Abstract: A multi-station machine for necking-in the open end of a metal container body includes a plurality of necking spindle assemblies mounted at circumferentially spaced locations on a tooling disc turret in coaxial alignment with corresponding base pad spindle assemblies mounted to a base pad turret.

Abstract: When drawing wire, and particularly wire of highly tenacious material which s difficult to deform, such as tungsten or molybdenum, through a die (4), lubricant is applied to the surface of the wire (1) by generating a curtain or sheet of lubricant (6, 16) emitted from a slit-like nozzle (14), and passing the wire essentially transversely through said curtain or sheet of liquid lubricant.

Abstract: A process is provided for rapidly and non-destructively evaluating the particle retention characteristics of porous membranes using a novel liquid-porosimetric technique. A ratio of two membrane permeabilities is measured at preselected operating conditions using a pair of mutually immiscible fluids, one of which is employed as a membrane wetting agent and the other used as an intrusion fluid. The first operating condition, a particular transmembrane pressure, is chosen so as to selectively intrude those pores accessible to a given sized particle, such as a virus. The second operating condition, either a second preselected transmembrane pressure or a water permeability measurement, is chosen such that nearly all of the membrane pores are intruded. The ratio of the two permeabilities obtained with each set of operating conditions is thus the percentage of total flow through the membrane pores accessible to a given sized particle.

Abstract: An improved technique more accurately determines pore pressure of sedimentary rock penetrated by a borehole from the earth's surface. Formation overburden is directly measured at one or more locations in the borehole, and a log of formation overburden is generated using the measured overburden pressures and conventional geophysical data. A linear relationship has been determined between the logarithm of effective stress for a specific mineral and the logarithm of solidity, which allows the maximum effective stress and the compaction exponent for that mineral to be determined. This linear relationship enables the effective stress and compaction exponent for rock comprising a combination of minerals to be precisely determined at multiple borehole intervals. The effective stress and overburden calculated according to the techniques to the present invention are particularly useful to geologist and well planners in the oil and gas industry.

Abstract: An apparatus and technique for fluid level determination in automatic transmissions. The invention employs an electronic control unit in association with an automatic transmission for a vehicle, the electronic control unit receiving data corresponding to transmission oil level, transmission oil temperature, engine speed, transmission speed, and transmission selected range. Upon determining that such data satisfies certain diagnostic tests, the level of transmission fluid within the transmission is determined and adjusted or otherwise normalized to ideal test conditions. The electronic control unit compensates an oil level signal for deviations in oil temperature from an optimum test temperature, and makes further compensation for deviations in engine speed and settling time at the time that the test data is acquired. Additionally, variations in oil density as a function of oil temperature are also compensated.

Abstract: The engine balancing system preferably has two pivoting counterbalance weights connected to eccentric journals on the crankshaft via their respective link arms. The use of the two pivoting weights and the particular geometrical relationships between the balancing system components enable the balancing system to substantially mimic and oppose the non-sinusoidal piston forces.

An uneven road surface is detected and a transmission ratio of the transmission is controlled accordingly to substantially eliminate hunting. An engine speed is controlled so that the engine speed may not exceed a predetermined rotational speed when the transmission gear ratio is fixed.

Abstract: An upshift control in which open-loop control parameters are adaptively adjusted to improve the shift quality in a subsequent upshift to the same ratio. A multi-variable adaptive control methodology attributes detected torque phase timing deviations to variability in the on-coming fill time and/or return spring pressure, and suitably corrects the parameter(s) so that in the next shift of the same type, the detected deviation will be reduced or eliminated. The torque phase timing deviations are detected by measuring specified intervals in relation to the achievement of predetermined input and output acceleration conditions, and comparing the measured intervals with reference intervals. The gradients of the deviations in relation to the respective control parameter are determined and stored in a look-up table, and subsequently used to determine adaptive correction values.
