Patent number: 9587893Abstract: A system and a method for promoting improved air flow through a cooling tower and reduced inner air pressure losses caused by rain in the rain zone of a cooling tower. Aerodynamic modules are mounted on the lower edge of the cooling tower shell in order to deflect the downward-flowing air about the lower edge of the tower shell and into the rain zone. The aerodynamic modules can be modularly mounted, can be replaced, and do not affect the statics of the tower shell. Aerodynamic modules can also be built on the base area to deflect the incoming air over any obstacles. Troughs or dripping elements can also promote flow by reducing the rain falling in an outer area.Type: GrantFiled: November 2, 2011Date of Patent: March 7, 2017Inventors: Pery Bogh, Peter Graf, Klemens Fisch

Patent number: 9587895Abstract: A bolt for a firearm having a rotatable head and carrier body has a twisted polygonal keyed interface between the head and carrier body. A neck extending rearward from the head presents the keyed interface with a corresponding bore within the carrier body. This construction reduces torque moments between the head and carrier body as compared to prior art bolts. Camming loads on the neck may be constructed with inverses to create space for tolerance and lubricant.Type: GrantFiled: January 19, 2016Date of Patent: March 7, 2017Inventor: Brian F. Abbott

Patent number: 9587898Abstract: A trigger mechanism guard assembly includes two arms, each having a first end with a trigger guarding surface and a second end and a housing with substantially parallel side surfaces configured to at least partially enclose the second ends of the arms. The housing is configured to be movable relative to the arms such that the housing has a first position and a second position, the second position being closer to the first ends of the arms compared to the first position. Movement of the housing from the first position to the second position causes movement of the first ends of the arms away from each other.Type: GrantFiled: March 22, 2016Date of Patent: March 7, 2017Assignee: Kargyle L.L.C.Inventors: Garret Noyons, Kyle Frake

Patent number: 9587900Abstract: An omni-directional recoil energy absorption mechanism has a slipping disk supported by a support plate carrying a weapon; and a cover plate covering the slipping disk and capturing it to create a sandwich structure of cover plate, slipping disk and support plate. Bolts act in conjunction with pressure springs to press the cover plate to the slipping disk toward the support plate and create friction forces in a plane of the slipping disk. Tension springs connect the slipping disk to the support plate under recoil force configured to return the slipping disk and the weapon to an initial position, in a center of the support and cover plates. The springs are preloaded to a pre-defined level to oppose, flexibly, the recoil forces in any vertical and radial directions, while absorbing the recoil energy by allowing the slipping of the slipping disk in between the cover and support plates.Type: GrantFiled: March 9, 2015Date of Patent: March 7, 2017Inventor: Yefim Kereth
