Abstract
Abstract The invention relates to a self-contained apparatus used for constant pressure sampling of gaseous beverages especially during fermentation. The apparatus is provided with a tripod (3) and grip frame (15) with a stand for the sampling container (20) and for an inert gas bottle. In the upper part, a distribution-head has two inlet-taps (23 and 24), a pressure-tap (35), and a closing member with an injection cannula (21). Moreover, the apparatus comprises between the distribution-head (16) and the pressure-tap (35) an element (38) for adjusting the flow of the evacuating system, being operated by the pressure-tap.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
157 words
A self-contained constant pressure apparatus for sampling gaseous beverages, comprising a frame composed of a tripod and a central inclined stand surmounted by an upper block provided with a handle, with the central stand comprising a first support for a sample drawing recipient (20) and another support for an inert gas bottle (7), and the upper block comprising a distributor-head (16) including two taps (23,24) for admission and regulation of gas and liquid, an exit leading into a tap (35) for pressurising said exit, a regulation valve (38) acting upon distributor-head evacuation means and monitored by the tap (35); the distributor-head at its lower face having an stopper (19) with joint (18) for receiving a neck of the sample drawing recipient; the distributor-head including a common inner chamber (25) for said evacuation means including an evacuation circuit (40), said apparatus including tightening means (43) for applying said neck of the sample drawing recipient against the stopper (19).
Claim 2
Dependent Claim
157 words
A self-contained constant pressure apparatus for sampling gaseous beverages, comprising a frame composed of a tripod and a central inclined stand surmounted by an upper block provided with a handle, with the central stand comprising a first support for a sample drawing recipient (20) and another support for an inert gas bottle (7), and the upper block comprising a distributor-head (16) including two taps (23,24) for admission and regulation of gas and liquid, an exit leading into a tap (35) for pressurising said exit, a regulation valve (38) acting upon distributor-head evacuation means and monitored by the tap (35); the distributor-head at its lower face having an stopper (19) with joint (18) for receiving a neck of the sample drawing recipient; the distributor-head including a common inner chamber (25) for said evacuation means including an evacuation circuit (40), said apparatus including tightening means (43) for applying said neck of the sample drawing recipient against the stopper (19).
Claim 3
Dependent Claim
37 words
Apparatus according to claim 1 characterized by the fact that the stopper (19) is perforated at its center by an injection cannula (21) connected to said taps (23, 24) and has a second passage (22) for evacuation.
Claim 4
Dependent Claim
46 words
Apparatus according to claim 2 characterized by the fact that the evacuation circuit (40) begins at said second passage (22), goes through the distribution-head (16) by an interior circuit and the common inner chamber (25) and afterwards through the regulating valve (38) to an effluent collector.
Claim 5
Dependent Claim
29 words
Apparatus according to claim 1 characterizied by the fact that the tap (35) is connected to a drain (36) with a micrometric screw allowing for communication with the atmosphere.
Claim 6
Dependent Claim
34 words
Apparatus according to claim 1 characterized by the fact that the tightening means (43) are adjustable and terminated by a bent extremity (45), pushable into contact with a bottom of the sample drawing recipient.
Claim 7
Dependent Claim
32 words
Apparatus according to claim 1 or 4 characterized by the fact that the tap (35) is connected to the valve (38) by a pipe (37) transmitting operating pressure to the valve (38).
Claim 8
Dependent Claim
50 words
Apparatus according to claim 1 characterized by the fact that the valve (38) is a membrane type valve having two outlets connected in said evacuation means and acting according to membrane pressure on said two outlets in order to regulate the flow and the pressure in the evacuation circuit (40).
Claim 9
Dependent Claim
28 words
Apparatus according to claim 2 characterized by the fact that the length of the injection cannula (21) is about three quarters of the length of the measurement recipient.
Claim 10
Dependent Claim
24 words
Apparatus according to claim 1 characterized by the fact that the common inner chamber (25) leads via a measuring pipe to a pressure unit.
Claim 11
Dependent Claim
51 words
Apparatus according to claim 1 characterized by the fact that said other support (6) includes two parallel rings (8) and (9) forming a collar, with one of said rings (8) being lower than the other ring (9) and having a cross bar (10) for supporting a bottom of the gas bottle.
Claim 12
Dependent Claim
26 words
Apparatus according to claim 1 characterized by the fact that the sample drawing recipient is protected by a transparent convex cover (12) on said first support.
