Title: Dispenser can cooler
Inventor: RENAUD ROBERT E E
IPC: B65D83/00
Filed: 1990-02-21
Abstract: Recommended Forms Form 24 (ss.21,31,34 and 142) ABSTRACT It is Known that the primary function of can coolers is to store and keep cool cans in a portable and easily accessable fashion. In this invention the process of storage and retrievability is simplified. The shape of the can cooler is tall with a wide base, and acts in the capacity of a dispenser. The coolers cooling ability is enhanced, with the majority of the cans physically coming in contact with the cooling agents (ie.ice packs). The cooler is designed such that cans are entered from the top in a track, and then dispensed from the bottom. The coolers backside is curved such that it may be used as a backpack cooler. There are a total of four (4) indentations with bars, each presiding in a corner area of the coolers backside, allowing for the attachment of straps. This will enable the user to carry the cooler as a backpack or secure the cooler to objects. The can cooler contains a removable lid with two (2) circular impressions on the exterior of the lid for the placement of cans during recreational use, and a locking handle mechanism which locks in place the removable lid.

Filed: 1991-01-21
Abstract: A vibration damping device of the bushing-type includes a rigid outer housing and a rigid inner member, having a first side and a second side, which is substantially enclosed by the outer housing.   A first vibration absorbing resilient body is inter-posed between the first side of the inner member and the outer housing.   The  first body is made of an elastomeric material having  a  first  spring  rate.    A  second  vibration  absorbing resilient body is interposed between the second side of the inner member and the outer housing.   The second body is made of an elastomeric  material  having  a  second  spring  rate  which  is different from the first spring rate such that a deflection of the rigid inner member toward one of the first and second bodies will be resisted more strongly than a deflection of the rigid inner member toward the other of the first and second bodies.  A first fluid chamber is defined in the second body and a second fluid chamber is defined between the second body and the outer housing.  The second fluid chamber is in fluid communication with the first chamber through a first fluid passageway.  A plate is moveably   mounted   in   the  first  passageway   for  movement perpendicular to a longitudinal axis of the device.   The plate controls  a  flow of  fluid through  the  first passageway to a varying extent depending upon the position of the plate in the first passageway.   A second fluid passageway communicates with the first and second fluid chambers through a circuitous path.

Title: Method for purification of ibuprofen comprising mixtures
Inventor: ZEY EDWARD G
IPC: C07C51/43
Filed: 1991-09-05
Abstract: This invention pertains to a method of purifying ibuprofen-comprising reaction product mixtures. The method of purification is based on crystallization of ibuprofen from a hydrocarbon solvent and the discovery that there are impurity complexes in the ibuprofen-comprising reaction product mixtures which cannot be removed by crystallization from a hydrocarbon solvent.      The method of the invention includes at least one step in which the impurity complex in a first ibuprofen-comprising mixture is destabilized or broken up, followed by crystallization of the ibuprofen from a second solution or mixture comprising the first ibuprofen-comprising mixture, whereby the impurities which were previously complexed can than be removed from the ibuprofen by the crystallization of ibuprofen from a solvent.
