    Abstract: A dispersion of a polyurea in an aromatic polyisocyanate is prepared by mixing the polyisocyanate with one or more aliphatic diprimary diamines having (a) at least one amine group attached to a carbon atom having not more than one hydrogen atom attached thereto or (b) at least one amine group attached to a carbon atom which is itself attached to a carbon atom having not more than one hydrogen atom attached thereto, provided that both amine groups are not attached directly to separate rings of an alkylene-linked polycyclic aliphatic ring system. The reaction preferably takes place at a temperature in the range 20.degree. C. to 60.degree. C. The polyurea dispersion products are useful for manufacture of polyurethane foams and elastomers of superior physical properties.

    Abstract translation: 聚脲在芳族多异氰酸酯中的分散体是通过将多异氰酸酯与一种或多种脂族二原子二胺混合来制备的，所述脂族二原子二胺具有（a）至少一个连接于不超过一个氢原子的碳原子上的胺基，或（b） 连接到碳原子上的至少一个胺基团，其本身连接到与其连接的氢原子不超过一个的原子的碳原子上，条件是两个胺基团不直接连接到亚烷基连接的多环脂族环系统的分开的环上。 反应优选在20℃至60℃的温度下进行。聚脲分散体产物可用于制造具有优异物理性能的聚氨酯泡沫和弹性体。

    Abstract: A cassette for a draw-out circuit breaker apparatus is disclosed. The cassette comprises a base having a front edge and a back edge, the back edge defining a back plane, a set of shutters disposed at the back plane and configured to open and close, and a set of shutter locks extending from the front edge to the back edge and in operable communication with the set of shutters. The shutter locks are biased toward a first position. In response to the shutter locks being driven toward a second position, the shutters are restrained from opening. The shutter locks are configured to be restrained in the second position.
