Title: Automobile door lock with double-arm lever bolt - has contoured ratchet engaging both bolt legs at closure
Inventor: CERDAN JACQUES
IPC: E05B85/26
Filed: 1978-11-04
Abstract: The door-lock is for use for automobiles and incorporates a pivoting forked bolt (7) which acts with a pivoting cammed ratchet plate (15) to engage a staple pin (4) on edge of the door.

Title: Gravity sedimentation method for determining particle size - measures progress of particles in fluid optically, by system with optical fibre and lens mounted on platform
Inventor: OTTO HEINZ JOACHIM ING GRAD
IPC: G01N15/04
Filed: 1979-02-23

Title: Personal pulse rate monitor for hazardous occupation - gives alarm if rate is outside preset limits unless wearer cancels warning
Inventor: TRATTNER HERMANN
IPC: A61B5/11
Filed: 1979-06-01
Abstract: A person, alone in a hazardous situation carries a monitor which warns him if his pulse rate rises or falls beyond pre-set limits. If he fails to cancel the warning within 10 seconds, the monitor sends an emergency call to a central control over a wire-less link. A signal, derived from the pulse of the person is compared with a variable signal, generated by the monitor. The variable signal may be pre-set to suit the conditions and/or controlled by a movement detector. The warning may thus be initiated by missing or too slow pulse when stationary, or too fast pulse when moving.
