  • Patent number: 6572008
    Abstract: Fastening an attaching eye to the base of a dashpot by welding. The object is to simplify tooling and position the parts more accurately. The eye (3) is fabricated from strip, preferably by rolling or bending, prior to welding and is provided with an outward-tapering V-shaped abutment (4). The base (1) is provided with a transverse W-shaped groove comprising two rounded depressions (5 & 6), their depths and middle elevations (7) dimensioned to ensure that the eye will come into contact with the lateral edges (8 & 9) of the groove. The abutment is more or less in alignment with the groove's elevation.

  • Patent number: 6561326
    Abstract: A device for attenuating the amplitudes of impacts, especially against the wheel of a vehicle. At least one piston is accommodated in a housing and divides it into two attenuating spaces. The piston is attached to a piston rod and operates in conjunction with a component that handles smaller amplitudes. This component is either a diaphragm or a displaceable rigid disk that divides a space and communicates hydraulically with either the upper or with the lower attenuating space.

  • Patent number: 6547503
    Abstract: A method for manufacturing a pressurized two-chambered container in the form of an aerosol can, in which a housing is provided with an opening that can be sealed tightly by a spray or aerosol valve. A product chamber and a propellant chamber are formed separately fluid-tight from each other by a flexible diaphragm in the housing. The product chamber can be charged with a product which can be release through said valve. The propellant chamber can be charged, on the other hand, with a compressed propellant. The product chamber communicates with the product-release opening. At least one end of a blank is left open to constitute subsequently the housing. The diaphragm is inserted into the blank through the open end, and the blank then is formed into the housing. An edge of the open end of the blank is reformed to narrow it into an integral mouthpiece that accommodates the product-release opening.

  • Patent number: 6546690
    Abstract: An especially stable glass module (3) that is resistant to bending stress and releases no shards when shattered. The module can be employed to construct an area of a wall, roof, or ceiling entirely of glass and without frames or fittings of metal or another material. The module (3) consists at least two components (31 and 35) fastened total surface to total surface by cement or laminating adhesive. At least one component is a length of glass L or U structural section. The lengths are preferably of clear or ornamental glass, rolled glass, or reinforced glass, wire-reinforced glass or single-pane safety glass for instance. A wall, roof, or ceiling area composed of such modules will not need auxiliary support and will comply with strict specifications for the safety of anyone under it.

  • Patent number: 6520298
    Abstract: A railroad track brake in which a piston track brake is shifted out of an active state into an inactive state by a track-brake lowering device with a length of structural section extending along the piston track brake and having drag bars attached thereto while engaging the piston track brake. The active and inactive states are produced without contacting the housing of the piston track brake, and the braking process is free of acceleration forces. The drag bars contact the piston track brake only when it is in an inactive state to prevent acceleration forces.

  • Patent number: 6460663
    Abstract: A hydraulic vibration damper for motor vehicles comprising a cylinder (1) containing damping fluid and a sealed, axially displaceable piston rod (2) that plunges into said cylinder. A damping piston (3) is secured to the lower end of the piston rod and divides the cylinder area into two working areas (4, 5). Said damping piston is provided with passages that can be modified and which are controlled by throttle valve bodies, in addition to a bypass for the pressure and traction stage, whereby the cross-section of the bypass is adjusted by an electrovalve that functions in three or more stages and the toroid coil more or less opens a valve slide (13), whereupon two or more bypass openings are released in a successive manner. The inventive damper is designed in such a way disruptive influences caused by constantly changing hydraulic forces arising from the flow of the damping agent are reduced when the flow from the bypass channels is shifted or controlled.

  • Patent number: 6450084
    Abstract: A piston (1) with a piston ring (10) for a hydraulic or pneumatic unit fitted with a damping device and is mounted on a piston rod, dividing a cylinder (9) into two working areas and consisting of at least two parts (2, 9) that are adjacent to a surface (4) extending perpendicularly to the axis of symmetry (5). The piston ring (10) has an axial extension (14) that is several times greater than the thickness (15) of the wall of the ring and is disposed in an outer circumferential groove (6) that extends over both parts (2, 3). The invention provides a piston that prevents rumbles and is easy to produce, requiring only a few components.

  • Patent number: 6436322
    Abstract: The invention relates to a method for recycling polyethylene terephtalate (PET) flakes, characterized in that the flakes are extruded and granulated under vacuum, after which the granulate is aftercondensed in a solid phase under vacuum. Extrusion is preferably carried out in differentiated vent zones and aftercondensation of the solid phase is dependent on temperature, vacuum and time spent in a tumble dryer. Said dryer ensures the even and careful mixing and constant viscosity of the PET product. Said method is used in particular for making PET beverage bottles.

  • Patent number: 6422112
    Abstract: A machine for cutting stacked sheets of stock. The machine has a counter for accommodating the stock. The rear of the counter accommodates the stock to be cut and the front of the counter the cut stock. The rear of the counter also accommodates a mechanism for advancing the stack and a baffle for one side of the stack to rest against. A bent is positioned above the counter and accommodates a blade for cutting the stock and a holdfast that can be lowered onto the top of the stack. A control panel and a display panel are positioned on the front side. The machine in accordance with the present invention is characterized by at least one camera (22) at the rear (9) of the counter. The camera monitors the position of the stock in relation to the stack-advancing mechanism (10) or the lateral baffle (12) and displays on the display panel (17) a real-time image (26) of what it can discern.

  • Patent number: 6379639
    Abstract: A method for purifyiing flue gas derived form incinerators burning refuse, wood, or sludge, in which the flue gas is cooled in a spray drier. A dust remover removes the dust from the flue gas. The flue gas is filtered through a filter-bed adsorber having filtering surfaces and packed with an adsorbent containing calcium hydroxide. The filter-bed adsorber is cleaned at intervals for removing adsorbate from the filtering surfaces. An aqueous suspension is prepared from at least some of the adsorbate that is removed from the filtering surfaces, and the flue gas is brought into contact with the suspension in at least one location upstream of the filter-bed adsorber for further separation of contaminates. The aqueous suspension is supplied to the spray drier for improving the purification of the flue gas.

  • Patent number: 6374745
    Abstract: The invention relates to a line-changing device for the tracks (1, 2) of a magnetic levitation train. The tracks (1, 2) are formed by track supports arranged one after the other and the lines are changed by means of a rail joint between the tracks (1, 2). To connect the tracks a track support configured as a bendable support (5) is positioned along each track which bendable support can be bent to establish a connection between the tracks (1, 2). In its bent state each bendable support can be positioned in relation to the other bendable support (5). Along each track (1, 2) a track support situated next to the bendable support (5) is configured as a connecting support (6), which when the rail joint is established can be moved out of the clearance gauge of the train. The invention consists in the fact that the connecting supports (6) can be moved without deformation.
