A system holds a roll of film that includes a core and film wound around the core. The system includes a rod having an outer diameter that is smaller than an inner diameter of the core, a proximal wing located on the rod and configured to rotate about the rod, and a distal wing located on the rod and configured to rotate about the rod. Each of the proximal and distal wings includes contact surfaces configured to contact diametrically-opposed locations on a side of an inner surface of the core and non-contact surfaces that span between the contact surfaces of the wing. The non-contact surfaces of the wings do not contact the core if the core has a cylindrical shape. The distal wing is capable of rotating around the rod independently of the proximal wing.

A system for opening and closing a mixing manifold includes a drive motor, a cam plate, and a valving rod connector. The drive motor imparts movement in first and second directions. Movement imparted in the first direction causes the cam plate to move linearly in a third direction and movement imparted in the second direction causes the cam plate to move linearly in a fourth direction. Movement of the cam plate in the third direction causes the valving rod connector to move linearly in a fifth direction and movement of the cam plate in the fourth direction causes the valving rod connector to move linearly in a sixth direction. Movement of the valving rod connector in the fifth direction causes retraction of a valving rod of the mixing manifold and movement of the valving rod connector in the sixth direction causes extension of the valving rod.

A fluid mixing device includes a fluid mixing unit, a concentration measurement unit, a mixing ratio control unit controlling a mixing ratio of different fluid components in the fluid mixing unit based on a concentration of a mixed fluid measured by the concentration measurement unit, a flow rate measurement unit, and a flow rate control unit controlling a flow rate of the mixed fluid based on the flow rate of the mixed fluid measured by the flow rate measurement unit. The concentration measurement unit, the flow rate measurement unit, and the flow rate control unit are arranged on the downstream side of the fluid mixing unit. A flow passage of the concentration measurement unit, a flow passage of the flow rate measurement unit, and the elastic tube of the flow rate control unit are arranged to extend along a flow passage axis on a line with each other.

A mixing machine includes a head extending over a bowl receiving location, the head including a downwardly extending rotatable output shaft for receiving a mixer tool. A drive train including a motor having an output operatively connected to drive a planetary gear system that effects rotation of the rotatable output shaft about its axis and orbiting of the shaft axis about another axis. A control system includes a master control unit and a slave control unit, the master control unit connected with a first sensor located along the drive train between the motor and the planetary gear system, the slave control unit connected with a second sensor, wherein both the slave control unit and the second sensor rotate with a part of the planetary gear system, wherein the master control unit and the slave control unit are configured for wireless communication with each other.

A wireless sensor measures properties of a substance and transmits the properties to a remote wireless receiver. The wireless sensor can be fully enclosed within a container containing the substance, allowing remote monitoring of the properties of the substance without compromising integrity of a closed system.

A liquid measuring beaker is suitable for measuring an amount of a liquid required in a liquid mixing process. The liquid measuring beaker includes a shell and an adjusting partition. The shell defines a reservoir having a volumetric capacity, in which the shell has a first opening passing through a bottom of the shell. The adjusting partition is vertically movable in the reservoir for adjusting the volumetric capacity, in which the adjusting partition has a second opening passing through the adjusting partition.

A longitudinal sealer includes a housing, an arm, and a heating element. The housing is configured to be installed in a foam-in-bag system. The arm is movably coupled to the housing. The heating element has a leading edge exposed through an exterior surface of the arm. A position of the arm with respect to the housing is controllable so that the arm is movable between a first location where the leading edge of the heating element is not in contact with a film in a film path of the foam-in-bag system and a second location where the leading edge of the heating element is in contact with the film in the film path of the foam-in-bag system.

Embodiments provide mixing methods, systems, apparatuses, devices and assemblies that enable high-accuracy mixing of two or more substances in a manner that controls the concentrations of one or more substances in the resulting mixture. A mixing apparatus (100) may enable mixing of two or more substances at a mixing zone or conduit (112). The mixing apparatus may include one or more sensors (120) for detecting one or more characteristics of the mixture during the mixing process. The sensors may detect the mixture characteristics continuously, at intervals or as prompted by a user. The mixture characteristics may be used, in the sensors or in control circuitry, to generate an indication of the concentration of a first constituent substance in the mixture. Based on the detected concentration, the mixing apparatus may automatically adjust a supply of the first substance to the mixing zone or conduit (112).
