Abstract: A lubricant seal having no wearing surfaces is provided with a partition plate having a gutter portion and a slinger supported in a labyrinth cavity. This lubricant seal is particularly useful in larger seal applications where the wear of the rotating shafts exceeds the wear characteristics of available seal material. Migrating lubricants are captured in the gutter portion of the partition plate and are directed through the gutter portion around and below the shaft where the lubricant is returned through a drain to a sump.

Abstract: A structure and a method of making a burner box by providing a U-shaped body with end members. The end members each rest on an end of the body and of the U-shape body. The ends are welded to the end members to the U-shaped body by a tungsten arc gas welding process whereby the end members are welded to the U-shape body and the edges are catalyzed in the weld. The end members overlaps the U-shape body by about half the thickness of the body to provide a filler material for the weld. A tab is integrally attached to each side of each of the end members. The tab rests on flanges and are catalyzed in the weld.

Abstract: A process and a structure is described for separating particles in a fluid medium based on a difference in settling velocity. The feed is introduced tangential into the separation zone. The tangential feed system includes a transition box to reduce flow velocity and disperse the slurry across the separator eliminating the efficiency losses associated with other classifiers that introduce feed directly into the separation chamber. This approach offers an improvement in process capacity and efficiency. The fluidization water is introduced to the separation chamber below a baffle plate that disperses the water across the base of the separator. The feed system may include baffles in the upper separation chamber, and a stilling well with an impact plate adjustable side walls and adjustable baffle plates to reduce flow velocity and disperse the slurry across the separator.

Abstract: An electronic enclosure having a cover and a base member reduced in height by providing the necessary height on the decoupling area around and generally in the same vertical space as is occupied by the thickness of glass provided to hermetically seal the enclosure. The glass is formed inside and kept away from the decoupling area by an inner ring fixed to the base member, or by a tool which is removed after the glass has been applied to seal the enclosure.

Abstract: A returnable reusable container which may be quickly assembled to contain a product and quickly disassembled to a substantially flat condition for storage and return shipping when empty. The container has a rigid member extending around its upper perimeter to prevent twisting of the container. This member has locking means to hold the container in an assembled position, and which unlock to allow the disassembly of the container. The locking means when engaged restrains relative movement at the corners in all directions except the direction required to disengage the lock. When the flaps are fixed to the sides of the container, relative movement at the corners is restrained in all directions.

Abstract: A spirit level having a sub-assembly on the body. The sub-assembly has a vial holder having two spaced pockets. A curved vial having two ends received in the pockets and resilient ribs having a curve matched to the vial and engaging the vial to hold the vial in an adjusted position. Each vial can be adjusted relative to a separate vial holder and each vial holder/vial sub-assembly can be independently adjusted and set relative to an appropriate edge of the level. The vial snaps into a fixed receptacle on either side of the vial holder. One side of the holder is curved to match the curve of the vial to insure that the vial is properly positioned. The underside of the vial holder may be relieved to increase flexibility to make it easier to snap the vial into place.

A partitioned product hopper collects metallic fragments separately from the bulk slurry flow. A spray bar is provided to clean the drum.

Abstract: The invention provides a hydraulic swivel connector, excavating machine having hydraulic swivel connectors and methods of use thereof. The hydraulic swivel connector, comprises, a first and second hydraulic swivel cylinder each having an extendable arm, a swivel connector frame, a swivel connector rotatable member. One end of each hydraulic swivel cylinder is connected to the swivel connector frame. The other end of each hydraulic swivel cylinder is connected to the swivel connector rotatable member. Extension of one hydraulic swivel cylinder arm forces the swivel connector rotatable member to rotate in a first direction, and extension of the other hydraulic swivel cylinder arm forces the swivel connector rotatable member to rotate in a second direction.

Abstract: A method of filling containers with bulk material wherein a bag is filled, weighed and densified at the same time. The bag is supported on a releasable hanger. The bag is constantly weighed, and a predetermined quantity of material is placed in the bag. The bag is raised and lowered and vibrated to settle, or densify, the material while the material is being admitted to the bag. The bag may be vibrated while being filled by counter-rotating vibrators. The material is weighed and the net weight is determined. The method of the present invention can be used for filling drums, boxes and other containers, as well as bags. Specific designed power operated hooks are used to support the bag. The containers are supported on a platform. Drums as well as bags can be filled without any change in the machine requiring tools. A three piece spout is used to fill bags and a drum head adapter is supported on the spout to fill drums.

Abstract: A coupling for connecting a hose to a container. The coupling is made up of a tubular body that telescopically receives a ferrule. The coupling has a stop flange with diametrically spaced recesses and the ferrule has diametrically spaced inwardly extending projections that pass through the recesses in the stop flange when the ferrule is inserted onto the coupling. The ferrule is then rotated so that the projections overlay the stop flange and prevent the ferrule from being removed during shipment or storage of the couplings. The ferrule can be swaged or crimped to the hose for holding the hose to the coupling in the conventional manner.
