  • Patent number: 4086028
    Abstract: Rotary turbine ventilators, wherein the vanes are connected to the base ring of the rotary element by a crimping or swaging operation instead of by welding or riveting. The method of manufacturing the ventilators is particularly adapted to the manufacture of aluminum ventilators because of the saving of labor and cost which results when aluminum ventilators are made thereby, although the method may be used to manufacture ventilators of other materials.

  • Patent number: 4069088
    Abstract: Pipe wrapping apparatus of the so-called hand-wrapping type, having a rotating ring structure which carries spindle apparatuses, each carrying a roll of pipe wrapping tape. The apparatus includes take up spindles for accumulation of the backing stripped from tapes which have backing, and includes brake devices for controlling the tension at which the tape is wound onto the pipe. While the apparatus is of the so-called hand-wrapping type, it may be power driven. The apparatus also provides for applying a coat of primer or other precoating material onto the pipe prior to the application of the tape. A notable feature of the invention is the provision of self-balancing spindles through the use of which the tape is consistently applied to the pipe without wrinkles or other misalignments of the tape and with uniform overlap of courses.

  • Patent number: 4062354
    Abstract: Intracranial pressure transducer System, wherein a holding bracket containing and supporting sensor elements of the apparatus is surgically positioned, through an opening in the skull, against the dura of a neurosurgical patient. The elements within the holding bracket transmit signals in the form of radiated electromagnetic waves to a receiver located outside the body of the patient. The received signals may be recorded on magnetic tape, may be converted to audible sounds, and/or may be recorded on charts, or otherwise suitably preserved and/or presented for use in monitoring the intracranial pressure of the patient.

  • Patent number: 4027349
    Abstract: Apparatus for brush-cleaning the interiors of pipes, wherein rotative brushes are carried by a rotative carrier plate. The brushes are rotated by air motors, and rotate at very high speeds. The brushes are spring-loaded to consistently bear against the inside of the pipe wall, and are disposed at a small angle from radial which results in reduced brush wear and more efficient pipe wall cleaning.
