Abstract: TIME DIVISION DIGITAL COMMUNICATION SYSTEM                ABSTRACT                 A time division digital communication system which does not require a common control unit for accomplishing interconnections, having a plurality of modular switching units.  The switching units are identical and each unit has its own port circuits to which subscriber lines and/or trunks may be connected, service circuits, a time slot interchange and a microprocessor control and timing unit.  The switching units are in direct communication via separate send highways, one for the port circuits and the other for the service circuits of each switching unit.  The microprocessors of each switching unit are also in direct communication by way of control lines.  The inter-switching unit send highways are connected to separate channels or groups of memory locations in the time slot interchanges of each of the switching units.  By selective listening to receive highways connected to the output of the time slot interchanges, any port or service circuit, whether in its own switching unit or any of the other switching units, can be interconnected.  These interconnections are made under microprocessor control on the basis of events such as off-hook conditions and dialed digits from the ports, rather than by central or call processing.  The switching of calls is non-blocking, as any port can be connected to any one or more of the other ports or service circuits at all times.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for the separation and isolation of AHF, fibro-nectin and von Willebrand's ristocetin cofactor from blood plasma by adding a sulfated mucopolysaccharide to blood plasma to a con-centration of from about 0.05 to about 0.4 mg/ml of plasma, cool-ing the plasma to 0°C - 15°C, centrifuging the plasma to isolate a precipitate which forms and then removing the AHF-rich super-natant liquid from the precipitate.         The precipitate is washed in a slightly basic solution of dilute salts and then dissolved in a buffered solution of chao-trophic salts of the Hofmeister series having an ionic strength from 0.01 - 1.  Fibronectin is separated by chromotographic means from the dissolved precipitate which contains fibronectin and fibrinogen.         The dissolved precipitate may also be applied to a glass or plastic column containing a 4% agarose gel (eg. "Sepharose"?B or"Biogel"??-15m) in a 0.25 molar solution sodium phosphate titrat-ed to pH 7.0 with any base, preferably TRIS.  The von Willebrand's ristocetin cofactor elutes in the void volume of the column, where-as the fibronectin-rich fraction elutes later.  Both fractions may be collected and concentrated.         In a preferred embodiment, 0.20 mg of sodium heparin per milliliter of human plasma is employed with the heparinized plasma solution cooled for 3 hours at a temperature of 2°C - 4°C.     *    Trademark **   Trademark

Abstract: IDLE ADJUSTMENT CONTROL AND SCULPTURED TWIST GRIP THROTTLE CONTROL HANDLE FOR A MARINE PROPULSION DEVICE           ABSTRACT OF THE DISCLOSURE         A marine propulsion device comprises a marine propulsion unit including an engine and a rotatably mounted propeller which is operatively connected with the engine.  The engine has a throttle movable between an idle position and an advanced position.  A steering tiller is attached to the marine propulsion unit, and a throttle grip having an exterior gripping surface is rotatably attached on the steering tiller.  A throttle linkage assembly operatively connects the throttle grip with the throttle for moving the throttle between the idle position and the advanced position in response to rotation of the throttle grip. An idle adjustment assembly is carried by the throttle grip and is operatively connected with the throttle linkage assembly for adjusting the low operational engine speed above the true idle speed of the engine.  A portion of the idle adjustment assembly protrudes outwardly from the sides of the exterior gripping surface to permit the operator to operate the idle adjustment assembly without removing his or her hands from the throttle grip. The gripping surface of the throttle grip is contoured to include a first surface area spaced generally at a first radial distance from the rotational axis of the throttle grip and a second surface area which is spaced angularly from the first surface area with respect to the rotational axis and generally at a second radial distance from the rotational axis which is different from the first distance.  The operator is thus able to judge the approximate position of the throttle by visual and/or tactile reference to the contoured throttle grip.

Abstract: IMPROVED METHOD OF DECARBURIZING MOLTEN METAL                    ABSTRACT OF THE DISCLOSURE           An improved method of refining molten metal is disclosed comprising the steps of injecting a mixture of oxygen and an inert gas below the surface of molten metal at a high oxygen to inert gas ratio while utilizing from about 2.5 to 12% of the injected inert gas to shroud the remainder of the injected gaseous mixture.  The oxygen to inert gas ratio is progressively decreased as the carbon content in the molten metal decreases and the temperature of the molten metal increases.  The improvement of the present invention comprises supplying dry air to the remainder of the injected gaseous mixture in a quantity sufficient for the nitrogen in the dry air to fulfill the inert gas requirements for the remainder of the injected gaseous mixture, and for the oxygen in the dry air to fulfill at least a portion of the oxygen requirements for the injected gaseous mixture.

Abstract: ABSTRACT         The disclosure is directed to an abrasive grind-ing machine particularly suited for the removal of slag surrounding the edges of metal workpieces torch-cut from flat stock.  The grinding machine includes a longitudinal conveyor (11) that is tilted about a longitudinal axis so that one longitudinal edge is lower than the other.  A fence (25) is positioned along the lower edge to retain and guide workpieces (26) as they are carried forward by the conveyor (11).  A grinding head (12) consists of an endless grinding belt (21) carried and driven by upper and lower parallel rollers (22, 23).  The lower contact roller (23) is positioned in spaced relation to the upper flight (17) of the conveyor  (11).  The contact roller (23) is positioned with its  rotational axis at a predetermined acute angle  (B) measured clockwise from the the forward line  of  conveyor  movement.   The  rollers  (22,  23)  are driven so that the grinding belt moves toward the fence (25),  creating a major component of movement perpendicu-larly toward  the  fence  (25)  and a minor  component of movement in the direction of conveyor belt (11) movement. In an alternative embodiment, the contact roller (23) is positioned at an acute angle (B) that is measured coun-terclockwise from the line of forward conveyor (11) move-ment.  This produces a major component of movement perpen-dicularly toward the fence (25) and a minor component of movement opposite the direction of forward conveyor (11) movement.   In  either  case,  the  grinding head  (12)  is constructed and positioned so that it provides the addi-tional function of a pinch roller, permitting small work-pieces (26) to be efficiently and uniformly ground.

Abstract: ABSTRACT OF THE DISCLOSURE           An adaptor for use in driving a pipe into the ground by a ground piercing tool, which adaptor is arranged to be driven by the piercing tool.  The adaptor consists of a three piece cylindrical unit held together by two garter springs, A tapered conical bore, formed in the adaptor, has a slope comparable with the slope formed on the forward end of a ground piercing tool used therewith.  A portion of the adaptor is arranged to enter the end region of a pipe being worked upon, and a circumferential shoulder is formed on the adaptor, for engagement with the end of the pipe.  Impact action upon the piercing tool not only wedges the adaptor into tight engagement with the inner region of the pipe, but also results in driving action upon the pipe by reason of the circumferential shoulder being in engagement with the pipe end,  When the piercing tool is subjected to reverse impact action, it is released from the adaptor, and the latter is collapsed by action of the garter springs, so that it can be withdrawn from engagement with the pipe.
