Abstract: ABSTRACT OF THE DISCLOSURE      A spinnerette plate having multiple capillaries per counterbore can be effectively used to melt-spin fusion melts of acrylonitrile polyner and water without sticking together of individual filaments.  The spinnerette plate has a resulting density of capillaries of at least 18 per square cent-imeter of plate surface.  The fusion melt is extruded through the spinnerette directly into a steam pressurized solidification zone, the capillaries being spaced so as to prevent premature contact of the extrudate.

Abstract: WELL SAFETY SYSTEM     Abstract of the Disclosure A well safety system for controlling the flow of fluid through  well  conduits.  The  system  includes  a  surface controlled subsurface safety valve made up as part of a tubing  string  extending  from the well surface  to  a subsurface formation within a casing  string.  A packer, installed below the safety valve, forms a fluid tight seal between the tubing and casing to direct fluid from below the  packer  into  the  tubing.  The safety valve contains lateral  passageways  which  allow  communication of fluid from the bore of the safety valve to the annulus between the tubing and casing above the packer. A valve actuator is  releasably  secured  within the upper  portion of the safety valve and forms a fluid tight seal between control fluid pressure in the tubing string above the safety valve and  formation fluid pressure in the tubing string below the safety valve. The safety valve can be locked open when control pressure is increased  above a preselected value and then released.  The safety valve can be unlocked by returning control pressure to another preselected value.          The valve actuator allows liquids to be injected from the surface to below the safety valve to kill the well. The tubing and seals within the valve actuator can he pressure tested  when  the  valve  actuator  is  initially  installed within the safety valve without opening the safety valve.

This is accomplished firstly, by vacuum then venting the vacuum flow and hence separating substantially lighter than density material from the olives, then, passing them through a second region of fluid separation where the olives are separated essentially from materials which are heavier in density than the olives, and then through a mechanical separation chamber or subsystem which separates olives from that foreign material that is sized close to that of the olives. The olives are then conveyed to a collection region or bin from where they are ready for removal by conventional means to a processing plant where the olives are processed into olive oil.

Abstract: ABSTRACT            "Method and Apparatus for Detecting Air in Fuel"     This disclosure relates to detection of air in the fuel supply system of an internal combustion engine of the character wherein the fuel rate supplied to the engine is controlled by regulating the feed pressure to a set of fuel injectors. A pressure sensor is connected in the fuel supply system and an engine speed sensor is connected to the engine.  The engine is started, brought to a stable intermediate no-load speed, the throttle is snapped to a wide open position, and the rate of change of fuel pressure with time is sensed during the initial pressure rise from no load pressure to full load pressure.  This measured rate is compared with a reference rate obtained from an engine where no air is present in the fuel system, and the pressure of air is indicated by a comparison of the measured and reference rates.

Abstract: TONER CONTAINER                   Abstract of the Disclosure A toner container includes a displaceable member located within the container and attached to one end of a flexible membrane utilized to seal the container closed. A bellows member also forms part of the container.  Once the container is inserted into the copy machine in a sealed condition, operator initiated pressure upon an outer wall of the container causes the bellows member to collapse and further causes the displaceable member to move downward carrying with it the membrane member.  As the membrane member is thus deflected, the seal of the membrane member to the toner container is broken allow-ing the contents of the container to escape into the copy machine.  A safety mechanism is utilized with the container to prevent accidental operation of the dis-placeable member during shipment or handling.
