Abstract: Described is a method and device for conserving organs, body extremities and pieces of body tissue by means of an extracorporal circulation system. Conservation is carried out at room temperature or body temperature. Long-term conservation is carried out using three discrete circulation systems, the first supplying the organs, extremities or pieces of tissue with an aqueous physiological nutrient concentrate or with blood or with a blood product. The oxygen is physically dissolved and supplied through a dialysis membrane by the second circulation system, metabolite exchange and detoxication also taking place at this membrane. The third circulation system cuts in automatically, under timer control, to flush out the tissue. During flushing, circulation system (1) and (2) are switched off in order to avoid the liquids mixing with each other. The various elements of the device are connected up by means of disposable tubing or tubing made of sterilizable material.

Abstract: A fastening arrangement for guide rails of pull-out guides for drawers within the carcase of cabinets which have a narrow opening in the front relative to the interior width between the side walls of the carcase, the guide rails having a length which is less than the depth of the carcase. An extended metal distance profile having a length greater than the distance between the end of the guide rail while in its installation position at the front end of the carcase and the rear wall of the carcase is provided at the end of the guide rail. The distance profile is brought into an overlapping position with the guide rail and bridges the distance between end of the guide rail and the rear wall. The end of the distance profile, averted from the guide rail, is installed in a metal holding fitting provided at the rear wall of the carcase. The guide rail is connected to the distance profile in the mutually overlapping region.

Abstract: A fastening plug for mounting furniture hardware having an expandable sleeve into which an elongated shaft of an expander enters, the shaft having a head for rotating the expander relative to the sleeve. The elongated shaft of the expander has multiple expansion sections along the length of the shaft and which taper in the direction of the protruding end of the shaft. The central bore of the sleeve which receives the elongated shaft of the expander, is shaped so as to complement the shaft, and the position of the complementary, tapering expansion sections of the shaft is varied relative to the complementary tapered central bore sections in the sleeve when the expander is rotated relative to the expansion sleeve.

Abstract: A modular rolling pin has a plurality of cylindrical linking modules and a plurality of cylindrical dough storage modules. The linking modules and the dough storage modules are releasably and interchangeably lockable to each other, and each of the dough storage modules consist of two opposing sections for retaining dough therein. Each of opposing sections define approximately a corresponding half of a generally rounded dough storage space.

Abstract: A measuring device scanning from edge to edge of a continuously fed sheet includes two sensing heads spaced apart from the sheet by air cushions whose thickness is not influenced by pressure of supplied air and is subjected to an invariable approaching gravimetric force. The air cushions are preferably formed of air jets from calibrated holes at the inside of both sensing heads, each of said holes being surrounded by annular barriers with circular rims. While the approaching force applied to the upper head is given by the own weight of the latter, the corresponding opposed force on the lower head is provided by a pressure regulator of internal air at the inside of the lower sensing head.

Abstract: The invention relates to a process for the manufacture of very high-purity antihemophilic factor (FVIIIc) and von Willebrand factor. This process enables the manufacture of very high-purity antihemophilic factor (FIIIc) devoid of the bulk of the Willebrand factor comprises a step for purification by ion exchange chromatography with the aid of a chromatography column containing a gel, the purification step comprising a step for adsorption of the antihemophilic factor essentially devoid of the Willebrand factor on the gel in the column and a step for desorption of the purified antihemophilic factor, which is collected, thereby obtaining an antihemophilic factor devoid of the bulk of the Willebrand factor and having an activity as high as 250 IU/mg of proteins. This process also permits to recover von Willebrand factor in very high purity.

The method includes: dividing the 360.degree. of the rotation into 2.sup.n angular values; generating a coding sequence of 2.sup.n binary configurations made up of 2.sup.n +(n-1) bits; generating a coding pattern wherein said angular values are coded; storing said coding pattern in the transmitters and in the receiver; starting the rotations of the two transmitters at a correlated, constant speed; transmitting the angular data corresponding to the direction of emission of the beams; demodulating the signals detected by the receiver and obtaining the coded angular values; and calculating the vehicle position by using the latest mean angular values obtained from the signals.

Abstract: System for analog-digital conversion of signal using at least two less highly resolving AD converters, each having a different preamplification, wherein the AD converter having the most favorable resolution of the momentary signal is utilized to compute therefrom the digital output signal of the system. The preamplifications do not have to be precisely known, but are determined by means of the digital signals formed by the conversion. Preamplification errors, such as offset errors or transmit time errors, are eliminated by choosing the appropriate computation algorithm.
