An adjustable die assembly is shown for forming a template having a plurality of holes each having a medial lug portion. The die assembly is mounted in a base member that has a graduated dial plate. The template is first provided with a plurality of starter holes. The die has a post surrounded by an annular recess except for a medial lug portion. The die is first set at a particular angular relationship to the dial plate. A template hole to be processed is fitted over the post. The base member i...

A template promoting the accurate cutting and laying of wall-to-wall carpeting or other floor covering which template is rested on the floor beneath the outer edge portion of the carpet with the template back abutting the wall and with the carpet resting on the upwardly angled front face of said template, said template front face having a longitudinal knife-receiving slot therein whereby a cutting tool can be used to sever the carpet portion thereabove, the distance between the template forward ...

Drafting template adapted to be juxtaposed on a drawing sheet characterized by a plurality of like spaced lands, in a grid or comb configuration, across which a marking implement may be moved, forming marks on the drawing between the lands and leaving voids or spaces therebeneath. Templates for straight and circular broken lines and broken lines of other curvatures are disclosed.

This invention relates to porous, biodegradable materials in which the pore size, biodegradation rate, and pore volume fraction are controlled and within values at which skin contraction rates around an implant-containing wound are delayed or slowed.

Subsea drilling and foundation templates are lowered from a semi-submersible drill rig and levelled utilizing the drill string hoisting apparatus including a heave compensator suspended from the travelling block of the hoisting apparatus, a riser string suspensed from the heave compensator and connected to the template at substantially its center of gravity and further including a constant tension rotary drum air powered hoist supported on the riser string below the heave compensator and having ...

Disclosed is a two step process for automatically finding a human face in an electronically digitized image (for example, taken by handheld digital cameras and digital video-cameras such as cam-corders), and for confirming the existence of the face by examining facial features. Step 1 is to detect the human face and is accomplished in stages that include enhancing the digital image with a blurring filter and edge enhancer in order to better set forth the unique facial features such as wrinkles, ...

A drafting template having printed thereon a pattern of non-concentric elliptical portions, preferably forming complete ellipses, a vertical measuring line extending upwardly from a common point for the pattern or from a base point for the vertical measuring line, and a horizon line mounted at a scaled height above the base point and being parallel to the major axes of the elliptical portions or ellipses. The pattern is a perspective view of concentric circles or portions thereof taken at a scal...

A biodegradable, bioresorbable, three-dimensional template for repair and replacement of diseased or injured bone which provides mechanical strength to bone while also providing a guide for growth of bone tissue. Preferably, the template is formed of biodegradable materials, for example, poly(L-lactic acid), poly(D, L-lactic acid), poly (D, L-lactic-co-glycolic acid), poly (glycolic acid), poly (.epsilon.-caprolactone), polyortho esters, and polyanhydrides, and has the capacity of being rendered...

New methods are provided for the amplification of a midivariant DNA containing an inserted target specific nucleic acid sequence(s) to enable detection of the presence of a target nucleic acid sequence in a test sample. One method employs midivariant DNA as a template for the synthesis of RNA catalyzed by QB replicase. Two midivariant DNA/probe conjugates including a nonreplicable portion of midivariant DNA and a target specific nucleic acid sequence (probe) are described. An amplification metho...

Apparatus for and method of making templates and the like wherein each stack of blank sheets is supported in raised position on a support platform and the space between the stack and the platform serves as a channel through which air is caused to flow in such volume and velocity as to remove the debris formed when template or similar openings are cut in the blank sheets by one or more cutting tools. Either the support platform or the cutting tool carrier or both may be controllably shiftable on ...
