Title: Wall insert for panel heating of rooms - has capillary inserts to control flow of heat across insert
Inventor: LAING NIKOLAUS
IPC: F24S10/95
Filed: 1973-06-16
Abstract: The insert absorbs solar energy during the day and releases it to heat the room at night. It has an external panel (3) which is flush with the external wall and is of a material which will absorb solar radiation but will not emit radiation itself. An internal panel (5) is flush with the inside wall. The space between the panels is filled with a medium which evaporates when heat is being absorbed during the day and condenses as it gives up heat at night. The internal face plate (5) has channels (6) which collect the condensate and there are pieces of absorbent capillary material (32) dipping into these channels. The depth to which they dip can be adjusted and varies the rate of heat transfer.

Title: Inertially operated ski brake - has magnet and iron core attached to cable to separate ski and shoe
Inventor: PINTER ADOLF
IPC: A63C9/00
Filed: 1974-03-06
Abstract: The ski safety arrangement comprises a strap consisting of two parts connecting the shoe with a brake and also to the ski. When through a fall a force acts on the straps, a first pressure taken by a spring pulls a pin from a braking device mounted on a shaft, which can then turn through 180 deg. The resulting force then separates a magnet from a soft iron core and so parts the straps. A housing mounted on the magnet and core prevents these from separating by sliding sideways.

Title: Electrolytic cell with rotating electrodes - having hollow shaft to which electrodes are attached through which electrolyte passes
Inventor: FRANCKE DIETHARD DIPL ING
IPC: C25B9/12
Filed: 1974-06-18
Abstract: Electrochemical cell has impervious electrode plates mounted in a symmetrical circular fashion forming a closely packed bundle of plates close to or on top of one another. These are spaced by spacers which form an electrolyte space between them, the spacing being 10 mm. The plates are arranged around a hollow rotatable shaft, the hollow space being connected to the electrolyte space and, being attached rigidly to the shaft, rotate with it when it rotates. The bundle can rotate as a whole, or all but the outer now of plates can rotate. Alternatively the plates can alternately rotate and stop. The electrical efficiency is much improved by close packing of the plates. However it can lead to high local current densities with consequent local corrosion of the plates. The centrifugal bundle gives the advantage of close packing but avoids the local corrosion.
