Abstract: With the multi-coordinate measuring machine (1), the reversal error determined at an end measure as a function of the travel axes X, Y and Z, the travel directions and the travel rates of a measuring head (12) through touch by means of a feeler (13) is fed to a measured value recording and a measured value evaluating unit (17). The values are compensated with touch values of a measurement object (16) in a connected computer (18). The result of the compensation is fed to a measured value display (19) and optionally to a measuring machine control (20).

Abstract: Purified air, typically at its dew point, is introduced into distillation column 10 through inlet 2. Oxygen-rich liquid is withdrawn through outlet 6 and is introduced into the top of a mixing column 20. Nitrogen-rich vapor passes from the top of the distillation column 10 to the bottom of the mixing column 20. In the mixing column, there is a downward flow of liquid that becomes progressively richer in nitrogen and an upward flow of vapor that becomes progressively richer in oxygen. Liquid nitrogen is withdrawn from the mixing column 20 through outlet 28 and is returned to the top of distillation column 10 to provide reflux therefor. In addition, a mixed stream comprising oxygen and nitrogen is withdrawn from the column 20 as product or waste. The mixing column 20 is provided with a first condenser 30 at its top and a second condenser 40 which takes a vapor stream from intermediate the outlet 28 and the top of the column 20 and returns condensed liquid to the column 20. The second condensation is effected by heat exchange with boiling liquid taken from and returned to the column 10. An argon-enriched oxygen stream is withdrawn from the column 10 and is separated in a second distillation column 50 to yield an argon product.

Abstract: A laser beam three dimensional position measurement system (10) includes a laser transmitter (12) mounted at a stationary reference position at a work site (16) and a receiver (14) mounted on a mobile machine (20) at the site. The transmitter (12) produces a laser reference plane by sweeping a laser beam about the transmitter. The receiver (14) includes a retroreflector (26) which intercepts and reflects laser energy back to the transmitter (12) when the laser beam sweeps past the retroreflector. The system also includes at the transmitter a circuit composed of a photodetector, timer, clock and counter. The photodetector senses laser energy reflected back to the transmitter (12) from the retroreflector (26). The timer modulates the laser beam produced by the transmitter in response to detection of the beam. The counter is connected to the clock and timer, and is enabled by the timer to start counting electrical pulses received from the clock when the beam is modulated. The counter is disabled to stop counting electrical pulses when the modulation is detected. The number of pulses counted by the counter is indicative of the range of the receiver (14) from the transmitter (12). The orientation of the beam relative to a fixed reference axis (X) at the time reflected laser energy is detected defines the direction of the receiver (14) relative to the transmitter (12).

Abstract: A process for the continuous polymerization of one or more alpha-olefins with a transition metal catalyst, in a reactor having a fluidized and/or mechanically stirred bed, in which a very small amount of an activity retarder, generally less than 0.1 ppm, is introduced continuously into the reactor at a flow rate which is varied with time so as to keep substantially constant either the polymerization rate or the content of transition metal in the polymer produced. Suitable activity retarders include polymerization inhibitors such as, for example, oxygen, alcohols, carbon monoxide and carbon dioxide and electron donor compounds such as amides and ethers.

Abstract: A buffer circuit particularly suited for driving the output pad (2) of an integrated circuit, includes features which limit the rate of change of current flow in the power supply and ground lines to reduce noise. The circuit features feedback responsive compensation for variations in the capacitive load on the pad. In one form, the circuit includes feedback capacitors (21,22) between the pad (2) and the control gate of output transistors (18,19) pulling the pad (2). The control gates of such pulling output driver transistors (18,19) are, under one operational condition, provided with a voltage which increases at a limited rate during current enablement. The steady-state enablement of the output driver transistor is established later by circuits (36,38;37,39) logically responsive to the voltage on the output pad (2). The output driver transistors (18,19) are subject to rapid disablement in response to a pulling of the control gate by high speed and drive capacity transistors (23,24). In a preferred arrangement the circuit includes tri-state operation capability.

Abstract: A method for rejuvenating Ni-H₂ battery cells suffering a voltage anomaly providing an improved cell output voltage and capacity. After the battery containing the cells suffering the voltage anomaly is removed from service, the battery is discharged. Discharging the battery reduces the hydrogen pressure within the cells, thereby increasing the rate of mass transport of free water back to the electrode stack of the cells. The cells are then left to stand for a period sufficient to allow any free water to diffuse back to the electrode stacks.
