Abstract: A bearing assembly includes a lubricated bearing and a thermistor mounted in or adjacent the lubricant flow path through to or from the bearing. The thermistor is in heat exchange relationship with the lubricant and is connected in an electrical circuit so as to operate in the self heating mode to respond to a deleterious change in the flow of lubricant along the path. The rate of flow of lubricant determines the rate of dispersion of heat from the thermistor and thereby determines the temperature of the thermistor.

Abstract: A reproducing apparatus for television signals recorded on a magnetizable record carrier in the form of a tape comprises a rotatable transducer arrangement which for reading television signals which are recorded in adjacent oblique tracks which extend parallel to each other carries two magnetic heads of mutually different azimuth angles, whose azimuth angles correspond to the azimuth angles of the magnetic heads used during recording. In such an apparatus steps have been taken to ensure that during a mode of operation with stationary record carrier or with a record carrier speed deviating from the normal speed each of the two magnetic heads reads a track in which the television signals have been recorded with a magnetic head having the same azimuth angle as the magnetic head reading it. Furthermore, the signal path for the television signals being reproduced includes a delay device for said signals, which shifts the television signals corresponding to the consecutive fields in such a time relationship to each other that, without a phase jump between the horizontal synchronizing pulse trains of consecutive fields, the differences in the time intervals between every two consecutive vertical synchronizing pulses of each field are zero or a minimum respectively.

Abstract: In a device for the melting and measured discharge of a thermoplastic adhesive, the adhesive material is melted within a melting chamber and then flows out through a discharge nozzle. The discharge nozzle contains a spring biased valve body for blocking flow out of the melting chamber until the biasing force is overcome. If the spring fails and cannot return the valve body into position to seal the melting chamber, the discharge nozzle is arranged to prevent the valve body from blocking the flow of the melted adhesive material through and out of the discharge nozzle.

Abstract: An arrangement for monitoring the concentration of potentially explosive substances in gas streams includes a first flame-ionizer and a second flame-ionizer, both ionizers being accommodated in a common chamber which is maintained at a predetermined temperature, such as 180 DEG  C. A common conduit for supplying both ionizers with a fuel gas is provided in the arrangement. A common conduit for feeding both ionizers with combustion air is mounted in the arrangement. Each ionizer is provided with an individual conduit connecting the assigned ionizer with a respective drying chamber of a coating installation. A sample gas stream discharged from the respective drying chamber is fed into the assigned ionizer through a capillary pipe and passed through a flame produced in each ionizer. The electric current flowing between the electrodes in each ionizer shows the concentration of potentially explosive substance in gas streams being tested. The test data obtained in this arrangement are not affected by varying temperatures in the testing equipment.

Abstract: A flaw detection apparatus for detecting flaws at the outer surface of a product, such as a steel bar, wire or steel pipe, which is round in section and produced by the hot rolling, by use of a probe of non-contact type and rotating around the product to be inspected, the apparatus providing a means for suppressing vibrations of an object to be inspected, a means for measuring a distance (lift-off) between the object to be inspected and the probe, and a means for carrying out positional control on the basis of the detection result of the lift-off measurement so that the axis of rotation of probe is allowed to be coincident with the axis of object to be inspected. In a case of using the eddy current inspection for the flaw detection, two coils of standard comparison system are used and a mixed signal of a plurality of frequencies is applied to the coils so that a signal obtained by the probe coils suppresses the signal component caused by the lift-off variation and corrects the flaw signal caused by existence of the signal component, thereby eliminating the influence of lift-off variation and enabling measurement with high accuracy.

Abstract: An arrangement for the accurate filling of analog values can be tested by using a short-duration test protocol for using and analysing all functions of the arrangement, which then automatically returns to the precise status existing before the test protocol was implemented. A time interval of the order of magnitude of one millisecond is reserved for feeding in test pulses, for the settling time and the return of the arrangement to its initial state. The correct return of the arrangement to its initial state before the test is critical so that the generation of a state ambiguity due to programmed hysteresis is avoided in the analog trigger values. An embodiment of an analog trigger module contains a preprocessing circuit (14) which is connected to an analog signal source (16) and to a diagnostic test circuit (36, 41), and a circuit module (10) which receives signals from the preprocessing circuit (14). The module (10) contains several trigger indicators (18, 20, 22) and a circuit arrangement for detecting coarse failures. The diagnostic circuit (36, 41) applies the test signals to the preprocessing circuit (14), both for testing and for resetting the trigger indicators (18, 20, 22). <IMAGE>

Abstract: A multiple disc clutch has a multiple component clutch housing which is adapted for oil lubricating and cooling of the clutch discs and plates during operation. Concentric driven shafts extend into the clutch housing from the rearward end thereof with the inner shaft extending into a driving relation with a counter bore in the forward component of the clutch housing. The outer shaft has a splined outer end on which is drivingly mounted the driven disc hub. The forward end of the hub is piloted in a recess in the forward component of the clutch housing, and a wave washer reacting against another portion of the clutch housing biases the driven disc hub into piloting engagement within the recess. On the driven disc hub are drivingly mounted the driven discs; the latter being interleaved with the driving plates of the clutch. Both the discs and the plates are disposed within the clutch housing. Cooling and lubricating fluid passages are present through the outer shaft and through and around the driven disc hub so that the fluid can reach the discs and plates. A piston in the clutch housing is operated by fluid pressure to cause clutch engagement.
