Abstract: Concentrated surfactant compositions comprise water and from 30 to 55% by weight of surfactant based on the total weight of surfactant and water. The surfactant comprises at least 8% based on the total weight of the composition of at least one anionic surfactant which is capable of forming a 20% L₁ micellar solution with a cloud point below 0°C such as an alkyl ether sulphate and preferably at least one other surfactant such as sodium alkyl benzene sulphonate, soap and or a nonionic surfactant. In the absence of electrolyte the composition is a viscous, pourable phase with hexagonal symmetry by x-ray diffraction. Electrolyte forms an optically isotropic clear, Newtonian liquid detergent composition with an x-ray scattering peak between 4 and 6 nm and sufficient-desolubiliser forms a spherulitic suspending medium capable of suspending builders such as zeolite to provide compact liquid detergents.

Abstract: A method for caching information needed by application programs from a secondary storage in which the cache memory is organized in multiple levels, each level having multiple entries, the entries of each level receiving information of a predetermined category, each entry being accessible independently. Links are defined between entries of one level of the cache memory and entries at another level of the cache memory, the links corresponding to information relationships specified by a user of information stored in the secondary storage. The use and reuse of the cache entries is based on the links. In response to a request to a file system from an application for needed information, the needed information is fetched into the cache, and in connection with fetching the needed information, other information is prefetched from the system of files which is not immediately needed. Quotas are established on information which may be fetched from a secondary storage into the cache, the quotas being applicable to file contents within a file and to the number of files within a directory. The fetching of information from secondary storage into the cache is regulated based on the quotas. Upon a request from an application program to open a file, an entry is created in a cache corresponding to the file, the entry including file header information. The file header information is retained in the cache so long as the file remains open, whether or not any file contents of the file remain in cache. The entries of three level of the cache respectively receive directory information, file header information, and file contents information.

Abstract: A field emitter includes an electron emitting structure (112) spaced from an anode structure (114), with the intervening gap (113) being substantially evacuated. The electron emitting structure (112) includes a first electrically conductive layer (128) spaced by an insulating layer (130) from a second conductive layer (132), and a generally circular aperture (134) disposed through the layers (128,132). The anode structure (114) includes an electrically conductive layer (142). Electrostatic forces, provided from a potential applied between the first conductive layer (128) and the anode structure (114), cause an electron beam to be drawn from a cathode provided by a peripheral edge portion (127a) of the first conductive layer (128) within the aperture (134) onto an adjacent surface portion of the anode structure (114). Such field emission occurs under the control of a potential applied between the first and second conductive layers (128,132) of the electron emitting structure with the second conductive layer (132) functioning as a control electrode of the emitting structure. The anode structure (114) has a phosphor layer (144) which converts the electrical energy from the electron bombardment into visible light energy. In one embodiment (Fig. 6), a potential applied to a third conductive layer (360) of the emitting structure (312) serves to focus the electron stream on the anode structure (314). Methods of manufacturing the electron emitting structures employ successive steps of layer deposition and subsequent selective etching.
