Abstract: A paddle is for corporal discipline. The paddle includes a handle, and a paddle portion having a base, and an elongate flat member extending from the base. The elongate flat member is to be used for striking a subject to be disciplined in the corporal discipline. The paddle also includes a hinge device comprising a first arm coupled to the handle, a second arm coupled to the base, a pivoting hinge coupled between the first arm and the second arm and configured to switch the paddle portion between a locked state where the paddle portion and the handle are substantially parallel and a folded state where the paddle portion and the handle freely move, and a settable feature. The settable feature selectively changes a threshold pivoting force of the pivoting hinge for causing the paddle portion to switch from the locked state to the folded state.

Abstract: This disclosure provides an apparatus, system, and method for thermal spraying a metal cladding on a substrate. The apparatus may include a housing having a first electrode and a second electrode disposed in the housing. The second electrode can be spaced apart from the first electrode. The apparatus includes a first contact tip removably attached to the first electrode and a second contact tip removably attached to the second electrode. The position of the first contact tip and second contact tip is configured to be selectively adjusted on the first electrode and the second electrode to provide a plurality of contact surfaces for a feedstock wire. The apparatus includes a nozzle between the first contact tip and the second contact tip. The first contact tip and the second contact tip are configured to contact and deflect a wire towards the nozzle.

Abstract: An earth boring bit has a bit body with a depending bearing pin, a cone rotatably mounted on the bearing pin, a seal gland between the cone and the bearing pin, and a seal assembly located in the seal gland. The seal assembly includes an annular metallic spring encircling the bearing pin. The spring has a geometric center line that extends in a circle around the bearing pin. The spring is elastically deformable in radial directions relative to the center line. An elastomeric layer is located on an exterior side of the spring and is biased by the spring against a surface of the seal gland.

Abstract: Apparatus for separating ash particles from a flue gas. The apparatus includes a screen that has a plurality of semi-elliptical cylinder surfaces. The semi-elliptical cylinder surfaces having holes through which said flue gas flows and through which the ash particles will not pass. The screen has a single layer for performing the separation in a manner such that the ash particles fall away from the screen and collect outside of the screen. A method of reducing velocity of a flue gas passing through screening apparatus for separating flue gas from ash particles. The method includes replacing a first screen of the screening apparatus with a second screen that has a plurality of semi-elliptical cylinder surfaces.
