  • Vertical type screening machine for granular material
    Patent number: 4645590
    Abstract: A vertical type screening machine for granular material comprises a housing. A rotary drum assembly is rotatably mounted within the housing and comprises a drum having a substantially vertical rotary axis and a helical blade helically wound around a circumferential surface of the drum. A cylindrical screen member disposed between the drum assembly and the housing cooperates with a peripheral wall of the housing to define therebetween a first chamber and cooperates with the circumferential surface of the drum to define therebetween a second chamber. The granular material to be screened is introduced into the top of the second chamber. Upon the rotation of the drum assemby, the granular material introduced into the top of the second chamber is moved toward the bottom of the second chamber by the helical blade and due to gravity.

  • Method of controlling actuator by applying driving pulse
    Patent number: 4644475
    Abstract: A controlling method for pulse application to an actuator using a digital controller.A controlling method of an actuator, wherein a deviation is obtained from a command value and its feedback value, the absolute value of said deviation is determined whether it is larger than the minimum reference deviation corresponding to the dead zone, and only when the absolute value of the deviation is larger than the minimum reference deviation, the actuator is driven by a pulse having an application period proportional to the absolute value of the deviation plus a minimum application period stored in the memory of the digital controller.The minimum application period stored in the memory is increased or decreased and renewed depending on the judgement whether the movement volume of the actuator at each pulse application was under, proper or over.

  • Titanium and zirconium pyrophosphates, their preparation and use
    Patent number: 4634785
    Abstract: The invention relates to a new process for producing titanium IV and zirconium IV pyrophosphates, certain of which are new compounds, and their uses. The pyrophosphates are prepared by reacting a metal tetraester with phosphorus pentoxide, with or without the addition of an hydroxyl compound, such as an alcohol or a phenol. Depending on the molar ratio of the components, the compounds produced may contain cyclic or straight chain pyrophosphate groups and alkoxy groups attached to the metallic ion. In addition to forming new compounds, the process of the invention produces the desired products without difficult-to-separate by-products.

  • Isolator switch with interlock
    Patent number: 4633047
    Abstract: An electrical isolator has an insulated housing with input and output conductors (1, 2) therein. A spring contact (6) is mounted within the housing for movement between open and closed positions. An insulating shroud (15) fully shields that part of the bridging contact accessible through an access opening of the housing. Manually operable pressure applying structure may be operated when the bridging contact is in the closed position to control that contact between a tightened condition applying pressure between the bridging contact and the conductors without the use of springs, and a free condition wherein the contact pressure is reduced. An interlock assembly prevents engagement and disengagement of the operating member with the pressure applying structure unless the bridging contact is located in either the closed or open position.
