Abstract: A hand writing instrument is provided with a built-in stamp (51) and built-in stamp pad (36). The stamp (51) and stamp pad (36) are respectively provided in carriers (50, 38) which are pivotally mounted on a mounting shaft (32) in such a manner that, in the rest position, the stamp (51) and stamp pad (36) lie against each other. In the working position, the stamp carrier (50) is pivoted about a position perpendicular to the mounting shaft (32) under the influence of a spring (52). Similarly, the stamp pad carrier (38) is pivoted about an approximately perpendicular position under the influence of a spring (42). The stamp carrier (50) and the stamp pad carrier (38) are movable between a stamp position and a rest position via a cap (18) which is displaceable axially with respect to the mounting shaft (32).

Abstract: A method of applying an athletic mat to a base surface comprises the steps of spreading a layer of rubber particles on the base surface. Although there may be some preparation (e.g., cleaning, material removal, etc.) of the base surface before the first layer of rubber particles is spread thereon, the first layer of rubber particles is applied without the necessity of a tack coating or primer layer. A first layer of binder is applied over the previously spread layer of rubber particles, with the binder having a viscosity to at least partially permeate through the layer of rubber particles. Accordingly, the first layer of rubber particles is bonded to the underlying surface when the first layer of binder dries. A separate, second layer of binder is applied over the first layer of binder preferably while the latter is still wet.

Abstract: In a writing implement with two cartridges (12,22) the housing is divided in two parts connected together by a pivot. The cartridges are pressed by spring force against cams (14a,24a) which are arranged on the other housing. The cams have such a profile that the writing points (12a,22a) are driven out in the opened position of the housings but retracted in the closed position into the housings. The closing action retracts the writing points into the housings; the opening out action drives out the writing points.

Abstract: Inertia pens, or writing or marking devices wherein the writing or marking element is shifted into the operating position by axial impulse. The kinetic energy of the impulse is transmitted to a calibrated mass slide within the pen which slide transfers its energy to the writing or marking element. A return spring is provided and the pen may be simple, compound, binary or multifunctional. The mass slide obviates the need for a push button or other manual actuator, and therefore writing or marking elements may be provided at both ends. The pen is refillable and retractable.This is a divisional of application Ser. No. 94,759, now U.S. Pat. No. 4,315,695, filed Nov. 16, 1979.

Abstract: A knock-out type mechanical pencil has a supporting rod mounted with an eraser at its rear end and axially slidably engaged within the interior of a cylindrical knock-button. A tubularly cylindrical weight is axially slidably engaged around the supporting rod. A cylindrical magnet is axially magnetized and secured to the inner peripheral surface of the knock-button. An annularly inwardly raised guide portion is formed on the inner peripheral surface of the knock-button for guiding the weight to the axial line of the knock-button when the weight is axially slidably dropped downwardly toward the writing tip of the pencil. To protrude and fix an eraser from the rear end of the tubular cylindrical body, the rear end of the pencil is tilted downward. To automatically contain or retract the eraser in the knock-button, the writing tip of the pencil is directed downwardly in writing state.

Abstract: A flat, multi-element writing instrument is described in which each writing element is attached to a glide element, a portion of which projects through a longitudinal slot in one face of the instrument's body for manual actuation. The longitudinal slots are located adjacent the side edges of a clip overlying one of the flat faces of the instrument's body. The glide elements include portions which underlie the clip and are received in respective channels formed in the undersurface of the clip, to interlockwith catches formed in these channels and hold their associated writing members in an extended, writing position. A cam within the writing instrument is positioned to have portions in the path of travel of each glide element so that, when one glide element is at least partially moved towards a writing position, the cam automatically pivots to move out of its path of travel and into the path of travel of another glide element to prevent its associated writing element from being extended.
