摘要： Each of a plurality of message terminal units (10, 12, 14, 16) has a keyboard (20) for entry of data, a visual display (22) for display of entered and received data, and a logic system (FIG. 4) for processing received and transmitted messages. Each unit stores in a CPU (52) a dedicated user terminal identification. Each transmitted message is annexed to a destination terminal identification and said user terminal identification (FIG. 5). Only a unit with a stored user identification identical to the destination identification in a transmitted message can receive and display transmitted messages. Upon receipt of a message, a terminal sends an automatic response to the sending terminal, which provides an appropriate indication to the sender. The receiver can send a manual acknowledgement (42) to the sender, which causes the message to be cleared from the sender's display. The units transmit messages via pulse modulation of a high frequency carrier over a supply power line (26) so that no special wiring is required. A unit can send messages to plural destinations and indicate which destination units have received the message. Optionally, a user can store plural incoming messages (FIG. 7) and selectively display same. Also, optionally, a unit can send its user's identification indicia, upon attempted entry thereof, to all other units which will compare the attempted identification entry indicia with their stored user identification indicia (FIG. 8) and indicate if the same indicia are already in use, thereby preventing two users from using the same indicia so as to insure privacy of transmission. A unit can be made to automatically send a fixed message upon receipt of any message, this feature being most useful to indicate a user's temporary absence.

摘要： A lead screw driven by a motor has a drive nut threadably connected to the lead screw for reciprocation therealong. The drive nut is rotationally restrained thereby limiting its movement along the axis of the lead screw. Three disk members each having an opening through their centers are positioned on the lead screw. The two outer disk members each have at least a pair of bearing members, such as ball bearings, positioned along a diameter of the disk on adjacent sides of the opening. A keeper member is positioned on the lead screw to sandwich the three disk members between the drive nut and the keeper member. Indexing members are positioned on the drive nut and the keeper member to maintain the diameters of the two outer disks, having the bearings mounted therein, orthogonal with respect to each other. A linear motion device is rigidly coupled to the keeper member such that rotary motion of the lead screw is translated to the linear motion device without flexure, eccentricities, or other undesirable movement of the lead screw being transmitted to the linear motion device.

摘要： Line broadening is eliminated in dry heat-developed films by using a development temperature which is higher than the manufacturer-recommended standard temperature, so that a much shorter development time can be used, and masking the edges of the film to prevent exposure thereof. The hot/short development cycle and the masking of the film edges substantially eliminate image smearing caused by emulsion shrinkage and migration.

摘要： An infrared RS 232 communication link protocol is particularly suited for correcting any errors introduced during a transmission of information. The information is transmitted from a transmitting station to a receiving station. Each of the stations has a control counter each of which toggles between a logic 0 and 1. The control counter for the transmitter and the receiver are phase locked so that all errors may be corrected. The receiver echoes each data bit back to the transmitter which compares the echoed data to the transmitted data. If there is a match, the transmission was successful. If there is no match, the data must be retransmitted. A retransmit control character RTXx is sent to indicate that the receiver should discard the previous character and prepare for a retransmission of the character having the error. Under the proper circumstances and if the counters are still phase locked, the receiver then discards the previously stored character and inverts the counter. If the receiver detects that it has received an erroneous character, such as one having multiple or no PPM pulses, the receiver will simply respond with the reject control character REJ. In such a case, the transmitter will respond with an RTXx which causes the receiver to discard the previously stored character and invert the counter.
