Patent number: 10494304Abstract: A calcium silicate insulation product includes a calcium silicate hydrate matrix that is predominantly but not substantially all xonotlite, for example 51-90 weight percent xonotlite and 10-49 weight percent tobermorite. The insulation product also contains wollastonite, and may include fines of lime and silica and reinforcing carbon fibers. A method of producing the insulation product includes providing the components of the insulation as dry solids, blending the dry solids with water to form a slurry, filter pressing the slurry to form a pressed shape, and curing the pressed shape under steam pressure only until the desired proportions of xonotlite and tobermorite are achieved in the calcium silicate hydrate matrix.Type: GrantFiled: May 23, 2017Date of Patent: December 3, 2019Assignee: Johns ManvilleInventors: Ames Kulprathipanja, Rick Lee Dolin, Noel Camp

Patent number: 10364932Abstract: According to one aspect, a hybrid high temperature thermal insulation includes a mix of inorganic granules. The granular mix includes at least 70 weight percent porous inorganic granules in the form of expanded perlite, and at most 30 weight percent second porous inorganic granules other than expanded perlite. The hybrid insulation also includes a binder. In example formulations, the second porous inorganic particles may be made from crushed aerogel, from fumed silica, from precipitated silica, or from other substances. The hybrid insulation may be formed into preferred shapes, for example a board shape or a semi-cylindrical shape configured to fit over a round tube of a predetermined diameter.Type: GrantFiled: January 30, 2017Date of Patent: July 30, 2019Assignee: Johns ManvilleInventors: Ames Kulprathipanja, Rick Lee Dolin, Severiano Almidon Lopez

Patent number: 5265503Abstract: A lug nut and socket wherein the socket and nut engage only selected point surfaces. In one aspect of the invention the socket has a decreased number of point surfaces. In another aspect of the invention, the lug nut has a decreased number of point surfaces. In another aspect of the present invention the socket points surfaces include point pins which are positioned to engage a pair of diametrically opposed point surfaces on the lug nut. The point pins are removably inserted into point pin wells extending into the lug nut socket. In another aspect of the present invention a retainer ring is provided to prevent the removable point pins from falling out during operation or handling, or otherwise being unintentionally removed. In another aspect of the present invention, the socket bore which engages a lug nut during operation is deliberately oversized to allow for considerable play between the lug nut and the socket.Type: GrantFiled: August 3, 1992Date of Patent: November 30, 1993Inventor: Lee A. Dolin

Patent number: 5174702Abstract: A lug nut retainer that holds a lug nut in position proximate to a wheel lug hole to accept a stud extended through the wheel lug hole and for resiliently urges the lug nut onto the stud while allowing the lug nut to rotate to screw onto and off the stud. A resilient retaining clip is mounted onto the wheel to hold the lug nut in position near the wheel lug hole and to resiliently urge the lug nut towards the wheel lug hole. The retaining clip is fastened to the wheel lug hole by inserting an arm of the clip through two holes provided in the wheel. As an additional feature, a limit clip is provided that limits the motion of the retaining clip to decrease the likelihood that the retaining clip may be bent or damaged while allowing the retaining clip to be positioned on a nut. The lug nut is provided with a socket stop ring around which the retaining clip is positioned. The stop ring keeps the socket from rubbing against the retaining clip.Type: GrantFiled: February 4, 1991Date of Patent: December 29, 1992Inventor: Lee A. Dolin
