Abstract: A hydroentangled composite fabric is made by subjecting a spunbonded base web material of continuous man-made filaments to stretching in the cross direction at least 5 percent of its original dimension but less than the cross direction elongation of the material under ambient temperature conditions at the time of stretching. The base web material in its cross-stretched condition is stabilized to provide a prestretched base web material substantially free from cross direction tensioning. A covering layer of fluid dispersible fibers, preferably in the form of one or more wet-laid wood pulp fibrous webs, is applied to one surface of the relaxed prestretched base web to form a multilayer structure and the multilayer structure is subjected to hydroentanglement while in its relaxed condition to embed the covering fibers in the spunbonded base layer and affix the fiber layer to one surface of the prestretched base material. The resultant fabric exhibits improved dimensional stability and cross-directional strength characteristics closely approaching those in the machine direction.

Abstract: An assay for activated factor VII (factor VIIa) has been developed using truncated tissue factor (TF), a soluble mutant form of TF that retains the cofactor function of TF toward factor VIIa Unlike full-length TF, however, tTF appears not to sup-port the conversion of factor VII to VIIa. As a result, the tTF assay for factor VIIa is free from interference from factor VII in the plasma and is therefore specific for factor VIIa. The assay is much simpler than existing assays, because it is a single-stage clot. ting assay performed almost identically to a PT assay. It is also considerably more sensitive than current assays for factor VIIa in plasma. Since he tTF assay is calibrated against a factor VIIa standard, it yields an absolute concentration of factor VIIa in ng/ ml.

Granted: 2003-08-19
Abstract: Apparatus, and a corresponding method for its operation, for controlling the air/fuel ratio in a large engine having one or more banks of cylinders with separate intake and exhaust manifolds. Oxygen sensors in the manifolds are sampled periodically to provide the apparatus with an indication of the level of oxygen, and therefore an indication of the level of various pollutants, in exhaust gases dis-charged from the engine. The apparatus, preferably in microprocessor form, computes a fuel control correction based on the difference between the sensed oxygen level and a desired oxygen level in each exhaust manifold. The correction is applied in the form of a change to the pulse width of a binary control signal applied to a solenoid valve. In the illustrative embodiment, the solenoid valve is coupled to a fuel pressure regulator and functions to vent an air chamber in the regulator when the solenoid is actuated. Changing the pulse width of the control signal varies the average fuel pressure and thereby controls the air/fuel ratio, which in turn corrects the oxygen level in the exhaust manifold. The controller also monitors various temperatures in the engine and selectively disables control of the air/fuel ratio when selected temperatures fall outside assigned limits.

Title: Air conditioning control system
Inventor: HARVEY WILLIAM JOSEPH
IPC: G05D23/19
Filed: 1995-01-11
Granted: 1999-01-12
Abstract: An air conditioning control system monitors the temperature in the vicinity of electronic equipment using one or more sensors placed either in the equipment area or at the outlet of an air conditioning duct or vent. The temperature sensors supply signals to a microprocessor that is programmed to adjust the output of a system controller such that the amount of cooling provided by the air conditioning system is controlled. Illustratively, when the air conditioning system is restarted after a power failure, the power applied to one or more air conditioning fan motors is controlled, such as by throttling the motors down to an acceptable speed, to in turn control the cooling effect on the equipment. The amount of cool air produced by the air conditioning system is detected by the sensors, thereby forming a feedback control loop. Using this arrangement, electronic equipment failures which occur because of thermal shock due to air conditioning start ups after cooling system outages are reduced, by lowering the rate of temperature change to which electronic equipment is exposed.

Abstract: An error suppressing circuit (301) and method therefor for a phase locked loop (PLL) (300). According to one embodiment of the present invention, a transient condition, for example, a bandwidth switch, in the PLL (300) is detected. The PLL (300) is opened for a period of time (509) responsive to detecting the transient condition. The phase of a reference frequency signal (115) and the phase of an output frequency signal (116 or 117) are synchronized after a lapse of the period of time (509). The PLL (300) is closed responsive to the phase of the reference frequency signal (115) and the phase of the output frequency signal (116 or 117) being synchronized. The present invention advantageously reduces the length of time it takes for the PLL (300) to correct for the phase and frequency error generated by the transient condition, and is capable of operating with various types of PLLs.

Abstract: Sheet steel pan forms bent or rollformed to specific "universal" profiles allow the manufacture of concrete tread filled steel stairs or precast concrete stairs.  The profiles adjust against each other under the specific angle of 26.565° and thereby, used in series, create stairways of various rise and run relations, maintaing the same profile at all times, satisfying requirements of all building codes and follow the measure of the human step on an incline. These "universal" profiles are designed to standardize stair construction, save labor and material and produce stairs more economically than conventional methods employed in today's construction industry.
