DEFINITION

Classification: 141/192

(under the class definition) Apparatus having some element of control which operates in response to a condition in or about the receiver either to divert the material of the system elsewhere or to terminate its flow to the said receiver.

(1) Note. Where the bringing together of parts of the system establishes a flow path and subsequent flow of materials the system is not deemed automatic.

(2) Note. Establishing or maintaining a state of equilibrium (i.e. without flow cut-off) is not automatic control.

13, for filling systems which have a modified cycle in the initial or closing part of a more or less prolonged period of operation.

39, for diverse fluid pressure containing systems wherein the filling means is controlled by a gas condition in the receiver.

83, for filling apparatus including testing or weighing receiver contents. 95, for filling apparatus including signals, indicators and the like which are responsive to level or pressure in the receiver.

138+, for filling systems with means to supply successive receivers including means for interrupting a cycle.

153, for automatic control of filling cycle by contents material.

155, for filling systems which cease to operate under emergency conditions.

156+, for filling systems wherein the filling means is triggered by the presence of the receiver.

184+, for filling apparatus arranged to cease operation after a predetermined number of cycles or after filling a predetermined number of receivers.

285+, for appropriate subclasses, wherein equilibrium of the system may be established or maintained by claimed means.

291+, for supply valves operated by receiver engaging means.

351+, for receiver actuated discharge means for establishing a flow path and subsequent flow of material.
