Abstract: Hand-held scraper includes a body or holder portion to which is removably secured a scraping or cutting blade. The blade is retained in place by camming the mounting tabs at its respective ends into tight frictional locking engagement with a pair of longitudinally spaced apart retaining ribs protruding downwardly in opposite outwardly disposed directions from the underneath side of the holder portion. At least one of the retaining ribs is somewhat flexible to facilitate camming of the blade into and out of assembled engagement with the holder portion with little or no flexing of the mounting tabs and no bending or yielding of the blade body whatsoever. To facilitate removal and replacement of the blade, a movable lever is provided on the underneath side of the holder portion inwardly of one of the mounting tabs. When the lever is manually pushed downwardly, the lever presses against such mounting tab, causing it to cam away from the associated mounting rib thus freeing the blade from the holder.

Abstract: A mask member is made from a thin, rubber, cloth-like material. The mask member is sized and shaped to fit about the face to extend rearward from the face to about the left and right ear areas and to extend in length from an upper edge to a lower edge. The upper edge extends along a line between the cheekbone area below the temples, along the lower part of the eye sockets, contouredly over the bridge of the nose. The mask member is unitarily formed with a nose piece contoured to fit over the nose. The nose piece together with the face mask are shaped to form a breathing aperture for the nostrils. A seam extends from below the nose piece downward to act as a front edge. The seam extends convexly from below the nose to the chin area to form a pocket for the lips and air, and arcuately inward under the chin to the lower edge. The seam selectively forms a channel in communication with the pocket. Aperture means are formed in the mask member proximate the mouth for breathing and speech.

Abstract: Disclosed is a unitary, disposable panty-type garment with an open crotch portion, intended for use by female patients undergoing gynecological examination. Also disclosed is a method of making such a garment by cutting from a web identical blank pieces which have wider and narrower portions in such manner that wider portions of a first blank are cut from a portion of the web adjacent to the portion from which narrower portions of neighboring blank pieces are cut. This saves material. Also disclosed is a concept of providing, as an article of manufacture, a two-blank portion of web which has adhesive or similar joining means provided at certain seam areas and dart areas, whereby there may be fashioned by the user a garment of appropriate dimensions.

Fabric sleeves may be employed around springs to improve the fluid integrity of the interior surfaces.Springs may also be used to join blood vessel segments by puncturing one segment of the blood vessel with a first end of a spring, coiling the spring therearound, puncturing a second segment of the blood vessel with a second end of the spring and coiling the spring therearound.

Abstract: An artificial limb consisting of a tube like member having an inner wall and an outer wall, each of flexible air impervious material sealingly joined together at respectively opposite ends of the tube and along at least three lines extending longitudinally of the tube. The longitudinal seams are spaced apart from one another providing a plurality of side by side air inflatable compartments. At least one compartment is provided with an air inlet passage means for inflating the artificial limb and the compartments are in communication with one another so that there is equalization of pressure in all of the chambers. The inner and outer walls are preferably a transparent plastics material and the tube tapers in a direction from one end to the other.

Abstract: A cleaning head for connection at bottom surfaces of a swimming pool to an automatic pressure control system includes a chamber and a rotary expansion collar disposed in the chamber. The collar has relatively thin cylindrical walls and an inclined slot extending through the cylindrical wall, allowing the collar to expand in response to increased water pressure produced by the pressure control system. The slot is closed when the collar is relaxed and is opened in response to water being forced under high pressure into an interior portion of the chamber surrounded by the collar. Water ejected from the interior portion through the open slot causes the collar to rotate. As the water pressure increases, the collar expands further until its outside surfaces frictionally engage the chamber wall, stopping rotation of collar.

Abstract: A release mechanism for use with an underwater exploration device such as one used to release ballast from an ocean bottom seismograph which includes primary and secondary release actuating devices. Ballast weights are secured to the seismograph by cables which themselves are secured by levers held immobile by a removable pin. The pin can be removed by the primary release actuating device, a rotary solenoid with linkage arms which produces a linear stroke, or by the secondary release actuating device, a coil spring held in compression by means of an electroplatable wire around and under the head of the pin, or both, allowing the levers to pivot releasing the cables and ballast weight. The mechanical advantage of the levers is utilized to allow a relatively heavy ballast weight to be held while requiring a much smaller force to remove the pin allowing its release.
