Abstract: The present invention concerns a method for controlling writing instruments, in particular ball-point pens, on paper, which consists in guiding the writing instrument relative to the paper plane in a repeated movement and displacing the paper in forward direction. The movement are thus coordinated so that the line obtained forms a meandering pattern which consists in rectilinear trajectories. The invention also concerns the device for implementing said method.

Abstract: A valve is disclosed for selectively permitting passage of fluid media such as gaseous fuel, from a first location to a second location. A valve body has one end portion defining a cylindrical inner wall surface and a flat annular seat extending inwardly thereof. An end plug is positioned for axial movement toward and away from the valve seat and an annular seal ring is positioned between the end plug and the valve seat and adapted to provide gaseous sealing contact between the end plug and the valve body at a plurality of locations when the end plug is moved to a first closed position which prevents gaseous communication between the first and second locations. In one embodiment the seal ring moves axially with the end plug and in another embodiment the seal ring remains seated and the end plug moves in the axial direction away from the seal ring. Other embodiments provide alternative means to direct the gaseous media from the first location to the second.

Abstract: In a shaving instrument including a razor blade having an edge attached to one end of a support and a guard bar arranged in precise spaced relation parallel to said razor blade edge, the improvement of a patterned texture on a region of an outer surface of the guard bar, the texture including one or more depressions each having a mound of minute height which constitutes a border of each depression, the material of each mound formed by a solidified part of the material which was melted and displaced from the guard bar to form the depressions; the texture being positioned such that when the shaving instrument is slidingly applied to skin having hair extending therefrom, the texture exerts a degree of drag or friction thereto which causes the skin to be pulled slightly and the hair to be properly positioned for cutting by the blade edge. The texture is imprinted upon the guard bar by a high energy beam, preferably from a YAG-Nd laser.

Abstract: The invention relates to an apparatus and method for the uniform treatment of the surfaces of a plurality of individual parts when such parts are processed as a single heap by introducing a mass of parts into a vessel where they form a heap; introducing a treatment medium into the vessel; repeatedly separating and dispersing the parts from the heap and then returning the parts back into the heap in during controlled cycles so that all surfaces of the parts to be treated are exposed to and contacted by the treatment medium. While the parts are separated and dispersed from the heap, the treatment medium is forced around, through and out from the parts so that, after a number of cycles, all surfaces of the parts are uniformly treated by said treatment medium.

Abstract: A fuel burning lighter, optionally having an adjustable flame height, comprising a supply of liquified gaseous fuel burner means communicating with the fuel supply, valve means positioned between the fuel supply and the burner means, means to provide first force to retain the valve means in a closed position to prevent gaseous fuel from passing therethrough, and means to provide second force less than the first force biasing the valve means toward an open position. The second force providing means normally provides sufficient force to move the valve means to an open position when the first force is relieved or released from acting upon the valve means.

Abstract: A fuel burning lighter having an adjustable flame height comprising burner means, a supply of liquified gaseous fuel, valve means positioned between the fuel supply and the burner means, and a film having a plurality of micropores oriented substantially perpendicular to its surface. The film is positioned between the valve means and the fuel supply in such a manner so that all fuel flowing to the burner means must pass through the micropores. The lighter also includes means for conducting fuel passing through the film through the valve means to the burner means, and control means to selectively increase or decrease the passage of fuel through the film to the burner means so as to provide a flame of desired height.

Abstract: Liquid gas-operated lighter, particularly pocket lighter, comprising a burner tip, a fuel tank, and, arranged therebetween, a non-adjustable control device for the flame height. The control device is provided with a fuel-permeable proportioning disk of microporous film which, on the side facing the fuel tank, is tightly braced in its border region by means of a bracing disk having a passage for the fuel, and, on the side facing the burner tip, rests against a component having a gas-permeable layer, the bracing disk (15) forming the conclusion of the lower end of the control device (12, 13, 14, 15, 16). In the vertical position of use of the lighter, this end is always located at a distance above the liquid phase of the liquid gas. The space between the control device and the liquid level (21) is free from structural components.

Abstract: Liquid gas-operated lighter, particularly pocket lighter, comprising a closable valve at the opening of a valve bore which valve is in communication with a burner tip, a fuel tank and a non-adjustable control device for the flame height arranged between tank and valve bore. The control device is provided with a fuel-permeable proportioning disk of porous material which, on its side facing the fuel tank, is tightly pressed in its border region against a surface which is ring-shaped, preferably circular ring-shaped, by means of a structural component having a passage for the fuel. The annular surface (13) surrounds a recess (12a), which has an end face; the end face, together with the recess and the proportioning disk (14), forms a proportioning chamber which is in communication with the burner tip (4) exclusively through the valve bore (11).
