Publication number: 20230349138Abstract: A hydraulic propulsion system for disposing of human waste. The system includes a toilet having a bowl, and a base below the bowl. The base is secured to the chassis of a vehicle, or to a remote sanitation facility. The system also comprises a hydraulic flushing mechanism associated with the toilet, and a fluid receiving chamber that receives water and human waste when the flushing mechanism is actuated. The human waste is directed through a sewage ejection pipe and into a black-water tank or a municipal sewer system. The human waste propulsion system further comprises a pneumatic line. The pneumatic line is in fluid communication with the fluid receiving chamber proximate the bowl. The pneumatic line receives compressed air which is delivered when the hydraulic flushing mechanism is actuated. Additionally, the human waste propulsion system has a controller.Type: ApplicationFiled: April 19, 2023Publication date: November 2, 2023Inventor: Mark G. Townes

Patent number: 5544090Abstract: An apparatus and method for monitoring and processing a web of textile materials which includes a plurality of entities including fibers, neps, seed coat fragments and trash. The web is monitored, preferably by an imaging unit, to produce a monitor signal. A computer receives the monitor signal and locates the position of entities of interest and controls a web processor in accordance with the location of the entities. Preferably, the web processor includes ejectors for ejecting entities from the web under the control of the computer. In one embodiment, the web is formed by a sampler and forming apparatus which removes a sample of fibers from a supply and reconfigures it into a desired configuration, such as a web, for being monitored.Type: GrantFiled: November 9, 1994Date of Patent: August 6, 1996Assignee: Zellweger Uster, Inc.Inventors: Frederick M. Shofner, Joseph C. Baldwin, Gordon F. Williams, Mark G. Townes

Patent number: 5537868Abstract: Conditioned gas flows are applied at various critical locations in instruments and apparatus for testing and processing textile fibers, such as cotton. In the context of test instruments, a standard test zone environment (which becomes part of the test record) is effected by the introduction of controlled conditioned gas flows directly into a testing zone, including into testing instruments themselves. In the context of processing apparatus, direct control of processing performance parameters is effected by "controlling parameters", which are in turn effected by the application of conditioned gas flows. A plurality of "performance parameters", which may be in conflict with each other, may be controlled in accordance with a predetermined compromise control strategy, carried out by feedback or feedforward control systems implementing modern statistical control approaches.Type: GrantFiled: October 25, 1994Date of Patent: July 23, 1996Assignee: Zellweger Uster, Inc.Inventors: Frederick M. Shofner, Mark G. Townes

Patent number: 5491876Abstract: Disclosed are various needle-based devices for individualizing single fibers and other entities from a fibrous mass, particularly for testing purposes. In one embodiment, an accelerated pin drafting machine has a plurality of combing elements which sequentially pierce a fiber mat and move within a drafting zone with increasing distance between adjacent combing elements. The accelerated pin drafting machine in turn feeds a fiber individualizer. In another embodiment, a comb-like needle sampler is provided which moves past a perforated plate such that portions of fibrous material protruding through the perforations are loaded onto the needle sampler. An elastomer clamping feedroll moves against the needles to clamp the sample, and then rotates to gradually feed fibers from the sampler. As an alternative to the elastomer clamping feedroll, a clamping block presses against the needles, and the needles are slowly retracted to gradually release fibers.Type: GrantFiled: September 29, 1994Date of Patent: February 20, 1996Assignee: Zellweger Uster, Inc.Inventors: Frederick M. Shofner, Mark G. Townes, Gordon F. Williams

Patent number: 5321496Abstract: An apparatus for monitoring trash in a sample of trash particles and fibers includes scales for determining the weight of the sample which is transmitted to a computer. The sample is presented to a sensing volume and an optical sensor produces an output signal corresponding at least to the presence of the trash particle in the sensing volume. In one embodiment, the output signal is the waveform corresponding to light extinction caused by the presence of the particle in the sensing volume. In a second embodiment, image analysis of trash particles in a sensing volume provide output signals corresponding to the size, shape or composition of the particles. The computer receives the weight data and the output signal from the optical sensor and produces output data in the form of a count of at least a portion of the trash particles per unit weight of sample.Type: GrantFiled: September 19, 1991Date of Patent: June 14, 1994Assignee: Zellweger Uster, Inc.Inventors: Frederick M.

Patent number: 5203206Abstract: An apparatus for testing fibers includes a single fiber preparation and separation device for separating fibers from a sample of multiple fibers and producing an output of single fibers. A fiber transport means, preferably an air conduit, receives the single fibers and transports them to a removed location where at least one fiber is sampled from the transport means. In the preferred embodiment, the sampler is a hook that is inserted into, and removed from, an air conduit to hook and remove single fibers carried in a stream of air inside the air conduit. A testing apparatus associated with the sampler then determines at least one characteristic of the sampled fiber, such as strength, tension as a function of elongation, or cross sectional characteristics.Type: GrantFiled: September 23, 1992Date of Patent: April 20, 1993Assignee: Zellweger Uster, Inc.Inventors: Fred M.

Patent number: 5167150Abstract: A fiber testing apparatus includes two support members for holding a fiber and a positioning mechanism to facilitate placement of the fiber into engagement with the support members. A translation apparatus moves the two support members apart while a monitor records at least one characteristic of the fiber as it is tensioned. In one embodiment, the two support members are first and second clamps and the positioning apparatus includes first and second suctions oriented to draw the fiber in opposite directions and place the fiber in a substantially linear configuration adjacent to both clamps. In another embodiment, a hook and clamp configuration is utilized, and in yet another embodiment a vacuum groove is employed to facilitate positioning of the fiber.Type: GrantFiled: June 27, 1991Date of Patent: December 1, 1992Assignee: Zellweger Uster, Inc.Inventors: Frederick M.

Patent number: 5138879Abstract: A method for producing multiple fiber data from a plurality of single fiber tests. A plurality of individual fibers are subjected to tension tests such that the individual fibers are elongated tensioned and broken while characteristics of the fiber are monitored. Multiple fiber data are obtained by testing a number of fibers from a sample and superimposing the graphical representation of tensile characteristics of the individual fibers upon one another to obtain a composite representation which constitutes multiple fiber data. Characteristics of individual fibers which may be combined to obtain a composite representation constituting multiple fiber data include such characteristics as tension, elongation and cross-sectional characteristics of the fiber.Type: GrantFiled: August 23, 1991Date of Patent: August 18, 1992Assignee: Zellweger Uster, Inc.Inventors: Frederick M. Shofner, Youe-T Chu, Christopher K. Shofner, Mark G. Townes
