Abstract:
The shive analyzer is formed by a closed chamber having a conical outlet with a spherical segment forming a plug for the outlet and defining an annular slot. The relative position of the plug and the conical outlet are accurately adjustable and these elements are mounted for relative movement to open the slot from a preset adjusted position. The analyzer is adapted for continuous operation and is fed by a positive displacement pump that pumps pulp at a preset constant rate. A device senses a determined increase in the pressure and opens the slot by relative movement of the spherical segment relative to the conical outlet. Another device counts the number of times the predetermined pressure increase is reached within a preset period of time to provide an indication of the number of shives in the pulp.
Abstract:
An efficient electrostatic spray installation that can spray a wide range of conductive materials effectively while creating very small droplets with conductivities in from about 7000 pico Siemens and greater. A compact system in which one, two or more parallel sprays can be obtained at close proximity in the order of 30 to 40 mm of each other in a compact package.
Abstract:
The invention comprises a method to increase the water absorption of tissue paper towel products by incorporating super-absorbent polymers (SAP) in between the laminated tissue plies. The SAP is dosed in selected places in the tissue towel manufacturing process without the need to substantially change the current converting or manufacturing process, or the major equipment that is used or the properties of the base sheet tissue paper.

Abstract:
An apparatus is provided for determining the location of a liquid-liquid or a liquid-gas interface in tanks or cavities and has particular use in determining the position of the explosive collar level in boreholes charged with water gel explosives. The apparatus consists of a sensing element which may be lowered into a cavity. Air is exhausted from the sensing element into the surrounding medium. Any restriction to air flow caused by the surrounding medium causes an increase in air pressure which increase signals the presence of an interface.
