Abstract: An anti-theft device for portable equipment, such as typewriters, personal computers, video recorders and general office equipment, is in the form of a support or stand which has two components that are mechanically joined by one or more recessed tamperproof screws. Each component has an adhesive strip. By means of these adhesive strips, one component is bonded to the underside of the equipment and the other component is bonded to a mounting surface. The two components can be joined together by tamperproof screws, making the equipment very difficult to remove except by means of a special tool designed for the screws. More than one device may be used with an equipment item so as to give adequate balance and support when the item has an irregular underside. Such a situation arises when the underside has a multiple-planar design or contains ventilation holes and calibration access portals.

Abstract: A composition for dyeing material of synthetic aromatic polyamide fibers, including a cationic dye and a dye assistant, which is a mixture of N-substituted phthalimide and an emulsifier. The N-substituted phthalimide is preferably a 2:1 mole ratio of N-butyl phthalimide and isopropyl phthalimide. The emulsifier is preferably propylene oxide and ethylene oxide block polymer, and an anionic surfactant blend and an anionic/cationic surfactant blend.
