Patent DE-2732641-A1 (DE)
Inventor: HEIMLICHER PAUL
IPC: B41F13/62
Filed: 1977-07-19
Abstract: Each folding cylinder (7, 10) has on its circumference two groups of different numbers of fastening devices (6, 17, 21). These numbers are not in an integral ratio to one another. For example the first group comprises three, the second four fastening devices. The latter serve to receive operating mechanisms such as folding knives (11), folding flaps (13), grippers (8) and the like. The operating mechanisms are accommodated in cassettes. If, therefore, in the case of six engravings, for example four, operating mechanisms are used, instead of three, their spacing on the folding cylinder circumference is smaller, leading to lower accelerations. The machine speed therefore only needs to be reduced to an insignificant extent with consideration of the folding apparatus with six engravings compared to that with four. <IMAGE>

Title: Continuous hot gluing press for leather and footwear blanks etc. - has low-pressure zones to smooth out the blanks before bonding them in high pressure zones
Inventor: DOKOUPIL JIRI DIPL ING
IPC: B65H29/24
Filed: 1977-12-27
Abstract: The process is of the type in which, partic. a pair of superimposed blanks are hot-glued together as they are conveyed through a pressure zone. The path followed by the conveyor carries blanks successively through a low pressure zone, which spreads and smooths out the blanks, and then through a high pressure zone to undergo the pressing operation. The conveyor path rises progressively from the blank loading station. Processed blanks are discharged at a point above the feed station and travelling in the opposite direction to blanks being loaded below. The converyor path is pref. provided by lapping a conveyor band around a major arc of a rotary drum and carrying blanks sandwich fashion between band and drum. The low pressure zone is provided by band pressure on the drum due to band tension alone. The high pressure zone is pref. achieved by using a loaded roller on the side of the band remote from the drum. Used for hot bonding together blanks in laminated pairs for the leather, footwear and clothing industries. The machine has a very high output and is simple to use, a single operator being able to watch and reach both feed and discharge stations. The prod. is free from wrinkles, being smoothed at low pressure before the main pressing operation.

Title: Four-wire TDM telephone exchange - has additional switching matrix with several switching groups each having access to other groups via four-wire link
Inventor: DIETZE KLAUS DIPL ING
IPC: H04Q11/04
Filed: 1978-01-11
Abstract: The 4-wire TDM telephone exchange needs fewer switching matrices and fewer crosspoint switches. Connection lines are formed into groups each with a bus for both directions. The buses of a group are connected via an internal group switch. For connections between different groups the bus-bars of the individual groups form the input and output lines of a further switching matrix. This matrix has several switching groups each with a given number of connection groups. Each switching group also has access via TDM, 4-wire link lines to the other groups in this extra matrix or can be reached from these other groups.
Patent DE-2802536-A1 (DE)
Title: Control circuit running open=end spinning machine - compensates for slip between larger yarn package and driving cylinder
Inventor: TAKEUCHI TATUO
IPC: D01H4/44
Filed: 1978-01-20
Abstract: In an open-end spinning machine with a number of units, each unit comprises a turbine with a feed roller for a strand of fibres; with a winding cylinder for drawing the yarn from the turbine and winding it on to a tube; with a winding tube holder in which the tube is free to rotate; with separate drives for feed roller and winding cylinder and with couplings for transmitting the drives. Detectors are provided to gauge the amt. of yarn wound on to the tube, and there are control devices with the help of which, a timed control of the feed roller and winding cylinder can be effected, dependent upon the amount of yarn wound on, by a timed engaging and disengaging of the couplings. The detectors work so as to gauge the amount of yarn wound on as a function of the degree to which the yarn tube holder has pivoted. A shaft turns together with the detector and the winding tube holder, and the angle through which the shaft turns is detected, for pref. by means of a number of limit switches, contacted by a tappet fixed on the shaft. Alternatively a potentiometer may be coupled to the shaft. Or photo-electric cells may be positioned on the arms of the fork holding the winding tube. Arrangement overcomes the difficulties with existing systems that when a large amt. of yarn is wound on to the tube, the inertia of the package causes slip. This has the result of distorting timing intervals. The feed back of the yarn when an end is broken does not coincide with the delivery of fibres from the opener to the turbine. When the drive is reversed slip causes winding on to commence a fraction of time later. On stopping, the slip imposes excessive tension on the yarn at the nip of the draw rollers and this may cause a breakage.
