  • Patent number: 6279583
    Abstract: A mascara brush is disclosed that has a twisted wire core supporting a plurality of regularly disposed radially extending short and long bristles. The tips of the long bristles define an outer envelope of the brush. The short and long bristles are interspersed such that tips of the short bristles form a layer spaced inwardly from the outer envelope. The brush can be made without regard to bristle stiffness. Because the brush can be made without regard to bristle stiffness, the short bristles can have a degree of flexibility for a given length that is equal to or greater than a degree of flexibility for a given length of the long bristles. The brush is made by first forming a brush blank. The brush blank is made by providing a plurality of bristles of substantially equal length between a pair of parallel wire segments. The wire segments are initially twisted sufficiently to secure the bristles for subsequent steps.

  • Patent number: 6279594
    Abstract: An upright cylindrical valve body has an inlet port axially aligned with an outlet port. A valve member is retained for reciprocal movement into and out of engagement with a valve seat axial aligned with fluid flow between the inlet and outlet ports. A relief port positioned adjacent to the outlet port exhausts fluid that remains in the valve above the valve seat after it is closed. The valve member is normally maintained in a closed position. Fluid flow into the inlet port actuates the valve. A portion of the fluid flowing through the valve chamber is diverted through passageways by a pair of remote controlled solenoid valves to open the valve. When it is desired to close the valve, the solenoid valves are actuated to evacuate fluid internally within the valve so that the valve member is returned to a closed position. A relief valve in the outlet port exhausts fluid from the upper end of the valve when the fluid pressure falls below a preselected magnitude.

  • Patent number: 6279595
    Abstract: The present invention provides an axially-rotated valve which permits increased flow rates and lower pressure drop (characterized by a lower loss coefficient) by using an axial eccentric split venturi with two portions where at least one portion is rotatable with respect to the other portion. The axially-rotated valve typically may be designed to avoid flow separation and/or cavitation at full flow under a variety of conditions. Similarly, the valve is designed, in some embodiments, to produce streamlined flow within the valve. A typical cross section of the eccentric split venturi may be nonaxisymmetric such as a semicircular cross section which may assist in both throttling capabilities and in maximum flow capacity using the design of the present invention. Such a design can include applications for freeze resistant axially-rotated valves and may be fully-opened and fully-closed in one-half of a complete rotation.

  • Patent number: 6279597
    Abstract: Inside the casing (1), there are three or more ribs (8) arranged with their longitudinal axes parallel to the closing body's direction of movement when closing so that each rib forms a slide-way for the closing body (5) moving from open into closed position. Into each of these ribs there is cut a first groove (10) in which is placed a shaped part (11) that supports the closing spring (9). At least the ribs arranged approximately opposite to the tappet (20) have a second groove whose side facing the seat (7) forms a rest edge (18) on which the control edge may rest when the closing body is in open position. When the fusible soft solder component (21) is melting away, the tappet changes its position in axial direction under the force exercised by the closing spring. Due to this change of position, the control edge is no longer resting on the rest edge, and the closing body driven by the dosing spring switches over into its close position.

  • Patent number: 6279617
    Abstract: An account has been given for corrosion-protection of metal constructions, e.g. in the form of a pipeline consisting of interconnected pipelines (10, 10a, 10b, 10c, 10d) and, possibly, incorporatable in a larger pipe system. Said metal construction is, for purpose of corrosion-protection, assigned one or more sacrificial anodes in the form of one or more bodies made of a metal or a metal alloy which is less noble than the metal to be corrosion-protected. In order to utilize the sacrificial anode(s) beyond its corrosion-protecting ability within said construction, said one or more sacrificial anode bodies are included in the metal construction as at least one functional part thereof, e.g. in the form of at least one pipe length (10).

  • Patent number: 6279619
    Abstract: When preliminarily storing yarn on a drum-shaped storage body of a feeding device in which the yarn is placed on the storage body by an electrical winding drive with relative rotational movements between a winding element and the storage body, with running periods and resting periods, during each resting period a holding torque is generated in the winding direction. The holding torque is generated electrically in the winding drive mechanism. A backturn detent device serves to block a reverse rotation of the winding element during resting periods. The backturn detent device is actuated by a holding current during each resting period.

  • Patent number: 6279622
    Abstract: A system and a method for delivering and metering a fixed volume of liquid, such as a liquid sterilant from a container into a vaporization system. The method for the delivering system includes the steps of sensing a requirement for additional liquid sterilant, determining whether the liquid sterilant to be added is acceptable for use, and delivering the liquid sterilant from a container into an accumulator. The method of metering the liquid sterilant into the vaporization system includes creating a vacuum in a chamber connected to the vaporizer and delivering the liquid sterilant into a vaporizer while continually sensing the flow of the delivery. The metering system maintains a slow, controlled flow in order to achieve efficient vaporization of the liquid sterilant and to provide accurate sensing of the gas/liquid interface.

  • Patent number: 6279624
    Abstract: Automatic refuelling of vehicles, primarily cars, is effected by a fuelling robot. An optical sensor is disposed adjacent the fuelling robot and is adapted to detect optically the position of the fuel-tank flap of a vehicle parked for fuelling purposes, relative to the rest position of the robot head. The sensor is also adapted to detect the position of the orifice of the fuel-tank filler pipe relative to the position of the robot head. A computer receives position signals from the sensor and guides a robot-carried opening device into abutment with the fuel-tank flap to open the flap, and to effect docking of a fuelling nozzle within the fuel-tank filler pipe orifice.

  • Patent number: 6279629
    Abstract: The subject basic method and its modifications are used to provide logs reconstituted from smaller diameter trees up to 12 inches diameter at their bases. The basic method is practiced using the following steps: 1. Cutting felled trees at cutting points into a plurality of segments which, naturally, are tapered, each segment having a length, a larger diameter end and a smaller diameter end, the length being in a range of random lengths such that the larger end diameter is in a range of 0.2 to 2.0 inches larger than the smaller end diameter, with 0.2 inch preferred; 2. selecting from the plurality of segments cut from one or more trees, a plurality of groups of segments which have smaller end diameters no more than ½ inch different; 3. joining segments from each group end-to-end to form reconstituted logs of optimum lengths for processing into wooden structural units. In one modification of the basic method, flawed portions are removed from the logs prior to cutting them into segments.
