Title: System for removing nutrients from wastewater
Inventor: SCHMID LAWRENCE A
IPC: C02F3/30
Filed: 1997-01-29
Abstract: A wastewater treatment system mixes return activated sludge with influent wastewater under anoxic conditions (42) in the presence of luxury uptake microorganisms to cause release of phosphorous compounds into the wastewater. The wastewater is then aerated (44) in the presence of nitrifying microorganisms to convert ammonia into nitrate while the luxury uptake microorganisms take up the phosphorous compounds. The wastewater is then subjected to alternating anoxic and oxic conditions (46a, 46b) to reduce the nitrate to nitrogen gas using denitrifying microorganisms. The resulting effluent is substantially free of nitrogen based and phosphorous based nutrients.

Title: Cross training exercise device
Inventor: WHAN-TONG JANINE
IPC: A63B21/22
Filed: 1998-11-10
Abstract: An exercise device includes a pair of foot engaging links (30a, 30b). The rearward ends of the foot links are supported by a coupling system (100, 102, 104, 110) for arcuate motion about a closed path of travel, and the forward ends of the foot links travel back and forth along a guide (36). The combination of these two foot link motions permits the users feet to travel along an elliptical path of travel. The inclination or elevation of the guide may be selectively altered to vary inclination of the foot links which in turn changes the nature of the stepping motion experienced by the user. At flatter inclinations of the foot links, the stepping motion may resemble cross country skiing. At progressively greater angles of inclination of the foot links, the stepping motions may simulate walking, jogging, running and climbing. Also, the coupling system may be adjustable to change the length of the closed path of travel of the rear ends of the foot links.

IPC: H01H35/14
Filed: 1998-12-02
Abstract: The present invention provides an alarm for detecting the unauthorized movement of an object said alarm comprising a motion detection means and an audible alarm means. The motion detection means comprises a series of radially extending electrical contacts together with a peripheral electrical contact ring that encircles the perimeter of the outside edges of the radially extending electrical contacts. A metallic ball is provided within the electrical contact ring and is of sufficient size that it can roll freely within the interior of the ring. When the object to which the motion detection means is attached is stationary, the ball will tend to come to rest in a position against the contact ring while touching one or more of the radially extending contacts to form an electrical circuit. Means to detect when an electrical circuit is formed by the contact ring, ball and any radially extending contact and to detect when this circuit is broken by movement of the object. The means to detect when an electrical circuit is formed or broken preferably consists of a programmable control microprocessor and input means for programming said processor. The alarm can be attached to valuable items such as televisions, stereo systems, VCR's, video cameras, computers etc. When the alarm is armed it will sense any motion of the item to which it is attached and will sound an alarm if sufficient motion has been detected.

Inventor: NAIZY R RICHARD
IPC: C09J7/02
Filed: 1997-06-16
Abstract: A decorative film (10), such as a film of pigmented paint (12) or other coating covered by a film of clear coat (14), has the outer (clear coat) surface protected by a removably fixed thermoformable first protective film layer (16). A flexible plastic film forming a second protective layer (18) is removably fixed to the first layer (16). The underlying paint film (12) may be laminated to a thin wall or thick wall thermoplastic formable sheet (22). The second protective layer (18) is removed just prior to forming of the paint film (12) or laminated decorative sheet (10), carrying with the protective film (16) any surface damage marks or irregularities. Subsequent compression forming, as into a body panel or trim part, thus will not cause marking of the paint film (12) from transfer of damage marks since the underlying first protective layer (16) remains undamaged. The first protective layer (16) may remain in place during assembly of the formed body panel or trim part (20, 24) into a vehicle, and thereafter until delivery of the vehicle by a dealer to a customer. The second layer (18) may act as a carrier for the films and is stripped from the first protective layer (16) before forming, so it may be made from non formable material such as PET polyester.

Abstract: A vehicle for the collection, compacting and unloading of source-separated recyclables. The trailer box of the vehicle is longitudinally divided into three internal compartments, each of which has a compacting packer blade which is also utilized to unload the collected recyclables from the vehicle. Loading is accomplished by lifting and inverting a recyclables collection bin, having three internal compartments similar to the trailer box internal compartments, over the hopper portions of the trailer box internal compartments. Separated recyclables are guided during dumping by hinged bin lids which facilitate communication between the internal compartments of the bin and trailer box. Alternatively, an open-front adapter bin capable of containing recyclables tote containers may be used in the place the above-described recyclables collection bin. The collected recyclables are vertically compacted by a movable hopper top cover and horizontally compacted by the packer blades. Unloading is accomplished in one trailer box internal compartment independently of the others by fully moving the packer blade contained therein the length of that internal compartment while simultaneously opening one of three upwardly lifting rear unloading doors.
