Abstract: ABSTRACT     A safety valve adapted for placement above a wellhead is disclosed.   The valve has  a housing having coaxial upper and lower vertical housing passages, the diameter of the upper and lower passages being sufficiently large to pass  a  tubing  hanger  with  tubing  for  landing  in  the wellhead.   The valve also has  a control element means disposed between said upper and lower vertical housing passages for preventing or allowing fluid flow through a passage smaller than the lower vertical housing passage and for providing full diametrical access via the upper housing passage to the lower housing passage.    In  a  ball  control  element  embodiment  of  the invention, a rotatable ball is disposed between upper and lower passages and lateral outlets in the housing.  The ball has a removable insert such that in one position of the ball, the insert can be removed to provide full bore access  in  line  with  the  well.   The  housing  may  be incorporated with the tubing head or may be attached to the  top  of  the  tubing  head.   During  insertion  of  or workover of tubing, a blowout preventer may be attached to the top of the valve housing.  The ball may be rotated for closing  off  the  flow  path  from  the  well  below.   A          Christmas  tree  may  be  installed  after  the  blowout preventer is removed.    Diverter  valves  may  be  connected  to  the  lateral outlets.  "T" shaped passages in the ball insert may be aligned with the lateral outlets and the tubing to divert well fluid when desired via the diverter valves.    The  valve  may  be  used  as  a  master  valve  of  a Christmas  tree  with  a  control  valve  attached  to  the lateral outlet.    In  a  gate  control  element  embodiment  of  the invention, a gate valve is provided in which the gate has a removable insert so that in one position of the valve, the  insert can be removed  (or  inserted)  via an upper vertical passage of the valve to provide full-bore access via an attached blowout preventer stack to the well head below.     In another embodiment of the invention a gate valve is provided having at least two vertical passages through the gate.  The first is large enough to provide full-bore access via an upper passage in the housing of the valve. The second is of a smaller diameter to provide vertical communication with tubing disposed in a  lower vertical passage and in an upper vertical passage.     Either of the gate control element embodiments may be used  in  a  lateral  production  tree  where  the  gate  is provided with an "L"  or  "T"  shaped passage in another lateral  portion  of  the  gate  and  lateral  outlets  are provided in the valve housing.     This abstract of the disclosure is neither intended to define the scope of the invention, which is measured by the claims, nor is it intended to limit the invention in any way.

Abstract: BRAKE ACTUATING SYSTEM     ABSTRACT OF THE DISCLOSURE     A brake actuating system for use with a brake assembly having a body, a brake actuator and at least one friction member cooperating with the actuator and the body to brake a brakeable member. The invention provides a system with improved operator "feel" of braking force, and has a first fluid valve receiving pressurized fluid and controlling actuation of the actuator, with a signal input adapted to receive a signal from an operator and to be responsive to extension of the actuator. In this way, a change in brake signal from the operator produces a corresponding change of extension of the actuator which produces a corresponding change in fluid output signal to the actuator. In a first embodiment, a second fluid valve has an input receiving pressurized fluid, an output port adapted to communicate with the actuator fluid input, and a pilot pressure input port communicating with the fluid output of the first valve such that a change in pilot pressure from the first valve as a result of change in brake signal from an operator changes the output from the second valve and also changes the input signal to the brake actuator. In a second embodiment, an alternative first fluid valve only is used and the fluid output means therefrom communicates directly with fluid input means of the actuator. Further alternative embodiments reduce effects of friction in a control cable by providing a direct feedback of actuator force on a control lever, and also permit locking of the lever.

Abstract: Abstract of the Disclosure The fluid flow of the passive hydraulic damper is regulated by command responsive valve so as to in effect disable the damper at those times when it would amplify rather than attenuate movement of the vehicle component whose motion is to be minimized. The command respon-sive valve, along with all other valves of the system, preferably is carried and protected by an accumulator which receives hydraulic fluid from the damper during both extension and retraction thereof.  The control valve is of an improved voice-coil type capable of exceedingly rapid response to command signals directed thereto from an electronic controller receiving input data from motion detecting sensors associ-ated with the vehicle components interconnected by the damper.

In the preferred and illustrated embodiment the free or unpaired electron population of flowing coal is measured by electron magnetic resonance (EMR); the hydrogen nucleii population is measured by nuclear magnetic resonance (NMR).   By calibration utilizing a standard specimen for a given type of coal, a profile for various types of coal can be obtained wherein measurement data is converted into an indication of the heat content typically measured in BTU per pound.  This enables provision of a volumetric flow meter, a flow meter indicating flow in calorie  content.   This device enables  integration  to provide  total heat content  flow.

Abstract: Abstract A color television receiver includes a network for automatically limiting excessive kinescope beam currents developed in response to video signal image information, and a white balance control network for automatically controlling the white level drive (gain) characteristics of the kinescope in response to a white drive reference signal applied to the video signal path during given measuring intervals.  A control signal developed by the beam current limiter network, otherwise applied to the video signal path, is decoupled from the video signal path during the white level measuring intervals to prevent distortion of the white level control function.

Abstract: DEVICE FOR DETECTING RETROGRADE CONDUCTION ABSTRACT      A pacing system analyzer is constructed to provide verification that an implantable cardiac pacer operating in a demand mode will not itself produce tachycardia in a patient because of abnormally long patient retrograde conduction time.  The analyzer when performing the retrograde conduction test provides an intercardiac electrogram, changes the ventricular sense amplifier to asynchronous and samples to determine the maximum amplitude signals over a sampling period to select an amplifier gain factor.  After the gain factor is set additional signal samples are collected, peak-to-peak amplitude is measured and interpolation between data is made to provide waveform "segments" and the best waveform segment to employ for testing for retrograde conduction is selected.  The time periods from pacing to these segments are measured and utilized to determine if retrograde conduction is present.
