Abstract: A hand surgery operating table connectable to a conventional main operating table and consisting of a forearm support that is rotatable in a horizontal plane as well as pivotable about a horizontal axis, further comprising a base plate carrying a hand support; and up to seven flexible and tensionable arms secured at one end to the base plate and carrying finger-fixing thimbles at the other end. The tension of the arms can be adjusted to any desired extent so that they can either maintain their tensioned fixed position or they can be readily displaced therefrom without having to manipulate their tensioning mechanism.

Abstract: The hip prosthesis according to the invention is a further development of the prosthesis formed with conventional head provided with spherical surface, neck and stem, where a guide profile is formed along the outer straight side of the stem, containing components parallel with the side. The guide profile fits the inner surface of the medullary cavity nail, which allows the simultaneous use of the hip prosthesis and the medullary cavity nail, and nailing of the already prosthetized, then fractured femur.

Abstract: The restraining and supporting device for the head of a patient comprises a head immobilizing contraption connected to the operating table, arm and hand supports for the surgeon, wherein the hand supports are fixed to the head immobilizing contraption through flexible arms, also provided with elements releasing or tightening the flexible arms, which elements are fitted to one of the fingers of the surgeon's hand, or interconnected with hand and/or foot switch. The head immobilizing contraption consists of nape support provided with a three-point bearing for the head and can be set at an adjustable height. A front support clamps down the head into the nape support and is connected to the nape support through a hinged mechanism. The flexible arms are attached to the front support of the head immobilizing contraption.

Abstract: Apparatus for measuring braking actions of an automotive vehicle wherein the braking power is measured between the ground and a braked wheel of the automotive vehicle, and wherein data required for identification of the automotive vehicle are recorded, this process being characterized in that for each wheel (7), the weight resting on the wheel is likewise measured, and that further parameters of the braking action are calculated on the basis of the measured values. The apparatus comprises a braking power test stand, and a computing unit, with storage, indicator and/or recording units. The apparatus also has weight measuring units (1), and an output of each of the braking power test stand (6) and of the weight measuring units (1) is connected to inputs of the computing unit (10). An output of each of the computing unit (10) and the storage unit is connected to a respective input of the indicator and/or recording unit (11).
