Abstract: EDGE TERMINATION FOR AN ELECTRICAL CIRCUIT DEVICE                 Abstract of the Disclosure An electrical circuit device having a ceramic substrate including a thick or thin film circuit on at least one surface thereof and an intersecting edge surface which may support termination leads anchored thereto and further retained by solder deposited upon an edge termination coating.  The termination coating underlying the solder extends over the edge defined by the intersecting surfaces.  The component resides in form of the substrate to include an indented area in the form of a notch or a groove which intersects both adjoin-ing surfaces to provide a means of receiving edge termination material, so as to insure a continuous and non-interrupted deposit of the material to complete the electrical circuit between the leads and the respective circuit components of the circuit defined on the said one substrate surface.

Abstract: Abstract A monitoring system for measuring the phase currents of a filter circuit, the monitoring system having current measuring transformers coupled to respective filter sections for suppressing the harmonic content.  Voltage measuring transformers are provided for measuring the network phase voltages, each such voltage measuring transformer being coupled to an electronic filter simulator and a filtering section for suppressing harmonic content.  The funda-mental frequency component of the measured phase currents and the simulated phase currents are conducted to transient comparator circuitry which is coupled to indicating and triggering circuitry having individual counter stages.  Only rapid variations between the measured and simulated phase currents will result in fault indications, thereby preventing false indications resulting from varia-tions in temperature.

Abstract: TITLE            SHEET BINDING APPARATUS          ABSTRACT OF THE DISCLOSURE          An adhesive binding apparatus is disclosed for edge binding multiple sets of sheet material held in a stack of multiple trays.  The binding apparatus includes an adhesive transfer belt 22 fabricated from a non-metallic synthetic fiber movable between a retracted position out of contact with the edges of the multiple sets of sheet material and an adhesive application posi-tion for transfer of the adhesive on the belt onto edges of the sets of sheet material.  The endless belt extends through an adhesive dispenser 24 mounted to a transfer frame 26.  A belt aligning assembly 34 aligns the belt relative to the aligned edges of the multiple sets of sheet material for transfer of the adhesive thereto. The alignment assembly centers the frontside of the belt coated with adhesive so that it is parallel to a plane extending along the edges of the multiple sets of sheet material.  The alignment assembly includes a belt align-ing bar 38 and adjustable belt aligning stops 42.  An ad-hesive metering assembly 54 is also provided for metering a continous strip of adhesive from the adhesive dispenser onto the transfer belt of narrower width than the width of the belt so that the adhesive does not migrate to the backside of the belt.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved apparatus and method for manufacturing completed foam plastic containers are provided herein.  An endless mandrel chain carries cup forming mandrels along a manufacturing path.  After each mandrel is preheated, a bottom blank is placed on the mandrel bottom and held there by a vacuum.  A cylindrical blank formed from longitudinally stretch-oriented foam sheet material is then placed onto the mandrel. This cylindrical blank is tightly tamped onto the mandrel and is clamped in place.  Radiant heat is then used to shrink form a finished container.          The bottom is then sealed to the cylindrical blank and the mandrel is transferred to a curling assembly where the top edge portion of each finished container is lubricated and then curled to form a finished rim.          Such apparatus may form containers having a dual tapered configuration which allows the containers to be more tightly stacked.

Abstract: ABSTRACT An improved sprinkler (20) of the type adapted to rotate and create a predefined horizontal spray pattern around it. A rotating turbine (34) drives a cylindrical nozzle (44) assembly having a plurality of nozzle openings (52) therein. The nozzle openings deliver streams of water of variable length and volume. A pattern defining disk (40) is used to continuously and proportionately expose the nozzle openings (52) to the source of pressurized water according to a preset function of the instantaneous rotational position of the nozzle opening (52) as the cylindrical member (44) turns to create the spray pattern. The nozzle openings (52) supply a relatively constant volume of water to all portions of the pattern.

Abstract: Abstract:     A semiconductor laser device has at least a first semiconductor layer, second and third semiconductor layers formed to sandwich the first semiconductor layer and having a wider band gap and a lower refractive index than those of the first semiconductor layer, an optical resonator and carrier injection means.  The device is characterized in that at least the first semiconductor layer has an angle of inclination (.theta.) relative to an axis perpendicular to optically flat faces constituting the optical resonator. The inclination angle .theta. (rad) should preferably lie in the range of:                             where .theta.z denotes a reflection angle, .theta.c a critical angle, W is 1/2 the thickness of the waveguide, and ? is the cavity length.  The device is effective for preventing the laser facets from breaking down, and as a result can produce more power than prior lasers.

Abstract: Otis 4-131 WELL TOOL            Abstract of the Disclosure A landing nipple having a port through the wall thereof which is controlled by a valve carried by a non-circular ring which ring may be moved toward circular position by introduc-tion of a sleeve-like member into the bore through the ring to unseat the valve.   This invention relates to landing nipples.    Landing nipples are frequently provided with a port for permitting flow between the interior and the exterior of the nipple.  In many instances it is desirable to be able to control flow through this port.  In producing petroleum wells, ported nipples have been used in the past with the port controlled by valves using elastomeric material to provide seals.  For instance, a sleeve may be shifted to open and close a port with elastomeric material between the sleeve and the nipple body.    Landing nipples may be subjected to conditions in which elastomeric material is not suitable.  In landing nipples for wells producing fluid of high acidic content the fluid attacks the elastomeric material and in time renders ineffective the ability of the elastomeric material to control flow through a port.    It is an object of this invention to provide a landing nipple with a valved port controlling flow through the side wall  of  the nipple without using seals of elastomeric material.    Another object is to provide a landing nipple having a valve controlled port for flow through the wall of the nipple in which all parts of the nipple are made of metallic material.
