  • Publication number: 20230094368
    Abstract: Apparatus 2 for dosing a liquid colour formulation into polymer includes a weighing platform 4 which is supported on a pair of load cells 6 which are, in turn, supported on a base 8. A reservoir 12 contains liquid colour formulation 14. A pump 16 is arranged to pump liquid formulation, via a tube 20, to an extruder or injection moulding machine. Above inlet 24 is a delivery pack 26 which includes a bag-in-a-box arrangement 28. The delivery pack 26 includes a transfer pump 36 associated with an outlet of the receptacle 32. A transfer pump motor 38 is arranged to be engaged with the transfer pump 36 and operated so that liquid formulation can be pumped from the receptacle 32 into reservoir 12 across an air gap 13 defined between the transfer pump 36 and the inlet 24 of reservoir 12. There is no pipe, tube or other conduit through which liquid formulation passes on travel between delivery pack 26 and reservoir 12.

  • Patent number: 7002698
    Abstract: A lift/tilt assembly for use in a semiconductor wafer processing device is set forth. The lift/tilt assembly includes a linear way comprising a fixed frame and a moveable frame. A nest for accepting a plurality of semiconductor wafers is rotatably connected to the moveable frame. The nest rotates between a wafer-horizontal orientation and a wafer-vertical orientation as it is driven with the movable frame by a motor that is coupled to the linear way. A lever connected to the nest provides an offset from true vertical for the nest when the nest is in the wafer-vertical orientation.

  • Patent number: 6672820
    Abstract: A transport system for manipulating a semiconductor wafer in a processing tool is set forth. The system includes a transport unit guide disposed within the processing tool for supporting a wafer transfer unit as the unit moves between a first position and a second position. The transport unit guide comprises a frame, a lateral guide rail mounted on the frame, and a series of magnetic segments arranged upon the transport unit guide proximate the lateral guide rail. The wafer transfer unit includes a tram translatably attached to the lateral guide rail and a wafer transfer arm assembly for manipulating the semiconductor wafer. An electromagnet is mounted on the tram in cooperative relation with the magnetic segments for moving the transfer unit along the guide rail. Actuators are used for controlling the position of the transfer unit and transfer arm assembly, and sensors are used for determining the position of the transfer unit and the transfer arm assembly.
