Abstract: A quadrilateral refuse container (2) comprising a bottom (8) and four sidewalls (6) extending upwardly therefrom and terminating in an upper rim (64). The container further comprises a handle (52) extending outward from at least one side of the container, the handle having two parallel spaced apart sideplates (54), each sideplate having a lower edge profile for defining a downwardly concave recess (62). When one container is stacked inside a like-configured second container, the upper rim of the bottom container is nested within the handle sideplate recesses of the top container, and the sidewalls of the underlying container are held in a fixed vertical orientation. Recesses (49) are further provided within sidewalls (6) of the container, adapted to receive handle projections from a like configured second container, whereby the containers can be stored in a side by side abutment.

Abstract: A connector clip for connecting waste receptacles is disclosed, comprising an elongate body 2 of substantially M-shape in cross-section, having inverted U-shaped attachment portions 4,6 extending from a central connective loop portion 8. The portions 4,6 clamp over upper rims of two receptacles, whereby placing the receptacles in a side by side optimal spacing, and the elastomeric composition of the clip provides a positive connection with the receptacles, yet enables one receptacle to be disconnected from the other if so desired. The attachment portions 4,6 and the connective portion 8 define a longitudinal channel 30 which is open at the top and opposite ends, whereby admitting the upper edge of a plastic garbage bag positioned in one or both of the receptacles.

Abstract: A container (10) includes a base portion (11) having a cover (12) attached thereto by a hinge assembly (13). Plates (25, 26) extend outwardly from the base portion (11) and together with arms (27, 28) extending outwardly from the cover (12) carry a latch mechanism (34) to maintain the cover (12) in an open position. The latch mechanism (34) includes complementary lock barbs (35, 38) on a plate (26) and an arm (28), each lock barb (35, 38) having a camming surface (36, 39) and a lock surface (37, 40). As the cover (12) is rotated, the camming surface (39) of the lock barb (38) rides over the camming surface (36) of the lock barb (35) until the lock surfaces (37, 40) engage each other.

Abstract: A dual purpose card edge connector which can accept a printed circuit card having conductive pads on one center-line spacing or another printed circuit card having conductive pads on a different center-line spacing. More particularly, contact portions on contact elements disposed in an insulating housing are alternatively located at two different levels to cooperate with positioning members in the card receiving slot so that a circuit card not having edge notches is positioned on the positioning members and the conductive pads are engaged by the contact portions at the upper level while a circuit card having edge notches slide past the positioning members and the conductive pads thereon is engaged by the contact portions at both levels.

Abstract: A connection system for electrically interconnecting circuits on a printed circuit mother board and printed circuit daughter board. More particularly, the connection system includes a first connector having a slot and for mounting on the mother board and a second connector having a blade for being received in the slot of the first connector and for being attached to an edge of the daughter board. Polarizing keyway and key bar are provided on respective first and second connectors to prevent incorrect insertion and to provide precise registration of contact elements in the respective connectors.

Abstract: The present invention relates to compliant sections utilized on contact elements which are mounted in plated-through holes in printed circuit boards, generally in conjunction with card edge and other electrical connectors. More particularly, the invention disclosed includes two elongated spring members having generally centrally located, load-receiving segments so that forces exerted against the spring members are more uniformly distributed along the lengths thereof.

Abstract: The present invention relates to zero insertion force card edge connectors with flexible film circuitry interconnecting the mother printed circuit board on which the connector is mounted and the daughter printed circuit card received in the connector. Actuation of cam means closes the connector and moves the circuit pads on the film up and down against the card circuit pads to provide wipe and back-wipe.

Abstract: The present invention relates to zero insertion force card edge connectors with flexible film providing the interconnecting medium and with improvements to cam means so as to obtain accurate alignment and keying capabilities required in such high density connectors.

Abstract: The invention disclosed herein relates to a biasing means provided in one end of a card-receiving slot of a card edge connector. The biasing means includes a spring loaded wedge slidably positioned in a sloping passage at one end of the slot. The wedge includes a vertical surface which engages a side of the card as the card is inserted in the slot. The wedge moving down the sloping passage increases the slot length to accommodate the card width without exerting significant longitudinal force against the end walls of the connector. Further, the wedge cannot be moved up the passage by an uneven force being exerted on the card; accordingly, the card can only be removed from the slot in a straight line.

Abstract: The present invention relates to a connector system for electrically connecting a circuit card to a circuit board. More particularly the connector system includes an upper card-carrying member mated into a lower board mounted member without requiring insertion forces. Cam means on the lower member move the upper member laterally to electrically engage the contact elements positioned in both members.

Abstract: The present invention relates to a terminal which may be attached to a ceramic chip or other type substrate and which may be plugged into a PCB and thereby provide electrical connections between the substrate and the conductive traces on the board. More particularly, the terminal includes a receptacle for receiving the edge of a chip for mechanical retention and electrical contact, a spring member which protects the chip from thermal and mechanical stresses, means for insertion into a board's plated-through hole, and means establishing redundant short electrical paths between the pad on the chip and the traces on the PCB. Further, the terminal may be encapsulated in an elastomeric material which provides additional spring resiliency and also provides an environmental seal.
