Abstract: Apparatus and with a horizontally stretched flexible membrane is used to sealingly support a lower, openable end portion of an air-permeable sack containing powder material.  A conical funnel-like sealable portion of the apparatus  immediately  beneath  the  membrane  may  be connected to a mechanism for applying a suction.  This suction uses inward air flow from the ambient atmosphere through the air-permeable wall of the sack and the powder material  contained therein,  to generate a  fluidized air/powder material outflow from the lower opening of the sack.   The funnel-like element guides this flow and enables transfer of the air-fluidized powder material flow.  To form a slurry, a conventional disperser/mixer mechanism dipped into a quantity of liquid in a tank may be connected to a suction duct to apply the desired suction.   Fluidized air/powder material flow then is intensely and rapidly stirred with the liquid to form a slurry.

Granted: 1996-10-15
Abstract: A system is described that uses acoustic energy to position an object, which simplifies the application of forces in defined directions to the object and which enables the application of large forces to the object. The system includes transducers (21-24, FIG. 1) that direct separate acoustic beams (31-34) at the object (12), with the system constructed so the beams do not create standing wave patterns. A plurality of beams whose phases at the object are not closely controlled, are directed at different surface areas of the object so the beams do not substantially overlap at the object and create possible canceling effects. A very large force is applied to the bottom (124, FIG. 8) of an object lying in a gravity environment, by directing a plurality of beams (141-145) at the same area at the bottom of the object, and with the beams being controlled so they are substantially in phase at the object area. This plurality of beams can also replace one or all of the transducers (21-24, FIG. 1) to provide much stronger forces to position and manipulate the object. The wavelength (B, FIG. 2) of the acoustic energy in each beam is preferably much less than one-tenth the diameter (C) of the object in order to obtain efficient momentum transfer of energy to the object.

Title: A genetically engineered cell line for detecting infectious herpes simplex virus and method therefor
Inventor: OLIVO PAUL D
IPC: C12Q1/68
Filed: 1993-06-17
Granted: 2002-09-03
Abstract: A diagnostic assay for detecting the presence of an infectious herpes virus in a specimen and a genetically engineered cell line for use in such assay are disclosed. The cell line used in the assay expresses a reporter gene only if infectious herpes virus is present in the specimen. The assay involves inoculating a DNA-transfected cell line with a specimen suspected of containing a herpes virus, allowing a sufficient period of time for the herpes virus infectious cycle to proceed, and detecting and quantifying the number of herpes virus-infected cells to determine the number of infectious herpes virus virions in the specimen. The cell line is a DNA-transfected cell line susceptible to infection by a herpes virus which is stably transformed with a chimeric gene compris-ing a herpes virus inducible promoter and a gene coding for an enzyme, the expression of the enzyme being dependent upon and quantitatively proportional to the presence of herpes virus. A kit for such assay is also provided.

Granted: 2004-01-27
Abstract: An engine (1) for driving a piston arrangement (13, 14, 15) for pumping water from an inlet (26) to an outlet (27) at a high-er level. The engine (1) includes a hollow housing (2) having an inlet (3) and an outlet (4) between which a liquid passes, the hous-ing (2) at least partly enclosing a chamber (7) through which the liquid flows from the inlet (3) to the outlet (4). A movable wall (6) is mounted in the housing (2) and partly defines the chamber (7). A valve (16) is provided to open and close the outlet (4) so that, when it closes, liquid in the chamber (7) is suddenly decelerated, producing an increase in pressure in the chamber to force the wall (6) to move in a direction so as to increase the volume of the chamber (7). After the initial increase in pressure, the water relaxes and the pressure decreases to such an extent that a spring (19) opens the valve (16) and a spring (10) returns the wall (6) to the position of decreased volume of the chamber (7). Thus, the wall (6) is caused to reciprocate under the influence of the pressure of the liquid increasing and decreasing as the valve (16) is opened and shut.

Abstract: A coin security system is provided which electronically monitors coins passing into a portable coin collection security bag in order to discourage pilferage of coins stored in the collection bag.  A memory chip associated with the bag, or with a mounting member connected to the bag, is in communication with the central data processor in the vending machine circuit when the collection bag is mounted and is receiving coins.  When the portable collection bag is disconnected, the memory chip becomes disconnected from the circuit and breaks the circuit, causing the vending machine to shut down.  This automatic shutdown feature reduces another kind of pilferage by discouraging the depositing of coins into the vending machine when the coin collection security bag is not in place.

Abstract: Disclosed is a phase detection apparatus for accurately calculating the phase of an input digital complex baseband signal point independently of its amplitude value, without requiring any large-capacity arc-tangent table memory and within a practical calculation time.  This phase detection apparatus rotates the phase of the input signal point in a clockwise direction by a predetermined angle and determines whether the rotated signal point agrees with a reference phase point.  If the rotated signal point leads the reference phase point, the signal point is further rotated by an angle onehalf of the predetermined angle.  If the rotated signal point lags behind the reference phase point, the signal point before the rotation is rotated by a half angle of the predetermined angle.   Rotational angles, 180°, 90°, 45°,..., for the individual rotations are stored in a table.  If the rotated signal point agrees with the reference phase point after the rotation processing is performed several times, or, even if the two points do not agree, if all of the rotational angles stored in the table are used in the rotation processing, the sum of the angles rotated so far is output as the phase of the input signal.
