Title: A method for producing polybutylene terephthalate
Inventor: LIAW MING-JEA
IPC: C08G63/183
Filed: 1992-02-01
Granted: 1993-10-11
Abstract: A method for producing polybutylene terephthalate, comprising several steps: a. Mix butanediol, terephthalic acid, and catalysts in the reactor. The mole ratio of butanediol to terephthalic acid is 1.1-2.0. Catalysts include organotin and/or organotitanium compounds. Base solution is obtained by primary esterification reaction at 210-240xC under normal pressure. b. Two stage esterification reaction is carried out at 210-240xC under normal pressure or pressured condition. c. Transfer half amount of ester obtained from step b into step polycondensation reactor and react to higher polymerization degree until determined viscosity is reached. Products are cooled and chopped to pellets. The characteristic is repeating step b and c until batch typesemi-continuous polycondensation reaction is completed. Two stages reactions in step b include: First stage: Add terephthalic acid, butanediol, catalysts and water to the base solution and esterfication reaction is carried out. The amount of terephthalic acid is the same as that in step a. The mole ratio of butanediol to terephthalic acid is between 1:0.7 and 1:1.4. The amount of water isn't higher than 35 wt% of butanediol. Second stage: Add butanediol one time or several times to the reactor and ensure that esterification reaction is completed. The mole ratio of butanediol added in this step to terephthalic acid added in first stage is higher than 0.35.

Title: Shunted connector assembly and shunt assembly therefor
Inventor: BENJAMIN HOWARD MOSSER III
IPC: H01R29/00
Filed: 1993-07-16
Granted: 1994-01-11
Abstract: A shunted connector assembly wherein the electrical connector has a housing with spaced contacts, each having an exposed contact portion along an open portion of a side wall of the housing. A shell member is mounted to the connector housing and a shunt contact support housing is slidably mounted to the shell member. The shunt contact support housing is movable generally linearly between first and second positions. When the shunt contact support housing is in the first position, shunt contacts secured therein engage pairs of spaced contacts of the connector. When the shunt contact support housing is in the second position, the shunt contacts are electrically isolated from the connector contacts. A spring biases the shunt contact support housing toward its first position so that when the connector is disengaged from a mating receptacle connector, the shunt contact support housing is automatically moved to the first position in which connector contact pairs are electrically commoned. When the electrical connector is mated with a receptacle connector, the shunt contact support housing comes into interfering engagement with structure surrounding the recess of the receptacle connector so that the shunt contact support housing is moved to the second position. During movement of the shunt contact support housing from its first position toward its second position, it is lifted away from the electrical connector so that the shunt contacts do not rub against the connector.
