Assignee:

Wheelabrator-Frye Inc. - Hampton NH

International Classification:

B24C 506

US Classification:

51434

Abstract:

A bladed centrifugal blasting wheel formed of a pair of spaced parallel wheel plates having a central opening through which blades are inserted into grooves extending radially from the central opening through the adjacent surfaces of the wheel plates, improvements including means for locking the blades between the wheel plates, impeller and control cage means for feeding particulate material onto the ends of the blades with centering means forming a part of the impeller for locating the elements in the central opening, resilient means adapted to be engaged by the blades upon insertion for holding the inserted blades during assembly, indicator means for showing the position of the control cage and means for providing air curtain to prevent accumulation of stray or rebound abrasive in the hub seal area during rotation of the bladed wheel.

Assignee:

AptarGroup, Inc. - Crystal Lake IL

International Classification:

B65D 5502

US Classification:

215237

Abstract:

A closure is provided for an opening to a container interior. The closure has a base for attachment to the container at the opening and defines a discharge aperture communicating with the opening. A lid is hingedly connected to the base for movement between a closed position occluding the aperture and an open position away from the aperture. A manually releasable latch is defined cooperatively by the base and lid to hold the lid closed. The lid has an outwardly projecting engaging member whereby the user can release the latch and apply a force to the member to lift the lid via the member.

International Classification:

B24C 506

US Classification:

51435

Abstract:

A centrifugal blasting wheel includes a pair of front and back wheel plates interconnected in spaced parallel relationship. Each wheel plate has a central opening defined by an annular surface of constant diameter. These plates are provided with respective cross-wise aligned grooves in their inner faces extending radially in equally circumferentially spaced relationship from the inner annular surfaces of the plates to the outer annular surfaces thereof and opening into each of the annular surfaces. A blade is removably mounted between each pair of aligned grooves. Each blade has a body generally in the form of a parallelepiped with an inner and an outer end and side flanges to define a blade of I-shape in transverse cross-section. Each blade has at least one retaining lug extending laterally from one of the side flanges and being substantially closer to the inner end of the blade body than the outer end thereof. Each such lug is provided with a curved, non-planar, smooth and uninterrupted abutment surface arranged to be in substantial co-extensive engagement with a portion of the inner annular surface of the adjacent wheel plate when the blade is operatively positioned between a pair of the grooves.
