Abstract: ABSTRACT OF DISCLOSURE           Method and apparatus for material analysis in which X-rays generated pursuant to incidence of an electron beam on the material are detected by a detector which generates signals representative of X-ray intensity.  A first single channel analyser is connected to receive the signals from the detector and to pass to an associated first counter a count signal whenever the signal applied to the first single channel analyser is representative of an X-ray energy within a relatively narrow range of such energies.  A second single channel analyser is also connected to receive the signals from the detector and to pass to an associated second counter a count signal whenever the signal applied to the second analyser is representative of an X-ray energy falling within a much broader range of such energies than the first-mentioned range.  The first and second counters accumulate the count signals applied thereto. The count in the second counter is compared by a comparator with a pre-established count in a third counter and when the count in the second counter assumes the same value as the count in the third counter the counts in the first and second counters are held.  The so held count in the first counter then itself represents a normalized ratio of X-ray energy within the narrow range to the X-ray energy for the energy spectrum represented by the broad range of energies.  On the basis of this normalized ratio information as to the makeup of the material can be derived.

Abstract: INFINITELY VARIABLE SEAT RECLINER MECHANISM         Abstract of the Disclosure The invention consists of an infinitely variable seat reclining mechanism which is composed of a first arm attached  to  the  seat  cushion  frame  and  a  second  arm attached to the seat back frame.   A pivot pin rigidly secured to the second arm extends to at least one side thereof  on  an  axis  of rotation.   The  first  arm  is rotatably mounted on the pivot pin to be capable of relative rotation with respect to the second arm.  A pair of locking pawls are rotatably mounted on the first arm. The locking pawls are capable of rotation toward and away from one  another  about  separate pivot points and  into contact with a circular friction surface on the second arm.  The circular friction surface on the second arm has its center at the axis of rotation between the first and second  arms.   A  spring  is  included  for  biasing  the locking pawls toward one another.   Each of the locking pawls has a substantially V-shaped groove on one end thereof which is capable of engaging the friction surface on  the second  arm.   The  friction  surface  also  has  a substantially  V-shaped  section  with  an  included  angle equal to the included angle of the grooves in the locking pawls.  The interaction between the grooved surfaces on the locking pawls and on the second arm prevent relative rotation between the first and second arms.  A lever arm is included for moving the locking pawls away from one another against the spring and out of engagement with the friction  surface of  the  second  arm  thereby  allowing relative rotation between the first and second arms.

Abstract: MAGNETIC SAFETY INTERLOCK FOR A FOOD PROCESSOR UTILIZING VERTICALLY ORIENTED, QUADRANT CODED MAGNETS     Inventor:  Allen F. Podell ABSTRACT OF THE DISCLOSURE     Improved safety interlock method and apparatus are provided for a food processor of the type having a base housing enclosing a motor drive, a working bowl which is detachably mountable on the base housing in position for receiving various rotatable food processing tools which are removably installed on a tool drive in the bowl, and a removable cover on the bowl.  Food processors of this type generally include a control system for preventing actuation of the relatively powerful motor drive, so that the food processing tool does not rotate, unless two conditions have been met, namely:          (1)  the bowl is mounted in its operating position on the base housing, and (2)  the cover is held securely in its operating position on the bowl.          The improved safety interlock provided in one embodiment of the invention uses two permanent magnets. One magnet is associated with actuator means and the other magnet is associated with switch means which prevent operation of the motor unless actuated. These two magnets are oriented generally in vertical planes relative to the horizontal top deck of the base housing.  Each magnet is divided or coded into respective polarity quadrants arranged  so that the magnetic polarities of the quadrants of each of these magnets are non-symmetrical with respect to mutually perpendicular axis.  The magnet associated with the switch means is movably mounted within the base housing.  The actuator magnet is external to the base housing, its position relative to the base housing being determined by the position of the bowl on the base housing and also by the position of the cover on the bowl.  The two magnets are arranged so that the control for the motor drive of the food processor can only be magnetically actuated when both the bowl and the cover are mounted securely in their respective predetermined operating positions.

Abstract: SURFACE CONTROLLED SUBSURFACE SAFETY VALVE            Abstract of the Disclosure A surface controlled subsurface safety valve for deep well service.  Communication of control fluid to the subsur-face safety valve is controlled by a pilot valve at a subsur-face location in close proximity to the safety valve.  Respon-siveness of the subsurface safety valve to decrease in control fluid pressure is thereby increased and the safety valve's closure speed is also increased.  The pilot valve controllably communicates pressurized control fluid to open the safety valve and allows control fluid to be displaced into the flow path through the safety valve during valve closure.          Background of the Invention 1.   Field of the Invention This invention relates to surface controlled subsurface safety valves for controlling fluid flow within a well.  The invention also rotates to a pilot valve for communicating control fluid to the safety valve from the well surface. 2.   Prior Art A common limitation of conventional surface controlled subsurface safety valves is the volume of control fluid which must be displaced from the valve's control chamber to permit valve closure.  Preferably,  safety valves are designed to close when control fluid pressure drops below a preselected value.  Thus, damage to the wellhead and/or control system should result in closure of the safety valve at its downhole location.  For conventional safety valves operated by a single control fluid conduit from the well surface, various fluid forces resist valve closures.   These forces include the hydrostatic pressure of fluid in the conduit, inertia of fluid in both the conduit and the control chamber of the safety
