Title: Method of and apparatus for sealing pressurised ampoules
Inventor: RASBRIDGE HUGH
IPC: B65B7/16
Filed: 1981-09-07
Abstract: Ampoules (23-25) which have been filled at a filling station are conveyed by a conveyor belt (4) with their axes substantially vertical and at a sealing station are tilted out of the vertical (25) and located so as to present their necks to the beam of laser sealing means. Continued movement of the conveyor belt restores the now sealed ampoule to its upright position.

Title: Digital-to-analog converter providing voltage reference output for bipolar offset
IPC: H03M1/00
Filed: 1982-04-02
Abstract: In a digital-to-analog converter, a ground referenced constant voltage reference output signal is provided to facilitate the generation of a bipolar offset current of a magnitude equal to the most significant bit switch current and thereby effect a half-scale level shift of the analog output. The circuit includes a constant current source, a differential amplifier, and a feedback resistance for conducting the constant current and thereby establishing the reference voltage at a voltage reference output terminal. A bipolar offset resistor is coupled between this terminal and the analog output current terminal. A second differential amplifier maintains the analog output current terminal at virtual ground potential. The magnitude of the bipolar offset resistor is selected whereby an offset current equal in magnitude to the most significant bit switch current is provided to the analog output current terminal. An output resistor is coupled between the output of the second differential amplifier and the analog output current terminal for generating a half-scale level shifted analog output voltage at the output of the second differential amplifier.
