Granted: 2005-06-07
Abstract: A tank top pretreatment unit and assembly comprises a treatment unit installed inside a water treatment tank, such as a water softener tank, and in the top of the tank for treating the water either prior to its treatment with the primary treating medium in the tank or following such treatment. The treatment unit includes a plurality of chambers which are configured to contain a finely divided water treatment medium of a different kind than the primary treatment medium. Some of the elements may be arranged in series, but many or all are arranged in parallel flow which reduces the pressure drop of the water across the treatment unit, and the inlet openings to the chambers and outlet openings from the chambers are elevationally spaced from each other and the area of the outlet openings is less than the area of the inlet openings to maximize contact and dwell time in the chambers. A housing is also disclosed which surrounds and contains some or all of the chambers to permit positioning of the treatment unit beneath the level of the primary treating medium.

Patent CA-2259984-C (CA)
Inventor: KORNBLITH PAUL L
IPC: G01N1/30
Filed: 1997-07-10
Granted: 2008-10-07
Abstract: An improved system for screening a multiple of candidate therapeutic or chemotherapeutic agents for efficay as to a specific patient, in which a tissue sample from the patient is harvested, cultured and separately exposed to a plurality of treatments and/or therapeutic agents for the purpose of objectively identifying the best treatment or agent for the particular patient. Specific method innovations such as tissue sample preparation techniques render this method practically as well as theoretically useful. One particularly important tissue sample preparation technique is the initial preparation of cohesive multicellular particulates of the tissue sample, rather than enzymatically dissociated cell suspensions or preparations, for initial tissue culture monolayer preparation. By subjecting uniform samples of cells to a wide variety of active agents (and concentrations thereof), the most promising agent and concentration for treatment of a particular patient can be determined.

Title: Real time structured summary search engine
Inventor: REED JIM
IPC: G06F17/30
Filed: 1997-08-29
Granted: 2008-01-29
Abstract: A method of organizing electronic documents for storage and subsequent retrieval, involves storing a summary structure describing the structure of summary records associated with each document. Each structured summary record has at least one field representative of a characteristic of the document. A predetermined number of field values identify the value of the characteristic associated with the field. Predetermined keyword criteria associated with the field values are stored.  Each document is analyzed to build a text index listing the occurrence of unique significant words in the document. The text index is compared with the keyword criteria to determine the appropriate field value for the document. For example, one characteristic field might be related to topic, which could have the field values of "financial" or "sports". The preponderance of certain keyword criteria, such as "money" or "shares" would identify the document with the financial topic.

Title: Method and apparatus of converting heat to useful energy
Inventor: RHODES LAWRENCE B
IPC: F01K13/00
Filed: 1999-07-22
Granted: 2007-04-10
Abstract: A method and apparatus for implementing a thermodynamic cycle. A heated gaseous working stream including a low boiling point component and a higher boiling point component is separated, and the low boiling point component is expanded to transform the energy of the stream into useable form and to provide an expanded relatively rich stream. This expanded rich stream is then split into two streams, one of which is expanded further to obtain further energy, resulting in a spent stream, the other of which is extracted. The lean unexpanded stream and the spent rich stream are then combined in a regenerating subsystem with the extracted stream to reproduce the working stream, which is then efficiently heated in a heater to provide the heated gaseous working stream that is separated.

Granted: 2002-12-10
Abstract: A refrigerator temperature control system includes a passageway for delivering a supply of cooling air from a freezer compartment to a fresh food compartment.      A diverter member is positioned about the passageway in the freezer compartment for channeling the air through the passageway. A freezer compartment temperature sensor is routed from a temperature control unit in the fresh food compartment, through a bore formed in an insert which defines the air passageway, into a specialized chamber formed as part of the diverter member. The chamber is in fluid communication with the flow of air to the fresh food compartment through a bleed hole. To increase its surface area, the sensor is preferably coiled within the chamber and an insulation jacket extends about the sensor from within the fresh food compartment, with the insulation jacket creating a seal within the bore. In addition, a supporting sleeve extends about the sensor between the temperature control unit and the coiled portion of the sensor.

Abstract: The invention provides a device and a method of metering and displaying immediate and/or accumulated energy consumption at a place of consumption, such as electricity, water or heating consumption in a household, said device comprising a recording unit which records and sums an immediate energy consumption on the basis of regular measurements and stores these measurements for the calculation of an average consumption, a display comprising at least one display unit capable of displaying the relationship between an accumulated energy consumption and the calculated average consumption for a selected period of time on a percentage scale. The display preferably exhibits a first display unit which displays the accumulated energy consumption on an energy scale preferably from 0-200 %, where 100 % corresponds to the calculated average consumption, and a second display unit which may show the immediate power consumption relative to a selected reference consumption, preferably on a percentage power scale from 0-100%, where the selected reference consumption, which corresponds to the maximally recorded power, corresponds to 80 % on the power scale. A consumption meter according to the invention hereby ensures that the user is more easily motivated to cut down on the energy, as he immediately gets a quickvisual indication in his energy consumption because of e.g. an energy saving measure, such as the use of low-energy bulbs in one or more lamps or the like.
