Abstract: Abstract of the Disclosure Method for Displaying Load Distribution by Monitoring a Work Vehicle Suspension In the field of off-highway trucks, overloading and disproportionate load placement lead to undesirable vehicle stresses.  The present invention pertains to an apparatus for displaying the distribution of the load, in an off-highway truck, to both the truck operator and the loader operator.  The information is conveyed to the operators using displays having varying color ranges generally indicative of the load in portions of the dump body of the truck.  Using this tool the truck operator attains optimum positioning of the truck prior to and during the loading cycle, while the loader operator directs loads to portions of the dump body having lower displayed loads.

Title: Additive for promoting slag formation in steel refining ladle
Inventor: BOWMAN BRADFORD C
IPC: C21C7/076
Filed: 1989-01-13
Granted: 1993-08-10
Abstract: ABSTRACT        In ladle refining of steel a molten protective slag covering is used consisting of iron blast furnace slag, or of a mixture of solid burnt lime and/or burnt dolomitic lime together with iron blast furnace slag in an amount effective to serve as a flux promoting the melting of the lime and dolomitic lime.  The iron blast furnace slag avoids the environmentally harmful emissions caused by use of fluorspar as a flux.  It forms a quicker melting slag, resulting in lower power usage and shorter refining times.  It forms a final slag with good physical properties.  There is consi-derable reduction of wear of the ladle and roof refractories and carbon pick up from the ladle refining electrodes is minimized.

Title: Sample/hold amplifier for integrated circuits
Inventor: MILLER GERALD A
IPC: G11C27/02
Filed: 1989-01-30
Granted: 1991-07-30
Abstract: 935.132 ABSTRACT OF THE DISCLOSURE           A sample/hold amplifier comprising two trans-conductance stages with their inverting input terminals connected together.  In sample mode, the input signal is connected to the non-inverting input of the first stage, and a hold capacitor is connected to the non-inverting input terminal of the second stage and driven by the amplifier output through a feedback circuit which forces the hold capacitor voltage to track the input signal.          Upon switchover to hold mode, the roles of the two trans-conductance stages are interchanged:  The non-inverting input terminal of the first stage is connected through a feedback circuit to the amplifier output, and the second stage receives as an input signal the voltage of the hold capacitor, which now is disconnected from the amplifier output.  The net offset voltage developed on the hold capacitor is the difference between the respective offsets of the two transconductance stages.  This net offset volt-age is compensated for by an equal and opposite voltage in hold mode, due to the interchange of roles of the two transconductance stages.

Abstract: DYNAMIC BURST CONTROL FOR DATA TRANSFERS         ABSTRACT OF THE DISCLOSURE         In a data processing system, a device con-troller, configured to control data transfers between a processor unit and a peripheral device on an input/out-put bus, is provided with apparatus that permits a data transfer cycle to continue until all data has been transferred, or to allow for interruption of the data transfer cycle by another device controller requesting access to the input/output via a request signal.  Dur-ing a data transfer cycle the apparatus responds to detection of the request signal to interrupt the data transfer cycle after a predetermined number of data words are transferred, permitting access to the input/ output bus for other of the device controllers.  In absence of the request signal, the apparatus permits the data transfer to continue until all data has been transferred between the peripheral device and the pro-cessor unit.
