    摘要： Transmission and reflection type holograms may be formed utilizing a novel polymer-dispersed liquid crystal (PDLC) material and its unique switching characteristics to form optical elements. Applications for these switchable holograms include communications switches and switchable transmission, and reflection red, green, and blue lenses. The PDLC material of the present invention offers all of the features of holographic photopolymers with the added advantage that the hologram can be switched on and off with the application of an electric field. The material is a mixture of a polymerizable monomer and liquid crystal, along with other ingredients, including a photoinitiator dye. Upon irradiation, the liquid crystal separates as a distinct phase of nanometer-size droplets aligned in periodic channels forming the hologram. The material is called a holographic polymer-dispersed liquid crystal (H-PDLC).

    摘要： A fuel additive system is disclosed which comprises a sensing device for determining the flow rate of fuel into the system and for generating a signal in dependence upon the fuel flow rate, a control system for conditioning the signal to produce a proportional speed of a variable speed motor, a metering pump driven by the motor for dispensing an additive into the fuel flow at a rate proportionate to the speed of the motor, and a valving device for controlling the rate of increase in the fuel flow rate to permit the control system and the metering pump to respond to the variations within an effective response time to substantially maintain a predetermined ratio between the fuel flow rate and the additive dispensing rate.
