Abstract: A greywater treatment and reuse system includes a collector for collecting greywater, a distributor for distributing treated greywater for reuse, and a treatment and storage device for treating collected greywater and for storing treated greywater before the greywater is sent to the distributor for reuse. The treatment and storage device is fluidly connected to the collector by a delivery line and is fluidly connected to the distributor by a distribution line. The treatment and storage device includes a first filter that is fluidly connected to a second filter by a connection line and a chlorinator fluidly connected to the delivery line, the chlorinator injecting a first dose of chlorine into the delivery line.

Abstract: Polymer films having a number of wells can be prepared by contacting the polymer with a solvent which causes the polymer film to swell and produce blisters. When the film is dried the blisters collapse to form wells. The polymer film is supported on a substrate such as silica or glass and the wells are often arranged in an array. An example of a polymer which can be used is poly(d,l-lactide).

Abstract: The present invention comprises an electromagnetophoretic ink material for use as electronic and magnetic display elements. In particular, the present invention relates to the preparation and use of microencapsulated aspect elements having both an electrostatic layer and a magnetic layer, and that can be addressed to produce a display aspect by the application of external electric fields and external magnetic fields.

Abstract: An automated system for dip coating a superconducting material on a substrate is disclosed. The system includes an actuator, a pick up station, a dip coating station that comprises a reservoir of a dip coating formulation, a drying station that includes a source of heated air and a conveyor for moving the actuator from the pick up station to the dip coating station and from the dip coating station to the drying station. The actuator includes an arm for carrying a substrate. The arm is capable of being moved vertically downward to submerse the substrate in the dip coating reservoir and the arm is also capable of being moved vertically upward to lift the substrate out of the dip coating reservoir. A method for automatically dip coating a substrate with a superconducting material is also disclosed.

Abstract: A tilt latch (10) for a sash window (12) has a bolt stop. The sash window (12) is disposed within opposed guide rails (16) on a master frame (14). The sash window (12) is comprised of a top sash rail (20), a base (22) and two stiles (24,26) connected together at their extremities. The tilt-latch (10) is adapted for releasably securing the sash window (12) to the master frame (14). The tilt-latch (10) is comprised of a housing (42) adapted to be supported by the top rail (20). The housing (42) has an outward end opening (44). A latch bolt (46) is disposed within the housing (42) and has a nose adapted for engaging a respective one of the guide rails (16). A protrusion (80) is located either on the latch bolt (46) or the housing (42) and a lock wall (86) is located either on the housing (42) or the latch bolt (46).

Abstract: A pivot corner adapted for operative engagement with a sash balance brake assembly of a pivotable sash window is disclosed. The pivot corner comprises a housing having an axial bore and a pivot pin. The pivot pin has a first portion disposed within the bore and a second portion extending outwardly therefrom and adapted for operative engagement with the brake assembly. The axial bore and the first pin portion are complementarily octagonal in cross-section. The first pin portion has a cross-section sufficiently smaller than the cross-section of the axial bore to permit non-destructive rotation of the pin relative to the housing upon application of a predetermined torque.

Abstract: A process for preparing a proppant charge comprising individual sand particles coated with a pre-cured thermosettable resin. Sand is mixed with melted resin, and the resin-coated sand is heated under conditions which cure the resin. Mixing is carried out with sufficient mechanical shearing action to limit agglomeration of the resin-coated sand particles.
