Abstract: A multi-medium store-and-forward exchange apparatus is connected to a plurality of line networks to convert a data received from a data originator terminal into another sort of data corresponding in attribute to another sort of line net-work and to transmit the converted data to a destination terminal.   When  the destination terminal does not handle the data to be transmitted from the data originator terminal, the store-and-forward exchange apparatus converts the data into another sort of data which can be handled at the destination terminal, and then transmits the converted data from its network controller in the apparatus.  Further, an identifica-tion data of a terminal is registered to which a data arrival is announced at the time of the data reception in the form of a medium (voice, character or picture data) message previously prepared in the store-and-forward exchange apparatus.  Identi-fication data are allocated to individual system users, each user determines a terminal to be used depending on the at-tribute of the data to be transmitted, and the data to be transmitted is transmitted to the terminal.

Filed: 1991-05-10
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for deaerating a suspension of solids in a liquid such as, for instance, papermaking stock.  The suspension is flashed in a vacuum tank connected to a condenser.  The vapor released when the suspension is flash cooled in the tank is condensed into an absorption liquid having a higher temperature but a lower vapor pressure than that of the released vapor on a heat exchange surface of the condenser.  The flash cooled suspension is used as the cooling medium in the condenser.  The diluted absorption liquid is regenerated in an evaporator and recirculated to the condenser.  The vapor released in the evaporator can be condensed to heat the suspension further or for other suitable heating purposes.

Patent CA-2052104-A1 (CA)
Inventor: HAYS DAN A
IPC: G03G15/08
Filed: 1991-09-24
Abstract: Selective coloring of bi-level latent electrostatic images is obtained through a combination of 1) a scavengeless development nip enabled by an AC biased wire in self-spaced contact with a toned donor roll, 2) a belt image receiver such as either a photoreceptor or electroreceptor without a [substrate and; ground plane and 3) an array of addressable, stationary electrodes positioned behind the belt in alignment with the AC biased wire. Selective coloring of the electrostatic image is obtained by selectively DC biasing addressable, stationary electrode structures forming electrode arrays positioned behind the belt. By controlling the level and timing for applying a DC bias to each electrode segment, the developability can be switched on and off with x,y addressability in the plane of the electrostatic image. Thus, with a system having resident multi-colored development systems, different areas of the electrostatic image can be developed in a single pass with different colors and perfect registration simply by controlling the DC'electrical signals to the electrodes.
