Patent number: 7665490Abstract: A loader device for a hopper-fed processing machine has a top plate pivotally secured to a bottom plate. The plates are attached between the processing equipment throat and the material hopper, or vacuum receiver/reservoir. As the top plate pivots upon the other, ports that extend through the plates control the flow of material from the hopper into the throat of the machine. The pivot design, a purge funnel, and a drain tube are additional features that save time, labor, and make switching of processing material quick and convenient without the use of tools.Type: GrantFiled: March 6, 2006Date of Patent: February 23, 2010Assignee: Empirical Design, LLCInventor: Robert D. Elliott

Patent number: 7199571Abstract: A probe apparatus disclosed for use in a separable connector includes an insulating body and spaced apart first and second electrical conductors in contact with the insulating body. The first and second electrical conductors have adjacent surfaces configured such that when an electrical potential is applied between the conductors, an electric field is formed between the conductors. The insulating body has an opening positioned between the conductors and adapted to receive a sensor such that a portion of the sensor is subjected to the electric field. A separable electrical connector system is described including the probe apparatus, as is a voltage sensing system including the probe apparatus and a voltage sensor positioned within the opening of the insulating body.Type: GrantFiled: July 27, 2004Date of Patent: April 3, 2007Assignee: Optisense Network, Inc.Inventors: Leonard A.
