DEFINITION

Classification: 141/37

(under the class definition) Apparatus comprising filling systems dealing with a plurality of contents materials, at least one of which is a gas, and which deal with the receiver gas content under conditions which must necessarily be other than atmospheric.

(1) Note. The provision of plural diverse paths for gaseous fluid between the receiver and either or both the supply or the atmosphere is considered without more to characterize a system of this type. The diverse paths may be either branched or noncommunicating.

(2) Note. The filling of an inverted receiver is included when the liquid content is displaced by gas and no confined flow path for the liquid is provided.

(3) Note. Included are:

(a)

gas pumps, including siphon starting pumps for receiver air, liquid displacement by gas and evacuation means claimed broadly where liquid flow will not otherwise occur.

(b) gas storage, comprising either a supply separate from the other material supply, which gas supply is either connected directly to the receiver or is connected to a supply which is vented to the receiver, or storage of gas displaced from the receiver, including temporary confinement of such gas in a material-handling trap.

(c)

plural or variable cycles in handling receiver gas content.

(d)

plural diverse gas passages.

(e)

use of the gaseous contents material as servo fluid or seal.

(f)

automatic control of liquid flow by gas condition in receiver, but not including mere equilibrium states where a vent is closed.

(g)

sequential operation of diverse valves only in apparatus having filling during lateral travel of registering head and receiver. SEE OR SEARCH THIS CLASS, SUBCLASS:

4+, for processes relating to the filling of receivers under conditions or with steps which involve provision of a nonatmospheric or variations in the gaseous state in the receiver.

70, for material treatment with fluid contact, i.e., those devices where gas is introduced into an open container which is already filled, or in connection with the filling thereof.

91+, for treatment by fluid of the receiver or of the filling or dispensing apparatus, especially subclass 92 for gaseous pretreatment of the receiver, connection between which and the nongaseous supply apparatus is broken between the cleaning operation and the filling operation.

93, for suction hoods and off-takes for soil removal or preventing.

115+, for drip prevention or over-fill removal by evacuation or suction, especially subclass 127 for over fill removal in gas filled receivers.

285+, for multiple passage filling means or filling heads for diverse material or flows, and see the search notes to subclass 285.

323, for residual siphon type filling apparatus, and see the search notes thereto.
