Abstract: An electronic card enclosure includes a frame (1), a first shell half (2), a second shell half (3) and a shield cover (4). The frame (1) is integrally formed as a rectangular member having a rear border (14), two side arms (12) and a front border (11). The shell half (2, 3) and the shield cover (4) are rectangular-shaped. In assembly, a pair of second rim edges (33) of the second shell half (3) secures a pair of first rim edges (22) of the first shell half (2) through accommodating the two side arms (12) of the frame (1) therewithin.

Abstract: An electrical connector (2) includes an insulative housing (20), a number of electrical terminals (21), a conductive shield (23) and a retention element (22). The insulative housing includes a base portion (24) defining a receiving cavity (200) and an island portion (25) extending through the receiving cavity to substantially divide the receiving cavity into a first portion (201) and a second portion (202). The retention element includes a retention portion (223) retained by the insulative housing, a transition portion (222) extending forwardly from the retention portion and a curved portion (221) extending upwardly and rearwardly from the transition portion to project into the second portion of the receiving cavity.

Abstract: An electrical connector (100) mountable on a bottom side of a PCB (200) includes a dielectric housing (40), a plurality of terminals (50) retained in the housing, and a shielding case (130) covering the housing. The shielding case has a front section (20) with an upwardly protruding orientation key (210), a rear section (30) and a covering section (10). The covering section is formed from one piece of metal sheet and provides a pair of side walls (12), a transverse wall (11) interconnected therebetween, two metal feet (120) projecting upwardly from corresponding side walls for securing the connector to the PCB and a detent lock (110) formed in a middle of the transverse wall bending inwardly and rearwardly for providing a retention force against a mating complementary connector.

Abstract: A pressure flushing system for use in a toilet tank includes a housing with a water inlet conduit, an air and water inlet assembly connected to the conduit and to the housing, and a water outlet for the housing. There is a flush valve within the housing for controlling flow of water from the inlet to the housing outlet. The air and water inlet assembly includes a chamber, with a water inlet connected to the chamber, and an outlet connected to the chamber. There is an air inlet accessible to air at atmospheric pressure and a passage between the air inlet and the chamber. A check valve is located in the passage, with the check valve opening in response to a venturi effect caused by water flow through the chamber to draw air into the chamber to mix with water flowing through the chamber and to the outlet. The check valve includes an elastomeric sleeve positioned within the passage and having normally closed flexible lips extending toward the chamber.

Abstract: A pressure flushing system for use within a toilet tank includes a pressure tank which has a predetermined volume. There is a water outlet for the tank, a water inlet for the tank, and an air inlet for the tank. The air inlet is associated with the water inlet whereby water flowing into the tank draws air into the tank. A portion of the tank is thus occupied by water and a portion is occupied by air, with the air applying pressure to the water. There is a valve within the tank which controls the flow of water from the tank through the outlet. The volume of water within the tank which may flow through the outlet at any one operation of the valve is limited by a dam which is located within the tank and surrounds the outlet.

Abstract: A pressure flush tank for toilets is formed and adapted to be located within a toilet enclosure and is preferably formed of a non-metallic material such as plastic. The pressure flush tank has an essentially rectangular vertical cross section and an essentially rectangular horizontal cross section, with the tank including an upper housing portion and a lower housing portion. There is a peripheral projection on the lower surface of the upper housing portion and a peripheral recess along a facing surface of the lower housing portion, with the projection being positioned within and ultrasonically welded to the recess. Each of the housing portions has side walls and end walls, with each housing portion having reinforcing interior walls extending between opposing side walls to provide strength and rigidity for the pressure flush tank.

Abstract: A pressure flush system for use within a toilet tank includes a pressure flush tank which has an air inlet and a water inlet. Water is maintained with the pressure flush tank under air pressure. There is a water discharge for said tank to direct water to a toilet bowl. The tank contains a flushing valve system, which, when operated, will direct water under air pressure through said water discharge opening. The water discharge includes a housing which is attached to the bottom of the pressure flush tank and there is a one way check valve in the water discharge housing and located outside of the pressure flush tank. The one way check valve prevents water passing therethrough when the pressure flush tank is discharged and it permits the draining of water outside of the pressure flush tank and within the toilet tank through the water discharge opening.
