Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for adjusting the damping force of a hydraulic telescopic shock absorber to provide a greater increase of the damping force at increasing piston speeds.  The apparatus comprises a piston which separates two cylinder chambers with a system of passages in the piston for passage of the damping medium from one chamber to another.          This system is closed when the shock absorber is in the rest position by a spring loaded valve having an adjustment member.  The passages closed by the valve each de bouch separately on the valve and have separate inlets which can be closed successively by an adjusting member.

Granted: 1982-05-11
Abstract: ABSTRACT         A speech analysis and synthesis apparatus is described in which high stability is achieved even when the normalized predictor residual power falls below the limited accuracy of the apparatus as with voiced speech.  The normalized residual power obtained on the analysis side is monitored and when it falls below a predetermined valve, the number of stages of a synthesis filter is controlled in correspondence with the order of the linear predictor coefficient obtained in the analysis side.          Also, the normalized residual power is obtained from the linear predictor coefficient on the synthesis side and is used to excite the synthesis filter thereby to prevent speech quality from being degraded due to quantization errors and transmission errors.

Abstract: ELECTRICAL CONNECTION WITH RESILIENTLY      DEFORMABLE SUPPORT MEANS     ABSTRACT OF THE DISCLOSURE      An electrical connector for making or breaking an electrical connection with, for example, another such rela-tively movable electrical connector, includes an electrically conductive contact supported by a resilient deformable support so that a force applied to the electrical contact causes deflection of the support and applies a biasing force to the conductive contact to resist movement in response to the applied force.  Thus, the two contacts are pressed against each other to complete the electrical connection and the electrical connector provides a complete electrical circuit without the need for interlocking.

Abstract: CLOSED LOOP SENSOR CONDITION DETECTOR              ABSTRACT OF THE DISCLOSURE         An electronic control unit for regulating the air/fuel  ratio  of  an  internal  combustion  engine  is disclosed.  The electronic control unit has an open loop calibration  for  regulating  air/fuel  ratio  that  is corrected with a closed loop signal developed by an inte-gral controller. The integral controller bases the closed loop correction signal on a signal from an exhaust gas composition sensor located in the engine exhaust manifold. Various conditions of the system are sensed by a closed loop sensor condition detector to provide information on whether the sensor is up to operating temperature and is operative. If the exhaust gas sensor is functioning and the operating system parameters indicate the system opera-tion should move  to closed loop control,  the loop is closed by the condition detector.  Included in the condi-tion detector circuit is a timer whose cycle is RPM depen-dent.  The timer will time out if the sensor has not indi-cated an operational capability in one timing cycle or a set number of RPM counts and will generate a signal indi-cating  a  sensor  failure.  After  closing  the loop,  the detector circuit will check for a sensor transition on a periodic basis related to the authority of the integral controller and provide a signal to open the closed loop if the transition does not occur. A rich burst generator is provided to perturbate the loop periodically to produce a rich  transition of  the  sensor  if  it  is operable.   A latching  failure  indicator  circuit  is  additionally included in the system to energize a visual indicator and alert an operator if the failure condition occurs.

Abstract: Abstract of the Disclosure The specification discloses a method for producing ethanol in a high concentration, e.g. 200 mg/ml, by using an immobilized microorganism which comprises the steps of contacting the immobilized cells of a microorganism of the genera of Saccharomyces or Zymomonas with a culture broth containing a fermentative sugar and other nutrients necessary for the growth of the microorganism; microbiologically converting the sugar into ethanol; adding an additional fresh culture broth containing the sugar to the conversion reaction system; if required, intermittently or continuously repeating the addition of a broth containing the sugar; and then separating the broth containing ethanol produced.  This method avoids the disad-vantage of prior art processes, such as low concentrations of ethanol and immobilization of the microorganism by high concentrations of the fermentative sugar.

Abstract: TITLE                 TRAILER UNDERCARRIAGE FAIRINGS                          INVENTOR Bradley Paul MARTIN                        ABSTRACT     An aerodynamic fairing for placement under the undercarriage of a tractor or a trailer or a straight truck as disclosed.          The fairing is placed in front of the transverse axle that carries road running wheels and preferably in advance of each of such axles.  The fairing assists in air diversion and in the streamlining of air passing by such axle.   Air turbulence is reduced and the drag on the vehicle, tractor or trailer is also reduced.  Greater fuel efficiency is achieved.  Also, when the vehicle travels over wet roads or snow covered roads, the normally created air turbulance caused by the road wheels and the traverse axle, that collectively gather up the water or snow from the road ie. is lodged in the tire threads and then spun off into the air as a wake of accumulated water or snow, as the case might be, inhibits visibility to overcoming and oncoming traffic so significantly that in severe cases the visibility is nil.          The fairings of the invention reduce the air turbulence and hence the extent of the wake and improve the visibility through whatever wake there is remaining to almost normal driving conditions (ie. as if there is no wetness or snow on the road).

Abstract: Case No. 800232 BLOOD COLLECTION SYRINGE Christen C. Rattenborg ABSTRACT OF THE DISCLOSURE A syringe for collecting a blood sample includes a cylindrical housing having a hollow needle at one end. A plunger slidably mounted within the housing defines a chamber within which blood collected by the needle is received. A hydrophilic bypass element disposed between the rim of the plunger and the inside surface of the housing forms a passage-way through which air is exhausted as blood enters the chamber under arterial pressure. The passageway is automatically closed to prevent leakage from the chamber when the chamber becomes filled with blood and the bypass element is wetted. An alternate embodiment wherein the hydrophilic bypass element is in the form of an annular sleeve extending around the rim of the plunger is shown.
