Abstract: Systems and techniques relating to a microscope storage unit. In one implementation, a storage unit includes a base, a top and multiple receptacles configured between the base and the top. Each receptacle is configured to house a microscope. The storage unit includes multiple charging devices, where each charging device is configured to recharge a battery of a battery-powered microscope. An electrical cord can be electrically connected to the multiple charging devices, and include a plug configured to mate with an electrical outlet to supply electrical power to the charging devices. One or more wheels can be connected to a lower surface of the base.

Abstract: Polyamide monofilaments are provided of greater than about 1000 denier having a formic acid relative viscosity of at least about 60. The monofilaments have a tenacity greater than about 10 gpd, an along end standard deviation of tenacity of less than 0.1 gpd, and a hot air shrinkage at 177.degree. C. of less than about 15%. In another embodiment, the monofilaments have a cured-in-rubber tenacity greater than about 10 gpd.

Abstract: Polyhexamethylene adipamide feed yarn for false-twist texturing by combined draw-texturing processes is prepared by high-speed spinning under controlled conditions to have improved stability, low shrinkage, good tenacity and uniformity. The feed yarn has break elongation and birefringence values particularly suitable for draw-texturing.
