A vibratory separator having a resiliently mounted housing with a vibratory drive. A screen extends across the housing and a cover is positionable over the screen. The screen includes a discharge port therethrough aligned with a discharge passage for removing material from the top of the screen from the system. Another discharge passage cooperates with a manifold plate extending across the separator beneath the screen. An access port is provided through the cover and arranged to receive a discharge plug which can selectively close the discharge hole through the screen. In operation, separating or dewatering is first accomplished, the energy level of the vibration is reduced and a vacuum is drawn above the screen. Bleed air is allowed into the separator below the screen with a restricted flow so that a vacuum can be drawn. Once the material has dried, the vibrational energy can be increased and the plug removed from the hole through the screen. The process material may then be discharged from the unit.

Screening system

A screen tie-down for a vibratory separator has a pedestal with a base plate and a post. The post has internal right hand threads for engaging the screen center support stud, and external left hand threads. A jam nut is threaded onto the support stud against the top end of the post. A cap having internal threads is turned onto the external threads of the post. All adjustments to the pedestal height can be made from above the screen and the tie-down cannot be overtightened.

Separator screen tie-down

A counterweight assembly on a vertical, rotatably mounted shaft which is adjustable. First and second eccentric weight assemblies are fixed to the shaft. One of the eccentric weight assemblies includes a support fixed to the shaft to extend laterally of the shaft. The support has a ring of slots displaced laterally of the shaft. Two eccentric weights are rotatably mounted about the shaft and have pins extending to the ring of slots.

Adjustable counterweight assembly

A vibratory screening apparatus for dry, very fine material. A vibratory housing is employed with parallel screening elements disposed across the housing and spaced vertically. The lower screening element has a much finer mesh size than the upper screening element. The housing includes an opening laterally from between the two screening elements for discharge of material not passing through the lower screen. Sliders are positioned between the screens which have a flat lower surface for riding directly on the lower screen and extend a major portion of the distance between the upper and lower screens.

Dry material separator

A degasser system having a central container and degasser tubes extending to the central container. A vacuum is maintained within the tubes and the container by means of a vacuum pump while liquid is extracted from the central container by a pump. A gas cut liquid is drawn into the tubes by vacuum and conditioned to assume a helical path through the tubes. The liquid is then dispersed into the tank where it is allowed to collect. The degasser intake is throttled as a function of the level of liquid within the container. The accumulated gas within the degasser is extracted from a central location in one of the tubes. The pump includes a housing for total emersion of the pump body, dual inlets, straight, radial impeller vanes, multiple volutes and an extended drive shaft to accommodate gas cut mud.

Method and apparatus for degassing liquids

The object of the invention is an improved brief or panty and method of making the same that has porous fabric panels and elastic members that are elastic in all directions. The panty lies flat against the body of the wearer and the fabric panel does not gather adjacent the elastic members. The panty has an hourglass-shaped panel (10) and an elastic member (11) having hourglass exterior margin (21) and interior margin (22) overlying and bonded to the exterior margin of the fabric panel (10). A functional crotch portion (20) is interposed between the elastic member (11) and the panel (10). The panty is manufactured by forming an hourglass-shaped panty blank (10) of elastic material having front (19) and rear (18) panel portions; forming an elastic border member (11) from elastic material; superimposing the border member (11) on the hourglass margin of the panty blank (10) and bonding it thereto; and securing corresponding transverse edges of the front (19) and rear (18) panel portions.
