Title: Self-calibration technique for high-speed two-stage and pipelined multi-stage analog-to-digital converters
Inventor: GU ZHIQIANG
IPC: H03M1/16
Filed: 1993-04-27
Abstract: ABSTRACT OF THE DISCLOSURE   The self-calibration technique presented in this disclosure is designed for high-speed two-stage and pipelined multi-stage A/D converters (ADCs), and n is absolutely unique in world-wide literature or markets at the time of this application. The technique is found to be very helpful in improving the conventional design of the ADCs toward higher speed, lower power dissipation and smaller device size by reducing stringent component-mismatching requirement in designing very large scale integration (VLSI) ADC chips. The technique provides a non-switched-capacitor (non-SC) robust alternative for VLSI implementation of critical parts in two-stage and pipelined multi-stage ADCs.   The technique comprises an adaptive offset shaping technique for flash A/D subconverters (ADSCs) of all stages and residue-based error correction technique for digital-to-analog subconverters (DASCs) of all stages in two-stage or pipelined multi-stage ADCs. The critical part of the adaptive offset shaping technique for ADSCs is an adaptive self-trimming process. The self-trimming process is delta-modulation based, and is carried out at each time instant by adjusting voltage thresholds of two successive comparators in an ADSC when digital output from the lower one is set to HIGH. Gain error in interstage sample-and-held amplifier (SHA) of a two-stage or pipelined multi-stage ADC can be automatically counteracted during the threshold self-trimming. The residue-based error correction technique uses overflow/underflow code information obtained from quantizing a residue signal from each previous subconversion stage of a two-stage or pipelined multi-stage ADC, and the threshold errors of ADSC and DASC in the previous stage are corrected solely based upon overflow and underflow of the residue signal.

Title: Lubrication system for a conveyor belt
Inventor: HOFFMAN PHILIP L
IPC: F16N7/24
Filed: 1993-09-29
Abstract: LUBRICATION SYSTEM FOR A CONVEYOR BELT                  Abstract of the Disclosure An optical inspection system (10) has a conveyor belt (18) that turns at a non-rotating turning bar (22). An inner surface (20) of the conveyor belt contacts a turning surface (22T) of the turning bar.  A reservoir (60) for holding a lubricant (62), such as water, is formed by a free surface (22F) of the turning bar, two reservoir side walls (54, 56), a free surface (52F) of a feed bar (52), and a lower surface (58).  The feed bar has orifices (69) for discharge of the lubricant into the reservoir and is connected to a source of lubricant subject to volume regulation.  When the conveyor belt is in operation, the volume of lubricant suppled to the reservoir keeps the line of contact (22L) between the inner surface and the turning surface covered with lubricant.  Rods (64, 66) regulate the flow of lubricant so as to maintain adequate  coverage with lubricant of the region (46) where the conveyor belt turns over the turning bar and of the line of contact between the inner surface and the turning surface.  The top (22H) of the turning bar is a distance (H) lower than the common level of the top (52H) of the feed bar, the top of the side walls, and the tops (64H, 66H) of the rods.  The volume of lubricant supplied to the reservoir through the orifices is regulated so that the supply slightly exceeds the outflow of lubricant between the inner surface and the turning bar.  Any excess flow of lubricant flows over the tops of the rods where they are not in contact with the inner surface of the conveyor belt and is captured in a catch pan or pans (72).  The conveyor belt may alternatively cause the articles to move through a desired region, such as to the surface of another conveyor belt in a belt-to-belt transfer system.

Patent CA-2114219-A1 (CA)
Inventor: HILL WOLFGANG
IPC: H02K3/50
Filed: 1992-07-29
Abstract: Known flat winding layers that can be prefabricated and inserted into soft magnetic bodies insufficiently utilize the available space in the grooves and winding overhang of polyphase machines and thus increase the volume and weight of the machine. A new winding design allows high power and force densities to be obtained, thanks to the utilization of the whole available space, and are economic to produce. For that purpose each winding layer (4d) is composed of several conductor lanes (22-24) whose number corresponds to the number of phases. The height of the conductor lanes is reduced at the points (25-33) where they intersect,due to the fact that the conductors are mutually offset, and thus pass over each other inside the layer. By variably adapting the width of the conductor the space in the winding overhang through which the magnetic flow is directed in the soft magnetic body is utilized. The space available in the winding overhangs is completely utilized thanks to double winding layers of which each second layer mirrors the first and is offset by a pole pitch with respect to the first. The winding is suitable fox motors and generators whose volume and weight can be advantageously reduced.

Title: Apparatus and method for making absorbent products containing a first material dispersed within a second material
Inventor: GRIFFOUL THOMAS
IPC: A61F13/15
Filed: 1994-06-01
Abstract: An apparatus and method for making absorbent products in which a first material, such as absorbent fluff formed from wood pulp, is introduced into a vacuum forming chamber. A portion of the fluff is deposited into the cavity of a mold transported through the forming chamber by a forming wheel so as to form a layer of pure fluff within the bottom of the mold cavity. A second material, such as superabsorbent particles or heat stabilized fibers, is introduced into the forming chamber so that streams of the first and second materials collide within a mixing zone.      As the mold continues it travel through the forming chamber, a mixture of first and second materials from the mixing zone is deposited within the mold cavity, thereby filling it. The portion of the mixture that extends above the surface of the mold is scraped off by a scarfing brush that directs the mixture back into the mixing zone, thereby creating turbulence that ensures thorough mixing of the two materials. The result is an absorbent product having a first layer formed by pure first material and a second layer formed by a mixture of the first and second materials.
