  • Patent number: 5056187
    Abstract: An attachment for a vacuum system which is utilized for cleaning the eave troughs of a building from ground level. The attachment is an arcuately-shaped at least semi-rigid tubular member which connects to an elongated at least semi-rigid extension tube of a vacuum system. The curvature and dimensions of the arcuate attachment allows the operator of the vacuum system to raise the arcuate attachment up to the eave trough and insert the free end thereof into the trough for purposes of cleaning the same. A mirror is mounted on the intrados surface of the arcuate attachment, which allows the operator standing on the ground to view the inner bottom surface of the trough which is being cleaned. The operator of the cleaning system can move the attachment through the length of the eave trough and suck all of the debris therefrom, while watching to ensure that no debris is left behind. The free end of the attachment tapers to a smaller diameter to facilitate mounting of other attachments thereto.

  • Patent number: 4993441
    Abstract: A disposable permanent wave rod which is comprised of an imperforate generally cylindrically-shaped member formed of a readily wettable rigid polymeric material, wherein, due to the inherent properties of wettable polymers, greater adherence is found to exist between the wettable permanent wave rod and the wetted hair and end paper which is wrapped theraround, thereby preventing slippage of the end paper from around the permanent wave rod. Such rods may be secured to a person's head by connecting each rod to an adjacent rod through the use of rubber bands or an elongated flexible but rigid thin strip of material, which may be tacked or adhesively secured to each adjacent rod.

  • Patent number: 4969670
    Abstract: Non-releasable, molded, large-diameter, corrugated plastic pipe having a wall structure made of high density polyethylene, PVC or polypropylene of sufficient thickness so as to be rigid but elastic and therefore relatively inflexible and having an integral automatically locking female coupling at one end and a cooperative male coupling at its opposite end, with access to its latching members at its exterior, and a method of manufacturing multiples thereof by a continuous molding process. The pipe has a corrugated wall structure. Only minor auxiliary cutting operations are required to separate portions thereof into individual plastic pipe sections, each having the automatic-locking coupling at one of its ends and a male portion at its other end. The coupling is supported on the corrugated pipe by a frusto-conically shaped collar which functions as a guide for proper alignment as two sections of such pipe are united into latched relation.

  • Patent number: 4935884
    Abstract: An apparatus for determining the length of an open or closed-end pipe by measuring the propagation delay of a sound pulse transmitted down the pipe bore. The apparatus includes an acoustic transducer, an acoustic detector and associated circuitry for computing the time required for an acoustic pulse to travel and return the length of a pipe. Electronic circuitry, including a microprocessor, is employed to provide the apparatus with an automatic gain adjustment feature. The gain circuitry increases the amplification until a return pulse of desired amplitude is obtained. The gain is time varying to make the last-to-return signals strongest thereby avoiding false readings from pipe discontinuities. Compensation is made for speed-of-sound variations due to temperature, humidity, and barometric pressure by direct measurement of speed of sound during each length measurement. The open or closed endedness of a pipe is determined by return signal charateristics and a correction factor applied for open-ended pipe.
