Patent DE-3342626-A1 (DE)
Title: Floor plate made of reinforced or prestressed concrete for road bridges or the like
IPC: E01D19/12
Filed: 1983-11-25
Abstract: In a floor plate made of reinforced or prestressed concrete for road bridges, the longitudinal and/or transverse reinforcement of the floor panel (4) of the supporting framework consists of reinforcement elements (8, 9, 10) which are protected against corrosion. Arranged above the floor panel (4) is a compensating and wearing course (11) which is directly driven on and consists of a tensionproof and wear-resistant concrete, e.g. fibre concrete, and is connected in a shear-resistant manner to the supporting framework (4) e.g. by a reinforcement mat (12) with rod ends bent out of its plane. The use of corrosion-protected reinforcement elements provides the precondition for foregoing the usual insulation between the wearing course and the supporting framework. This provides the precondition for a material being used as the layer driven on, which is especially suitable for the requirements to be made of it, e.g. steel-fibre concrete. <IMAGE>

Title: X/Y recorder with externally drivable null adjustment, particularly for the computer-controlled logging of material fatigue tests
Inventor: BECKER PAUL ING GRAD
IPC: G06K15/22
Filed: 1984-01-26
Abstract: The present invention relates to improving the documentation of automated test sequences by modifying an X/Y recorder (3). It is not only the automation of the test sequence which is of interest but also a simultaneous, if possible, automatic documentation with little equipment expenditure, particularly in material fatigue tests in which a specimen (11) is cyclically stretched on a test stand (12). According to the invention, the null setting of one or both coordinates of an X/Y recorder is changed in steps by feeding in (26, 27) an additional voltage, and the servomotor is switched off during the pauses in recording by an external relay in order to increase the recorder service life. This makes it possible to record several curves, selected by the computer (4), adjacently to one another on one sheet used as a test log without requiring a paper advance. This automatically generated test log can be directly used for the test documentation to be generated later. <IMAGE>

Patent DE-3411838-A1 (DE)
Title: Pivoting beam antenna for space radio stations
Inventor: DONDL PETER DIPL ING
IPC: H01Q3/30
Filed: 1984-03-30
Abstract: In the case of a pivoting beam antenna for a space radio station which moves on a defined flight path relative to its illumination region, it is intended that the illumination region should have approximately the same power flow intensity irrespective of the changing distance. This is achieved in that the pivoting movement, which is directed onto the illumination region 9, is coupled to a change in the beam angle 4, 5 and/or the gain of the antenna with the aim of identical illumination, even at different distances. This coupling can take place mechanically or via a computer. Mechanical coupling is possible, for example, using a reflector 13, 15 which is articulated on one side and is constructed such that its free end can move relative to the exciter for beam pivoting and hence defocuses or focuses the excitation radiation directed onto it. The change in the beam angle and/or gain resulting from the beam pivoting can also take place using a phase-controlled multiple-exciter antenna, the pivoting angle being entered into a computer and being used as the control variable for the beam angle and/or gain. <IMAGE>

Patent DE-3437740-A1 (DE)
Title: Electrical balance
Inventor: KUNZ PETER
IPC: G01G7/04
Filed: 1984-10-15
Abstract: In an electrical balance with a load receiver (30, 32) and with a permanent-magnet system (70, 72, 74) and a live coil (54) for load compensation, arranged in the magnetic field of the latter, the permanent-magnet system comprising an essentially rectangular box (70, 72) for receiving at least one permanent magnet (74) and the coil (54), it is proposed to form the box from two U-shaped ferromagnetic sheet-metal parts (70, 72) which engage one into the other in an offset manner. This design combines great ease of assembly with the advantage of regularly being able to do without an additional magnetic shielding plate and therefore of saving constructional height, since the largely closed box (70, 72) now has only a very small magnetic stray field. The invention is used especially in precision balances with medium indicating resolution. <IMAGE>

Title: Plunger-type armature magnet system having an armature which is constructed as a push rod, especially for a printing hammer device
Inventor: MUENSTER DIETMAR ING GRAD
IPC: B41J9/06
Filed: 1984-11-19
Abstract: Known plunger-type armature magnet systems, especially for printing hammer devices, still consist of a large number of individual parts which have to be adjusted and are not well suited for cheap mass production. In addition, individual parts cannot be assembled using automata. These disadvantages are overcome according to the invention in that the magnet housing consists of a U-shaped yoke part (22) and a flux guiding element (25) which can be firmly connected to one another by means of its free limbs (23, 24), in that the circular recesses, which surround the armature (15) with small air gaps, are arranged in the flux guiding element (25) and in the connecting web (26) of the yoke part (22), and in that the coil former of the excitation coil (16) is supported in an axially secured manner, by means of bearings which are arranged on the end surfaces (28, 29) of the two flange parts, in bearing recesses in the flux guiding element (25) and in the connecting web (26), and is provided in its core with a through-hole in the longitudinal direction which has constrictions at the outlet ends for supporting the movable armature (15) without play. In consequence, easy assembly of the individual parts of the plunger-type armature magnet system is made possible in the same assembly direction, simply by plugging together, which can reliably be carried out by an automaton. The plunger-type armature magnet system additionally has a very simple and compact construction, with few individual parts. <IMAGE>
