Abstract: A toothpaste dispensing pen style toothbrush including a toothbrush head assembly, a housing assembly, and an electrical assembly is disclosed. These assemblies in conjunction with one another provide a simple solution to brushing your teeth. The housing assembly includes toothpaste stored therein. A screw rod is longitudinally mounted within the housing assembly. At a bottom portion of the screw rod is a screw cup. The screw cup travels the length of the screw rod when a button is pressed to actuate a battery powered motor that spins the screw rod. The screw cup then pushes the toothpaste out of the housing and into the toothbrush head assembly along a channel. The channel ends at an outlet on a toothbrush head. Thereby dispensing toothpaste onto toothbrush bristles. A user can place a cap over the toothbrush head assembly that resembles a pen cap.

Abstract: An apparatus and method for collection of particulate matter includes a plenum chamber formed in an funnel or a frustum configuration that discharges into a distribution chute assembly. The distribution chute assembly includes a number of individual chutes, each equipped with a circular collar or collar groove at the outlet which facilitates the attachment of the cylindrical dust collection sacks. The plenum chamber, distribution chute assembly, and individual dust collection sacks are carried by a frame assembly.

Abstract: A well-logging tool for a geological formation includes a housing to be positioned in a borehole and an antenna assembly carried by the housing. The antenna assembly includes an antenna housing having a recess therein. A dielectric material layer comprises a basalt fiber composite and is within the recess. At least one antenna coil is supported by the dielectric material layer. An electrical connector is coupled to the at least one antenna coil. Resistivity processing circuitry is coupled to the electrical connector to determine an electrical resistivity of the geological formation based on the at least one antenna coil.
