Title: High-moisture raisins for use in food processing
Inventor: BRUNO RICHARD C
IPC: A23B7/148
Filed: 1993-12-16
Abstract: Raisins are preconditioned for use in food preparations where a high moisture content is required, by exposing the raisins to heated water or steam to elevate the temperature 130 °F (54°C) or above, followed by reducing the oxygen content of the atmosphere surrounding the raisins and sealing them in moisture-tight and air-tight while still hot, and storing the raisins in this condition for a sufficient period of time destroy substantially all spoilage microorganisms present. If held for at least twelve hours and the temperature is at least about 120 °F (49°C), sugaring is prevented as well. The result is a highly uniform product with pleasing appearance and texture suitable for direct use in baking or other food preparations.

Title: Chlorine dioxide generation for a zero discharge pulp mill
Inventor: LINDBERG HANS G
IPC: C01B11/02
Filed: 1993-11-16
Abstract: Chlorine dioxide for a cellulose pulp mill bleach plant is produced by concentrating (evaporating) liquid effiuents from the bleach plant to a concentration level high enough for incineration, incinerating the concentrated effluents to produce an ash, chemically reacting at least a part of the ash to produce chlorate, and using the chlorate in the manufacture of chlorine dioxide. The ash is purified to produce sodium chloride and the sodium chloride is reacted with oxygen and external energy to produce sodium chlorate. The chlorate is then used in the manufacture of chlorine dioxide. Sulfates produced are used to manufacture acid and/or caustic, and heavy metal hydroxides are disposed of. A part of the ash may be used directly in chlorine dioxide manufacture. At least some of the salt from chlorate manufacture may be fed to the chemical recovery loop, including a recovery boiler, in the pulp mill. Evaporated gases may be returned to the pulp mill and bleach plant.

Abstract: A safety system is provided for mounting a pressure vessel system such as a natural gas tank to a support structure such as on a vehicle. The pressure vessel system includes a shell having an aperture alignable with an aperture in the support structure. A fastener extends through the aligned apertures and includes a shear section located at an interface between the shell and the support structure to provide a first safety measure defining the point of separation of the vessel from the sup-port structure due to sudden impact. A tether cable is interconnected between the pressure vessel system and the support structure. The tether cable has at least a minimum amount of slack therein to provide a second, sequential safety measure to restrain free travel of the pressure vessel system should the shearable fastener break. A camming surface is provided between the pressure vessel system and the support structure for directing the vessel system away from a forward direction of travel, to provide a third, sequential safety measure in the event that the vessel system breaks away from both the shearable fastener and the tether cable. A safety pressure vessel system incorporates a plurality of inner pressure tanks within the shell, the tanks and shell being fabricated of filament composite material. A shock absorbing foam filler is provided within the outer shell separating the inner tanks from each other and the inner tanks from the outer shell.

Title: Cosmetic dispenser with cam locking feature
Inventor: HOLLOWAY THOMAS F
IPC: A45D40/06
Filed: 1995-08-22
Abstract: A cosmetic preparation dispenser is provided that has a helical cam track with a horizontal step at its lower  end  and  a  longitudinal  innerbody  track  that terminates adjacent the horizontal step.  A cam follower lug of an elevator cup will track into and be trapped by and between the horizontal step and the lower end of the longitudinal track.
