A printing pad machine that can print a 360 degree image on a cylindrical object. That objective is achieved by modifying a conventional printing pad machine. The modifications include using a single angled print pad having a contact wall having a first height, a lower wall having a second height that is less than the first height, an angled surface interconnecting the contact wall's distal end and the lower wall's distal end, and a base wall interconnecting the contact wall's proximal end and the lower wall's proximal end and connectable to a base. Another modification includes a flexion-extension hinge positioned between the support member and the base or the support member and the overhead gantry and controlled by the adjustable and moveable actuator system and power source. That objective can be accomplished with the conventional printing pad machine using the single angled print pad.

The modifications include using a single angled print pad having a contact wall having a first height, a lower wall having a second height that is less than the first height, an angled surface interconnecting the contact wall's distal end and the lower wall's distal end, and a base wall (a) interconnecting the contact wall's proximal end and the lower wall's proximal end and (b) connectable to a base. Another modification includes a flexion-extension hinge positioned between (a) the support member and the base or (b) the support member and the overhead gantry and controlled by the adjustable and moveable actuator system and power source. That objective can be accomplished with the conventional printing pad machine using the single angled print pad. Both objectives can also be accomplished by adding ridges to the single angled print pad.

A modified ink cup for plate printing is presented, where the ink cup is separated internally into two domains, a storage area and a print area, by a baffle system. The baffling allows only a limited amount of exposure of the ink in the ink cup to the outside air, reducing evaporation of the ink solvent and extending the life of the ink supply in the cup. This system greatly reduces the number of times an ink cup has to be re-filled to perform plate printing and limits the evaporation of possibly toxic solvents to the air.

Light emitting rigid fracturable projectile-type marking ammunition are provided. The ammunition is a phosphorescent ball in the form of a spherical pellet or capsule that includes non-phosphorescent impact diffusing materials intimately admixed with phosphorescent materials. Non-phosphorescent pigments, fillers, and surfactants may also be included. The light emitting phosphorescent ball provides a luminous trail when discharged from the paintball gun and thus, may be used effectively in the dark.

Paintball gun and light emitting projectile-type ammunition for use therewith

Light emitting rigid fracturable projectile-type marking ammunition and reusable resilient projectile-type ammunition are provided, along with kits of the ammunition with an exciter and optionally a paintball gun. The ammunition is a phosphorescent ball in the form of a spherical pellet or capsule that includes non-phosphorescent impact diffusing materials intimately admixed with phosphorescent materials. Non-phosphorescent pigments, fillers, and surfactants may also be included. The light emitting phosphorescent ball provides a luminous trail when discharged from the paintball gun and thus, may be used effectively in the dark.

Phosphorescent paintball and kit including phosphorescent paintball,

Light emitting rigid, fracturable projectile-type marking ammunition is disclosed. The marking ammunition is in the form of a phosphorescent paintball. An exciter is adaptable for use with paintball guns to excite the phosphorescent paintball to emit light. The exciter couples to the muzzle of a paintball gun. The light emitting paintball provides a luminous trail when discharged from the paintball gun. A paintball according to the instant invention comprises a spherical pellet or capsule defining an interior chamber, and a filler contained in the chamber. In one embodiment, the capsule is impregnated with a phosphorescent material. In an alternative embodiment, a phosphorescent material is mixed with the filler. The phosphorescent material absorbs light when exposed to a light source, and after the light source is removed, emits light. A paintball being discharged from a paintball gun enters the exciter. Upon detecting the presence of a paintball, the exciter is triggered to produce a high intensity light. Light is absorbed by the phosphorescent material. After the light is removed, the phosphorescent material continues to emit light. Paintballs according to the instant invention discharged through the exciter provide a luminous trail and thus, may be used effectively in the dark.

A housing has a magnetic block therein with (preferably) an exposed side. The housing has (preferably) an integral, annular, curved, elastomer skirt forming a suction cup. The suction cup is used to attach the magnetic block to the external side of an oil passageway, e.g. an engine oil filter cartridge, such that the exposed side abuts, or nearly abuts, the passageway, the exposed side being a centralized base of the suction cup. The magnetic lines of force emanating from the magnet penetrate beyond the wall and attract magnetically attractable particles from oil passing thereby. The particles are held against the side opposite the magnet.
