  • Patent number: 5762711
    Abstract: Protective and security coatings are applied to an integrated circuit by periodically passing the integrated circuit through a flame spray containing molten particles of the coating composition. The integrated circuit is attached to a fixture that is cooled with a coolant that is applied to the integrated circuit. The distance between the flame spray gun and the integrated circuit is controlled so that the particles are molten when they strike the circuit but the circuit heating is minimized. A flame resistant mask retains the integrated circuit on the fixture. The mask is constructed of a low thermally conductive material and the fixture is constructed of a high thermally conducive material.

  • Patent number: 5762759
    Abstract: A papermaking machine uses a low pressure water jet mounted on a pneumatic actuator for movement at least as fast in the cross machine direction as the paper web moves in the machine direction for a distance of 2 to 12 inches. The jet rapidly cuts a tail with a blunt edge of 2 to 12 inches wide from the web. The actuator is mounted on a screw or belt driven carriage to traverse the web and expand the tail after it has been threaded through the dryer section until the tail encompass the entire web and thus completes the threading process. A controller coordinates an air jet positioned beneath a doctor blade and a vacuum suction roll which engages the last press roll. The air jet and vacuum suction roll are actuated when the blunt end of the tail engages the doctor blade. In this way a tail with little or no streamer is formed and blown onto a dryer fabric supported on a vacuum suction roll which leads the tail into a single tier dryer section.

  • Patent number: 5762675
    Abstract: A method of producing amorphous sample bodies that can be used for optical spectral analysis and X-ray spectral analysis, by batch-wise smelting in a crucible a mixture of analysis sample and a flux. The method is characterized by allowing a controlled flow of molten material to run out of the crucible and successively down onto a horizontal receiving surface and there form the sample bodies. The mixture is smelted suitably at a temperature of between 800.degree. and 1300.degree. C., preferably at about 1000.degree. C., and is carried out in a crucible having a hole in the bottom thereof. A apparatus for producing such amorphous sample bodies is also disclosed. The apparatus includes a smelt crucible provided with an opening in its lower part and which is designed to be downwardly tapered at least inside in order to prevent the mixture from coming out, but to facilitate running of molten material through the opening.

  • Patent number: 5759272
    Abstract: A manual sealing unit consists of a crane-like bracket (1), which is mounted to rotate around a vertical axis (9). A boom (2) is connected to pivot around a vertical axis (12) and around a horizontal axis (15) at the free end (10) of a horizontal segment (11) of the bracket (1). Supply conduits (6, 7), by which the components of the sealing compound are conveyed to a mixing device (4) and a manual sealing nozzle (3) that is connected to the latter, are fastened to the bracket (1) and the boom (2). In the area of the joint between the bracket (1) and the boom (2), the conduits (6 and 7) are arranged in bends (21) and have a rotating joint (22) there, so that the movability of the boom (2) is not hampered. The boom (2) is loaded upward by a pneumatic cylinder (19), so that the combination of the mixing device (4) and the sealing nozzle (3) for an operator executing the manual sealing is virtually weightless.

  • Patent number: 5759345
    Abstract: To recover the sodium-sulphur compounds following sodium-based pulp processing, e.g. the ASAM process or basic or acidic sodium sulphite processes, the waste liquor is burnt in a lye burning vat (1) with liquid slag extraction and the exhaust gases are subjected to multi-stage purification with dry fly-ash recovery and the gaseous sulphur compounds are also separated in a multi-stage washing process. The water-soluble components of the fly-ash are taken to the waste liquor to be burnt and thus the sulphur to be recovered in the slag is increased. The slag is dissolved in water and the dissolved sodium compounds are converted by multi-stage carbonisation with a part of the purified flue gas into sodium bicarbonate and H.sub.2 S. The H.sub.2 S is burnt and finally converted into sodium sulphite so that the desired lye for pulping cellulose can be made up from sodium sulphite and carbonate.

  • Patent number: 5759596
    Abstract: The present invention provides refrigeratable yeast-leavened dough compositions and methods of making such doughs. In a first embodiment, a dough composition of the invention is made by rehydrating dried yeast at chilled temperatures, which causes selective lysing (a loss in the selectivity of the yeast plasma membrane). Such a dough composition exhibits a cold sensitivity in that the yeast is capable of leavening the dough at elevated temperatures, but becomes inactive at refrigeration temperatures. In another embodiment, the dough composition and the strain of yeast used therein are chosen to limit the total leavening action of the yeast by controlling the amount of substrate in the dough fermentable by the yeast. In a third embodiment, a dough comprises a mixture of flour, water and a mutant yeast which is low temperature sensitive. Such an "lts" yeast is active at elevated temperatures, but becomes substantially inactive at refrigeration temperatures.

  • Patent number: 5755880
    Abstract: A double walled drum of concentric cylinders having end seals and insulation between the cylinders. The drum is open at both ends and rotates on its center longitudinal axis which is pitched from the horizontal with the entrance on the high side. Diameter restrictions at the entrance and discharge ends of the drum increase product residence time. Lifters at the entrance end discharge end push flexible strandular food subject to microbial spoilage such as strands of cooked pasta away from the entrance and out the discharge. Pins are mounted perpendicular to the inner cylinder wall and point to the central axis of the drum. Liquids such as acid and oil are sprayed onto the food in the drum from a spray bar or spray manifold. The pins continuously lift and separate the strands of food while it moves through the drum, and mix the liquid and product, resulting in a uniform coating. This process and apparatus produce a uniformly coated flexible strandular food such as spaghetti with minimal temperature loss.

  • Patent number: 5756141
    Abstract: A method for processing pulpy fruit puree or pulpy juice or reprocessing traditional evaporative pulpy citrus concentrate into products which do not resemble conventional juices or conventional concentrated juices, and more particularly, a packaged high Brix clarified juice concentrate which is ready to pour at freezer temperatures, to a 100% natural fruit juice produced from the clarified juice concentrate, to a blended reduced bitterness fruit juice product, and to a 100% juice-blend pulpy fruit product. The invention provides novel all-natural juice blends, including a 100% natural fruit juice containing aloe vera. The clarified juice concentrate as ready-to-pour 6+1 concentrates at freezer temperatures above -15.degree. C. In contrast, the traditional 3+1 frozen juice concentrate becomes frozen at common domestic freezer temperatures of -5.degree. to -15.degree. C. and it is inconvenient to pour and to mix with water.

  • Patent number: 5753080
    Abstract: In a method of recovering fibers from white water using a filter including a vat and a rotating filter surface (such as a disc filter), auxiliary pulp is supplied to the area of the vat where the cleaned and rotating filter surface meets the pulp surface in the vat. The consistency difference in the filter vat is adjusted by controlling the auxiliary pulp flow, or by adding cloudy filtrate to the auxiliary pulp prior to the filter vat. The auxiliary pulp is preferably supplied to the filter by using directing nozzles or other supply structures, and essentially evenly over the entire radial width of the filter surface.
