摘要:
A pump fitting has an inlet adaptor (10) for connection to an outlet (39) of a container (38) of fluid and including an inlet passage (10), an outlet passage (11) for fluid and a pump housing (12) between the inlet passage (10) and the outlet passage (11). The pump housing (12) contains a rotor (17) rotatably received in an interior surface of the housing (12). The rotor (17) includes a housing-engaging surface (23, 24) co-operating with the interior surface of the housing (12) to form a seal therebetween and also including at least one shaped surface (21, 22) radially inwardly of the housing-engaging surface and forming with the interior surface of the housing a chamber (25, 26) for conveying fluid from the inlet passage (10) to the outlet passage (11) on rotation of the rotor (17). A seal (28) is provided between the outlet passage (10) and the inlet passage (11), the seal (28) being urged into engagement with the rotor (17) to prevent fluid passing from the outlet passage (11) to the inlet passage (10) as the shaped surface rotates. The inlet passage (10), the outlet passage (11) and the housing (12) are formed as a one-piece molding.

An aircrew ensemble comprising a garment (20, 21) for covering at least a part of a body of a wearer and an inflatable counter-pressure bladder (33, 41), carried by the garment (20, 21). The inflatable counter-pressure bladder (33, 41) is formed from a moisture permeable material allowing the passage therethrough of perspiration from the wearer's body.

In one example, a basketball system includes a backboard (300) to which a goal (400) is configured to be attached, a support structure (200), a connecting structure configured to connect the backboard to the support structure (500), a lockable height adjustment mechanism (600) operably disposed with respect to the backboard, and a means for absorbing shock (700). When the height adjustment mechanism (600) is locked, the means for absorbing shock (700) enables temporary displacement of the backboard (300) in response to imposition of a load or force on the backboard (300) if the imposed load or force exceeds a threshold load or force, respectively.

Transmission systems, assemblies, and components are described. In particular, aspects of the present disclosure relate to an infinitely variable transmission that maintains constant tooth engagement during changes in gear ratio. In one aspect, a transmission includes an axially movable sheave coupled to a chain. The sheave rotates around a drive axis. At least partially within the sheave is a set of moon gears. The moon gears orbit around the drive axis and are rotatable around respective internal axis. As the sheave moves axially, the chain and the set of moon gears move radially to define different gear ratios, with the gear ratios being changeable in infinitely small increments. A synchronization system moves the set of moon gears radially to correspond to the axial position of the sheave. A correction system optionally controls rotation of the moon gears to rotate teeth of the moon gears into alignment with the chain.

An attachment system principally use on garment (10, 30) provides a number of aligned loops (15) on the garment and a number of aligned loops (24) on a load such as an equipment pack (17). The load also includes an elongate securing member that extends from the load with a flexible proximal portion (26) and a stiffened distal portion (27). The stiffened distal portion (27) can be very readily threaded through successive ensemble loops (15) and load loops (24) to pull the flexible proximal portion (26) through the loops (15, 24) to attach the load (17) to the garment (10, 30). The stiffened distal portion (27) is then fed back through the loops (15, 24) to provide a geometric lock that prevents the load (17, 18) detaching from the garment (10, 30). Various loads can be attached in this way.
摘要:
Methods and apparatus are provided for detection of large leaks in sealed articles. Apparatus for leak detection includes a first sealable chamber configured to receive a test piece containing a trace gas, a second sealable chamber, a first valve coupled between the first and second chambers, a leak detector having a test port, a trace gas permeable member coupled between the second chamber and the test port of the leak detector, a vacuum pump having an inlet, and a second valve coupled between the second chamber and the inlet of the vacuum pump. The permeable member may be quartz, which is permeable to helium when heated. The leak detector may be an ion pump or a helium mass spectrometer leak detector.
摘要:
Even in the case of a bar-like small terminal connection, its strength is retained. In (a), a strip (21) made, for example, of a thin metal sheet having a thickness of 0.2 mm and a predetermined width is collapsed by rolling to a thickness of 0.16 mm as in (b). Subsequently, as in (c), the longitudinal opposite sides (22, 23) of the strip (21) are erected with respect to the base plate (24), then inwardly bent, as in (d), and folded onto the base (24), as in (e). Further, the folded opposite sides (22, 23) are erected together with the base plate (24) into a closely contacted state, whereupon as in (f), the folded body is mechanically compressed from all sides into a form having a 0.64-mm square cross section.
摘要:
A lock has a body (10) holding a locking member (11) that can be locked to or released from the body (10) by, for example, operation of a key (21). The lock includes an alarm (25) that is triggered by the locking of the locking member (11). If, however, the lock is unlocked and relocked within a predetermined time interval, the alarm (25) is disarmed. In this way, the lock can remain locked but with the alarm (25) disarmed. The signals that cause the alarm (25) to arm and disarm can be produced in any convenient way.

A system and method for selling advertising may include operating an electronic display network operating in a retail store. The network may include electronic displays interspersed among product displays and arranged to present a shopper with each advertisement among multiple repeating advertisements a predicted number of multiple times as a function of shopper metrics and a configuration of the electronic display network during a shopping trip in the retail store. Airtime may be sold to an advertiser for an advertisement to be displayed on the electronic display network.
