A multiple-chamber inflator (10) for a vehicle occupant protection system. The inflator (10) includes a housing (12) having a first end and a second end, and a divider disc (18) positioned in an interior of the housing (12) intermediate the housing ends to form a first (primary) propellant chamber (20) and a second (secondary) propellant chamber (22) within the interior of the housing (12). The divider (18) has a first surface (59) in communication with the first propellant chamber (20), a second surface (57) in communication with the second propellant chamber (22), and at least one aperture (60) extending between the first and second surfaces to provide fluid communication between the first propellant chamber (20) and the second propellant chamber (22). A pressure-resistant shim (62) fabricated from a low-melting point material is fixed on the divider first surface (59) over the at least one aperture (60) to block the aperture. The shim (62) is configured to melt upon exposure to a predetermined temperature generated by combustion of the propellant (48) in the first propellant chamber (20), thereby opening the at least one aperture (60). The shim (62) isolates the first chamber (20) from the second chamber (22). The shim (62) also facilitates an increase in pressure in the first chamber (20) during combustion of the first gas generating propellant (48), thereby increasing the efficiency of the combustion reaction in the first chamber (20).

The invention discloses a temperature control precision improving device of a forging mechanical press. The device comprises a crankshaft bearing bush and eccentric body bush temperature control device, and further comprises a sliding block guide rail temperature control device and a ball head temperature control device; the sliding block guide rail temperature control device comprises temperaturecontrol channels arranged at the front left side, the front right side, the rear left side and the rear right side of a sliding block, the temperature control channels are arranged at the position, provided with a guide rail plate, in the sliding block, and each temperature control channel is provided with an air inlet and an air outlet; and the ball head temperature control device comprises a wear-resistant copper pad arranged in a ball head seat, a ball head screw rod doses relative movement in the wear-resistant copper pad, the wear-resistant copper pad is connected with the ball head seatthrough a screw, a seal ring is arranged between the wear-resistant copper pad and the ball head seat, and a spiral temperature control channel is arranged on the fitting surface of the ball head seat and the interior of wear-resistant copper pad. According to the device, the temperature of the guide rail plate is controlled to be stable, the guide rail plate can not be expanded due to heating temperature rise, the precision of a sliding block guide rail is kept stable, the stability of the ball head screw rod and the ball head seat is guaranteed, and the overall precision, production efficiency and machined product quality of the forging mechanical press are improved.

The invention discloses a wireless network deployment method and a wireless access point, and the method comprises the steps of using one wireless access point (AP) and more than one wireless controller (AC) for respectively establishing tunnel connection, leading the AP to independently download and maintain a set of AP configuration for each tunnel, constructing the corresponding basic service setting (BSS) for each tunnel, providing wireless network services through the BSS, determining a forwarding tunnel according to an ID of the BSS of a wireless terminal when the AP receives uplink data of the wireless terminal and sending the forwarding tunnel determined through the uplink data to the corresponding AC. The method and the wireless access point lead one AP to be capable of establishing the connection with a plurality of AC, thereby avoiding the network performance degradation due to that a plurality of operators repeatedly deploy the AP in the same region.
