Granted: 1992-06-02
Abstract: THREE-POINT SUSPENSION FOR PAVERS        ABSTRACT           An improved "3-point" suspension for a paver disposes two of the suspension "points" at the front of the tractor unit and the third "point" at the rear.  Preferably the third suspen-sion "point" is achieved by suspending the rear of the tractor unit via laterally spaced hydraulic cylinders interconnected such that upward or downward movement of one rear wheel  or  track results in corresponding downward or upward movement of the other rear wheel or track.  The hydraulic suspension also allows the height of the rear of the tractor unit, and thus the height of the spreader screws relative to the ground, to be adjusted on the run by conjoint upward or downward movement of both rear wheels or tracks.

Granted: 1993-04-27
Abstract: ON-LINE RHEOLOGICAL MEASUREMENTS                  Abstract of the Disclosure On-line rheological measurements are made utilizing a rheometer of the type in which a first metering pump delivers diverted melt from a process main stream to a capillary passage and a second metering pump returns the diverted melt from the capillary passage to the process main stream and the viscosity of the diverted melt is measured by controlling the rate of flow of the melt to maintain constant the pressure drop between spaced apart locations along the capillary passage and measuring the temperature  of  the melt  in the capillary passage.  The measurements may be made while controlling the speed of the second metering pump independent of the speed of the first metering pump to maintain the pressure at the exit of the capillary passage essentially constant.  The capillary passage is placed in close proximity to the process main stream for maintaining a relatively short residence time during which the diverted melt resides outside the process main stream so as to attain a relatively quick response to changes in the measured viscosity.   The rheometer includes a relatively thin plate interposed between first and second blocks, the plate including a slot establishing a chamber between the first and second blocks for providing the capillary passage.

Granted: 1993-08-24
Abstract: ABSTRACT OF THE DISCLOSURE   A system for use in a floating point computation unit for providing a sign/magniture subtraction operation, which system uses propagate/generate logic responsive to the subtraction operands to produce intermediate and final propagate and generate outputs.  First carry computation logic is responsive to the final propagate and generate outputs and to a carry-in bit to produce final carry outputs and a carry-out bit.  The latter outputs are used to produce a first subtraction result.          Second carry computation logic responds to the intermediate propagate and generate outputs to produce second final carry outputs.  The latter outputs and selected intermediate propagate outputs are used to produce a second subtraction result.  The carry-out bit then selects one of the two subtraction results as the final subtraction result.   The floating point unit further normalizes an exponent result in conjunction with a mantissa result which is formed as a plurality of data slices.  The number of leading zeros in each data slice is determined and each number of leading zeros is subtracted from the exponent result to produce a plurality of subtracted results.  One of the subtracted results is then selected as the normalized exponent result.

IPC: B27K3/52
Filed: 1989-09-27
Granted: 1995-03-07
Abstract: A wood preservative composition comprises a wood preservative such as a chromated copper arsenate-oil emulsion or an ammoniacal copper arsenate emulsion having about 0.1 to 15 percent chromated copper arsenate, ammoniacal copper arsenate, or ammoniacal copper zinc arsenate, about 1 to 20 percent oil and about 0.3 to 2.5 percent (all by weight based on total final emulsion) surfactant material.  The first surfactant preferably has a hydrophilic lipophilic balance of about 7 to 9.5 and a second surfactant has a hydrophilic lipophilic balance of about 15 to 20.  It is preferred that the first surfactant have an ethoxyl mole ratio less than about 5 and that the second surfactant have a mole ratio greater than about 15.  The surfactant material may be composed of a first surfactant having an average mole ratio of about 1 to 5 and a second surfactant having an average mole ratio of about 20 to 100.  The composition is storage stable for extended periods and provides a number of beneficial properties for wood products.  A preferred group of surfactants for use in the present invention are ethoxylated alkylphenols or ethoxylated alkyl alcohols.  A related method includes establishing an emulsion in oil of a first surfactant having an ethoxyl mole ratio less than about 5 and establishing in water a second surfactant having a mole ratio  greater than about 15.  The solutions are admixed and about 0.1 to 15 percent chromated copper arsenate, ammoniacal copper arsenate, or ammoniacal copper zinc arsenate is introduced into the mixed emulsions.  The first and second surfactants may be emulsified in the oil which is subsequently admixed with the water, if desired.  The chromated copper arsenate, ammoniacal copper arsenate or ammoniacal copper zinc arsenate bearing mixed emulsions are then introduced into wood.  The composition and method are particularly useful with respect to wood products which will be used over prolonged periods in outdoor or other potentially hostile environments and are particularly useful for utility poles, building products, and marine applications.

Abstract: A cooled mold assembly for the continuous, high-speed casting of metallic strands, especially upcasting strands of copper alloys such as brass, has a hollow die in fluid communication with a melt typically held in a casting furnace. A coolerbody surrounds the die in a tight-fitting relationship to form a solidification front in the melt as it advances through the casting zone of the die. The die is preferably slip fit in the coolerbody. A shoulder on the die engages a lower face of the coolerbody and together with a small irregularity on the upper coolerbody wall prevents an axial movement of the die before it thermally expands against the coolerbody. An insulating member located between the die and the coolerbody and below the solidification front fixes the location of that front within a dimensionally uniform area of the die. The insulating member is preferably a ring of a material such as cast silica that has a low coefficient of thermal expansion, a low porosity, and is highly resistant to thermal shock. The insulating member also preferably creates a steep longitudinal temperature gradient at its upper end to promote a high cooling rate over a relatively short casting zone. An insulating hat substantially encloses the coolerbody allowing it to be immersed in the melt and preferably deeply immersed to a level above the casting zone. This mold assembly is preferably used in conjuction with apparatus for drawing the casting through the die in a cycled pattern of forward and reverse strokes characterized by a low frequency, long forward strokes, a high forward velocity and high forward and reverse accelerations.

Abstract: With this start-up control apparatus it is intended to reduce the starting jerk at elevators resulting from superimposing the motor cut-on moment and load moment and to improve the starting comfort of the elevator passengers. The brake magnet of the electromechanical holding brake of the elevator is connected for this purpose with a regulation device, by means of which there can be linearly decreasingly controlled the braking force during the elevator's start-up, so that there can be obtained a linearly ascending start-up moment of the drive. The linear decrease of the braking force first appears following decay of the cut-on moment peak of the drive motor. This can be obtained by optimum correlation of the start-up time point of a reference value transmitter of the regulation device and the drive motor as well as the proportional part (P-part) of the reference value transmitter, whose transfer function approximately corresponds to the time behavior of a PI-regulator. The cut-on moment peak can only have an inappreciable effect, since the brake spring is dimensioned such that the mechanical brake moment amounts to 3-fold to 3.5-fold of the motor rated moment or torque.
