  • Patent number: 6766971
    Abstract: A method and an installation for operating a system for comminuting scrap material is provided. The installation includes a supply device (1) for the scrap material to be comminuted, and a comminuting machine (2) with at least one motor-driven (2.3) rotor (2.2) which has comminuting tools (2.2.1) and is horizontally positioned in a housing (2.1) and has an ejection door (2.1.1). The inventive installation also includes drive means for controlling the power and for protecting the installation from scrap material which is difficult to comminute or which cannot be comminuted at all, such as coarse, heavy or hard parts. For optimizing the comminuting process, the values of the motor output, of the rotation speed of the rotor, of the temperature of the motor and the motor bearings and/or of the height of the scrap material flow (3) supplied to the comminuting machine (2), are inputted in a controller (4) and used to control/regulate the scrap material supply. Technical means (4.5, 4.6, 4.

  • Patent number: 6660998
    Abstract: The invention relates to a timing device for positioning a machine part which is moved by an actuator and a control circuit in a straight or circular path inside a housing. A timing disk or a timing ruler is used as a reference point for the positioning, wherein the timing disk or timing ruler is arranged in a beam path of a light source-sensor unit. A beam mask made of a film material is disposed between a light source and the timing disk or the timing ruler. Spacer elements which face the timing disk or timing ruler, and a positioning and mounting plane for registration with a base plate are provided. Also provided are guide means for the positioning the beam mask inside the housing in front of the light source.

  • Patent number: 6484353
    Abstract: A riding type sweeper with a rear-mounted engine and a driven sweeper roller located between the front axle and the rear axle, wherein the sweeper roller transports the dirt into a coarse dirt container disposed behind the sweeper roller, from which the fine dirt is suctioned off by a filter blower unit. The filter blower unit is arranged in the region before the rear-mounted engine in a vertically superpositioned arrangement, with the blower turbine together with the fine filter being arranged in a common box.

  • Patent number: 5713078
    Abstract: This invention provides an ear protector to prevent water from entering the ear during watersport activities like swimming, surface snorkeling or child's play in the water. It provides for waterproof ear pieces which are adhered to a head band worn either over the head and under the chin or, in combination with a viewing piece, around the front of the head to the rear of the head. While the ear pieces and viewing piece are watertight around the ears or eyes due to suction of suitable material, the band can also be tightened to further promote tightness against water.

  • Patent number: 5363681
    Abstract: The invention relates to a wire shaping device. State of the art: DE 39 15 784 C1 discloses a wire shaping device comprising a program controlled rotating and displacing head which carries shaping tools and on to which moves the wire arriving from a stationary wire intake device. DE 22 64 589 C3 discloses, in the context of a spiral spring winding machine, a device for simultaneously taking in and twisting the incoming wire for producing an initial tension in the spring body. One disadvantage of the known wire shaping device is the relatively limited shapes of wire which can be produced. It is an object of this invention to improve the known wire shaping device for the purpose of increasing the range of finished shapes of the wire structures.

  • Patent number: 5136461
    Abstract: An apparatus for sterilizing and deodorizing rooms comprises a circuit part and an ionization part. High voltage of up to 3 kV necessary for forming corona discharges is produced in the circuit part. The ionization part comprises electrodes, which are arranged on both sides of an insulator plate. An electron emission is produced on the second in operation, which leads to negative oxygen ions, which destroy bacteria and spores and remove odors from the air.
