摘要： A coatings application apparatus pumps liquid paint through a flexible conduit within a rotary variable displacement peristaltic pump to a conventional applicator head. Through constant speed rotating lobes peristaltic action squeezes coating liquid within the conduit through the paint applicator control handle and applicator.The control handle permits changes in the paint flow rate. Upon constriction of the conduit within the control handle, flow rate is reduced, back pressure develops with resulting tube distortion. Distortion levered forces act upon a pre-set loaded pump spring. Variation in pump displacement results. The liquid flow rate within the supply conduit is inversely proportional to the back pressure so developed. If fluid flow is completely arrested by full supply tube constriction, back pressure becomes a maximum and pump displacement becomes zero. The pump continues to operate, however, at constant R.P.M., requiring no high starting torque.The pump unit employes two reverter train speed reduction systems in tandem. A conventional planetary or epicyclic gear system provides a first reduction in R.P.M. The pump rotor element itself, as a secondary reduction unit, allows economy in selection of a high speed, low power, motor drive for the peristaltic pump.
摘要翻译： 涂料应用设备将液体涂料通过旋转可变容量蠕动泵内的柔性导管泵送到常规的涂抹头。 通过恒速旋转叶片蠕动作用，通过涂料控制手柄和涂抹器挤压导管内的涂层液体。 控制手柄可以改变油漆流速。 在控制手柄内的导管收缩时，流量减小，背压产生，导致管畸变。 变形杠杆作用在预先安装的泵弹簧上。 泵排量结果的变化。 供应管道内的液体流量与如此发展的背压成反比。 如果流体流动被完全供应管收缩完全阻止，则背压变为最大值，泵排量变为零。 然而，泵继续工作在恒定R.P.M.，不需要高起动转矩。 泵单元串联使用两个换向器列车减速系统。 常规的行星或行星齿轮系统提供了R.P.M. 作为二次还原单元的泵转子元件本身允许经济地选择用于蠕动泵的高速，低功率电机驱动器。

摘要： A direct current electric motor including a stator assembly having a stator core of magnetic material. The core has therethrough a generally cylindrical cavity and rotatably mounted therein is a cylindrical rotor assembly. Recesses are formed in the wall of the cavity, the recesses defining therebetween motor poles. Coil bobbins are provided, the bobbins being dimensioned to be slidably received in the recesses in positions bounding respective ones of the poles and each bobbin having wound thereon a selected plurality of turns of magnet wire. The length of the stator core and rotor assembly and the number of turns can be selectively varied to provide a motor of desired torque. The bobbins may be molded and provided with integrally formed end portions which close the recesses in the wall of the cavity and provide a cavity having a smooth and continuous cylindrical surface. The motor operates from a source of direct current operating potential and may further include electronic commutating means for alternately and sequentially energizing predetermined ones of the coils in synchronism with the rotation of the rotor. The commutating means is responsive to both the rotation and position of the rotor, permits rotation of the rotor in either direction and includes circuitry which minimizes transient voltages applied to the components thereof.

摘要： An ink supply system for supplying ink to the print head of an ink jet printer includes a pump arrangement having a pump outlet for supplying ink to the print head from a supply tank through a print head supply line. A closed container communicates with the pump outlet and the print head for holding a quantity of ink therein for providing a second flow of ink to the print head at a static pressure that increases linearly with time. A valve controllably actuated by a solenoid selectively directs a portion of the ink from the pump outlet to the closed container, gradually compressing the air therein as the container is filled. Ink is thereby supplied to the print head at a gradually increasing static pressure, facilitating initiation of production of jet drop streams by the print head.

摘要： An electromagnetic rotary actuator including three laminated pole pieces equiangularly spaced about an output shaft. Each of the pole pieces has a bobbin coil wound thereabout. The output shaft rotor is magnetized with four 90.degree. poles. One of the stator coils is utilized as a reference coil and is energized with a DC current. The other two coils are each coupled to a respective drive transistor. The drive signals to the two drive transistors are complementary. The resultant magnetic field set up by the three stator coils interacts with the magnetic field from the output shaft rotor to move the output shaft to a selected angular position.
