Abstract: ABSTRACT                  AIR SEPARATION            In order to provide 'ultra high purity' nitrogen having diminished concentrations of light and heavy impurities in comparison with nitrogen produced by conventional cryogenic air separation, the nitrogen product from a conventional cryogenic air separation column is introduced into the bottom of a liquid-vapour contract column 2 fitted with a condenser 8 to provide reflux.  A liquid nitrogen stream having a reduced concentration of heavy impurities is withdrawn from the column 2 through an outlet 22 situated at a level a few trays below the top tray in the column 2.  The liquid nitrogen is then subjected to two stages of flash separation.  In the first stage the liquid is passed through valve 24 into a phase separator 26.  In the second stage, the resulting liquid from the first stage, having a reduced concentration of light impurities, is passed through valve 32 into a phase separator 34.  Liquid nitrogen product is withdrawn from the phase separator 34 through outlet 38.

Electrical sockets are mounted in the housing, and fluorescent lamps are electrically connected to the sockets.  Supports connected to the wall in spaced-apart relation tothe sockets are releasably engageable with the fluorescent lamps for support thereof.  A typical wall is formed with a recess having a given length in a first direction.  The support is made of a flexible material and is formed with a stem, clips extending from one side of the stem for embracing and supporting the fluorescent light, and a head extending from another side of the stem and engageable in the recess.  Arms lead away from the head and wall at first locations adjacent to and on either side of the stem and towards the wall at second locations farther from and on either side of the stem.  Feet are respectively at distal ends of the arms and engageable in the recess.  The feet have a separation in the first direction normally slightly different from the given length and are resiliently biased by the arms for retention in the recess.  At least one of the head and feet are received in the recess with a small tolerance in a direction orthogonal to the first direction.

IPC: G01N27/417
Filed: 1990-12-10
Abstract: A METHOD AND DEVICE FOR SENSING NITROUS OXIDE          Abstract A method for identifying and determining the concentration of nitrous oxide in a gas containing nitrous oxide, oxygen and nitrogen is disclosed.  A negative voltage is applied across a set of electrodes separated by an electrolyte wall.  The voltage is of such a magnitude to produce an electric current which is on a plateau.  The current is measured initially using air or oxygen as a test gas.  After this reading is taken the gas containing nitrous oxide in oxygen and air is measured for its current and the concentration of  nitrous oxide is deter-mined using the two measured currents.  The negative voltage can be applied at two different magnitudes to have two currents measured.  Nitrous oxide containing mixtures would yield equivalent current readings.

Abstract: Abstract Apparatus for the Fail-Safe Display of an Indicating Diagram An apparatus for the fail-safe display of an indicating diagram is disclosed which allows the use of high-resolution screens (HB) with individually addressable dots and eliminates the need to derive a check code from the serial picture-data stream, which derivation poses problems at very high refresh memory readout fre-quencies. To generate the check code, the picture data which are transferred into the refresh memory (BW1) are transferred in parallel into an additional, like memory (BW2) which is not followed by a screen, and read immediately thereafter from the additional memory into a check-code generator (P). In a control computer (SR) calling for the indicating-diagram display, a check code generated by the check-code generator is compared with a previously stored reference code. If the two codes do not match, an error indication is initiated.            Figure K. Pierick et al 1-1-2-2

Title: Stretch-tape wrapper with positive-braking action
Inventor: FERBER NORMAN I
IPC: B65H75/18
Filed: 1991-07-31
Abstract: The wrapper of the invention includes a roll of stretch-tape on a central core, in its basic form, with a single end extension.          A cap is secured at the remote end of the extension, and an incompressible sheath encircles the extension to freely rotate when the wrapper is used with tape being drawn from off the roll.  The cap is dimensioned to prevent the sheath from separating from the extension, and is grasped by the heel of the hand of the user to prevent rotation of the extension when the tape is stretched, to be broken from the roll.  Because the cap is of greater dimension than the sheath, the wrapper can be hand-held and operated at any angle as the circumstances of use dictate.    In a second version, a pair of end extensions can be employed, making the use two-handed instead of one-handed, with the same type of braking action being provided by the caps being grasped by the heels of the hands of the user at either end preventing rotation of the stretch-tape roll.
