Title: Mixing and discharge capsule
Inventor: GREEN RUSSELL D
IPC: B65D81/32
Filed: 1987-05-05
Granted: 1991-04-23
Abstract: A combination mixing and discharge capsule for storing separate ingredients which are to be mixed together prior to use and including a container body for one ingredient closed at one end by a slidable piston and the opposite end being displaceably received in a cup-shaped cap which forms a second compartment with a perforated wall of the container body opposite the end containing the piston for receiving a frangible pillow containing a liquid second ingredient to be mixed with the ingredient in the body. The cap has a discharge nozzle extending axially therefrom and when the cap is displaced farther onto the body the innermost wall of the pillow is burst to cause the discharge of the liquid ingredient through the perforated wall end into the container body for mixing with the ingredient therein. After mixing is completed, a puncturing rod is inserted into the nozzle to puncture the opposite wall of the pillow and, when the rod is withdrawn the piston is moved toward the perforated wall to effect discharge of the mixed ingredients through the nozzle.

Granted: 1992-05-19
Abstract: FLUID POWER TRANSFER DEVICE          ABSTRACT         A fluid power transfer device includes a pair of rotors and vanes mounted for rotation in a hollow housing having an equatorial plane wherein conical faces of the rotors rollingly engage each other to form a line contact and wherein a hinge pin  which  hingedly  connects  the  vanes  is  con-strained to rotate in the equatorial plane of the housing.   A sun gear sector is connected to the side of each vane opposite the hinge pin.  A ring gear sector is connected to the inner end of each output shaft to rotate therewith.  A pinion planet gear connects each ring gear sector to each sun gear sector so that the pinion planet gears rock back and forth between their respective sectors as the vanes rock about the hinge pin.   The pinion planet gears are elongated and confine the hinge pin to the equatorial plane.   The pinion planet gears also act as splines to transfer torque.  Each rotor includes  a pair of rotor portions  and an interconnecting outer band.  The outer bands also have  conical  faces  which  rollingly  engage  each other to further form the line contact.  The outer bands are slidably received within grooves formed on the inner surface of the housing.  Each of the hinged vanes is received and extends towards its gear sector through  a  channel  defined  by  its respective rotor portions.  The conical faces of the rotors and the housing cooperate to define a working  chamber  which  is  divided  into  working compartments  by  the  hinged  vanes  and  the  line contact.  The rotors and the vanes transfer power between their respective shafts and an operating fluid introduced into one of the working compart-ments.

Abstract: ABSTRACT          A modular endless track drive system for use on a track vehicle such as a bulldozer is made up of a number of polymeric drive modules  interconnected with polymeric master links.   Each drive module includes a plurality of drive members with lateral frictional drive faces for engagement with a drive wheel, each master link having similarly configured drive faces.  The drive wheel is provided with drive surfaces shaped to match the shape of  the  lateral drive  faces  on the drive modules  and master links and/or a sprocket for engaging with addi-tional drive faces on the drive modules and master links.          A drive module is made by molding a polymeric multiple drive member structure atop a plurality of base portions, encasing  one  or more  connecting members  therein with their ends  exposed.   The master links are made in a similar fashion, but with upper and lower base portion parts for fastening the drive module connector members therebetween to form an endless track.   The system is readily  installed  by  assembling  the  necessary  drive modules and all but one of the master links to form a track with two disconnected ends,  laying the assembled track linearly across the ground,  positioning a track vehicle thereover, looping the track over the wheels of the track vehicle, and installing the final master link to form the endless track.   Repairs to the system are made  by  simply  removing  and  replacing  broken  drive modules and master links in situ.

Abstract: CONTROL LOOP INSTABILITY DETECTION AND          CORRECTION APPARATUS                      ABSTRACT The  control  loop  instability  detection  and correction apparatus monitors an error signal produced by a control system to detect any instability in the control loop before the instability significantly affects the performance of the controlled apparatus. This is accomplished by monitoring the error signal to detect a change in the error signal greater than a predetermined limit and to tabulate the number of times the change in the error signal is in excess of the predetermined limit over a fixed period of time. Whenever the change in the error signal is in excess of the predetermined limit, it is reduced in magnitude to a predetermined value and this resultant signal is applied to the controlled apparatus in place of the originally generated error signal.   In addition, during each sampling time interval, the result of this comparison  is  used  to  increment  or  decrement  a counter.   If the change in the error signal is in excess of the predetermined limit, the counter is incremented to indicate the number of times that the change  in  the  error  signal  has  exceeded  the predetermined limit.   If,  on the other hand,  the change  in  the  error  signal  is  less  than  the predetermined limit the counter is decremented to indicate that the error signal is within the allowable limits of magnitude.  If this count tabulated by the counter exceeds a predefined threshold,  an alarm indication  is  activated  to  note  possibility  of instability  in  the operation  of  the  controlled apparatus.
