Abstract: ABSTRACT OF THE DISCLOSURE    In a thermal transfer recording method for use in a recording apparatus using a roll of recording paper of an ordinary paper material wound about a core and a strip of ink ribbon would about an ink ribbon feeding roll, recording is effected by means of a thermal head while both the recording paper and the ink ribbon are transported forwardly in the superimposed state.  During transportation of the recording paper and the ink ribbon after the recording, they are parted away one from the other and only the recording paper is transported to an automatic cutter by means of which a part of the recording paper on which recording has been effected is cut off.  After completion of cutting operation an unused parts of the recording paper and the ink ribbon are transported backwardly to the position where the leading end of the thus returned recording paper is located in the proximity of the thermal head.

Title: Reinforced delta-wing blade for wind turbine

Abstract: "REINFORCED DELTA-WING BLADE FOR WIND TURBINE"          ABSTRACT OF THE DISCLOSURE              The flat-plate type wind turbine rotor blade comprises a rigid spoke having a single thin flexible skin associated therewith.  The skin is formed to provide a delta-wing and a flap extension.  The delta-wing and the flap extension are angularly disposed at about 25° to each other.  The spoke lies along the junction of the delta-wing and the flap extension.  A substantially rigid peripheral member extends along the margin of the skin.  The peripheral member and the spoke are joined to provide a frame to which the skin is secured.  Arrays of parallel re-inforcing rib members extend between the spoke and the peripheral member. These rib members are mounted on the pressure surface of the skin. The ribs on the delta-wing are positioned at an angle of about 60° from the axis of the spoke, the ribs on the flap extension are positioned at an angle of about 75° from said axis.  They therefore coincide with the main flow paths of the air flow over the blade surface.               The blade is reduced in weight and cost relative to a conventional double-walled blade or a single skin blade of a thickness sufficient to eliminate the need for reinforcing members.

Title: Local modulated carrier data network with a collision   avoidance protocol

Abstract: LOCAL MODULATED CARRIER DATA NETWORK WITH A COLLISION AVOIDANCE PROTOCOL     Abstract of the Disclosure There  is  disclosed  an  improved modem for a single frequency, modulated RF carrier local data network for a distributed data processing system and a method for line acquisition  and  contention  resolution.    The  protocol established for line acquisition and contention resolution is  implemented by  a modem controller.   The controller causes the receiver section to listen for foreign carriers to  determine when the line is busy.  When the client device of  the modem desires to send a data packet to another unit, the modem controller causes the receiver to listen for a certain pre-burst period and then causes the transmitter to send a non data bearing burst of RF carrier out on the line and simultaneously causes the receiver to listen to the line for interference beating, i.e. changes in amplitude on the line which indicates another unit is requesting  the  line.    To  insure  beat  patterns,  the frequency of the burst  carrier  is  swept over a range during the burst.  If a contention is found, a resolution thereof  is  made  utilizing  a  random  delay and  retry protocol.   After  the  burst,  the controller causes  the receiver to listen to the line for other carriers.   If none are found, the controller causes the transmitter to transmit a data packet preceded by a preamble of 100% modulation level RF carrier.  During the preamble period, all receivers in the system set their respective automatic gain   control   levels   to   a  level   for   comfortable reception.  The gain level so established depends upon the strength of the received signal.  This amplification level is maintained throughout the entire data packet.  In this manner,  the transmission line is acquired prior to the transmission  of  data  packets,   thus  preventing  the collision of data packets.  In other local data networks, data packets may collide since the transmission line is not acquired prior to the transmission of data packets.
