Abstract: A method for improving the performance of a multi-user operating system includes the steps of providing a kernal mode memory region in which instantiations of kernal objects associated with each user may be stored. Each instantiations of a particular kernal object is accessed via the same virtual address. Storing instantiations of kernal objects reduces code contention for commonly used kernal objects while allowing the instantiation to retain kernal mode protections.

Abstract: A shock resistant dielectric material comprising TiO.sub.2 particles disped in a matrix material which is (1) the polyurea reaction product of a poly(tetramethylene ether)glycol-di-p-aminobenzoate prepolymer and an aromatic diisocyanate or (2) a blend of the polyurea reaction product and a cyanate ester homopolymer of bis(4-cyanatophenyl)-1,1-ethane.

Abstract: The processor is designed to develop imaged film in sheet or roll form, using a leaderless system employing edge guiding of the film. In this design the exposed film is transported in such a manner that no physical contact is made with the image area by any part of the processor until the image has been fused onto the film. The toned and fused image is permanent and smudge proof.The processor, as it is designed, has the capability of using different toners, adjusting film speed to meet toning and fusing requirements, changing fusing temperature depending on the toner at a given film speed, and adjusting the action of the air knife to improve its doctoring of the toned image prior to fusing. The processor is compact and lightweight, and the design gives due consideration to the health and safety of the operator.An important feature is the toner tray which has multiple inlets for toner with a central discharge to protect the film that is being processed from scratching.

Abstract: A hand-held transparency projector includes a housing having a recess formed in the housing for carrying a film cartridge, and a projection aperture in one end of the housing through which the images on the film in the cartridge may be projected. The housing carries a film-driving mechanism for advancing the film within the cartridge past the projection aperture when the cartridge is carried within the recess of the projector. The film-driving mechanism includes a claw mounted for slidable forward and return movements within the housing, the claw engaging perforations in the film at the end of the forward movement and advancing the film during the return movement in discrete steps of one frame.
