Title: Process for thermal pyrolysis of hydrocarbons using a gas generator and using an external combustion of a fuel with compressed air
Inventor: ARI MINKKINEN
IPC: C10G9/20
Filed: 1991-11-08
Abstract: Improvement to a process and to a device for carrying out endothermic chemical reactions such as a steam-cracking reaction for producing ethylene. The heating gases under pressure travelling in the calandria (14) of a heat exchanger-reactor (11) are conveyed into at least one power-recovery turbine (22) which puts into action at least one air compressor (51) into which an appropriate volume of air is conveyed. The air is compressed to a determined pressure and heated in a combustion zone (55) distinct from that (1) feeding the heat exchanger-reactor. The compressed heating effluents are also conveyed into the calandria of the heat exchanger-reactor (1). The energy recovered in the power-recovery turbine thus makes it possible to reduce the number of gas generators (1) supplying heating gas to the heat exchangers-reactors.

Patent FR-2693449-A1 (FR)
Inventor: JEAN-MARIE BAUMARD ERIC
IPC: B67B7/04
Filed: 1992-07-07
Abstract: An apparatus driven by a battery-powered (17) electric motor (11). The motor (11) may be actuated simply by inserting a bottle neck into an abutment portion (1). The motor drives a corkscrew member (8) via a reduction gear (10) so that it penetrates the seal and cork, and lowers the assembly (10, 11) along two fixed guides (7). A portion (9) engages a sleeve (5) which the rotational force pivots through ten degrees to enable a circular blade (3) secured to the sleeve (5) to cut through the seal. After the cork has been fully drawn up, the motor (11) switches off, and when the bottle neck is withdrawn, the direction of rotation is reversed until the cork and seal are ejected, whereafter the motor (11) cuts out. At no time during the whole operation does the user need to handle the apparatus or the bottle.
