Abstract: The present invention is a method and apparatus for gelling liquid propane and other liquefied gasses. The apparatus includes a temperature controlled churn mixer, vacuum pump, liquefied gas transfer tank, and means for measuring amount of material entering the mixer. The method uses gelling agents such as silicon dioxide, clay, carbon, or organic or inorganic polymers, as well as dopants such as titanium, aluminum, and boron powders. The apparatus and method are particularly useful for the production of high quality rocket fuels and propellants.

Abstract: Improvements to paper web material dispensers, particularly two roll tissue dispensers. A dispenser according to the invention is able to prevent access to a second or reserve roll of tissue until a first or dispensing roll is entirely or substantially depleted. As a result, the tissue of the first roll must be used up, or substantially used up, before tissue from the second roll can be used, thereby avoiding tissue waste. The dispenser of the invention can be used with reduced core tissue rolls, where each roll has first and second core sections that are spaced apart from each other to form a gap between facing ends thereof so that the total length of the core sections is less than the width of the tissue wound onto the core sections. The dispenser of the invention thus encourages the use of reduced core tissue rolls, which results in a reduction of waste resulting from used tissue cores.

Abstract: The invention contemplates a method for recognition of proteins and other biological molecules by imaging morphology, size and distribution of crystalline and amorphous dry residues in droplets (further referred to as “crystallization pattern”) containing predetermined amount of certain crystal-forming organic compounds (reporters) to which protein to be analyzed is added. It has been shown that changes in the crystallization patterns of a number of amino-acids can be used as a “signature” of a protein added. It was also found that both the character of changer in the crystallization patter and the fact of such changes can be used as recognition elements in analysis of protein molecules.

Abstract: A hands-free paper towel dispenser including a housing with a front cover that is pivotable between open and closed positions. A sensing mechanism is disposed entirely within the interior space of the cabinet at a location adjacent to the front cover and is oriented toward the front cover of the cabinet to permit detecting of an object adjacent the front cover without the object contacting the front cover. At least a portion of the sensing mechanism is accessible when the front cover is at the open position. A dispensing mechanism is disposed within the housing for dispensing a length of towel, with the dispensing mechanism including a drive roller and a motor in driving engagement with the drive roller. The dispenser also includes an electric power source for powering operation of the dispenser.

Abstract: Improvements to a paper web material dispenser, for example a roll tissue dispenser or a roll paper towel dispenser, that has a user actuation mechanism for rotating a dispensing mechanism of the dispenser. The dispenser is designed to prevent excessive force that is applied to the user actuation mechanism from causing damage to components of the dispenser connected to the user actuation mechanism. A torque limiting mechanism is used to limit the torque that is applied to the dispensing mechanism of the dispenser when a user applies an excessive force to the user actuation mechanism. The torque applied to the dispensing mechanism is kept below a level that would be sufficient to cause damage to the dispensing mechanism or portions thereof.

Abstract: A hands-free towel dispenser comprising a housing with a roll of towels inside an interior, a sensor for detecting the presence of an object and generating a signal, a motor driving a dispensing means for dispensing a desired length of towel, a control circuit for receiving the signal from the sensing means and controlling supply of power to the motor driving the dispensing mechanism, and a battery. The control circuit is adapted to sample back EMF generated by the motor while the dispensing means is dispensing the towel and to determine based on the sampled back EMF a calculated run time for the operation of the motor to dispense the desired length of towel. A method of dispensing a desired length of towel wherein a sensor generates a signal when the presence of an object is sensed. A control circuit receives the signal from the sensor and supplies power from a battery to a motor to drive a dispensing means to dispense a desired length of towel from the roll.

Abstract: In one embodiment, this invention analyzes demographic data that is associated with a specific street address when presented as an address change on an existing account or an address included on a new account application when that address is different from the reference address (e.g., a credit bureau type header data). The old or reference address and the new address, the new account application address or fulfillment address demographic attributes are gathered, analyzed, compared for divergence and scaled to reflect the relative fraud risk.
