Title: Sewing machine needle and method for manufacturing same
Inventor: TAKEI YOSHITSUGU
IPC: A61P31/04
Filed: 1992-05-11
Granted: 1996-09-17
Abstract: A sewing machine needle is manufactured without producing any burrs on a blade by subjecting the whole blade to die pressing.  A needle blank (10) is subject to double swaging, resulting in it being formed with blade sections (14, 16). Then, the needle blank is formed with an elongated portion (22) for subsequently forming a clearance-above-eye above a needle eye. The die pressing permits both side surfaces of a long groove (28) to be spread so as to be spaced from each other at a predetermined angle, and permits the clearance-above-eye (40) and eye portion (30) to be formed. The sewing machine needle thus formed exhibits sufficient rigidity and proves an increased space between the blade and a sewing thread, resulting in a sewing operation being carried out stably and at an increased speed.

Abstract: A receiver dryer for an automobile air conditioning system embodies a cylindrical housing having a spin-closed top end; an inlet tube and an outlet tube inserted in holes drilled in the top end of the housing and both extending through the housing to their respective predetermined positions; and an axially inserted desiccant bag and thermoplastic perforate filter.  The outlet tube extends through a hole in the filter to a predetermined position from the bottom end of the housing, and a retainer clip holds the filter at a set position in the housing while the bottom end of the housing is spin-closed.  Spin closing the bottom end creates a thermal gradient in the wall of the housing such that the thermoplastic perforate filter is thermally bonded at its edge to irregularities of the inner surface of the housing thereby forming a barrier to any particulates which might otherwise have passed by the filter.

Title: Feed products and method for production of same
Inventor: JOHNSEN FREDDY
IPC: A23K1/16
Filed: 1993-07-13
Granted: 1998-09-15
Abstract: The invention provides a new feed product, especially a fish feed product in the form of pellets or particles, with high fat content and superior physical properties.            The product is made immersing feed pellets in a first hot oil bath with a temperature higher than 100°C to secure drying of and simultaneous fat absorbtion.            This treatment is followed by a cooling in a warm oil bath kept at a temperature of 40 - 60°C. This completes the fat absorbtion and results in a dry product consisting of hard and smooth particles with high fat content, which are free flowing and do not agglomerate.

Title: Subcarrier communication system
Inventor: CHADWICK DAVID J
IPC: H04H20/34
Filed: 1995-02-01
Granted: 2004-01-20
Abstract: A communication system (100) is provided for transmitting data to mobile receivers utilizing a subcarrier within a commercial FM channel of a radio station (55). The data transmitted is first encoded in encoder (112), utilizing a forward error correction code.      The sequence of the encoded data is altered in interleaver (116), subdivided into a plurality of subframes, in framing and synchronization circuit (120), which also adds channel state bits to each subframe. The framed data is modulated onto the subcarrier in the differential quadrature phased shift keying modulator (130), the output of which is coupled to the FM modulator (52) of radio station transmitter (50). The transmitted radio frequency signals may be received by a vehicle antenna (12) for coupling to the vehicle's FM receiver (80). The modulated subcarrier is recovered from the FM demodulator (84) of the receiver (80), the modulated subcarrier being demodulated to recover the encoded digital data therefrom.        The channel state bits included with the data are extracted from the digital data and utilized to form a data reliability factor for each bit of the encoded data.      The data reliability factors thus obtained are associated with each bit of the data in a deinterleaver (360).      Deinterleaver (360) provides each data bit in proper sequence, with its associated data reliability factor to a decoder (370). The decoded digital data is provided to a vehicle traffic computer (90) for processing and presentation of traffic information to a user on a display (92).

Abstract: The topology of parallel axis gears, such as spur and helical gears is modified to produce quieter and more smoothly operating gear sets with more uniform load distribution. A finite element analysis of the gear in its operating mode is made to produce a plot of radial and tangential deflections of the pinion and gear tooth surfaces which will occur when the gears are loaded during operation. The resultant plot is then inverted to produce a plot, or see of coordinates, which will define the path of travel of the gear tooth grinding wheel, which path is a mirror image of the plot of the finite element analysis. The resulting gears, when subjected to operating loads, will thus be deflected tangentially and radially to their optimum operating, or theoretical true involute, positions so as to produce quieter, smoother, and more evenly loaded gear trains.

Abstract: In aluminum smelting by electrolysis, a double salt of KAlSO4, as a feedstock, is heated with a eutectic electrolyte, such as K2SO4, at 800°C for twenty minutes to produce an out-gas of SO3 and a liquid electrolyte of K2SO4 with fine-particles of A12O3 in suspension having a mean size of six to eight microns.  This is pumped into a cell with an electrolyte comprised of K2SO4 with fine-particles of Al2O3 in suspension, an anode and a porous cathode of open-cell ceramic foam material.  The cell is maintained at 750°C and four volts of electricity applied between the anode and the cathode causes oxygen to bubble at the anode and liquid aluminum to form in the porous cathode.  A channel within the porous cathode, and the porous cathode itself, are deep enough within the cell electrolyte that the pressure head of electrolyte is enough to overcome the difference in density between the molten aluminum and the electrolyte to pump molten aluminum from the channel out of the side of the cell.  The electrolyte K2SO4 is periodically bled-off to control a build-up of the material as aluminum is produced from the double salt of KAlSO4.
