  • Patent number: 4229776
    Abstract: A capsule for use in aneroid pressure gauges comprising a pair of membranes sealed to each other along peripherally extending side edge regions to define a sealed, interior space therebetween. One of the membranes is formed having a centrally located charge retaining region. A capacitor plate is fixed to the other membrane and is disposed within the sealed interior space in opposed relationship to the charge retaining region. The means by which the capacitor plate is fastened to its respective membrane is electrically conductive and extends through the membrane while being electrically insulated therefrom. Changes in pressure are measured by measuring the changes in the capacitance between the capacitor plate and charge retaining region, the latter changes being effected by the changes in the distance between the membranes resulting from pressure fluctuations. The aneroid capsule is particularly suited for use in connection with an aneroid pressure gauge utilized in radiosondes.

  • Patent number: 4229250
    Abstract: Properties of mechanical paper pulp which is produced by grinding or otherwise frictionally acting on natural fibrous raw material containing plasticizable constituents which become heated to a temperature sufficiently high to soften the plasticizable constituents thereof are improved by the addition of paper filler material which is chemically inert to the pulp at a time which results in the filler being in contact therewith while the plasticizable constituents are plasticized and thus softened and sticky. This causes the filler, without chemical reaction, to adhere to the plasticized constituents and thus to the fibers of the pulp to result in improved properties of a totally mechanical pulp. The properties which are improved include the optical and printing properties of the paper made from the pulp.

  • Patent number: 4224104
    Abstract: A paper machine has a forming wire loop which transports a web to a detachment transfer roll situated inside said wire loop at a detaching location where the web is to be detached from the wire and transported to a press section. A relatively dry felt engages the web on a sector of the detachment transfer roll at the detaching location and receives the web from the wire and continues to transport the web, while it adheres to the felt, to the press section. The detachment of the web from the wire on the detachment transfer roll is facilitated by the centrifugal force acting on the web which results from the substantial change of direction undergone by the web on the detachment transfer roll. In one embodiment, the press felt is directed to cover the web on a sector of the detachment roll by a press suction roll located on substantially the same level as the detachment transfer roll, the press roll having a suction sector which facilitates transfer of the web from the wire to the felt.
