Title: Fiber suspension thickener having improved discharge consistency
Inventor: SMITH RYAN M
IPC: B01D33/073
Filed: 1996-04-30
Abstract: A fiber suspension thickener, particularly adapted for thickening cellulose fiber. The thickener comprises a vat (103); a hollow filter assembly in the form of a horizontal cylindrical drum (101) disposed within the vat (103), whereby the drum (101) may be rotated by a motor (152) around its horizontal axis (151), and whereby the circumferential walls of the drum (101) are made of a filter material (102); either a spray nozzle (106a) or some other supply conduit (106b) that furnishes a fibre suspension into the interior of the vat (103), so that the drum (101) becomes submerged within a pool (161) of the fiber suspension; a discharge outlet (110) for discharging the fiber suspension on the ascending side (102c) of the rotating drum (101); and a turbulence creating device (260) that can take many forms, e.g. projections (260a-d) or indentations on a weir (260g) positioned along the interior wall (103a) of the vat (103), a stationary member like a rod (260e) or a rotating screw mechanism (260f) attached to the end walls (103b) of the vat (103), for creating turbulence and mixing the fiber suspension on the ascending side of the rotating drum (101). The turbulence creating device (260) prevents coarse fibers within the fiber suspension from caking or matting on the exterior of the filter material (102) of the drum (101), and improves the overall thickening capability.

Title: Coolant filter having a delayed release supplemental coolant additive cartridge
Inventor: BROWN GENE W
IPC: B01D35/02
Filed: 1998-06-02
Abstract: A coolant filter for a diesel engine having a mechanism for delayed release of chemical additives into the coolant being filtered.  The present invention provides a spin-on canister type coolant filter which combines the functions of filtering the coolant of the diesel engine cooling system with the function of adding supplemental coolant additives to the coolant to reduce or eliminate the effects of cavitation erosion caused by vibration of the cylinder liners of the diesel engine. The filter includes a chemical additive cartridge mounted within an outer shell and a filter cartridge mounted about the chemical additive cartridge and inside the outer shell.  Coolant to be filtered passes by the chemical additive cartridge, which slowly releases the chemical additive into the passing coolant stream.  The coolant containing the chemical additive then passes through the filter to remove relatively large pieces of the chemical additive as well as other debris before exiting the filter for subsequent cooling of the diesel engine.  In order to slowly release the chemical additive, the chemical cartridge includes relatively small air vents and outlets and the filter outlet includes a restriction orifice which further slows the release of the chemical additive into the coolant stream.

Title: Alginate gel based adsorbents for heavy metal removal
Inventor: CHAE MYEONG YUN
IPC: C08B37/04
Filed: 1998-06-30
Abstract: An alginate gel adsorbent to remove heavy metal ions according to the present invention is prepared by adding dropwisely 0.1-5 wt % alginate solution to a polyvalent cationic solution thereby cross-linking alginic acid with polyvalent cations. An alginate gel adsorbent containing activated carbon capable of simultaneously removing heavy metal ions and organotoxic materials, that is, activated carbon/alginate gel adsorbent, is prepared by adding dropwisely a mixed solution of 0.1-10 wt % of alginate and 0.1 10 wt % of activated carbon powder to a polyvalent cationic solution thereby cross-linking alginic acid with polyvalent cations in order to immobilize polyvalent cation to alginic acid containing activated carbon. The polyvalent cationic solution is selected from the group consisting of calcium chloride (CaCl2), strontium chloride (SrCl2), barium chloride (BaCl2) and aluminium chloride (AlCl3). A flat board or a thin membrane coated alginate gel adsorbent can be prepared by coating alginate gels onto a supporter such as paper, wood plate and textile fabrics. The alginate gel adsorbent for water purification can be applied to a water purifier as well as a process of wastewater treatment. The alginate gel coated onto a supporter is prepared by immersing a supporter in 0.05-5 wt % alginate solution so that the supporter may uniformly adsorb the alginate solution, immersing the supporter in a polyvalent cationic solution thereby forming alginate gel on the surface of the supporter, and drying the supporter formed with alginate gel thereon.

Title: Retrofit lighting system that non-invasively interacts with a host machine
Inventor: CASSORLA EARL
IPC: H05B44/00
Filed: 1997-01-23
Abstract: A retrofit lighting system (100), for use with a host machine (104), produces lighting effects in response to lamp power signals that are provided from the host system (104) and that would otherwise be used to power lamps (108) of the host machine (104). An EL lamp system (108) has a plurality of EL lamp cells. Sequencing circuitry (106) provides an EL lamp driving signal to independently control each of the EL lamp cells of the EL lamp system (108) such that the EL lamp cells collectively illuminate in a sequence corresponding to the EL lamp driving signal. The microcontroller (406) controls the frequency, amplitude, and duty cycle to the electroluminescent lamps (108). By changing the frequency, the microcontroller (406) alters the intensity and illumination color. By changing the amplitude, the microcontroller (406) alters the illumination intensity. Further, data signal lines are supplied from the microcontroller (406) to select which electroluminescent lamps (108) to illuminate, thereby creating animated displays. Signal conditioning circuitry (102) non-invasively samples the lamp power signals provided from the host system (104), and provides the driving signal to the EL lamp (108) in response thereto.

Title: Alternating current hid lamp with magnetic deflection
Inventor: FLANAGAN ROBERT W JR
IPC: B60Q1/14
Filed: 1998-11-27
Abstract: A magnetic field controller has been developed, which allows magnetic deflection of the arc of an alternating current high intensity discharge (HID) lamp. The controller consists of a driving circuit and an electromagnet. The system delivers a fast switching magnetic field, which can follow the alternating current signal of an alternating current HID ballast. The method minimizes the electromagnet's inductance and uses fast reacting ferromagnetic materials (Ni-Zn ferrite). To achieve the required magnetic field, a current amplifier was developed to pick up the signal from the alternating current ballast and drive the electromagnet with up to two amperes. The alternating magnetically deflected HID lamp system allows the use of magnetic deflection for alternating current HID lamps. A vehicle headlamp system can achieve multiple beam functions (day light running, low beam and high beam) of a headlight system with only one alternating current lamp.

A master device resides on a first printed circuit board (PCB) and communicates with slave devices on a second PCB having more than one type of serial communication protocol. The translator resides on the same PCB as the slave devices thus requiring that only the serial buses corresponding to the master device protocol type to be physically coupled across the two PCB's interconnection interface.
