Abstract: A connector 10 is disclosed of the type that interconnects and mechanically secures two electrical conductors together, particularly non-insulated, flat ribbon conductors 46. The connector includes a C-shaped clamping member 42 and a wedge 44 that is conformably received therewithin thereby forming a conductor receiving channel on each side of the wedge 44, between the wedge 44 and the walls of the clamping member 42.      As the wedge 44 is forced into the clamping member 42 the walls are elastically deflect outwardly, applying substantial force against the conductors, thereby establishing good electrical contact and a strong mechanical interconnection of the two conductors. The connector 10 is self aligning for a variety of conductor sizes where at least one is a flat conductor. This is achieved by means of a novel combination of concave and convex surfaces on the clamping member and a pair of flat converging surfaces on the wedge, one of which includes a concave portion.

Abstract: A puzzle comprises a box formed by a sleeve and a drawer, similar to a matchbox, but with the sleeve closed at one end and open at the other end. The length of the drawer is equal to the interior length of the sleeve so that, when the drawer is inserted fully into the sleeve until its interior end abuts the closed end of the sleeve, the open end of the sleeve is closed by the outer end of the drawer, giving the appearance of a box with similar end panels. The edge of the sleeve at the open end has indents in at least two of its opposite faces. The drawer has corresponding protrusions which correspond exactly to the indents. When the drawer is fully inserted, the protrusions fill the indents and complete the respective surfaces. To open the box, the protrusions are grasped between finger and thumb and pulled outwards. Preferably, the box is shaped like a crate with longitudinal parallel slats simulating plank pieces and transverse slats simulating strapping. Each indent is formed by terminating one of the slats beneath the transverse slat. The corresponding protrusion is a slat portion equal to the missing section of the terminated slat. When the box is closed, the joint between the terminated slat and the slat portions is beneath the transverse slat, giving the impression that the slat portion is a continuation of the terminated slat.

Title: High water recovery membrane purification process
Inventor: AL-SAMADI RIAD A
IPC: C02F9/02
Filed: 1996-10-01
Granted: 1999-03-30
Abstract: Disclosed is a two-stage high pressure high recovery process utilizing two reverse osmosis membrane systems intended to provide very high overall water recoveries from contaminated inorganic scale-containing water in an economical manner while preventing scale formation on the membrane and prolonging the useful life of themembrane. The first stage of the process involves using a low pressure membrane system to preconcentrate scale compounds while purifying the bulk volume of the scale-containing water (using antiscalants with pH control) and combining the influent water with a recycle stream of concentrate from the second stage membrane process in order to prevent scale formation. This first stage membrane system is followed by a second stage membrane system wherein the concentrate from the first stage membrane system is treated further at higher pressure in order to provide purification of the remaining preconcentrated stream and achieve very high overall water recoveries. Scale formation in the first stage and second stage membrane systems is prevented by the recycle of "softened" water containing a very low concentration of scale-forming compounds and containing a high concentration of soluble salts to both stages in a specific proportion that represents an economically viable process, while ensuring adequate permeatequality. The second stage membrane concentrate stream is "softened" whereby hardness compounds such as calcium, magnesium, carbonate, sulphate, silica and other sparingly soluble compounds are removed by suitable means before it is recycled to the twomembrane purifying stages.
