Abstract: GAS PILOT ASSEMBLY FOR UNIVERSAL APPLICATION AND METHOD OF MAKING SAME               Abstract of the Disclosure A pilot assembly includes a base having a cylindrical side wall which holds an electrode sub-assembly and glass preforms in place for fusing the glass to secure the electrode subassembly to the base. Prior-to fusing, a spark electrode is assembled by inserting it into a metal clip receptacle held in a ceramic insulator body forming a part of the electrode subassembly.  A pilot tip and orifice subassembly are secured to the base.  Fusion of the glass and brazing of the metal including the high tension clip to bring it to spring temper for connection to a plugged wire are accomplished in a single step of heating.  The pilot tip includes a locator member which holds the spark electrode in place during fusing and establishes the spark gap.  It is removed after fusing.  A connecting flange of a bracket is then positioned relative to the side wall of the base to achieve a desired angular disposition, axial orientation and height adjustment of the base relative to the bracket; and the bracket is welded to the side wall of the base. Thus, the same structural elements can be used for many different models of a gas pilot assembly without the need for special parts or process steps for manufacture.

Abstract: ABSTRACT      A recording arrangement for processing images for manufacturing printing forms wherein modulated laser light containing the image passes through a multi-mode waveguide to a recording element and wherein the modulated laser light beam illuminates a diaphragm which is imaged on a light sensitive recording medium for the exposure. A multi-mode light waveguide has a disadvantage in that the light distribution at its exit surface is unequal because of the modes formed in the light waveguide.  Thus, the diaphragm will be unequally illuminated and the exposure plane will have non-homogeneous light distribution so that the exposure of the recording medium is uneven. In the present invention, a scattering disc (6) and an additional convergent lens (13) is placed between the exit surface (2) of the light waveguide (1) and the diaphragm (17) and the spacing are selected so as to obtain the desired result which gives homogeneous illumination of the diaphragm and accurate and even recording.

Abstract: Simulateur électronique pour la simulation analogique en temps réel de tout genre de turbine hydraulique, comprenant possiblement une conduite forcée menant à la turbine et un régulateur de vitesse. Ce simulateur comprend un circuit d'introduction de conditions de fonctionnement de la turbine simulée, représentant par exemple l'ouverture d'une vanne contrôlant le débit d'eau à l'intérieur de la turbine et la chute de l'eau amenée à la même turbine. Des circuits multiplicateurs transforment ces conditions de fonctionnement en signaux normalisés qui sont transmis à des circuits simulateurs de fonctions de transfert. Chacun de ces circuits simulateurs reçoit comme signal d'entrée au moins un des signaux normalisés et fournit un signal de sortie représentant un résultat intermédiaire, tel que le débit et la puissance générée. D'autres circuits multiplicateurs convertissent une partie des résultats intermédiaires en signaux représentatifs du fonctionnement de la turbine. L'invention permet aussi l'addition d'un circuit simulant la conduite forcée et journissant, à partir du débit, la chute d'eau ainsi qu'un circuit simulant un régulateur de vitesse modifiant l'ouverture de la vanne en fonction de la vitesse angulaire de la turbine, de la puissance générée et de valeurs de consigne.

Abstract: FIXING OF TETRA (HYDROCARBYL) BORATE                SALT IMAGING SYSTEMS                           Abstract It is highly desirable to have light sensitive imaging systems which do not use expensive silver materials in their construction, yet still have some of the properties of silver imaging systems such as their ability to be fixed.          Light sensitive systems using tetra(hydrocarbyl) borates are easily constructed and do not require expen-sive materials therein.  It has been found that the borates may be fixed by converting the tetra(hydrocarbyl) borate to a compound which does not have four carbon-to-boron bonds.

Abstract: ABSTRACT OF THE DISCLOSURE A data tone disabling circuit for disabling prior to the transmission of data on a telephone transmission line a device which is connected to the line for improving voice transmission on the line.  The disabling circuit operates in response to the transmission on the line of a tone signal whose frequency falls within a predetermined band width and which also has a pre-determined amplitude and minimum duration.  The disabling circuit processes the signal transmitted on the line to generate two control signals.  One of the control signals is a function of the transmission line signal.  The other is a function of the energy contained in the transmission line signal which lies in a pre-determined frequency band which is not the tone frequency band. When the control signal which is a function of the transmission line signal is greater in amplitude than both a reference signal and the energy related control signal, a phase locked loop is enabled to capture the tone signal and disable the voice im-proving device.

Abstract: ABSTRACT OF THE DISCLOSURE Erosion- and decomposition-caused deterioration of exterior regions of an arc-extinguishing housing included in a high-voltage switch is eliminated or reduced. The switch also includes a stationary contact within a sealed chamber defined by the housing and a switch blade movable into and out of engagement with the stationary contact through a slit communicating with the chamber. The stationary contact and the switch blade are connectable to opposite sides of a high-voltage source. The deterioration-prone region of the housing resides between one housing portion which is connected to and is at the voltage of the stationary con-tact, and another portion which is essentially electrically floating. Deterioration is eliminated or reduced by closely capacitively coupling current to the region from a conductive projection connected to the stationary contact. The projection is closely spaced from, and may be either above or below, the region.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a method and apparatus for positioning a selected liquid at the bottom of a well, such as an oil well, while having in the well at least a string of tubing, a sucker rod pump, a string of sucker rods, and a standing valve, without disturbing the rods, pump, tubing, or standing valve.  A bypass conduit or shroud surrounds the wall of the tubing at a point above the pump where there is an opening in the wall of the tubing and is carried down, outside the tubing to a point below the conventional mud anchor, into the inlet of an overpressure relief valve.  The outlet of the valve empties into the well annulus.  If the normal pressure at the bottom of the tubing due to the head of liquid in the tubing is P, the overpressure valve is set to open at a pressure of P+P1, where P1 is a selected value, such as say 100 psi.  At the surface, means are provided to close off the top of the tubing.  Means are provided to inject the selected liquid into the top of the tubing at a selected pressure P2 above atmospheric, where P2 may be say 150 psi.  This causes the pressure at the bottom of the tubing to rise to P+P2.  Since P+P2 is now greater than P+P1, the overpressure valve will open and pass as much liquid as is pumped into the tubing at the surface.  A cross-flow unit is inserted into the tubing and the shroud at the standing valve to permit the radial flow of well fluids from outside the shroud to the inlet to the standing valve, and to permit the longitudinal flow of liquid down the annulus inside the shroud, to the relief valve.
