Abstract: The inventive nib body for marking pen is a polygonally prismatic rod-like body made of a porous and rigid material suitable for penetration of the marking ink. Each of the ridge lines formed between the polygonal, e.g. triangular or quadrilateral, end surface and the side surfaces serves as the line-drawing edge so that, when each of the edges has a different length from the others, lines of different widths can be drawn with different line-drawing edges by use of a single nib. Further, the line-drawing edge can be provided with one or more of notches and divided into sections so that the edge can be used for drawing, for example, a double-track line composed of two parallel lines.

Abstract: A writing implement for generating a pair of lines which will vary in spacing depending upon the down pressure applied includes a handle, a pair of elongated blades of flexible material which are secured at one end to the handle and which project therebeyond. The blades have their minor axes intersecting at an angle of approximately 45.degree. to 135.degree., and marking elements are secured to the free ends of the blades and project therefrom with the points thereof being closely spaced in the unflexed condition of the blades. When the user applies downward pressure to the writing implement, the blades flex along their longitudinal axes, and this moves the points of the marking elements apart to generate a pair of spaced lines. Various types of marking elements may be replaceably seated in barrel portions at the free ends of the blades.

The container preferably comprises a hollow right angle prism divided by a slidable, self-supporting partition or partitions parallel to the longitudinal axis of the prism and pistons or plungers attached to the slidable partition or partitions and a slidable lug operating through a slot in the container wall to slide the partition with the attached plungers upwardly or downwardly to push the adhesive ingredients out of the container or return them into the container.

Abstract: This application discloses multi-color marking implements (i.e. crayons) having variegated color patterns, and a method and apparatus for their manufacture involving consecutively casting small amounts of molten crayon-like materials into suitably shaped molds at specific temperatures. The marking implements have a multiplicity of discretely-colored regions of random shape, randomly distributed in the implement. In addition, the marking implement may include a multiplicity of non-discretely colored regions resulting from a blending of colors from two discretely-colored regions. Optionally, the multi-color implement may be provided in a transparent lipstick type container that may serve as the mold in the casting process.

Abstract: A writing instrument comprising a plurality of coaxial writing nibs and means for advancing and retracting the nibs relative to one another to adjust a selected nib into an operative writing position, whereby the instrument is adjustable to produce lines of different predetermined widths.

Abstract: A modular writing instrument cap system is disclosed, in which each individual cap comprises an elongated tubular portion having an open end and a closed end. Near the closed end the cap is internally provided with a seal member adapted to seal with a writing instrument holding quick-drying ink. Near the open end, the tubular portion is internally provided with a catch for removably securing the cap on a writing instrument. Externally on the closed end, the cap is provided with a transversely-oriented open ended tubular barrel. The barrel is configured to receive an internally threaded sleeve, terminator rings and screws which thread towards one another through the rings into the opposite ends of the sleeve in order to hold the assembly together and secure a bail to it. The ends of the barrel and corresponding ends of the terminator rings are cooperatively notched to accommodate the legs of the bail.

Abstract: An electronic apparatus has a ball-point pen as the recording means and rotatably supports a roll of printing paper on a shaft provided on the side surface of the main body of the electronic apparatus, wherein the shaft to support the printing paper is made hollow inside, a cap is fitted in each opening at both ends of the shaft in a freely openable and closable manner so as to enable spare ball-point pens and a ball-point pen removed from a carriage of the electronic apparatus, when it is not in use, to be housed inside it.

The spotting member is formed of an elastic material having a number of communication pores for directing the ink therethrough from the one end to the other end of the spotting member.

Abstract: A pen of the embouchure type having a pair of contiguous nibs for a writing tip comprising at least one pair of shaped lips forming a curvate capillary mouth and being flexible to permit a slit formed by the lips to vary in breadth with the pressure applied upon the tip to produce an ink track of corresponding breadth; such a pen formed of flexible material with strengthening structural formations; and such a pen in which a plurality of writing tips may be formed at the nib end; the multitipped nib end being formed either from a tube or tubes of flexible material or from a sheet or sheets of flexible material.

Abstract: A pen having a hollow barrel with an open end and a closed end and two ink tubes in the barrel having one end secured to the closed end and having the other ends of the ink tubes extending through the open end, a ball extending out of the end of each ink tube, the ink tubes being free to twist upon each other in the said open end, thereby providing an interesting pattern in writing.

Abstract: An article for depositing a hot wax substance on a substrate in a desired pattern and which article includes a bowl having a reservoir for retaining the hot wax substance in a relatively liquid state. A spout extends outwardly from the housing and has a capillary tube connected to the spout and extending into the reservoir and terminating near the bottom wall of the reservoir. Moreover, this capillary tube has a relatively small diameter so that when the wax is in a heated state it will tend to rise in the tube by capillary action. When the reservoir is tipped so that the spout is pointed downwardly, the wax will flow through the spout and onto the substrate from the reservoir by means of a siphoning action. In a preferred aspect of the invention, a retaining tube extends through the reservoir in heat conductive relationship with the capillary tube. This retaining tube is designed to receive a heater element.

Abstract: Two opposing fingers of a robot hand are each provided with an array of optical devices which are capable of being in optical communication with one another through the gap between the fingers. One finger is provided with an array of light emitters and the other is provided with an array of light recepetors. By taking advantage of the motion of the robot hand and the small size of the optical devices, the shape of an object between the fingers can be detected by using at least one linear set, and preferably at least two linear sets, of devices in each array. Illustratively, the linear sets form a T-shaped array or a U-shaped array and are disposed along the edges of the fingers. In one embodiment the emitters are GRIN rod lenses coupled through a fiber cable to a light source, and the receptors are also GRIN rod lenses coupled through a fiber cable to a camera system. A manufacturing method utilizing such a sensor to identify the shape of objects is also described.
