Abstract: A method of providing multi-switch business  group (MBG)  services  at  each  of  a  plurality  of  locations  is described.   The MBG services can be provided for calls made from a calling party served by an originating switch at one location to a called party served by a terminating switch at a location serviced by an inter-exchange carrier (IEC). When the calling  party  goes  off-hook,  a  determination  is  made  of whether the call is made from a centrex line.   Digits dialed by the calling party are then collected at the originating switch.   A determination is then made of whether the dialed digits contain an access code indicative that the call is to be routed to one of the plurality of locations which is served by an IEC.   If the call is to be routed via an IEC,  the initial address message  (IAM)  required for the IEC call,  is modified to include MBG service information.  This will permit MBG services to be offered between the calling party and the called party over public CCS7 trunks routed via an IEC.
Patent CA-2174200-C (CA)
Inventor: RICHARDSON HUBERT JR
IPC: F04F5/50
Filed: 1996-04-15
Granted: 1998-12-22
Abstract: A scroll compressor is provided with a check valve which is disposed in a suction chamber adjacent a suction port opening.  The check valve provides fast response and enhanced operating characteristics for preventing reverse refrigerant flow and reverse scroll operation during compressor shutdown.  During normal compressor operation the check valve is open to allow communication of refrigerant into the suction chamber where the refrigerant is acted upon by the scroll mechanism and discharged through a discharge port.  A positive pressure differential exists between the discharge port and the suction port which unimpeded causes reverse scroll operation upon compressor shutdown.  The positive pressure condition in the suction chamber forces the check valve to pivot to a closed position whereby it covers and substantially seals the suction port.  By preventing reverse refrigerant flow through the suction port the check valve effectively eliminates the pressure differential and thereby prevents reverse scroll operation.
