Abstract: SHANK MOUNTING ASSEMBLY FOR SOIL OPENING POINT            Abstract of the Disclosure A shank mounting assembly for a soil opening point permits adjustment of the spacing between a pair of mounting bolts of the assembly for permit-ting attachment of the assembly to farm implement shanks having bolt holes of various spacings.   The assembly includes an elongated adapter having a hidden,  internal cavity to which access is gained only by an elongated slot on the backside of the adapter.  The cavity and slot are so dimensioned that while the bolts may move lengthwise within the slot for positioning adjustment, the enlarged heads of the bolts remain in the cavity and cannot pass through the slot.   By having the cavity accessible only from the back of the adapter and by providing the front face of the adapter with a smooth, contin-uous, soil-engaging surface, the heads of the bolts are protectively unexposed to abrasive contact with the soil during use.

Abstract: Abstract of the Disclosure An improved method and apparatus is provided for estimation of absolute velocity in active or semi-active suspension systems. A controller produces a signal estimate of absolute velocity which can be implemented by a control algorithm to attenuate motion between spaced members, such as in vehicular suspension systems. The controller performs time integration of an accelerometer input signal by an analog integrator means comprising a first-order low-pass filter. A digital feedback or offset means is utilized to stabilize the signal and constrain the constant and relatively low frequency components of the analog integrated signal about an oscillatory voltage range. A digital filter means receives the stable signal and removes selected constant and low frequency components of the signal to produce a signal indicative of absolute velocities for a frequency range of interest further stabilized about a selected mid-range voltage value.

Abstract: A  liver  function  testing  apparatus  measures values  .DELTA.logT1  and .DELTA.logT2,  corresponding to pulse wave signals obtained upon passage through a prescribed optical path in vital tissue, n times when a sensor having first and second light sources and a light receiving element is attached to a testee before injection of a specific dye. A value .alpha.0 is calculated by a two-variable statistical computation as to n .DELTA.logT1 and n .DELTA.logT2 on the basis of an operation expression of logT1 = .alpha.0logT2,  and .DELTA.logT1 and AlogT2 corresponding to pulse wave signals are measured in response to intensity levels of first light and second light passing through the vital tissue from injection to a prescribed  time  on  the  basis  of  decision  outputs representing levels of the first light and the second light from the light sources after the specific dye is injected. A value Cg corresponding to specific dye concentration in blood is operated from .alpha.0, .DELTA.logT1 and .DELTA.logT2. A simulation curve as a function of time changes of the result of the measurement is calculated by the application of the least squares  method,  thereby  to  obtain  a  blood  plasma disappearance rate K and a T-minute retention rate R% of the specific dye on the basis of the simulation curve.

Abstract: A modular joint prosthesis for implantation in a body. A component adapted to be fixed to a long bone having an intramedullary canal includes an elongated male stem having a uniformly tapered outer surface.  In order to accommodate the particular size of long bone to which the component is to be fixed, a properly sized female stem is attached to the male stem before the component is fixed to the long bone.  The female stem is adapted to be received in the intramedullary canal for fixation thereto, and has a uniformly tapered inner surface, the angle of the taper being substantially similar to the angle of taper of the outer surface of the male stem. As a result, the male stem and female stem become locked together when the inner surface of the female stem engages the outer surface of the male stem.  The proper size of female stem is obtained by selecting it from a family of female stems having a graduated sequence of different external dimensions.  Tools are also disclosed for disengaging the male stem from the female stem as well as for disengaging the female stem from the bone.
