Title: Back-side taper wedging drive system
Inventor: GOSS DAVID
IPC: B25B23/10
Filed: 1993-04-20
Granted: 1999-01-12
Abstract: A component for use in a multi-lobular drive system of the type having coaxial, engageable female and male members.          One of the members has threads formed thereon defining a rotational direction.  The female component includes a multi-lobular recess (53) and the male component includes a multi-lobular projection engageable with the recess (53).          The multi-lobular recess (53) and projection each define alternating, interengageable flutes and lobes in which the flutes and lobes on the female member engage the corresponding lobes and flutes of the male member.  The flutes and lobes on one of the members has drive walls and trailing walls which are positioned substantially parallel to the central axis.  The other of the members has drive walls (32,64) and tapered trailing walls (34,66).  Each of the tapered trailing walls (34,66) forms an angle relative to the associated drive walls (32,64).  The tapered trailing wall (34,66) provides a wedging engagement with the corresponding trailing wall of the other member when the male and female members are interengaged.

Abstract: A passive electronic warfare system must deinterleave trains of pulses from a number of radar transmitters. An adaptive parametric channelizer for acquiring and tracking trains of pulses consists of an input channelizer operating under the control of a resource control processor. Each pulse descriptor word (PDW), a set of digitized signal parameters measured by a specialized receiver of radar pulse signals, is temporarily stored in a first-in-first out (FIFO) buffer memory.      PDW data from the FIFO buffer memory is then applied to a set of parameter filter devices. These filters are provided with a range of parameter values, forming windows, by the resource control processor. The filters operate such that when a PDW falls within one of the filter s windows, a match output is asserted and applied to a match list generator which maps asserted matches into a list of filter index numbers. That list is applied to a mapper which transforms filter indices into track buffer indices in order to store a PDW that matches one filter into an associated track buffer of a set of track buffers. The combination of at least one parameter filter linked by the mapper with a track buffer form a track channel.      The match list generator supplies data and event interrupts to the resource control processor which causes the parameter window of any track channel to be modified and force track channels to be merged.

Abstract: A compression-moldable composition comprising an active ingredient, an excipient and an oily or fatty substance having a lower melting point of about 20 to 90°C is compression-molded into uncoated tablets without coating to improve the abrasion resistance. The oily or fatty substance includes a higher fatty acid or a salt thereof, a wax, a fatty acid ester, a hardened oil, a polyalkylene oxide, etc., and the amount thereof is about 0.01 to 10% by weight.

Title: Turn assisting mechanism for a vehicle
Inventor: MIYAMOTO YASUHIKO
IPC: B60S9/12
Filed: 1996-11-15
Granted: 1999-01-26
Abstract: A turn assisting mechanism assists a turning motion of a vehicle,  such as a lawn mowing vehicle,  so that the vehicle may not damage the ground (lawn grass, crops, etc.) when the vehicle makes a U-turn.   The turn assisting mechanism is disposed near a wheel of the vehicle nearest to the center of turning of the vehicle about which the vehicle makes a U-turn.   The turn assisting mechanism stretches out the rod of a hydraulic cylinder  actuator to set a ground contact unit on the ground and lifts up the wheel nearest to the center of turning of the vehicle. When the vehicle makes a U-turn, the hydraulic cylinder actuator sets the ground contact unit on the ground so that the axis of turning of the ground contact unit passes the center  of  turning  of  the  vehicle,  and  lifts  up  the corresponding wheel from the ground.  The vehicle makes a U-turn on the ground contact unit without damaging the ground.

Title: Composite papermaking fabric with paired weft binder yarns
Inventor: JOHNSON DALE B
IPC: D21F1/00
Filed: 1996-12-12
Granted: 2004-09-07
Abstract: A composite forming fabric in which the woven paper and machine side layers are interconnected by pairs of intrinsic Weft binder yarns which interweave with the paper side layer to occupy an unbroken weft path. Each member interweaves sequentially with the warps of the paper side layer and with at least one warp of the machine side layer. Each part of the unbroken weft path is separated from adjacent parts by at least one paper side layer warp yarns. The unbroken weft path is the same, or different, to the weft path of the immediately adjacent paper side layer weft yarns. This arrangement overcomes the paper side layer surface imperfections, which cause an unacceptable level of marking, hitherto associated with the use of intrinsic weft binder yarns in composite fabrics.

Abstract: The present invention relates to a method for producing an electrolytic solution containing a solute of lithium hexafluorophosphate. This method includes a step of (a) reacting lithium fluoride with phosphorus pentafluoride, in a nonaqueous organic solvent that is used for producing a lithium cell's electrolytic solution, thereby to form the lithium hexafluorophosphate dissolved in the solvent. According to this method, both yield and purity of the reaction product are sufficiently high, and the reaction can easily be managed.    According to need, after the step (a), the nonaqueous organic solvent may be replaced with another nonaqueous organic solvent. The present invention further relates to a method for purifying an electrolytic solution used for a lithium cell. This electrolytic solution contains an acid impurity having at least one hydrogen atom in the molecule. This method includes steps of (a) adding at least one hydrogen-free halide selected from chlorides, bromides and iodides, to the electrolytic solution, such that the acid impurity is reacted with the at least one hydrogen-free halide, thereby to form at least one hydrogen halide selected from hydrogen chloride, hydrogen bromide and hydrogen iodide; and (b) purging the at least one hydrogen halide from the electrolytic solution to purify the electrolytic solution. The acid impurity concentration of the electrolytic solution is substantially reduced by this method.
