Abstract: An anti-theft device for audio equipment which is accessible through an opening in a frame of an automotive vehicle, includes a rectangular sliding door movable in a vertical direction between a closed position in blocking relation to the opening and an open position permitting access to the audio equipment through the opening; a trackway which guides movement of the sliding door between the open and closed positions; a lead screw rotatably connected with the frame; a support nut connected with the sliding door for threadedly receiving the lead screw; a first gear fixedly mounted on the lead screw; a motor secured to the frame and having an output shaft with a second gear at the free end thereof, the second gear being in meshing engagement with the first gear; an actuation switch for selectively actuating the motor only when the ignition switch of the vehicle is on, to cause the sliding door to move along the trackway between the open and closed positions.

Abstract: Substituted cinnamyl-2,3-dihydrobenzofurans and analogs were prepared from the nucleophlic substitution of a cinnamylhalide with a 2,3-dihydrobenzofuran anion or an analog thereof. These compounds were found to be potent topical anti-inflammatory agents.

Abstract: Thiazole derivatives have been made, for example, by reacting a 2-aryl-2,2-dialkoxyethylamine with an appropriately substituted aryl acetyl halide followed by treating the resulting amide with diphosphoryl pentasulfide. The thiazole derivatives are found to be effective immunoregulants.

Abstract: Substituted 2-benzyl-mercapto-imidazoles and analogs were prepared from the nucleophlic substitution of an appropriately substituted benzoxyacetate with a 2-imidazole mercapto anion or an analog thereof. These compounds were found to be anti-inflammatory agents.

Abstract: Substituted cinnamyl-2,3-dihydrobenzofurans and analogs were prepared from the nucleophlic substitution of a cinnamylhalide with a 2,3-dihydrobenzofuran anion or an analog thereof. These compounds were found to be potent topical anti-inflammatory agents.

Abstract: [(2-Hydroxy-5-alkoxyphenyl)methylthio]phenylmethanol and derivatives thereof were prepared from an appropriate 2-hydroxy-5-alkoxybenzaldehyde with a hydroxymethylthiophenol. These compounds were found to be potent anti-inflammatory agents.

Abstract: Substituted 5-hydroxy-2,3-dihydrobenzofuran and analogs such as the substituted 6-hydroxy-2,3-dihydrobenzopyrans were prepared from an appropriately substituted (5-hydroxy-2,3-dihydrobenzofuran-6-yl) formaldehyde or analog thereof with an aryl amine followed by reduction. These compounds were found to be potent topical anti-inflammatory agents.

Abstract: Phenylthiomethyl-6-hydroxy-2,3-dihydrobenzopyran and analogs thereof were prepared from an appropriate (6-hydroxy-2,3-dihydro-benzopyran-7-yl) formaldehyde or analog thereof with a substituted thiophenol. These compounds were found to be potent anti-inflammatory agents.

Abstract: Substituted cinnamyl-2,3-dihydrobenzofurans and analogs were prepared from the nucleophilic substitution of a cinnamylhalide with a 2,3-dihydrobenzofuran anion or an analog thereof. These compounds were found to be potent topical anti-inflammatory agents.
