Title: Inert gas loss compensator for combustible liquid tank - has auxiliary emergency inert gas source with regulating valve
IPC: B63B25/10
Filed: 1974-06-11
Abstract: A vacuum valve opens automatically at a given pressure to admit air into the tank during discharge of the liquid contents. A pressure detector communicates with the interior of the tank to provide a signal when the pressure of the inert gas in the tank drops to a value just above the given pressure. A valve responds to the signal from the latter to assume inert gas from the emergency source. A pressure regulating valve is situated in the path of flow of gas from the emergency source and also communicates with the tank so as to control the pressure at which inert gas is delivered in response to the signal from the pressure detector. This pressure regulating valve automatically closes at a pressure slightly below the given pressure at which the vacuum valve opens while remaining open at a pressure above the latter pressure.

Title: Fibrous fleeces without surface faults for non-wovens - produced at high speed
IPC: D04H1/72
Filed: 1974-07-25
Abstract: An installation for the mfr. of fibrous fleeces has a long cylindrical separating wall with small perforations distributed uniformly over the whole of its surface except in a zone extending across the full width at the inlet for the untreated fibres. Inside the separating cylinder, a shaft rotating in bearings, carries the fibre distributor. This consists of a number of relatively thin plates, tapering from a broad centre section by which they are assembled on the shaft, to a fine point at each end and reaching close to the inner surface of the separating wall. The thin, narrow plates are arranged at different angles to each other without forming a spiral capable of diverting the air flow as it rotates and works with the separating wall to open out flocks into loose fibres. A housing of transparent plastic material encloses the separating cylinder, forming with it an annular chamber which opens out gradually downwards towards the fibre delivery opening, so that constant air speed is maintained in all zones. The sections forming the housing have slots between them extending across the full width and connecting to the outer air to admit a controlled quantity of air. Slots along the fibre inlet with dampers at each side control the ratio of air to fibre. Below the conveyor at the fibre delivery, is a suction box to deposit and stabilise the fibres on the belt. Produces single and multi-layer fleeces of uniformly distributed fibres without surface faults and at high speed for high quality non-wovens.

Title: Porous electrode for electrochemical cells - has porous conductive layer with a binder, esp. of PTFE and an ion exchange layer with the same binder
IPC: H01M12/02
Filed: 1976-07-07
Abstract: Porous electrode contains a porous electrically conductive layer contg. a binder, in contact with an ion exchange layer contg. the same binder as the conductive layer. The two layers may be in direct contact, or they may make contact via an intermediate layer which contains the same binder as the other two layers. Pref. the binder is a polymeric material, esp. PTFE, and the concn. of binder in the electrically conductive layer is 5-50 wt. %, esp. 8-30 wt. %, and in the ion exchange layer 5-50 wt. %, esp. 5-15 wt.%. The electrically conductive layer is pref. sufficiently porous to allow permeation of gases and liquids, but is sealed with a gas-permeable, liquid-tight layer of the same material as the binder in the electrically conductive and ion exchange layers. The electrodes are useful in electrochemical cells in which >=1 of the materials is gaseous, whereby one side of the electrode is in contact with the gas and the other side with a suitable electrolyte, so that the electrode reactions occur in the pores in the region of the gas/liq. contact interface. The ion exchange layer protects the electrode against penetration of harmful ions from the electrolyte into the electrochemically active material. In particular, the fuel cell may be run on air contg. CO2, which causes the formation of carbonate ion in the electrolyte, which has previously caused a deterioration in the electrochemical processes in the cell. The electrodes have high mechanical strength so that the chance of parting of the layers in use, is overcome. The electrodes can be made easily by standard methods, and can be made very thin so that the internal resistance of the electrode can be lower than when using unbonded ion exchange membranes.
