    Abstract: Dimensionally-stable porous materials such as porous plastic are used in a variety of ways to provide uniform distribution and application of liquids to vegetation. Porous plastic can be readily cut, sawed and drilled to provide liquid distribution channels and various applicator shapes. Porous plastic is easily glued or welded for joining to other materials. Rods, tubes and handles are easily inserted into the porous plastic, and selected areas of the porous surfaces are readily sealed with glue or by melting to confine liquid application to selected areas. The pore size, preferably in the range of 5 to 200 microns, can be selected in accordance with the viscosity of the liquid and the desired rate of flow and pressure. Porous plastic can be highly abrasion resistant, which is especially useful for constructing applicators which rest upon the ground or pavement. Where abrasion is not a problem, the porous plastic may serve to distribute liquid to a soft absorbent applicator such as a sponge.

    Abstract: A writing implement for use in numerically controlled drafting machines has a tip with a front end face which is maintained at a distance of a fraction of one millimeter from the surface of a sheet of paper or another carrier of information by a portion of a ball which is rotatably mounted in a socket extending rearwardly from the front end face so that the surface of the carrier and the front end face define a capillary gap. This gap draws ink from the socket which receives ink from a channel extending into a reservoir in the housing of the implement. The channel contains several rib-shaped back supports each of which is in mere point contact with the adjacent confined major portion of the ball in the socket so as to center the ball in the socket whereby the confined major portion of the ball and the surface surrounding the socket define a capillary clearance, and to provide paths for the flow of ink from the channel into the socket.

  • Patent number: 4913175
    Abstract: In a liquid-applying tip assembly in which the liquid-applying member is pushed to operate the valve to allow the liquid to flow to the liquid-applying member, the liquid-applying member is a plastic member which comprises: a plurality of ribs extending radially and axially from an axial core in such a manner as to form a plurality of axial liquid passageways therebetween. A barrier is provided between the valve and the cylinder of the tip assembly, the barrier having a hole whose diameter is slightly larger than the outside diameter of the liquid-applying member to control the flow of liquid.

  • Patent number: 4906118
    Abstract: A lotion applicator is set forth including a central cylindrical container including a right and left flexible strap diametrically secured to opposite vertical sides of the container. The container is formed with openings for enabling deposit of topical lotion onto the dorsal portion of an individual. The straps include overfolded handles for manual grasping by the individual. The straps are further formed with enveloping impermeable layers adjacent the container to prevent undesirable application of lotion onto the straps when the apparatus is wound and secured within a carrying pouch. The cylindrical container is formed with diametrically opposed staggered rows of through-extending openings for application of lotion to the individual wherein the openings are oriented medially of the securement portions of the opposed right and left straps.

  • Patent number: 4838723
    Abstract: Flexible pen nib (20) for writing instruments includes a rod-like nib body having inner capillary channels (24) for passing ink therethrough. This nib body is a porous rubber-like elastic body having composite-fiber textures obtained by combining a number of longitudinally oriented crimped polyamide fibers (21), with synthetic resin elastomer (22). Those composite-fiber textures form, within the cross-section of the pen nib, random-shaped elements (23) which are arranged in a uniformly random aggregation leaving the capillary channels (24). The capillary channels (24) have an orientation in the axial direction of the pen nib, and provide the pen nib with a predetermined porosity.

  • Patent number: 4824271
    Abstract: A planar or plate-like nib for writing instruments has a plurality of separate ink feeding channels which are distributed in the widthwise direction of the planar nib, and a split at the end portion along the entire width thereof. The split provides a suitable flexibility to the nib and desirable writing with a predetermined thickness with clear marginal ends of written lines. Further, the split connects the separate channels with one another at the writing end portion of the nib so that a uniform flow of ink to the writing end portion of the nib is achieved.

  • Patent number: 4770558
    Abstract: In an ink writing instrument, the ink storage space is divided into individual chambers that are inside the housing and are arranged axially one behind one another. The chambers are connected with the writing point by an ink guide. The ink-filled chambers are emptied one after the other by capillaries in the ink guide, air entering the chambers by a ventilation duct in the mouthpiece and the capillary ventilation openings. When ink is removed, no enclosed air volume is formed inside the storage space. In a second embodiment, the chambers are emptied simultaneously, the ventilation duct being opposite the writing point.
