Assignee:

Union Carbide Chemicals Plastics Technology Corporation - Danbury CT

International Classification:

C08G 6308

US Classification:

528354, 528355, 528357, 428480, 428338, 428339

Abstract:

Lactone copolymers are disclosed which are polymerized from a first lactone monomer and a second amorphous monomer which is effective to suppress the crystallization of the copolymer. It is disclosed that suppression of the crystallization can provide enhanced mechanical properties in films made from the copolymers. As a result, films prepared from the copolymers of the present invention can have properties rendering them suitable for use as biodegradable trash bags as well as for other uses.

Abstract:

A server in a network gathers textual information, such as news items, E-mail and the like. From that information, the server develops or identifies messages for use by individual subscribers. The same server that accumulates the text messages or another server in the network converts the textual information in each message to a sequence of speech synthesizer instructions. The converted messages, containing the sequences of speech synthesizer instructions, are transmitted to each identified subscriber's terminal device. A synthesizer in the terminal generates an audio waveform signal, representing the speech information, in response to the instructions. In the preferred embodiment, the terminals utilize concatenative type speech synthesizers, each of which has an associated vocabulary of stored fundamental sound samples. The instructions identify the sound samples, in order. The instructions also provide parameters for controlling characteristics of the signal generated during waveform synthesis for each sound sample in each sequence.

International Classification:

C08G 6902
C08G 6308

US Classification:

528310

Abstract:

Condensation copolymers are disclosed which are polymerized from a first monomer which is capable of polymerization by condensation polymerization, e. g. , ring opening lactone polymerization, and a second monomer which is effective to suppress the crystallization of the copolymer. It is disclosed that suppression of the crystallization can provide enhanced mechanical properties in films made from the copolymers. As a result, films prepared from the copolymers of the present invention can have properties rendering them suitable for use as biodegradable trash bags as well as for other uses.

International Classification:

G01N 30/28

Abstract:

Described is a metering pump that may be used to meter volumes of sample in a chromatography system. The metering pump has a modular configuration that allows for separation of a head pod from a drive assembly for easy serviceability. The head pod includes a pump head, cartridge housing, seal wash housing and plunger. The drive assembly can be implemented in an inline drive configuration. Alternatively, the drive assembly can be implemented in an offset drive configuration in which a stepper motor is displaced laterally from other drive assembly components but is coupled through a belt and pulley system.

Abstract:

An inductive power system including an inductive power transmitter coupled to a non-conductive medium, and a power cord that electrically couples the transmitter to an AC power source. The inductive power transmitter is configured to emit an electromagnetic field based on the received AC power. There is an inductive power receiver coupled to the non-conductive medium and separated from the transmitter, wherein the receiver is configured to receive the electromagnetic field after it has passed through the non-conductive medium and in response develop power. A power cord electrically couples the developed power to a power sink.
