Title: Crystalline solid solutions with a rutile or polyrutile structure
Inventor: HUND FRANZ
IPC: C09C1/00
Filed: 1959-01-08
Abstract: Pigments comprise mixtures containing metal-oxygen or metal-fluorine compounds which form rutile or polyrutile lattices as host components, and metal oxides and/or fluorides as guest or additional components the cations of which possess radii which are comparable with the radii of the metal ions, or the statistical mean of the radii of the metal ions, of the host components, the additional components being present in such proportions relatively to one another that the ratio of the sum of the added cations to the sum of the added anions is substantially 1:2. Suitable host components are titanium dioxide, stannic oxide, aluminium, gallium, vanadium, chromium, iron, rhodium, lithium, magnesium, zinc, cobalt, copper or nickel antimonates, manganese, lead, vanadium, niobium, germanium, tellurium, chromium, ruthenium, osmium, or iridium dioxides, chromium, iron, rhodium, cobalt or nickel tantalates, chromium, iron or rhodium niobates, rhodium vanadate, and magnesium, zinc, manganese, iron, cobalt, nickel or palladium fluorides.  Suitable guest or additional components are the oxides or fluorides of monovalent lithium, magnesium or zinc, divalent manganese, iron, cobalt, nickel, vanadium or copper, triavalent aluminium, gallium, titanium, arsenic, antimony, vanadium, niobium, tantalum, chromium, manganese, iron or rhodium, tetravalent germanium, lead, vanadium, tellurium, chromium, ruthenium, osmium, rhodium, tin, zirconium or hafnium, pentavalent antimony, bismuth, vanadium, niobium or tantalum, hexavalent molybdenum, tungsten, uranium, or tellurium. Mixtures of additional components may be used which satisfy the requirement that the ratio of the sum of the added cations to the sum of the added anions shall be substantially 1:2 while preserving statistical electroneutrality in the lattice.  The proportion of guest or additional components may be from one-half to 50% of the whole.  The mixtures are prepared by heating the components together, preferably at a red heat.  Compounds which give rise to the metallic oxides on heating may be used instead of the oxides; thus for example carbonates, hydroxides, acetates, nitrates or formates of metals such as magnesium or zinc may be used instead of magnesium oxide or zinc oxide respectively.  If desired small amounts of a fluidizing agent such as lithium or sodium fluoride may be added.  White or coloured pigments are obtained depending upon the components used.  Numerous examples are given.  In a typical preparation the components are mixed together, heated for half hour at 1000 DEG C., pulverized, heated for half hour at 1150 DEG C., pulverized again, and then heated for one hour at 1350 DEG C.

Title: Method and apparatus for heating sheet material such as glass
IPC: C03B35/22
Filed: 1964-01-08
Abstract: <PICT:1021850/C1/1> <PICT:1021850/C1/2> <PICT:1021850/C1/3> Sheet glass is heated by, and simultaneously supported upon a gas which is caused to issue as a diffused flow through the porous wall of a plenum beneath the sheet to form a substantially uniform and continuous pressure support zone, the gas temperature being above the deformation temperature of the glass, and the gas exhausting at points within the pressure zone to a zone of lower pressure.  In a preferred embodiment, the apparatus is tilted from the horizontal.  A glass sheet is conveyed by mechanical rollers into a heating zone 11 where radiant heaters above and below the sheet raise its temperature to just below its deformation temperature.  The sheet is then conveyed into zone 12 and on to the gas support, one of its edges contacting the friction drive rollers 90 (Fig. 4).  The gas support comprises a plenum chamber 40 having a porous plate 50 forming part of its upper surface.  Tubes 56 open out on to the upper face of plate 50 and extend through chamber 40 to atmosphere.  Gaseous combustion products at a temperature of about 1200 DEG  F. are blown into the plenum 40 and these percolate through the porous plate 50 beneath a glass sheet G heating the latter to above deformation temperature and supporting it thereon.  The tubes 56 forming the exhaust ports form between 5 and 50% of the surface area of plate 50 and have a diameter of 0.050 inch compared with the plate pore sizes of 0.0002 to 0.025 inch.  The proximity and size of the tubes causes the gas to exhaust with little movement.  Radial heaters 36 in the roof of zone 12 prevent the sheet from warping. The sheet then passes between upper and lower cooling boxes 112, 110, and is supported upon the gases issuing from box 110 to cool it to a temperature of about 600 DEG  F.  The gases support the glass sheet at a distance of from 0.001 to 0.050 inch from the plate 50. The porous plate may be stainless steel or other refractory material.  An alternative plenum chamber and supporting plate is described using Fig. 7 (not shown). Where desired, the porous support bed may be curved, either in its entirety for conveying curved sheets or progressively, as from flat to curved, for bending flat sheets as they travel along the support bed at the deformation temperature.

Title: Gear change mechanism for an automatic gearbox of a motor vehicle
Inventor: STELTER NORBERT DIPL-ING
IPC: B60K20/02
Filed: 1997-05-22
Abstract: A shifting arrangement for an automatic transmission of a motor vehicle controlled by an electronic control apparatus includes a selector lever to be operated manually. By displacement of the selector lever in a first shifting lane, the different transmission speeds can be selected. After shifting the shifting lever by way of a transverse lane into a second shifting lane, the desired forward speed can be manually engaged by means of the same. The shifting operation is picked up by means of a sensor which influences a shifting unit. The shifting unit effects the maintenance of an actually engaged transmission speed during a change of the shifting lane.

Title: Linear motor
Inventor: KIKUCHI TAKAO
IPC: H02K41/02
Filed: 1979-01-08
Abstract: PURPOSE: To better the responsiveness with a lighter armature by prventing the rolling of the armature utilizing a bias moment due to the deviation of the magnetic center of the stator and the armature.  
     CONSTITUTION: An arm 19 having an antirolling roller 18 pivoted thereon is provided so projected on the side facing the guide wall 16 of a armature 11 that the roller 18 turns against the inner surface of the wall 16. In addition, a slider tooth 20 provided on the undersurface of the armature 11 is biased to the side to the  extent that the center of a tooth positioned at the right angle to the moving direction A of the armature won't take the roller 18 out at the center of the stator tooth  13. Thus, the armature 11 is properly deviated from the magnetic center at the  right angle to the direction A of the stator 12. Therefore, the stator 12 has a component of propelling the armature and a component of averting thereof to the wall 16,  so that the roller 18 hits against the wall 16 to move the armature 11 along the wall  16 and the reference plane 15. This can better the responsiveness of the armature  while improving the reliability of the motor.

Title: Exposure volume controller of copying machine
Inventor: FURUICHI YASUSHI
IPC: G03G15/04
Filed: 1981-01-05
Abstract: PURPOSE:To realize the control of the exposure with high accuracy and high stability by means of an inexpensive photodetector available in the market, by using a quantity of light detecting means having the spectral sensitivity that substantially cuts the infrared rays. CONSTITUTION:A filter that cuts the >=700mmu beams down to <=5% for instance is put in front of a photodetector PD as a light receiver 4 in an exposure controller 5 of a copying machine. As a result, the stable quantity of light can be obtained to a photoreceptor and under any environment. Accordingly it is unnecessary to set the photoreceptor at the same spectral sensitivity as the photoreceptor. Then the quantity of light can be simply controlled by cutting the long wavelength light having no sensitivity to the photoreceptor by a filter. In such way, the exposure can be controlled with high accuracy and high stability by means of an inexpensive photodetector available in the market.
