Abstract: CONTINUOUS PRODUCTION OF CROSS-LINKED POLYETHYLENE   Abstract of the Disclosure Cross-linked polyethylene is continuously produced by injecting dicumyl peroxide (Dicup) into the polyethylene in the mixing barrel of the extruder.  The Dicup injection nozzle extends into the flight of the screw of the extruder and the flight is interrupted, or notched, at this position.  This enables the Dicup to be injected at a position about half way between the extruder barrel wall and the core of the screw and also avoids pulsed back-pressure on the feed pump for the Dicup.  A closely controlled and constant ratio of cross-linking agent to raw polyethylene is obtained.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE:         In a lumber stacking method and apparatus a layer of lumber is conveyed to a lifting location where a pair of arms beneath the layer of lumber are tilted respectively about horizontal axes parallel to a horizontal plane in which the layer is located to engage beneath and raise the layer at the lifting location above the latter horizontal plane, with these arms then being advanded forwardly while supporting the raised layer.  The arms are advanced forwardly to become situated over that part of the stack which has already been formed, and at this latter stacking location the arms are lowered by being tilted in a reverse direction to as to situate the transported layer at the top of the stack which is being formed, the arms then being retracted back to the position beneath the lifting location while the transported layer remains at the top of the stack.  While these arms move over that part of a stack which has already been formed at the stacking location, lower edge regions of the arms are situated above the uppermost layer of that part of the stack which has already been formed by a distance sufficient to prevent engagement of the arms with any crooked pieces of lumber in the uppermost layer of that part of the stack which has already been formed.

Abstract: Abstract Disclosed is a light scattering smoke detector with a novel structure for preventing direct irradiation of a light sensing element with reflected light from the inner walls of its detection chamber.  The detector comprises a detection chamber composed of a cylindrical side wall closed by opposite end walls.  A light source and light detector are located in the chamber so that the sensing element is not irradiated directly but is irradiated by light reflected from smoke particles.  The side wall consists of plurality of similar laminae arranged circularly and shaped to form a serpentine path between adjoining laminae.  Smoke particles can freely enter the chamber via the serpentine path and light from the light source is effectively reflected out of the side wall but not to the light sensing element.

Abstract: K-2-19901M/tjk/78 ABSTRACT OF THE DISCLOSURE        In the present invention, a second expansion chamber which includes a second diffuser is provided in pneumatic connection with the prior art first expansion chamber of an ex-haust system for a two-cycle engine.  The second expansion chamber creates a second pressure drop or relative vacuum substantially adjacent the point of pneumatic connection between the first and second expansion chambers, which acts to draw-out the exhaust gases present at the rear-cone shaped portion of the first diffuser.  The second pressure drop or relative vacuum created by the second expansion chamber of the present invention thus overcomes the deficiencies caused by the pressure increase produced by the rear-cone shaped portion of the first diffuser.          Several embodiments of the present invention are disclosed.

Abstract: 76S47 FIRE AND FLAME RETARDANT COMPOSITIONS IN POWDERED FORM ABSTRACT OF THE DISCLOSURE An improved flame and fire retardant composition is obtained by reacting the appropriate ingredients in liquid form, drying the product to cake form and pulverizing to obtain a fire and heat retardant powder. This powdered form is advantageous in that it may be readily handled and may be associated or used with fire unstable materials that would be adversely affected by a liquid composition. The powdered form has a low bulk density and can thus create economies in the weight of material used to provide effective fire and heat retardant properties.

Abstract: ROTARY KILN WITH SATELLITE COOLER ABSTRACT       Independent suspension of satellite cooler tubes by means of wire cables in the region of outlet Or a rotary kiln, the regions being axially spaced from each other. Each suspension consists of a number of suspension elements, the number being determined by operational requirements, The suspension elements are preferably comprised of three prestressed wire Gables which are fixedly secured or connected to the kiln shell. The arrange-ment of the cables in a preferred embodiment, is such that two Or the cables exert pulling force on a respective cooler tube such that the resultant of the two forces is directed against the kiln axis, while at least one third wire cable anchored to a resilient connection generates the force directed against the direction of the said resultant. Due to a uniform force transfer by the wire cables onto the shell of the cooler tubes and in the absence of rigid connections, local stress concentrations caused by thermal dilatation and operational impacts Or kiln operation, which previously resulted in the danger Or arising cracks and breaks in the overall arrangement, are all avoided to a considerable degree.

Granted: 1983-11-29
Abstract: ABSTRACT OF THE DISCLOSURE:          A method for injection molding a particularly elongated tubular parison having a closed bottom and assuring consistently uniform wall thickness in the tube wall, is disclosed.  The method involves injection molding an open bottom tubular member, and thereafter forming a bottom wall integrally with the tubular member in a separate injection molding step in which a molten polymer is injected into a mold cavity defined, in part, by the bottom end of the tubular member.  During the first injection molding step, the core mold is held at the both ends by the other components of the mold assembly so that there is no possibility of eccentric misplacement of the elongated core in the mold cavity due to flexing of the core, which would cause non-uniformity in wall thickness of the molded tube.  The open bottom of the tube is closed by injecting additional polymer during the second injection molding step, wherein a portion of the mold cavity is defined by the bottom end of the previously formed tubular member, so that the injection molded bottom wall is integrated to the tube parison in accurate relative position to the tubular wall.

Abstract: ABSTRACT OF THE DISCLOSURE A sound receiving system has an array of microphone elements for producing output signals in response to incident sound, and signal processing means for processing the output signals to provide the array with pre-selected directional acceptance and rejection characteristics.  Such processing includes integrating the difference between the output signals of a pair of elements to produce an integrated signal summing the outputs of the same or different pair of elements to obtain a sum signal, and combining the integrated signal with the sum signal.  The spatial position of pairs of elements and their orientation permit closely spaced pairs of elements to exhibit a single highly directional characteristic, or two angularly related highly directional characteristics.  Thus, an array of microphone elements clustered at essentially a point location can exhibit either monaural or stereophonic characteristics, depending upon the type of signal processing applied to their outputs.  To minimize wind noise pickup, low frequency components of the integrated signal are suppressed to produce a filtered integrated signal, and high frequency components in the output signal of at least one of the elements are suppressed for producing a filtered output signal.  The two filtered signals are added together to produce a resultant signal wherein only the higher frequency information signals will be direc-tionally picked up and amplified.  For stereophonic use to which the inven-tion is particularly directed the microphone array is triangular with an apex microphone and at least one other microphone defining a first channel and the apex microphone and at least one further microphone defining a second channel.
