Abstract: VALVE ACTUATOR FOR POCKET LIGHTERS ABSTRACT A fuel burning lighter, optionally having an adjustable flame height, comprising a supply of liquified gaseous fuel burner means communicating with the fuel supply, valve means positioned between the fuel supply and the burner means, means to provide first force to retain the valve means in a closed position to prevent gaseous fuel from passing therethrough, and means to provide second force less than the first force biasing the valve means toward an open position. The second force providing means normally provides sufficient force to move the valve means to an open position when the first force is relieved or released from acting upon the valve means.

Abstract: HIGH CURRENT CONDUCTORS AND HIGH FIELD MAGNETS     USING ANISOTROPIC SUPERCONDUCTORS                         ABSTRACT          Improved  conductors  and  superconducting  magnets  are described utilizing superconducting materials exhibiting critical field anisotropy.   This anisotropy is one in which the ability of the superconductor to stay in a superconducting state depends on the orientation of a magnetic field applied to the superconductor with respect to the direction of current flow in the superconductor. This anisotropy is utilized in the design of conductors and  magnet  windings  comprising  the  superconductive material and specifically is directed to magnet windings in which the direction of high critical current through the  superconductor  is parallel  to  the magnetic  field produced by current in these windings in order to obtain high critical fields.  Particularly favorable examples of a  superconducting material  are  the  so-called high Tc superconductors in which the primary supercurrent flow is confined to 2 dimensional Cu-O planes.  By arranging the superconductive windings  so  that  the Cu-O planes  are substantially parallel to the magnetic field produced by current in these windings, the windings will be able to withstand high fields without being driven normal.  This maximizes  the  magnetic  field  amplitudes  that  can  be produced by the magnet.

Title: Gas and oil well pumping or swabbing device and method
Inventor: COYLE GARY W
IPC: E21B43/00
Filed: 1988-10-12
Granted: 1991-07-16
Abstract: ABSTRACT OF THE DISCLOSURE The pumping or swabbing device and apparatus of the invention utilizes an elongate barrel slidable upwardly and downwardly on an axial rod which carries a valve element for closing on a valve seat provided interiorly of the barrel to close passage through the barrel of down-hole pressure fluid and cause such fluid to raise barrel and rod of the device through a gas and oil well casing to the wellhead, where liquid above the device is pushed to discharge at the wellhead. Spring actuated detent latching elements coact with a pair of longitudinally spaced lower and upper latching recesses to hold the barrel and rod together against relative movement in lower valve-closed and upper valve-opened positions. A sealing packer encircles the barrel and a by-pass passage thereinto leading from and back into the barrel flow passage provides sealing pressure within such packer as the device rises in the well casing. A manually or pressure operated latch provides for holding the device in the wellhead as desired.

Abstract: ABSTRACT      An interleaving method and apparatus suitable for burst error correction occurring in data transmission or reading of recording medium.  In the interleaving method in which data to be transmitted is once written in a storing means and then read to be output in order different from a writing order, a plurality Or counters for dividingly generating addresses of the storing means is used; and an operational relationship between the counters is changed between writing and reading of the storing means.  ROMs for address translation can be omitted so that the number of gates is reduced very much. Thus, a reasonable interleaving apparatus suitable for LSI formation can be realized.  In addition, since ROMs for address translation interposed between the counter and the storing means in the convetional apparatus are omitted, access time for the storing means can be shortened substantially.

Title: Method of and apparatus for manufacturing biaxially oriented film
Inventor: TAKASHIGE MASAO
IPC: B29C48/10
Filed: 1989-03-30
Granted: 1994-11-15
Abstract: The present invention relates to a method of and an apparatus for manufacturing biaxially oriented film.  A tubular original film which has been extruded by an extruding die is biaxially oriented by heat and air injected to the inside portion thereof being conveyed to nip rolls each having an individual circumferential speed.  The temperature of heat to be applied to the film is controlled on the basis of the detected film thickness for the purpose of obtaining a uniform film thickness distribution.  Furthermore, the film can be made uniform by adjusting the outer diameter of the bubble-shaped oriented film by adjusting the distance between two sets of nip rolls on the basis of the measured width of the film.  In addition, when the thus-oriented film is subjected to a heat treatment, temperature of heat is arranged to be a predetermined temperature as to prevent adhesion of the films.
