A cake cutter is disclosed that has a vertical blade with an outline of an isosceles triangle. The base wall of the blade is in two parts, a handle beign affixed to each part, the two legs of the handle being joined by an arcuate spring section.

A cutting utensil for flat, round foodstuffs comprises a cruciform blade mechanically coupled to a shaft and handle for pushing the blade into the food. A housing encloses the upper and top surfaces of the blade and is coupled to the shaft and handle via a spring so that after cutting, the blade will retract back to a resting position within the housing. In the preferred embodiment, the cruciform blade has eight arms for cutting eight equal sectors, and the housing is star shaped with blade arms...

This invention relates to newly identified compounds for treating and preventing tumors and cancers, and methods for treating proliferative diseases associated with the imbalance or inappropriate activity of tyrosine kinases implicated in proliferative diseases.

The preparation and use of organometallic complexes of Group III metals having the formula: wherein Me, Ar, X and R are as defined herein, to stereospecifically polymerize unsaturated monomers is provided.

An anchor comprising an exterior bale and having two fluke planes in a horizontal plane that lie vertically parallel and in a horizontal plane are separated by vertical ribs uniting the horizontal planes at an angle of 90.degree. and forming with them open spaces between the fluke planes that allow the passage of marine floor material through the entire length of the fluke planes area. Stops elements are to either side of the fluke plane and control the burial angle rotation of the fluke in rela...

A boron/carbon fiber 1D laminate comprising a boron fiber layer and a carbon fiber layer having a balanced pair of carbon fiber plies embedded in a plastic resin matrix has a coefficient of thermal expansion between .+-.0.54 .mu.m/m/.degree.C. and a specific modulus greater than 8.9.times.10.sup.6 meter. A 2D boron/carbon fiber quasi-isotropic laminate having two sets of quasi-isotropic boron fiber plies, two sets of quasi-isotropic carbon fiber plies, the laminate has a Coefficient of Thermal E...

A grapnel anchor having an elongated shank with a fixed arm at its lower end and several movable arms mounted on the elongated shank. Each movable arm is mounted on the shank by a polygonal hole in the center of the arm. The upper end of the shank is enlarged to prevent removal of the movable arms from the anchor's shank. The upper portion of the shank beneath its enlarged upper end is a cylinder sized to permit each of the movable arms to rotate about the upper cylindrical portion of the shank....

A flying insect swatter which includes a plurality of cutting elements arranged in a grid-like array. Adjacent cutting elements are spaced apart by a distance less than the wingspan of a flying insect but far enough to permit air to pass freely between the elements without creating an appreciable pressure wave ahead of the cutting head. The cutting elements are adapted to cut insects into pieces which pass between the cutting elements when the head is swung through the air. In the disclosed embo...
