Abstract: A flange includes a flange body and a scallop feature. The flange body is annularly disposed about a longitudinal axis. The flange body includes a first radial side and a second radial side radially opposite the first radial side. The flange body defines a first fastener hole and a circumferentially adjacent second fastener hole. Each of the first fastener hole and the second fastener hole are formed through the flange body. The scallop feature is formed through the flange body and disposed circumferentially between the first and second fastener holes. The scallop feature extends radially from the first radial side through at least a portion of the flange body. The scallop feature includes a first side and a second side, parallel to the first side.

Abstract: Integrally bladed rotors (IBRs) are described. The IBRs include a central hub, an outer rim defining an outer circumference of the central hub, the outer rim defining a plurality of platforms, a plurality of circumferentially distributed blades, wherein a blade extends from each of the plurality of platforms, a rotor slot arranged between two adjacent blades, wherein the rotor slot is defined by a cut within the outer rim, and a rotor slot insert installed within the rotor slot, the rotor slot insert sized and shaped to fit within the rotor slot and prevent air leakage from a first side of the central hub to a second side of the central hub through the rotor slot during operation of the integrally bladed rotor.

Abstract: A system and method for generating and sending marketing emails. The marketing emails are generated at an API server, where the emails promote a product and/or service, and where the API server is owned and/or controlled by a marketing firm. A user of a computer owned by a sales company logs onto the API server, where the computer operates through a company server, and where the API server formats the marketing emails to include information identifying the sales company. The user of the computer requests that the emails be sent from the API server to the computer, and the emails are sent from the computer to a potential customer using the company server. The request for the emails can be made by pulling or pushing or be manually requested by the user, and the emails can be sent from the computer to the customer automatically or manually by the user.

Abstract: A motorcycle with an improved steering mechanism is provided. The motorcycle is provided with a swing arm which is moveably attached to a tracking mechanism. The tracking mechanism is an arcuate track which is attached directly to the frame or engine of the motorcycle. When the front wheel is steered about its steering axis, the swing arm moves along the arc of the arcuate tracking mechanism.

Abstract: A head band for retaining eyeglasses in place comprising a elastomeric, fabric covered stretch band made adjustable by sliding the bows or temple pieces of eyeglasses into tubular members formed from the end portions of a flat band. The tubular members are an integral part of the band so the assembly is a unitary piece.
