Title: Foam removal from receiving tanks of gas sparged hydrocyclones
Inventor: CHAMBLEE WAYNE J
IPC: B01D19/02
Filed: 1991-07-04
Abstract: ABSTRACT      Foam typically forms in a receiving tank from either the underflow or overflow from a gas sparged hydrocyclone.  Particularly in processing of paper pulp to deink the pulp or to remove sticky contaminants from it, the foam in the receiving tank has many undesirable materials which are preferably removed.  Foam from the receiving tank is removed with a vacuum box or an overflow weir.  To facilitate concentration of the foam, the discharge of fluent material from the bottom of the receiving tank is preferably via a tangential discharge line so that a swirling action takes place in the tank and the foam collects near the cylindrical side wall of the tank. The foam may be removed by vacuum caused by a blower, and the foam and entrained liquid is separated from the air before the air reaches the blower.  The foam and entrained liquid may be dewatered, or compounds therein having a high BOD and COD load are separated.  An alternative construction of receiving tank includes a gas introduction device at one side portion causing gas to blow foam toward an opposite side portion to a foam outlet, with a liquid spray for breaking foam bubbles at the outlet.  A generally horizontal baffle, and optional vertical baffles, prevent short circuiting of fluent material from an inlet to the fluent material outlet of the tank.

Abstract: INVENTOR:   JACQUES MEIER INVENTION:  APPARATUS FOR STAPLING MULTIPART PRINTED PRODUCTS                       ABSTRACT OF THE DISCLOSURE          Printed products are stapled in that they are guided between a stapling-head arrangement and a staple-closing arrangement. The stapling-head arrangement consists of a number of stapling heads revolvingly moved along a closed revolving path. A section of this closed revolving path thereby extends substantially parallel to the travel path of the printed products. The staple-closing arrangement comprises a number of countersupports likewise moved along a closed revolving path also having a section extending substantially parallel to the travel path of the printed products. A countersupport co-acts in each case with a stapling head to close the respective inserted staple. Consequently, during the stapling operation, the stapling heads and the countersupports run along and cover a certain distance together with the respective printed products to be stapled.     -- 1    .

IPC: G01F23/284
Filed: 1992-09-17
Abstract: ABSTRACT        A water level measurement system for use with a pressurised power plant boiler comprises a tubular pressure vessel for attachment to one end of the boiler such that the water level in the pressure vessel is the same as in the boiler.   The pressure vessel has a central rod-like conductor which together with the vessel forms a coaxial RF waveguide.  A pair of spaced reference discontinuities are provided in the conductor above the maximum level of the water,  so that an RF pulse injected into the waveguide is reflected successively by both discontinuities and the surface of the water. The level of the water can then be determined independently of changes in the dielectric constant of the vapour above it, from the ratio between the time intervals between the first and second reflected pulses and between the first and third reflected pulses.  The conductor is mounted at the top of the pressure vessel by way of a pressure seal and a ceramic insulator.

Title: Call routing in mobile telephone systems
Inventor: SAWYER FRANCOIS
IPC: H04W8/06
Filed: 1992-10-22
Abstract: A method and apparatus for providing continuous and accurate location information pertaining to a mobile telephone subscriber wherein a temporary location is utilized. Upon entry to a visited system the mobile subscriber either transmits a registration access or a call access. If the mobile subscriber sends a registration access, the visited system acknowledges the registration, records the mobile subscriber's presence and signals the mobile subscriber's home system of the mobile' s presence. Receipt of the mobile's location from the visited system causes the mobile subscriber's home system to update its location data for that particular mobile. If the mobile subscriber initiates a call access from within the visited system without registering within the visited system, the visited system allocates a record for the mobile indicating within the record that it has not received a registration from the mobile and transmits to the home system a temporary location signal. The home system, upon receipt of the temporary location stores the location without deleting the existing location data for the mobile subscriber. The temporary location data is deleted upon the conclusion of the mobile subscriber's call from within the visited system. The temporary location data is used by the mobile subscriber' s home system to effectuate the routing of calls for the mobile subscriber.
