A holding device for mounting a shear strain gauge 14 in an airplane axle 1 in which the shear strain gauge 14 consists of a coil part 18 with two magnet coils 19 spaced apart from each other and of a disk part 20. The disk part 20 has a disk 21 which, in normal position, extends equidistant between the magnet coils 19. The holding device has two holding rings 16 and 17 arranged axially at a given distance from each other, the coil part being adapted to be fastened to the one holding ring 16 thereof and the disk part 20 to the other holding ring 17. The holding rings 16 and 17 are developed with radial resilience and with a smaller outside diameter than the inside diameter of the airplane axle. They have radially protruding holding lugs 23 which rest under initial spring tension against the inner wall of the airplane axle 1. The holding rings 16 and 17 have support parts 28 and 28', the coil part 18 being adapted to be fastened to the support part 28' of the one holding ring 16 and the disk part 20 to the support part 28 of the other holding ring 17.
摘要:
By the fastening device, two electric transmitters are to be arranged on a supporting structural part from which two extensions (11) protrude spaced from each other. For this purpose, one bored attachment end (15, 16) each of the two transmitters are arranged each on one side (13, 14) of one of the two extensions (11) on a threaded bolt (1, 2). The threaded bolt is screwed, with one collar (5, 6) each lying on both sides against the extension (11), directly to the latter. The attachment ends each have such a large recess (20 22) that they rest only on the extension without resting on the collars (5, 6). The threaded bolt (1, 2) is provided on the outside on both ends with a threaded section (9, 10). Nuts (25, 26) which are screwed on the respective threaded sections press in each case one of the two attachment ends (15, 16) against the extension (11).

An arrangement is disclosed for time division multiplex data transmission with a bus system which includes a bus line and a plurality of participators or terminals connected to the bus line in data transmitting connection with each other in a predetermined succession in a predetermined combination, in which each participator or terminal has at least one programmable counter having a counting input for connection with a synchronizing signal generator and an output for connection with a switching device to produce a data transmitting connection between the bus line and a data source or sink of this participator or terminal, whereby the counters of all participators or terminals are synchronized with each other. The arrangement includes apparatus to detect short circuits and to shut down individual sections of the bus line to protect the individual sections without shutting down all sections.

摘要:
An arrangement for time-division multiplex data transmission having a data bus system which comprises a data bus circuit, several subscribers which are connected to the data bus circuit and have a transmitter part and a receiver part and communicate with one another by data transmission in a predetermined sequence in a given combination, and at least one clock generator, in which the sequence of all the given combinations of the subscribers runs through during a time frame and a time slot within the time frame is available for connecting each combination. Each subscriber includes at least one programmable counter for emitting a control signal when a programmed number has been reached and for resetting itself to zero when a given counting capacity which is the same for all counters has been reached. The programmable counter has a counter input connected to the clock generator and a first control output. A switching device is connected to the first control output for forming a data-transmitting connection between the data bus circuit and a data source or data sink respectively of each subscriber. Each subscriber has its clock generator. The programmable counter of each subscriber can be reset synchronously with the programmable counter of the other subscribers and can not be subjected at its counter input to clock pulses generated by the clock generator until the programmable counter of a slowest of the subscribers has been reset, which determines the end of the time frame, whereby the programmable counters of all the subscribers are synchronized with one another.
