Abstract: ABSTRACT:     A package for electrical and/or electronic com-ponents such as capacitors and resistors comprises a strip-shaped carrier formed with apertures which are uni-formly spaced along the carrier for accommodating the components.  The carrier is also formed with a row or rows of feed perforations, by means of which the package can be feed along in a feed machine   The components are held in the apertures by two tapes which extend longitu-dinally of the carrier on one side thereof and which each have an adhesive layer on the side facing the carrier.          The tapes are spaced from each other and extend over por-tions of each aperture so that the aperture is only par-tially covered by the tapes.  This leaves part of the component in the aperture exposed so that an ejector can engage the component to press it out of the aperture.  In certain circumstances a single tape will suffice.

Abstract: ELECTROMECHANICAL DEVICE              ABSTRACT OF THE DISCLOSURE          A pump such as a vehicle air conditioner compressor has a compressor shaft, a continuously engine-driven flywheel and means such as an electromagnetic clutch for selectively coup-ling the flywheel to the shaft to operate the pump.  The fly-wheel also provides a permanent magnet field which field rot ates with the flywheel and induces in the windings of a rela-tively stationary annular stator assembly an electric voltage in response to the rotating magnetic field.  The pump shaft, annular clutch actuating coil, annular stator assembly and permanent magnet flywheel are all generally concentrically disposed and in the order stated.   The flywheel is driven any time that the engine is running thereby inducing a volt-age in the stator windings and that flywheel also drives the exemplary compressor when the clutch is actuated.

Abstract: CIRCUIT FOR DETECTING LOSS OF SUPPLY VOLTAGE            ABSTRACT OF THE DISCLOSURE       A circuit (10) is provided for use in a telecommuni-cations integrated circuit which has a memory for storing a telephone number.  The circuit (10) essentially comprises a latch having differential nodes (22, 28).  The circuit (10) serves to detect when the supply voltage provided between the supply terminals (12, 14) drops to a level which causes loss of the data stored in the integrated circuit memory.  An output signal (PUC) is driven to a low state upon detection of loss of power.          For a slow return of supply power the nodes (22, 28) are respectively pulled to low and high states by current leakage through diodes (30, 36, 38) connected to the power terminals (12,14).  For a rapid supply voltage transition the latch node (28) is pulled high by capacitive coupling through a diode (30).  This serves to set the latch in the condition where the output node (22) is at a low state to indicate loss of power.  After generation of the PUC signal in the low state, external circuitry provides a reset signal (.PHI.S) which serves to reset the latch of circuit (10) to indicate that the supply voltage has been provided continuously since receipt of the last reset command by the circuit (10).     .

Abstract: Abstract of the Disclosure A system of ionized oxygen allotrope gas water purification and method and apparatus therefor which uses as the water treating agent ionized oxygen allotrope gas, as distinguished from common chemical treatment substances, in which the raw material for practicing the invention is ambient air, and specifically its atmospheric oxygen content.          In accordance with the invention an apparatus is provided which has a gas flow path having an oxygen allotrope forming site that includes a magnetic flux field within the flow path characterized by spaced and interacting rows of alter-nately polar, rod magnet type, flux field  in flux attract-ing relation longitudinally and crosswise of the rows, and an elongate oxygen photolysis lamp operating within the flow path at the site and enveloping the flux with ultraviolet wave length ionizing electrowatt radiant energy emissions.          Ambient atmospheric air is passed in a continuous gas flow through the flow path, and the atmospheric oxygen contained therein at the oxygen allotrope forming site concurrently becomes energy transformed and ionized to form stable oxygen allotrope ions that have high energy and magnetic property levels.  The gas flow including the energy charged oxygen allotrope ions is conveyed to and is interspersed in the water to be treated in a continuous flow application whereby the oxygen allotrope ions are dispersed by natural attraction to the water molecules and thence to contaminant substances that are oxidized by the highly active individual oxygen allotrope ions.

