摘要:
A process for the production of 4-hydroxybutyraldehyde is described. The process comprises reacting allyl alcohol with a mixture of carbon monoxide and hydrogen in the presence of a solvent and a catalyst system comprising a rhodium complex and a trans-1,2-bis(bis(3,5-di-n-alkylphenyl)phosphinomethyl)-cyclobutane. The process gives high yield of 4-hydroxybutyraldehyde compared to 3-hydroxy-2-methylpropionaldehyde.

A bill dispenser includes a cantilever and traction wheel attached thereto. The wheel includes a traction surface around a perimeter thereof for frictionally engaging a currency bill. Movement of the traction surface atop the bill is used for dispensing the bill from its bin.
摘要:
A direct hydrocarbonylation process for the production of 1,4-butanediol is described. The process comprises reacting allyl alcohol with carbon monoxide and hydrogen in an alcohol solvent in the presence of a catalyst system comprising a rhodium complex, a trialkyl phosphine, and a diphosphine. The process gives a high yield of 1,4-butanediol in a one-step reaction.

A process for the production of 4-hydroxybutyraldehyde is described. The process comprises reacting allyl alcohol with a mixture of carbon monoxide and hydrogen in the presence of a solvent and a catalyst system comprising a rhodium complex and a 2,3-O-isopropylidene-2,3-dihydroxy-1,4-bis[bis(3,5-di-n-alkylphenyl)phosphino]butane. The process gives high yield of 4-hydroxybutyraldehyde compared to 3-hydroxy-2-methylpropionaldehyde.
摘要:
A method of managing time-sensitive items which relies on identification information of RFID labels associated with the items. The method includes the steps of identifying the time-sensitive item, and obtaining the expiration information from a web site of a seller of the time-sensitive item. In another form concerned with products, the method includes the steps of identifying an EPL associated with the product, causing the EPL to interrogate an RFID label on the product, receiving identification information from the RFID label, and obtaining the expiration information about the product using the identification information from the RFID label. The method additionally compares the expiration information with current date information and either causes the EPL to display a lower price or assists with removal of expired instances of a product through a report.

摘要:
Techniques for activating a voice recognition system are described. The system disclosed can be non verbally started and stopped without the need for the system user to use his or her hands facilitating hands-free operation in an environment with a relatively high degree of ambient background verbal noise. For example, a user may start the voice recognition system by blowing once on a microphone and stop the system by blowing twice on a microphone. The user may alternately start and stop the system by using other nonverbal inputs such as facial expressions, clearing the throat or moving one's head. Such other nonverbal inputs may be detected by pressure sensors or motion sensors. The operational state of the system may alternately be toggled from off to on, or from on to off, with each subsequent nonverbal input.
