Inhibit or Deactivate Plant Enzymes

An organization wants to deactivate or otherwise interfere with the action of enzymes pectin methylesterase and polygalacturonase, which interfere with the processing of certain fruits by degrading fruit pectins. Initial processing of the whole fruit releases the enzymes and release continues during further processing. The release of the enzymes decreases the thickening power of the fruit solids. By deactivating the enzymes, especially without using heat, more of the fruit solids thickening power may be conserved during processing. Greater retention of pectin in its natural state may also provide added benefits in serum binding and overall consumer acceptance.

Low-Energy-Curing Technology

A company seeks new and/or advanced curing technologies to incorporate into metal packaging protective coating and decoration processes. Systems could include metal containers for aerosols, beverages, food products, and specialty packaging, all of which require external and/or internal protective coatings. Process improvement may be obtained by upgrading the efficiency of the existing thermal curing gas ovens or introducing new coating materials that can be cured more efficiently using the existing ovens.

Cost-Effective Wind Turbine Generator

The Cutcher Wind Turbine Generator provides low- and no-cost power by utilizing tall structures such as rural and urban homes, as well as businesses and buildings. Unlike traditional wind-power generators, the Cutcher Wind Turbine Generator utilizes the wind current that is channeled around buildings and tall structures, eliminating the building of an additional tower for a platform. The generator utilizes wind-driven blades arranged around a hub. As the wind blows, the blades and hub begin to turn, the mechanical drive is activated, and it initiates the electric generator. The generator can be constructed from high-grade aluminum and is scalable to fit specifications for use in both industrial and consumer applications. It is engineered and designed with a box-like frame that employs wind-blocking walls that prevent the wind currents from blowing the blades in the reverse direction. The generator can be installed on existing buildings and structures such as homes, barns, grain elevators, office buildings, and oil tanks.

Method of Driving a Field Emission Display

This technology makes possible Field Emission Displays (FEDs) and Surface-conduction Electron-emitter Displays (SEDs) that can use a variety of less expensive cathode materials and types. The technology adjusts the output of the cathodes by using a monitoring circuit between the cathode and the anode (the visible phosphors), overcoming the poor picture quality that can result from emitters operating at different levels of effectiveness. With this technology, almost any kind of cathodes can be used in making display panels that have image quality as good as display panels made from carbon nanotube (CNT) cathodes, thus reducing manufacturing costs.

Gel That Changes Color on Demand Could Lead to New Sensors

Researchers at the Massachusetts Institute of Technology (MIT) have created a new structured gel that can rapidly change color in response to a variety of stimuli, including temperature, pressure, salt concentration, and humidity. The gel could be used as a fast and inexpensive chemical sensor. These environmental sensors could be used in food processing plants, where it would indicate if food that must remain dry has been exposed to high levels of humidity.

MV1000 and MV2000

Yokogawa Electric Corp., Newnan, GA, has introduced the MV1000 and MV2000 paperless portable recorders with integrated display, recording, and communications functions. The units record on-site changes in temperature, voltage, current, flow, and pressure. The MV1000 features 24 input channels; the MV2000 has 48 channels. Both units feature 200 MB of memory, allowing data to be stored for approximately 70 days at one-second intervals with a 12-channel model. The recorders feature guidance messages for set-up and entering of settings. Measured data can be stored in text format on removable storage media for further processing and data backup on a personal computer using standard software. The MV1000 features a 5.5" color TFT-LCD display; the MV2000 has a 10.4" display. For Free Info .
