IPC: D21F5/04

Granted: 1978-12-19
Abstract: ABSTRACT OF THE DISCLOSURE     The described apparatus has utility as a doctor on a paper machine, as a drying element in an aircap dryer and as a sealing element in such a dryer.  It involves a foot portion having an outer surface generally conform-ing to the curvature of the cylinder surface on which it is used.  It is resiliently supported in close juxtaposition to the cylinder surface so that a gap diminishing in thickness towards one longitudinal edge of the foot por-tion is provided. At least two rows of nozzles communicate through the foot portion in order to project pressurized air into the gap.  Each nozzle is angled relative to three orthogonal planes, one of which is tangent to the cylinder surface at the point where the nozzle axis meets the sur-face, another of which is parallel to the longitudinal edge of the foot portion.  The flow from the nozzles is such as to support the foot portion and to seal the support flow from any disorganized flows.  The jetting air will tend to aid in doctoring a paper sheet from the cylinder surface or to dry a paper sheet passing thereunder or to seal an opening from the passage of air therethrough if the opening is defined by a cylindrical surface.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of and system for locating a position in which a plurality of frequency standard devices (atomic clocks) based on the action of the natural frequencies associated with transitions between energy states in atoms and/or molecules are synchronized or phase compared at the same initial location.          Two of three frequency standard devices, in a two-dimensional embodiment, are placed at transmitting stations on a known baseline.  The third device is at a third station, a receiving station, which receives signals from the two transmitting sta-tions.  At each transmitting station, means are provided for producing and transmitting a radio frequency carrier signal of fixed frequency and of fixed phase under the control of the frequency standard device associated with the respective station.          The radio frequency carrier signals produced at the different transmitting stations differ in frequency.  The radio frequency carrier signal produced at each transmitting station is modulated with a single, low frequency signal produced under the control of the same frequency standard device which controls the means which produce the radio frequency carrier.  At the receiving station, means are provided for producing a reference signal, corresponding, in frequency, to the low frequency modulating signal and two local radio frequency signals corresponding, in frequency, to the radio frequency carrier signals transmitted.          These signal producing means at the receiving station are con-trolled by a frequency standard device (atomic clock) associated with the receiving station.  The phase of the reference signal is compared, at the receiving station, with the phase of the modulating signals recovered from the radio frequency carriers to determine respective phase differences, the differences rep-resenting coarse position data from which the total number of phase rotations (full lanes) the receiving station is from each of the transmitting stations are determined.  The phase relation-ships between each of the received radio frequency carrier signals and the respective one of the two radio frequency signals produced at the receiving station are determined, the relation-ships representing fine position data which are measurements of the receiving station position within a given phase rotation (lane).

Abstract: ABSTRACT OF THE DISCLOSURE         A workpiece is passed through an etching tank, and then through at least an upstream rinsing tank and a downstream rinsi rinsing tank.  In each of the tanks a respective liquid is pumped up from a sump at the bottom and sprayed over the workpiece as it passes through.  Liquid is drawn out of the upstream rinse tank and mixed with regenerator chemicals to replenish liquid lost by the etcher and maintain the liquid in the etcher at full strength.  Liquid lost from the upstream rinser in this manner is replenished by introduction into the downstream rinser of fresh water and passage of liquid from the downstream rinser to the upstream rinser through an overflow that maintains a higher liquid level in the downstream rinser than in the upstream rinser.

Abstract: ABSTRACT           Preparation of compositions of silver and CeO2  by powder metallurgy techniques overcomes problems inherent in melting silver and pure cerium and subsequently internally oxi-dizing the cerium in the mixture.  Small concentrations of CeO2 substantially improve the electrical contact properties of silver.  Silver with dispersed CeO2  is superior to silver alone for use as an electrical contact because of much greater resis-tance to arc erosion and welding and only slightly higher contact resistance.
