Patent DE-3711766-A1 (DE)
Title: Packaging for round containers
Inventor: MORSBACH GUENTER
IPC: B65D71/38
Filed: 1987-04-10
Abstract: Packagings, consisting of a packaging material blank made of cardboard or the like, for round containers, in particular cans, bottles and the like, for example beverage containers, are already known, for example a plurality of box-like packaging bodies being formed, which are fixed to one another by their transverse cardboard sides in order thus to form a transverse combination of two packaging bodies. Packagings of this type, however, are generally not sufficiently sturdy, which often leads to damage to and/or loss of the containers. In contrast, in the new packaging, an exceptionally good holding between individual packaging bodies is guaranteed, that is to say, for example, between the 6-packs 4 forming a 12-pack 7 or 9 on the one hand and between the 12-packs then forming a 24-pack 7 and 9, a first hoop 8 engaging around the transverse combinations 7 or 9, for example the 12-packs, as well as a second hoop 11 engaging around the transverse combinations 7 or 9 fixed to one another being secured against slipping off in relation to the height of the round containers to be packaged. An overall combination is thus formed which is sufficiently sturdy for transportation, but is sufficiently detachable for sales. <IMAGE>

Title: Transmission system with optical waveguides
Inventor: MEINHOLD HENNER DIPL PHYS DR
IPC: H03M1/24
Filed: 1987-04-09
Abstract: This transmission system with optical waveguides is used for forming a fibre-optical absolute position detector, for example for detecting the position of switching elements of a high-voltage switching panel. A first optical waveguide (2) connected to an optical transmitter (1) is provided which is connected via a distribution point (3) to n (n = 2, 3, 4 ...) fibre links (4, 5, 6) of different lengths in each case. The said fibre links (4, 5, 6) are conducted via light barriers (7, 8, 9) and connected at an injection point (13) to a second optical waveguide (14) connected to a photo-receiver (15). The light barriers sample a coded position encoder (19). The position encoder (19) has coding holes (A, B, C ...) and can be constructed as "ruler" or as "disc", depending whether an absolute distance or an absolute angle is to be detected. The fibre links (4, 5, 6) form delay lines so that a single emitted pulse (I) is distributed over a number of pulses (II, III, IV) arriving successively in time at the photo-receiver. <IMAGE>

Title: Measuring instrument
Inventor: ROSS GUENTHER
IPC: G01B5/008
Filed: 1987-09-03
Abstract: In a measuring instrument, a coordinate measuring machine (1) is arranged on a foundation block (2). The aim is to measure a workpiece (13) which is long in the Z-direction with a high measurement accuracy without the measurement range (10) of the sleeve (5) being correspondingly large in the Z-direction.

Patent DE-3828624-A1 (DE)
Title: 121.5/243 MHz emergency receiver concept
Inventor: WEINZIERL FRANZ DIPL ING
IPC: H03D7/18
Filed: 1988-08-24
Abstract: 121.5/243 MHz emergency receivers are permanent components of aircraft radio facilities. The RF section of an emergency radio receiver concept is described which reduces the technical expenditure and thus allows the further miniaturisation of emergency radio receivers, for example in thickfilm technology. A single IF at low frequency, for example 455 kHz, is provided. To obtain adequate image rejection for this, high attenuation is required at the RF input for the image rejection. According to the invention, this is achieved by crystal filters at the input frequency preceding the mixing stage. The essential savings are based on     - absence of double frequency conversion, as a result   - no problems with spurious receiving locations, - low power consumption because of the low single IF and omission of a double IF, - size advantage of crystal filters compared with large-size RF input coils with a high Q.

Patent DE-3835030-A1 (DE)
Title: Method for commutating brushless DC motors
Inventor: KOTHE KARL-PETER DIPL ING
IPC: H02P6/15
Filed: 1988-10-14
Abstract: A brushless DC motor has a permanent-magnet rotor (1) and stator windings (R, S, T) arranged in a Y-connection as the rotating-field winding. A DC source (2) is connected via a bridge circuit (3) to the stator windings (R, S, T) in such a way that they are supplied in pulsed manner with DC, so that a rotating field is sustained in the stator within which the rotor (1) rotates. In the case of commutation in motor operation, the stator windings are switched so that at the end of the commutation process, the switching off of the transistor (T1) carrying current to the first, previously current-carrying, stator winding (R) is delayed until the current-carrying transistor (T5) of the second, subsequent stator winding (T) is already switched on. This increases the current-flow angle and therefore the torque. <IMAGE>
