Neutral beamline with improved ion-energy recovery
A neutral beamline employing direct energy recovery of unneutralized residual ions is provided which enhances the energy recovery of the full energy ion component of the beam exiting the neutralizer cell, and thus improves the overall neutral beamline efficiency. The unneutralized full energy ions exiting the neutralizer are deflected from the beam path and the electrons in the cell are blocked by a magnetic field applied transverse to the beam direction in the neutralizer exit region. The ions which are generated at essentially ground potential and accelerated through the neutralizer cell by a negative acceleration voltage are collected at ground potential. A neutralizer cell exit end region is provided which allows the magnetic and electric fields acting on the exiting ions to be loosely coupled.

Compressor surge counter
A surge counter for a rotating compressor is provided which detects surging by monitoring the vibration signal from an accelerometer mounted on the shaft bearing of the compressor. The circuit detects a rapid increase in the amplitude envelope of the vibration signal, e.g., 4 dB or greater in less than one second, which is associated with a surge onset and increments a counter. The circuit is rendered nonresponsive for a period of about 5 seconds following the detection which corresponds to the duration of the surge condition. This prevents multiple registration of counts during the surge period due to rapid swings in vibration amplitude during the period.

Axle Lubricator.
Patent for a new and improved axle-lubricator. This design consists in "[t]he combination, with the tube having the threaded outer end, of the cap threaded to close said end, and the shank or stem carrying the conical plug at its lower or inner end, and screw-threaded to work through a threaded perforation of the cap, a shoulder being provided on the stem or shank at the base of the threads, operating to cause the unscrewing of the cap by the continued turning of the shank or stem" (lines 80-89).

Capacitively-Coupled Inductive Sensor
It is therefore an object of the present invention to provide a capacitively-coupled inductive shunt current sensor. To achieve the other object, and in accordance with the purpose of the present invention, as embodied and broadly described herein, the apparatus of this invention may comprise a capacitively coupled inductive shunt current sensor comprising: annular inductive channel means formed in a conductor carrying a high voltage pulsed current; an electrode capacitively coupled to said conductor on opposite sides of said annular inductive channel means; voltage dividing capacitor means connected in series with said electrode for reducing the magnitude of the detected output signal; output coupling means connected to said voltage dividing capacitor means for producing an output signal representative of said high voltage pulsed current.

Neutral beamline with improved ion-energy recovery
A neutral beamline generator with unneutralized ion energy recovery is provided which enhances the energy recovery of the full energy ion component of the beam exiting the neutralizer cell of the beamline. The unneutralized full energy ions exiting the neutralizer are deflected from the beam path and the electrons in the cell are blocked by a magnetic field applied transverse to the beamline in the cell exit region. The ions, which are generated at essentially ground potential and accelerated through the neutralizer cell by a negative acceleration voltage, are collected at ground potential. A neutralizer cell exit end region is provided which allows the magnetic and electric fields acting on the exiting ions to be closely coupled. As a result, the fractional energy ions exiting the cell with the full energy ions are reflected back into the gas cell. Thus, the fractional energy ions do not detract from the energy recovery efficiency of full energy ions exiting the cell which can reach the ground potential interior surfaces of the beamline housing.
