Abstract: ABSTRACT       Device for Connecting a Tailpipe to an Exhaust Pipe A connecting device connects a tailpipe to an exhaust pipe of an internal combustion engine for a vehicle.  The tailpipe includes a smaller diameter section and a larger diameter section, and the free end of the exhaust pipe is received by the larger diameter section of the tailpipe.  An annular space separates the larger diameter section of the tailpipe and the free end of the exhaust pipe.  Screw threads are formed on the free end of the exhaust pipe.  A connecting spring is configures as conical helical spring, the larger diameter end of which is fixed to the tailpipe.  The other end of the spring has coils configured as screw threads which screwed onto the screw threads which are formed on the free end of the exhaust pipe. The spring is relatively soft in a direction parallel to an axis of the tailpipe, and is relatively stiff in a direction transverse to an axis of the tailpipe.  The spring absorbs vibrations of the engine and centers the pipes with respect to each other.

Title: Method and apparatus for determining the heating value of a gaseous fuel
Inventor: ANSELMO FINI
IPC: G01N30/30
Filed: 1991-01-14
Abstract: A method and apparatus are described for determining the heating value of natural gas. The apparatus utilizes a chromatographic column, and a first sensor connected by a length of tubing in series with a second sensor, all of which are placed in a thermally isolated chamber, in order to keep the temperature constant. The method operates on a principle of comparison of the mass of natural gas, which contains hydrocarbons, higher hydrocarbons, and noncombustibles, with the mass of pure methane. In determining the heating value of the natural gas, the amount of noncombustibles present in the natural gas is determined, and this amount is subtracted from the mass of the natural gas to yield the mass of the hydrocarbon content. From the mass of the hydrocarbon content, the amount of higher hydrocarbons in the natural gas is determined.  Once this is complete, the amount of methane present in the natural gas is calculated and that value along with the value representative of the higher hydrocarbon content are used to calculate the heating value of the natural gas.

Abstract: A vacuum cleaner with the noise greatly reduced is disclosed.   The vacuum cleaner includes a blower assembly which comprises: a vibration absorbing means for absorbing the vibrations occurring due to the high speed revolutions of electric blower 1; a noise shielding means for shielding the noise so as for the noise from the electric blower not to be propagated to the outside; a flow path changing means for curving and extending the flow path by banding the flow path of the air after passing through the electric blower; and a noise absorbing means for suppressing the noise by absorbing the noise propagated through the flow path. The vacuum cleaner of the present invention further includes blower assembly receiving section 41, which finally shields and absorbs the noise. Further, a vibration absorbing means is installed on the contact portion between the vacuum cleaner main body and the blower assembly, and air suction hole 48 is farmed on partition wall 44 which separates the dust collecting room and the blower receiving room from each other, so that the noise generated by the electric blower should be shielded without giving any increased resistance to the flow of air.

The chambers and passages neces-sary for separating cellular components from a sample such as whole blood in-clude a measuring chamber (40), an overflow chamber (44), a separation chamber (60), and a reagent chamber (80), The measuring chamber (40) and overflow chamber (44) have capillary di-mensions. so that an initial volume of whole blood partitions therebetween, with the measuring chamber filling first to provide a preselected volume. The se-paration chamber (60) is located radially outward from both the measuring cham-ber (40) and the reagent chamber (80) so that spinning of the rotor causes both the reagent and the measured blood vo-lume to flow outward into the separation chamber (60). A collection chamber (90) is formed to receive the plasma from the separation chamber (60). Further spinning of rotor causes the plasma to flow radially outward into a plurality of test wells (92) formed around the periphery of the collec-tion chamber (90). Testing of the separated plasma volumes may be performed without removing the plasma from the rotor.

Title: Method and apparatus for direction related interpolation
Inventor: BOIE WERNER
IPC: H04N5/44
Filed: 1993-03-01
Abstract: For Proscan conversion adjacent fields cannot be used to inter-polate moving objects because motion blur will be introduced then. The most simple solution is to insert the average of the two adjacent lines for each missing line. A technique superior to vertical averaging represents the DIAG3 algorithm, where ac-cording to the found minimum gradient the orientation of the in-terpolation filter is chosen. But in case of high diagonal frequencies interpolation errors will occur.      Therefore it is tested if the reconstructed pixel value exceeds or falls below the pixel values in the two adjacent lines of the input signal. If this happens, instead of one of the detected diagonal directions the vertical direction is taken, i.e. a ver-tical averaging is carried out.

Title: Liver enriched transcription factor
Inventor: SLADEK FRANCES M
IPC: C07K16/00
Filed: 1991-12-23
Abstract: HNF-4 (hepatocyte nuclear factor 4) is a protein enriched in liver extracts that binds to sites required for the transcription of the transthyretin (TTR) and apolipoprotein CIII (apoCIII) genes (Costa et al., 1989; Costa et al., 1990; Leff et al., 1989). We have purified HNF-4 protein (54 kD) and isolated a cDNA clone encoding the protein. HNF-4 is a member of the steroid hor-mone receptor superfamily with an unusal amino acid in the conserved "knuckle"  of the first zinc finger (DGCKG). This and the fact that HNF-4 does not bind significantly to estrogen, thyroid hormone or glucocorticoid response elements indicate that HNF-4 may represent a new subfamily. HNF-4 binds to its recognition site as a dimer and activates transcription in a sequence-specific fashion in nonhepatic (HeLa) cells. HNF-4 mRNA is present in kidney and intestine as well as liver but is absent in other tissues. DNA binding data suggest that HNF-4 could be identical to liver Factor A (LF-Al), a factor previously shown to regulate the transcription of the .alpha.-1 antitrypsin, apolipoprotein Al and pyruvate kinase genes.
