Abstract: METHODS AND APPARATUS FOR PRODUCING         REFRIGERATION      ABSTRACT OF THE DISCLOSURE Refrigeration is produced by passing liquid carbon dioxide through a narrow slot into an enclosure or conduit having an inlet and an outlet in communication with ambient atmosphere.  Liquid carbon dioxide is converted to solid and gaseous phases upon passage through the slot to produce a refrigeration effect and such phases are directed toward the enclosure exit thereby entraining ambient atmosphere in the solid and gaseous stream.  This entrainment and mixing is effective to cause a relatively rapid sublimation of the solid carbon dioxide after exiting the enclosure and thus permits uniform refrigeration of a chamber into which the solid and gaseous carbon dioxide is discharged.

Abstract: Abstract of the Disclosure An insulated internal connection arrangement between a terminal end of a winding of a dynamoelectric machine and at least one other wire conductor is disclosed.  The connection arrangement includes an insulator having at least one elongated generally tubular receptacle with one end thereof open and the other end closed and having an internal restriction between the open and closed ends.  A connector disposed within the at least one receptacle, electrically joins winding and wire conductor ends. The connector has a flared portion which cooperates within the internal restriction to firmly capture the connector within the receptacle.  The insulator may include a plurality of receptacles formed from a single sheet of insulating material with the receptacles disposed generally coplanar and with each receptacle opening in the same direction.  The internal restriction may comprise a depression extending transverse to each of the receptacles.  The insulator may be formed by rolling a sheet of insulating material in a sinuous pattern to form a plurality of receptacles and providing a seam generally along a path in the direction of elongation of those receptacles to maintain the sheet in its sinuous configuration.  A transverse seam is formed near one end of the rolled sheet to close the receptacles at that one end, and a side wall of one or more of the receptacles is deformed, for example, by heating in a region between the closed and open ends of the receptacles to form the connector holding internal irregularity or restriction.           When the connected conductors are inserted into the receptacle open end, the connector passes beyond the internal irregularity or restriction, and the restriction cooperates with a flared trailing edge of the connector to hold the connector and its associated conductors within the receptacle.

Abstract: Abstract of the Disclosure An optical measurement system, e.g. for remote telemetering, eliminates the influences of time variations on light sources, transmission lines, photo detectors etc.  A pair of light sources generates two pulse-shaped optical signals of different wavelengths.  A portion of each of these signals is sent to a remote measuring location by an optical fiber. Here, a change in the state of the object being observed is converted into a variation in the quantity of light trans-mission, and the resulting optical signal is returned to the signal processing portion of the system also by an optical fiber.  This varied optical signal is then converted into an electric signal by a photo detector.  Other portions of the original optical signals from the light sources are converted into a second electric signal by another photo detector.  The ratio between the first and second electric signals is amplified by a logarithmic amplifier, and the amplified signal is passed through a sampling circuit and a synchronous detector to find the quantity of change of the measured object.

Abstract: ABSTRACT OF THE DISCLOSURE     A plurality of parallel wires are disposed between a corona discharge electrode and a surface to be electrostatically charged.  The surface is moved relative to the electrode and wires.  The wires are equally spaced from each other in a plane which is inclined relative to the surface in such a manner that the spacing between the wires and the surface increases in the direction of movement of the surface relative to the wires.  A high voltage for corona discharge is applied to the electrode.  A low voltage is applied to the wires to prevent the surface from being charged above a predetermined potential.  The low voltage may be applied to the wires by means of a zener diode connected between the wires and ground which prevents a potential induced in the wires from the electrode from exceeding the zener voltage of the diode.
