Abstract: Open spool reels (18) of magnetic tape (7) are recorded with a plurality of different programmes interspersed with recordings in a different form (typically as interruptions to the sync track), representing data information concerning the programme material and production history of the recording. The data (6) recorded on the tape (7) is read by a transducer (39) on a cassette loading machine (30) and used to control the operation of the loading machine, identifying the length of tape and the position on the tape where splices between the magnetic tape (7) and leader tape in cassette shells is to be made. The data (6) also controls a label printer (46) to produce a printed label, typically in bar code form, carrying information representing the programme material on the tape loaded into the cassette. This label is automatically applied to the cassette shell as part of the cassette loading operation so that each cassette is securely provided with external easily read information identifying the programme content thereby avoiding the necessity for individual playback of a tape to identify its programme content.

Abstract: The use of insoluble particulate bentonite for thickening or increasing the viscosity of emulsion explosives is described. The bentonite (swellable clay, montmorillonite) is dispersed throughout the emulsion, without dissolving in either phase and without causing crystallisation, by admixture of the powder with the prepared emulsion in a low shear blender. The resulting emulsions have increased viscosity and rigidity which provide higher gas bubble retention and hence longer shelf life.

Abstract: The detection system comprises a sensor (1) and a controller (2) which are connected by two wires (3a, 3b). The sensor can take more than two states as opposed to conventional detection systems. According to this arrangement, for instance, a small leakage current exists even when the sensor is in normal off state, and, therefore, electric current in the range of I1 to I2 flows even in normal off state. On the other hand, electric current of (I3) to (I4) flows in normal on state. When there is a wire breakage, no electric current flows. Conversely, when there is a shortcircuiting, electric current exceeding (I4) flows. Electric current in the range of (I3) to (I4) corresponds to an unstable state which is neither normal on state nor normal off state. Thus, by distinguishing the level of the electric current flowing through the wires, by using suitable electric current level detecting circuit, which of the level classes it belongs to, a state signal corresponding to the result of this distinguishing process can be outputted for self-­diagnosing purpose.

Abstract: An interferometric gas component measurement apparatus has a light source (27), a measurement path (30) which contains the gas components to be measured, a polarizer (11), a double refracting plate arranged with its optical axis at 45 DEG  to the polarization direction, two doubly refracting plates (14, 20) arranged with their optical axes at 45 DEG  to one another and an analyzer (13). The light which passes through the measurement path is concentrated into an output gap (32) and reflected via a holographic concave grid (33) onto a diode row (22). The thickness of the individual plates is so selected that specific linear combinations of the thicknesses result in phase displacements between the beams polarized perpendicular to one another in the plates, with these phase displacements corresponding to the reciprocal of the quasi-periodic line splitting of selected vibration and/or rotation bands of the gas molecules of the gas components to be measured. The output signal of the diode row (22) and the output signal of a rotary position transducer (34) are applied to an electronic evaluation circuit which, at different rotational positions of the rotating plates (14, 20) determines the concentrations (C1, C2, C3) of gases present on the measurement path (30) from the signals received from the diode row (22) (FIG. 1).

Abstract: The invention is based on the object of developing a known analog optical transmission system in such a manner that a multiplicity of television channels can be transmitted at the original frequency without the signals transmitted being distorted in a disturbing manner. The object is achieved by the fact that the RF signal spectrum is supplied to a transmitting-end frequency filter (11) which comprises several part-range filters (12, 13). At each output of the filters, a part-range of the RF signal spectrum is available. Each part-range comprises several television channels. The filters are in each case followed by an optical transmitting device (23, 24) which are followed by one optical waveguide link each (30, 31) which, in turn, are followed by an optical receiving device each (35, 36). The optical receiving devices are connected to one part-range filter each (40, 41) of a receiving-end frequency filter (45). At the output (46) of the receiving-end frequency filter, the RF filter spectrum is present. The drawing shows a block diagram of the analog optical transmission system. <IMAGE>

Abstract: The transmission consists of a four-shaft planet gear transmission and a continuously variable hydrostatic transmission, arranged in parallel therewith, as well as further gearwheels, toothed clutches implementing a plurality of gears in which in each case the hydrostatic transmission causes continuous adjustment of the continuous transmission ratio of the overall transmission, gear change taking place at synchronous speeds, without load and without interrupting the traction force. The special feature is the design of the toothed clutches and the control provided during the gear-changing process with the effect that the engagement of a new gear and the subsequent deselection of the old gear take place without any jump. In addition to this gear-changing comfort, the transmission has a large overall adjustment range for the transmission ratio as well as high efficiency levels.

Abstract: To detect and evaluate the development of foam on or in a liquid, use is made of the conductivity signal (18) of a conductivity measuring device in the foam. This signal is subjected in digital form to a frequency analysis by a signal processor. If a frequency component or a characteristic frequency of the signal spectrum is above a lower limit frequency, this is used as a criterion indicating the development of excess foam. The signal processor furthermore produces the envelope curves (19, 20) of the conductivity signal (18). A further criterion for the detection of foam is that the difference between the two envelope curves exceeds a predetermined limit value. The invention makes it possible not only to detect foam but to evaluate the foaming process at the same time. A control signal can be generated in order to add foam inhibitor to the liquid in metered amounts. <IMAGE>
