Title: Distortion inspection apparatus for a glass sheet
Inventor: KATSUHIKO KITAYA
IPC: G01B11/30
Filed: 1984-11-30
Abstract: In a distortion inspection apparatus for a glass sheet such as a windscreen 1, a light and dark contrast pattern 4 is sensed by an image sensor 9 through the glass sheet 1 being tested. The number of bits corresponding to light or dark portions of the pattern is detected by two value discrimination of the image data from each of a series of vertical parallel scanning lines over the surface of the glass sheet. Such scanning may be provided by moving a table 2 carrying the glass sheet 1 in a horizontal direction along guide rods 10, 11. Different orientations of the glass sheet 1 may be achieved by rotation of a shaft 3 on which the glass sheet is mounted. The degree of distortion of the glass sheet is measured by a data processor 18 in accordance with the differences among the thus detected number of bits and reference values. <IMAGE>

Patent GB-2162534-A (GB)
Title: Silicalite reforming process
Inventor: BUTLER JAMES R
IPC: C10G11/20
Filed: 1985-07-09
Abstract: A process for reforming a low octane feedstock composed of predominantly normally liquid hydrocarbons within the gasoline range to a product predominantly within the gasoline range and having a higher octane rating.The feedstock, containing branched and straight aliphatic hydrocarbons, is passed into a reaction zone and into contact with a catalyst system comprising a discrete physical mixture of a metal or metal oxide dehydrogenation catalyst and a shape-selective silicate catalyst. The silicalite catalyst is preferentially selective to a straight chain aliphatic hydrocarbons while being restrictive to branch chain isomers thereof. Conversion conditions are established within the reaction zone to produce a reformed product having an increased aromatic content and a decreased normal paraffin content.

Patent GB-2172520-A (GB)
Title: Contacting solids with liquids
Inventor: SCARLETT JOHN
IPC: B01J49/00
Filed: 1986-02-28
Abstract: For efficient regeneration of a solid, e.g. ion exchange resin, in a column it is necessary to pass regenerant liquid slowly, but uniformly so that its front moves evenly. These requirements are simply reconciled by having means defining a space 28 at one end of the column with an inlet 30 and an outlet 32. Regenerant is passed at a high rate through the inlet 30. The flow through the outlet 32 is controlled so that most (e.g. 80%) of the flow exits that way, and a desired slow flow passes through the column. Preferably the volume is first flushed by passing the full flow out of outlet 32. <IMAGE>

Title: ROV intervention on subsea equipment
Inventor: HOPPER HANS PAUL
IPC: E21B41/04
Filed: 1988-11-10
Abstract: A projecting actuation point 8 and a hollow ROV-operable tool 22 for subsea equipment 9 both have a larger diameter surface 13 23 and a smaller diameter surface 18 28, the former being nearest to the subsea equipment. The smaller diameter surface 18 of the actuation point 8 provides a coarse guidance and early alignment of the tool 22 over the actuation point and the larger and smaller surfaces, which fit closely, provide in combination two sets of interfaces for final alignment. Means for actuating the point by the tool when located comprises a torque function means in the tool cooperating with a rotatable spigot of the point and/or a stab function means in the tool cooperating with a stab receptacle of the point. The principle can be applied to a wide variety of subsea parts. The actuation point can be the spigot for a valve or choke, a point for hydraulic or electrical connection, a point for both fluid injection and valve isolation or a coupling to link a subsea component with a subsea module or to a remote power source. <IMAGE>
