  • Patent number: 6851714
    Abstract: A securement arrangement for a seat belt closure of a three-point seat belt system in a vehicle comprises an anchor piece secured to the vehicle, a closure body, and a generally U-shaped closure body retaining assembly for mounting the closure body on the anchor piece. A spring disposed between a pair of U-forming legs of the closure body retaining assembly biases the closure body into its home position. A contact element emits a signal to be processed by an onboard signal processing unit when the closure body, due to the application thereto of a load imposed by the seat belt, is displaced so as to overcome the biasing force of the spring. The contact element correspondingly moves out of contact and emits a signal in response to its movement out of contact.

  • Patent number: 6852228
    Abstract: The invention relates to the purification of untreated water which is polluted with dissolved organic carbon compounds which can be biologically or adsorptively removed in a three-step process, whereby the upstream purification step is predominantly biological, i.e. operates as a biofilter (1), and both subsequent purification steps are predominantly adsorptive in nature, i.e. operate as adsorbers (2, 3). The biofilter (1) is purified by backwashing, whereby the backwashing periods occur according to the TOC determined between the biofilter (1) and the upstream adsorber (2) and/or running time and/or pressure loss. The upstream adsorber (2) is also cleaned by backwashing and is subsequently shifted into a downstream position alternating with the other adsorber (3). The method is suitable for obtaining TOC concentrations in treated water of less than 500 ppb.

  • Patent number: 6848402
    Abstract: Apparatus suitable for use in reciprocally opening and closing a camshaft-actuated valve may include a rotating camshaft (20) having first and second cams (16, 17, 18) respectively defining first and second amounts of valve opening distance. A cam follower (10, 11, 12) may be defined on a mounting pin (24) so as to operatively engage the first and second cams in an alternating manner. At a first rotational position of the cam follower relative to the camshaft, the cam follower operatively engages the first cam and generates the first amount of valve opening distance. At a second rotational position, the cam follower operatively engages the second cam and generates the second amount of valve opening distance. A valve lever (6) transmits the respective generated first and second amounts of valve opening distance to the valve. A locking device (50) releasably locks the mounting pin and cam follower in the respective first and second rotational positions.

  • Patent number: 6848398
    Abstract: A two-cycle engine is provided and has a cylinder with a combustion chamber delimited by a reciprocating piston. The engine has an inlet for fuel/air mixture, an outlet out of the combustion chamber for exhaust gas, and four transfer channels that open into the cylinder via inlet windows, and fluidically connect the crankcase with the combustion chamber as a function of the piston position. The transfer channels have a connecting portion to the crankcase, an ascending portion substantially parallel to the longitudinal axis of the cylinder, and an opening-out portion into the combustion chamber. The planes defined by that side wall of the transfer channel close to the outlet that is remote from the outlet, and by the side wall of the transfer channel remote from the outlet that is close to the outlet, intersect in a line extending on the side of the mirror plane facing the transfer channels.

  • Patent number: 6847012
    Abstract: The invention relates to a device for measuring the temperature of substrates, notably semiconductor wafers. The device comprises at least one radiation sensor for measuring the radiation emitted by the substrate and an element (19) which restricts the field of vision of the radiation sensor and is positioned between the substrate and the radiation sensor. The substrate temperature can be determined correctly and simply, even if the substrate vibrates or is tilting, owing to the fact that the edges (20) of the element extend in a straight line. The invention also relates to a corresponding method.

  • Patent number: 6843639
    Abstract: A blower having a discharge tube, which can be secured to a housing, for guiding a stream of air is provided. The air stream flows in a main stream direction in the discharge tube and in a discharge stream direction out of the discharge tube. The discharge stream direction forms an angle of greater than 0° with the main stream direction. The discharge stream direction has a transverse component that extends perpendicular to the main stream direction, which produces a force in the discharge tube perpendicular to the main stream direction. To reduce the transverse force produced in the discharge tube, a partial air stream is branched off out of the discharge tube and flows in a partial stream direction that has a compensation component that is directed opposite to the transverse component.

  • Patent number: 6842979
    Abstract: A method is provided for producing a cylinder in a two-cycle engine. The cylinder bore is first machined as a preparation for the provision of a coating. The thereby resulting window edges that surround an inlet window are then at least partially chamfered. The cylinder bore is consequently provided with the coating, which at least partially overlaps the chamfered window edge. There thereby results in the region of the window edge a location of least spacing relative to the axis of the transfer channel. The piston liner or gliding surface is finally machined to a finished dimension such that in the region of the chamfered and coated window edge or corner there is formed a coating edge having a wall spacing relative to the location of least spacing, which such wall spacing having a maximum value of 0.7 mm.
