  • Patent number: 4669702
    Abstract: The disclosure is related to a high pressure fluid control valve including a valve seat made from a resilient, deformable material and a main valve plug which is matable with the resilient, deformable valve seat. A selectively, axially displacable valve stem is associated with the valve plug whereby a contact load placed upon the valve plug by the valve stem will cause the valve plug to be become imbedded within the deformable material comprising the valve seat when the valve is closed and thereby conform the deformable seat precisely to the contour and configuration of those portions of the valve plug which mate with the valve seat. In this manner, a precise zero-leakage mating is obtained each and every time the plug is mated with the seat. In accordance with the invention, an auxiliary throttle plug is associated with the main valve plug and is arranged to mate with a second, metal valve seat which is arranged in an area removed from the resilient, deformable valve seat.

  • Patent number: 4668110
    Abstract: According to the invention, an inexpensive antifriction bearing is located in a plastic block and the plastic block is encircled by a further plastic ring. The softening point of the plastic ring is lower by 20.degree. C. than that of the material of the bearing block and between the softening point and melting point of the ring a difference of at least 30.degree. C. exists ensuring that in case of excessive warming up of the bearing, the sliding on each other of the plastic block and of the outer plastic ring as plain bearing, puts the bearing out of action for a certain time. The contact surfaces of the bearing block and the ring are spherical, ensuring the compensation of possible eccentricity by self-aligning. The ring is fixed in the seat of a roller by flanging. The invention renders superfluous the otherwise indispensable high-precision single-purpose machine or horizontal lathe for boring the roller, and makes possible the application of the technology of mass production.

  • Patent number: 4662073
    Abstract: An infinitely variable drawing instrument for producing unlimited varieties of fanciful designs. The designs produced by the drawing instrument are of the repeated individual line type yet indexed around the circumference of a circle. After the various apparatus variables are set by the operator and a piece of paper is located on a drawing platen, the drawing tool or pen nib, located at the end of a drawing bar connected to the driving wheel is placed on the paper and the operator merely rotates the driving wheel by grasping a handle. The simple manual rotation of the driving wheel causes the drawing platen to rotate and, in addition, causes the drawing tool or pen nib to move and thereby draw the fanciful design on the paper. Thus, repeated lines, indexed on a circle, produce unlimited drawing designs. A guiding template and/or an intermediate bar can also be connected between the driving wheel and the drawing bar which provide additional variables for adjustment for making additional drawing designs.
