Title: Method and device for installing a cable in a cable duct
IPC: G02B6/44
Filed: 1991-07-16
Abstract: The invention relates to a method, a device and a method for installing a cable in a tubular cable duct. In the method, the foremost end (3) of the cable (1) in the duct (10) and subsequent portions of the cable are first accelerated in a short time with continuous supply of further portions of cable from a torsion-free store. Then, from the instant a certain speed v is reached, the cable is maintained at a tension such that, at said speed and tension,  centrifugal forces in bends and inwardly pulling components of tensioning forces in the cable compensate for one another at the position of said bends, the further portions of the cable being supplied at a supply speed such that the part of the cable already fed into the duct can continue to slide on the basis of its mass moment of inertia. The acceleration can be achieved by causing propelling forces to act on the cable upstream of the inlet end (10a) of the duct in conjunction with pulling forces which act at least on the foremost end (3) of the cable (1) in the duct. The magnitude of at least the propelling forces is controlled by adjusting to zero the net transverse force on the cable, in a bend (8; 51) in the cable located beyond the position where the propelling forces act upon the cable in the direction of movement of the cable. Advantages are that much higher installation speeds and/or greater  installation  lengths  in one go are possible.

Title: Method of making bonded or sintered permanent magnets
Inventor: LOGRASSO BARBARA K
IPC: B22F1/16
Filed: 1991-10-08
Abstract: An isotropic permanent magnet is made by mixing a thermally responsive, low viscosity binder and atomized rare earth-transition metal (e.g., iron) alloy powder having a carbon-bearing (e.g., graphite) layer thereon that facilitates wetting and bonding of the powder particles by the binder. Prior to mixing with the binder, the atomized alloy powder may be sized or classified to provide a particular particle size fraction having a grain size within a given relatively narrow range. A selected particle size fraction is mixed with the binder and the mixture is molded to a desired complex magnet shape. A molded isotropic permanent magnet is thereby formed. A sintered isotropic permanent magnet can be formed by removing the binder from the molded mixture and thereafter sintering to full density.

Title: Canoe portaging thwart
Inventor: MILLER ROSS
IPC: B63B35/71
Filed: 1992-07-28
Abstract: ABSTRACT OF THE DISCLOSURE         During the portaging of a canoe by a single canoeist, discomfort may be caused to the shoulders and neck of the canoeist.  The discomfort is due both to the pressure exerted by the portaging thwart on the shoulders and neck of the canoeist and to the rotation of the canoe and hence the portaging thwart relative to the shoulders and neck during the ascent or descent of inclines.  Much of the discomfort is alleviated by the present invention which provides  a portaging thwart capable of  axial  rotation relative  to  a  canoe.    In this way,  relative  to  the canoeist, the portaging thwart remains stationary while the canoe rotates, thereby permitting the canoeist to place the portaging thwart  at the  optimal  angle  to his  or  her shoulders and neck,  independently of the angle of the canoe.  In one embodiment of the invention, the portaging thwart is mounted in bearings attached to the gunwales of the canoe at approximately the mid point thereof.   The bearings allow the portaging thwart to rotate about its axis relative to the canoe.   The axial rotation of the portaging  thwart  in  turn  allows  the  canoe  to  rotate backwards  and forwards relative to the canoeist,  thus enabling  the  portaging  thwart  to maintain  a  constant position relative to the shoulders and neck of the canoeist as he or she ascends or descends sloping terrain.
