  • Publication number: 20060082012
    Abstract: A bonded web of multi-component strands that include a first polymeric component and a second polymeric component is capable of overcoming a number of problems associated with nonwoven webs including both stickiness and blocking. The first polymeric component and second polymeric component are arranged in substantially distinct zones extending longitudinally along at least a portion of a length of the strands which make up the web with the second component containing a zone constituting at least a portion of the peripheral surface of the strand. The first polymeric component also has an elasticity which is greater than that of the second polymer component. A process producing elastomeric spunbonded nonwoven fabrics which utilizes the activation by incremental stretching of the strands is also provided.

  • Publication number: 20040071567
    Abstract: An air compressor unit having an enclosure with a base. A motor is rigidly mounted to the base, and the motor drives both an airend and an impeller. The airend is pivotally mounted with respect to the base. The airend is directly connected to a horizontal separator tank, and the separator tank supports the airend. The airend and separator tank comprise a single integrated unit, and the separator tank is pivotally mounted to the base. The motor is a dual shafted motor having a drive side shaft and a non-drive shaft extending from opposite ends of the motor. A drive system is coupled to the drive side shaft and transfers power from the motor to the airend. The drive system is a belt and pulley system, and the airend is pivoted with respect to the motor to adjust belt tension. The impeller is coupled to the non-drive side shaft.

  • Patent number: 5031080
    Abstract: A portable incandescent light assembly having a selectably interposable filter is disclosed. The light assembly is particularly applicable to night vision situations for airplane pilots. The light assembly comprises a housing in which a light source and a filter for filtering out infra-red light are located. The light assembly further comprises a mechanism for rotating the filter within the housing between a filtering position in which the filter is disposed across a light output axis and a non-filtering position in which the filter is disposed parallel to the light output axis.
