Abstract: AUTOMATIC CONTROL SYSTEM               FOR ELECTRIC PRECIPITATORS               ABSTRACT OF THE DISCLOSURE        In an adaptive type of control for precipitators, the current reference ramp signal is compared with a precipitator current signal to produce a phase reference signal which is combined with sawtooth waves to produce a first train of pulses.          In a spark detector, signals proportional to electrode potential are differentiated, and the differentiated output is integrated.          The integrator output, if in excess of a reference potential, triggers a spark pulse of predetermined width and amplitude.  The spark pulse, in addition to causing a predetermined small set back of the ramp signal, is integrated to produce a turn-off and recovery signal having a rapid excursion and subsequent slower return excursion of adjustable slope.  The latter signal is com-bined with the sawtooth waves to produce a second train of pulses commencing after a predetermined turn-off interval and increasing in width at a predetermined recovery rate.  Both trains of pulses are added to produce enabling signals for controlling the SCR's in the precipitator input circuit.  Arc signals produced by an arc detector cause additional downward ramping of the ramp signal to minimize electrode current during arcing.                                          .

Abstract: ABSTRACT        A knee support is provided for opposing excessive or abnormal strain or torque on the joint.  The support has a pair of pivotally interconnected rigid braces one of which snugly embraces the front of the thigh just above the patella and the other of which snugly embraces the front of the shin just below the patella.  The pivots are aligned approximately on the mean medial-lateral axis of flexion of the knee and at least the pivot on the lateral side has freedom of universal pivotal motion whilst that on the medial side has limited freedom of relative bodily displacement in the anterior-posterior direction.  Both freedoms are of sufficient magnitude to accommodate the wearer's normal degree of tibial rotation during flexion and extension.  Means are provided for locating each brace firmly  on its respective  component of the limb.

Abstract: SEALING AND ATTACHMENT ASSEMBLY    FOR MEDICAL DRAINAGE POUCH     Abstract of the Disclosure A medical drainage pouch is provided with a breathable microporous adhesive patch for attaching the pouch to the body of a patient.  The pouch includes a moisture-impermeable plastic bag having a drainage opening.  A plastic annular retainer ring    ` may be secured to the bag around the drainage opening.  The adhe-sive patch has a thin non-woven porous backing sheet which is relatively easy to tear, and the patch is attached to the bag by a flexible annular attaching ring.  The attaching ring may comprise a first layer of plastic and a second layer of hot melt adhesive.  The plastic layer of the attaching ring is heat-sealed to the retainer ring or to the bag around a generally circular area of attachment, and the adhesive patch is heat-sealed to the adhe-sive layer of the attaching ring around a generally circular area of attachment which extend  radially outwardly beyond the first area of attachment.  The outward extension of the attaching ring provides a flexible, shock-absorbing connection between the tear-able adhesive patch and the retainer ring or bag, and forces which are exerted on the adhesive patch, e.g., by the weight of the bag, are directed linearly with respect to the adhesive patch so that the tendency of the patch to tear is minimized.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a new and improved drive system and syringe for syringe pumps, wherein a disposable syringe cartridge having no valves is reliably and precisely mounted, monitored, and driven through repetitive fill and pump strokes.  Prior art disposable syringes are complex and expensive and prone to leakage.  Additionally, they are difficult to mount and remove.  The present invention overcomes these deficiencies by providing a syringe cartridge which has no valves, and the apparatus repetitively and sequentially opens and closes, by means of an external pair of tube pinchers, a pair of intake and output I.V. tubes communicating with the inlet and outlet nipples.  The cartridge includes a molded plastic cylinder having inlet and outlet nipples, a plastic piston and piston rod, and a rubber sealing cap defining a conical piston face, a pair of piston sealing rings and a sealing boot.          A coupling shoe, defining a yoke for receiving mounting bosses on the piston rod, is shaped to receive the mounting bosses with the longi-tudinal axis of the syringe horizontal, to enable rotation to a vertical position for the longitudinal axis, and to restrain the syringe against horizontal or vertical dislocation relative to the coupling shoe.

Abstract: ABSTRACT OF THE DISCLOSURE           Foamed articles are made by causing the cross-linking of a thermosetting resin, preferably a polyester resin, concur-rently with the production of carbon dioxide by the reaction of a carbonate with an inorganic acid.  The carbonate is mixed with the resin and the acid then folded in in a progressively accel-erated blending operation, whereupon carbon dioxide is generated to foam the resin, the carbonate, acid and setting time of the resin being selected to obtain an appropriate match between the progress of the foaming operation and the setting of the foam.          The foam may be made in a mold coated with resin impregnated glass fibers, the impregnating resin becoming cross-linked with the foam.          The impregnating resin may also be cross-linked with a resin gel coat, the glass fibers forming a tough layer between the gel coat and the foam.

Abstract: PROGRAMMABLE COMMUNICATIONS SUBSYSTEM  Abstract A micro processor controlled user programmable communications multiplexer subsystem (herein referred to by the symbol PCS) capable of transmitting and receiving data on any one or more of 32 communi-cations lines simultaneously.  Each line may be dynamically assigned to a variety of communication characteristics, such as line speeds, character lengths, synchronous, or asynchronous operation, and code structures as well as protocol selections.      The system of the invention provides the capability for the user to write his communications programs using novel operations commands that provide code structure and protocol independence as well as com-munication line independence.  Various hardware features and queuing techniques are employed in order to maintain high transmission rates.      Variable line scanning in the Teleprocessing Time Division Multi-plexer of the PCS is programmably permissible; i.e., the time base for line scanning is fixed and is a multiple of the communication line rate, although the actual line to be scanned is programmably variable.  The program ability is provided by a continuously scanned storage array which contains physical line addresses of the time division multiplexer. The scanning mechanism, while running, prioritizes the transmit buf-fer servicing of the individual lines.

Abstract: Abstract of the Disclosure An analog signal representing the measured output of a condition responsive transducer is supplied to a dual slope integrating analog-to-digital converter also receiving a regulated constant reference signal.  Using the integrator in a non-inverting mode, the A/D converter operates in a single conversion cycle by first positively integrating a value of the received analog signal below a maximum negative input voltage for a fixed time period and then negatively integrating a voltage signal corresponding to the differential between the reference voltage signal and the maximum voltage signal for a variable time period to a comparative threshold.  During integration, digital counts proportional to the variable integration period are accumulated and emitted for operating a digital device such as a digital display.       Digital linearization of the converter output can optionally be provided by use of a programmed microcomputer reading a programmable-read-only-memory (PROM) to run a variable frequency clock.  The clock is regulated to effect a first phase converter time corresponding with an even multiple of the power line frequency.     mb/sb
