Title: A symmetrically balanced phase and amplitude base band processor for a quadrature receiver
Inventor: FUNDERBURK DION M
IPC: H04L27/00
Filed: 1993-02-24
Abstract: A SYMMETRICALLY BALANCED PHASE AND AMPLITUDE BASE BAND PROCESSOR         FOR A QUADRATURE RECEIVER                     Abstract of the Disclosure A digital receiver (10) has a symmetrical base band processor (28, 30, 32, 34, and 36) which concurrently provides a left and a right channel of audio information. Because of the symmetrical design of the base band processor, each of the left and right channels of information has perfectly balanced phase and amplitude with respect to each other. The base band processor includes an adaptive gain compensator (28), multipliers (30, 32), and high pass filters (34, 36). Compensator (28) iteratively derives a gain factor which is multiplied by both an in-phase component and a quadrature component of a quadrature modulated input signal to respectively provide a composite of the left and right channels and a difference between the left and right channels. Subsequently, adders (44, 48) arithmetically manipulate the composite and difference of the channels to separate the left and the right audio information.

Inventor: MORSE RONALD W
IPC: H01R13/52
Filed: 1993-03-08
Abstract: ABSTRACT OF THE DISCLOSURE An electrical connector is made repairable by providing a front insert which is removable from and retained in the shell by an O-ring. The shell includes an undercut in which the O-ring is mounted, and the insert includes a circumferential elliptical groove. In use, as the insert assembly is inserted into the shell, the O-ring mounted on the undercut of the shell is compressed by the insert until it reaches the groove, whereupon it expands into the groove in a direction parallel to the direction of insertion, which constitutes the major axis of the elliptical profile of the groove, and thus provides positive retention and sealing without the need for additional retention mechanisms. Removal is facilitated by a removal tool which includes hooks extending from a front circumference of a sleeve of the removal tool. The hooks are inserted through slots in the insert and past a collar provided around the mating interface of the insert. The tool is then rotated a short distance to cause the hooks to engage a back surface of the collar, while a piston provides a biasing force to lock the insert against the connector during removal.

Abstract: IMPROVED METHOD AND APPARATUS FOR DISPENSING RINSE WATER        ADDITIVE IN AN AUTOMATIC WASHING MACHINE                    RICHARD M. BAGINSKI JEROME P. CAPPEL GARY E. McKIBBEN               ABSTRACT OF THE DISCLOSURE An improved method and apparatus for accurately measuring and  dispensing  a  rinse  water  additive  in  an  automatic  washing machine.   In  a  particularly  preferred  embodiment,  a  method  is provided for accurately measuring a relatively small volume of fluid product by forming  an  annular  column within the  dispenser.   The annular column extends at least to approximately the desired fill level for the additive so that the relatively small amount of fluid product causes a substantial change in the fluid's vertical position within the dispenser.  This is preferably accomplished by providing a dispenser having an internal pushup in its base, the pushup extending at  least  to  approximately  the  desired  fill  level  within  the dispenser.  An improved sealing means is also provided for the valve used to close the filling and dispensing aperture in dispenser body during the wash cycle.  Flexible securement means are used to secure a recessed valve means to the dispenser to minimize the chances of premature opening during the wash cycle.  Each of these improvements helps to insure that the correct amount of additive will be added to the dispenser and that substantially all of additive initially added to the dispenser will  be present when the valve is opened by the centrifugal force of the spin cycle so that all of the material can be effectively utilized during the rinse cycle.

Abstract: A splice for regenerated cellulose tubular food casing. The splice includes a splicing tape comprising a regenerated cellulose film coated on at least one surface with a polyvinylidene chloride polymer (saran) and having a film thickness of 0.002 to 0.01 inches. The splicing tape is perforated to remove from ten to thirty percent of the area of the film. The removal of material from the splicing tape provides an elongation at break of at least twenty percent at a tensile force of between 500 and 1250 psi in a direction transverse to the direction of the longitudinal axis of the casing. The break force in that direction should be at least 100 psi greater than the force required to obtain the desired elongation. To form the splice, the splicing tape is wrapped around and sealed at the coated surface to a leading end of a first regenerated cellulose tubular food casing and a trailing end of a second regenerated cellulose tubular food casing wherein the ends are proximate each other.
