Abstract: The invention relates to a device for blood pressure measurement with a sleeve (15) which is to be secured to the arm and which exhibits a pulse sensor (18), a pressure source (25) connected to the sleeve (15) and a pressure measuring device (29) to measure the pressure in the sleeve (15), according to the invention the sleeve (15) being adapted to the region of the wrist and being padded over the back of the hand with a bridge (16) protecting the veins (13), and an inflatable bellows (17) being provided in the region of the artery (14) at the inner surface of the wrist. In this case, the bridge (16) can be a cushioned half tube. The bellows (17) can be connected to the pressure source (25) via a switchable valve (24); in this case, the valve (24) is cut off as a function of the signals of the pulse sensor (18). Finally, in order to measure the systolic pressure it is possible for the valve (24) to be controlled so that upon the occurrence of pulse signals it continuously connects the pressure source (25) to the bellows (17) and upon failure of pulse signals it lets the pressure out of the bellows (17). Finally, in order to measure the diastolic pressure it is possible for the valve (24) to be controlled so that upon failure of pulse signals it continuously connects the pressure source (25) to the bellows (17) and upon occurrence of pulse signals it lets the pressure out of the bellows (17). <IMAGE>

Abstract: Motor vehicle transmission control systems with a drive motor, power-shift transmission and a torque converter connected between them, operating with adjustable stator blades or a modulation coupling, the torque converter being adjusted by a control unit to which is applied the power-shift transmission pressure, should be of simple construction and reliable and should have a short slipping period with only a slight increase in heat. This object is achieved here in that the adjusting motor for the torque converter and the power-shift transmission (1) are located in each case in one hydraulic circuit (4, 8) and a hydraulically operated control unit (6) is included in the power-shift transmission circuit which at the same time controls the flow of the pressure medium through the adjusting motor circuit (20). <IMAGE>

Abstract: Disclosed is a tubular casing of fiber-reinforced regenerated cellulose comprising a film web which is curved to form a tube. The edge regions of the film web, which run parallel to the longitudinal axis, abut or overlap slightly and are sealed by means of a film strip which covers both the edge regions. The film web and the film strip composed of the same material have, in the wet remoistened stage, a breaking strength of about 15 to 30 N/mm2 and an elongation at break of about 30 to 50% in the longitudinal direction of the web, and a breaking strength of about 15 to 35 N/mm2 and an elongation at break of about 30 to 50% in the transverse direction of the web. The breaking strength in the transverse direction of the web is equal to or greater than that in the longitudinal direction of the web. The adhesive layer is smoke-permeable and is preferably composed of a material system which sets without a chemical reaction. The film web is produced from viscose, and it is prevented from shrinking during the process and is stretched in the transverse direction during drying. The tubular casing finds particular application as a sausage casing.
