Abstract: In the case of hot-rolled strip 11 to be transported between the roughing train and the finishing train on a roller table, the severe cooling losses at the edge of the strip 11 are reduced, according to German Patent 3,001,684, by a cowl-like covering for the edge region. According to the invention, the cooling losses when strips 11 of differing widths are rolled are kept particularly small by adapting the covering to the width of the strip. For the purpose of adaptation, the covering, which is composed of subsections connected to one another in articulated fashion, is given a more pronounced curvature when strips of relatively small width are being rolled and given a less pronounced curvature when strips of a relatively large width are being rolled, this being effected by means of drives which are connected to the subsections. <IMAGE>

Abstract: According to the invention, a heater, in particular an additional heater for vehicles, is provided, in which a sound-damping device is built into the heater. In this connection, a sound damper can be provided in the combustion chamber or the combustion chamber itself can be designed as a sound damper. In this connection, the sound damper can damp the combustion noise and/or the combustion gas noises by absorption and/or reflection. The sound damper can moreover also be designed in such a manner that it simultaneously cleans the combustion gases, for example by catalytic post-combustion and/or by filtering out soot particles when the heater is operated with diesel fuel as liquid fuel. As the sound damper is arranged in the hot zone but not in the flame region of the combustion chamber, it is not acted upon directly by the high flame temperatures, but self-cleaning of the sound damper is nevertheless brought about as a result of the relatively high temperatures, so that it can work reliably and efficiently over long periods of operation. In an alternative embodiment, the exhaust gas is silenced in the exhaust gas collecting chamber before exit from the heater, in order to achieve quiet working of such a heater. An otherwise conventional sound damper situated in the exhaust gas line of the heater can also be omitted. For sound damping, sound-insulating material can be arranged in the exhaust gas collecting chamber. The sound damping can be effected using reflection and/or absorption and/or other conventional methods.

Abstract: In known arrangements for inserting data into a video signal, the clock signals generated in a text generator are phase-locked to the synchronising pulses of the video signal so that the data signals formed in the text generator can be accurately synchronised with the video signal. However, if the video signal has a severe timing error, this can lead to the data signal to be inserted no longer being readable. The novel arrangement is to provide the possibility for the data signal to be displayed without jitter and readably even when the data signal is inserted into a video signal with severe timing error.   For this purpose, the synchronising pulses with timing error are used for forming horizontal synchronising pulses without timing error as reference in the text generator and these are inserted together with the data into the video signal with timing error.

Abstract: Mouse emulation includes two modes, a host mode in which the pointer (62, 64, 66, 68) behaves as the pointer (62, 64) of the host system and an emulating mode in which the pointer (66, 68) behaves as the pointer of the target system being emulated. The display of the target system appears in an emulation window (52) within the host system display (50). The user can switch from host mode to emulating mode by clicking a mouse key when the pointer is located in the emulation window, which also serves to make the emulation window the input focus for receiving user input signals from the keyboard. The user can switch from emulating mode to host mode by depressing a STOP key, a keystroke which need not be provided to the emulator because it would not be provided to the target system's CPU. Mouse related data is transferred to the emulator through a data structure in a reserved memory space which a mouse application does not access, such as the BIOS area if an IBM PC is being emulated. A mouse driver which provides standard responses to service requests from the applications retrieves this data from the data structure, making hardware ports or software emulating or bypassing such ports unnecessary.
