摘要:
An apparatus (10) helps protect an occupant (20) of a vehicle (12). The apparatus (10) includes an inflatable vehicle occupant protection device (14) that includes panel (100) of material that helps define an inflatable volume (54) of the protection device. A vent opening (104) vents inflation fluid from the inflatable volume (54). A pleat (120) is folded in the panel (100). The pleat (120) is positioned against a vehicle surface (62) while the protection device (14) is in a normally deployed condition to help block inflation fluid from venting through the vent opening (104).
摘要:
A method and article for packaging an automatic external defibrillator for use without a prescription are described. The OTC AED is encased in a rigid polymeric disclosure which is a distinctive color or set of colors to enable the OTC AED to be readily distinguished in the home environment. The defibrillator is packaged in a box with multicolored depictions of the defibrillator on multiple sides of the box, which enable the distinctive coloring of the defibrillator to be readily identified by the exterior of the packaging.
摘要:
A vehicle occupant protection apparatus (10d) includes an inflatable occupant protection device (300) and a support member (316). A vent opening (350) extends through the support member (316). A vent member (360) is associated with the vent opening (350). The vent member (360) initially closes the vent opening (350). Inflation fluid moves the vent member (360) relative to the support member (316) for enabling a flow of inflation fluid through the vent opening (350). A tether (386) extends between the inflatable occupant protection device (300) and the vent member (360). The tether (386) is responsive to inflation of the inflatable occupant protection device (300) away from the support member (316) by more than a predetermined distance for moving the vent member (360) relative to the support member (316) for reducing the flow of inflation fluid through the vent opening (350).
摘要:
An air bag (12) includes at least one tether (44) and an inflation fluid source (14) having two modes of operation. In the first mode of operation, the inflation fluid source (14) is activated to provide a first inflation fluid pressure in the air bag (12). In the second mode of operation, the inflation fluid source (14) is activated to provide a second inflation fluid pressure in the air bag (12) higher than the first pressure. The tether (44), which helps to control the shape of the air bag (12), tears in response to the second inflation fluid pressure in the air bag.
摘要:
A vehicle occupant protection apparatus (10) includes an inflatable occupant protection device (12) and a support member (40) having a vent opening (50) through which inflation fluid may flow. The apparatus (10) also includes a mechanism (58) for controlling a flow of inflation fluid through the vent opening (50). Inflation fluid pressure within the inflatable occupant protection device (12) tends to move the mechanism (58) for increasing a flow of inflation fluid through the vent opening (50). The mechanism (58) is responsive to inflation of the inflatable occupant protection device (12) beyond a predetermined distance for restricting the flow of inflation fluid through the vent opening (50). The apparatus (10) further includes a locking member (96) for blocking the mechanism (58) from increasing the flow of inflation fluid through the vent opening (50) after the inflatable occupant protection device (12) has inflated beyond the predetermined distance.

摘要:
A method and an arrangement for preheating the fuel for a firing plant which is operated with liquid or gaseous fuel, which is fed to the firing plant via a feed line, having at least one heat-exchanger unit which is thermally coupled to the feed line and through which heat is transferred from a heating medium, which is directed in a heating circuit, to the fuel.The invention is distinguished by the fact that the pressure at which the fuel is directed in the feed line is greater than the pressure at which the heating medium is directed in the heating circuit, at least in the region of the heat exchanger.
摘要:
A temperature responsive electric overcurrent protection module incorporated in an electric circuit on a circuitboard has a PTC resistor which heats up when subjected to an excessive current. Its resistance rises with its temperature to control the current and protect the circuit, including electric components thereof. To protect the circuit against occasionally encountered, large overcurrents, which could damage the circuits and/or cause a burn-out, a thermal switch or overcurrent fuse is provided which comprises an electrically and thermally conductive contact plate, and an associate thermal switch formed by a planar frame secured to the substrate and a spring arm protruding therefrom. The contact plate is spaced from the substrate, and a free end of the spring arm is secured to the contact plate with a heat responsive solder, thereby prestressing the spring arm so that, upon a melting of the solder due to an overheating of the contact plate by the PTC resistor, the spring arm automatically moves away from the contact plate, thereby opening the circuit and preventing damage to it from the excessive overcurrent.
摘要:
The invention relates to a process for the compression of molding sand in casting molds having a pattern plate with a pattern arranged therein. The molding sand is introduced loosely into the molding space located above the pattern plate and is thereafter fluidized to a final pressure of 20 bar maximum by means of a compressed-air surge acting on the molding sand followed by compression, by mechanical pressing. The process of the present invention provides a smooth pressure surge which is subdivided into at least a two part gradient in its pressure-rise time curve, so that the first part of the pressure-rise gradient takes place from 0.3 to 18 bar/sec to a pressure P.sub.1 and the second part has an increased pressure-rise gradient which takes place from 18 to 95 bar/sec. to a pressure P.sub.2 where P.sub.1
