Title: Disperse methine dyes from 2-amino-5-carbothio-1,3,4-thiadiazole and aniline, tetrahydroquinoline, and benzomorpholine couplers
Inventor: HUNT KEITH
IPC: C09B23/14
Filed: 1983-07-20
Abstract: The title dyes of formulae (I)-(III) are new:   <IMAGE> wherein R1-R10 are each H or specified substituents, R5 preferably being Me, Et, Ph, CH2Ph or CH2-CH = CH2. These dyes are useful for dyeing polyester fiber and its blends, and other synthetic fibers including cellulose acetate, cellulose triacetate, and acrylic fibres. They show marked improvement in one or more properties such as fastness to light, sublimation, crock, wash, ozone, and nitrogen oxide, and pH stability in the dyebath, and show little or no variation in shade or strength at different dyeing temperatures, e.g.. at 110 DEG C. and 130 DEG C dyeings on polyester. The dyes also show improved tinctorial strength over many commercially available dyes.

Title: Vibration or shock isolator
Inventor: PAPADOPOULOS DEMETRIOS GEORGIO
IPC: F16F3/04
Filed: 1986-06-09
Abstract: An isolator (10) includes a load bearing part (15) arranged for deflection against the action of a series of compression springs (21) and tension springs (17) whose axes are pivotal with respect to the axis of deflection. The arrangement is such that the isolator can operate in a range in which an incremental increase in deflection causing compression of springs (21) is such as to result in an incremental decrease in the restoring force of springs (21) resolved along the deflection axis. The tension springs (17) produce an increasing restoring force throughout this range, and the net result is a load/deflection performance in which a region of zero or near zero stiffness of the entire system, along the deflection axis, is provided, bounded by regions of positive stiffness. <IMAGE>
