Title: Plastics hose helically wound with reinforcement from spools - mounted coaxially around hose blank on revolving hollow shaft
Inventor: HECKER ROLF
IPC: B29C53/60
Filed: 1974-09-05
Abstract: An appts. for wrapping the blank of a rubber or plastics tube, to make a reinforced hose, applies a number of layers of helically wound reinforcing filaments. The tube blank is pulled longitudinally through the centre of a number of freely revolving spools, each of which feeds one filament onto the tube blank. Pref. all these spools are mounted on a hollow shaft surrounding the tube blank and driven at controlled speed. The spools are held between end stops of which one is pref. constructed as a flange with one guide opening near its periphery for each of the filaments, more specifically also with a guide number having additional guide apertures much nearer to the axis of the tube. These latter openings may be oblique to the axis, and the whole guide element angularly adjustable and interchangeable on the flange. Each spool may have a brake applied to it to tension the reinforcing filaments. The whole appts. can be rotated at relatively high speed, since there are no out of balance forces. In addn., since each spool entirely surrounds the tube, the storage capacity of a spool is considerable, enabling a long length of tube to be wound.

Title: Rechargeable sodium-sulphur cell - with sodium-saturated metallic felt filling anode space inside ceramic electrolyte
Inventor: BAUKAL WERNER DIPL CHEM DR
IPC: H01M10/39
Filed: 1974-11-27
Abstract: A rechargeable galvanic sodium/sulphur cell uses a solid ceramic electrolyte which is a conductor for sodium ions for separating the anode space from the cathode space. The anode space is filled with a fine-pore metallic felt which is saturated with sodium. Porosity and pore size are so designed that the internal resistance of the cell rises steeply when the anode space has been depleted or the cell discharged to the max. permissible value. This provides a simple signal to indicate that the discharge has reached its limit. Its prevents serious damage to the cell, specially to the ceramic electrolyte. In case of a breakage, the sodium is retained by the felt.
