Patent CA-2020240-C (CA)
Title: Semi-automated operator assistance telecommunication calls
Inventor: DORST GARY L
IPC: H04M3/60
Filed: 1990-06-29
Granted: 1994-05-24
Abstract: Abstract An operator assistance call handling arrangement is disclosed featuring the use of an intelligent telecommunications station (intelligent phone) for the collection and transmission of call data to an operator assistance system for setting up a call without the intervention of an operator. The intelligent phone is equipped to handle CCITT (International Consultative Committee for Telephone and Telegraph) standard Layer 3 (Q.931) call control messages defined for message associated user-to-user information (MA-UUI). The operator assistance system is part of a central telephone office switching system, and is connected to the intelligent phone via an integrated services digital network (ISDN) basic rate interface (BRI). For station-to-station (station) collect calls, person-to-person (person) calls including collect and calling card calls, and bill-to-third party calls, a calling (back) party enters information identifying the class of charge (COC) and other call data at the intelligent phone, which formats the information into a user-to-user information element (UUIE). The intelligent phone then places the UUIE comprising the call information into a Q.931 SETUP message and sends the SETUP message over an ISDN D-channel to the switching system comprising the operator assistance system to set up an ISDN B-channel call between the back party and a called (forward) party. By utilizing the COC information, connections for collect, person and bill-to-third party calls are set up without the intervention of an operator. Later, when the operator assistance system seizes an operator position to service the call after the call has been answered by the forward party, the call data is automatically displayed for the operator. A time and charges information delivery arrangement is also disclosed utilizing an intelligent telecommunications station (intelligent phone) for displaying that information after a termination of a call. The intelligent phone is equipped to handle CCITT (International Consultative Committee for Telephone and Telegraph) standard Layer 3 (Q.931) call control messages defined for message associated user-to-user information (MA-UUI), and is connected to a central telephone office switching system via an integrated services digital network (ISDN) basic rate interface (BRI). After an operator assistance call is terminated, the operator assistance system that processed the call sends a Q.931 SETUP message to the intelligent phone over an ISDN signalling channel (D-channel). The message includes a data block, comprising time and charges information. When the intelligent phone receives the message, it ignores the call setup request, and simply displays the information sent in the message. Thus, without any action by an operator, a public telephone customer receives time and charges information for the terminated call, without establishing a new call (B-channel call) between the operator assistance system and the intelligent phone.

Title: Clear-out apparatus for a coin chute
Inventor: GOODRICH ROBERT RAY
IPC: G07F1/04
Filed: 1991-01-23
Granted: 1996-11-19
Abstract: A coin chute includes a coin entrance, clear-out apparatus, coin processing apparatus, a return chute and a coin ejector. The clear-out apparatus is positioned between the coin entrance and the coin processing apparatus. It comprises a cavity for trapping unwanted material stuffed into the coin entrance and a pair of sidewalls (inner and outer) that move in response to the operation of the coin ejector. A deflector plate, positioned within the cavity, assists in trapping the unwanted material. The outer sidewall permits trapped material to fall into the return chute while the inner sidewall pushes this material into the return chute. The coin ejector includes an actuator that is operatively connected to the sidewalls of the clear-out apparatus by a helical spring whose restorative force is sufficient to urge material trapped within the cavity into the return chute, but not sufficient to damage the coin ejector when excessive force is applied to the actuator.

Title: Diagnostic system for textile dyeing apparatus
Inventor: COX STEVEN WAYNE
IPC: G06F11/22
Filed: 1991-02-14
Granted: 1996-09-10
Abstract: A diagnostic system checks the major hardware components in a pattern control system used in a textile dyeing apparatus. The system includes bypass logic circuitry which permits selective bypassing of either the look-up tables, stagger memories, or both the look-up tables and the stagger memories in the pattern control system.  The diagnostic system checks the look-up tables in the pattern control system to assure that the address lines for the look-up tables operate properly.  A prime number pattern is loaded into the look-up tables such that each address location for each look-up table will have a different piece of data.  The look-up tables are then read in address sequence and the output thereof compared with a previously stored prime number pattern to determine whether any errors arose.  The system further checks the firing times produced by the gatling memory section of the pattern control system by simulating a machine speedup and checking for the onset of machine optimum speed and machine overspeed.

Patent CA-2058316-C (CA)
Inventor: TRUDEAU ALLEN EDWARD
IPC: B29C31/08
Filed: 1991-12-23
Granted: 1998-10-27
Abstract: A bi-functional transfer foot that is structurally configured and operative to provide automated handling of preimpregnated composite materials.  The transfer foot includes a valve member having a knock-off stem movably mounted in a housing, a solenoid valve and fluid fine interconnection to vacuum and pressure sources, and a control subsystem for regulating the operation of the transfer foot.  The transfer foot is bi-functional for "ON" and "OFF" operation. A control signal issued by the control subsystem turns the transfer foot "ON" wherein vacuum forces causes a first displacement of the valve member within the housing to provide a vacuum force for engaging and retaining the tacky surface of preimpregnated composite plies.  Termination of the control signal causes the solenoid value to exert biasing forces to return the transfer foot to the "OFF" state wherein the transfer foot utilizes forces to cause a second displacement of the value member within the housing that provides a  mechanical force via the knock-off stem to disengage and release the tacky surface of preimpregnated composite plies.  A multiplicity of bi-functional transfer feet may be arranged in an array to define automated material handling apparatus for preimpregnated composite plies. Individual transfer feet may be automatically, selectively, activated to form predetermined combinations to match the wide variety of sizes and shapes or patterns of preimpregnated composite materials pre-cure processed via automated composite material manufacturing systems.

Abstract: A lining material for pipe lines, especially those buried in the ground such as sewage pipe lines and a process for providing such pipe lines therewith are disclosed, which material comprises a flexible tubular film, a resin-impregnated sheet covering the outer surface of the flexible tubular film, and a tubular covering material having a strong resistance to tensile force. The sheet may be constructed by several units of sheet fractions arid is overlapped in both lateral end portions so as to be slidable each other in opposite directions to form a tubular sheet. The lining material is applicable for repair/and reinforcement to the inner surface of a pipe line having damages portions. According to the process of this invention thermocuring of the lining material applied onto the inner surface of a pipe line can be carried out by moving a nozzle for jetting pressurized steam from one end to the other end of the pipe line without applying high pressure to the pipe line. Thus, the present invention is particularly suited for applying a lining material to a superannuated sewage pipe line or general sewage pipe lines having damaged portions.
