Abstract: A cleaning sleeve for use in cleaning the surfaces of industrial machinery and equipment or the like can include an abrasive pad and a fabric piece partially secured to the abrasive pad to delineate a sleeve-like structure that an operator can insert their hand into. To enable opening of the cleaning sleeve, the fabric piece can be secured along a first major side and along an opposite, second major side of the abrasive pad so that the central portion of the fabric piece is displaceable with respect to the pad. The fabric piece can have a stretchable or elastically resilient characteristic to compressively conform about the back of the operator's hand and press the operator's palm again the abrasive pad thereby retaining the cleaning sleeve to the operator.

Abstract: A tool and method for aligning multiple shaft segments which are coupled together to form a single rotating shaft. The device comprises a cylindrical bar having an annular, axially-extending outer surface, rotating means on a first end of the bar, and engaging/disengaging means fixed on the second end of the bar. The bar is temporarily inserted through a bolt hole in the collar of the first shaft and partially through an aligned hole in an adjacent coupling of the second shaft until at least a portion of the engaging/disengaging means is positioned within the bolt hole of the second collar. The engaging/disengaging means engages the second collar so that a turning force from the first shaft is transmitted to the second shaft. The engaging/disengaging means also disengages from the second collar by rotating the bar after rotation of the shaft is ceased.

Abstract: A dual-purpose powered rotating infant pacification device and method comprises a carrier for supporting an infant, the carrier constructed and arranged to safely contain the infant and to support an adult, a carrier frame supporting the carrier, a base supporting the carrier frame, connecting member rotatably connecting the carrier frame to the base, a drive member mounted on the base for rotating the carrier and transmission member for connecting the drive member and the carrier, the device being constructed and arranged to safely contain and continuously rotate the infant when the drive member is electrically engaged to provide a pacifying effect on the infant, and the device being constructed and arranged to safely support an adult and to have the carrier free to rotate manually when the drive member is electrically disengaged. A method of pacifying an infant by providing a continuously rotating carrier.

Abstract: A device for aligning multiple shaft segments which are coupled together to form a single rotating shaft. The device has two elongate cylindrical bars each having an annular, axially extending outer surface, one end by which it is rotatable, and the other end which is engagable and disengagable to the other cylindrical bar. One of the bars is inserted into an aperture of one of the shaft segments and the other bar is inserted into the other one of the shaft segments. The engageable and disengagable sections of the bars are arranged such that when the bars are engaged the force of the bar that is rotated is transferred to the other bar and when the rotated bar is rotated from the engaged position the bars are not in contact.
