Abstract: ABSTRACT                  JOINING POLYOLEFINIC MEMBERS BY FUSION     First and second members (e.g. pipes, fittings) of cross-linked polyolefinic material such as polyethylene having a melt flow index (MFI) of zero are joined using a third member of polyolefinic material such as polyethylene having a higher MFI e.g. 0.3.  The first member 10 and the third member gripped by clamps 18, 20 of a butt fusion machine are pressed against opposite faces of a heater plate which is then withdrawn and the members are pressed together by the clamps.  Only the third member is upset to form beads 24, 26.  Part of the third member is removed leaving a stub part 16.  The second member is joined to the stub's face 36 using the heater plate.  The part 16 is upset leaving a thin wafer 48.  The two interfaces 30, 50 limit the growth of cracks in the wafer to prevent their propagation through the pipe thickness under hoop stress.  The beads are preferably removed at each stage.

Title: Switched-capacitor circuit with large time constant
Inventor: NAGARAJ KRISHNASWAMY
IPC: G11C27/02
Filed: 1989-04-10
Granted: 1992-11-03
Abstract: Abstract of the Disclosure A switched capacitor circuit with a very large time constant. Numerous low frequency analog applications, modems for example, require this type of circuit. The capacitances required to obtain a sufficiently large time constant are reduced over prior art techniques by as much as 50%. The circuit isinsensitive to parasitic capacitances. The circuit comprises a switched input sampling capacitor, an operational amplifier and a first feedback capacitor connected in parallel with the amplifier. The switched sampling capacitor samples an input signal in a first clock phase. A second feedback capacitor is switched during the first phase to sample the output of the operational amplifier; and, in a second phase, it is switched in parallel with the first feedback capacitor of the amplifier.

Abstract: An improved packing device which holds an article being shipped between membranes. The membranes provide shock adsorption through their own resiliency and by allowing motion when forces in excess of the frictional limit are applied. A pair of rigid frames and having central openings covered by an attached pliable material, form spacers which are forced in intimate contact with a fragile article within its shipping container to absorb shocks, flexion and torsion of the container due to shipping and handling loads. The spacers can be a box-like structure with at least one open face covered with a flexible membrane. The contour of the other faces of the structure are shaped and dimensioned to match the internal geometry of the container. In some applications, the spacer structure is a wedge that fits in one corner of the container. Two to four such wedges are typically used to support the object. The framed membranes offer a versatile substitute for a variety of common packing inserts.

Title: Control system and method for controlling actual fuel delivered by individual fuel injectors
Inventor: KLASSEN DAVID J
IPC: F02D41/24
Filed: 1989-06-01
Granted: 1995-03-28
Abstract: A fuel injection control system coupled to a multiport fuel injected engine for adjusting the air/fuel mixture of each combustion chamber to a preselected level. A plurality of fuel command controllers provides a separate fuel command signal to each fuel injector in response to a single base fuel command.  During each correction interval of a correction time period, each of the fuel command signals is perturbed or offset in a predetermined sequence by a predetermined amount.  A measurement of the average of air/fuel ratios among the combustion chambers is taken each correction interval. Airflow inducted into the combustion chambers is also measured.  In response to these measurements, and the known fuel offsets, the actual fuel delivered by each fuel injector is calculated.  All the fuel command controllers are corrected in response to associated fuel calculations to balance the air/fuel ratios of each combustion chamber.

Granted: 2000-08-08
Abstract: The present invention is an improved process for purification of active heparinase and heparinase like enzymes from Gram negative organisms, in particular, Flavobacterium heparinum. The primary advantage of the process is the fact that it allows large scale processing and high yield of heparinase. The heparinase is released from the periplasmic space of the organism by osmotic shock treatment, first into an osmotically stabilized medium, secondly into a non-stabilized medium having a pH of approximately pH 6.0 and 8.6 with subsequent release into a second non-stabilized medium containing approximately 0.15 M sodium chloride, followed by fractionation by cation exchange chromatography, and, optionally, electropheresis or gel filtration chromatography. Two proteins having heparinase activity have been isolated, one having a molecular weight of approximatley 42,000 Daltons and the other having a molecular weight of 65,000 to 75,000 Daltons.      Also described is the construction of a library for screening for the genes encoding the proteins having heparinase activity and two assays for detecting organisms producing heparinase, either heparinum or genetically engineered organisms.

Abstract: ABSTRACT OF THE DISCLOSURE      In the treatment of solid residues containing heavy metals from combustion plants, the heavy-metal compounds dissolved after washing-out and subsequently precipitated are separated from the solvent, usually water or slightly acid aqueous solutions by cross-current diaphragm filtration.  The sludge obtained during filtration and comprising precipitated insoluble heavy-metal compounds is dewatered together with the remaining solid residues and made suitable for dumping, e.g. by using binders.  The cross-current diaphragm filter improves the washing of heavy metals out of the washing or waste water, and the method and the associated plant are simplified by the joint processing of the sludges containing solids.
