Title: Bottom stapling machine for connecting the bottom flaps of folding boxes
Inventor: LANGE DIETER
IPC: B31B50/68
Filed: 1981-04-04
Abstract: In bottom stapling machines for connecting the bottom flaps (2, 3) of folding boxes (1), in particular made of corrugated cardboard, by means of staples (11), there are those in which the stapling head (10) is mounted with a single bearing on a bow (8) so that the staples (11) are provided at right angles to the bow (8). Since the bow (8) is mounted on a stand (7) of the bottom stapling machine, a machine of this type only has a limited working depth and thus only allows the closure of folding boxes of limited length in the region of the bottom flaps (2, 3). In order to remove this limitation and to avoid the known rotation of relatively long folding boxes, an adjustable and fixable straightedge (14) is proposed as the guiding stop for the erected folding box relative to the insertion point of the staples (11), the straightedge being arranged obliquely relative to the direction of the staples (11) and thus also obliquely to the bow (8). It is thus possible to push the folding box (1) evenly diagonally and obliquely past the bottom stapling machine, thus removing the limited processability of relatively long folding boxes (1). Additionally, in this case, each staple (11) receives an accurate firm seat in the bottom flaps. <IMAGE>

Title: Stabilisation device for dentures
Inventor: GERLACH HANS-GUSTAV PROF DR DR
IPC: A61C13/24
Filed: 1981-05-12
Abstract: The invention creates a stabilisation device for dentures which supports, in particular, the upper and lower dentures as a complete denture against one another during chewing, and balances them out in such a way that raising of the unloaded side of the dentures, especially of the lower denture, is buffered. For this purpose, a stabilising body is arranged at the maximum of the individual occlusion curve of the denture wearer at each of the two distal (rear) ends of the lower denture, which body has an essentially spherical surface directed toward the upper jaw, and recesses (concave sections) corresponding to the spherical surfaces of the stabilising bodies are provided on the two distal ends of the upper denture opposite the stabilising bodies. These stabilising bodies are of spherical design and have on their lower side additional reinforcements which are of rod-shaped, leaf-shaped, spherical or lug-like design. In addition, these stabilising bodies may also be of hemispherical design and have reinforcements on their sheet-like lower sides. Finally, baseplates on which in turn the reinforcements are arranged may also be provided on the lower side of the hemispherical stabilising bodies. The stabilising bodies and the recesses (concave sections) located opposite them may be made of a metal, plastic, porcelain or ceramic.

Title: Machine cutting constant width thin wood slices
Inventor: BEER DOUGLAS CLIFTON
IPC: B27L11/02
Filed: 1981-06-15
Abstract: Long thin slices, of predetermined width, are produced by cutting up pieces of wood along the grain lines. A rotatable carrier element (11) has a series of elongated narrow slits (55), opening out into its working surface (16). Plane blades protrude from these, to cut away slices from pieces of wood (90) laid against this surface, with the sides and grain line of the pieces virtually parallel to it and to the slits, as these pass. Each blade is part of a slice-forming assembly in individual slits. Each such assembly comprises a counter guide, arranged relative to the blade so that cut slices are thrust against the counter guide, and break lengthways in predetermined widths.

Patent DE-3139483-A1 (DE)
Inventor: GAST UWE DIPL PHYS DR
IPC: H04N1/40
Filed: 1981-10-03
Abstract: A method and an apparatus are provided for contrast intensification in the reproduction of masters in the field of electronic image processing by engraving devices and scanners. In the image-point-wise, opto-electronic master scanning, two outer field signals are obtained in addition to the image signal by scanning a first outer field and a larger, second outer field. A first differential signal and a second differential signal are generated from the image signal and the outer field signals and a third differential signal is generated from the two outer field signals. The first differential signal is combined with at least one of the other two differential signals to form an auxiliary signal which is added to the first differential signal in order to obtain a correction signal. The correction signal is then superimposed on the image signal for the purpose of contrast intensification. By employing a second outer field signal, it is particularly the disturbing edges around hard master contours which are avoided.

Title: Spinning rotor for an open-end spinning machine and process for producing it
Inventor: RAASCH HANS
IPC: D01H4/10
Filed: 1981-11-07
Abstract: At least the inner part of the spinning rotor (1) has a surface layer (4) which consists individually or in combination of iron carbide, iron boride, iron silicide or iron nitride. The spinning rotor (1) is tempered and thereby acquires an increased toughness, at the same time with a high yield point of the material. The surface layer (4) possesses a surface layer containing a foreign metal. The production of the spinning rotor takes place in steps. First, the spinning rotor is prefabricated from temperable steel. It then receives the surface layer and is subsequently either first tempered and then provided with the protective surface layer or vice versa. The protective surface layer can acquire a special outer skin. Finally, any material embrittlement caused by oxygen can be eliminated again by heating. The object is to prepare the surface of a spinning rotor and make it corrosion-resistant in such a way that good spinning results are obtained even after a long period of operation. <IMAGE>

Title: Central on-board network supply system on aircraft
Inventor: EISINGER HELMUT DIPL ING
IPC: H02J3/26
Filed: 1982-11-16
Abstract: An external on-board network supply system supplies the loads of the aircraft when it is on the ground for the purpose of servicing, having a three-phase line voltage of 208 Volt and a phase voltage of 117 Volt at 400 Hz. In order to compensate for the voltage drops which occur and to maintain the individual phase voltages continuously at the nominal value even in the case of asymmetric load, each phase voltage has an auxiliary voltage allocated to it in such a manner that the voltage vectors add to or subtract from the required nominal value. These auxiliary voltages are supplied via rotating transformers which are operated by actuating motors and are connected to the respective phase voltage. The rotating transformers are set as a function of error signals, in the sense of reducing the errors to zero.
