Title: Switching system control arrangements
Inventor: BASSO RICHARD J
IPC: H04Q11/04
Filed: 1987-03-05
Granted: 1990-11-27
Abstract: SWITCHING SYSTEM CONTROL ARRANGEMENTS     Abstract Methods and arrangements for associating control messages received in the D-channel of an integrated services digital network (ISDN) line with the call control process to which the message relates are disclosed,  With ISDN, a single control channel, called the D-channel, can be used concurrently to control a plurality of calls.  As each call is initiated, a call control process and data structure including the unique identity of the call, are created.  The data structures associated with the same D-channel are linked together. When a control message including a given identity is received, the data structures associated with the D-channel conveying the message are searched in sequence until a data structure having the given identity is found.  The contents of this data structure are used to access the control process associated therewith.  When the search reveals no matching identity and the message is a call setup message, a new process and data structure are created.

Title: Machine for printing on articles by silk screening
Inventor: MEREDITH STEVEN A
IPC: B41F15/10
Filed: 1987-03-20
Granted: 1990-11-20
Abstract: Abstract In the course of continuous movement along a track that is essentially circular, articles undergoing an imprinting process are passed through a plurality of print stations, individual silk screen stencils at the stations being adjusted to the resulting changes in the position of the article that occur during the imprinting process as the article moves through the printing machine.  The articles can be arranged with their longitudinal axes either horizontal or vertical during the imprinting process.          It is also possible to introduce the articles into the machine with their longitudinal axes vertical, then move them into a position in which their longitudinal axes are horizontal and imprint them in such a position, and then bring the imprinted articles once again into a position in which their longitudinal axes are vertical so that they leave the machine in this position.

Title: Closed loop, programmable power and communication system
Inventor: BOWLING GEOFFREY N
IPC: G02B6/38
Filed: 1987-07-13
Granted: 1992-03-10
Abstract: ABSTRACT A power and communication system for a building, and particularly a residential dwelling wherein there are provided a plurality of receptacles throughout the building, each connected by a cable to a source, which may provide different voltages and either AC or DC. and having a control interface for selectively switching the desired power to each cable individually.  The control interface may also connect each cable to a selected signal transmission line, such as telephone, radio, TV., etc.  The cable includes a pair of power conductors and an optical fiber which transmits to and receives from the control interface light signals informing the control interface what power or communication connection is required for a particular receptacle and possibly at the same time providing signal messages to each recep-tacle.   The single optical cable can transmit an interrogating signal to the receptacle, which signal is transferred through a special plug and socket connection having a mating optical coupler to an appliance equipped with a microprocessor programmed for replying by way of light signals sent back to the interface through the same coupler and optical fiber.   The control interface is thus informed as to what power and communication connections the appliance requires and how the appliance should be subsequently monitored.  In order to allow the use of appliances which are not equipped with a microprocessor, the plug of such an appliance can be equipped with a retro-reflective element located to align with the coupler of the socket so that a reflected signal informs the control interface that the appliance must be supplied with power of conventional frequency and voltage.   In the disclosed system, the receptacles are not supplied with power until a suitable equipped appliance is plugged in or turned on, thus improving the safety of the power supply, and since only slightly modified  socket and plug combinations are used, the system and appliances are compatible with conventional outlets and appliances. Communication signals for telephone, TV. and monitoring systems can be transmitted through the same receptacles provided for power outlets.
