Title: Ethyl benzene sepn. from mixts with xylene isomers - using zeolite adsorbants selective for the isomers
IPC: B01J20/18
Filed: 1976-07-13
Abstract: Ethyl benzene is separated from mixtures contg. ethyl benzene and several xylene isomers by contacting the mixture under adsorption conditions contg. a strontium-exchanged Type Z or Type Y zeolite. The xylene isomers are selectively adsorbed, ethyl benzene being excluded from the adsorption process and recovered as a very pure product. The above adsorbants are selective for all xylene isomers as compared for ethyl benzene and have higher selectivity for p-xylene as compared for toluene. Therefore, ethyl benzene is separated in 98% yields or higher, and has a purity of 98% or more (as% 8C aromatics present), suitable for use as a raw material in the prepn. of styrene monomer. Separation of ethyl benzene in high yields and purity from its mixts. with several xylene monomers is effected by contact with an adsorbant comprising an Sr-exchanged Type X or Type Y zeolite. The xylene isomers are selectively adsorbed, the ethylen benzene being excluded from the adsorption.

Patent FR-2360892-A1 (FR)
Title: -ray gamma-ray camera system for imaging of isotope distribution - esp. in human body, has collimator grating and pref. germanium detectors
Inventor: STEIDLEY JOHN W
IPC: G01T1/29
Filed: 1977-02-09
Abstract: The incident energy passes through the grating collimator and thus forms in its original pattern upon a large number of detector components lying in a plane behind the collimator. Each detector component is typically of high purity p-Ge made by applying an n-contact onto one side and a p-contact onto the opposite side of a flat rectangular crystal. The two faces are grooved in parallel lines but mutually at right angles on the opposite faces. In this way, semiconductor strips are formed on both sides. These two sets of strips are connected to series resistors connected respectively to preamplifier stages, which thus give coordinate output signals in the x and y directions. A voltage is applied across the system, so that each detector component resolves the absorbed photons. The charge values corresp. to the output signals, are summated to give the energy level for the spatial data and energy data. The resolution of the system is obtd. by the collimator grating, which ensures that only radiation which is incident perpendicularly to the collimator passes through, oblique radiation being eliminated and absorbed. The appts. provides high resolution due to the design of the collimator and in addition provides a rapid and simultaneous image.
Patent FR-2382123-A1 (FR)
Title: Wound magnetic strip elements - with corrugations on outside of straight strip straightened by bending on edge
IPC: H02K1/16
Filed: 1977-02-24
Abstract: Stators and rotors of electrical machines can be wound from magnetic strip in a way which ensures a continuous flush contact of all turns on the inside but an interrupted contact on the outside. In the case of a stator, e. g the magnetic strip has slots (5) punched out along one side. On the other side, corrugations (2) of trapezoidal shape are pressed in from the edge (3) to the bottom of the slots (6). When the strip is wound to a coil, the corrugations straighten out but leave intermittent thinner strip sections on the outside of the wound coil. The inside heads (4) of the teeth, however, form a continuous flush contact with those of the next turn. Instead of trapezoidal, the corrugations can have a conical or pyramidal shape.
