摘要： A portable toilet is provided with a bowl having an outlet port in its bottom, this being closed by a yoke shaped, pivotal valve member movable between a first position in which it closes the outlet port and a second position in which it uncovers the port. An actuation member moves relative to the valve member and cooperating cam surfaces on the valve member and actuation member urge the valve member upwardly to seal the outlet port upon such relative movement.

摘要： A capacitive sensor includes one or more chambers through which a material can flow. Two conductors are located to partially surround the flow chamber so that the material flows between the conductors. Where more than one chamber is used, additional conductors are provided. A measurement circuit connected to the conductors provides an output corresponding to a difference between test and reference frequencies. A display indicates the measured capacitance as a continuous-scale, proportional representation or a binary representation. The sensor system can measure volume charge density of a fluid or parameters responsive to changes in volume charge density, such as flow velocity.

摘要： A double-acting, weight distributing trailer hitch includes a drawbar assembly and a hitchhead assembly. The drawbar assembly is releasably connected to a tow vehicle and includes a first coupling component at its rearward end. The hitchhead assembly includes a second coupling component and a rearwardly extending drawbar extension, which are pivotably connected along substantially vertical axis by a yoke. The drawbar extension is pivotally connected to the yoke by a cam. The drawbar extension is also mounted pivotably to the hitch ball along a first horizontal axis that is transverse to the direction of travel. A rearward portion of the drawbar extension is pivotably interconnected to the trailer along a second horizontal axis, which is parallel to the first horizontal axis and located behind the hitch ball. This creates an overlap between the forward end of the trailer and the drawbar extension. A spring assembly dampens pivoting of the drawbar extension about the horizontal axes and thereby dampens hinging movement between the tow vehicle and trailer. The cam is operated to adjust the hitchhead so that a predetermined angle is imparted to the drawbar. The coupled tow vehicle and trailer operate essentially as a unified beam and resist relative hinging movement and resulting instability while driving along the highway. The spring also allows the tow vehicle and trailer to stably negotiate dips and bumps in the roadway at relatively low speeds.

摘要： A capacitive sensor is shielded against external electric fields to maximize measurement accuracy. The sensor may include two coaxial, tubular conductors with a chamber between them into which a material sample to be measured is introduced. A measurement circuit connected to the sensor may include a reference oscillator that oscillates at a constant frequency and a test oscillator that oscillates at a frequency responsive to sensor capacitance. The circuit may display a value responsive to the difference between the test and reference frequencies. The circuit may also reverse the polarity of the signal applied to the sensor to minimize charge buildup, a phase-locked loop frequency measuring circuit, a temperature compensating circuit, and a non-linearity compensating circuit. The indicating circuit that displays a representation of the measured capacitance may display a continuous-scale or proportional representation or may display a binary or “go-nogo” representation. An alternative sensor of the system includes coaxial, finned inner and outer conductors that intermesh to maximize capacitive surface area. Another alternative sensor includes two parallel, plate-like conductors. The sensor system may be used to measure volume charge density of a fluid or parameters responsive to changes in volume charge density, such as flow velocity.

摘要： A double-acting, reduced tongue weight trailer hitch includes a drawbar assembly and a hitchhead assembly. The drawbar assembly is releasably connected to the tow vehicle and includes a first coupling component at its rearward end. The hitchhead assembly includes a second coupling component and a drawbar extension pivotally connected to the second coupling component along a vertical axis. The drawbar extension is pivotally interconnected to the hitch ball along a first horizontal axis that is transverse to the direction of travel. A rearward portion of the drawbar extension is pivotally interconnected to the trailer along a second horizontal axis, which is parallel to the first horizontal axis and located behind the hitch ball. This creates an overlap between the forward end of the trailer and the drawbar extension. A spring assembly dampens upward and downward movement of the trailer relative to the drawbar extension. The coupled tow vehicle and trailer operate essentially as a unified beam and resist relative hinging movement and resulting instability while driving along the highway. The spring also allows the tow vehicle and trailer to stably negotiate dips and bumps in the roadway at relatively low speeds.
