  • Patent number: 4089704
    Abstract: Disclosed is a method of removing silicone rubber encapsulating material from micro-electronic circuits. The encapsulant is broken down molecularly and removed by a solution of tetramethyl-ammonium hydroxide which is diluted with an alcohol such as 2-propanol. It was found that this stripping solution causes minimal swelling of the encapsulant and leaves no significant residue which cannot be removed by standard rinsing.

  • Patent number: 4088521
    Abstract: The invention is a replacement tread for installation on a tire casing and the method of installing the tread. The replacement tread includes an endless, pre-molded central tread portion having a relaxed diameter less than the inflated diameter of the tire casing. Integral shoulder wings extend downwardly from the central tread portion and define a circular bottom edge. The shoulder wings bias the bottom edges against the tire casing effecting a seal.To install the replacement tread, the tread area of the tire casing is prepared and the tire casing inflated. The replacement tread is expanded and released onto the tire casing. Tension forces hold the replacement tread closely against the tire casing. The tread is stitched under pressure forces to remove entrapped air and to effect a fluid seal between the shoulder wings and the tire casing. Finally, the replacement tread and the tire casing assembly is cured or bonded.

  • Patent number: 4085238
    Abstract: A face of a sheet, e.g. of glass, is moved past an extrusion nozzle to deposit a plastic filament adjacent a first edge thereof. The movement is interrupted when a corner is reached. The nozzle and sheet are moved away from each other to detach the filament adjacent the corner and the sheet is rotated to present its next edge to the nozzle while retaining the continuity of the filament. The nozzle and sheet are then returned to depositing position and the relative movement resumed to deposit the filament adjacent the next edge. The apparatus includes means for raising the sheet from conveyor belts and raising the extrusion devive by a greater amount, and then turning the sheet by a suction cup arm, the sheet being supported by rollers during the turning. A detector monitors the position of the sheet and controls the operation of the apparatus.

  • Patent number: 4082589
    Abstract: Sheet material is moved along its length from a supply to a take-up spool and the material is inspected as it is moved. A garment pattern image is projected on and is moved with the material. The operator determines where the material is to be cut either from the length accumulated on the take-up spool or from the image projected on the material, and if a flaw in the material is detected, the operator determines if the flaw should be removed by identifying the pattern part in the garment from the image projected on the material where the flaw will appear. If the flaw is to be removed, the operator cuts the flaw out and splices the cut ends of material together at splice marks in the image projected on the material. The spools loaded with sheet material with this procedure are loaded in a creel, and the ends of the sheets of material from the spools in the creel are aligned in a vertically stacked arrangement and moved to a cutting apparatus where the garment pattern is cut in the stacked sheets of material.
