Abstract: An apparatus and method to deter circum-vention of sobriety breath tests.  As a precondition to passing the test, the invention requires an operator/test subject to apply a suction at the sample delivery port (407) within a predetermined time of delivering a breath sample thereinto.  The delay, if any, between the required sucking and the delivery of the breath sample is selected to be short thereby deterring a substitution of gas sources.  In this way, the invention effectively deters circumvention of sobriety breath tests due to attempts to supply bogus gas samples from a positive pressure gas source incapable of applying a reverse pressure gradient.

Abstract: A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a permeable, conformable material (5) to a shape-defining surface (3) of an expendable pattern (2). The permeable, conformable material, when set or stable, provides a mold with a shaped surface which is defined by, and is therefore substantially congruent to, the shape-defining surface. Upon heating, the material of the expendable pattern (2) combusts or volatilizes and thus establishes the shaped cavity mold. A molten parent metal (1) is then vaporized with a vapor-phase oxidant in such a manner as to form a ceramic body which grows into the mold cavity, and is shaped by it. The ceramic body is recovered from the mold having a shaped surface replicating the shape-defining surface (3) of the expendable pattern (2).

Filed: 1987-01-26
Abstract: A method of producing a self-supporting ceramic composite body having therein at least one cavity which inversely replicates the geometry of a positive mold of parent metal, includes embedding the mold of parent metal within a conformable bed of filler to provide therein a cavity shaped and filled by the mold. The assembly is heated to melt the parent metal mold, e.g., an aluminum parent metal mold, and contacted with an oxidant to oxidize the molten parent metal to form a polycrystalline material which grows through the surroundings of filler, the molten metal being drawn through the growing polycrystalline material to be oxidized at the interface between the oxidant and previously formed oxidation reaction product whereby the cavity formerly filled by the mold of parent metal is eventually evacuated by the metal. There remains behind a cavity whose shape inversely replicates the original shape of the mold. The method provides ceramic composite articles having therein at least one cavity inversely replicating the shape of the mold which supplied the parent metal for oxidation.

Title: Fixing device for fixing a powder image on a receiving sheet
Inventor: GERAETS JACQUES JOSEPH MARIE
IPC: G03G15/20
Filed: 1989-10-27
Granted: 2001-01-09
Abstract: A fixing device for fixing a powder image on a receiving sheet in a fixing nip formed by a fining roller and a pressure roller which has a lower flexural stiffness than the fixing roller. These rollers are pressed against one another by a stationary cushion filled with compressed air and pressing against the pressure roller in a pressure zone situated opposite the fixing nip. When the pressure roller and the fixing roller are driven, tangentially directed frictional forces are exerted on the pressure roller that causes the presssure roller to deflect against a curved support surface which limits the deflection. The pressure roller deflected in the operative position causes a receiving sheet fed through the fixing nip to be stretched in a direction transversely of the direction of conveyance to eliminate any bubbles or corrugations in the receiving sheet.

Title: Method and apparatus for detecting deviation of motor speed from frequency of power supply
Inventor: WYCOFF DAVID C
IPC: H02P23/08
Filed: 1990-01-26
Granted: 1995-12-12
Abstract: An adjustable frequency motor drive system for a hoist is disclosed in which the frequency of the power supply to the motor can be selectively varied and the speed of the motor will follow the varying frequency at a slip speed relative to the frequency.  The slip speed of the motor may not exceed a value beyond which the motor can control the hoist load.  Accordingly, a frequency value based on the frequency of the power supply to the motor is selected as the frequency which is not to be exceeded by the motor speed expressed as a frequency. Signals representative of the actual motor speed and the selected frequency value are compared and,  if the signal representative of the motor speed exceeds the signal representative of the frequency value which is not to be exceeded, an output signal is produced which may be used to apply a brake which stops and holds the motor and hoist and thereby maintains the load suspended.  A motor speed deviation time period may also be provided and the hoist brake not applied to the motor until the time period is exceeded.

Abstract: Apparatus and a method for folding flaps onto panels formed in folded box blanks, particularly those constructed from corrugated cardboard. As a blank advances along a paper line, a first station engages leading edges of the flaps and forces the flaps into an intermediate plane representing a partial folding operation. Then a second station controls the relative velocities of the flaps along the paper line with respect to the panels to compensate for skew that can occur in other stations. A final station completes the folding operation. The resulting fold is made about an axis, or fold line. If the flap is to be folded about a prestamped score line, the fold and score lines are coextensive. Typically the flaps are folded 180.degree. and the first station produces intermediate folds that are displaced 90.degree. from the panels.

Title: Rotary selector valve
Inventor: JONES JEFFREY A
IPC: F16K31/524
Filed: 1990-07-18
Granted: 2000-06-06
Abstract: A multi-port valve internally supports a rotatable trunnion having an elbow passage between a nozzle portion of the trunnion and a lower end outlet that communicates with a test port of the valve body. The outer end of the nozzle has an axially reciprocable hollow seal piston with a seal support ring whose outer face is formed with an endless groove to receive an O-ring. An actuating shaft is coaxially mounted in an upper end of the trunnion and has a lower end with an eccentric pin engaged in a slot of the seal piston to reciprocate the seal piston into and out of sealing registration around a port selected by rotation of the trunnion. External ends of the actuating shaft and trunnion are respectively drivably coupled to a coaxial sprocket wheel and geneva wheel. A housing on top of the valve contains an input rotor fitted with a cam and a drive roller for engaging radial slots of the geneva wheel alternately with cam engagement of the dwell notches of the geneva wheel.      Concurrently and in advance of forward rotation of the geneva wheel, a rotor driven seal actuating yoke at a free end engages one of a series of radial slots of the sprocket to rotate the sprocket in a retrograde direction to disengage the seal. When the yoke is disengaged, a decent mechanism temporarily locks the geneva and sprocket wheels together for co-rotation in a forward direction as the geneva drive roller again comes into engagement with the geneva wheel. After the nozzle has been advanced one step, further rotation of the input rotor advances an arm independently pivotally mounted on the yoke to compress a spring mechanism to bias the yoke and sprocket to compress the seal on a seat around the next port.
