Title: Swivel tilt fitment for wall-mounted mirrors - has two elongated sections also forming handle and providing stable support for mirror
Inventor: ROTH ECKART
IPC: A47G1/24
Filed: 1980-01-16
Abstract: The mirror is swivelled about a horizontal axis at its lower edge by a tilt fitment comprising two mirror symmetrical parts fixed separately on the wall at a spacing equalling the width of the mirror. Each part has a fixed elongated section member associated with the wall and a swivel elongated section member associated with the mirror. The two section members (7,8) are connected together at a distance from a connecting articulated bolt (9) by a retaining rod (10). This rod is connected locally fixed to one longitudinal section (8) by a swivel pin (11) but is displaceable on the other section member (7) in a longitudinal slot (13) by a further swivel pin (12). The end of the rod facing the longitudinal slit runs towards a stop e.g. formed by the slot end (14)when the longitudinal sections reach the angular positions corresponding to the inclined position of the mirror. The swivel longitudinal section member serves both to hold the mirror and as a handle to move the mirror without having to touch the latter.

Title: Solid bed pressurised gas generator with increased output - achieved by controlling size of coal briquettes, ash temp., and speed of ash removal
Inventor: SCHOLZ GUENTER DIPL ING DR ING
IPC: C10J3/34
Filed: 1980-12-08
Abstract: Generator is used for the gasification of brown or mineral coals which may vary widely in their coking properties. The amt. of coal which can be fed down the generator shaft is increased by using the size of the coal particles (e.g. briquettes) as a parameter for process control. The stability of the solid bed is maintained by keeping the velocity of the gas fed through the bed at a level below that causing fluidisation of the coal. Optimum conditions of gasification are pref. achieved by controlling the temp. of the ash obtd. from the coal, and also by varying the speed at which the ash is removed from the base of the generator. A computer is pref. used for process control. Automatic process control can be employed to increase the productivity of the generator.

Title: Stackable chair for seating in rows
Inventor: HENSEL WILLI
IPC: A47C3/04
Filed: 1981-03-16
Abstract: A stackable chair with armrests, whose armrest supports are arranged laterally on the legs of the chair frame. The armrest supports are mounted on the upper transition bend of the legs so that they can be pivoted outwards. Attached to the armrest support is a side bracket which is mounted on the pivot arranged in the connection piece. The pivot bearing of the armrest support is located outside the centre of gravity of the support. By means of a sloping end flattening, the armrest support remains in the sloping position when pivoted out. This exposes the stacking space. In its vertical position of use, the armrest support engages in a ratchet. The ratchet is automatically operated by the dead weight of the chair when the chairs are stacked. This also takes place when the stacked chair is lifted out.

Title: Process for the continuous generation of fuel gas, and shaft furnace for carrying out the process
Inventor: MALLEK HEINZ
IPC: C10J3/26
Filed: 1981-04-01
Abstract: For the continuous generation of fuel gas from organic material, in particular from organic wastes, the wastes are filled into a shaft furnace through which they migrate by gravity as a dumped layer. In the shaft furnace, the wastes are dried, degassed and gasified with addition of a gasifying agent, an incandescent bed being formed. In order to be able to crack tarry and oily constituents, formed during the gasification, to give volatile compounds, the gasifying agent is introduced above the incandescent bed as a function of the temperature of the latter and passed, together with gases being evolved in the dumped layer, in the direction of flow of the material over the dumped bed through a discharge slot provided for the discharge of the material from the incandescent bed. In this process, the throughput of the material through the discharge slot is controlled in such a way that the material remains above the slot until it has been gasified.
