Abstract: A shielding device with a shielding component (17) forming a shield surface, a heat shield in particular, has a clamping component (1) formed to be integral with the shielding component (17) by an extension. The clamping component is folded onto itself at a bending point (29). Two clamping legs (31, 33) are positioned side by side and form the clamping surfaces facing each other to delimit a clamping gap (35) with one end closed at the bending point (29).

Abstract: Several video cassette recorders are among studio video equipments operated from a control unit at a control desk as a cluster of studio video equipments interconnected by a coaxial line constituting a digital data bus. The video cassette recorders have simple addresses and the control unit has a multiplicity of addresses which are all recognizable at the video cassette equipment as an address for the control unit. In starting an operation a return address is selected at the control unit and stored therein so as to exclude normal responses or notifications from the recorders directed to that address, while that address is supplied to a selected video recorder as the source address of an initial communication to the selected video recorder. That address is stored in the selected video recorder as the address for response to the control unit.

Abstract: A graphics display in the form of special effects recording, displayed on a monitor in real time in synchronism with the sensing and internal control signals utilized for the operation of the threading and unthreading as well as cassette loading and unloading in a videotape equipment, displays the course of the tape in all stages in simple graphics which can illustrate any malfunction. In the case of a failure the last normal position of the tape is stored.

Abstract: In order to couple together vertical-frequency synchronization signals generated by a computer connected to an data transmission system, the synchronization signals are generated by counting the clock pulses. A reference signal is transmitted to the computer or processor; the reference has a frequency which is a whole-number fraction of the desired frequency. Upon receipt in the processor (16) of the reference signal, a counter (19) provided for counting of the clock pulses is preset.
