Abstract: MULTIPLE DRIVER LOUDSPEAKER SYSTEM                 ABSTRACT OF THE DISCLOSURE       A multiple driver loudspeaker system comprises two angularly spaced rear rectangular baffles each nearly filled with four closely spaced full-range small loudspeakers with a port tube passing through the center of each rear baffle and the junction therebetween.  A front baffle carries a small centrally located loudspeaker.  The front loudspeaker is backed by a cavity that is vented through the port tube at the intersection between the rear baffles.  Each of the remaining loudspeakers is backed by a cavity with the four cavities associated with each rear baffle being vented through the associated port tube through channels located at the front of each cavity.  Two bullets are cantilevered from the front baffle rearward and essentially concentric within the respective centrally located ports.  The volume of each of the nine cavities is substantially the same. The nine loudspeakers are connected in phase and in series and energized through an active equalizer having a sharp low-frequency cutoff that prevents the loudspeakers from being energized with appreciable energy much below the port tube and cavity resonance of each ported enclosure, typically 40 Hz while coacting with the loudspeakers to provide substantially uniform acoustic power radiation over substantially the full audio frequency range. In an alternative embodiment of the invention there is a common cavity behind eight drivers, and a pair of port tubes include damping material inside to lower the Q of the resonant elements comprising the cavity and port tubes.

Abstract: ABSTRACT         A dual discharge hopper device for the cargo body of a bulk cargo carrying wheeled vehicle has at least one transverse side wall which is pivoted and releasably latched for free dis-charge of material from the cargo body, and also has a bottom closure which provides for controlled discharge of material.  A diverter panel is mounted on a shaft at the bottom of the device alongside the pivoted side wall, and is movable between a con-trolled discharge position in which it confronts the pivoted side-wall, and a free discharge position in which it lies diagonally across the device to block the controlled discharge closure.  Two opposite sidewalls may be pivoted, in which case there are two diverter panels the upper ends of which effectively meet to block the controlled discharge closure.

Abstract: A MACHINE FOR SPIRALLY WRAPPING A CONTINUOUS ELEMENT    AROUND AN ANNULAR TIRE BEAD                 Abstract of the Disclosure A machine for spirally wrapping a continuous element, such as a cord or tape, around an annular tire bead.  The machine is provided with a mechanism for holding a tire bead and rotating it in a fixed plane and at a predetermined speed, while a device with the element rotates about the rotating bead to wrap a portion of the continuous element around the bead at a speed which is correlated to the rotational speed of the tire bead so that the finished tire bead has a predetermined spiral wrap which can be varied by changing the relative rotational speeds of the tire bead and element about the tire bead.  The machine is supplied with a braking mechanism which is designed to cushion the stop of the bead wrapping mechanism, rather than bringing it to an abrupt halt and to bring the bead wrapping mechanism always to a halt at a desired position for beginning the wrapping of another bead.  A knife is furnished for cutting the continuous element after the bead wrapping operation is completed and the machine is stopped. One of the cut ends of the continuous element is held adjacent the knife, thereby eliminating the need for an operator to reach into the machine to remove the loose end for wrapping around a newly positioned bead in the machine.

Granted: 1981-08-18
Abstract: ABSTRACT OF THE DISCLOSURE       Optical scanning apparatus including a rotating pyramidal mirror scanning wheel with reflector segments for deflecting a laser beam into and away from a doublet mirror roof reflector associated with said scanning wheel.  The scanning wheel introduces components of vertical and horizontal angular deviation into the beam, the vertical deviation component being cancelled by inversion through the roof reflector while the horizontal angular component is doubled upon the second reflection from the scanning wheel so that the output beam is vertically wobble-free and stable while the beam is scanned through the sum of the horizontal angular components intro-duced by the wheel.  The scanner is employed to create a flying spot scan from a laser beam in photosensitive plate exposure apparatus, one form of which employs superimposed laser read and expose (write) beams of different frequencies which are simultaneously scanned without chromatic aberration, and subsequently separated to read copy and to expose a photosensitive plate surface as in the production of printing plates.

Abstract: A B S T R A C T     The closure consists of inner and outer caps which are disposed concentrically about the mouth of a container.          A flap or latch is cut into the side wall of the inner cap and the latch is biased such that its upper edge is norm-ally disposed beneath a lip formed in the brim of the con-tainer to lock the inner cap about the mouth of the contain-er.  The outer cap is maintained concentrically about the inner cap by means of the lower edge of the latch which is accommodated in an annular groove formed in the inside wall of the outer cap.  The caps may be removed from the container by first forcing the outer cap downwardly relative to the inner cap.  As the outer cap moves downwardly the wall of its groove contacts the lower portion of the latch and causes the latch to pivot to a position at which its upper edge is no longer beneath the brim lip.  Secondly the inner cap is grasped along with the outer cap and the two caps are removed together as a unit from the container.
