Abstract: The axial seal (1) is for sealing against fluid leakage between a rotatable shaft and the wall of a fluid container (5) provided with a shaft through passage (3). The static pressure within the fluid container at the shaft through passage exceeds the static pressure outside the container. The seal comprises a sealing ring (8) fitted around the shaft (2).  A rotor (11) is firmly fitted around the rotatable shaft and a stator (10) is firmly fitted in the wall. The stator has a ring-shaped first sealing surface (16) for location against the sealing ring. The rotor has a second ring-shaped sealing surface (17) which locates against the sealing ring. The two sealing surfaces together define a sealing seat (18), which works in conjunction with a radially outwardly facing locating surface (19) on the sealing ring.

Abstract: An omnidirectional motorized wheelchair having front wheels consisting of a pair of free wheels, and rear wheels consisting of motor-operated wheels driven by electric motors independently of each other. This wheelchair can be moved forward and backward, turned to right and left, and turned in a fixed position. The motor-operated wheels are moved pivotally in the opposite directions by a steering unit to set these wheels to face in the lateral direction with respect to the rider. Thus, the wheelchair can be moved in the lateral direction with the rider facing forward, and it can also be turned while it is moved in the lateral direction.

Abstract: This invention relates to a device for dosing and mixing of two or more liquids. According to the invention, the liquids are led to a chamber (26) where they are mixed, an outlet (30) from the chamber being closed at the same time. When the chamber (26) has been filled, the outlet (30) is opened while the inlets (21, 22) for the starting liquids are simultaneously closed, and when the chamber (26) has been emptied, the outlet (30) is closed again and the inlet or inlets (21, 22) are opened. This cyclic process is repeated any desired number of times. The chamber has a variable volume, and changes of the volume are sensed by a sensor (28), which controls the opening and closing of the inlets and the outlets. 
<??>The device for carrying out the method is provided with a mechanical bistable flip-flop device, which in one of its stable positions opens the inlets (21,22) and closes the outlet (30), and in the other stable position closes the inlets and opens the outlet. The shifting between the two stable positions is controlled by the sensor (28). 
<??>Alternatively, the flip-flop device may be arranged to open and close the inlets, while the outlet remains open, and to close the outlet only when the supply of liquids is essentially exhausted. 
<??>It has been found that the invention is especially suitable for use at infusion of a mixture of two or more liquids into a patient.

Abstract: A resource allocation system for indicating the optimum allocation of a resource between a series of demands iteratively processes the probability data for each demand to determine for each of a range of amounts of resource available the optimum distribution of the resource between the demands and the resultant probability of successfully overcoming all the demands. The system may be used to predict the probability of success where there is a limited resource available and a predicted series of demands, but it may also be used to assess non-predicted threats and to determine an updated optimum distribution and resultant probability.

Abstract: The risk of disturbance from children's cries is reduced if the child is subjected to mechanical vibration. This is applied to the child's place of rest by the use of a motor with imbalance. The environmental inconvenience caused by the children's cry is eliminated usually by a vibration frequency which is disturbing in itself but which is attenuated in a known way at the place of rest's contacts with the surroundings. An automatic device for starting when the child cries can be applied.

Abstract: The invention relates to a process for removing in particular a heavy oil deposited on a shore or bank. In part pulverulent burnt lime and in part an aqueous oil absorbent in the form of porous grains or particles is added to the oil, the lime evolving heat by reaction with at least the water content of the oil absorbent, thus reducing the viscosity of the oil, so that the oil becomes liquid and can thus more easily be absorbed by the oil absorbent. The oil absorbent and the burnt lime are preferably mixed with one another immediately before the application to the oil.

Abstract: The present invention relates to methods and apparatus for encryption and decryption, respectively, of digital sound in television. The decryption takes place in two steps. The first step, encryption with running key, is achieved by adding modulo 2 a pseudo random sequence to the digital signal containing a sound information. The pseudo random sequence is preferably generated by a non-linear feedback register initialized by the control word. The second step involves encryption of the control word, thereby being transmitted to the receiver in ciphered form. The encryption is preferably achieved by a microprocessor also performing coding of the control word for forward error correction. The control word in turn is generated by a true random sequence generator. The invention enables an encryption that is secure against breaking without deteriorating the sound quality and also enables efficient handling of the key of the encryption. <IMAGE>

Abstract: The invention relates to a method of motion compensation and elastic deformation in picture sequences in transmission of moving pictures between a transmitter and a receiver, that is a picture coding method in which the pixel values of the picture are determined using a previous picture. In the transmitter, each picture in the picture sequence is divided into triangles by suitably choosing corner points, and the motion between two successive pictures is estimated such that the motion vectors of all the corner points can be established. Information about the corner points and/or the motion vectors is transmitted from the transmitter to the receiver, in which the motion vectors of the internal points of the triangles are calculated using the three transmitted motion vectors belonging to the respective triangle. The pixel values in the corner points of the triangles and in the internal points of the triangles are calculated using the trasmitted and the calculated motion vectors, respectively. Preferably, the motion vectors of the internal points of the triangles are calculated by interpolation.
