Abstract: ABSTRACT            The present invention relates to an apparatus and method for making sheets from reinforced elastomeric ribbon. The apparatus has a lead-in mechanism on which the ribbon is received for preliminary orientation. The apparatus also employs a trans-fix mechanism that incorporates a shuttle head which is supported by a primary carrier disposed over the assembly mechanism.  The shuttle head is capable of being protracted from its normal position over the assembly mechanism to a position over the lead-in mechanism where it is also engaged by a stabilizing carrier which assures precise orientation of the shuttle head during its operative movements with respect to the lead-in mechanism. So stabilized the shuttle head: engages and grasps the ribbon presented by the lead-in mechanism, raises the ribbon off the lead-in mechanism; retracts to position the ribbon above the assembly mechanism; and, accurately deposits the ribbon on the assembly mechanism. A guillotine mechanism severs the incremental strip deposited on the assembly table from the ribbon. After the: shuttle head disengages from the incremental strip the guillotine mechanism is moved out of contact with the incremental strip go that the incremental strip can be transferred laterally by an indexing mechanism to the degree required for receipt of a suc-cessive incremental strip without inadvertent interference between the strip, or strips, being indexed and the guillotine. To achieve indexing the assembly mechanism employs a continuous belt that is accurately indexed by a unique arrangement of inter-acting brake and transport clamps. For most purposes, successive strips will be deposited in contiguous lateral juxtaposition, and in order that the successive strips stick together a stitcher is provided to cycle a stitching roller along the abutting edges of successively deposited incremental strips.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved rotating drum dryer and/or mixer for drying or mixing materials on a continuous basis is dis-closed.  The dryer and/or mixer includes a rotatable drum having an inlet end for receiving materials and a forced air burner for directing a stream of heated gases axially through the drum.  A heat dispersing means such as an array of spaced deflecting bars is disposed downstream  from the source of heated gases.  The dispersing means provides the interior of the drum with a more uniform radial temperature distribution and minimizes the central high temperature zone normally associated with such drum dryers and/or mixers.          Minimization of the central high temperature zone results in lowered production of smoke and other noxious emissions by an operating dryer or mixer.

Abstract: ABSTRACT OF THE DISCLOSURE An automatic fuel-dispensing system is provided for dispensing fuel at unattended fueling sites includes a number of fuel pumps capable of dispensing differnet types of fuel.  A common control console is used to con-trol the operation of the fuel pumps and to record the data relative to the customer identification, site location and quantity of fuel used.  The con-trol console includes a card reader, and a customer inserts a card which uniquely identifies him into the reader, enters an odometer reading, and se-lects a pushbutton for the fuel pump from which he desires to obtain fuel. If a validity check of the card against preset validity check data fails, a red invalid panel indicator illuminates on the control console; and no pro-duct can be withdrawn from the selected dispenser.  If the inserted card pas-ses the validity checks, the odometer reading and customer identification data is stored in a RAM memory uniquely associated with the selected dispen-ser. The card then may be removed from the reader which is then ready for the next fueling operation for another customer, even though fuel in the meantime is being withdrawn from the first-selected dispenser.  Upon comple-tion of fueling, the customer hangs up the dispensing hose to turn off the pump, and the control console is signaled to indicate fueling is completed. The customer identification, quantity of product withdrawn, identity of pro-duct, and other optional output data then is automatically transferred under control of the control console to a teletypewriter or output interface for further processing.  A single card reader and control console may simultane-ously control the dispensing of fuel from all of the pumps which are con-trolled by it, and each of the transaction records are separately transferred to the output teleprinter or interface automatically without interference.

Abstract: ECG BASELINE SHIFT DETECTING  ABSTRACT OF THE DISCLOSURE In an electrocardiographic system there is a multielement electrode at each skin location for providing an ECG signal of negligible magnitude between elements because of the close spacing while the pair of elements are sufficiently separated so that the motion of one element is at least partially indepen-dent of the motion of the other; thus, events causing a baseline shift will also cause a difference in potential between the two elements of a multielement electrode.  That difference is detected by logical circuitry to produce a signal indicating baseline shift.
