Abstract: Abstract of the Disclosure A method of reclaiming thermoplastic material from municipal waste wherein the thermoplastic material is separated from the municipal waste and is decimated into fragments which are of a size to pass through a screen of a predetermined mesh, for example a mesh with one-half inch openings.  Similarly, fallen leaves are kept segregated from other municipal waste and are shredded or similarly decimated so that they may pass through a screen having a pre-determined mesh, for example of a mesh comparable to that through which the plastic must pass.  The fragments of thermoplastic material and the leaf fragments are blended so as to be  thoroughly intermixed, subjected to sufficient heat and pressure so that the thermoplastic material may coat and bond to the surfaces of the leaf fragments and form a unitary mass of leaf fragments and plastic material.  The consolidated mass of leaves bonded by the thermoplastic material is then permitted to set and cure so as to be formed into any desired shape.  A preferred shape is in the form of particle boards of standard length and width for use in construction and the like.

Abstract: DOUBLE CUP CONTAINER AND METHOD OF FORMING SAME  ABSTRACT OF THE DISCLOSURE           A container which is formed of two cup-shaped members, one member being a bottom and the other member being a top.  The two members have end walls which are configurated to resist deformation under high internal pressures as may occur in beverage containers.  The mem-bers have cylindrical bodies and an end portion of one of the bodies is radially inwardly offset so as to be receiv-able in the other of the members.  Prior to assembly, an adhesive, preferably in powder form, is applied to the offset end portion and the two halves are joined together by first heating the larger diameter end portion to facilitate assembly, then telescoping the end portions with the inner end portion then being heated so as both tightly to fit within the outer end portion and to fuse the adhesive.

Abstract: ABSTRACT OF THE DISCLOSURE        A gas discharge tube is provided for use in a detector of the type capable of identifying ionizable species in a carrier gas.  The tube contains an inert gas at reduced pressure and the gas is excited by an external circuit including a coil about the tube.  The circuit generates a radio frequency which excites the gas and emits ultraviolet radiation.  This radiation passes through a transversely located window at the end of the tube for ionizing the species in a chamber.  The radiation is at a level of radiative flux which is substantially uniform over the entire area of the window.  Electrodes are also described for use in association with the chamber to sense ionization.          These electrodes form part of a sensing circuit.

Abstract: ABSTRACT              ELECTROMAGNETIC FUEL INJECTOR       A high flow rate electromagnetic injector valve with a rapid response time is disclosed for utilization in a single point fuel injection system. Centrally bored end caps are fixed at the front and rear ends of a tubular injector body and a coil wound on a bobbin is disposed inside the body chamber between the end caps.  The front end  cap  receives  within  its  bore  a  valve  assembly including a valve housing and a needle valve with attached armature  reciprocally movable against  a valve seat to obturate a metering  orifice in the valve housing.   The valve housing contains fuel  inlets for  the pressurized entry of fuel into the injector and the needle valve is ported to provide fluid communication to the armature to relieve pressure build-up.   The rear end cap threadedly mounts within its bore a core member acting as a stator which extends through a central bobbin bore to form a controllable air gap adjacent the armature, and further contains internally an adjustment screw and ball member. The ball member and adjustment screw cooperate with a recessed closure spring positioned substantially within the armature to controllably bias the needle valve against the valve seat.   Because of its recessed position, the force of the closure spring is applied substantially along the central axis of the injector valve and the ball member prevents tortional windup forces from being generated by the spring.  O-ring seals for the bobbin bore are provided in compression between recesses  in the bobbin and the slower contracting material of the front end cap and core member to produce extended cold temperature operation.

Abstract: METHOD FOR MONITORING IRRADIATED   FUEL USING CERENKOV RADIATION               ABSTRACT OF THE DISCLOSURE    A method is provided for monitoring irradiated nuclear fuel inventories located in a water-filled storage pond where-in the intensity of the Cerenkov radiation emitted from the water in the vicinity of the nuclear fuel is measured.  This intensity is then compared with the expected intensity for nuclear fuel having a corresponding degree of irradiation exposure and time period after removal from a reactor core.          Where the nuclear fuel inventory is located in an assembly having fuel pins or rods with intervening voids, the Cerenkov light intensity measurement is taken at selected bright spots corresponding to the water-filled interstices of the assembly in the water storage, the water-filled interstices acting as Cerenkov light channels so as to reduce cross-talk.  On-line digital analysis of an analog video signal is possible, or video tapes may be used for later mearurement using a video editor and an electrometer.  Direct measurement of the Cerenkov radiation intensity also is possible using spot photometers pointed at the assembly.
