Abstract: The invention relates to a traction device intended to be fastened on an extremity of a person with joint trouble and comprises a base material (1) on which a number of pockets (2) meant to carry weights are arranged. According to the invention the device is so designed that the base material (1) reaches essentially around the whole of the extremity, so that the device by its own force can be kept in place on the extremity without tendency to slip down. The pockets (2) are placed at regular distances from each other around essentially the whole of the device. Further, the pockets (2) are oblong and have a direction that is principally perpendicular to the longitudinal direction of the device. The traction is brought about by the putting of one or more thin weights into each pocket (2), whereby the weights have a shape which corresponds to those of the pockets (2).

Abstract: An improved radial ply pneumatic tire 30 is described. The improved tire 30 has a first annular surface 23 located between the heel 22B and toe 22A of each bead 33 and a second surface 24 extending radially outwardly from the bead heel 22B. The first surface 23 is designed to be in contact with the bead seat 42 of the design rim 40 when the tire 30 is mounted and inflated to normal pressure. The first annular surface 23, when the tire 30 is unmounted, forms an average angle .beta. with the axis of the tire, when the beads 33 are axially spaced a distance D equal to the design rim width as defined herein. The average angle .beta. is in the range of at least one-half degree and less than three degrees greater than the angle formed between the mating bead seat 42 of the design rim 40 and the axis of the tire. The second surface 24 is designed to be in contact with an annular flange 44 portion of the design rim 40 when the tire is mounted and inflated to normal pressure.      The second surface 24 is perpendicular to the axis of rotation.      Preferably the angle .beta. is in the range of 1° to 2° greater than,the rim seat angle, more preferably the angle .beta. is 1.5° greater. The angular relationships relative to the design rim flange 44 permit the bead 33 to exhibit uniform compression upon mounting to the design rim 40, thereby improving the stiffness and handling characteristics of the tire 30.

Abstract: A low insertion loss, wide bandwidth, microwave switch has a superconducting transmission line that can reversibly go from a superconducting state to a normal state by the application of a DC voltage.  When in the normal state, the switch is "off" and microwave signals are attenuated.  To reduce the voltage necessary to cause switching, the width of the transmission line is decreased.  This decrease is done in a controlled manner so that there are no spurious reflections produced on the line, resulting in a wide operating bandwidth.  Previous microwave switches use other means to switch between superconducting and normal and suffer from disadvantages such as relatively slow switching time, complexity or narrow bandwidths as a result.
