Dr Raj C Thiagarajan ATOA Scientific TechnologiesDisclosed herein are connectors for panels. In one embodiment a panel connector comprises, a connector comprising a rib-hinging geometry, wherein the rib-hinging geometry comprises living hinges, and wherein the rib-hinging geometry is capable of expanding in area. In another embodiment, a panel ass ...
A surgical chisel is formed by a flexurally rigid chisel shank and a thin, elongated chisel blade fixed at its front end, which are both displaceably guided in slideways in a chisel guide, which lends the chisel blade buckling resistance.
A coated abrasive having a backing and an abrasive layer coated on the first major of the backing, wherein a cross-section of the abrasive layer normal to the thickness and at a center point of the thickness has a total cross-sectional area of abrasive agglomerates which is substantially the same as ...
Self drilling anchors and related methods and apparatus. In one embodiment an apparatus comprises a drill bit, a hammer mechanism for hammering the drill bit in a first direction and in a second direction, and a selection mechanism for controlling whether, at a given point in time, the drill bit is ...
An impacting tool in which a massive hard carbide element is fitted to a steel holder which is reciprocated to drive the element against a formation to be broken. The massive carbide element can be press fitted in the steel holder or shrink fitted therein or brazed thereto and, furthermore, the carb ...
An improved semiconductor wafer carrier provides gimballing motion of the wafer to dynamically align the wafer to a polishing platen. This gimballing motion is achieved by providing a conical receptacle which has a spring friction fit with a spherical button. A torque plate with spring fingers provi ...
A hammer drill has a mode change-over mechanism including a change link with a horizontally elongated slot, an eccentric pin projecting from a mode selector switch and penetrating the slot. The change link is moved vertically by rotating the mode selector switch, which in turn vertically moves a pai ...
A hand-held tool for use as a powered drill or screw driver, has a chuck for holding a tool bit, and the chuck is replaceable without employing another tool. A conically shaped shaft section on a rotary spindle fits into a conically shaped bore in a socket section of a part of the chuck. The shaft s ...
The invention provides a power tool including a tool body and a handle mounted on the tool body at an upper vibration isolation joint and a lower pivot joint. The lower joint permits pivotal movement of the handle relative to the tool body while giving an operator lateral stability and torsional con ...
A hammer drill or chipping hammer includes a housing, a striking mechanism movably displaceably mounted within the housing, and a handle spring supported on the housing. To absorb vibrations generated during operation of the drill or hammer, piston-like weighted members are slidably mounted in the h ...
