Abstract: Purification of Contaminated Liquid Abstract A liquid containing radioactive ions is purified (decontaminated) by contacting the same with an inorganic ion exchange composition having ion exchange sites which can be occupied by the radioactive ions from the liquid.  The ion exchange composition is a mixture of an ion exchange medium and an additive which is relatively inert to the ion exchange process and which is a sintering aid for the ion exchange medium designed to lower the sintering temperature of the ion exchange composition.  The ion exchange composition may be disposed within a suitable container (e.g., cannister),  e.g., made of 304L stainless steel or Inconel 601 and the ion exchange process may be carried out in such container.  Alternatively, the ion exchange medium can be employed without being previously admixed with the additive.  The additive, if desired, can be admixed at a later stage with the contaminated medium. Thereafter, the mixture may be sintered and disposed of in any desirable manner as by underground burial of the spent mixture within the container.  Also, the container may be placed within a suitably designed furnace for carrying out the ion exchange process, sintering of the ion exchange composition and its safe disposal.  Methods are also described for making a homogeneous mixture of the ion exchange medium and the additive which, for example, have a certain defined density and particle size relationship.

Abstract: IMPROVED LASER CATHODE               ABSTRACT OF THE DISCLOSURE     An improved laser cathode includes a generally hemispherical hollow shell fabricated of material of preselected thermal character.  The shell includes, at its inner surface, a covering layer of material which includes aluminum.  A thermal seal is created between a laser body of low thermal coefficient material and the cathode by one of a number of conventional sealing processes. By substantially matching the thermal coefficient of the shell of the cathode to that of the laser body the overall laser structure is rendered less vulnerable to thermal cycling.

Abstract: ATTRACT OF THE DISCLOSURE    The carbon content of the residue from combustion of agricultural waste products is controlled and the fly ash content of the gaseous exhaust minimized by utilizing a portion of the combustion supporting air to enhance fluidization of the waste products above a fixed bed while being agitated by a rotating sweep arm inducing radially outward movement toward a residue collecting zone from which a sweep arm paddle displaces the residue into a discharge duct.  The waste product feed is conveyed at a uniform weight flow rate to a central location in the combustion chamber above the bed from which of the feed is dropped onto the bed.

Abstract: METHOD AND APPARATUS FOR SHAPING A      PROXIMAL TIBIAL SURFACE                      Abstract The present invention provides a method and apparatus for preparing the proximal surface of a tibia to receive a proximal tibial prosthesis employing a reamer/alignment guide which is used to internally locate the central long axis of the tibia and a plateau planer which cooperatively engages with a guide handle attached to the reamer/alignment guide to accomplish the shaping of the proximal tibial surface. The reamer/alignment guide has a rod portion extending into the interior of the tibial shaft whose central long axis corresponds with the central long axis of the tibia.  The guide handle is concentric with that rod portion such that the plateau planer assumes the proper alignment with respect to the central long axis of the tibia such that the proximal tibial surface is shaped relative to that axis in a simple and accurate manner.

Abstract: ABSTRACT OF THE DISCLOSURE       A portable power tool comprising a housing defining a combustion chamber and a cylindrical chamber having a reciprocating piston therein.  The combustion chamber has an opening defined by a valve seat closable by a poppet valve and serving as an inlet at one side for unburnt gases or vaporized fuel admitted under pres-sure and an outlet at an opposite side for spent gases.          An ignition assembly is provided for igniting unburnt fuel in the combustion chamber which is synchronized with the closure of the poppet valve.  The combustion chamber and the poppet valve are shaped and arranged such that unburnt fuel admitting through one side of the valve seat opening will sweep the spent fuel of a preceding ignition cycle from the combustion chamber out through the other side of the valve seat opening.

Abstract: ABSTRACT OF THE INVENTION      METHOD AND APPARATUS FOR AERATION OF STORED GRAIN           A method and apparatus for the controlled aeration of stored grain is disclosed that provides for aeration of grain when ambient temperature and relative humidity levels are within a specified range of optimum levels. Aeration of grain is initiated when both the current ambient air temperature is within an acceptable range of the recent average air temperature, and the equilibrium moisture content supported by the current air temperature and relative humidity levels is within an acceptable range of the desired grain moisture content.          Long periods between aeration are avoided by progressively widening the range of acceptable current ambient air temperature and equilibrium moisture content levels when less than a predetermined amount of aeration has occurred. The method also provides for the maintenance of a uniform temperature within the stored grain, and assists in avoiding extreme storage temperatures. The apparatus disclosed provides for continuous monitoring of ambient atmospheric conditions, and initiates aeration of stored grain automatically, in accordance with the inventive method, without continuous operator involvement.

Abstract: MEMORY INTERFACE FOR ELECTRONIC DEMAND         REGISTER OF AN ELECTRIC METER            ABSTRACT OF THE DISCLOSURE     An electronic demand register for an electric meter includes a volatile storage for normal processing of data and a non-volatile storage into which data is serially written upon the occurrence of conditions which may threaten the integrity of such data and from which the data is again retrieved when the condition no longer exists.  The data formats for transmission of the data to the non-volatile memory and for receiving it therefrom do not agree with the data formats which the volatile storage must have.  A communications buffer assembles a data package for transmission to the non-volatile memory which has a format which can be suitably serially transmitted to the non-volatile memory and be properly interpreted there due to the manner in which the non-volatile memory recognizes and stores data.  In addition, the communications buffer receives the serial data from the non-volatile memory and, by left shift and selection of only valid portions of the data, assembles data suitable for transmission to the volatile memory.

Abstract: OPTICAL FIBER CONNECTOR AND ARTICLES CONNECTED THEREWITH            Abstract An optical fiber connector capable of producing very low-loss single-mode fiber connections is disclosed. The  connector utilizes two drawn glass capillary cylinders for holding the fiber ends, and a multiplicity, preferably three, cylindrical alignment rods that provide  multi-point support for the cylinders.  At least one, preferably two, of the alignment rods carry a "flat" extending from one end of the rod for a substantial fraction of the length of the rod.  The assembly is held together by appropriate means, e.g., a substantially triangular alignment fixture.  The presence of antiparallel flat-carrying alignment rods permits simple alignment of the two fiber cores, typically by means of rotation of one or both of the capillary cylinders.

Abstract: Abstract of the Disclosure A photoelectric combustion products detector for periodically sampling the ambient air includes sampling means capacitively coupled to an AC source, so that the coupling capacitor produces at the sampling means a source current 90° out of phase with the AC source voltage, which is rectified to provide a supply volt-age.  Sampling is controlled by a NAND gate having at its inputs a varying threshold level which is propor-tional to and in phase with the supply voltage.  A ramp signal generator connected to one gate input terminal enables the gate when the ramp signal exceeds the vary-ing threshold level.  The other input terminal of the gate is connected to a timing circuit comprising a Zener diode, a capacitor and a discharge resistor which produces a short trigger pulse at or near each positive zero crossing of the AC source voltage, the coincidence of a trigger pulse with an enabling period causing the gate to actuate the sampling means.
