摘要： A reservoir supplies liquid through a conduit to a nozzle. The liquid is under small or zero static pressure. Surface tension at the nozzle prevents liquid flow when the system is not actuated. A section of the conduit terminating at the nozzle is designed to be capable of conducting pressure waves in the liquid from end to end of the section without the occurence of significant reflections within the section. An electroacoustic transducer is coupled to the liquid in the reflection-free section. When an electric pulse is applied to the transducer it applies a pressure pulse to the liquid sending a pressure wave to the nozzle where it causes ejection of a droplet. The pressure pulse also sends a pressure wave in the opposite direction. The system has energy absorbing means coupled to the liquid and adapted to absorb substantially all of the energy of the latter wave, thus preventing reflections which could return to the nozzle and interfere with ejection of a subsequent droplet. Two classes of energy absorbing means are described: (a) conduit walls of viscoelastic material which deform under the influence of the pressure wave and absorb energy therefrom, and (b) several forms of acoustic resistance elements within the conduit at the inlet end of the reflection-free section.
摘要翻译：储存器通过管道向喷嘴供应液体。液体处于小或零静压。当系统未启动时，喷嘴处的表面张力防止液体流动。在喷嘴处终止的导管的一部分设计成能够在该部分的端部到端部传导液体中的压力波，而不会在该部分内发生显着的反射。电声换能器与无反射部分中的液体耦合。当电脉冲被施加到换能器上时，将压力脉冲施加到向喷嘴发送压力波的液体，在该喷嘴处引起喷射液滴。压力脉冲也向相反方向发送压力波。该系统具有耦合到液体的能量吸收装置，并适于吸收后者波的基本上所有的能量，从而防止可能返回到喷嘴并干扰随后的液滴喷出的反射。描述了两类能量吸收装置：（a）粘弹性材料的导管壁，其在压力波的影响下变形并从其中吸收能量，以及（b）在导管内的多个形式的声阻元件在入口端无反射部分。

摘要： A phonograph cartridge having a dual-stylus assembly of the turret type wherein one stylus is designed to track stereo record grooves and the other stylus is designed to track monaural record grooves. The cartridge housing has a vertical opening therein and a recessed portion at the base of the opening which forms a seat. A turret shaft is supported in the opening and is axially and rotatably movable therein. The shaft has a pair of cantilever stylus support arms attached to its free end. The turret assembly is adapted for rotation to a predetermined orientation in order to selectively place one of the styli in a record tracking position. A spring is provided for biasing the turret shaft axially and upwardly into the seat to releasably maintain this orientation. Two cam surfaces are provided at the base of the turret shaft to operatively engage the sidewalls of the seat such that, upon mere rotation of the turret shaft, the spring bias is overcome to release the turret assembly from its orientation and permit rotation thereof to place the other stylus in a recordtracking position.
