Title: A biodegradable polyethylene composition chemically bonded with starch and a process for preparing thereof
Inventor: YOO YONG-DEUK
IPC: C08F255/02
Filed: 1993-11-22
Abstract: ABSTRACT   The present invention relates to a biodegradable film prepared by chemical bonding of starch and polyethylene chains using polyethylene which is polyolefin having the most widest general application, coupling agent such as maleic anhydride, methacrylic anhydride or maleimide which bonds with starch and polyethylene, and acid catalytic comonomer like acrylic acid and/or methacrylic acid and to a process for preparing thereof.   The present invention was accomplished varying coupling agent such as maleic anhydride, methacrylic anhydride or maleimide at an amount of 0.01-10 weight%, acid catalytic comonomer such as acrylic acid and/or methacrylic acid at an amount of 0.01-10  weight% and radical initiator at an amount of 0.01 1.0  weight% based on the amount of polyethylene, and the reactive extrusion was appelied to lower the production cost by process simplification.   There was no difference in tensile strength and tensile elongation of the prepared biodegradable films comprising up to 20 wt.% of starch in comparison with the base resin by Instron measurement.     The facts that ester bond showing chemical bonding between starch and matrix resin was found on the infrared absorption spectrum and the phenomenons that the boundary between matrix resin and starch particle is unclear, and the starch particle is cross-sectionally cut are shown on the cross-section of films with scanning electron microscope approving  chemical  bonding between starch and matrix. The biodegradability was the most excellent with more than 10 wt. % of starch.

Inventor: GROPPER DANIEL R
IPC: G08B21/10
Filed: 1995-03-06
Abstract: This invention relates to an automatic, emergency or weather alert interface system between a first communication system, on which an emergency alert signaling tone is transmitted to indicate the occurrence of an emergency condition, and a second communication system, different from the first communication system. In operation, an emergency alert signaling tone is received from the first communication system by the emergency alert interface system which causes a prerecorded alert message to automatically be transmitted on the second communication system for an adjustable number of cycles wherein the audio from the prerecorded alert message is mixed with the audio from the second communication system so as to permit both audio messages to simultaneously be transmitted on the second communication system.          Additional features taught herein include the transmission of a subaudible signaling tone on the second communication system to permit listeners on the second communication system to filter out all non emergency communication on that system until the subaudible signal is transmitted and the ability to permit a second communication system listener to access and link the first communication system to the second communication system to permit immediate access to the alert message on the first communication system through the second communication system.

Abstract: A miniature scan engine module for bar code reading and data collection systems utilizes a light source (44) and a light collector (42), which in one embodiment are flexurally supported on a platform (62) which reciprocates (88) on pivots defined by flexures (96). The optical collector faces the bar code and pivots with the scanning beam source (a laser diode). A diffraction grating or Fresnel lens on the surface of the optical collector which faces the code directs the incoming light so that it propagates internally in a substrate within the body of the collector, i.e. in the optic itself and without air paths which require addition volume in the module, to a photodetector (68). The scan engine can be configured so that it occupies a volume of less than 1 cubic inch. A data collection system, in the form of a portable terminal, has a housing which provides a handle (12) and a receptacle (18) for a terminal unit (14) which is separable from the housing.

Title: Method of hatching avian eggs
Inventor: FERGUSON MARK WILLIAM JAMES
IPC: A01K41/00
Filed: 1993-12-16
Abstract: A method of hatching eggs of avian species, especially chickens, which comprises carrying out at least one cycle of steps (a) to (c) as follows: (a) incubating the eggs in a first, baseline ambient environment which is normal for hatchery incubation of the eggs of the avian species in the prevailing climatic conditions and then during a sex-sensitive time window of embryonic development, (b) altering the ambient environment to shifted conditions for a period of time effective to bias the normal phenotypic sex ratio of the embryos, without significant adverse effect on the average mortality rate, and (c) thereafter restoring the incubation conditions to or towards normal and allowing the eggs to hatch. Preferably the ambient environment comprises a temperature of 37.5-38 °C and the shifted conditions comprise reduced temperature, especially a temperature maintained at about 22 °C for a period of from 18 to 42 hours. The method may be used to produce birds which are chromosomally male (ZZ) but phenotypically female or chromosomally female (ZW) but phenotypically male.
