Such single words with different meanings in different contexts are probably best described as industry-specific jargon than improper nouns. Even so, I'm still greatly upset when people take word and give it a more specific meaning in a technical context. For example, the term "container" such as in Docker container or LXC container. Container is such a generic term, but has a much more specific meaning in computing. I wish someone had invented a new term for it. As a good example, I take "blog" which was basically a new term for a new thing. I know that it has it's origins from the term "web log", but now everyone just says "blog". It's nice to have a new a term instead of taking old words and putting them into a new context.
