Abstract: ABSTRACT  .            Disclosed is an unloader assembly for a gas com-pressor having a compressor suction chamber and a compressor cylinder with a compressor piston slideable therein for effect-ing one-way gas flow through a suction valve assembly mounted in the compressor suction chamber, said suction valve assembly having a central passage therethrough.  An unloader piston is slideably movable in the central passage of the suction valve between a first position closing a plurality of ports in the suction valve each providing communication between the suction chamber and the suction valve central passage and a second position opening the ports.  A clearance bottle is mounted on the compressor and a valve controlled aperture permits communi-cation between the suction chamber and the clearance bottle until closed by a clearance bottle valve.

Abstract: ABSTRACT:              The invention relates to a coupling element for an optical system, in which the coupling element comprises a ball lens and a holder.  The ball lens preferably has a refractive index, which is dependent on the radius of a shell in the lens. The holder has a capillary duct, in which the ball lens and an end of an optical fibre are fixed opposite each other. The capillary, the ball lens and the fibre have substantially the same diameter for easy optical alignment of the lens and the end of the fibre. Using such optical coupling elements (monomode) fibres can be coupled to each other thereby permitting larger dimensional tolerances due to the use of said lenses.

Abstract: ABSTRACT                A hot water generator capable of producing a maximum rate of water temperature increase without generation of vapors including a heat exchanger in the form of an annularly shaped helical coil through which the water to be heated is pumped and which is connected to a piping system including a load and a combustor for rapidly providing increased combustion which is controlled in response to the temperature of the water at the out-let of the coil so that the heater can produce a maximum rate of water temperature rise without causing boiling and generating vapors in the coil.  The method concerns the shock testing of piping components by producing nearly theoretical maximum heat flux rate very quickly.

Abstract: DYNAMOELECTRIC MACHINE   INCLUDING GAS BAFFLES            Abstract of the Disclosure A dynamoelectric machine including a stator core mounted on keybars. The keybars are in turn supported on spring bars which are fastened to the frame of the machine. The mounting arrangement permits relative movement between the core and the frame and between the keybars and the adjacent spring bars so as to minimize transmission of vibration from the core to the frame. me core is cooled by causing gas under pressure to be forced radially inwardly through first passages in the stator core and radially outwardly through second passages in the core, these first and second passages alternating along the length of the stator. In order to prevent leakage of cooling gas between the inflowing gas stream and the outflowing gas stream which would otherwise reduce the amount of cooling gas flowing through the aforementioned stator core passages, a plurality of baffles are positioned on the spring bars in regions where such leakage might otherwise occur. Each baffle is of generally U-shape and includes two legs engaging opposite sides of the spring bar with which it is associated and an intermediate leg positioned between the stator core and the spring bar for blocking leakage of gas through the space between the stator core and the spring bar. One of the first mentioned legs is positioned between the spring bar and adjacent keybar and prevents leakage of gas through the space between the spring bar and the keybar.

Abstract: ABSTRACT OF THE DISCLOSURE     Automatic card embossing apparatus includes a rotatable embossing wheel carrying about its periphery punch and die pairs for all characters available for embossing.  Each character position of the wheel defines an address and the wheel is controlled for rotation to a desired address for embossing the character there located.  Data identifying all embossable characters is processed to derive three control numbers for each character, the first control number identifying the corre-sponding wheel address for the corresponding punch and die pair, the second number identifying the horizontal position on the card where the character is to be embossed, and the third control number identifying the line number on the card.  The data is sorted into ascending order of wheel addresses.  In operation, a card is transported to a reference position relative to the embossing wheel and the embossing wheel is rotated to the address of the first control number.  The distance to move the card based on the second and third control numbers is computed and the card is transported to each successive position for that first character to be embossed.  The embossing wheel then is rotated to the next address in accordance with the next first control number and the embossing card transport functions performed.  Following embossing the card is returned to its reference position, then to an output stacker where it is deflected into "accept" or "reject" portions as a function of error checks performed during data processing and embossing.

Abstract: Abstract of the Disclosure The present invention relates to a portable kit used for monitoring hyperfine particles in a fluid  medium. The kit includes a substrate which can be positioned in a magnetic force field having a component of relatively high intensity extending orthogonal to a flow-supporting surface of the substrate for attracting toward the surface particles which are adjacent the surface.  When a particle-containing fluid medium is flowed along an extended path of the surface it interact with the field so that the field precipitates particles onto the surface according to their size with those particles which are largest being precipitated first.  The kit includes a container holding precipitation-accelerating agent for mixing with the fluid to promote the separation of particles by the field when the fluid flows over the substrate.      The kit also includes flexible tubing for transporting the fluid and the agent to the substrate.

Abstract: ABSTRACT OF THE DISCLOSURE           A magnet is used to create a static magnetic field adjacent to the surface of a conductive material.  At least one conductor runs through the magnetic field.  When a pulse of current flows through the conductor, an elastic wave is generated in the material.  In a preferred embodiment, a row of individual permanent magnets is  used to create a periodic magnetic field.  One side of a coil is placed in the periodic magnetic field so that a sheet of current moves transverse to the magnetic field when a pulse of current flows through the coil. When the coil is oriented parallel to the row of magnets, a horizontal shear wave is generated in the material.  When the coil is oriented transverse to the row of magnets, a Lamb wave is generated in the material.

A line from one column is printed on a print line, the carrier is caused to escape, and any corresponding line from a succeeding column is printed on the same line. Printing and escapement continue until all corresponding lines from each column are printed on the same print line prior to causing a printer carrier return. During playout within a column, or from column to column, printer font requirements stored with the text are used to determine subsequent system events. If one of the columns, or a portion thereof, is to be printed in a different type style or language, the system will signal a need for a font change, stop the playout and await an indication that a font change has been made.

The coiled members comprise a series of equi-lead, axially aligned convolutions each having helical segments of unequal helix angles.          Alternate steep and shallow angles presented by the helical segments cooperate to provide required positive engagement with any one of a number of various size conductors while at the same time permitting the members to be easily positioned around the conductor. Other forms of the invention show the use of the equi-lead, multiple helix angle design concept for the coiled wire-engaging members in a deadend and an armor rod.        (Dkt. 15967)

Subsequent to a proper alignment of artificial teeth, the photocuring or hardening resin compound is hardened by exposure to light and artificial gingivae are formed by the same resin compound as above, followed by photocuring, thereby completing manufacture of the denture base.  Advantageously, the method disclosed herein facilitates markedly the manufacture of denture bases in comparison with conventional methods such as thermal poly-merization and casting.  The resulting denture bases show excellent properties.
