Abstract: The present inventon relates to an angle station (3) for lateral angular displacement of an endless conveyor belt (2) in a conveyor system (1). The angle station (3) comprises a belt guide means (7) in the form of a plurality of large diameter guide roll-ers (4, 18) mounted in support brackets (19) on a support structure (20,21) with said rollers (18) substantially clear of the support structure (20, 21). The guide rollers (18) are generally elongate and arranged substantially normal to a substantially helical path-way Z for the belt (2) around the belt guide means. The guide rollers (18) are disposed in axially and laterally, closely spaced rela-tion, so as to define a generally continuous support for a conveyor belt (2) in use of the angle station (3) which support is substan-tially non-angular in cross-section along the helical pathway Z. The present invention also provides a roller support bracket (19) for use in an angle station (3) of the invention as well as a guide roller unit comprising a guide roller (18) mounted in such a bracket (19).

Title: Water-based water repellent coating compositions
Inventor: SCARBOROUGH VICTORIA DENISE
IPC: B27K3/34
Filed: 1994-04-13
Granted: 1997-09-30
Abstract: There is provided a water based water repellent coating composition, method of making and method of use.  The coating composition comprises an emulsion having water as the continuous phase and, as the discontinuous phase, droplets of a nonvolatile organic water repellent composition, the emulsion containg an emulsion stabilizing amount of a hydrophobically modified polyacrylic acid polymer wherein the viscosity of the emulsion is less than about 100 Cps and the particle size of the droplets is less than about 50 microns.  The relatively low viscosity and small particle size provides for easy application and excellent penetration into porous substrates.  The process of making the compositions involves the making of a conventional emulsion of this type and then high kinetic energy processing so as to produce the desired viscosity and particle size.  The method of use involves the application of the composition to a substrate followed by evaporation of the water and any volatile components from the composition.

Abstract: An apparatus and method provides additional logic in both execution units of a dual execution unit processing in order to   determine   if the   instruction   is   interruptible.          Additionally,  backout  logic is  provided  for  saving  the contents of unique registers.  The backout logic uses two decodes to determine if the instruction currently executing modifies the unique registers.  It is possible for a single instruction to modify more than one unique register.  The backout logic of the present invention resides in both of the execution units and particularly in the unit which contains the  unique  register  being  modified  by  the  executing instruction.  If  an  instruction  is  being  executed  which modifies one of the unique registers, then the contents of that register are saved in a backout latch. A cancel signal is then  provided  if  the  interruptible  instruction  executes without causing and interrupt. However, if the interruptible instruction does cause an interrupt, then the contents of the backout latch are reloaded into the execution units.

Abstract: A caliper profile control system for a paper machine provides reduced start up times after sheet breaks to bring the caliper profile across the sheet to within the desired limits. The method comprises the steps of scanning at predetermined intervals across the width of the paper sheet to monitor thickness error of the sheet from predetermined limits and change in the thickness error between the intervals, in each of a plurality of zones across the sheet. A control change signal is determined for each of the zones based on the error and the change in error using an exponential function of the magnitude of the error to maximize the change in the error and reduce integral action when the error is large.      The control signal is used to reduce the error in each zone and the integral action is increased as the error decreases until the predetermined limits are met.

Title: Prosthesis delivery
Inventor: RAVENSCROFT ADRIAN C
IPC: A61F2/90
Filed: 1994-05-18
Granted: 2006-06-06
Abstract: This invention provides smooth delivery and accurate positioning of prostheses in the body. In embodiments, systems are provided that include elongate members (16) extending generally along the axis of a supporting catheter (4) to free ends (17). The elongate members (16) extend through openings (10) in the prosthesis (6) to maintain the position of the prosthesis (6) on the catheter (4). The prosthesis (6) can be released from the catheter (4) by relative axial motion of the catheter (4) and the elongate members (16) such that the free ends (17) are removed from the openings (10) in the prosthesis (6). In embodiments, the elongate members (16) hold the distal end of a self-expanding stent (6) at a desired axial location and in radial compaction as a restraining sheath (8) is withdrawn. The friction between the sheath (8) and the stent (6) puts the stent (6) under tension, which reduces the radial force on the sheath wall, allowing smoother retraction. Proximal portions of the stent radially expand and axially shorten.

Abstract: An inflatable vehicle occupant restraint (12) includes a first fabric panel (60), a second fabric panel (62), and a seam (64) at which the fabric panels (60,62) are fastened to each other.  The restraint (12) further includes a vent opening (128) which interrupts the seam (64) to direct inflation fluid to exit the restraint (12) between the fabric panels (60,62).  The restraint (12) is inflated between a vehicle seat (16) and an adjacent vehicle door (18) upon the occurrence of a side impact collision, and protects an occupant of the seat (16) from being forcefully struck by the door (18).  The vent opening (128) directs the inflation fluid to exit the restraint (12) in a direction which is perpendicular to the direction in which the door (18) is moved toward the seat (16) by the side impact collision.  As a result, the flow of inflation fluid which is directed from the restraint (12) through the vent opening (128) is directed away from the occupant and is not blocked or impeded substantially by the seat (16) or the door (18).

Abstract: An overload protector is secured to a robot arm and a tool to protect the tool from being overloaded or forced into an abnormal position. A rocker assembly is located within the cavity in the protector and the cavity is pressurized in order to force a wall of the rocker assembly into a sealing relat-ionship with a wall of the cavity. The rocker assembly has a peripheral wall in which a number of semi-conical recesses are formed. A like number of semi-conical detents are formed in the wall of the cavity. The detents are accommodated in the recesses when the rocker as-sembly is in a sealing relationship with the cavity wall. When the tool is overloaded or forced into an abnormal position the rocker assembly rocks in the cavity with result-ing leakage of fluid from the cavity and a drop of pressure. A pressure switch detects that drop and signals the robot to stop.
