Title: Process for manufacturing white cement
Inventor: WEBER PAUL DR ING
IPC: C04B7/43
Filed: 1984-02-10
Granted: 1987-02-12
Abstract: The invention relates to a method of producing white cement in which a reducing atmosphere is maintained over the entire length of a rotary kiln and precalcination takes place in a preheater supplied with heat exhaust gases from the kiln. Additional fuel is delivered to the preheater in such quantity that the CO contained in the kiln exhaust gases is burnt. As a result the essential reduction processes take place reliably in the rotary kiln without any problems occurring in the preheater as a result of a high CO content.

Patent DE-3469945-D1 (DE)
Title: Supporting arrangement for rollers, especially for supporting conveyor belt rollers
Inventor: EGETO CSABA DIPL ING
IPC: F16C35/04
Filed: 1984-07-19
Granted: 1988-04-21
Abstract: According to the invention, an inexpensive antifriction bearing is located in a plastic block and the plastic block is encircled by a further plastic ring. The softening point of the plastic ring is lower by 20 DEG  C. than that of the material of the bearing block and between the softening point and melting point of the ring a difference of at least 30 DEG  C. exists ensuring that in case of excessive warming up of the bearing, the sliding on each other of the plastic block and of the outer plastic ring as plain bearing, puts the bearing out of action for a certain time. The contact surfaces of the bearing block and the ring are spherical, ensuring the compensation of possible eccentricity by self-aligning. The ring is fixed in the seat of a roller by flanging. The invention renders superfluous the otherwise indispensable high-precision single-purpose machine or horizontal lathe for boring the roller, and makes possible the application of the technology of mass production.
Patent DE-3472015-D1 (DE)
Title: Photochromic composition
Inventor: CHU NORI Y C
IPC: G03C1/72
Filed: 1984-06-20
Granted: 1988-07-14
Abstract: The organic photochromic composition of this invention comprises trifluoromethyl substituted spiro (indoline-2,3 min -(3H) napth-(2,1-b)(1,4)oxazine)(SO) dyes. This new class of (SO) photochromic compounds has a more neutral color when subjected to ultraviolet light irradiation. When used with a photochromic plastic embodiment, these (SO) compounds give the plastic embodiment a high luminous transmittance in an unactivated state, which can be darkened significantly when subjected to ultraviolet light irradiation. When an ultraviolet stabilizer is used with the photochromic compositions of this invention, the light fatigue resistance of the (SO) dye is improved and it will not hinder the photocolorability of the photochromic composition.

Patent DE-3479233-D1 (DE)
Title: Heat shrinkable covering
Inventor: STEELE ROBERT E
IPC: B29C61/10
Filed: 1984-05-17
Granted: 1989-09-07
Abstract: A heat shrinkable covering in the form of a sheet which is heat shrinkable in a longitudinal direction, and a stiffening member connected at each of two longitudinally spaced transversely extending superimposable zones of the sheet. One stiffening member has holes and the other studs in the form of arm portions which are insertable through the holes to secure the stiffening members together. The arm portions can be flattened down onto the outside of the covering to retain the stiffening members together while reducing risk of the studs interfering with items such as cables adjacent the covered article. Preferably the studs have a resiliently compressible head portion which snap fits into holes formed through the sheet adjacent the holes in the stiffening member to facilitate locating the overlapped zones of the sheet relative to one another. In use, the sheet is wrapped around an article, the stiffening members are engaged together, and the sheet is then heat shrunk. The stiffening members support the juxtaposed edges of the sheet at points intermediate the coupling points, thus resisting the tendency for the edges of the sheet to separate as a result of the hoop stresses generated in the sheet on shrinking.

Title: Methane conversion
Inventor: KIMBLE JAMES BAILEY
IPC: C07C2/84
Filed: 1986-06-05
Granted: 1989-10-12
Abstract: A method for the oxidative conversion of a feed material comprising methane, such as natural gas, to higher hydrocarbons, particularly ethylene and ethane and desirably ethylene, in which feed is contacted with a solid contact material comprising cobalt; at least one metal selected from the group consisting of zirconium, zinc, niobium, indium, lead and bismuth, preferably, zirconium; phosphorous; at least one Group IA metal; and oxygen under oxidative conversion conditions sufficient to convert the methane to the higher hydrocarbons. Substantial improvement in the conversion of methane and selectivity to ethylene and ethane is obtained by adding chlorine to the contact material. The further addition of sulfur to the contact material also improves the conversion and selectivity and permits the method to be carried out in an essentially continuous manner in the presence of a free oxygen containing gas.
