Title: Open fireplace insert
Inventor: GUT MAX
IPC: F24B1/183
Filed: 1979-09-04
Abstract: The open fireplace insert is arranged in the grate of an open fireplace and is used to exploit the heat of the fire and the smoke gases. Hollow fire guiding combs (4) are arranged on an upper section (3), which is inclined forwards, of the insert. The said combs have lateral heat exchange surfaces, which form flow channels for the fire and the smoke gases. The smoke gases are only slightly deflected by the flow channels before they ascend into the chimney. They pass over the entire surface of the fire guiding combs, resulting in a high level of efficiency of heat exchange. <IMAGE>

Title: Gas-sealed shaft sealing for a fermenter
Inventor: PLOECHINGER HERBERT
IPC: C12M1/02
Filed: 1976-07-08
Abstract: The shaft sealing has a housing with a part (4) attached to the fermenter vessel (1) and a rotatable part (5) which is firmly connected to the stirrer shaft (3) by means of screws (14) and is sealed off fluid tightly with respect to the shaft (3) by O-rings (7, 7'). Recessed into the fixed part (4) is an annular chamber (10) which accommodates a lip seal (6) which seals off the annular chamber with respect to the shaft (3). Provided between the two housing parts (4, 5) is an annular gap (11) through which there flows the sealing gas, which is passed into the annular chamber (10) via connecting stubs (9'). On the circumference of the rotatable part (5) there is a closing element (12) which prevents backflow from the fermenter vessel (1) through the annular gap (11).

Patent FR-2033146-A5 (FR)
IPC: H01M4/90
Filed: 1970-02-27
Granted: 1970-11-27
Abstract: A method for the preparation of an electrocatalyst which comprises (a) electrodepositing less than a complete monomolecular layer of material on a substrate utilizing cathodic polarization of short duration, and (b) oxidizing the electrodeposit and the substrate utilizing anodic polarization, also of short duration is described. The deposited material preferably is a metal or metal oxide having useful catalytic and/or electrical properties, e.g., platinum or gold. The substrate preferably is a metal or metal oxide such as tantalum oxide, tungsten oxide, or a sodium tungsten bronze, NaxWO3. The substrate is treated in an electrolyte containing a very dilute solution of the material to be deposited and/or in the presence of a counterelectrode containing this material. Several repetitions of these method steps, i.e., reversing the polarity such that the deposition and oxidation steps alternate, results in the complete or partial integration of minute portions of electrodeposited material in the substrate material. This method is useful for providing or improving catalytic activity in a substrate. The products produced by the method are useful in electrochemical devices.
