Title: Catalyst system for polymerization of 1,3-butadiene to trans-1,4-polybutadiene
Inventor: PATTERSON DENNIS B
IPC: C08F4/48
Filed: 1991-02-19
Abstract: Abstract of the Disclosure CATALYST SYSTEM FOR POLYMERIZATION OF 1,3-BUTADIENE TO TRANS-1,4-POLYBUTADIENE     Trans-1,4-polybutadiene is a thermoplastic resin rather than a rubber at room temperature by virtue of its high degree of crystallinity.  Because trans-1,4-polybutadiene contains many double bonds in its backbone, it can be blended and cocured with rubbers. It is accordingly an attractive alternative to conventional fillers such as carbon black, which are typically utilized in compounding rubber.  By utilizing the catalyst system and techniques of this invention, trans-1,4-polybutadiene can be synthesized at a high level of conversion.  This invention specifically relates to a process for the synthesis of trans-1,4-polybutadiene by an anionic polymerization process which comprises:  (a) adding an organolithium compound and an alkali metal alkoxide as a catalyst system to a polymerization medium containing 1,3-butadiene monomer and an organic solvent; and (b) allowing the 1,3-butadiene monomer to polymerize at a temperature which is within the range of about -10°C to about 45°C to produce the trans-1,4-polybutadiene.

Title: Shower head
Inventor: GENTRY JEFFERSON L
IPC: B26B21/40
Filed: 1991-03-28
Abstract: ABSTRACT OF THE DISCLOSURE             A shower shaver is made from two plastic piece parts.  A first part is a handle in the nature of a pipe terminating in a cavity.  The other piece part delivers water which strikes a razor blade and then exits under the cutting edge of the blade with enough force to wash debris away from the blade.   A valve on the shaver handle provides a continuously variable control over the flow of water to the shaver.  A tubing or hose attached to the shower shaver leads to a nipple which may be interposed between an outlet and a pipe.  A quick disconnect connector enables the tubing to be connected to or disconnected from the nipple.  A bracket or hanger is attached to a wall in any suitable out of the way location in order to receive and support the shaver when the shaver and the quick disconnect connector on the tubing is not in use.
