Title: A compaction mechanism for a compaction chamber of a garbage truck
Inventor: TETZ WARREN
IPC: B65F3/20
Filed: 1997-12-16
Abstract: A compaction mechanism uses cables to move a compaction plate within a compaction chamber of a garbage truck. Cable guide pulleys are positioned adjacent a first end and a second end of the compaction chamber. Each cable has a first end and a second end, both of which are secured to the compaction plate. A winch-like drive assembly is used to concurrently move the cables to pull the compaction plate.

Title: Double rotating mixing system
Inventor: NIEMI WALTER
IPC: E01C19/10
Filed: 1998-03-10
Abstract: The disclosed invention provides a drying and mixing plant for mixing material with an additive comprising a tapered inner drum and an oppositely tapered outer drum attached together concentrically and rotated as a unit. A burner directs a hot air stream into the small end of the inner drum. Material is fed into the small end of the inner drum, where impellers lift it and drop it into the hot air stream and move the material through the inner drum aided by the downward taper of the inner drum. The material exits the inner drum and enters the outer drum, where an additive material is introduced and mixed with the material. The receiving end of the outer drum is enclosed in a shroud, which directs the airstream through the chamber between the drums, the chamber having an expanding cross section which slows the air down allowing fines to precipitate out. The device may include nozzles for spraying water across the path of the air stream and material flow, and further may include, for fluid additive materials, additive nozzles spraying the additive material across the path of the air and material. The device is particularly suitable for mixing asphalt paving mix.

Title: Method and apparatus for high capacity rotary cheese shredding
Inventor: SCHNEIDER ALAN L
IPC: B26D1/29
Filed: 1998-05-11
Abstract: A method and apparatus for shredding cheese is disclosed which is capable of producing relatively precise square cross-section cheese shreds of a desired length.  The apparatus is capable of simultaneously shredding multiple cheese blocks for high capacity cheese shredding.  The length of the cheese shreds can be altered as desired, as well as the width and height to produce cheese shreds having a rectangular cross-section.  A containment center is used to feed the blocks of cheese toward the cheese shredding apparatus.  A series of horizontally mounted sectioning knives are at a front end of the containment center to section the cheese block into predefined lengths, thereby defining the length of each cheese shred.  The cheese shredder includes multiple slicing and peeling assemblies mounted over a series of openings in a rotatable disk.  Each slicing and peeling assembly includes a number of rakers having outwardly projecting slicing blades to vertically score a sectioned block of cheese.  The slicing and peeling assemblies also includes a peeling knife arranged transversely to the slicing blades to peel the sectioned and scored cheese block.  The individual cheese shreds are then fed through openings in the rotatable disk and fall into a discharge chute below.

Title: Direct sequence spread spectrum dsp system
Inventor: ROUQUETTE ROBERT E
IPC: H04B1/707
Filed: 1996-11-15
Abstract: A direct sequence spread spectrum (DSSP) DSP implementation technique utilizing a unique combination of multiple filters (DSP Channel Fltr), transforms, despreading algorithm and spectral compression, all in a single coefficient set, providing a highly efficient system. Reallocatable computational resources allow for frequency uncertainty in the transmitter, without the typical excessive noise bandwidth penalties. The present system further contemplates a unique energy detection algorithm for discerning spread spectrum while in the search mode, utilizing discrete sampling data sets to increase signal strength, reducing noise, while changing the relative phase of the received chipping code with respect to the received signal. The spectral compression of the spreading sequence is achieved by representing the PRC as an array of two, complementing fractional coefficients. The PRC code is filtered to achieve the required spectral compression characteristics, resulting in minimal despreading loss, while providing interference rejection of CW signals greater than 1.5 MHz from the center IF frequency.

Title: A method and device for processing sampled analogue signals in digital bicmos process
Inventor: TAN NIANXIONG
IPC: G11C27/02
Filed: 1997-06-04
Abstract: In a digital BiCMOS process the storage capability of MOS transistors and the large transconductance of bipolar transistors can be utilized in such a way, that the speed is primarily determined by the capacitance seen by the MOS transistor (4) and the transconductance of the bipolar transistor (5). The advantages over the prior S1 technique in CMOS are higher speed, smaller errors and higher accuracy. The advantages over other techniques in BiCMOS are smaller errors and higher accuracy. The unique feature of the invented technique is the combination of high input impedance of the MOS devices and high transconductance of the bipolar devices, where both devices are only available in BiCMOS process and not in the CMOS process.

Filed: 1997-09-05
Abstract: A shear separation system or method uses shear lift forces and permeate drag forces to separate substances having a size less than a predetermined separation size from substances having a size greater than the separation size. The balance of the drag forces and lift forces affects a predetermined separation size in that the balance of forces retards the transmembrane passage of substances larger than the separation size yet allows substances smaller than the separation size to pass through the permeable membrane. The shear separation device, method and system can be employed to separate or concentrate from a process fluid substances larger or smaller than the predetermined separation size.

Title: Dual loop frequency and power control
Inventor: KEPLEY KEVIN PAUL
IPC: A23L27/00
Filed: 1997-08-22
Abstract: The invention is an improved phacoemulsification probe drive circuit for supplying electrical power to an ultrasonic transducer. The drive circuit has a power control loop (1412) and a frequency control loop (1413). The power control loop (1412) has a variable gain amplifier (1416) whose output is an input to a power amplifier (1417). After the power amplifier amplifies power, power is delivered to a transformer (1436) and, thereafter, to a transducer (1439). The voltage and current applied to the primary of the transformer are sensed to generate a signal proportional to the power (real or apparent), and the result is compared against a power command originating from a foot pedal. Once compared, the result of this comparison is sent to a first controller which acts upon the information by sending a corrective signal to the variable gain amplifier.
