Filed: 1981-07-21
Abstract: A motor-driven overhead trolley conveyor is described which comprises a rail having horizontal sections and inclined sections. Rack sections or chain sections are associated to the inclined sections. Each trolley comprises its own drive motor. In the horizontal sections the driving force is transmitted exclusively through a drive roller. In inclined sections the drive is effected by means of a gear meshing with the rack or chain and being driven with the same angular velocity as the drive roller. The drive roller comprises a drive wheel connected with the drive shaft as well as a ring mounted on the periphery of the drive wheel in a slide bearing fashion. By this feature, a cold working of the drive roller surface and the rail surface due to alternate stresses caused by the gear is avoided.

Title: Method of producing an ultrasonic delay line
Inventor: SACHS BERTRAM
IPC: H03H3/007
Filed: 1981-08-12
Abstract: The ultrasonic delay line (2) contains a shaped body (6) which is connected to ultrasonic shear-mode vibrators (20, 30). According to the invention, the surface regions of the ultrasonic shear-mode vibrators (20, 30) that are to be connected to one another and the shaped body (6) are metallised using thin-film technology and then one of the surface regions to be connected is provided using thin-film technology with a solder bearing surface (24, 34) consisting of layers of a plurality of metal components in the eutectic ratio, the provision being such that in each case the individual metal components (25, 26; 35, 36) are applied consecutively in layers at a temperature below the eutectic temperature. Subsequently, said solder bearing surfaces (24, 34) are soldered above the eutectic temperature to the corresponding metallisation (10, 14). The eutectic composition of the first soldering joint is thus not produced until during the soldering process by fusing of the metal components (25, 26; 35, 36). With this method, high accuracy and reproducibility of contacting is obtained, and subsequent adjusting work is substantially reduced or becomes superfluous. <IMAGE>

Title: Overpressure valve for a packaging container
Inventor: BRAUN HARALD
IPC: B65D77/22
Filed: 1982-08-05
Abstract: An overpressure valve for a packaging container, in particular for a packaging bag made of flexible material, has a valve plate made of a first layer (4a) and of a second layer (4b). The first, relatively thick layer (4a) consists of an elastically compressible open-pore material and permanently covers an outflow opening (3). The second, relatively thin layer (4b) covers an opening (5) in the wall (W) of the packaging container only in the closed state of the valve (Figure 4 shows the opened state). This closed state is maintained by the elastic force of the first layer (4a). When the valve is open, gas passes into the atmosphere via the first layer (4a) corresponding to the arrows (9, 11, 12, 13). The valve is inexpensive to manufacture and has the advantage that it also acts as a filter which prevents the direct entry of atmospheric air into the packaging space. <IMAGE>

Title: Method for controlling a self-commutated three-phase invertor
Inventor: DEPENBROCK MANFRED PROF DR ING
IPC: H02M7/527
Filed: 1982-09-02
Abstract: This method is suitable for controlling a self-commutated three-phase invertor which forms a three-phase voltage of variable frequency and voltage from a constant input DC voltage, in order to supply a three-phase motor. The conversion takes place using the subharmonic method by pulse-width-modulated, alternating through-connection of the "plus" and "minus" of the DC voltage. In order to prevent a jump in the amplitude of the fundamental of the invertor output voltage during a changeover from triple clocking to single clocking, the intermediate pulses during triple clocking are displaced at most to the zero-crossovers of the voltage fundamental. The changeover from the triple clocking takes place either directly to an asymmetric single clocking or to a mixed triple/single clocking and subsequently to an asymmetric single clocking. In the case of the asymmetric single clocking, the switching edges are displaced by an angle which can be predetermined with respect to the zero-crossovers of the voltage fundamental. In the case of mixed triple/single clocking, intermediate pulses are provided only on each second zero-crossover of the voltage fundamental.

Title: Light measurement circuit with automatic offset voltage compensation
Inventor: KUEHNEL CLAUS
IPC: H03F3/45
Filed: 1982-10-04
Abstract: The invention relates to a light measurement circuit with automatic offset voltage compensation. The object of the invention is to improve the exposure accuracy of a photographic camera by designing a light measurement circuit which ensures that the exposure measurement voltage to be processed by a downstream exposure control circuit is free of any offset voltage component irrespective of the long-term, temperature and operating voltage response of an operational amplifier which forms a logarithm. According to the invention, in the case of circuits of this type, in which the offset voltage is transmitted into a memory, the memory can be connected via a decoupling amplifier, formed as an inverting amplifier (9) of the gain (1), by means of a changeover switch (10), which can be operated cyclically, to the non-inverting input of the operational amplifier. <IMAGE>
