A phase locked loop including a flying-adder divider circuit configured to receive phases of a periodic signal from a frequency generator and output a feedback signal to a phase detector, and a method of generating a periodic signal using such a flying-adder circuit, are disclosed. The flying-adder divider circuit generally includes a flying-adder and one or two divide-by-N dividers. The flying-adder receives K phases of the periodic signal, where K is an integer of at least 2, and generates a divided periodic signal from the K phases. The phase locked loop may include flying-adder divider circuits inside and/or outside the loop.

A chewing gum with a liquid-fill composition and a surrounding gum region, with one or both containing active ingredients, such as herbal, medicinal and/or mineral elements or combinations thereof, present in an amount of at least about 0.05 mg.

A magnetic blade retainer for an expandable broadhead utilizing the properties of magnetic attraction to reliably secure a plurality of blades completely within respective blade channels so that an expandable broadhead may closely resemble the flight properties of a practice arrow tip yet lethally expand upon impact with a target. Extraneous parts are eliminated, but a strong, disc magnet is inset or integrated into the forward portion of a broadhead tip assembly. Each blade is provided with a magnetic, flat forward end. The interaction of the flat forward end and the magnet magnetically retain each blade. The magnetic bond is broken when the arrow penetrates a target. An actuating spike further transfers the impact energy to each blade. The forces on the actuating spike then drag each blade backward and each blade extends as the rearward forces are translated by the wedging surface near the end of the channel.

Methods and devices are provided for an agricultural pesticide-free air sterilization machine. In one embodiment, the machine employs a liquid-gas mixing device, an ozone generator, a water inlet; and/or a water outlet. The mixing device may have a water inlet, a water outlet, a feed pump, a jet device, and/or a liquid-gas mixer. Further, the ozone generator utilizes an oxygen generator, an oxygen storage container, and a high voltage discharge chamber. In other embodiments, the feed pump is connected to the water inlet of the jet device via a hose, and the ozone generator is connected to the gas inlet of the jet device via a gas tube.

An energy recovery system includes an exhaust line which is capable of collecting exhaust gas from an exhaust manifold of the engine and which is equipped with a particulate filter, a secondary line which is thermally linked with, but distinct from, the exhaust line, and which carries a fluid. The particulate filter has a filtering part in which exhaust gases can flow and a heat exchanging part in which the fluid can flow, the filtering part and heat exchanging part being arranged to transfer heat by conduction from the exhaust gases to said fluid. The secondary line is connected to energy recovery means capable of recovering energy from the heat.

The VEA Detector and Dynamic Range Controller of the invention more accurately measure constant or non-constant, periodic or aperiodic, signals and the use of such measurements to control the upstream and/or downstream processing of program signals, including without limitation audio, video, and power program signals. The invention uses an antilog module acting within the context of a log domain circuit such that the “averaging” at an integrator is linear, not logarithmic. However, since the detection is within the log domain, the dynamic range of the VEA Detector is exponentially larger.

The invention is an apparatus and method to allow a microcontroller unit with fewer pins to use SDRAM. This invention uses the SDRAM burst mode in a favorable way. On an initial cycle of the burst access the microcontroller supplies an address one less than the actual initial address on a multiplexed address/data bus connected to both the address bus and the data bus of the SDRAM. DQM signals from the microcontroller to the SDRAM suppress all data writes. On the second and subsequent cycles of the burst assess, the microcontroller supplies the next data word to be written on the multiplexed address/data bus together with DQM signals permitting data writing. This technique prevents collisions of address and data on the microcontroller multiplexed address/data bus.

A polymer comprising a polymer backbone. The polymer backbone has a plurality of carbon atoms. There are two lipophobic carboxylate groups or carboxylic acid groups per repeating unit being coupled to separate carbon atoms of the backbone. The polymer may be used to recover metals by chelation and then burning away the polymer.

A pH treatment and method for extraction of leachable resources and pollutants from sludge. A volume of wastewater sludge is initially dewatered followed by adding pH adjusting agents to the dewatered sludge to remove acid/base-soluble contaminants. The acid/base-soluble contaminants are flushed out or dewatered from the treated product. Treated sludge can then be sent to storage and held for beneficial uses.

A method for operating a dual-fuel internal combustion engine, having an intake path and an engine having a number of cylinders. In the method the engine is operated in a first operating state in diesel operation with diesel or another liquid fuel, and in a second operating state in gas operation with gas as fuel in a charge mixture, and switching between diesel operation and gas operation takes place in a switchover range determined, in particular predetermined, by switchover operating parameters.

Disclosed is a ceramic sintered shaped body containing Y₂O₃-stabilized zirconia with a sintered density of at least 99% of the theoretical sintered density and having a mean grain size of <180 nm. The zirconia fraction of the sintered shaped body comprises tetragonal and cubic phases. Also disclosed is a process for the production of a ceramic sintered shaped body containing Y₂O₃-stabilized zirconia, which process comprises dispersion of a submicron powder and comminution of the dispersed submicron powder by means of grinding media having a diameter of less than or equal to 100 μm to a particle size d₉₅ of <0.42 μm; shaping of the dispersion to form a body, and sintering of the body to form the sintered shaped body.

According to the invention there is provided a tertiary effluent treatment process for reducing the phosphate levels in effluent. The process comprises the steps of delivering effluent from a wastewater treatment plant to a primary filter, delivering the filtered effluent to a series of two or more phosphate removal filters, delivering the filtered phosphate-depleted effluent to a treated water tank as treated water, delivering the filtered phosphate-depleted effluent from the treated water tank to a discharge tank as treated water; and, discharging the treated water from the discharge tank as required. Each phosphate removal filter comprises a plurality of polymer-based beads having nano-particles of iron oxide coated thereon. The advantage of using a series of two or more phosphate removal filters is that the process can deliver a final effluent containing specific pre-determined levels of phosphate that may be as low as 0.01 mg/L of effluent, but will in all cases be below 1 mg/L. The series of two or more filters also allow the process to accommodate variations in the phosphate content of the effluent without affecting the level of phosphate in the discharge, and, the system can be retro-fit to the end of any type of existing waste water treatment plant or can be integrated into a new facility.
