Abstract: An apparatus for removing the skin from an animal carcass. The apparatus comprises a cable, a two stage ball, and a skinner plate. The specially shaped two stage ball has a larger lobe and a relatively smaller lobe and a neck connecting the two lobes. To begin the skinning process, cuts are made in the deer's skin, or hide, and a portion of skin behind the deer's neck is pulled back. The skinner plate is placed on the raw side of the hide. The relatively smaller lobe of the two staged ball is pushed through an aperture in the skinner plate from the hair side of the hide. The cable is then tightened around the neck of the two stage ball, thereby cinching the hide to the two stage ball. A pulling force can then be applied on the cable and the skin peeled from the animal carcass.

Abstract: There is disclosed a system for linearizing an RF amplifier by the application of suitable load impedances to its 2nd, 3rd, and higher order output signals, thereby reducing output distortion products and improving performance. Intermodulation Distortion (IMD) reduction results from controlled termination of harmonic tuned filters produced by impedance selection and/or filter detuning. Preferably the apparatus comprises parallel band-pass filters including a filter passing the fundamental signals only; a filter passing 2nd harmonics; and a filter passing the 3rd harmonics. These, and optionally higher order filters, are employed for suppressing harmonic frequencies and reducing IMD. Preferably all filters have sufficient isolation to prevent serious interaction between filters. Therefore a selected mismatch provided at each of the harmonic output ports linearizes the amplifier's output.
