  • Patent number: 10208828
    Abstract: A compensating damper comprises opposed working end faces (1788), a hermetically sealed chamber between the working end faces, and a set of plates (1701) in the chamber with a film of viscous fluid between each pair of adjacent plates. The damper has at least two different film thickness zones across the set of plates, each of the different film thickness zones providing a different resistance response when acted upon by an outside force exerted on at least one of the opposed working end faces. Multiple internal guide pins (1723) may extend axially from the opposed working end faces for engaging the plate stack partially from each of said working end faces to increase the stroke while providing for a compact damper. The plates may have a conical configuration to providing dampening in different plans.

  • Patent number: 10143145
    Abstract: An apparatus and method for controlling apical growth of plants without cutting or pinching so as to increase productivity and efficiently utilize growth resources. A coiled frame is provided having the form of mirror image/opposed Fibonacci or Golden Spirals that expand from a first starting point and then contract back to a second starting point by an approximately similar number of quarter-turns at a selected pitch, the spring suitably being formed of a single length of wire. The apical growth tip of the plant is bent to meet the frame at selected locations and attached progressively as growth proceeds, using ties or other connectors. A stake inserted through the starting points of the spiral attaches the frame to the medium in which the plant is rooted. The stake is preferably angled so that the plant maximizes utilization of available light, for example, approximately 80° to the surface of the medium.

  • Patent number: 10060234
    Abstract: A low-debris low-interference semi-solid well perforator having selectively variable free volume and method for providing such is disclosed according to one or more embodiments. The perforator may include a charge tube holding an independently floating axial stack of selectively variable divider segments, each having one or more concavities formed in upper and lower sides. The segments are arranged so that concavities of adjacent segments form sockets, into which shaped charges are located. The segments provide support to minimize deformation of shaped charge cases yet provide less than 360 degrees circumferential contact about the shaped charges to form selectively variable voids for collecting debris and spall resulting from detonation. The voids and floating segments attenuate detonation shock interference. A debris guard prevents debris from entering the wellbore. Relieving slots in the debris guard attenuates transmission of shock interference through the debris guard.
