Title: Emergency reactor shut down and test system - for water-cooled nuclear reactors
Inventor: ODE BENGT
IPC: G21C7/16
Filed: 1971-06-14
Abstract: Each individual control rod actuator in the water cooled nuclear reactor includes an emergency shut down hydraulic ram for whose propulsion a volume of water is contained in a hollow jacket around the actuator and which is pressurized from a high pressure source under control of an emergency shut down control valve in the pressure manifold to a distributor system. A test valve is placed on the high pressure side of the control valve and when the test valve is closed, a small volume only of gas at working pressure is introduced into the system and in conjunction with pressure gauges at the valves, the system is tested for water leaks i.e. the safety of the system is checked without full shut down and loss of output.

Title: Exhaust gas purification - using a hydrogen generator connected to the inlet manifold of an IC engine
Inventor: BOGAN SIMEON J
IPC: F02M25/00
Filed: 1972-03-30
Abstract: Exhaust gas purifier, for i.c. engines, comprises a steam generator connected to the inlet of a hydrogen generator having an outlet connected to the engine inlet, containing an assembly of iron spheres and maintained in heat exchange relationship with the exhaust system, to heat the spheres and produce hydrogen from the passage of steam over these. More especially, electrical heating is provided for heating the iron spheres in the hydrogen generator and also in the steam generator for vaporising the water. The introduction of hydrogen into the fuel/air mixture ensures that a higher combustion temperature is produced giving more complete combustion and therefore a reduction of unburnt hydrocarbons in the exhaust discharged to atmosphere.

Title: Water level control - in boiling water reactors of atomic reactors
Inventor: STERNER TORD DIPL ING
IPC: G21D3/00
Filed: 1972-11-13
Abstract: Electronic or pneumatic control system, for regulation of the water level in a boiling water reactor supplying steam in parallel to two turbines each with separate condensers and feed water pumps, responds directly to steam demands from each turbine and enables each set to act independently of the other. Coarse control of the water level is effected by varying the speed of the feed water pumps and fine control by activation of the isolating or regulating valves. The regulating valves in the feed water return operate within a 10-80% range open and the isolating valves 10% above or below the water level high and low limits.

Title: Drip-free grilling grid - uses inclined bars to conduct fat droplets away by adhesion and gravity
Inventor: HAUBNER GEORG
IPC: A47J37/06
Filed: 1974-01-18

Title: Guidance and suspension system for passenger vehicles - cools wheels bearings by rotating wheel supports transverse to curved track
Inventor: HELM AXEL-GUENTHER DR
IPC: F16C29/04
Filed: 1974-03-06
Abstract: The vehicle is supported on a number of X shaped brackets with four wheels one in each arm of the X. At any given time only one wheel of each bracket supports the vehicle on the rails which are equally spaced around the tunnel wall. The rails have oblique longitudinal grooves which co-operate with skew grooves in the wheels so that the brackets rotate as the vehicle moves forward. Thus each wheel goes through a continuous cycle of one quarter of the time under load and three quarters of the time under no load when the bearing can be cooled.
