Abstract
Abstract Apparatus, particularly for filling bottles with liquid, is provided with a device both for withdrawing gas from above the liquid entering the bottle and for simultaneously supplying gas to the space above the liquid. Therefore, when the liquid rises to a suction probe through which the gas is withdrawn, and so stops the withdrawal of gas, an immediate gas pressure rise occurs in the said space. This pressure rise is sensed and the filling operation consequently terminated.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
203 words
Apparatus for controlling the filling of a container which is closed except for an opening at the top thereof, including a unit for closing the container except for passages through said unit, a filling passage means through said unit for the passage of flowable material with which the container is filled, distinguished by the feature that there are two further passages through said unit consisting of a suction probe having its end substantially at the level to which the container is to be filled, and a pressure passage means through which gas is delivered under pressure while the container is being filled, the outlet of said pressure passage means being above said end of said suction probe, means being provided for withdrawing gas through said suction probe until the level of the material entering said container rises to a level at which it seals said probe, means being also provided for delivering gas under pressure through said pressure passage means while said container is being filled, further means being provided for sensing a rise in gas pressure above the material when the material seals said suction probe, and means responsive to said sensing means being provided for terminating the filling of the container.
Claim 2
Dependent Claim
203 words
Apparatus for controlling the filling of a container which is closed except for an opening at the top thereof, including a unit for closing the container except for passages through said unit, a filling passage means through said unit for the passage of flowable material with which the container is filled, distinguished by the feature that there are two further passages through said unit consisting of a suction probe having its end substantially at the level to which the container is to be filled, and a pressure passage means through which gas is delivered under pressure while the container is being filled, the outlet of said pressure passage means being above said end of said suction probe, means being provided for withdrawing gas through said suction probe until the level of the material entering said container rises to a level at which it seals said probe, means being also provided for delivering gas under pressure through said pressure passage means while said container is being filled, further means being provided for sensing a rise in gas pressure above the material when the material seals said suction probe, and means responsive to said sensing means being provided for terminating the filling of the container.
Claim 3
Dependent Claim
27 words
Apparatus according to claim 1, distinguished by the feature that said sensing means are connected to said pressure passage means to sense a rise in pressure therein.
Claim 4
Dependent Claim
41 words
Apparatus according to claim 2, distinguished by the feature that said sensing means comprise a fluidic relay device sensitive to a rise in pressure in said pressure passage means and operative on said means for terminating the filling of the container.
Claim 5
Dependent Claim
49 words
Apparatus according to claim 3, distinguished by the feature that a manually operable member for creating a fluid pulse is operatively connected to said fluidic relay, so that a manually created pulse can be transmitted to said relay for terminating the filling operation in the event of an emergency.
Claim 6
Dependent Claim
107 words
Apparatus according to claim 1 distinguished by the feature that reciprocating means under control of said sensing means are provided for applying said closure unit together with said filling passage means, said suction probe and said pressure passage means to said container and for withdrawing same from said container, and that a valve is arranged automatically to control the feeding of the material through said filling passage means in accordance with the positioning of said closure unit, said means for withdrawing gas through said suction probe and for applying gas pressure through said pressure passage means being arranged to function continuously during the functioning of the apparatus.
Claim 7
Dependent Claim
45 words
Apparatus according to claim 1 distinguished by the feature that said end of said suction probe is disposed adjacent and at least as low as the outlet of said filling passage means so as to enable said suction probe to remove drips from said outlet.
