Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to the arrangement of a switching network intended to be used within an electrical utility station  switchyard, which improves the security of power delivery to various loads while at the same time allowing a reduction in the number of required circuit breakers and related gear.  The invention is a switching network comprising six conducting branches, each branch containing at least one switching means such as a circuit breaker.  The branches are connected at their ends so as to form four 3-sided rings, each branch forming a side of and being shared by two of the rings.  As a result, four triple-connected nodes are formed at the end connection points of the branches while the connections between adjacent pairs of switching means within a branch form double-connected nodes.          These nodes serve as points for connection thereto of source/load elements, and each node is isolatable by the operation of a maximum of three of switching means.

Abstract: ABSTRACT         This apparatus is for use in the launching of battered leg jackets for offshore platforms.  The jacket is transported on at least one barge resting on its lower battered legs and, during launching, the apparatus guides the jacket by its lower battered legs to maintain the center line of the jacket on the launching center line.  The apparatus uses a pair of dollies on a beam, and at least two beams on a barge.          The beams are mounted transverse to the launching center line.  The dollies can move along the transverse beam and position coordinating means are used to control the relative positions of the dollies on each beam such that the two dollies are maintained essentially the same distance from the launching center line with one dolly on either side of the launching center line.  When either dolly is moved, the other dolly on the same beam will move the same distance in the opposite direction.          The dollies are adapted to maintain the battered legs on top of the dolly and the leg slides through the guide on top of the dolly (thus any movement of the dolly relative to the leg is along the length of the leg).  As the legs stay on top of the dollies and as the dollies in a pair stay the same distance from the launching center line, the legs are maintained the same distance from the launching center line and the jacket is kept centered as the legs slide through the dollies during launching.  For example, if the jacket is launched small end (top) first, the distance between the legs will increase as the legs slide through the dollies, and the dollies on each transverse beam will move apart.

Abstract: CLOSED LOOP EXHAUST GAS RECIRCULATION CONTROL SYSTEM          ABSTRACT OF THE DISCLOSURE A closed loop exhaust gas recirculation (EGR) control system for an internal combustion engine having an intake system, an exhaust system, a throttle disposed within the intake system for controlling air flow therein, a conduit coupling the exhaust system to the intake system for supplying exhaust gas back to the intake system for controlling the generation and emission of oxides of nitrogen and for improving drivability and avoiding engine roughness. The EGR control system of the present invention includes a first memory pre-programmed with a look-up table of optimal EGR values indicative of EGR valve position or the like determined as a function of engine speed and throttle position and a second memory pre-programmed with the look-up table of optimal EGR values determined as a function of engine speed and absolute manifold pressure The actual operating parameters of engine speed, throttle position and absolute manifold pressure are accurately sensed and stored as multi-bit binary numbers or words indicative thereof. The most significant bits (MSB) of the words are used to address the first and second memory while the least significant bits (LSB) of the words are used to perform a double linear interpolation of the accessed values to compute accurate first and second EGR values. The second EGR value is substracted from the first EGR value to determine a difference indicative of the current EGR valve error. A previously computed and stored EGR error value used to determine the last valve position adjustment is then substracted from the current EGR error value to determine the total change in error value required to correct the EGR valve position at the next adjustment. A fractional portion of the total change in EGR error value is then applied to the previously stored EGR error value to update same so as to avoid rapid or abrupt adjustments in the valve position so as to avoid engine roughness etc. The updated EGR error value is converted into a control signal which is used to adjust the position of the EGR valve at the next scheduled valve adjustment time so as to regulate EGR flow as desired.

Abstract: METHOD OF MAKING LAMINATED WINDSHIELDS  ABSTRACT OF THE DISCLOSURE         A method of making laminated windshields is disclosed.          Brackets of glass of oblong shape are cut from a continuous glass ribbon manufactured by a "Float" process in such a manner that the brackets have drawlines associated therewith running across the shorter dimension of the bracket.  The brackets are cut, formed into pairs, bent as pairs, and laminated as pairs to produce completed windshields which have the drawlines of the glass aligned vertically, i.e., in the direction from the top to the bottom of the finished windshield.  This orienta-tion of the glass reduces the drawline distortion observable when the windshield is in place in the vehicle.

Abstract: DISPOSABLE CENTRIFUGAL BLOOD PROCESSING SYSTEM   Herbert M. Cullis Abstract of the Disclosure A continuous flow centrifugal processing system for separating whole blood into fractional components in-cludes a centrifugal separator unit having a molded bowl-shaped outer shell dimensioned to fit within a rotatably-driven casing on an associated centrifuge apparatus.  A bowl-shaped inner shell disposed within the outer shell forms therewith a thin separation channel radially spaced from the axis of ro-tation wherein fractions are separated from the whole blood under the influence of centrifugal force.  A rotating seal carried on the processing chamber between ports in the chamber and the non-rotating portions of the system.  The outer shell includes a relatively thin side wall portion which is inwardly biased toward a side wall portion on the inner shell when seated in the casing.  A plurality of projections on the side walls limit inward deformation of the outer shell to maintain a very close concentric spacing between the shell members to facilitate rapid separation of blood flowing through the chamber.          By reason of the shell members being molded, the processing chamber can be economically produced in large quantities for disposable one-time use.

Abstract: SHUNT TRIP MECHANISM FOR A CIRCUIT INTERRUPTING DEVICE ABSTRACT: A shunt trip mechanism includes a ratchet facility added to a self-contained, line potential stored-energy operating mechanism of a circuit interrupting device. Operation of the ratchet facility releases the stored energy to operate the device. A portion of the ratchet facility may also be operated to reset the device if it has previously been operated by either the shunt trip mechanism or the operating mechanism's current-responsive elements. The main portion of the shunt trip mechanism is at ground potential and is mechanically tied to and operates the ratchet facility by a movable insulated strut. The strut is moved by the shunt trip mechanism upon the occurrence of an event such as transformer overpressure. A ground level handle may be operated to reset the device whether it was operated by the operating mechanism or the shunt trip mechanism.