Title: Production of elemental silicon from impure silane  feed
Inventor: WALKER JOE M
IPC: B01D53/02
Filed: 1982-08-24
Granted: 1985-10-22
Abstract: Abstract Elemental silicon is produced by a process and apparatus wherein relatively impure silane (SiH4) is purified in the gaseous state, while mixed with an inert carrier gas, to an impurity content no higher than that of "electronic grade" silicon, then is thermally decomposed to form elemental silicon of electronic grade purity, without need for purifica-tion of the elemental silicon itself.  The purifi-cation is carried out by injecting the impure silane gas as a series of timed, spaced pulses into a carrier gas stream which transports the silane pulses to a gas chromatographic column, through which the pulses flow in sequence.  The components of each pulse are differentially retarded by the packing so that they move through the column at different rates, as a result of which they exit at different but precisely spaced time intervals in relation to pulse input time. The emergence from the column of the silane "peak" or portion of the respective pulse is detected individually or is timed from the pulse input.  When detected or timed, the eluent silane peak and admixed carrier gas are valved to a receiver separately from the other components, which exit before and after that peak.      The silane gas fraction of the peak is then thermally decomposed, to form elemental silicon which is of electronic purity, or it may be collected and pressurized before thermal decomposition. The admixed carrier gas is not decomposed, remains a gas, and thereby is separated from the silicon. Depending on the extent to which the gas purification is carried, the product silicon may have a measured resistivity of about 1500 ohms cm. or better, and can be used in fabrication of solar cells or semiconductor devices without further purification.

Title: Flow line bundle and method of towing same
Inventor: MORTON ARTHUR W
IPC: F16L1/16
Filed: 1982-10-01
Granted: 1984-05-15
Abstract: Abstract A flow line bundle assembly includes a plurality of con-duits disposed within a tubular covering member.  The tubular covering member is sealed at its ends before being placed in a body of water, so that the flow line bundle has a slight positive buoyancy when submerged in the body of water.  Weights are then added to the flow line bundle to cause it to have a neutral buoyancy at a position slightly above a floor of the body of water.  The flow line bundle is then towed from its point of construction, through the body of water, to the loca-tion where it is to be installed.  During a first method of towing, if an obstacle located above the ocean floor is approached, a trailing tug increases a restraining force applied to the flow line bundle so as to lift it above the obstacle as the flow line bundle  passes over the obstacle.  A second method of towing maintains the flow line bundle at a constant depth below a surface of the body of water so that the bundle will clear any obstacles on the floor of the body of water.  After the flow line bundle is connected between a subsea wellhead and a producing platform located within the body of water, the space between the conduits and the tubular covering member is flooded to sink the flow line bundle to the ocean floor and to provide heat transfer between the conduits and the tubular covering member.

Abstract: ABSTRACT OF THE DISCLOSURE Edge-supported and fully supported membranes having substantially uniform thickness, and substantially parallel surfaces, and having the capacity to transmit at least about 90% of incident light with very little diffraction, dispersion or absorption of incident light are made by forming a polymer/solvent mixture, spin-coating a film of the polymer from the mixture onto a rotatable surface, which may have a release agent thereon, and, where a release agent is present, joining a frame or other support to the membrane and removing the membrane with its attached support from the surface.  Apparatus for making such membranes includes a dispenser for dispensing a polymer/solvent mixture onto a rotatable support; a device for spinning the rotatable support at gradually increasing speeds from a first to a second speed; and a device for maintaining the speed of rotation of the support at the second speed until the membrane forms.            A method for measuring accurately the thickness and index of refraction of such membranes includes directing light onto the membrane at one or more known angles of incidence, finding at least one angle of incidence, called a null angle, where the membrane reflects substantially none of the incident light, then calculating the thickness of the membrane, its index of refraction, or both, from one or more such null angles.  Apparatus for this purpose includes means for directing a light beam onto thin, optical membranes, means for varying the angle of incidence of a light beam upon the membrane, and means for detecting the angles of incidence of the light beam on the membrane, including the null angles.  The membranes are useful for example as optically trans-missive shields for reticles in projectors.
