Patent number: 8733045Abstract: Disclosed are apparatus and corresponding methodology for providing a base support, such as including concrete, and used such as for a wind-driven generator. Precast concrete cylinders are stacked in place upon a platform that may be partially precast and partially cast in place during assembly and supported, in certain embodiments, by plural concrete legs, the other ends of which are supported on a unitary or subdivided concrete foundation. In other embodiments, the platform may be supported by ribbed concrete panels. The concrete cylinders are glued together using an epoxy and then secured by an internal vertical post tension system extending from the platform to the upper most cylinder. Different types of concrete are used between upper and lower sections of the stacked cylinders. The lower section uses reinforced concrete while the upper section used ultra high performance fiber reinforced concrete.Type: GrantFiled: May 2, 2013Date of Patent: May 27, 2014Assignee: Tindall CorporationInventors: Bryant Allan Zavitz, Kevin Lee Kirkley

Publication number: 20110241246Abstract: An expandable molding insert apparatus and corresponding method are provided. The insert apparatus may be expandable between a first uncompressed position with a first diameter and a second compressed position with a second, larger diameter due to axial decompression and compression, respectively, of the insert apparatus. For example, the insert apparatus may include an inner rod, an outer jacket, and a compression member. The compression member may be configured to provide axial compression to the outer jacket, such that the outer jacket may be adjusted between a first uncompressed position with a first outer diameter and a second compressed position with a second, larger outer diameter. The insert apparatus of the present disclosure facilitates withdrawal of the insert apparatus from a molded component, requires a minimal number of mechanical components, and provides for ease of actuation when the insert apparatus is utilized during a molding process.Type: ApplicationFiled: April 4, 2011Publication date: October 6, 2011Applicant: TINDALL CORPORATIONInventor: Roger C.
