Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to electrical connectors.          A problem exists in conflicting needs for standardization of connectors and for connectors having different opera-tional characteristics.  Different users have different operational requirements, and while some users need a snatch-release connection others need a more secure, push-pull connection.  The present invention provides both types of behavior (push-pull and snatch-release) from a single receptacle-part using suitable different plug-parts.  This invention provides an electrical connector comprising two parts, a first part having a circumferentially-extending, radially-resilient retaining ring captive therein and a second part having a circumferentially-extending retaining projection, the resilience of the retaining ring permitting the parts to be mated and separated by radial distortion of the ring as it passes over the said retaining projection during mating and separation.

Abstract: ABSTRACT OF THE DISCLOSURE    A transmisson line filter having two conductors with insulation therebetween.  A third conductor of a length related to the wavelength of the signal being filtered is spaced from one of the conductors but electrically coupled thereto.  Terminal connectors are located at each end of the filter to interconnect t?  filter into the regular transmission line of the system in which the filter is being used.  The filter can be formed of coaxial cable and can be a single frequency filter, a multiple frequency filter or a bandpass filter arrangement, In a filter trap arrangement, one end of the third conductor is conductively connected to the other of the main conductors. A method for making a coaxial embodiment of the filter is achieved by initially placing the main line inner conductor together with the third conductor within the dielectric and subsequently chopping out sections of the third conductor line to adjust its length to the wavelength of the signal being filtered and to provide electrical connection to the outer shield which is subsequently placed over the dielectric.  The filter provides unique application in controlling programs sent to subscribers in cable TV systems.     The aforementioned Abstract is neither intended to define the invention of the application which, of course, is measured by the Claims nor is it intended to be limiting as to the scope of the invention in any way.

Abstract: ABSTRACT OF THE DISCLOSURE          Method and apparatus for scoring one or more lines into the surface of a plastic part such as a container or container lid as the part is being formed.  A forming press includes a plurality of die members adapted for movement within, and with respect to, a plurality of draw pads.  A blank of sheet stock is placed between die members and draw pads.  The die members are then moved relative to the draw pads to draw the radially outer periphery of the blank across the draw pads to form the part.  As the part is being formed, scoring knives positioned in at least one of the draw pads and having scoring edges which extend above the draw pad surfaces are held against the surface of the part.  As the part is drawn across the surfaces of the draw pads, it is scored in a manner determined by the locations and orientations of the scoring knives in the draw pad and the manner in which the part surface is drawn across the scoring edges.

Abstract: RELEASABLE LOCK FOR BRAKES            Abstract A locking device for a reciprocating rod brake actuator movable between brake applying and brake releasing posi-tions includes a pivoted pawl movable between locking and releasing positions for releasably locking the rod in its brake applying position.  Yieldable biasing means normally biases the pawl to its locking position, and fluid pressure means is operative when pressurized for moving the locking means to its releasing position.  The rod is movable toward and away from the pawl, and is normally supported against movement away from the pawl by releasable support means.          Release of the support means frees the rod for free movement between its brake applying and releasing positions even though the pawl is in its locking position.

Abstract: Abstract of the Invention A catalyst chamber capable of converting the oxides of sulfur to hydrogen sulfide and the oxides of nitrogen to inert nitrogen and ammonia in the presence of a reducing atmosphere is inserted downstream of the boiler section of a fossil fuel burning power generator and there is added a system for extracting formed hydrogen sulfide from the fuel gas stream.     After combustion of the primary fuel, typically sulfur bearing coal in excess air, a gaseous hydrocarbon such as methane, is combined with the products of combustion to at least scavenge the oxygen present to form a boiler effluent which ranges from slightly oxidizing to reducing in nature.    Where the boiler effluent is reducing in nature, partial conversion of the oxides of sulfur and the oxides of nitrogen occur in the boiler, the balance occurring in the catalyst chamber.    Where the gas is slightly oxidizing or only slightly reducing, make up reducing gas is added to the flue gas, either from an external reducing gas generator, or by removing a portion of the flue gas from the boiler section for combination with a vaporized hydrocarbon and air in a secondary boiler to generate the reducing gas for the reactions to take place in the catalyst chamber.    The catalyst chamber is typically operated at a temperature from about 300 to about 830°F.  In addition to eliminating air pollutants, boiler efficiency is increased.

Abstract: SPECIFICATION          Abstract of the Disclosure A marine riser including a uniquely designed three element connection structure and associated connecting and releasing means for the inhibiting of fatigue failure caused by moments and axial loads resulting from relative motion between the fixed ocean bottom and a floating drilling platform or ship, such as a semisubmersible rig.  The system includes a preloaded connection including a female member and a male member coaxially aligned and held in compression by a nut placed in tension.  The connection holds riser pipe sections together.  The connection is preloaded through a tool to a degree such that when a load equal to the yield strength of the pipe section material is applied to the pipe sections joined by the connector, the compressed faces of the male and female members do not separate from each other.          The degree of preload would be sufficient to maintain the contact between the compressed faces under expected working loads of the pipe sections.  The tool operates in conjunction with lugs located on the nut and a flange or platform with mounting holes located on the male member. A lock is provided on the nut to prevent the disengagement of the male and female members after they are brought into compression by the nut.  The position of the lock relative to the nut lugs determines the sustained preload of the connection. Seals are provided between the male and female member to prevent leakage of fluid between the interior of the riser connector and the surrounding environment. The connector also includes provision for the support and connection of sections of kill and choke lines.

Abstract: ONE-PIECE DUAL DENSITY ACOUSTICAL PANEL          ABSTRACT OF THE DISCLOSURE              A one-piece dual density rigid acoustical core panel of significantly different density at each opposing surface, one of said surfaces having the required smoothness and flatness to facilitate the application of decorative coverings, while the opposite surface is textured to form a regular pattern of indentations which act to regulate the increased density adjacent to the flat surface.          The panel provides the most economical method available of achieving the required combined characteristics of acoustical ab-sorption, thermal insulation, surface flatness, thickness toler-ance, panel rigidity, tackability, flame-safety and impact resistance.  The method for producing the panel comprises pressing a molding tool into an uncured layer of fibrous material of predetermined uniform thickness and density at an elevated temperature to form and set the textured surface and the opposing smoother surface at the desired densities.          A process is also described for fusing a molded integrated frame about the perimeter of one of the above mentioned core panels, said frame being of greater thickness than the maximum thickness of the panel to create an air space behind the acoustical panel for the purpose of increasing acoustical absorption characteristics of the panel by introduction of a dead air space which in some design applications dissipates sound energy more efficiently than if there were no dead air space behind the panel.
