Abstract: A process for expanding tobacco is provided which employs liquid carbon dioxide as the expansion agent. Tobacco is contacted with liquid carbon dioxide to thoroughly impregnate the tobacco with the liquid carbon dioxide. The carbon dioxide impregnated tobacco is maintained at a temperature no lower than -2 DEG  C. and under conditions of temperature and elevated pressure such that all or substantially all of the carbon dioxide which is in contact with the tobacco is in liquid form. After the impregnation has been completed, any excess liquid carbon dioxide which may be present with the tobacco may be removed from the tobacco. The elevated pressure is then reduced in order to convert the liquid carbon dioxide to solid carbon dioxide within the tobacco structure. The resulting solid carbon dioxide-containing tobacco is then subjected to conditions of temperature and pressure, preferably by rapid heating at atmospheric pressure, such that the solid carbon dioxide is vaporized and the tobacco is thereby expanded. Apparatus for carrying out the above described process is also provided.

Abstract: A method for brightening a natural calcitic ore by removal of discoloring contaminants. The ore is crushed and formed into an aqueous slurry, which slurry is then coarse-milled to produce a product wherein no more than 1 percent of the particulate matter is +325 mesh. This coarse-milled product is then subjected to a further, wet-milling step, to alter the particulate such that at least 70 percent of the particles are less than 2 microns, thereby liberating substantial quantities of the discoloring contaminants. The liberated impurities are thereupon separated from the slurry by flotation and/or by subjecting the slurry to a high intensity magnetic field.

Abstract: A hydrostatic transmission comprising a closed loop system incorporating a hydraulic pump and a hydraulic motor driven by the pump has an accelerator for the motor drive shaft which sets the maximum delivery pressure of the pump, and control means which acts to vary the relative volume displacement of the pump and the motor to maintain the pump delivery pressure at the maximum value determined by the setting of the accelerator. Thus, the closed loop system maintains a substantially constant maximum pressure throughout the flow range, and since the output torque of the motor drive shaft is proportional to this system pressure a true acceleration control is achieved. The relative value displacement of the pump and the motor may be influenced by the low pressure of delivery of the pump on overrun of the motor shaft and by a spring loaded braking valve adjustable by a pedal control to provide for braking of the motor drive shaft.

Abstract: METHOD AND APPARATUS FOR DETERMINING THE LOCATION OF THE CHIP LEVEL IN A PULPING DIGESTER A pulping digester contains a liquid digesting medium and wood chips dispersed in the medium.  The level of the wood chips in the digester is normally below the top of the digester.  As chips and digesting medium are fed to the digester and as pulp and digesting medium are withdrawn from the digester, the chip level will vary dependent upon the net addition of chips and withdrawal of pulp.  The variable location of the chip level, or chip height, is determined by positioning a temperature sensing means in the upper portion of the digester above the normally desired chip level.  The temperature sensed by the sensing means is displayed to and monitored by the digester operator.  As the chip level rises toward the temperature sensor, the sensed temperature will fall until the chip level rises above the location of the temperature sensor, after which the sensed temperature will rapidly increase as the chip level continues to rise above the location of the sensing means.  The inverse relationship is true as the chip level falls, providing a characteristic curve of temperature versus chip level from which the chip height can be determined.

Abstract: An array camera used to scan elongated workpieces moving through a measuring zone transversely to their lengths has its photoresponsive detector elements aligned lengthwise of the workpieces, with optical axes of the elements lying in a common plane intersecting the measuring zone. Each element "sees" only a small (e.g., 8x8 mm) pixel. Radiation sources are located at opposite sides of said plane and emit radiation towards the measuring zone to be reflected to the elements from workpieces. During each of a succession of short measuring cycles (e.g., 4 millisecond duration) each element is exposed successively to radiation originating from each radiation source to the exclusion of the other, to thus produce an A output and a B output during each cycle, and is also exposed to substantially low level radiation to produce an R output. For each cycle, the R output of at least certain elements is subtracted from the A and the B outputs of the same elements for the same cycle, to produce  DELTA A and  DELTA B difference signals. Timing is such that  DELTA A and DELTA B signals for the same element and cycle originate from one and the same small surface area on the workpiece, and therefore inclination of that surface area is ascertainable as a function of the  DELTA A and  DELTA B values. During a fourth interval in each cycle, certain elements detect radiation from a laser that has its beam in said plane and oblique to the workpiece surface, and such elements then produce an L output. From the particular elements that produce L outputs, local thickness of the workpiece is ascertainable.
