Title: Method and device for keeping a coating rod and a rod cradle in a bar coater clean and for preventing leakage of lubrication and/or cooling water
Inventor: RANTANEN RAUNO
IPC: D21H25/12

Granted: 2005-06-28
Abstract: A method and device for keeping a coat ing rod and a rod cradle in a bar coater clean and for preventing leakage of the lubrication and/or cooling water used in the bar coater is disclosed. The invention is intended for a bar coater in which the coating rod (41) is, supported revolvingly in a rod cradle substantially over its entire length (42). The rod cradle (42) is attached to the frame constructions (50) of the coater. The rod cradle is also provided with at least one groove (43, 44) substantially parallel to the coating rod (41) and open towards said coating rod, in which grooves(s) water is circulated to lubricate, cleanse and/or cool the coating rod (41) and the rod cradle (42). The coating rod (41) is loaded towards the base (B) to be coated by loading the rod cradle (42). The rod cradle (42) and the sealing lips (45, 47) of the rod cradle are loaded so that the loading seals the glide faces (46, 48) between the coating rod (41) and the rod cradle (42) substantially over the entire length of the rod cradle and prevents leakage, or at least substantially reduces leakage, from the water grooves (43, 44).

Title: Improved water treatment system
Inventor: HONCHAR DENNIS R
IPC: C02F1/68
Filed: 1992-12-14
Granted: 1998-12-29
Abstract: The present invention comprises an improved method and apparatus for treating water in heat exchange systems.  The present invention automatically and inexpensively provides an effective chemical to process water systems at times and in proportion to the need for water treatment in such systems.          When used in evaporative cooling systems, the present invention adds the treatment chemical to the system via the make-up water.  The make-up water acquires a substantially constant concentration of treatment chemical as it is passed through a device containing a treatment chemical.  The constant concentration of chemical is achieved by dividing the make-up flow into two streams within the device, saturating the smaller of the two streams with chemical, and re-mixing the two streams.  The biocide agent used in the preferred embodiment of the invention is prilled elemental iodine.

Title: Process to separate a mixture of water, solids or sludges, non-volatile hydrocarbons and other accompanying substances
Inventor: GOSSEL CHRISTIAN
IPC: C10G1/04
Filed: 1993-03-11
Granted: 1999-05-04
Abstract: A process separates a mixture of water, solids or sludges, non-volatile hydrocarbons, and other accompanying substances by means of solvent extraction.  Mixtures that consist primarily of solids or sludge with non-volatile hydrocarbons are especially suited for application of this process, if they occur as a concentrated sludge from a settling pond of bitumen production from tar sands. However, it is also possible to use the process to decontaminate soil contaminated by crude oil spillage.  The process makes it possible to process, and to break down to its primary constituents, the oil-bearing sludge that has accumulated during the production of bitumen from tar sands using the hot water method, and which is stored in settling ponds and constitutes a permanent danger to the environment.  The recycled water is then free of hydrocarbons.  This environmentally compatible process can be carried out with low energy and operation costs.

Title: Instrument switch having integrated overcurrent protection
Inventor: KRASSER FRITZ
IPC: H01H1/58
Filed: 1994-03-16
Granted: 1997-08-19
Abstract: An electrical instrument switch includes a rocker switch for manual on-and-off switching and that is seated in an insulation housing.  Depending on the pivot position, the rocker switch moves, with a working end that dips into the housing interior, a contact bridge between the closed position of its contact and the closed position of its contact.  The contact bridge is electrically connected in series with a contact spring that can be triggered thermally and hence acts as an overcurrent protection.  The contact spring can move between its contact position and its open position.  The contact spring is mechanically prestressed in the direction of its open position.  When overcurrent occurs, it is transferred out of its contact position into its open position by means of a thermal triggering element.          A pivot of the rocker switch counter to the mechanical prestress, in the tipping direction of the contact spring, guides the contact spring from its open position back into its contact position.

Abstract: An automatic rotary sorter system for sorting objects from a source stream into a plurality of destination streams which are spaced apart both horizontally and vertically. The automatic rotary sorter system of the present invention includes an object source conveyor, a rotating distribution assembly, and an object receiving assembly. The rotating distribution assembly of the automatic rotary sorter system is provided with an upright drive shaft and several receiving and discharging wings.

Title: Method of curing dual-coated optical fiber
Inventor: BARON WILLIAM JAMES
IPC: C03C25/1065
Filed: 1994-08-29
Granted: 2002-04-16
Abstract: A method of curing a dual-coated optical fiber is disclosed in which primary and secondary coating materials are simultaneously applied to a glass fiber and then simultaneously cured. The primary coating material encloses and engages the glass fiber, while the secondary coating material encloses and engages the primary coating material. A photoinitiator is added to the primary and secondary coating materials. The photoinitiators respond to electromagnetic energy radiated from a source of electromagnetic radiation comprising one or more curing lamps having identical emission spectra; however, the photoinitiator added to the primary coating material is selected to be substantially more responsive to the radiation source than the photoinitiator added to the secondary coating material. The photoinitiator associated with the primary coating has a photoactive region in the vicinity of a peak of the emission spectrum, whereas the photoinitiator associated with the secondary coating has a photoactive region where the emission spectrum of the curing lamps has a substantially lower intensity.

Granted: 1997-09-23
Abstract: A system for detecting an overflow from a storage tank holding a liquid and/or slurry.  An inlet to an overflow box communicates with the tank at an overflow point and receives any overflow from the tank.  A main drain pipe communicates with the overflow box and leads to a drain.  An overflow  discharge pipe having a smaller internal diameter than that of the main drain pipe also communicates with the overflow box, but is located closer to the inlet that the main drain pipe.   The overflow discharge pipe provides a first drainage of any overflow from the tank to the main drain pipe, and is provided with sensor means for detecting and/or measuring a flow rate of any overflow through the overflow discharge pipe.  A controller provides a signal to activate an alarm in order to alert an operator that an overflow condition exists.  Alternatively, the signal could be used to control a flow rate of liquid or slurry into the tank by providing a signal to flow rate controller means to reduce the flow rate of liquid or semi-liquid into the tank whenever any overflow is detected within the overflow discharge pipe by the sensor means.

Title: Object-oriented cursor tool
Inventor: WISHNIE JEFFREY
IPC: G06F17/21
Filed: 1994-01-03
Granted: 2001-03-13
Abstract: An innovative system and method provide a cursor tool framework and tool server with support for multiple cursors on any given system, and supports the selection of a cursor tool utilizing a cursor. The framework and server facilitate the association of cursor tools to a cursor in a process independent space such that tools can be used cross-process and cross-document. The framework also provides default functionality for communication and negotiation among cursor tools and the canvas on which they are used. This negotiation allows any cursor tool and any document to function together such that the cursor tool can be written without the knowledge of the document developer. The framework provides implementation for the distribution of cursor tools across processes and documents in an efficient manner such that documents need not be aware of tools until such time as the tool has successfully negotiated with the document for the right to alter the documents data.
