Title: Soft energy turbine generator - converts excess mechanical energy not required for electricity generation into heat using hydraulic pump circuit
IPC: F03B13/00
Filed: 1980-07-15
Abstract: The energy recuperation system has a rotary turbine driven by wave motion or wind, or an expansion motor associated with a solar collector. The rotational energy is connected into electrical or heat energy via a hydraulic pump directly or indirectly. Pref. the operation of the hydraulic pump causes oil to be extracted from a reservoir and fed around a circuit containing two hydraulic motors, each coupled to an electrical alternator. The motors are pref. coupled in parallel arms of the circuit either of which can be selectively blocked, one used in summer and the other in winter. The oil is returned to the reservoir via a choke so that it is heated, with a heat exchanger recovering the calorific energy for supplying hot water etc.

Title: Chemiluminescent dose measuring appts. for atmospheric gas components - contains sync. detection system for measuring outputs of photomultipliers sensing luminescence in reaction chambers
Inventor: CHARPENET LOUIS
IPC: G01N21/76
Filed: 1980-12-04
Abstract: The sealed enclosure houses two reaction chambers with parabolic cavities into which injection nozzles feed the atmosphere for analysis and the reactive gas. A blanking disc common to both chambers is driven by a motor and has slots which mark and unmark windows in front of photomultiplier tubes. Photodetectors provide signals to ensure synchronous operation. The tube outputs are dependent on the chemico-luminescence generated by the reaction of the air from a pump and pressure regulator and the oxygen from a glow discharge tube activated by EHT from a generator. The photomultiplier outputs are applied to synchronous detectors and amplifiers to provide the respective output signals indicating gas content.

Title: Safety belt system
Inventor: HERSON S
IPC: B60R22/02
Filed: 1981-09-04
Abstract: Safety shoulder-belt (for front and back seats) which embraces any adult or child body. The belt is formed of a single strap folded in three strands: 1 dorsal-2 toracic-3 abdominal comprising the reserve. This reserve is either static and folded, or absorbed with said abdominal strand in a winder. There is no vertical strand; the thoracic strand is fixed on the suspension buckle above the door. A rectangular buckle is fixed on the dorsal strand at the shoulder level and is connected to the thoracic strand. Independently from the three anchoring points, there are four attaching points by keyed rosettes: 1 on the suspension buckle, 2 on the shoulder, 3 on the locking buckle, 4 on the abdominal strand. In case of accident, all the attaching points are of the instanteneous unfastening type, even if the body leans of all its weight on the strands. A covering for the dorsal and thoracic strands, padded with a foam band on the inner face covering the thoracic strand and the shoulder dampens the shocks. In case of capsizing of the vehicle, there is no risk of either strangling or ejection, or of the body knocking against the top.
