Abstract: Peroxyformic acid compositions for removal of biofilm growth and other contaminants and impurities from industrial processing hard surfaces are disclosed. In particular, peroxyformic acid compositions may be dosed on site and/or generated in situ for the reduction and prevention of biofilms on the hard surfaces. Methods of employing the peroxyformic acid compositions for removal of biofilm growth and other impurities such as aldehydes and alcohols from industrial CO2 effluent are also disclosed which beneficially provide ambient biofilm control and break down more rapidly than other peracids, allowing for extended runs between CIP cleaning, including a reduction and/or elimination of cleaning of the scrubbers and other industrial surfaces.

Abstract: A method of washing aggregate material, the method comprising: receiving aggregate material in a tank; receiving water in said tank; by at least a rear wall of said tank, retaining said aggregate material and water in a rearward portion of said tank and preventing said water and aggregate material from overflowing said rear wall; agitating said aggregate material and water to form a slurry; advancing said slurry to a tank outlet in a forward portion of said tank; depositing said slurry through said tank outlet; receiving said slurry on a vibrating screen; allowing an undersize portion of said slurry to fall through said vibrating screen; pumping at least a fraction of said undersize portion to a hydrocyclone; by said hydrocyclone, separating said fraction of said undersize portion into an underflow fraction and an overflow fraction; receiving said underflow fraction on said vibrating screen; and passing product from said vibrating screen.

Abstract: The present disclosure provides a balloon dilation catheter that includes a handle (102), a substantially rigid inner guide member (108) coupled to the handle, a shaft (118) arranged over the inner guide member, a balloon (120) coupled to the inner guide member, and a polymer ball tip (122) positioned at a distal end of the balloon. To treat a sinus drainage pathway of a subject using the balloon dilation catheter, the substantially rigid inner guide member is positioned into the drainage pathway of the sinus of the subject via a nasal passageway. The balloon is then inflated to expand or otherwise remodel the drainage pathway.

Abstract: Methods and systems for managing register content is described. A register content management module receives an identity of the retail location register, identifies a geographic location associated with the retail location register, identifies a time for which the updated register content is requested, generates a new register content, and sends the new register content to the retail location register independently from sending an application update to the retail location register.

Abstract: A computer-implementable method may include booting an information handling system from a boot image stored on a non-transitory computer-readable storage medium, prompting, by the boot image, for a password for an encrypted volume of the non-transitory computer-readable storage medium, loading, by the boot image, a kernel stored within the encrypted volume, passing, by the boot image, the password to a specialized module stored within the encrypted volume, decrypting, by the specialized module, the encrypted volume using the password, and causing, by the specialized module, execution of an operating system installation image stored within the encrypted volume to install the operating system on the information handling system.
