摘要:
The present invention relates to a projecting kaleidoscopic system for viewing kaleidoscopic images on a screen external of a conventional kaleidoscope. In one form, the system includes: (i) a high intensity lamp; (ii) a conventional kaleidoscope positioned in optical alignment with the lamp and including a tube of circular cross section having a longitudinal axis of symmetry, an eye piece at one end and an object box at an opposite end, the box including transparent wall means pointed at the lamp defining a cavity means filled with a multiplicity of loosely assorted pattern producing objects and reflector means within the tube between the eye piece and the transparent wall means wherein the tube, eye piece and object box provide a kaleidoscope that is a separately marketable unit product in and of itself; (iv) drive means mounted in frictional contact with the kaleidoscope for sole support thereof held in such contact by gravity alone wherein the kaleidoscope as a separately marketable unit can be evaluated, the drive means rotating the kaleidoscope about its axis of symmetry at relatively low RPM; (iv) optical lens and focusing means external of the kaleidoscope for optically receiving, enlarging and projecting the kaleidoscopic images appearing at the eye piece; and (v) a rear projection screen means external of the kaleidoscope for viewing the images whereby group viewing is enjoyed.
摘要:
The present invention relates to a system for group viewing of kaleidoscopic images in which such system is a fully-integrated unit that is compact, attractive and of relatively low cost. In preferred form, the system uses a TEE-shaped outer housing in which system elements for the separate functions of cooling, for kaleidoscopically projection, for viewing and for angular pattern driving are accurately and compactly provided. The system elements that provide the functions of cooling, kaleidoscopic projection and viewing are positioned in first and second parallel arms (of circular cross section). While a third transverse arm (of square cross section attached to a flared base supported on a horizontal surface of a desk, table or the like, supports the angular driving elements.

A process and system for treating organic waste materials without venting gaseous emissions to the atmosphere. A fluidized bed including lime particles is operated at a temperature of at least 500.degree. C. by blowing gas having 20%/70% oxygen upwardly through the bed particles at a rate sufficient to fluidize same. A toxic organic waste material is fed into the fluidized bed where the organic waste material reacts with the lime forming CaCO.sub.3. The off gases are filtered and cooled to condense water which is separated. A portion of the calcium carbonate formed during operation of the fluidized bed is replaced with lime particles. The off gases from the fluidized bed after drying are recirculated until the toxic organic waste material in the bed is destroyed.

A secondary electrochemical cell with sodium-sulfur or other molten reactants is provided with a ionically conductive glass electrolyte. The cell is contained within an electrically conductive housing with a first portion at negative potential and a second portion insulated therefrom at positive electrode potential. The glass electrolyte is formed into a plurality of elongated tubes and placed lengthwise within the housing. The positive electrode material, for instance sulfur, is sealed into the glass electrolyte tubes and is provided with an elongated axial current collector. The glass electrolyte tubes are protected by shield tubes or sheets that also define narrow annuli for wicking of the molten negative electrode material.

A heat pump apparatus including a compact arrangement of individual tubular reactors containing hydride-dehydride beds in opposite end sections, each pair of beds in each reactor being operable by sequential and coordinated treatment with a plurality of heat transfer fluids in a plurality of processing stages, and first and second valves located adjacent the reactor end sections with rotatable members having multiple ports and associated portions for separating the hydride beds at each of the end sections into groups and for simultaneously directing a plurality of heat transfer fluids to the different groups. As heat is being generated by a group of beds, others are being regenerated so that heat is continuously available for space heating. As each of the processing stages is completed for a hydride bed or group of beds, each valve member is rotated causing the heat transfer fluid for the heat processing stage to be directed to that bed or group of beds. Each of the end sections are arranged to form a closed perimeter and the valve member may be rotated repeatedly about the perimeter to provide a continuous operation. Both valves are driven by a common motor to provide a coordinated treatment of beds in the same reactors. The heat pump apparatus is particularly suitable for the utilization of thermal energy supplied by solar collectors and concentrators but may be used with any source of heat, including a source of low-grade heat.
摘要:
A secondary, high temperature electrochemical cell especially adapted for lithium alloy negative electrodes, transition metal chalcogenide positive electrodes and alkali metal halide or alkaline earth metal halide electrolyte is disclosed. The cell is held within an elongated cylindrical container in which one of the active materials is filled around the outside surfaces of a plurality of perforate tubular current collectors along the length of the container. Each of the current collector tubes contain a concentric tubular layer of electrically insulative ceramic as an interelectrode separator. The active material of opposite polarity in elongated pin shape is positioned longitudinally within the separator layer. A second electrically conductive tube with perforate walls can be swagged or otherwise bonded to the outer surface of the pin as a current collector and the electrically insulative ceramic layer can be coated or otherwise layered onto the outer surface of this second current collector. Alternatively, the central pin electrode can include an axial core as a current collector.

摘要:
A process for treating organic waste materials without venting gaseous emissions to the atmosphere which includes oxidizing the organic waste materials at an elevated temperature not less than about 500.degree. C. with a gas having an oxygen content in the range of from about 20% to about 70% to produce an oxidation product containing CO.sub.2 gas. The gas is then filtered to remove particulates, and then contacted with an aqueous absorbent solution of alkali metal carbonates or alkanolamines to absorb a portion of the CO.sub.2 gas from the particulate-free oxidation product. The CO.sub.2 absorbent is thereafter separated for further processing. A process and system are also disclosed in which the waste materials are contacted with a reactive medium such as lime and product treatment as described.
