Abstract: Disclosed is an air hose holding device, particularly useful to people using air hoses while working on roof tops. During use, the base of the device is fixed to a mounting surface, such as a roof, with as few as two nails. The hose is then passed through an aperture in the device. An adjustable slip latch mounted above the aperture has a half-circle cut into it. By moving and fixing the adjustable slip latch closer to or farther away from the aperture, the adjustable slip latch covers more or less of the aperture, and the half-circle completes the circular shape of the aperture to make the aperture smaller or larger. Thus, different size hoses may be held in place with the single device. The device need only be mounted once for an entire job, since the hose may be pulled through and held at different lengths within the aperture of the device, by simply adjusting the slip latch.

Abstract: A lightweight, portable, adjustable folding chair accommodated specifically for persons with a joint disability which causes sitting or rising from a seated position to be difficult including partial or total hip replacement patients. The chair has adjustable height legs, solid cushioned seat and solid arm rests. The feet of the chair are covered with replaceable rubber tips for safety. The chair may be folded for transport and storage. A handle within the backrest is included for ease of carrying.

Abstract: The invention is an ergonomically constructed string instrument which is achieved by rotating both the nut and the bridge about a longitudinal axis in the direction from which the player's hand approaches, to the degree which is predetermined to accommodate a particular player. The invention addresses the high incidence of overuse or repetitive strain injuries suffered by players due to extreme wrist flexion.

Abstract: The invention is a tone producing device consisting of a tone source inside of an elongated cavity attached to at least one point of the object surrounding the cavity (such as the walls of a tube). The tone source can be any tone producing device including: (1) a length or lengths of musical string held under tension within the cavity, (2) one or more tines suspended within the cavity, or (3) an electronic tone producing device. When vibrating, the tone source transmits sound waves in four different ways: (1) sound transmitted from tone source to cavity wall; (2) sound transmitted from tone source to external soundboard; (3) sound transmitted by combination of tone source and cavity wall to external soundboard; and (4) electronic amplification to a speaker.

Abstract: The invention is an oral cleaning device incorporating a low power laser radiation source and means for producing pulsed or continuous wave delivery of low power radiation to teeth, gums and oral tissue. The device is used alone or in conjunction with a liquid jet or jets and/or with photosensitizer dental paste or liquid. The device destroys bacteria and viruses in the mouth and on surrounding tissue. It increases oral blood circulation and enhances the body's immune system response to oral infection. The device may be operated by a trained professional at three different repetition rate frequencies, selected by the operator to threat different dental conditions. The specific photosensitizer liquid or paste which is activated at a certain wavelength is chosen by the operator to treat different dental conditions. The device is also intended for home dental hygiene at low power.

Abstract: The invention is a device used to mark a point in connection with the installation of an indoor sprinkler system in a ceiling or wall such that the device is connected to installed sprinkler system piping and the telescopic pointer is extended to the necessary length to mark a point in the ceiling or wall where the sprinkler head should be installed or where connector piping should be installed.

Abstract: An improvement on hinges such that the side of the hinge which comes into contact with the door or door jamb is scored so as to remove a portion of the square hinge corners on the back side of the hinge to insert into a rounded hinge cut-out. The Two in One Hinge eliminates the need to manufacture rounded hinges. It eliminates the need to square off rounded hinge cut-outs so as to install a square corner hinge. It eliminates the need for the installer to utilize hand tools to square off the corners of a round hinge cut-out.

Abstract: A method of optically measuring volatile impurities in contaminated medium using a combination of a distillation process with head space analysis. The method uses a hydrophobic extracting membrane at the surface of an internal reflection element (an optical fiber or an attenuated total reflection crystal). The hydrophobic analytes are extracted into the extracting membrane, from the contaminated medium. By heating the contaminated medium to form a vapor and cooling the sensor element surrounded by the extracting membrane this invention significantly reduces the limit of detection by between two and three orders of magnitude from the prior art. The distillation aspect of the method also serves to protect the extracting membrane surrounding the sensor from damage by the mechanical impurities in the contaminated medium.

Abstract: A unique suspension device adapted to all styles and sizes of welded wire mesh concrete reinforcement fabric. The device rigidly suspends all schedules of reinforcing fabric in a predetermined, fixed parallel position with respect to the horizontal plane to which concrete is poured to form flat concrete slabs. The suspension device consists of a thin-walled bushing or ring composed of polyvinylchloride incorporating slots or cavities radially positioned at right angles to each other on its circumferal cross-section to accept, secure, and lock the reinforcing material into place to provide the desired level of suspension. The device maintains stacking characteristics in order to allow multiple parallel reinforcing fabric layering for industrial, high-stressed applications.
