摘要:
The present invention provides a method and apparatus for dispensing a predetermined fixed amount of pre-stretched packaging material based upon load girth. A non-rotating ring carries a belt driven by a motor. A packaging material dispenser is mounted on a rotating ring, and the rotating ring may include a pulley that connects to the band, such that the rotating ring is driven by the drive belt. Based upon the girth of the load to be wrapped, an amount of pre-stretched packaging material to be dispensed for each revolution made by the rotating ring is determined. Good wrapping performance in terms of load containment (wrap force) and optimum packaging material use is obtained by dispensing a length of pre-stretched packaging material that is between approximately 90% and approximately 120% of load girth. Once the amount of packaging material to be dispensed per revolution is determined, a ratio of rotating ring drive to final pre-stretch surface speed (i.e., number of pre-stretch roller revolution/rotating ring rotation) can be set and mechanically controlled. Thus, for each revolution of the rotating ring and dispenser, a predetermined fixed amount of packaging material is dispensed and wrapped around the load. In an alternative embodiment, the ratio is electronically controlled.
摘要:
A hybrid optical component that collects and concentrates incident light. The hybrid component includes both refractive and reflective elements. In preferred embodiments, refractive and reflective components focus rays on a common focal plane generally located at the bottom of the reflector where they are absorbed by a device such as a photovoltaic (solar) cell. Additionally, the optical component combines both imaging and non-imaging optical elements into a single device, for improved overall performance.

摘要:
A method for interoperable communications including at least the step of: a) at least one radio user's being able to transmit at least one transmission on a first radio frequency to a computer having at least one sound card and at least two sound card channels on one or more sound cards, wherein each of the at least two sound card channels is programmed to receive and process transmissions from at least two separate radio frequencies. This configuration creates a new way of interfacing virtually any speaker with virtually any computer, and allows a paradigm shift of communications organization such that everyone can talk at once, literally, and still “hear” everyone else.

An input stage for an integrated circuit device provides constant gain in selectable modes of either differential or single-ended operation. In one embodiment, transconductance devices are arranged so that the input impedance of the input stage matches the signal source impedance, regardless whether the input stage is selected to operate in a differential mode or in a single-ended mode. In accordance with an alternative embodiment, constant-gain and constant-impedance conditions are maintained in a configuration that comprises and input signal attenuator. In one application, the input stage may serve as a low-noise amplifier (LNA) for an integrated transceiver.

The passage of a container along a conveyor is lubricated by applying to the container or conveyor a lubricant composition comprising a water-miscible silicone material having a silicone emulsion wherein the silicone emulsion contains less than 500 ppm of a triethanolamine salts of alkyl benzene sulfonic acid compounds.
摘要:
A method and apparatus for forecasting the likely occurrence of convective weather events, such as thunderstorms. An image filter is used to identify areas of interest within a meteorological image that are likely to contain convective weather. The image filter and an image difference processor identify sub-image regions within the meteorological image that are likely to experience a growth and/or decay of weather events. The classification filter classifies sub-image regions within the meteorological image into a number of predetermined storm categories. The meteorological images are filtered using matched filters, features within the filtered images are tracked, and the resulting track vectors are combined according to the storm classification. The meteorological image, interest image, growth/decay image, classification image, and combined vectors are processed to produce the short-term forecast.
摘要:
Disclosed is a third stage separator which includes two main clean gas outlets. One main clean gas outlet communicates with a power recovery unit such as an expander turbine while the second main clean gas outlet communicates with a conduit that bypasses the expander turbine. The present invention avoids use of the extra equipment, engineering and installation labor required to prevent the bypass conduit from placing a force load on the line to the power recovery unit.
