Abstract: A bead crimping tool for crimping a bead element and method for use, wherein the tool includes a base handle, a crush plate member, a pair of opposed pincer members, an actuator handle, and a crush arm member. The bead element is placed on the crush plate and preferably secured in place by the crush arm. Crimping the bead includes squeezing of the actuator handle. During a first portion of such actuation, a cam portion of the actuator handle cases the pincer members to impart a lateral compressive force to a lateral portion of the bead element sufficient to collapse the bead element in a lateral direction. During a subsequent second portion of the single actuation cycle, the crush arm is caused to impart a longitudinal compressive force about a top portion of the bead element sufficient to compress the collapsed bead element in a longitudinal direction.

Abstract: A spherical outer diameter tapered roller bearing pillow block system (100) for supporting the rotating main shaft of a wind turbine. The bearing system is configured with a unitized construction and factory set preload bearing settings to facilitate installation and setup. A spherical outer diameter surface (114) is formed on the outer race (116) of a tapered roller bearing assembly disposed about the rotating main shaft of the wind turbine. The bearing assembly is secured to a stationary support structure of the wind turbine through a pillow block housing assembly (102) providing a matching spherical housing seat (112) to form a ball and socket interface between the tapered roller bearing assembly (118) and the pillow block housing assembly (102). The ball and socket interface accommodates static and dynamic misalignments between the wind turbine main shaft and the supporting structure, while the bearing assembly (118) accommodates radial and axial loads.

Abstract: The present disclosure provides for systems and method for producing hybrid seed. In various embodiments, the disclosure provides a system for the high-throughput, nondestructive sampling of seeds. In another embodiment, a high-throughput, nondestructive method for producing hybrid seeds comprises removing a sample from a plurality of seeds in the population while preserving the germination viability of the seed and analyzing the sample for the presence or absence of one or more genetic markers indicative of a male-sterile gene.

Abstract: Jamb connectors for finishing a penetration in concrete or masonry construction, the jamb connectors coupling a first jamb with a second jamb that is adjacent to the first jamb and having a first portion with two segments lying substantially in a same plane and positioned at a predetermined angle from each other, each first portion segment being configured for coupling with an associated surface portion of an associated one of the first and second jambs, and a second portion having two segments that are each coupled to corresponding segments of the first portion, each second portion lying at an angle equal to the predetermined angle from the other second portion and second portion being configured for positioning about the intermediate portions of one of the first and second jambs.

Abstract: A message alert broadcast broker and method for providing a broadcast message to a plurality of user devices located within a broadcast target area including a broadcast service bureau receiving from one of a plurality of coupled broadcast agent access systems providing a broadcast request from an originating broadcast agent associated one broadcast agent access system, the broadcast request including a broadcast agent identification, the geographically defined broadcast target area, a broadcast message, and a broadcast channel code, the broadcast service bureau verifying the broadcast request as a function of the broadcast agent identification including the authority of the originating broadcast agent to send the broadcast message to the broadcast target area using the broadcast channel code, the broadcast service bureau processing the verified broadcast request for transmission to one or more mobile telephone networks providing service to at least a portion of the broadcast target area of the broadcast requ

Abstract: A control assembly for use in a feed delivery assembly comprises a housing having an inlet, an outlet, and a chamber between said inlet and outlet. The chamber is opened in a plane parallel, but radially offset from, an axis of the inlet and outlet. A tube member is removably receivable in the chamber. The removable tube member includes a tube having a length sufficient to span a distance between the inlet and outlet tubes. At least one infrared emitter and at least one infrared receiver are mounted on the tube member tube and are positioned to be opposed to each other such that the receiver will receive and detect light from the emitter. The emitter and receiver are operatively connected to a controller. The controller emits a signal when it is determined that the light from the emitter to the receiver is interrupted.
