Here's the first formula for which there is a problem:
\begin{equation}
\left\langle \begin{matrix}\overline{{B_{1}\;\subseteq\; C\left(B_{1}\;\cup\; B_{2}\;\cup\; B_{3}\right)}}\;\forall B_{3}\\
\vee\\
\left\{ \begin{matrix}\left[B_{1}\;\subseteq\; C\left(B_{1}\;\cup\; B_{2}\;\cup\; B_{4}\right)\right]\\
\vee\\
\overline{{B_{2}\;\subseteq\; C\left(B_{1}\;\cup\; B_{2}\;\cup\; B_{4}\right)}}\end{matrix}\right\} \forall B_{4}\end{matrix}\right\rangle \forall\left(B_{1},B_{2}\right)
\end{equation}

These formulae aren't generally equations, and restating them to reduce the number of lines would generally be impracticable (given other constraints) or in fact reduce their readabilitiy.

I cannot tell the publisher to install further software. If I cannot get taller angle brackets from pdflatex, then I will need to fall back to using fewer distinct delimiters (which will make it harder for the reader to parse the formulae).
