Patent DE-3644899-A1 (DE)
Title: Aircraft
Inventor: KOUHIA NIILO NIKOLAI
IPC: B64C39/00
Filed: 1986-07-07
Abstract: The aircraft consists of a round fuselage, a ring, a control and monitoring mechanism and a payload compartment. The aircraft is intended to be used as a novel type of vehicle which enables smooth onward motion through the air by utilising air masses and air flows. The aircraft has the form of an inverted plate with flat edges and a planar base. The cockpit is located in the dome-shaped upper part. The lower part of the vehicle is formed by a ring which rotates vigorously about its axis or its centre point and has a large diameter, this also determining the external shape of the aircraft (Figs. 1 and 2). The outer casing of the apparatus produces its fast lateral onward motion, and rapid descent of the vehicle is prevented by the large lower surface. The technology of the aircraft is based on the fact that the vigorously rotating ring holds the aircraft in the horizontal position (gyro phenomenon) and prevents any abrupt motions. As a result of its rapid rotation, the ring B (Fig. 2) compensates for the weight of the vehicle, and the variation in the angular velocities of the ring produces the easy controllability of this aircraft. <IMAGE>

Title: Screw connecting terminal
Inventor: GIEGOLD PETER
IPC: H01R4/38
Filed: 1987-07-28
Abstract: A screw connecting terminal (10) which is used for the conductive connection of electrical cables for low-voltage apparatuses and installations consists of a terminal socket (11) which is preferably in the form of a box, a screw element (12) and a U-shaped pressure piece (13) which is driven by the screw element in the screwing direction, one (the upper) of whose free limbs (24), originating from a connecting limb (23), is held close to the operating end (19) of the screw element while its other (lower) free limb (25) projects into the interior of the terminal socket and can accommodate the electrical cables (which are to be connected in a conductive manner), clamping said cables to one another, between them and a base-side clamping wall (16) of the terminal socket. This screw connecting terminal is distinguished by the fact that that free limb (24) of the U-shaped pressure piece (13) which is held at the operating end of the screw element (12) is equipped with a longitudinal slot (26) which extends from the limb end to at least close to the adjacent connecting limb (23) and expands in the region of the screw axis of the screw element to form an approximate oval or circle-like opening (27). The edges of this opening engage in a circumferential groove (22) which is located in the region of the operating end of the screw element. This construction makes it possible to assemble the parts to one another simply and reliably. <IMAGE>

Title: Vehicle seat
Inventor: PFEIFFER KLAUS DIPL ING
IPC: B60R22/02
Filed: 1988-03-10
Abstract: In the case of a vehicle seat, especially a rear seat, with a sitting cushion, a back rest and a safety belt with a belt retractor and a belt lock for locking the buckle latch held on the belt, when the safety belt has been taken off, the belt lock is in a "cleared away" position inside a recess in the sitting cushion or in the back rest. When the safety belt is in use, pulling of the belt by the belt retractor automatically transfers the belt lock into an accessible insertion position, in which the buckle latch can be inserted into the belt lock. The automatic transfer of the belt lock is brought about by means of a moving spring which engages on a holder supporting the belt lock and is tensioned in the cleared-away position by locking of the holder. The locking action is automatically terminated when the belt is pulled off by the belt retractor.

Patent DE-3819214-A1 (DE)
Title: Circuit arrangement for the adjustment of the average brightness of an image displayed with a video signal
Inventor: HAIST WALTER DIPL ING
IPC: H04N5/57
Filed: 1988-06-06
Abstract: In X-ray television systems it is often required that the average brightness of significant image portions can be controlled to a desired value independently of the grey-scale value of the remaining image. In so doing, the problem arises that the amplitude of the integrated video signal is a function of the magnitude of the significant image portions. According to the invention, this problem is solved in that both the video signal and the signal of a desired value transmitter are led in each case via a switch (S1, S2), which is closed during the times in which the video signal of the significant image portions occurs. The output signals of both switches (S1, S2) are fed to integrators (I1, I2) having the same time constants whose output signals are fed to a controller (R) and to whose output the control input of an adjustable attenuation element in the video signal path is connected. The invention is installed in X-ray television systems. <IMAGE>

Title: Method for fabricating a negative storage electrode for alkaline accumulators
Inventor: WINSEL AUGUST PROF DR
IPC: H01M4/30
Filed: 1988-07-04
Abstract: In the fabrication of a plastic-bound, negative roll electrode having a copper matrix from a CdO/Cu2O powder mix, which after being pressed or rolled, into a copper mesh is treated with a reducing current in order to generate a filigree, electronically conductive Cu pattern, it is important for the quality of the finished product that, from the CdO and a small amount of binder (PTFE), a granular material is first produced which is then admixed with the Cu2O and the larger remaining amount of the PTFE provided, and that the potentials during the cathodic reduction are maintained at values at which hydrogen generation does not yet take place. Galvanic cells having the electrode combination positive sintered electrode/negative roll electrode come close, in terms of their heavy-current carrying capacity, to conventional cells of the sintered/sintered electrode version.

Filed: 1988-12-20
Abstract: A commutator motor comprises poles consisting of two or three pole pieces and a one-part or three-part field winding on a stator forming a magnetic return path and operable in either direction or in a direction which can be switched. The field magnet has three pole pieces. The central pole piece (14), whose width is 1/4 of the armature circumference, is connected on either side to another pole piece (15, 16). Together, the pole pieces (15, 16) constitute the total pole width. When the armature rotates in a predetermined direction, the field winding consists of the winding part (18) wound around the central pole piece (14) and the pole piece (15), and the brushes adopt a position such that the central axis (12) from the centre of the pole field (7) to the neutral region (8) of the armature is directed to the pole core centre of the pole field width in such a way that the armature cross-field returns principally through the pole piece (16) which it excites.
