Grasshopper escapement illusion of lights rotating at various speeds about three concentric circumferences on the clock's face. The pendulum speeds up, slows down, and sometimes stops, but returns to the correct time every five minutes. Taylor designed the clock to remind himself of his own mortality. A grasshopper-type escapement is used in an entirely new mechanism intended for wristwatches. This new type of mechanical regulator uses flexible structures both in the escapement and the oscillator. A silicon wheel oscillates about 86,400 times an hour, approximately three times faster than in conventional wristwatches. The initial development was done at the Swiss Center for
Controlled internal drug release by AHI Plastic Moulding Company in Hamilton, New Zealand, in conjunction with the Ministry of Agriculture and Forestry (New Zealand). Developmental trials began in 1981. The CIDR-S was licensed in 1986 and the CIDR-G in 1988. Controlled internal drug release Controlled internal drug release (CIDR) devices are used in livestock for the synchronization of estrus. They are T-shaped devices with a silicone-coated nylon core. The silicone coating is impregnated with progesterone. CIDRs are inserted intra-vaginally using a specialized applicator. The flexible wings collapse for facilitated insertion and expand once placed appropriately within the vagina. The expansion of the wings retains
