Filed: 1990-05-25
Abstract: A porous structure of a water-swellable, water-insoluble polymeric material which porous structure possesses unproved free swell capacity and is able to demonstrate said improved free swell capacity when in contact with an absorbent material such as a cellulosic fibrous web. Also disclosed is a method of making such a porous polymeric structure. The method comprising the steps of forming an oil-in-water suspension, wherein the water phase contains a water-soluble monomer and a crosslinking agent and the oil phase is a volatile organic compound having a boiling point greater than the boiling point of water. The monomer present in the water phase is polymerized to form a polymeric material having dispersed therein the oil phase. The resultant polymeric material is then dried at a temperature above the boiling point of water, such that the volatile organic compound volatilizes thereby forming pores in the polymeric material, which pores have a diameter of at least about 20 microns. The polymeric material is at least partially dried before the organic compound volatilizes so that the polymeric material possesses sufficient structural integrity to maintain the openness of the chambers.

Patent CA-2024444-A1 (CA)
IPC: G06F12/10
Filed: 1990-08-31
Abstract: A single non-privileged instruction copies a page of data from a source virtual address to a destination virtual address, regardless of which of plural electronic storage media contain the page locations, and without the intervention of any supervisory program when media and virtual addressing have been previously determined for the locations of the subject pages. The instruction is not required to specify which of the plural media it will use, does not require its user to know what backing media it will access, does not require main storage (MS) to be one of its backing media, and allows different types of physical addressing to be used by the different backing media. The instruction can lock any page for use in an MP. No physical direction of data movement is provided within the non-privileged machine instruction, which only designates virtual direction of movement. The separation of virtual direction from physical direction is done by avoiding instruction control over selection of electronic media. The non-privileged instruction can nevertheless express a preference for obtaining a copy of the destination page in an electronic medium in which the content of the page can be processed by further instructions. Also, the instruction can cause invocation of a privileged control program to avoid the need for a following condition code test instruction. A privileged instruction is also provided to wait for the completion of the unprivileged instruction and to invalidate a non-main storage (MS) medium page whether it is unlocked or locked, either correctly or incorrectly.
