Abstract: A towel dispenser mounting system includes a mounting component; a sensor; and a dispenser. The sensor is directly attached to the wall and the dispenser is mounted to the wall through attachment of the mounting component to the wall. The dispenser contains a roll of material for dispensing towels, and the sensor is configured to detect a distance from the sensor to the roll, whereby an amount of towels to be dispensed may be calculated and/or an amount of towels already dispensed may be calculated. The sensor is located within a housing of the dispenser when the dispenser is attached to the mounting component; a back wall of the housing of the dispenser defines an opening through which the sensor is partially received. The mounting component also defines an opening through which the sensor extends. Mounting a dispenser to a wall to which a sensor is attached is also disclosed.

Abstract: A material sampling system for obtaining a plurality of substantially similar samples of granular material, such as grain or other crop material, from a load of granular material is provided. The system can include a sample extractor for obtaining a sample portion of granular material, a sample divider operative to divide the sample portion of granular material into a plurality of smaller samples of granular material in a plurality of sample containers and a sample transfer conduit for transferring the sample of granular material from the sample extractor to the sample divider. The sample portions can be taken at regular sample time intervals throughout the entire load of granular material to get an accurate representation of the granular material and information about the samples in the sample containers can be obtained by the system while it is obtaining the samples and this information stored for later use and display.

Abstract: A spectroscopic sample analysis apparatus includes an actively controlled heat exchanger in serial fluid communication with a spectroscopic analyzer, and a controller communicably coupled to the heat exchanger. The heat exchanger is disposed downstream of a fluid handler in the form of a stream selection unit/stream switching unit (SSU), a solvent/standard recirculation unit (SRU), and/or an auto-sampling unit (ASU). The SSU selectively couples individual stream inputs to an output port. The SRU includes a solvent/standard reservoir, and selectively couples output ports to the heat exchanger, and returns the solvent/standard sample to the reservoirs. The ASU includes a sample reservoir having a sample transfer pathway with a plurality of orifices disposed at spaced locations along a length thereof. The controller selectively actuates the fluid handler, enabling sample to flow there through to the heat exchanger, and actuates the heat exchanger to maintain the sample at a predetermined temperature.

Abstract: A method and apparatus is provided for determining concentration of components in a liquid hydrocarbon mixture including hydrocarbons and water flowing through an alkylation process. A fluid flow path conveys the liquid continuously from the alkylation process through a first instrument configured for measuring a property of the liquid mixture, and having responsivities to concentration of the components, which are independent of the concentration of the water. A temperature detector generates temperature data for the liquid, and a second instrument measures another property of the liquid mixture. The instruments have mutually distinct responsivities to concentrations of the components.

Abstract: A method and apparatus is provided for off-line concentration determination of components liquid hydrocarbon mixtures such as crude or heavy oil. A sampling unit continuously delivers a sample volume to a fluid flow path while a temperature control module maintains the sample at a predetermined setpoint temperature. A homogenization module helps prevent sample stratification while a flow control module maintain a constant sample flow rate. A spectrometer is communicably coupled to an optical transmission cell to transmit and receive radiation. The transmission cell includes collection optics to capture and aggregate non-collimated radiation emerging from the cell, for transmission to the spectrometer. The spectrometer measures sample spectra at a predetermined rate of flow of the sample volume through the transmission cell. A processor is configured to capture and use the spectra in combination with a model of spectra for the hydrocarbon mixture.

Abstract: A depilatory cream remover, which may include a head, a shaft and a handgrip. The head may be substantially perpendicular relative to the shaft. The head may include a length long enough to accumulate the depilatory cream while the depilatory cream remover is in use. The head may further include rounded corners to prevent irritation.

Abstract: A method and apparatus is provided for determining concentration of components in a liquid hydrocarbon mixture including hydrocarbons and water flowing through an alkylation process. A fluid flow path conveys the liquid continuously from the alkylation process through a first instrument configured for measuring a property of the liquid mixture, and having responsivities to concentration of the components, which are independent of the concentration of the water. A temperature detector generates temperature data for the liquid, and a second instrument measures another property of the liquid mixture. The instruments have mutually distinct responsivities to concentrations of the components.

Abstract: Closed-loop control of a hydrocarbon process is provided by an analyzer including an instrument configured for measuring a property of the liquid mixture, and having responsivities to concentrations of one of the components, independent of concentrations of others of the components. A temperature detector generates temperature data for the liquid mixture, and a processor captures data generated by the temperature detector and the instrument, and uses the data in combination with a model of responsivities to various concentrations of the components at various temperatures, to determine a temperature compensated concentration of the components while the liquid mixture flows continuously through the analyzer. A process control module including a process model of the hydrocarbon process, is coupled to the analyzer and is couplable to the hydrocarbon process, to receive the temperature compensated concentration and to generate at least one output configured to affect operation of the hydrocarbon process.
