Patent DE-2433339-A1 (DE)
Title: Endless strip handling machine - has stacking table height adjusted to match resistance offered to strikers
Inventor: HOERZ WERNER
IPC: B65H45/101
Filed: 1974-07-11
Abstract: The machine handles strips of material folded in the Leporello pattern, being particularly for assembling endless forms into sets. At the discharge is a stacking table indexing downwards to suit the stack height, so that the stack top remains at virtually constant level. Strikers place the strip, perforated in the transverse direction, on the stack, and if necessary form the folds also. The height of the table (6) is adjusted to match the resistance offered by the stack to the strikers (17). The latter can be in the form of eccentric discs, the torque transmitted to them regulating table height. The indexing table drive can be powered by a motor (12) switched on and off by the strikers.

Title: Automatic target card changer - new card falls from upper magazine into position with old card swung down on arm
Inventor: MURSO BERNHARDT
IPC: F41J7/00
Filed: 1974-07-13
Abstract: The automatic target card changer for small arms firing practice, has a magazine (2) for the cards (16) at the top of the housing (1) which tilts about a pivot (18) so that the front of the top card is in contact with a feed roller (3) so that when the drive is switched on, the card is fed by a guide (6) to pass between rollers (7, 8) and fall vertically in position in the aperture (1a) of the housing, resting on a support (20). Behind this support is a photo cell or microswitch (11) to stop the drive. When the next card is required, the support which is mounted on a swinging arm, is lowered and the used card travels down a guide (12) below to fall into a tray (13) at the box. The cycle is then repeated.

Title: Video signals circular gating - parabolic voltages are derived from horizontal and vertical frequencies delivered by timing generator
Inventor: HOEREN VOLKER
IPC: H04N3/22
Filed: 1974-08-01
Abstract: Parabolic voltages are superposed and the sum voltage amplitude is clipped. Parabolic voltages are digitally generated by counting pulses delivered by the timing generator, and a gating signal is obtained from comparison of a selected level defined as a counting result, with the above digitalised sum voltage. A store is allocated to each presettable horizontal and vertical pulse counters, and connected to the adding stages, whose outputs are connected to digital comparators. Their other inputs receive pulses obtained by presetting the horizontal and vertical counters, so that the required gating signal appears at the comparator output. The gating signal is generated by a clock pulse controlled D-flip-flop.

Title: Sound attenuated forming press unit - servo motor moves tension rod carriage w.r.t. cam housing
Inventor: VINSON PAUL
IPC: B30B1/26
Filed: 1974-08-30
Abstract: Forming press for sheet metal or ceramic material is constructed as a sound attenuated unit in which the tools belonging to the press carriage may be encapsulated, and the total noise generated in the press is reduced by driving the press carriage, by cams which are in contact with cam followers during the entire work cycle of the press carriage, i.e. to give a power stroke and a return stroke during one cam shaft revolution. The press carriage (99) is mounted on the top of vertical tension rods (101) which in turn are mounted in a support construction (111) for axial reciprocating movement. A tension rod carriage (85) connected to tension rods (101) is driven by one or more cam followers (55, 57) which drive the tension rods. A servo motor worm drive moves a bolt and nut arrangement to alter the position of the tension rod carriage w.r.t. the cam housing.

Title: Polishing cylinder for flat wooden surfaces - is made from cylinder round which strip of abrasive material is wound
Inventor: BECKER WOLFGANG DIPL ING
IPC: B24D9/04
Filed: 1975-05-07
Abstract: The strip of abrasive material which is wound on the roller is narrow compared to the width of the cylinder. It is wound spiral wise round the cylinder with its edges touching and forming a seam. The cylinder is first covered with a layer of rubber or similar material vulcanised onto the cylinder. The abrasive strip is mounted over the rubber covering by an adhesive, or by a double sided adhesive strip which is also wound in a spiral round the cylinder, but with its joining seam offset from that of the adhesive strip. The polishing cylinder can be quickly and easily made and because of the rubber layer, polishes without chatter marks.

Title: Signalling system between main and PBX telephone exchanges - uses same generator for audible sounds and secondary signalling (BE240177)
Inventor: JAEGER HORST
IPC: H04Q1/44
Filed: 1975-07-23
Abstract: The signalling system, for signalling between a main telephone exchange and a PBX has the secondary signalling signals that follow the main signalling signals produced in a simple manner. 50 Hz AC is used for main signalling and AF multiple-freq. signals are used to perform the secondary signalling functions. The AF signals used for making audible sound are also used for secondary signalling signals -- i.e. both audible and secondary signalling signals are derived from the same AF generator. This reduces the number of components. The number of available secondary signals can be increased by combining several one after another.

Title: Yarn delivery store mechanism - has reciprocating push bar with profiled end to move yarn coils along store drum
Inventor: LAURSEN OVE
IPC: D04B15/48
Filed: 1975-09-12
Abstract: An appts. is claimed to store yarn in coiled windings as it is being passed through a yarn delivery mechanism, with an oscillating yarn guide to manipulate tangential windings round a drum, and pass them along the drum. The advance bar oscillates in a reciprocating motion radially to the drum axis, with a push surface ranging outwards from the drum wall in the direction of the advance of the yarn windings. The design gives a simple method of passing the stored yarn in coils along the store drum, reducing the height of the unit as there is not angular positioning of the advance component.
