Patent DE-2732774-A1 (DE)
Title: High temp. gas cooled reactor with top reflector cooling - by secondary gas flow driven by own power source
Inventor: WACLAWICZEK HERBERT V ING GRAD
IPC: G21C15/18
Filed: 1977-07-20
Abstract: A gas-cooled, high temp. reactor has a cooled top reflector, a first or principal gas cooling circuit driven by a blower and providing a pref. downward flow of gas through the core, and a second gas cooling circuit. In this second cooling circuit gas passes through an intermediate space between the pressure vessel and the top reflector; the circulation in this second circuit is maintained by a second blower, driven by a heat engine, which obtains its heat from this second cooling circuit. The heat engine may be a gas turbine driven by the gas in the second cooling circuit, or it may be a steam turbine, supplied from a steam generator itself heated by the gas of the second cooling circuit. Used in particular for a high temp. reactor of the pebble-bed type with downward flowing helium. Under normal shutdown conditions downward helium flow at reduced rate is maintained by the primary circuit blowers; if, however, the blowers should fail, convection reverses the direction of flow to an upward flow through the core, consequently heating up the top reflector. The secondary circuit serves for cooling this reflector and its power source is the heat which it receives in this cooling operation. The power supply under these emergency conditions is thus completely independent of the first cooling circuit and also of outside power sources.

The mainspring will return the rod to its original position after impact.
Patent DE-2736461-A1 (DE)
Title: Nail driver actuated by gas explosion - has valves operated in sequence to supply correct mixture of air and gas
Inventor: LIESSE MAURICE
IPC: B27F7/09
Filed: 1977-08-12
Abstract: The nail driver has a main piston (29) which pushes a rod through the guide to drive the nails held in the magazine. When handgrip is depressed it pushes down a U-shaped member which opens the gas inlet valve and allows the gas to flow into a chamber inside the hollow piston rod (36). Further movement of the handgrip depresses a plunger which allows a spring to pull a lever downwards. The motion of this lever releases a series of interconnected levers and valves with the result that the gas flows into the combustion chamber followed by the correct amount of air. The mixture is then ignited and drives the piston (29) downwards against a spring.
