Publication number: 20110259455Abstract: The present invention relates to an apparatus (10) for vacuum processing articles (12). The apparatus comprises a processing region (14) in which articles can be vacuum processed at a processing pressure and a loading region (18) into which articles can be loaded into the apparatus at ambient pressure. A plurality of article carriers (20) are provided for carrying articles from the loading region to the processing region along an enclosed passage (24) so that articles can be vacuum processed. The carriers (20) comprise respective sealing means (26) for sealing against an inner surface of the passage when carrying articles along the passage. The sealing means (26) resist the flow of gas or vapour past the sealing means along the passage from the loading region to the processing region so that articles loaded at ambient pressure in the loading region and carried to the processing region can be vacuum processed at processing pressure.Type: ApplicationFiled: October 19, 2009Publication date: October 27, 2011Applicant: P2I LIMITEDInventor: Charles Edmund King

Patent number: 6756093Abstract: The invention relates to cellulose casings for food products and more particularly to pigmented tubular cellulose casings and to a method for the manufacture thereof. In the method for the manufacture of pigmented cellulose casings perylene tetracarboxylic acid pigment, in admixture with an additional pigment/pigments, is incorporated in the casing in order to produce a casing, which when stuffed with food products, produces the appearance of the product being naturally smoked, mahogany colored or any shade of red color. The additional pigment is selected from the group comprising (-phthalocyanine, diazo and monoazo pigments. The pigmented cellulose casing comprises 0.4-4 wt %, preferably 1-2 wt % of perylene tetracarboxylic acid.Type: GrantFiled: June 7, 2002Date of Patent: June 29, 2004Assignee: Eriksson Capital ABInventors: Edmund King, Yngve Klingenberg, Stig Sannholm, Tuula Lindberg

Patent number: 6514553Abstract: The invention is a method of manufacturing lightweight fibrous casings constructed of abaca paper substrates suitably wet-strengthened using viscose, or viscose and resin, and subsequently viscosed a second time, and the casings made by this method. The method of this invention employs an arrangement of a die and related apparatus for the single-sided viscosing of light weight paper substrates at increased machine speeds. The die arrangement of this invention provides superior impregnation of viscose during the casing manufacturing stage, ensures smooth surfaces of both the inner and outer casing surfaces and renders the need for double-sided viscosing unnecessary, or undesirable. This new arrangement of viscose die minimizes drag upon impregnating the paper matrix with viscose and during the subsequent crucial period before coagulation of the viscose and its regeneration into cellulose has been completed; so as to permit the casing to be stretched but not irreversibly.Type: GrantFiled: February 8, 1995Date of Patent: February 4, 2003Assignee: Oy Visco ABInventors: Boris Höglund, Edmund King, Vidar Kalm

Patent number: 4753230Abstract: A wound dressing comprises an absorbent material and a surface layer of a non-absorbent wet laid apertured fabric having a smooth substantially planar surface. The non-absorbent apertured fabric preferably serves to present a soft smooth surface to the wound, maximizing conformability to the wound and minimizing any possibility of adherence of the dressing to the latter. Absorption of exudate from the wound by the absorbent material takes place largely through the apertures in the fabric. The fabric is preferably rendered non-absorbent by a coating of an acrylic latex.Type: GrantFiled: August 23, 1985Date of Patent: June 28, 1988Assignee: J. R. Crompton P.L.C.Inventors: Edmund H. Carus, Brian Tomkinson, Edmund King
