Abstract: An image projecting apparatus is provided to project a real image of an object to be displayed while obscuring the object from view by an observer located exteriorly of the image projecting apparatus. The apparatus includes a housing (12) having an interior and a view area (14) for the real image. First and second reflective surfaces (40, 50), such as mirrors, are disposed in the housing. The first reflective surf (40) must be concave of a variety of geometric shapes. The second reflective surface (50) may be concave or, alternatively, planar. A masking member is interposed between the object and the view area. The second reflective surface can define the masking member. The first and second reflective surfaces are arranged at an acute angle to each other.

Abstract: A safety saw may be used by a child and includes a handle and a forwardly extending blade. The handle has a first portion, a second portion and a waisted portion between the first and second portions. The minimum diameter of the waisted portion is no more than fifty percent (50%) of the maximum diameter of the second end portion. Preferably, the first and second portions have equal radii. The blade has teeth only on one lateral edge, and a distal tip extends forwardly along the longitudinal axis of the blade to a rounded end. The distal tip has a length at least twice the width of a tooth, and it is devoid of any teeth. The leading edge of each tooth is perpendicular to the longitudinal axis while the trailing edge is oblique to the longitudinal axis at an angle of about 50° to 60°. The height and width of the teeth may be the same; alternatively, the width may be twice the height.

Abstract: The present invention describes a process for producing 10-deacetyl baccatin III from a solution containing a solvent reactive with hydrazine hydrate and a spectrum of taxanes. The solution is contacted with hydrazine hydrate thereby converting some taxanes therein into 10-deacetyl baccatin III. The process can target taxanes having an ester functionality on at least one of the C-10 and C-13 positions. The hydrazine hydrate cleaves the ester functionality of the taxane solute, The process may be used to produce 10-deacetyl baccatin III from a biomass extract by contacting the biomass extract with a mixture of a solvent and a hydrazine hydrate. The solvent may have a functional group that is cleaved by hydrazine. Acetate solvents are contemplated.
