Patent DE-2222218-A1 (DE)
Title: Compressor shaft seal - with carbon ring sec seal shielded from corrosive fluid
Inventor: POTTHARST JUN JOHN E
IPC: F04D29/12
Filed: 1972-05-05
Abstract: A compressor for a corrosive fluid, e.g. salt water steam, has a shaft seal to prevent compressed fluid escaping along the shaft from the compressor casing; this seal comprises a first ring, sealed to and rotating with the compressor shaft, a radial surface of this seal running in sliding contact with a non-rotating but axially slidable carbon ring mounted in a housing fixed in a wall of the compressor casing, the carbon ring is urged by a spring axially against the first, rotating ring. Radially inwards of the carbon ring, the inner wall of the generally U-shaped housing for the fixed components of the seal surrounds the shaft as an annular strip but with a small gap between itself and the shaft through which corrosive fluid can flow; the annular gap between the inner wall of the carbon ring and the outer wall of the annular strip is sealed by a ring, pref. an O-ring of material having a coefficient of friction similar to PTFE; a sleeve fitting closely around the inner annular strip wall of the U-shaped housing and in bearing contact with the end wall of the housing prevents axial movement of this O-ring under the pressure of the corrosive fluid; thus, as the end surface of the carbon ring wears by contact with the first rotating ring, and the carbon ring thus slides axially under the spring force in compensation, those portions of the inner surface of the carbon ring which now come into contact with the O-ring have not previously been subjected to contact with the corrosive fluid. The arrangement ensures that those parts of the carbon ring not yet in contact with the O-ring are shielded from corrosive fluid.

Title: Thermo-electric energy source - heated by radioactive material
Inventor: BERGER WILFRIED DR
IPC: G21H1/10
Filed: 1972-06-07
Abstract: The source of thermal energy heats a plurality of thermocouples points, whilst other joints are at a lower temp., the bundle of thermocouples being surrounded by a cylinder having a reflecting inner surface to reduce energy loss by radiation, as in the Parent Patent. The inner surface of the reflecting cylinder is not flat, but has such as profile (e.g. ribs or saw-teeth) that the thermal radiation is reflected back towards the hot joints of the thermocouples, thus increasing the temp. gradient.

Title: Ceramic compsn. esp. for wall tiles - contg. anorthosite to compensate for shrinkage of other components esp. slag
IPC: C04B33/24
Filed: 1974-08-10
Abstract: Compsn. for the prodn. of ceramic articles such as wall tiles is based on anorthosite, which may be converted by metamorphosis or metasomathosis to the jaussuritised type Anorthosite is present in an amt. of 5-95 wt. % (pref. 20-50 wt. %) in the raw state or after firing. The first firing at 1000 degrees C should result in a lasting elongation >1%. The compans. may also contain blast furnace slag (opt. ground and expanded, or otherwise processed) forming a glassy phase surrounding anorthosite crystals. Anorthosite expands as firing so that the shrinkage of the other components of the ceramic material (esp. the slag) can be compensated for and articles free of lasting dimensional changes can be produced. The product has high mechanical strength, reversible thermal dilation, good shape stability, porosity properties and low extension in contact with moisture; cracks or microfissures are absent.

Title: Vehicle dual brake circuit control valve - has conical thrust surfaces for constant activation force with cooperating ball race
Inventor: VOLLMER OTTO
IPC: B60T15/04
Filed: 1975-02-22
Abstract: The dual circuit brakes are operated by two control valves which are linked by a special relay piston. The first valve is operated by the brake control and the second valve by the first circuit brake pressure via the relay valve. The coupling between the relay piston and the second valve is by special conical surfaces and a movable thrust element between them. The thrust element moves to compensate for pressure differences between the circuits and ensures an even activation force for the second valve, even when the brake controls are directly linked to the second valve in the event of brake failure in the first circuit.
