Title: Passive enclosure dust control system
Inventor: SHELSTAD DELMER LEROY
IPC: B65G69/18
Filed: 2000-09-14
Abstract: A material handling transfer system which utilizes passive dust control methods for containing and controlling fugitive dust emissions generated during a transfer operation. The present system includes an enclosure containment structure which houses a specialty designed transfer chute for vectoring a stream of moving material from a first elevated transfer location to a second lower transfer location, the chute being constructed to reduce fugitive dust emissions at the second transfer location, an adjustable deflector mechanism for containing and funneling the bulk material onto the transfer chute structure, and a stilling zone positioned downstream from the second transfer location for impeding the propagation of any fugitive dust emissions through the exit area of the enclosure structure. The present enclosure structure is specifically designed to allow for recirculation of the induced air flow generated within the enclosure structure to both relieve any pressure build up formed therewithin, particularly, in the vicinity of the second transfer location, and to facilitate the agglomeration of dust particles within the enclosure. The present system is adaptable for use in a wide variety of different material handling transfer applications including applications which involve a belt-to-belt transfer operation, a belt-to-bin transfer operation, a bin-to-belt transfer operation, a crusher-to-belt transfer operation, and both in-line and angular transfer operations. The present system therefore provides a more cost effective and less complicated system for achieving a safe work environment in areas where fugitive dust emissions must be controlled and contained.

Title: Improved des and other cryptographic processes with leak minimization for smartcards and other cryptosystems
Inventor: KOCHER PAUL C
IPC: H04L9/06
Filed: 1999-06-03
Abstract: Methods and apparatuses are disclosed for improving DES and other cryptographic protocols against external monitoring attacks by reducing the amount (and signal-to-noise ratio) of useful information leaked during processing. An improved DES implementation of the invention instead uses two 56-bit keys (K1 and K2) and two 64-bit plaintext messages (M1 and M2), each associated with a permutation (i.e., K1P, K2P and M1P, M2P) such that K1P {Kl} XOR K2P {K2} equals the "standard" DES key K, and M1P {M1} XOR M2P {M2} equals the "standard" message. During operation of the device, the tables are preferably periodically updated, by introducing fresh entropy into the tables faster than information leaks out, so that attackers will not be able to obtain the table contents by analysis of measurements.      The technique is implementable in cryptographic smartcards, tamper resistant chips, and secure processing systems of all kinds.

IPC: H01S3/10
Filed: 1999-09-30
Abstract: A method and apparatus for detecting the presence of a specific concentration of gaseous species within a calibrated range in a gas sample is disclosed. The ILS gas detection system (10) of the present invention simply comprises an ILS  laser (12), a wavelength-selective optical element (52), and an optical detector (16). However, the potential or operational wavelength bandwidth of the ILS laser (12) is preferably entirely included within one of the absorption bands or regions assigned to the intracavity gaseous species being monitored. Thus, within the calibrated range, the presence of the gaseous species changes the output laser wavelength or output intensity at the specific wavelength of the ILS laser (12). Consequently, only the wavelength of the output or the output intensity at the specific wavelength of the ILS  laser (12) need be monitored in order to quantitatively determine the concentration of the absorbing gaseous species within a calibrated range when using the ILS method of the present invention.

IPC: B65D33/14
Filed: 2001-08-17
Abstract: A tissue disposal bag has a front wall and a back wall, and an elongate vertical centre area of the front wall for disposal of tissue into the bag. The front wall and the back wall of the bag are joined together to form a bag cavity between them. The opening is designed so that, upon application of a minimal force to a portion of the front wall where the opening is located, the front wall separates along the length of the opening, allowing for disposal of tissue through the opening and into the trash bag, which then retains its original shape. This allows for hygienic disposal of the tissue into the bag since the user does not have to close the bag manually.
