Abstract: In a VHS video recorder recording the luminance signal (Y) with increased bandwidth (S-VHS), the bandwidth of the recorded chrominance signals (U,V) is also to be increased. In the free frequency band (1) below the video carrier (BT), a chrominance signal (U or V) is in each case recorded in accordance with the single-sideband method. This increases the bandwidth of the recorded chrominance signals from about 0.5 MHz to 1.0 MHz. In particular, VHS video recorders with increased image quality (super VHS). <IMAGE>

Abstract: The invention relates to a method for producing rust-resistant, angular shot-blasting abrasives (>60 HRC) based on a Fe-Cr-C alloy. According to said method, a granulate consisting of an iron-chrome-carbon alloy is tempered to >60 HRC by subjecting it to a thermal treatment of greater than 900° Celsius in a reduced atmosphere. A stainless, hard material which can be reduced to angular granules is thus produced. This results in shot-blasting abrasives with excellent characteristics for treating the surface of workpieces consisting of stainless material, e.g. stainless steel, non-ferrous metal and natural stone.

Abstract: Pump for the sterile delivery of a heated infiltration fluid into a patient's tissue has a hose roller pump (1), a heater for the fluid taken from its supply bag (16), a sterile disposable hose tube set (2,12,13) and a control unit. All the variable pump data are registered and stored during pumping to be displayed during or after use. Pump for the sterile delivery of an infiltration fluid has a control which sets the total volume of fluid to be delivered and the timed flow rate, and maintains a constant volume flow during the rotation of the pump rollers. The hose tube set has a suction tube, a pump tube and a connecting tube. The pump rollers are spring-mounted. The springs are under a pressure so that they can flex under a given pressure so that the drive rollers of the pump tube cannot press together and block the flow through it. The material for the pump tube has a high flexibility and resists pressure, using a plastic which retains its dimensions and has a strength of 55 Shore +- 5 Shore. The end of the coupling towards the hose tube matches the inner diameter of the tube, and has a conical expansion where the tube is drawn over it in a secure connection. A sleeve is placed over the tube, tightly against its outer surface in a secure fit. The coupling can have two conical sections to take both ends of the tube, drawn towards the center of the coupling in a tight fit, secured by tight external sleeves. The pump is operated by a foot switch. The pump has a mounting for a surgical suction unit, with a release connection between the suction unit and the pump. The pump and the suction unit can be operated by a double foot switch.

Abstract: In fibre-optical transmission in duplex mode using the same wavelength in forward and backward direction, the problem arises that, if an interruption occurs in the transmission path, the transmitter's own transmitted signal appears as a result of reflection in its own receiving element and deceives monitoring circuits provided. To ensure monitoring reliability, the digital signal to be transmitted is converted according to the invention before transmission into a redundant code and at the same time specific code errors which can be detected at the receiving end are inserted at periodic time intervals. In both terminal stations, the received signal is monitored for the occurrence of the specific code errors and an alarm signal is generated if they occur in the receiving element of the transmitting terminal station. <IMAGE>
