5.WO/1988/001228EXPANDABLE RING TO SEAL A CASING TO THE BEAD OF A TYRE TO BE RETREADED

WO - 25.02.1988

Класс МПК B29D 30/54 № заявки PCT/EP1987/000459 Заявитель VV-SYSTEM AG Изобретатель SCHIMANEK, Karl

Expandable ring (1, 100, 50) to seal a casing (42) to the bead (43) of a tyre to be retreaded, during pressure and heat treatment in an autoclave. The expandibility of the ring is obtained by means of notches (22) or by a fork (33) or tongue (32) configuration at each end (4, 5) on both sides of the opened region (2). In each case a partial separation gap (23) is obtained extending in the peripheral direction. Depending on the shape of the bid, the sealing surface (20, 30) is provided with a cylindrical or truncated cone configuration, whereby lateral stops (21) or edges (31) facilitate positionning. Expansion is caused by the inherent tension of the ring (1), either manually or by means of tension jacks (54).

6.WO/1985/002455SOLID FUEL HEATING APPLIANCES

WO - 06.06.1985

Класс МПК F24B 1/00 № заявки PCT/US1984/001929 Заявитель VERMONT CASTINGS, INC. Изобретатель FERGUSON, Robert, W.

The heating appliance includes an insulated secondary combustion chamber (22, 110) where a mixture of exhaust gases from the primary combustion chamber (12, 112) and secondary air is burned. A catalytic igniter (34, 130) is provided in the secondary combustion chamber. In a retrofit embodiment (115) for existing stoves, a sheet metal partition (122) in the secondary combustion chamber allows heat transfer from spent gases to the entering mixture of exhaust and secondary air. In a unitary stove embodiment (10), secondary air is heated by the spent gases which proceed to remote heat exchangers (48) separated from the primary firebox by ventilated air spaces (50). The combination of the insulated secondary combustion chamber, catalytic igniter, and the regenerative heat transfer assure substantially continuous combustion within the secondary combustion chamber even when conditions in the primary combustion chamber change. To prevent room emissions, the stove door is sealed by a vented double gasket system (62, 64).
