Abstract: Relates to a pocket-type writing instrument, employing an extruded rod-like writing element composed of a homogeneous thermoplastic composition having a formation of longitudinally extending ink-conducting channels around an axial channel, one end of said element constituting the writing point and the other being in contact with a body of ink, usually carried in an absorbent material contained in the barrel of the pen. Provides novel means for preventing axial displacement of the writing element without damage to or constriction of the ink channels therein and without the use of wire pins which may interfere with the ease of handling of the instrument.

Abstract: Brush-pen of round and flat hair and permanent liquid ink of adjustable flow for drawing and writing, including a container on the upper part of the outer body of the ferrule. This container is provided with a cap with a controlling device, into which the desired liquid ink is introduced. The ink goes through an orifice of the upper part of an outer cylinder of the ferrule and through a winged guide cap of an inner cylinder of the ferrule. The inner cylinder contains a piston provided with a pressure shaft controlled by the controlling device of the cap so as to provide adjustment of the passage of ink through a hollow needle of the ferrule. This maintains a constant flow of ink to the hair (brush) tip in the desired amount, doing without the need of inkpots. The alternating downwards and upwards movement of the piston keeps the channel constantly clean.

Abstract: A disposable diaper having an inside surface for direction toward an infant and an outside surface is provided with adhesive tabs, each tab having an adhesive coating on one face thereof. Each tab has a first end portion which is permanently attached to a marginal portion of the diaper outside surface by means of the adhesive coating, and an opposite end portion which is divided longitudinally into a central strip and a pair of marginal strips flanking the central strip. The marginal strips are permanently attached to a marginal portion of the diaper inside surface by means of the adhesive coating. A release layer is releasably adhered to the adhesive coating on the central strip and removable therefrom, whereby the central strip provides a securement means for fastening the diaper about an infant.

Abstract: A combination punching and binding machine for gang punching a stack of sheets and binding the sheets with a pre-curled plastic "comb-binding" element. The machine has a manually actuated lever which, when operated in one direction actuates the punches, and when operated in the opposite direction, laterally moves a comb upon which the binding element is placed, and then actuates a plurality of hook elements to uncurl the curled splines of the binding element for receiving the punched sheets.

Abstract: The head of a self-sharpening pencil is provided with a pair of pivotally disposed, cooperating abraders controlled by a pair of movable members. Means are provided for mechanically driving the graphite core against the abraders whereby the forward end of the graphite core is sharpened to a high degree before it is protruded for writing.
