal contents of the fundamental and harmonic waves and to perform a corresponding analysis of these. Such a measure is essentially more significant and reliable with regard to suitable measures for the suppression of knocking noise.

Inventor: LISEC PETER
IPC: E06B3/673
Filed: 1989-04-28
Abstract: When filling hollow molds, to be bent into spacer frames, with a hygroscopic material, the filling process is interrupted as soon as the material filled into the hollow molding has reached a location of the hollow molding where the latter is to be bent into a corner. At this location, the wall of the hollow molding which subsequently forms the inside in the spacer frame is made to bulge. Then introduction of hygroscopic material into the hollow molding is continued, interrupted at the next location of a corner, the walls are made to bulge, until four locations of the sidewall in the hollow molding have been provided with a bulge, and the hollow molding is completely filled. Also, a device is described suitable for performing the process. This device comprises a stamp (16) for indenting the hollow molding and an ultrasonic sensor which responds to the filling level of the hygroscopic material in the hollow molding.

Title: Lea exchange - measures spun yarn length to determine automatic lea change action
Inventor: SIMON KARSTEN DIPL ING
IPC: B65H63/08
Filed: 1989-09-05
Abstract: To exchange leas at a spinner, the length of the spun yarn is indirectly measured, to give the amt. of fibre material remaining to be spun, for a new lea to be delivered automatically before the current lea is exhausted. Pref. the amt. of fibre material is measured of the spun yarn, or the count of wound bobbins produced from the lea achieved by counting the bobbin doffing actions. The amt. of spun yarn is measured in fixed time units. The measurements of the spun yarn and the speed of fibre consumption give the lea delivery time until empty, and the amt. of fibre material remaining while the lea is prepd. for exchange. The bobbin count is taken at the following winder. In the case of an open-end spinner, the sliver can count is taken with the number of bobbins produced from a can, and with a pneumatic spinner the number of bobbins is taken per roving bobbin. ADVANTAGE - The method gives an accurate indication with the lea is to be exchanged, without significant mechanical modification.
