Given that $U=R$, the solution set of the inequality $ax^{2}+2x+b > 0(a\neq 0)$ with respect to $x$ is $\{x|x\neq - \frac {1}{a},x\in R\}$, and $a > b$. Let $t= \frac {a^{2}+b^{2}}{a-b}$, find the range of real number $t$. Also, let set $B=\{m||x+1|-|x-3|\leqslant m^{2}-3m,x\in R\}$ always holds true, find $A\cap(\lnot_{U}B)=$ \_\_\_\_\_\_.
