  • Patent number: 5273036
    Abstract: The apparatus for monitoring respiration comprises a photoplethysmographic sensor whose LED transmitter element(s) is/(are) excited by a monitoring unit with a specified control power and/or control signal sequence or frequency. By means of a signal processing unit, both the frequency and depth of respiration can be measured, as can the pulse frequency or oxygen saturation of the peripheral blood. The use of such an apparatus guarantees significantly more reliable monitoring of respiration than the impedance pneumographic methods of the prior art.

  • Patent number: 5259859
    Abstract: A lightweight vacuum pickup is constructed using a honeycomb platen as the sheet engaging member of the pickup. The cells of the honeycomb platen are selectively sealed to control the amount of vacuum drawn through the platen. When used to transfer heat softened glass sheets, the lower sheet engaging surface of the platen is sealed with a dense material cloth which restricts airflow therethrough. The cloth includes holes positioned within the periphery of the glass sheet to be engaged by the pickup.

  • Patent number: 5110336
    Abstract: The number of bent laminated glass windshields having bull's-eyes that adversely affect its optical properties is reduced by using amorphous precipitated silica particles such as is used as flatting agents for paints, as a parting material between a pair of glass sheets during bending. The particles form relatively soft agglomerates that are milled and classified to produce a narrow distribution of particle sizes as compared to the distribution found in untreated silica, such as diatomaceous earths previously used as a parting material.

  • Patent number: 5085680
    Abstract: A longitudinally extending row of closely spaced elongated flexible springs extend over an elongated slot of a furnace to prevent heat loss. The springs are deflected in turn as an arm moves along the length of the slot and the springs return to their original state after the arm passes by. The arm holds a glass handling device which holds a glass sheet within the furnace. The arm moves along the length of the slot so as to transport the glass sheet through the sections of the heat treating furnace.

  • Patent number: 5062876
    Abstract: This invention relates to a novel bushing apparatus having unique nozzles or projecting orifices for the production of round glass fibers. Particularly, it relates to a bushing having tips with cross-sections in the form of finite-sided polygons. It is shown that the use of noncircular tips to produce round fibers can result in higher tip packing densities, higher throughputs, and increased forming process stability than are now possible using the present state of the art. Tips with square cross-sections are shown to be the most preferred embodiment.
