Abstract: ABSTRACT      The invention relates to a method for concentrating precious metals and heavy minerals in sand or gravel deposits and an apparatus for carrying out the method.  The method comprises pre-classifying the raw material suspended as a slurry in water by means of screen means into two to six fractions.  Each fraction as a slurry in water is provided with a flow velocity of about 0.25 to about 0.50 m/sec. over a length of about 3 m.  The flow is retarded and stopped to provide a plurality of volumes separated from each other in the direction of flow in the lower range of the overall height of the fluidized bid.  Each flowing volume is treated during the retarded flow condition in its lower range of height be means of thrust and suction shocks acting on the flowing volume from below.  The apparatus of the invention provides in a raw material feed station a vibrating feeder trough which is sidewardly open at its discharge end for the conveying and disintegrating of agglomerated bulk material.  The sidewalls of the trough have inwardly bent upper edges so to partially extend over the conveying bottom.  Nozzles for pressurized air or water jets are provided at the lower side of the said bent upper edges.  The feeder trough has associated behind it a forescreen for separating the deads and a collecting tank beneath said forescreen for collecting the produced slurry.

Abstract: ABSTRACT OF THE DISCLOSURE          The specification discloses a vehicle window assembly including a slidable window glass supported by and guided along only one edge of the glass.  More specifically, the assembly comprises a window glass, a molded guide bonded to one edge of the glass, and a pillar defining a channel in which the guide is slidingly received.  The pillar and guide cooperate to permit the guide to move axially within the channel and to prevent the guide from passing transversely out of the channel so that the window glass must travel in a linear path.  Also disclosed is a latch supported by the glass and extending through the guide.  The latch includes an actuating portion located outside the pillar and a catch portion located and hidden within the pillar.

Abstract: INTERNAL COMBUSTION ENGINE SPARK TIMING CONTROL INCLUDING    PEAK COMBUSTION SENSOR          Abstract of the Disclosure An internal combustion engine with a spark timing control which varies spark timing to maintain a substantially constant peak combustion pressure timing includes a combustion pressure sensor generating a signal contaminated by high frequency noise and further apparatus which tracks the sensor signal only while it is increasing above a previous maximum and generates an output signal whenever it stops tracking to indicate the timing of a new maximum.  Numbers representing the crankshaft rotational positions of the successive signals are stored in a storage element during a crankshaft rotational range in which peak combus-tion pressure is expected.  At the end of the range, the last stored number is used to represent the timing of peak combustion pressure in the spark timing control and the apparatus reset for the next determination.

Abstract: OPTICAL SWITCH     ABSTRACT OF THE DISCLOSURE         An optical switch comprises a first polarization converter; and a second polarization converter which is provided in series with the first polarization converter.      The first and second converters are able to select as emitted light one of two perpendicular polarized light components of incident light having a desired wavelength (.lambda.0) in a polarized state.  The first polari-zation converter converts the incident light having wavelength .lambda. 0 into a polarized light component corre-sponding to one of two points positioned at opposite sides to each other on a Poincaré sphere and obtained by rotating the incident light at +90° or -90° around an axis perpendicular to an axis passing through a point corresponding to the incident light on the Poincaré sphere and the center of the Poincaré sphere.  The second polarization converter converts the polarized light obtained by the first polarization converter into a polarized light corresponding to a point obtained by rotating the two polarized light components at +90° or -90° around an axis passing through the above-mentioned two points on the Poincaré sphere.

Abstract: ABSTRACT     An elevator  has   a converter which changes an A.C. output from an A.C. power source into a D.C. output, an inverter which changes the D.C. output of the converter into an A.C. output, a current detector which detects an output current of the inverter, and an inverter controller which controls the inverter on the basis of the detected current value of the current detector and a command current value, and a hoist motor       driven by the A.C. output of the inverter.          The operation of the inverter  is   stopped when a difference between the detected current value and command current value of the current detector for detecting the output current of the inverter exceeds a preset value.  Accordingly, a current detector for detecting current flowing through the inverter is dispensed with, to realize a simple arrangement and a low cost.

Abstract: ABSTRACT          A method and apparatus for determining the concentration of a predetermined energy absorbing compound in a breath sample even in the presence of other unknown energy absorbing compounds. Infrared energy of three wavelengths are passed through the collected sample.      The first wavelength of infrared energy, 3.95 microns for example, is selected to be insensitive to absorption by both the predetermined energy absorbing compound such as ethanol and the unknown energy absorbing compounds such as acetone and water vapor. The second wavelength of infrared energy, 3.48 microns for example, is selected to be significantly absorbed by ethanol. The third wavelength of infrared energy, 3.39 microns for example, is selected to be significantly absorbed by acetone and water vapor. Operational amplifiers responsive to the first, second and third predetermined wavelengths of energy are utilized to subtract the effect of the absorption by acetone and water vapor so as to generate an electrical output signal which is proportional only to the ethanol concentration.

Granted: 1988-05-24
Abstract: In an apparatus for making plastics carrier bags from a web of tubular film of thermoplastic material, a feeding mechanism intermittently conveys the web by one bag width and a severing mechanism cuts the web into half tubes along an undulating curve. A carriage displaceable in the machine frame transversely to the feeding direction of the web is reciprocated by a drive derived from a first rotating control cam through gearing. A cutting knife pivotable in the carriage about its longitudinal axis passes through the plane of the tube about an axis perpendicular thereto and is so controlled by an oscillating drive derived from a second rotating control cam that its edge is substantially tangential to the undulating curve at the cutting point. A detour assembly retards one of the half-tubes to bring the bag side edge zones into phase and each half tube is formed into bags by a transverse sever-sealing device.

Abstract: Abstract An infusion pump has a removable reservoir including a piston (13) and drive member (12).  The drive member is an internally threaded elongated portion of the piston.  A motor rotates a short drive screw (14), which engages the threads of the drive member to displace the piston in the reservoir (11).  In one embodiment the piston (13) is attached to the drive member (12) by a severable central stem (131) which breaks away to allow engagement with the drive screw. With the stem severed, the piston (13) cannot be retracted, or the reservoir (11) refilled.  Other safety features are shown for locking the displaced piston (13) in the reservoir (11).  A digital metering system has a safety circuit to prevent dangerous failure modes of the rotation sensor and motor drive systems.
