Abstract: A process for interpolymerizing a vinyl aromatic hydrocarbon polymer and a block polymer is disclosed. The process includes the following steps: a) forming a block polymer precursor of at least one polymeric block containing conjugated diene monomer contributed units in the presence of an anionic initiator and in an inert diluent, the block polymer precursor having living ends; (b) thereafter adding to the block polymer precursor a charge of a vinyl aromatic hydrocarbon monomer and an additional charge of an anionic initiator to simultaneously form (1) a block polymer having a terminal block formed from the charge of vinyl aromatic hydrocarbon monomer attached to the block polymer precursor and (2) a poly(vinyl aromatic hydrocarbon) polymer interpolymerized with the block polymer. The practice of this process produces a vinyl aromatic hydrocarbon block terminated block polymer, such as SBS, interpolymerized with a polymer formed from vinyl aromatic hydrocarbon monomer, such as polystyrene. The resultant interpolymer has a high Gardner Impact strength and good processibility.

Patent CA-2171543-A1 (CA)
Title: Brake for Pressureless Exit Channel, Coin Sorter
Inventor: JONES JOHN E
IPC: G07D3/12
Filed: 1994-09-13
Abstract: The present invention is a coin sorter apparatus for sorting a group of mixed coins by denomination and immediately terminating the sorting process in response to a predetermined operating condition, such as the filing of a coin receptacle with a predetermined number of coins. Sorting is provided by a stationary sorting head and a rotatable disc positioned sufficiently proximate to one another so that when the group of mixed coins are dropped into the center opening of the stationary sorting head, they are rotated by the rotating disc and guided by the sorting head on an outward spiral sorting path to exit channels along the periphery of the stationary sorting head.  Each of the exit channels acts as an exit chute for a particular coin denomination by releasing pressure on that particular coin and freeing the coin to move outwardly along the exit channel and exit in to a coin receptacle.  At the moment of the predetermined operating condition, a braking mechanism immediately stops the rotation of the rotatable disc, and the coins within an exit channel exit through the exit channel due to the inertia of the coins.
