Title: Stackable coreless roll carriage unit adapter for dispensers
Inventor: TAYLOR ANTWAIN DEMONE
IPC: B65H16/06
Filed: 2000-11-24
Abstract: A carriage unit adapter for solid or coreless rolls of paper material that are dispensed in a roll dispenser having slots defined on inner surfaces of side wall members thereof for receipt of said adapter and a back wall positioned a distance from the slots that is slightly greater than the radius of a solid or coreless roll. The carriage unit adapter includes: a pair of spaced apart arms joined by a connecting member having a front surface and a back surface, each arm having an outboard surface and an inboard surface including: (i) an outboard pin disposed on the outboard surface, the outboard pin configured to slidably engage a slot on an inner surface of a side wall member of the dispenser; and (ii) an inboard pin attached to the inboard surface, the inboard pin configured to engage a coreless roll of material. Each spaced apart arm has a length measured from the back surface of the connecting member to the center of the outboard pin that is greater than the distance between the slots and the back wall of the dispenser so that the back surface of the connecting member contacts the back wall of the dispenser to force the connecting member out of the same planar dimension as the outboard pins as they engage the slots. Each spaced apart arm further includes vertical separation elements.

Title: Improved method for forming conductive traces and printed circuits made thereby
Inventor: HERRICK WENDY A
IPC: H05K3/46
Filed: 1999-07-09
Abstract: A method of forming circuit lines on a substrate by applying a roughened conductive metal layer using a copper foil carrier. The copper foil is etched away, leaving the roughened conductive metal embedded in the surface of the substrate. The conductive metal may be treated to remove an oxide layer. A photoresist may also be applied over the treated conductive metal layer to define a fine line circuit pattern. The photoresist defining the fine line circuit pattern is then removed to expose trenches in accordance with the desired circuit pattern. Copper is applied into the trenches over the exposed conductive metal, and the remaining photoresist, and conductive metal underlying the remaining photoresist, is removed to finish the fine line circuit pattern.

Abstract: A dispenser heats and dispenses a melted material through an orifice. A push er (24) is slidably received within an interior of a cylindrical body (12) of t he dispenser and is movable relative to the forward end of the cylindrical body  (12). The pusher (24) is made up of an internally threaded cylinder that receives a driver screw and engages a stick of meltable material. The pusher  (24) is used to advance the meltable material toward the forward end of the body (12). The pusher (24) retracts when the meltable material is exhausted.  An induction heated system has a suspector plate with apertures that lead to  the nozzle. In use, the motor (42) automatically retracts the pusher (24) a slight increment when the motor (42) is turned off, which relieves static pressure on the elastic zone of the stick. A PC board (66) has a control circuit to control the advancing and retracting of the pusher (24) and for controlling the temperature of the inductor by regulating the flow of power to the inductor.

Filed: 2001-05-30
Abstract: Disclosed is a ratchet wrench having a drive head and a handle, the latter defining an elongate body. The body of the wrench is formed with a series of through cavities which are sized in steps for releasibly holding a series of correspondingly sized sockets. The sockets are retained in place frictionally by means of elastomeric inserts carried by and positioned to project inwardly of exposed annular side walls which define the cavities. Conveniently, the stored sockets may be forcibly expelled from the cavities in either of two opposed axial directions. For ready visual identification, markings are provided on the body of the wrench indicating the specific size of each socket-receiving cavity. The described features of the ratchet wrench also enable one quickly to verify the socket size, and allow socket placement over a fastener without requiring that the socket itself be first removed from the tool handle.

Title: Membrane-assisted fluid separation apparatus and method
Inventor: AL-HASSANI AISER
IPC: B01D63/02
Filed: 2001-06-22
Abstract: This present invention relates to a fluid separation module adapted to separate a given fluid mixture into permeate and retentate portions. The fluid separation module holds one or more bundles of hollow fiber membranes. The membranes may be composed of different kinds of membranes depending on the application being used to separate the fluid mixture. The fluid separation module may be used to separate fluid mixtures by a number of different processes, including but not limited to, pervaporation, vapour permeation, membrane distillation (both vacuum membrane distillation and direct contact membrane distillation), ultra filtration, microfiltration, nanofiltration, reverse osmosis, membrane stripping and gas separation. The present invention also provides an internal heat recovery process applied in association with those fluid separation applications where separation takes place by evaporation through the membrane of a large portion of the feed into permeate. Desalination and contaminated water purification by means of vacuum membrane distillation are just two examples where the internal heat recovery process may be applied. In these two examples, large portions of the feed are separated by membranes into a high purity water permeate stream by evaporation through the membranes and into a retentate stream containing a higher concentration of dissolved components than present in the feed. In this process the permeate vapour that is extracted from the fluid separation module is compressed by an external compressor to increase the temperature of the vapour higher than the temperature of the feed entering the separation module.  Heat from the permeate vapour at the elevated temperature is transferred back to the incoming feed fluid mixture entering the fluid separation module in a condenser/heat exchange.
