Abstract: A fastening system device having dimensions of very small magnitudes for attaching a mesh prosthesis or tissue to body tissue. The device has a shaft member which has a continuous outer peripheral surface and so constructed such that the outer surface is a continuous surface and has a continuous curved cross-section where the center of curvature is in the radial direction of the longitudinal axis; the shaft has sufficient columnar resistance to bending to permit the shaft member to penetrate body tissue. A head member extends radially from the shaft member at a second end and is so dimensioned and proportioned to form a bearing surface for bearing against the mesh prosthesis. A resiliently collapsible anchor member is integrally fixed to the first end of the shaft and separately forms a conical distal tip. The anchor member extends proximately and is contained at least in part in the conical surface of the conical tip and projects angularly with respect to the outer continuous peripheral surface and is bounded in radial collapsibility by the continuous outer peripheral surface of the shaft.

Abstract: A preload mechanism for use in a rotary control valve is disclosed. The preload mechanism mechanically interlocks input and output members of the control valve to inhibit relative rotation therebetween when steering torque applied to the input member is below a predetermined preload level. The preload mechanism includes a tension spring ring having at least one pair of elongated slots. Pins secured to each of the input and output members project through and are retained in the slots in an over-constrained manner whereby the preload force is bi-directionally exerted on both of the pins.

Abstract: The present invention is directed to providing an improved control valve having input and return flow passages that are hydraulically-balanced by virtue of each having a similar flow configuration for fluid flow therethrough. The input and return flow passages are formed to define input and return flow control orifices, respectively, configured for minimizing the possibility of the jet flow issuing from either input or return flow control orifices from impinging upon a surface in juxtaposition to the flow control orifice itself. Thus, the possibility of partial "flow back" into the flow control orifice is eliminated which, in turn, also prevents any significant reduction in the flow control orifice area.

Abstract: The present invention is directed to a vehicular power steering system having an "open-center" control valve that has substantially zero hydraulic flow gain at zero input deflection angle and yet has minimal control orifice area. Improved valving arrangement is desirable in that it leads to rapid restoration of hydraulic flow gain at relatively small input deflection angles. The improved valving arrangement includes small transverse leakage slots formed in a valve spool that are positioned in parallel with either input or return flow distribution slots. The leakage slots are configured to form parasitic flow orifices which fluidically interconnect the output slots formed in the valve sleeve and which communicate with the fluid chambers formed on opposite sides of the piston in the power cylinder. Accordingly, a selectively variable leakage path is provided across the power cylinder.

Abstract: A reaction type control valve, primarily intended for controlling a power assisted steering system, comprising a hydraulic interface having variable effective reaction areas, the extent of which is determined by selected functions of values of torque applied thereto. Differential hydraulic fluid pressure is generated by the valve, which differential hydraulic fluid pressure is proportional to the applied torque and inversely proportional to any particular effective reaction area. Hydraulic fluid is induced to flow through a hydraulic interface between first and second valve members wherein primary and secondary sets of input and return orifices are selectively utilized to define the effective reaction areas as a function of the input torque. The primary and secondary sets of input and return orifices are located at selected radii. The selected radii locating the primary sets of input and return orifices comprise first and second radii, respectively, wherein the first radii are smaller in value than the second radii. The selected radii locating the secondary sets of input and return orifices comprises third and fourth radii, respectively, wherein the third radii are smaller in value than the fourth radii. And, the difference between the second radii and the first radii is greater than the difference between the fourth radii and the third radii.

Abstract: The present invention is directed to a hydro-mechanical or electro-hydro-mechanical control system utilized for positioning a mechanical device. The control system incorporates a control valve for selectively controlling the flow of hydraulic fluid to input ports of a power output transducer. The power output transducer is then utilized to position a mechanical device. The control system is a closed loop circuit adapted to supply hydraulic fluid at a desired supply pressure to the control valve. The supply pressure is varied in relation to the absolute value of the pressure differential or load pressure exerted across the input ports of the power output transducer. A pressure regulating apparatus is provided for selectively regulating the supply pressure to a value that is nominally equal to the absolute value of the load pressure summed with a preselected supplemental pressure value across the regulating apparatus. As such, any pressure drop across the control valve is maintained at a nominally constant value which is nominally equal to the difference between the supply pressure and the load pressure.

Abstract: A surgical fastener system for fixing a mesh prosthesis to body tissue for the laparoscopic repair of inguinal herniation or for fixing body tissue to body tissue. A unidirectional dart fastener is utilized where the dart fastener is composed of a shaft member and an anchor member extending angularly from the tip of the shaft. The anchor member is resiliently collapsable radially to the shaft and biased in an open position which permits the dart to be captively held unidirectionally in the body fascia. A dart fixation tool carries the dart fastener in a cartridge which has a series of cylindrical chambers spaced radially adjacent to the periphery of the cartridge and the dart is ejected into the body tissue by a setting rod which is responsive to an external force to thrust the rod through the chamber. The setting rod is thereafter retracted from the chamber and the cartridge is rotated by the surgeon to bring another succeeding chamber into alignment with the setting rod.

Abstract: A tachometer particularly adapted for operation as a rotational velocity feedback transducer is provided. First and second proximity detectors are used to monitor orthogonal positions of an irregular surface portion of a rotating shaft and provide x and y signals that are substantially in quadrature. The x and y signals are differentiated with respect to time to provide differential signals that are representative of dx/dt and dy/dt, respectively. Signals representative of products x dy/dt and y dx/dt are generated from the x signal and the differential signal dy/dt, and the y signal and the differential signal dx/dt, respectively. A signal representative of algebraic sum x dy/dt--y dx/dt is generated from the signals representative of products x dy/dt and y dx/dt. A signal representative of quotient of (x dy/dt-y dx/dt) divided by the displacement r.sup.2 of the irregular surface portion is generated from the signal representative of algebraic sum (x dy/dt-y dx/dt) which signal is representative of the rotational velocity of the rotating shaft.
