Title: Device for tearing refuse bags
Inventor: EIDE RUSSEL L
IPC: B65B69/00
Filed: 1992-06-18
Abstract: TITLE Device for Tearing Refuse Bags ABSTRACT OF THE DISCLOSURE    A device (10) for continuously tearing bags containing material such as refuse is disclosed including elongated, flexible flails (14) secured to a rotatable rotor (12). The flails (14) are formed in the preferred form from steel wire rope cables (28) having their free ends captured within thick wall tubing (34) swedged thereon.  In addition to keeping the ends from fraying, the tubing (34) acts as a centrifugal weight and hammer for the cable (28).  The rotor (12) is formed of L-shaped plates (16) attached together to extend quadrantly from and form a square tubular beam surrounding the axis of rotor (12). The flails (14) extend through apertures (36) formed in the leg portions of the plates (16) defining the square tubular beam and are secured to the leg (18) of the plates (16) spaced from the square tubular beam by cable clamps (38) having U-shaped bolts (40) extending through apertures (50) formed in the legs (18).  The second legs (22) of the L-shaped plates (16) extend generally parallel to the U-shaped bolts (40) and protect the cable clamps (38).  As the bags delivered by a conveyor (58) to the device (10) fall under gravitational forces from the end thereof, the falling bags are struck in the same direction by the flails (14) which are rotated in vertical rotational planes to tear the bags and release the contents thereof.

Title: Continuously acting one-way satellite roll-yaw attitude control method and device
Inventor: FLAMENT PATRICK
IPC: G05D1/08
Filed: 1992-06-26
Abstract: ABSTRACT OF THE DISCLOSURE Roll  and  yaw  attitude  control  method  for  a satellite stabilized about its roll, yaw and pitch axes and  comprising  a  momentum  wheel  system  generating  a continuous angular momentum substantially parallel to the pitch  axis  and  having  a  variable  component  at  least approximately  parallel  to  the  roll-yaw  plane  and  a continuously acting  actuator  system  in which  the  roll and/or yaw attitude of the satellite is sensed, control signals are applied to the momentum wheel system that are produced  by  a  fast  control  loop  using  a  known  fast control law and second control signals are applied to the continuously acting actuator system that are produced by a slow control loop using a known slow control law.  The continuously acting actuator system is loaded in a fixed direction  of  the  satellite  parallel  to  the  variable component if the latter has a fixed direction.  At least a  first  additional  control  signal  is  applied  to  the momentum wheel system,  chosen to yield a value of the fixed direction component of the angular momentum adapted to compensate in the long term drift of a second fixed direction component of the angular momentum.   A second additional control signal is applied to the continuously acting  actuator  system  that  is  adapted  to  cancel  the effect of the first signal on the attitude with respect to the second fixed direction.

Title: Nozzle mounting in atmospheric diffusers
Inventor: GOLSTON STEFAN
IPC: D21D5/00
Filed: 1992-07-30
Abstract: ABSTRACT         Nozzle breakage in an atmospheric diffuser for treating paper pulp is precluded by mounting the nozzle to the rotating scraper arm by a connection which will break when the nozzle is subjected to a drag force of about 50% of the force that will break the nozzle.  The connection preferably includes a pivot connection of a nozzle extension at one side of the arm, and a shear pin connection of the extension at the end opposite the pivot connection.  An oblong nozzle is integral with the nozzle extension, with the fluid introducing openings of the nozzle remote from its connection to the extension.  The amount of pivotal movement of the nozzle when the shear pin breaks is limited to about 15°-26° so as to prevent the nozzle from contacting an annular extraction screen of the diffuser.

Abstract: Attorney Docket No.  NS18695 PARTIAL ISOLATION OF POWER RAILS FOR OUTPUT BUFFER CIRCUITS          Abstract An output buffer circuit (10) delivers output signals of high and low potential levels at an output (VOUT) in response to data signals at an input (VIN). The output buffer circuit comprises an input stage (12) coupled between a relatively quiet power supply rail (VCCQ) and a relatively quiet power ground rail (GNDQ), and an output stage (14) coupled between a relatively noisy power supply rail (VCCN) and a relatively noisy power ground rail (GNDN).  A first coupling resistor (R5) is coupled between the relatively quiet and noisy supply rails (VCCQ, VCCN) for reducing  cc droop in the relatively noisy supply rail (VCCH) which in turn reduces output step in voltage during transition from low to high potential level (LH) at the output (VOUT). The first coupling resistor (R5) has a low resistance value selected for partially coupling the supply rails while maintaining partial isolation for maintaining input dynamic threshold levels for other non-switching quiet output buffer circuits coupled to a common bus.  A second coupling resistor (R5A) is coupled between the relatively quiet and noisy ground rails (GNDQ,GNDN).  The second coupling resistor (R5A) has a low resistance value selected for partially coupling said ground rails while maintaining partial isolation also protecting input dynamic threshold levels of quiet outputs.  The first coupling resistor (R5) is coupled between supply rail bond pads (20,22), while the second coupling resistor (R5A) is coupled between ground rail bond pads (30,32).  The power rail bond pads (20,22) (30,32) are coupled respectively to split leads (24,25) (34,35) of a split lead leadframe merging respectively to a common VCC pin (28) and a common GND pin (38).

Filed: 1993-10-01
Abstract: An exercise device having a coupling member movable by the user between rest and end limit of travel positions, a constant weight, and a weight-lifting arm operatively connected to the weight and movable through a vertical plane to move the weight between rest and elevated positions corresponding to the rest and end limit positions of the coupling member. The device further includes a pivot arm pivotally movable through a pivot arm plane having a user-selectable angular orientation to transmit a selectable force between the coupling member and weight dependent upon the selected angular orientation. A link arm is connected between the pivot arm and the weight-lifting arm to transmit force therebetween. The pivot arm is pivotally attached to a rotatable pivot arm support which is selectively rotated by a lever arm moved by an electric motor and screw arrangement to selectively change the angular orientation of the pivot arm plane. The pivot arm plane is movable into a non-loading horizontal orientation where movement of the pivot arm transmits substantially zero force between the coupling member and the weight-lifting arm. The pivot arm plane is adjustable to produce a true zero weight setting on the coupling member.      The exercise device provides infinitely variable adjustment of the loading on the coupling member within the range of possible weight settings even while an exercise is in progress.

IPC: A47G25/48
Filed: 1993-11-29
Abstract: ABSTRACT    A garment hanger having an improved locking clip, and a spring locking clip for use with clamp-type garment hangers is provided.  The improved U-shaped locking clip includes inwardly extending ribs on the rear member that extend from the upper portion of the rear member downward close to the distal end of the rear member.  The extension of the ribs toward the distal end of the rear member precludes the distal end of the rear member or any burr disposed thereon from interfering, digging into, binding, or otherwise engaging its associated exposed surface of the rear jaw of the clamp assembly.  By precluding any engagement of the distal end of the rear member with the exposed surface of the rear jaw, the improved clip operates smoothly and is easier for the consumer to use.
