Patent DE-3212813-A1 (DE)
Title: Laminate for preferred use in the construction of model aircraft and ships
Inventor: LOERKE JOACHIM
IPC: B32B7/022
Filed: 1982-04-06
Abstract: To improve the surface hardness and quality, as well as the mechanical strength of the outer skin of a model aircraft (ship), an asymmetrical laminate, comprising a hard thin outer layer and a lightweight thicker inner layer which are adhesively bonded before assembly, is used as planking. Elastic monoaxial deformability is preserved here for assembly. Given the high surface quality of the laminate, on the outside no finishing or surface protection is required, on the inside the laminate remains suitable for adhesion and working. Apart from the combination of fibre-reinforced plastic on the outside / balsa wood on the inside, further material pairings are described in the subclaims.

Patent DE-3239660-A1 (DE)
Title: Compressed-air wheel
Inventor: NAUJOK EDWARD
IPC: B60K3/04
Filed: 1982-10-27
Abstract: The vehicle operated by means of a manually created gas pressure via a hydraulic turbine affords, through the concept of the conversion of human muscle power into gas pressure, and so into a pressure force, the possibility of storing the same in a pressure container, from which it is available again in the event of need. The utilisation of the gas pressure and conversion of the same into a rotary movement which can be used as a driving force is carried out by the hydraulic turbine. In this connection, the force expended is at the same time increased by the hydraulic action of the turbine. The rotary movement delivered from the hydraulic turbine is transmitted to the driving axle of the vehicle and can thus be used for operating the vehicle. In order to store the overcapacity freed in the event of a lower driving force requirement arising as a result of outside conditions during driving operation, the compressed-air wheel is equipped with a shaft-locking freewheel and a freewheel system from the drive shaft of the vehicle to the pressure box or compressor. This freewheel system transmits the rotation of the vehicle axis to the drive shaft of the pressure box and keeps the latter in operation. The shaft-locking freewheel is set in operation as the driving axle of the hydraulic turbine in the event of faster rotation of the vehicle driving axle. The overrun, arising as a result of the faster rotation of the vehicle axle, of the toothed ring of the shaft-locking freewheel blocks, by means of its mechanism, the ...

Title: Self-blocking belt-reeling mechanism for safety belts, especially in motor vehicles
Inventor: BUTENOP KLAUS
IPC: B60R22/38
Filed: 1983-05-06
Abstract: In a self-blocking belt-reeling mechanism for strap-in safety belts, especially motor-vehicle safety belts, having a shaft which is mounted in a housing and is under spring tension and onto which the belt can be reeled, and a slow-acting blocking member which is mounted eccentrically on one shaft end and, in response to a predetermined rotational acceleration of the shaft in the unreeling direction of the belt, experiences a movement directed outwards and which butts against stops fixed to the housing and in the form of a toothed ring, the blocking member having a curved recess with at least one further stop, into which engages an extension which is located on the shaft end and which, in the event of a relative movement between the shaft and blocking member, serves as the stop for the blocking member, there are problems involved in providing an advantageous load pattern on the shaft and in reducing the relatively large angle which has to be covered until the blocking member engages into the toothed ring, in order even further to shorten the time for the blocking facility to be activated. To achieve the object arising from this, it is proposed that the eccentric point (28) for the eccentric mounting (26, 27) of the blocking member (13) be arranged at least on the circumferential line (20) of the shaft (10), preferably outside this, and that the extension (11) located on the shaft end as well as the blocking member (13) mounted on said extension, together with its curved recess (21, 22), have guide faces (19, 26, 38) which form segments of circular lines described about the eccentric point (28), so that the blocking member (13) is guided only on the circular paths thus formed. Where a plastic shaft with a steel core (32) is concerned, the latter can have, in the bearing region of the blocking member (13), a perforation (34), into which engages at least one cam (35) of the blocking member, so that the latter is secured against movements in the direction of the shaft axis (17). <IMAGE>

Title: Brushless DC fan motor
Inventor: DEAVERS CLYDE J
IPC: H02K7/14
Filed: 1983-09-09
Abstract: A simple brushless DC motor uses an annular permanent magnet (14) which is magnetised in segments arranged in the circumferential direction. The successive segments in the circumferential direction are magnetised radially and in opposite directions. Fan vanes (17) are located inside the annular magnet (14). A coil (41) and a magnet construction having two pole pieces (48, 49) are arranged outside the permanent-magnet annulus (41). A Hall-effect device (X1) switches the coil (41) off and on as a result of the passage of the segments of the rotor magnet (14). The single coil (41) which is commutated in this manner produces a rotation of the rotor (11) and fan vanes (17). A permanent magnet (50), which is mounted on the stator, ensures a specific magnetic alignment of the rotor (11) when it is at rest, as a result of which the starting of the motor is ensured.

Title: Arrangement for cooling the wire in drawing machines
Inventor: PFEIFFER HANS DIPL ING
IPC: B21C9/00
Filed: 1983-09-14
Abstract: In the drawing of wire, the wire is heated in a manner corresponding to the deformation performed and is then often insufficiently cooled, thus being fed at an undesirably high temperature to downstream reels and subjecting their coils to impermissably high stresses due to shrinkage effects which occur during cooling. According to the invention, a separate cooling cylinder 2 receiving a multiplicity of turns of the wire 16, which form non-overlapping coils, is arranged downstream of one or more, and at the very least of the last, die of a drawing device and this cooling cylinder is expediently equipped with feed screws 8 which are arranged in a uniformly distributed manner, are operated in synchronism with the cooling cylinder, project beyond the circumferential surface of the latter and push the coiling wire forwards axially, with the result that the wire upstream of the reels enters into large-area contact with the surface of the cooling cylinder cooling it and is transported onwards in a continuous manner in order to guarantee space for more wire as it arrives.
Patent DE-3334817-A1 (DE)
Title: Arrangement of a number of electrical low-pass filters
Inventor: ROEHRLE JOSEF DIPL ING
IPC: H03H7/06
Filed: 1983-09-26
Abstract: A number of electrical low-pass filters are in each case constructed in such a manner that their input (E0 to E3) and output (A0 to A3) respectively is in each case at reference potential with a first terminal. The second terminal both of the input and of the output are connected to one another via a first resistor (R7, R9, R11). The second terminal of the output is also connected to a first contact of a capacitor (C4, C5, C6), the other contact of which leads to a second resistor (R8, R10, R12), which is connected to the reference potential. All second resistors of the low-pass arrangement are integrated to form one resistance network (W1). The circuit allows in each case one resistor terminal of these resistors to be integrated to be connected to a collective contact (SK), as a result of which a relatively high integration density can be achieved. <IMAGE>
