摘要： A pen tip structure for a ball point includes a ball socketed between a pipe tip and the end of an inner core, the end of the inner core having a flat center surface for supporting the ball and an annular lip which flares outwardly from the flat center surface to create a capillary gap between the ball and the pipe tip. Ink is supplied to the ball from a capillary ink flow channel between the inner core and the pipe.

摘要： A writing tip 1 for use with aqueous ink comprises an elongate housing 2. A writing ball 3 is retained in a socket 4 at one end 5 of the housing and a fibrous feed core 6 having aqueous ink feeding capillaries extends into a bore 7 in the housing from the other end 8. The core 6 acts to transfer aqueous ink from a source to the ball via a grooved feed passage 9 between the bore 7 and socket 4 and in order to provide releasable transfer of ink between the core 6 and the passage 9, the core is inserted into the end 13 of the passage, the material of the core being substantially uncompressed within the grooves 12 of the passage 9 and assuming substantially the cross-section of the passage at least at the end 13.

摘要： A ball-point pen tip provided with a tubular ink guide portion formed of metal. The ink guide portion is formed with radial projections extending radially inwardly produced by the pressing deformation of the metal tube. These projections define capillary channels between neighbouring projections and a ball seat at their radially oriented surfaces. An ink guide stem disposed in the tubular ink guide portion has one end in contact with at least one of the projections, and has the other end confronting with an ink supply stem inserted in a holder. The holder and the ink guide portion provide a socket of the pen tip. Such pen tip is applied to a ball-point pen which includes an ink reservoir adapted to be connected to said ink supply stem. Such ball-point pen employs an aqueous solution based low viscosity ink.

摘要： A sphere particularly suitable for ball point pens having a core capable of withstanding temperature in excess of 800.degree. C. and a chemically vapor deposited coating on the core, the combined diameter of core and coating ranging from approximately 0.5 to approximately 1 mm in diameter. For example, the core may consist of a metal such as tungsten, nickel, copper or molybdenum; or alternatively the core may consist of a ceramic such as aluminum oxide or graphite. The vapor deposited coating may consist of a metal carbide such as tungsten carbide, titanium carbide, tantalum carbide or niobium carbide. Alternatively the coating may consist of a metal boride such as titanium diboride.

摘要： An angled ball tip for viscous fluid applicators which is adapted to be used with a hand-held reservoir for applying paints and other viscous fluids to cloth, wood, and the like, including a hollow housing and a spring-loaded ball disposed within said hollow housing. Pressure placed on the ball when coming into contact with a cooperating surface causes the ball to recede allowing the viscous fluid to flow around the surface of the ball and deposit on the surface.
