Patent CA-1055905-A (CA)
Inventor: HOWELL ALLEYNE C JR
IPC: B60M1/34
Filed: 1976-07-06
Granted: 1979-06-05
Abstract: ABSTRACT      A rail construction for rail-type electrification systems, comprising a conducting rail member having a cross-sectional configuration somewhat like a pair of channel shapes disposed back to back.  One channel shape is used for suspension or mounting, as well as rigidity.  The other channel shape con-tains a stainless steel insert in the form of a flat contact member which is secured in place by being pinched between opposed wall areas of flanges of the rail member, in conse-quence of the flanges being swaged or displaced beyond their elastic limit to effect a gripping of the contact member.  The inner walls of the flanges, which adjoin the elongate contact member, constitute metal guideways that assure a positive tracking of the collector shoe.  The advantage of the present construction over prior devices is that any small relative movements between the conducting rail member and the stainless steel insert, as occasioned by temperature changes for example, cannot result in loosening of the insert or deterioration of the electrical conductance thereto.

Abstract: ABSTRACT OF THE DISCLOSURE          A pump and motor assembly for a dishwasher including a food particle macerating means having a cutting arm attached to a helically-wound column. The cutting arm coacts with a grid-like grading element to macerate food particles to reduce them to a size where they will be removed in fluid suspension with an initial rinse liquid in the dishwasher. The food particle macerating device is capable of riding over or slipping around unmacerable food particles, such as particles of bone, without damage to itself or to associated elements of the pump-motor assembly. The macerating device further serves to dislodge unmacerable particles from the grading element, urging them into a trap provided for their collection.

Abstract: BALE LOADER AND CARRIER            ABSTRACT OF THE DISCLOSURE      A wheel mounted main frame includes supporting structure to support, for rotation, a cylindrical bale car-rier component having three longitudinally extending seg-ments at approximately 120° from each other. Each seg-ment is arcuately curved and designed to carry a plurality of cylindrical bales lengthwise therein.  Each bale is picked up by a fork pick-up attachment at one side of the front of the frame and elevated to a loading chute or cradle.  A push-er assembly pushes the bale rearwardly into one of the seg-ments of the bale carrier that is then rotated 120°.  After a bale has been loaded in each segment, further bales are loaded by the pusher assembly by pushing back the first bales within the segment until all bales are loaded or the carrier is at capacity. To unload, one hinged side of the framework is released and the bale carrier is rotated thereby dischar-ging, by gravity, the bales in each segment as each segment reaches the unloading position.

Abstract: DIGITAL DEMODULATOR FOR PHASE SHIFT KEYED SIGNALS            Abstract A digital demodulator for differential phase shift keyed (DPSK) signals includes two pairs of 1-bit integrators for continuously taking the phase difference between successive DPSK bits. Each DPSK bit is subdivided into a plurality of bits, for example 15 bits. A weighted output signal having 4 bits is provided by each 1-bit integrator for each of the bits corresponding to a DPSK bit.  The weighted output signals from each pair of 1-bit integrators are sine weighted and multiplied.  The products are then added together for application to a comparator.  The comparator compares the sum of the addition to a predetermined reference signal and provides a demodulated digital signal having a logical state dependent on whether the sum is greater or smaller than the predetermined reference signal.
