Abstract: A method and system for determining the mineral content of a sample using an electron microscope. The method includes directing an electron beam toward an area of interest of a sample, the area of interest comprising an unknown composition of minerals. The working distance between the backscattered electron detector of the microscope and the area of interest of the sample is determined. Compensation is made for the difference between the working distance and a predetermined working distance in which the predetermined working distance being the working distance that provides desired grayscale values for detected backscattered electrons. One way of compensating for working distance variation is to used an autofocus feature of the microscope to adjust the working distance. Backscattered electrons from the area of interest of the sample are then detected.

Abstract: A multi-part kit for administering at least one active pharmaceutical ingredient including at least one piece of chewing gum including the active pharmaceutical ingredient, the piece of chewing gum comprising gum base; and at least one further flavor-containing formulation; wherein the gum base content of the at least one further flavor-containing formulation is less than 70% by weight of the gum base content of said piece of chewing gum.

Abstract: The invention relates to a particulate material for controlled release of active ingredients, the particulate material comprising a combination of one or more active ingredients, excluding nicotine, and an inorganic mineral filler, wherein the active ingredient is reversibly absorbed into and/or adsorbed onto the inorganic mineral filler, and wherein the BET specific surface area of the inorganic mineral filler is above 15 m2/g, the BET specific surface area measured in accordance with ISO 9277. The invention is particularly advantageous for controlled release of active ingredients.

Abstract: A station for distributing products to a line for supplying packaging machines or for storage, if necessary, comprises a first conveyor having an end which is driven so as to oscillate between a raised configuration and a lowered, receiving configuration in which it is aligned with the output of a product-conveyor line and is disposed above the center-line of a line perpendicular thereto for supplying a packaging machine, and a first product-transfer unit which is aligned with and below the first conveyor and is driven in an oscillatory manner in order to move its input from a collecting position in which it is aligned with the product-conveyor line while the first conveyor is in the raised configuration, to a discharge position in which it is coplanar with the supply line.

Abstract: A centrifugal pump has a rising characteristic at low flows, leading to pressure pulsations in the fuel system at low flow. A pressure difference regulating valve at the pump discharge has a frequency response such that the valve does not significantly move in response to the pulsations. The valve responds to less rapid changes, thereby avoiding high pressure loss at high flows.
