  • Patent number: 11241099
    Abstract: A cup holder for a seat of an auditorium or theater includes a cup receiving body and a mounting arm. The cup receiving body is configured to receive and support a cup therein. The mounting arm extends from the cup receiving body and includes a receiving portion and an attachment portion. With the mounting arm extending across a side portion of a seat back frame of a single seat, and with the receiving portion receiving a front portion of the seat back frame and the mounting arm extending from the front portion of the seat back frame to a rear portion of the seat back frame, the attachment portion of the mounting arm abuts the rear portion of the seat back frame, and the attachment portion is attached at the seat back frame to secure the cup holder relative to the seat back frame.

  • Publication number: 20210289943
    Abstract: A tablet assembly for a chair includes a mounting portion configured to mount at an arm rest of the chair, a tablet pivotally mounted at the mounting portion about a pivot axis, and a pivot limiting mechanism that selectively limits pivotal movement of the tablet about the pivot axis. The pivot limiting mechanism, when in a first state, limits pivotal movement of the tablet between a use position and a non-use position. Pivotal movement of the tablet is stopped at the non-use position by the pivot limiting mechanism when the pivot limiting mechanism is in the first state. The pivot limiting mechanism, when in a second state, allows for pivotal movement of the tablet further from the use position and beyond the non-use position to move the tablet further toward a side of the chair. The pivot limiting mechanism is selectively adjusted from the first state to the second state.

  • Patent number: 6992281
    Abstract: An Inductively Coupled Plasma (“ICP”) mass spectrometer is disclosed comprising a mass filter and a reaction/collision cell. Analyte ions and background ions having the same nominal mass to charge ratio are transmitted by the mass filter. The analyte ions selectively react with gas in the reaction/collision cell to form product ions having different mass to charge ratios. By measuring the intensity of the product ions the intensity of the analyte ions can be determined. According to less preferred embodiments background ions may be neutralised or reacted in the reaction/collision cell.
