  • Patent number: 4088132
    Abstract: A hydrophilic polyurethane foam for use in a catamenial device such as a tampon is disclosed which can be compressed to less than about 50 percent of its original dry volume, stored in such condition for an extended period of time, and later rapidly re-expanded to at least its dry volume. Prior to compression, the foam is impregnated with a solid inorganic release agent, which is located within the cells of the foam and maintains the separation of the cell walls. Adherence of contiguous cell walls is prevented and the rapid re-expansion of the foam upon contact with moisture or water is thereby facilitated.

  • Patent number: 4078457
    Abstract: The present novel inventive method of grinding the raking surfaces of a blade of a circular saw includes the steps of positioning a rotating frustoconical grinding element in two-directional movable relationship to a fixed plane of reference such as a work bench; positioning the major plane of the circular saw in a position which will permit a tangential approach of the frustoconical grinding element to the raking surfaces of the blade; moving the grinding element into abutment with the raking surface of one tooth of the circular saw; pressing the outer surface of said rotating grinding element against said raking surface; utilizing manual pressure in order to obtain a concave surface having a progression of change of radius in which the tangent angle of said change of radius is between two and ten degrees and abrading said raking surface so as to form a concave configuration therein having a graduated depth terminating at a maximum of 1/32 of an inch measured in relation to lateral, radially directed leading

  • Patent number: 4078491
    Abstract: A portable imprinter for transferring indicia from a printing plate to a document comprising a generally rectangular base adapted to support the document in printing disposition over the plate, a frame mounted on the base, a pair of longitudinally extended slots located on opposite sides of the base at its junction with the frame for insertion of the printing plate and the document, and an imprinting roller assembly comprising a generally rectangular reciprocable carriage movably mounted within said frame, a printing roller supported within a U-shaped bracket, said bracket pivotally retained within said carriage on the side thereof juxtaposed to said base, and a rectangular cover mounted on said carriage on the side thereof opposite said bracket, wherein said bracket is under spring bias, placing said roller in constant contact with said base. During the printing cycle, the bracket pivots into rigid abutment with the cover to provide printing tension to the roller.

  • Patent number: 4077409
    Abstract: A catamenial device such as a tampon which comprises a segment of a rapidly reexpandable hydrophilic polymeric foam held in compression to less than 50 percent of its original dry volume and a constraining means holding said segment in compression which is adapted to provide lubrication for insertion of said segment into an animal's body cavity and to thereafter rapidly disintegrate, wherein said constraining means comprises a capsule possessing a plurality of perforations distributed about its surface to hasten disintegration. The devices of the present invention may be stored over an extended period of time without the difficulty of premature escape of the segment from the capsule.

  • Patent number: 4057905
    Abstract: The following disclosure relates to a device for the securement of a sighting instrument within the bore of a shotgun in which the present device comprises: a main shaft; means for a spring-biased reciprocal movement which is axially secured about said shaft; a muzzle stopper having a partially cone-like contour including a circumferentially formed finger-grip therein, the stopper being axially secured about said spring-biased means such as to create a potential for hypodermic-like reciprocating movement of the stopper with respect to the main shaft; an end cone disposed at the end of the shaft opposite to that end proximate to the finger grip of the muzzle stopper; and three resilient ball-bearing rods, each having bearings at the same one end thereof, each of said rods situated about said shaft at 120.degree.

  • Patent number: 4056278
    Abstract: The present invention relates to a device for retrieving waste deposits and, more particularly, animal excrement and the like. The device includes an outer tubular shaft having a handle portion formed in the shape of the handle of a walking cane. An inner shaft is concentrically disposed within said outer shaft and is moveable longitudinally with respect thereto. Such longitudinal movement of the inner shaft causes a tension spring to bear against a normally-open hinge which, in the absence of circumferential force thereabout, will exhibit its normally-open position. Longitudinal movement of the inner shaft away from the handle will cause said tension spring to bear against the hinge thus permitting said hinge to open selectably as may be desired. After opening, a throwaway box is attached to the fingers of the hinge and, through an upper movement of the inner shaft, the retrieval of an animal deposit is achieved.
