Abstract: A method includes accepting title to real estate by an operating partnership of a real estate investment trust, determining a number of transition units of the operating partnership based on an attribute of the real estate, distributing the determined number of transition units in exchange for accepting the title to the real estate, calculating a value of the transition units based on actual performance of the real estate, and converting the transition units to common units of the operating partnership based on the calculated value.

Abstract: A threaded fastener arranged to engage with a threaded shaft and tighten an object to the shaft by stretching the threaded shaft approximately parallel to its own axis. The threaded fastener is arranged so that when screwed on to the shaft the contacting surface are not parallel, thereby leaving a gap. The threaded fastener further comprises a tilting means of levering the surfaces away from one another and enlarging the gap between the surfaces. The tilting means may comprise an additional threaded shaft being threaded into an additional threaded aperture in the fastener or a ball bearing located in a groove on the surface of the fastened and contacting the surface of the object. The tilting means stretches the threaded shaft without bending the bolt requiring far less torque for stretching than a conventional nut and bolt tightened with a wrench.

Abstract: An improved fastener assembly is disclosed comprising a threaded fastener combined with two disc shaped washer components wherein one disc component is resilient and mounted to relatively rotate with respect to the threaded fastener and other disc component. A dry lubricant material is provided between the disc components to facilitate the relative rotation.

Abstract: The invention provides a closed television system for viewing the pulsed laser beam machining of a workpiece said system including a TV camera tube which, in use, is pointed at the area of incidence of the laser beam on said workpiece, a rotary shutter in the optical path of said TV camera tube for intercepting intermittently the light passing along said optical path, and means for synchronising the pulsing of the laser and the rotation of said shutter so that, in use, said shutter prevents light from reaching said TV camera tube each time said laser is pulsed. The invention can be applied to conventional closed circuit television systems to produce a system for viewing the machining a workpiece with a pulsed laser beam without the bright light produced during such a machining operation permanently overloading the TV camera tube.

Abstract: A device which in normal use restricts relative movement between two members to one direction. Attempted movement opposite to the one direction causes an hydraulic lock to prevent such attempted movement, which also causes wedges actuated by the hydraulic lock to engage in locking co-operation to prevent the attempted movement instead of or in unison with the hydraulic lock.

Abstract: An improved dental instrument for use in cleaning teeth, the instrument having a polishing cup with a self-contained abrasive and a system for automatically supplying a cooling fluid to the polishing cup when the cup is rotated; the cooling fluid serving the additional purpose of lubricating the cup driving mechanism, thereby eliminating the need of packing the driving mechanism in grease and allowing the instrument to be sterilized between uses.
