IPC: H01L49/02
Filed: 1966-06-15
Abstract: 1,182,422. Etching. PLESSEY CO. Ltd. 9 June, 1967 [15 June, 1966; 1 March, 1967], Nos. 26666/66 and 9772/67. Heading B6J. [Also in Division H1] Different metals in a multi-layer structure are etched by applying a positive working photo-resist to the outer layer of metal; exposing a first pattern and developing to remove the exposed resist; exposing a second pattern in the remaining resist; etching the outer layer of metal under the exposed first pattern; and then at some stage after this first etching step, developing the second pattern is permit the outer layer of metal under the exposed second pattern to be etched. In an example, successive layers (5, 6, 7) (Fig. 3, not shown) of aluminium nickel and aluminium are deposited on a glass substrate 4 and covered with a positiveworking photo-resist (8). The resist is exposed and developed to leave unexposed resist over areas 1, 2 and 3, Fig. 2, and then a second pattern is formed by exposing resist over area 3 only. The exposed aluminium is etched away with an ammonium persulphate/orthophosphoric acid mixture and then the second pattern is developed (Fig. 6, not shown). The exposed nickel layer is removed with dilute nitric acid (Fig. 7, not shown), and then the persulphate/phosphoric acid mixture is again used to not only remove the lowest layer (5) of exposed aluminium, but also to remove the top layer (6) in area 3. The remaining photo-resist, i.e. on areas 1 and 2, is then removed to leave a three layer metal pad on areas 1 and 2 and a twolayer interconnecting part in area 3. The process is applicable to more than two patterns.

Title: Process for producing oxo alcohol having a low aldehyde content
Inventor: GILBERT WILLIAM IRWIN
IPC: C07C29/141
Filed: 1961-03-20
Abstract: Oxo alcohols having a low aldehyde content are produced by reacting hydrogen and carbon monoxide with an olefin in the presence of a hydroformylation catalyst at an elevated temperature and pressure to obtain a mixture containing an aldehyde having one more carbon atom than the olefin, subjecting the hydroformylation reaction mixture to catalytic hydrogenation to obtain a product containing an alcohol and unreacted aldehyde, removing therefrom polymer formed during the hydroformylation and hydrogenation reactions, removing from the polymer-free product olefin not converted to aldehyde, removing from the olefine-free product a first out boiling in the range 66-218 DEG C. and thereafter treating the remaining product with an alkali metal borohydride to reduce the aldehyde content of the remaining product. The remaining product is preferably treated with the borohydride at a temperature of 10-121 DEG  C. and a pressure of 0-70 kilogrammes/sq. cm. gauge.  The preferred olefines for use as starting materials are those containing 3-20 carbon atoms. The hydrocarbonylation reaction is preferably carried out at 149-191 DEG  C. and 210-350 kgs./sq. cm. in the presence of a cobalt salt of an organic acid as catalyst. The hydroformylation product may be demetalled by heating it to a temperature sufficient to decompose the metal compounds and collecting the free metal on an inert material such as pumice.  The demetalled product is then passed into a reactor packed with a hydrogenation catalyst such as nickel at a temperature of about 149-204 DEG  C. and a pressure of 3.5-350 kgs./sq. cm. and the product treated as described above.

Inventor: DAVENPORT FRANCIS L
IPC: D21F7/08
Filed: 1998-01-23
Abstract: A calender belt for the compliant calendering of a paper web includes an endless base substrate, a staple fiber batt attached to at least the outside of the endless base substrate, and a polymeric resin material totally impregnating the fiber/base composite structure comprising the endless base substrate and the staple fiber batt to a substantially uniform depth. That depth may be such that the polymeric resin material does not reach the base substrate, or partly or completely impregnates the base substrate. A layer of polymeric resin material is built up upon the staple fiber material to a predetermined thickness. Once the polymeric resin material is cured, it is ground to a desired smoothness without exposing any fiber on the ground surface. That the penetration of the polymeric resin material into the staple fiber batt, and possibly into the base substrate, is to a uniform depth enables the calender belt to provide a uniform pressure pulse as it passes with a paper web through the nip in a compliant calender. <IMAGE>
