Abstract: S P E C I F I C A T I O N            PRESSURIZED GAS DISCHARGING APPARATUS FOR USE AS A DOWN-BORE SEISMIC IMPULSE SOURCE     Inventor:  STEPHEN V. CHELMINSKI                   ABSTRACT OF THE DISCLOSURE      Improved pressurized gas discharging apparatus for use as a down-bore seismic impulse source provides a compact, efficient axially stacked assembly of components within a one piece elongated tubular shell housing-having removable end closures.  Within the tubular housing, removable partition means define a charge chamber and an operating chamber having an operating shuttle release means therebetween for sudden release of high pressure gas present in the charge chamber through a discharge port into the surrounding environment.          Gas flow passageways for the supply of high pressure gas to the chambers extend longitudinally within the wall of the tubular housing and communicate with passages in the parti-tion means.  The shuttle release means may be actuated by a solenoid valve also removably positioned within the tubular housing for controlling gas flow through passageways also located within the wall of the tubular housing and within the partition means.  The components are all advantageously re-movably positioned within the tubular shell without rigid attachment to one another thus permitting convenient disassem-bly for replacement to change the device's operating parame-ters or for repair.  The housing is elongated and narrow enabling with no external protrusions to interfere with in-sertion for convenient use within a narrow borehole as a down-bore seismic impulse source.  The housing forward end closure may be cone shaped to facilitate such insertion while the rear end closure includes means for connection to a source of pressurized gas and an electrical cable to power the solenoid valve.

Abstract: An optical device for gating an incident light ray which utilizes the principle of absorption edge shift in a semiconductor due to an external electric field.  The optical device comprises a semiconductor material and a source of bias potential applied thereacross.  In a preferred embodiment, a PN junction is provided for control purposes such that the potential is primarily dropped across the junction.  The absorption band edge of the semiconductor is selected to correspond to the wavelength of the incident radiation to be controlled whereby in the normal mode of operation, the semiconductor appears to be transparent to the incident radiation.  When charged carriers are introduced at the junction, the potential is dropped across the semiconductor, causing an absorption edge shift towards longer wavelengths.  In this mode of operation, the incident radiation is substantially absorbed, or attenuated, by the semiconductor.

Abstract: ABSTRACT             A thread feeder for use in textile machines, of the type including a rotary drum on which a thread issuing from a thread bobbin is wound tangentially to form a thread reservoir. The thread is removed from the drum in tangential direction over a removal edge and passes through a stationary guide element disposed at a radially spaced location relatively to the drum, generally at the level of the removal edge.  The device further includes a thread control element movable transversely to the thread and located generally at the level of the removal edge of the drum when the thread is being unwound.  According to the invention, the thread control element is located in the path of the thread between the drum and the stationary guide element and is arranged to move below the level of the removal edge when not subjected to thread tension, the movement of the control element being caused by its own weight or by a spring.  Accordingly, when the thread becomes loose between the textile machine and the feeder, the drum winds back the already unwound thread in the wrong direction onto the removal edge region of the drum for temporary storage of the thread.

Abstract: Abstract of the Disclosure A method of cationic electrodeposition on an electrodconductive substrate is disclosed.  The method of the invention employs as the electrocoating vehicle an aqueous dispersion of a quaternary ammonium carbonate-containing resin.  Electrodeposition of the resin is accomplished without generating harmful acid from the counter ion.  The carbonate counter ion is continuously evolved from the electrodeposition bath at the anode as carbon dioxide.           The quaternary ammonium carbonate-containing polymers are also useful as feed resins for controlling the pH of aqueous dispersions of acidified cationic resins used in electrodeposition.  Upon electrodeposition, these resins generate acid which can build up to undesirable levels in the electrodeposition bath.  The quaternary ammonium carbonate-containing polymers are relatively basic and when fed into the bath react with the acid to form the corresponding quaternary ammonium slat of the acid releasing carbon dioxide.  This controls the pH of the bath and provides additional cationic resin for electrodeposition.           Utilizing the polymeric quaternary ammonium carbonates in this manner minimizes the need for controlling acid build-up in the electro-deposition bath by conventional techniques such as by treating the bath with ultrafiltration or electrodialysis.

A small castoring wheel assembly supports the rear end of the auger assembly.  When the small wheel is lowered into contact with the ground, the wheel may be rotated slowly by the electric motor thus enabling the auger assembly to be moved as desired.  Directional control is by steering the rear end of the auger assembly manually, adjacent to where the switch is located to connect and disconnect the battery to the motor.
