Abstract: A B S T R A C T                    "Polarography"       The determination of the concentration of compounds such as CO2 having an influence on the pH of a medium during polarography is described.  Characteristics of polarograms when obtained in unbuffered electrolytes (the polarogram plateau slope position of the upper knee and half-wave potential thereof) are pH-sensitive. These can be detected electronically and signals processed to provide a measure of such concentrations.      In one preferred embodiment (Figure 2) a miniature pO2 polarographic sensor has cathode channels (A) and (B) biased respectively at -750 mV and -950 mV. The output of channel (A) provides pO2 as in normal polarography.  The output of (B) is divided (6) and further corrected for PO2 (8,10) to provide pCO2.      The apparatus is especially useful For simultaneous pO2, pCO2 monitoring in physiological fluids without the need for a separate pCO2 sensor.

Abstract: Abstract of the Disclosure The method of achieving hemostasis,  inhibiting fibroplasia,  and promoting tissue regeneration is described wherein a chitosan solution, or chitosan in various solid forms is placed in contact with the tissue wound.  The chitosan forms a coagulum which prevents bleeding and negates the  formation of  a  blood  clot  thereby preventing  the formation of fibrin strands.  The prevention of the formation of fibrin strands prevents the proliferation of fibroblasts and the synthesis of collagen thereby allowing the promotion of  normal  tissue  regeneration.   The  process  described hereinabove results in wound healing with minimal scar formation.

Abstract: SPECIFICATION HEAT PIPE APPARATUS                  ABSTRACT OF THE DISCLOSURE    A heat pipe apparatus for heating application is disclosed.  The apparatus comprises a main tube filled with a heat transfer or working fluid, a heat source extending through the main tube to vaporize the working fluid, a secondary tube communicated with the main tube by conduit pipe means to define a closed space in the apparatus in which the working fluid undergoes the cycle of vaporization and condensation to give off heat to the surrounding air passing upwardly through evenly spaced fins attached to the main and secondary tubes.  The main and secondary tubes are arranged in parallel with one another and disposed substantially horizontally with the conduit pipe means extending upwardly so as to allow the air to pass upwardly by natural convection through the fins on each tube as the air receives the heat therefrom.  In a preferred version, the fins on secondary or upper tube are spaced along the length thereof at a wider spacing than those on the main or lower tube such as not seriously impede the upward flow of the air by natural convection through the fins on the lower tube, thus making the best of the main tube to efficiently release as much amount of heat therefrom and as well to release additional amount of heat from the upper tube in order to increase the total amount of heat released from the  whole apparatus.

If the determined number of documents is two, the number of plural identical copies made is equal to the number of copy sets made, but not more than 14, and the document set is circulated not more than three times for up to 14 copy sets. If the determined number of documents is three, the plural number of identical plural copies made is four, and all documents other than the first document copied are copied only once in each document set circulation.

The buffer memory includes an outlet means for connection with the equipment controller and the overall control unit is such that the time necessary to transfer data from the control unit to the equipment controller is directly related to the data transfer characteristics of the buffer memory and the equipment controller.  Data transferred from the floppy disk to the buffer memory occurs in anticipation of the requirement of such data by the equipment controller and is available essentially immediately when required by the equipment controller. such a control unit allows information to be read from the disk drive independent of the information being required by the equipment controller whereby the random access memory capability of the disk drive is fully utilized.
