The present invention entails a body related teaching kit for teaching children letters of the alphabet, their sounds, and sounds of long and short vowels along with sounds of selected blends. More particularly the body related teaching kit of the present invention includes a sound recording device adapted to play a body alphabet song that relates letters of the alphabet or sounds of various letters to parts of the body. Also forming a part of the body related teaching kit of the present inventi...

Mycotrienin-related compounds called the T-23-VIII and T-23-IX substances. These substances are isolated and characterized by structural formula and other identifying data. These substances are useful in the treatment of tumors.

A chain of plastic bags having zipper-locking profiles is packaged in a rectangular carton in successive layers wherein the profiles of the bags of each layer are aligned generally along a straight line that is oblique with respect to a front wall of the carton, the straight lines aligning the profiles of successive layers following a zigzag course, which oscillates between the front wall and a back wall of the carton.

3-Amino-2-hydroxy-4-phenylbutanoic acid and esters thereof as well as new derivatives thereof which are related to bestatin in their chemical structure are active to enhance the immune response in living animals.

A metal diaphragm valve including a multiple ply metal diaphragm structure comprised of a plurality of thin circular metal elements each having a planar annular rim surrounding a dome-shaped interior portion superimposed one on top of another with their annular rims fixed together to seal the hollow interior portion of a valve bonnet. A diaphragm contacting surface including at least two areas of different degrees of curvature, one of which is cruciform in shape, is mounted for axial movement in...

A stilbene, e.g., cis- and/or trans-stilbene or a substituted stilbene, is oxidized at an elevated temperature to produce benzophenone and a related product. Diphenylacetaldehyde, also produced, can be converted under the conditions of the invention to produce additional benzophenone. The reaction is effected at a temperature in the approximate range 50.degree.-600.degree.F, preferably 200.degree.-400.degree.F under a pressure of oxygen of from about 1 to 500 psig, preferably 20 to about 200 psi...

A coupling for establishing structural continuity between two angularly related beams, and in particular roof rafters and the like, and comprised of identical complementary members and each fabricated from rectangular sheet partially sheared and formed along a line to establish an angle with a bearing plate and flange plate for engagement with overlapped beam ends respectively, and bent along parallel lines angularly disposed to the first mentioned line to establish a strap plate integral with s...

Dibenzobicycloalkane amines, their pharmacologically acceptable addition salts, intermediates for their preparation, and process for their use. The compounds of the invention exert analgesic activity.

In a marking apparatus and method for books, double sided tabs have adhesive so that the tabs may be adhered to pages of books, with a number-bearing portion of the tab extending from the page. Adhesive occupies one-half of one side of the tab, and numbers are written in opposite directions on opposite sides of the tab so that the tab may be affixed to a left or right page of a book to clearly mark the page and the point on the page to which it refers. Learning key cards have numbers correspondi...

Novel heterogeneous silylhydrocarbyl phosphine transition metal complex catalysts and intermediates therefore are prepared by (a) the selective monoaddition of silanes having chlorine, alkoxy or acyloxy groups to an .alpha.,.omega.-diene (b) followed by the addition of a phosphine to the resulting .omega.-alkenyl silanes to form the corresponding silylalkyl phosphines (c) which are then covalently anchored as such or in the form of their transition metal complexes via condensation of their react...
