Title: High rate filtration system
Inventor: DEW WILLIAM FREDERICK JR
IPC: B01D24/26
Filed: 1997-12-09
Granted: 2001-08-23
Abstract: A high rate, upflow filtration system is described in which a compressible, fibrous lump filtration media is compressed to adjust the porosity and collector size of the media in the bed and to provide a porosity gradient within the bed proceeding from more porous to less porous in a direction opposite to the flow of fluid so that filtration proceeds in a direction from a more porous to a less porous filter bed. Larger particles are removed by the more porous media and successively smaller particles are removed as the filter bed becomes less porous. The system is capable of reducing the turbidity of influent municipal wastewater from about 8 NTU to about 2 NTU at a wastewater flow rate of from about 820 to 1230 L/m<2>.min (20 to 30 gal/ft<2>.min), at a bed compression ratio of from about 15 to 40 percent, and at a backwash rate of from about 1 to 6 percent based on the total wastewater passing through the filter.

Inventor: HAUSE SANDRA LYNN
IPC: G06F3/048
Filed: 1990-07-16
Granted: 1999-04-13
Abstract: In display screen or system technology, a window is a viewing area on the video display.  It may be the full screen region or a smaller region represented within a border of typically rectangular shape into which data from application programs and the like may be written for display.  One or more windows may appear on the face of a video display  screen.   In  the context of the present invention, the window areas are of variable size selected by the operator and resizing of the regions or areas within each variable window must be modified to suit the newly selected window size.  Attributes associated with the regions to be placed within a given window include those for relative priority of display within the window, location within the window and the minimum dimensions of each region to be included within the window.  Program controlled operations examine the minimum specifications for  the  regions  to be  displayed within  a window  in comparison  with  the  operator-selected  window  size  in which the regions are to be displayed, and aportion the available window space among the regions to be displayed in accordance with their relative priority and location in the window and their  specified minimum sizes,  and generate the control parameters necessary for recreating the window display with the appropriate regional spaces allocated and located within the window.

Granted: 1999-12-28
Abstract: A single-use, throw-away brushing device, in particular for teeth. The single-use, throw-away brush comprises a flexible holder for toothpaste or other treating product (1) constituted by a gripping handle having a non-flexible paste-dispensing cannula (4) extending therefrom, provided with an inner longitudinal opening (8) connected, on the one hand, to the holder (1) and, on the other hand, to a nozzle (5) fixed on the end by means of which the toothpaste is dispensed onto a silk bristle brush head (2) located on the cannula and covering its nozzle, said head being provided with a hole (6) coming into contact with the nozzle. The device is essentially characterized in that: the cannula according to the end facing the holder comprises a rigid disk-shaped collar whose diameter is larger than that of the cannula; the holder is composed of a tubular flexible sheath, fixed by one of its ends to the collar; the length of said holder, whose capacity is limited to a single dose, is such that it can be pressed completely between the user's thumb and index finger. By using his thumb and index finger, the user causes the front part of the flexible sheath constituting the holder to be brought against the inner surface of the collar (7), such that the cannula is blocked axially in relation to the holder; and the brush head is fixed to the end of the cannula and is set aside from the collar (7) and hence from the holder at an interval sufficient so that it may be inserted between the jaw extremities without the holder being placed in the user's mouth.

Title: Lamination product for manufacture of identification card
Inventor: DROWER HERBERT M
IPC: B42D15/10
Filed: 1991-01-31
Granted: 1994-10-11
Abstract: A two-element lamination product for manufacture of a secure identification card that requires no insert comprises first and second resin lamination sheets, each substantially larger than the desired ID card dimensions, that are joined along one edge; the two sheets have engageable heat-and-pressure sealable surfaces and are precision cut to define two aligned, matching card panels of the desired ID card dimensions.  Each card panel is joined to its sheet by plural frangible bridges.  The first card panel has a transparent portion and the second an aligned, matching opaque portion with an image- receptive surface facing the first card panel; opacity may be obtained by pigmentation or by surface coating.  Usually, the entire first card panel is transparent and the second card panel is all opaque.  After ID image data is applied to the opaque part of the second card panel the sheets are sealed together and the sealed card panels are then broken out, affording a secure ID card that is very difficult to separate for alteration purposes.

Abstract: The disclosure is a technique to automatically generate AWK code from English text for monitoring text streams and executing actions when predefined patterns are matched.  The English to AWK Translator in ITM can translate English keywords and data into executable AWK programs.  Since text steams from a modem port can be monitored the same way as a file, it is possible to monitor telephone switches with the AWK programs generated by the Translator.  With an automated monitor system like the Interactive Text Monitor, telephony engineers will free themselves of expensive and boring babysitting sessions when they monitor switches looking for problems to occur.

IPC: C07C31/04
Filed: 1992-02-24
Granted: 1999-08-17
Abstract: Methanol is produced frog synthesis gas comprising hydrogen, carbon monoxide, and carbon dioxide in a two-stage liquid phase reactor system. Each reactor is operated in an optimum temperature range to maximize methanol productivity, and once-through product conversion of up to 9.1 moles methanol per 100 moles of synthesis gas can be achieved with reasonable catalyst utilization. Overall catalyst utilization is increased by countercurrent catalyst transfer. In an alternate mode of operation, the liquid phase reactor system is integrated with a coal gasification combined cycle (CGCC) power generation process wherein the unreacted synthesis gas is used as fuel in a gas turbine-driven electric power generator. Operation of each liquid phase reactor in the optimum temperature range maximizes the available heat of reaction which is recovered as steam; the steam is utilized in the gas turbine combustor or the CGCC steam turbine. Methanol from the liquid phase reactor system can be used as peak shaving fuel for the gas turbine.

Title: Split-window time-alignment
Inventor: BAECKSTROEM TOMAS
IPC: H04W56/00
Filed: 1992-02-27
Granted: 2001-02-06
Abstract: Synchronization is maintained between a regional radio transmitter/receiver and a remote transmitter/receiver communicating across a TDMA channel by detecting time misalignment of communications from the remote transmitter/receiver to the regional transmitter/receiver, commanding the remote transmitter/receiver to adjust its transmission timing, and, until the remote transmitter/receiver has adjusted its transmission timing, looking for a synchronization pattern accompanying transmissions by the remoter transmitter/receiver during two discontinuous time intervals, one centered about a time of occurrence of the synchronization pattern before the command and another centered about an expected time of occurrence of the synchronization pattern in response to the command.      Effectively, what would otherwise be a disadvantageously wide tune window is split into two advantageously narrow time windows to avoid detection of false syncs. Fewer false syncs are detected; and speech quality is increased.
