Title: Method of exhausting ethylene oxide gas after gasification of object intended for sterilization and apparatus for making the same
Inventor: DRZEVITZKY BERND
IPC: A61L2/20
Filed: 1995-05-30
Abstract: A process and device are disclosed for disposing of ethylene oxide gas used for sterilising objects within a vacuum sterilisation chamber (5) by means of a pump (10) connected to the sterilisation chamber (5) that supplies ethylene oxide after sterilisation to a gas scrubber (15) that works with acids. The sterilisation chamber (5), the pump (10) and the gas scrubber (15) form a closed gas circuit; the pump (10) continuously delivers ethylene oxide from the sterilisation chamber (5) to the gas scrubber (15), and the exhaust gas from the gas scrubber (15) is supplied to the sterilisation chamber (5). The ethylene glycol formed from ethylene oxide in the gas scrubber (15) is continuously withdrawn from the gas scrubber (15) and further acids are continuously added to the gas scrubber (15) depending on its acid consumption. This cycle is maintained until the residual concentration of ethylene oxide in the gas circuit falls below a predetermined level. An inert gas source (48) is preferably connected to the gas circuit (5, 35, 10, 39, 15, 40, 38) to supply inert gas to the gas circuit in a controlled manner when the ethylene oxide elimination causes the gas circuit inner pressure to fall, the pressure drop in the gas circuit being adjustable.

Title: Mechanism for aligning longitudinal axis of valve seat machining tool with valve axis guided to common axis by making use of a guide jib
Inventor: GERARD DANIEL
IPC: B23Q1/64
Filed: 1996-06-12
Abstract: Means for aligning the device include a ball holder (17) placed on a base (4) in such a way that it is movable in all directions in a horizontal plane during the positioning phase of the spindle (6), a spherical ball (13) freely rotatably mounted in the ball holder (17), and a substantially vertical quill (10) that is axially movable within the ball (13) and supports the tool driving spindle. Said spherical ball (13) has weights that balance the weight of the means for translating the quill (10) and that of said quill and said spindle when the latter are in the lower aligned position, so that said weights return the centre of gravity (G) of the assembly substantially into alignment with the axis (x, x') of the quill (10), whereas the electrical means (28, 29) for driving the spindle (6) are arranged in the quill (10) and thus locate the centre of gravity thereof on said axis (x', x) and close to the centre (C) of the spherical ball (13) when said quill is in the lower aligned position. Furthermore, means for generating a planar air cushion between the base (4) and the ball holder (17) include jets (47) arranged in the base (4) opposite the ball holder (17) for feeding a film having a uniform thickness, and clamping means include nozzles (62) separate from the cushion-forming jets (47) and capable of being connected to a vacuum source.

Patent ES-8706794-A3 (ES)
Title: Recovery of petrol from mixts. with air
IPC: B01D3/26
Filed: 1986-01-17
Abstract: A method of the type in which gasoline is recovered from a mixture of gasoline vapour and air by absorbing the gasoline in a cooled petroleum distillate is described in which a petroleum distillate having a boiling point range above that of gasoline is used and the petroleum distillate is then cooled by exchanging heat with a cold sink, placing the gasoline/air mixture in direct contact for absorption of the gasoline, transfer to an intermediate tank and transfer from the intermediate tank to a separation device which may comprise a distillation column. By combining condensation by cooling and absorption of the gasoline vapour and by controlling the quantity of cooled petroleum distillate placed in contact with the gasoline/air mixture so that the gasoline concentration in the petroleum distillate transferred to the intermediate tank is substantially constant it is possible to achieve optimum control, which has hitherto been impossible to achieve, of the process of absorbing the gasoline in operations performed under conditions of both maximum load and medium load. The system or installation for putting the method into practice is advantageous because only the absorption device 2 has to be dimensioned for operation under maximum load conditions, while the other components such as for example the distillation column 5 or heat exchanger 4 and their associated pipework can be dimensioned for operation under medium load conditions, an intermediate tank 3 being provided for the temporary receipt of petroleum distillate, which as a result of the control mentioned above 15, 16 has a substantially constant gasoline concentration with the result that the system or installation can satisfy maximum loads with a surprisingly small intermediate tank 3.
