A surgical screw system for use with implantation rods includes a screw member, a receiver member, a pressure cap and a locking device. The screw member has a shaft and a head with a spherical undersurface and a conical tapered recess. The receiver member has an upper and lower portion, a u-shaped rod receiving channel and an axial bore.

A person can safely descend from a burning high-rise building or the like using an inflatable flying body that has a hollow conical form in an inflated deployed condition, but is deflated and folded into a backpack form in a stowed condition. The flying body includes an upper stabilizing ring, a lower nose structure with a pneumatic damping body, spoke struts extending conically therebetween, a cover skin covering the abovementioned inflatable components to form the conical outer surface and provide aerodynamic braking drag, and gas generators to inflate the inflatable components. A person straps on the apparatus in the stowed backpack form and pulls a handle to actuate the gas generators for inflating the apparatus, whereby the expanding apparatus ejects the person from the building and then orients itself in a nose-down attitude during the descent. The pneumatic damping body damps and dissipates the landing impact energy.

A heat extraction and cooling system which can be attached to the central processing unit (CPU) of a computer for exchanging heat through an enclosure which houses a ducted fan. The apparatus includes a dual section rotary blade system that is driving by a conventional direct current motor. The apparatus also includes a heat conducting base that is placed in thermal engagement with the CPU. Attached to the base is a uniquely configured heat dissipating member which includes a plurality of upstanding heat dispensing fins, a generally conically shaped shroud and is provided with a plurality of apertures for drawing the flow of cooling air through the shroud and past the fins of the heat dissipating member. The dual section rotary blade system pulls air inwardly through the apertured shroud, past the heat dissipating fins and into the hub portion of the rotary blade system. The heat air is then forced into the interior of the uniquely configured, hollow blades which are attached to the hub portion. Each of the blades is provided with a leading edge portion and trailing edge portion having a plurality of small apertures formed therein. As the blades rotate, a negative pressure is formed proximate the trailing edge of each blade and the heated gases are expelled through the small apertures. This provides a jet thrust action to the rotating assembly and causes the heated gases expelled from the hollow blades to expand rapidly thereby producing an additional cooling effect.

A self-supporting roof lighting system that accepts low elevation light and rejects high elevation light may be produced by making arrays of parallel laser cuts through, or partly through, a flat sheet of transparent acrylic, cutting the segment containing the arrays from the sheet, positioning the segment over linear heating elements to soften the acrylic along the lines between adjoining laser cut arrays, folding the segment along the softened lines through the angle necessary to form a multi-faceted structure of saddle, pyramid or higher order form and allowing this structure to cool and solidify to produce a self-supporting angle-selective roof lighting system with an array of light redirecting laser cuts on each facet. The sequence of the method may be changed so that a saddle, pyramid or higher order structure is first formed by folding or moulding transparent acrylic and, subsequently, an array of parallel laser cuts is made in each facet of the structure to produce an angle-selective roof lighting system. A conical angle-selective roof lighting system may be produced by making concentric laser cuts through, or partly through, a disc of transparent acrylic with a segment cut out, softening the laser cut disc and moulding the disc into conical form.

The invention discloses an expanding type clamp used on a lathe and a machining method thereof. A workpiece is usually clamped from outside to inside when being machined on the lathe. However, for a short thin-wall workpiece which has a cone-shaped outer surface, does not have a cylindrical surface and has high requirements for machining accuracy and coaxiality, when machining of one end of the workpiece is finished and the other end needs to be machined, a universal clamp can not meet the requirements due to the fact that the universal clamp is low in clamping force and prone to deformation. The expanding type clamp used on the lathe and the machining method thereof are suitable for being used in the situation that machining of one end of a short thin-wall workpiece, with a small inner diameter and a cone-shaped or angular outer surface and having high requirements for machining accuracy and coaxiality and free of a cylindrical surface, is finished and the other end needs to be machined. A hole of the machined workpiece is sleeved on an expanding type clamping head first, and then the circumference of the clamp expands outwards evenly in a clamping process to stretch the inner diameter of the workpiece to be machined to carry out lathe work. The clamp is loosened after the machining is finished, the expanding type clamping head contracts elastically, and then the machined workpiece is taken down easily.
