Title: Process for storing and producing power by storage of alkali metals produced electrolytically
IPC: H02J1/14
Filed: 1980-05-29
Abstract: A process for recovering power is disclosed, by which excess electric power is exploited for electrolyzing alkali metal hydroxides (molten) and the thusly obtained pure alkali metals are stored.

Title: Heat exchanger
IPC: F23L15/04
Filed: 1981-03-31
Abstract: A combustion air preheater for heating combustion air with heat energy provided from flue gas includes both a heat pipe type heat exchanger for effecting low temperature heat transfer between the flue gas and the combustion air and a tube-and-shell type heat exchanger for effecting higher temperature heat transfer. The preheater includes a first heat exchanger, having first and second heat transfer compartments with a plurality of heat pipes extending therebetween and a second, connected heat exchanger which includes a plurality of heat tubes supported by tube sheets within a shell. Ducting is provided to direct flue gas over the tubes of the second heat exchanger and then through one of the compartments of the first heat exchanger and additional ducting is provided to direct combustion air through the other compartment of the first heat exchanger and through the tubes of the second heat exchanger. Heat energy is transferred through the walls of the tubes in the second heat exchanger to the combustion air in a first, higher temperature range with additional heat energy transferred to the combustion air in the first heat exchanger in a second, lower temperature range through the heat pipes. The preheater advantageously uses the heat pipes in the lower temperature range and the tube-and-shell heat exchanger in the higher temperature range to effect high overall preheater thermal efficiency over a wide temperature range with minimal corrosive attack on the heat exchange surfaces.

Title: Signalling device.
IPC: F41C3/02
Filed: 1983-12-14
Abstract: A signaling device for firing signaling cartridges in an emergency. The signaling cartridges are adapted to emit light, noise and or smoke signals. The device includes a grip which is manually grasped and which includes a firing lever adapted to be pressed inwardly. The firing lever when in a normal inoperative position forms part of the grip contour. When the firing lever is pressed inwardly it lifts off a rotatably mounted hammer from a firing pin. The hammer then snaps back via the force exerted by a spring to actuate the firing pin. Simultaneously with actuation of the hammer the firing lever also effects a rotational advance of a cartridge magazine of the signaling device. Alternately, the cartridge magazine can be rotationally advanced with the thumb of the user of the device. When the signaling device is held in its "natural" position it is vertically upwardly oriented so that signaling cartridges are fired in that direction.
