Patent CA-2163473-A1 (CA)
Inventor: AGAZZI OSCAR ERNESTO
IPC: G11B5/09
Filed: 1995-11-22
Abstract: A method and apparatus for the processing of magnetic recording data signals which provides for the cancellation of the effects of precursor intersymbol interference (ISI) in the data signals. According to one illustrative embodiment, an adaptive filter is used to produce a replica of the precursor ISI, which is then subtracted from a delayed version of the data signal. The amount of the delay is advantageously equal to the delay between the main peak of the channel impulse response and the leading undershoot (i.e., the precursor ISI effect) which is to be canceled. The signal which is provided to the adaptive filter (to produce the precursor ISI replica) may be based on tentative decisions generated by a symbol-by-symbol detector, and may first be converted from three levels to two levels by a three-to-two level converter. Theresultant signal (after the aforementioned subtraction), which is essentially precursor ISI-free, may then be processed by a conventional Viterbi decoder to produce the decoded symbol data.

Title: Deflectable overhead bar refuse bag opener
Inventor: NADARAJAH RAVINDRAN
IPC: B02C18/00
Filed: 1996-01-22
Abstract: A refuse bag opening device has a bag transporting conveyor positioned beneath a closed upper plate conveyor. Sharpened bars extend outwardly from the conveyor. The bars initially puncture a refuse bag from below as the bags are discharged from an infeed chute. Bars are mounted to the upper conveyor. As the lower conveyor moves the stream of bagged refuse below the upper conveyor, the upper conveyor bars move at a speed greater than that of the lower conveyor, andthus puncture and rend the refuse bags from above, ripping the bags open and scattering the refuse contained within out onto the conveyor. To lessen the possibility that a large refuse article will jam the apparatus, the bars are formed of leaf spring material and are deflectable in a cross-machine direction, preferably being stiffened by gussets which extend between the bars and a rigid base in a machinedirection.

Title: Fuel system with sight-glass
Inventor: HURNER ERWIN E
IPC: B01D35/30
Filed: 1996-01-23
Abstract: By providing a lubricating system with a strategically positioned sight-glass, it is possible to replace an fuel filter without either spilling large amounts of fuel all over or allowing for air bubbles, which can degrade the lubricating system's operation and cause siphoning. The sight-glass is positioned below the fuel inlet and outlet passages but below the filter. Thus, as soon as no fuel is seen in the sightglass, a mechanic knows that the fuel filter has been substantially emptied of fuel yet the fuel inlet and outlet are still full.

Title: Switching circuit and charge transfer device using same
Inventor: MAKI YASUHITO
IPC: H04N5/335
Filed: 1996-03-12
Abstract: A switching circuit comprising a means for holding a signal or a DC component thereof, and a switching transistor for driving the holding means, wherein another means is included for shaping the trailing edge to be more obtuse in the fall of a driving pulse applied to a gate of the switching transistor. There is also disclosed a charge transfer device comprising a charge transferrer for transferring a signal charge, a charge-voltage converter for converting the transferred signal charge into a proportional voltage, and a driver for supplying a reset pulse to the charge-voltage converter so as to reset the capacitance thereof to a predetermined potential, wherein another a means is incorporated in the driver for shaping the trailing edge to be more obtuse in the fall of the reset pulse. Since the trailing edge of the reset pulse at the time of turning off the reset is rendered more obtuse, it becomes possible to reduce the coupling portion of the output waveform where the potential of a floating diffusion or a floating gate is varied by the capacitive coupling which is derived from the parasitic capacitance between a reset drain and a reset gate.
Patent CA-2175146-A1 (CA)
Inventor: IVES HARVEY
IPC: A01K69/10
Filed: 1996-04-26
Abstract: A crab pot having improved yield.  A traditional commercial crab pot comprises  a trigger structure that rotates between open and closed portions.   The crabs enter the trap by pushing trigger members inwardly as the crabs pass through a trap opening.  The trigger members are prevented from swinging outwardly, so crabs  should not be able to leave  through the trap opening.  To bias the  trigger structure into the  closed position,  the trigger  structure comprises a counterweight  member that biases the trigger members into a position where they span the trap opening and prevent egress of crabs.   A protection structure is provided which prevents crabs from interfering with the operation of the  trigger structure.   The protection structure prevents the crabs from interfering either with the portions of the trigger members which extend below the trap opening and/or the counterweight member located above the trap opening.
