Title: Control device for a switching transistor
Inventor: MELAMED ANNA DIPL-ING
IPC: H03K17/06
Filed: 1982-10-07
Granted: 1983-07-28
Abstract: A control device for a switching transistor (3) contains a base control circuit (6) having at least one diode (13), the forward direction of which is polarised in the same direction as the base-emitter path of the switching transistor. Between the control input (7) of the base control circuit (6) and the collector of the switching transistor, a saturation control circuit (8) having at least one diode is located, the forward direction of which corresponds to the collector-emitter path of the switching transistor. To avoid high turn-on losses and ensure a high turn-off speed of the switching transistor, the saturation control circuit (8) is provided with at least a second diode (9) connected in series with the first one in the same direction and is designed in such a manner that the base-emitter voltage of the switching transistor is higher than the collector-emitter voltage approximately by the forward voltage drop of a diode (9; 10) when a turn-on control voltage is applied to the control input. <IMAGE>

Abstract: 1. A device for time or en vent controlled recording of television programme signals, whereby the date of the shcheduled d start of a television programme item, on the one side, can be taken as reference value, e.g. in the form of a visually legible bar code (51) from a program announcement medium (5) and read into a storage device (310) and, on the other side, in a first time-controlled operational mode, is available as a dynamic actual value (outlet 351) from a real-time calendar clock (350) or, in a second event-controlled operational mode, can be taken from the television signal (32) containing the item as actual value (321) static for the duration of the item, characterized in that, into the storage device (310) an exchange flag-bit can be written marking the exchange of a previously announced programme item for another subsequently announced program item and taken from the programme announcement medium containing the later announcement together with the data reference value and that an evaluation device (3) contained in the device (310) is formed such that, in case of enent-controlled operational mode, a) recording does not take place, if at a stored reference-value date no exchange flag bit has been equally stored, and if instead of the date a drop-out identification signal is drawn from the television signal, and, b) time-controlled recording instead of event-controlled recording takes place, which results from the comparison between the reference value date and the actual-value date obtained from the calendar clock (350), if an exchange flag bit is stored together with the reference-value date.

In order to achieve a particularly simple construction which is convenient for assembly, the arrangement is designed in such a manner that the heat exchanger plate stack and the fan units are held in the housing on common supporting elements which are arranged in the regions of the corners of the plate stack and at least have guide devices for the removable plate stack and mounting devices for the fan units, and are connected to the housing.
Patent DE-3609150-C1 (DE)
Title: Shaft line with stuffing box and additional weight
Inventor: BERGERHAUSEN KARL ING
IPC: E21D7/00
Filed: 1986-03-19
Granted: 1987-08-06
Abstract: In order, when directing the weight of a pipe into a stuffing box adjoining a pipe section of a shaft line, to avoid deflection and buckling of the pipe section, caused by a thrust acting on the bottom end face of the pipe end plunging into the stuffing box, and nevertheless to be able to dispense with lateral pipe guides and lifting cylinders a throat is provided above the stuffing box in the strut pipe. The projection surface of the throat causes a tensile force which depends on the fluid pressure prevailing there, is directed downwards and is opposed to the upward thrust acting on the end face of the strut pipe. The said projection surface is selected in such a way that the tensile force achieved always overcomes the friction force in the stuffing box in order to make the pipe section statically stable. If no fluid is located in the line, the tensile force caused by the throat does not appear. In order to nevertheless overcome the friction forces of the stuffing box, even during temperature-induced changes in length of the pipe section, an additional weight is provided directly above the strut pipe. The additional weight causes an additional tensile force which is about 1.5 times the friction force of the stuffing box. <IMAGE>

Abstract: In a process for dyeing silicic acid glass fibres or textiles made from these fibres, with organic pigments, the glass is desized, if necessary, subjected to an acid treatment, dyed, and if necessary coated with a finish preferably impermeable to steam. The acid treatment is applied until an extraction yield of 2 % maximum, preferably 1 %, is attained and, after intermediate drying if necessary, the fibres are dyed with basic acrylic dyes having a K-value of  </=  3.5 and high stability to light in a pH range of 0 to 3 by a single-bath technique for mordants and dyes, if necessary with addition of wetting agents and complexing agents at a bath ratio of 1:4 to 1:15 and a temperature between ambient temperature and 130 DEG C. After dyeing, the fibres are rinsed, neutralized and subjected to further treatment in the usual manner or dried, mordanted at pH 0 to 3, and dyed at a pH corresponding to that of a 0.5 to 2 g/l aqueous solution of acetic acid. The invention also concerns the products so obtained.

Patent DE-3825683-C1 (DE)
IPC: G01N21/45
Filed: 1988-07-28
Granted: 1989-12-28
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).

Title: Automatic cable insulation stripping unit - uses capacitance signal generated by contact of knife edge with cable conductor to limit further closure
IPC: H02G1/12
Filed: 1990-10-19
Granted: 1992-04-09
Abstract: In the automatic stripping of insulation from the ends of optical or electrical cables damage to the cable-core must be avoided.
