Supported in partVerified against the work's full text
The patent shows a concrete loss-of-pressure mechanism that applies the brakes without operator action, one instance of passive signal-loss safing.
“the escape of the air therefrom brings the valve K into operation as before, and the brakes are applied without the intervention”
- The mechanism design ensuring the safe state is achieved passively (gravity, spring, mechanical detent, signal loss) not by active control
Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 1 of 3 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
