Inventor: CONDOLIOS ELIE
IPC: B01D21/01
Filed: 1986-03-20
Abstract: A cloudy liquid to be clarified is inserted, after twice receiving flocculation additive, into the bottom of a belt of sludge (4a) in a clarification chamber (4) via a plurality of injectors (22) distributed over the area of said chamber. Uniform distribution of overall flow between these injectors is ensured by internal head loss. The clarified liquid is removed via an upper overflow (4b). Each injector is constituted by a flat cyclone and forms a jet which is highly diverting from its vertical axis in such a manner that the injected flowrate spreads out over an expansion zone belonging to said injector and meeting the expansion zones of adjacent injectors. Further, these jets set up swirling motion which prevents the formation of a layer of sludge having insufficient permeability. The sludge formed in the chamber (4) is directed via a central well (7) towards a secondary clarification sludge (3) situated beneath said chamber and supplying both clarified liquid and dense sludge.

Abstract: ATTACHMENT FOR AN OIL WELL SCREW PUMP SYSTEM          ABSTRACT OF THE DISCLOSURE         A pumping system for a heavy oil and sand slurry from a downhole location to the ground surface includes a conventional screw type pump having a rotor and stator.          At  the  bottom of  the  stator at the  inlet thereto  is mounted an attachment including a sleeve having a number of  slots  in the  side  surface  into which the material feeds.   Inside the sleeve is mounted a shaft having an auger flight along part of its length.  A coupling at the upper end of the shaft connects to the lower end of the rotor and can be engaged and released by rotation of the rotor. The auger flight assists in forming the materials including  any  excess  sand into  a  suitable  slurry  for feeding to the inlet of the pump.   The auger feeds the material more effectively to the inlet thus maximizing efficiency of  the pump.   The device  thus  avoids  sand blockages which are common problems in pumping systems of this type.

Title: Circuit breaker with low current magnetic trip
Inventor: MRENNA STEPHEN ALBERT
IPC: H01H71/40
Filed: 1990-08-22
Granted: 2000-05-02
Abstract: A circuit breaker having a trip mechanism comprising a primary armature which is attracted toward a bimetal by magnetic flux produced by a predetermined overcurrent flowing through the bimetal to unlatch an operating mechanism and open electrical contacts, includes a pivoted supplemental armature which is also attracted toward the bimetal by the overcurrent and which bears against and urges the primary armature toward the bimetal to thereby reduce the predetermined overcurrent at which the breaker opens the electrical contacts. The supplemental armature comprises a flat strip of magnetically permeable material which is bent at one end to form a hook which merely drops into a recess in the breaker housing. Integral flanges on the strip form a magnetic yoke which concentrates the magnetic flux to increase the sensitivity of the magnetic trip function.

Abstract: ABSTRACT OF THE DISCLOSURE    A serpentine tube inspection positioning spine formed from a plurality of identical links.  Each link has a convex first end and concave second end spaced along the longitudinal axis of the link whereby adjacent links may be mated together.  An axially extending bore  in  each  link  receives  a  continuous  cable maintained under tension by a spring attached to one end of the cable.  This places pressure on the links that serves to maintain the mated links in a rigid straight configuration while under compressive forces during insertion into a tube to be inspected.          The resilience of the spring also allows pivoting of adjacent links for travelling through a bend in the tube.
