摘要： A force measuring device generally comprising a hollow, three-dimensional container defining interiorly thereof at least one chamber is disclosed. The device includes at least a pair of optical fiber coils with the length of the optical fiber on each of the coils being substantially equal. The pair of coils are mounted on opposite sides of a wall of the hollow container and there are means within the container normally exerting a force on the coil mounted within the container. The system also includes an optical interferometer having a pair of legs with means connecting each of the pair of coils in a leg of the interferometer. Radiant energy emitting means are provided for directing radiant energy into the legs of the interferometer and through the pair of coils and radiant energy detecting means are connected to the interferometer.

摘要： A liquid chromatographic method and apparatus is disclosed which employs an improved pump not requiring driven pistons or sliding seals. The pump comprises at least one length of tubing forming a chamber disposed between first and second check valves, controllable heating means to periodically heat liquid in said chamber effective to pump relatively low volumes of liquid from the chamber at relatively high pressures, means for measuring the pressure developed by the pump, and control means to increase and decrease the amount of heat imparted to the liquid to maintain the pump operation at a controlled pressure setpoint.

摘要： A shield which keeps light from reaching a subject's eyes. The shield is permeable, but capable of blocking the transmission of light; and it has an adhesive for removably securing it to the user's face. An accessory usable with the mask to extend its useful life by replacing the shield securing adhesive is also disclosed.
