Abstract: Esters of monosaccharides and their lower alkyl glycosides are effective both as surfactants and as bleach activators (peracid precursors). The compounds are non-toxic and biodegradable. They act as nonionic surfactants and are effective in soil removal from textiles, e.g. of fatty soiling. In the presence of a hydrogen peroxide source, the sugar derivatives are perhydrolyzed during the washing process to form long-chain peracid. This enhances the bleaching effect, especially on hydrophobic stains.

Abstract: The present invention is intended to improve the track recording density and track density of a magnetooptic recording medium (1) to prevent the deterioration of characteristics due to the variation of reproducing power. After recording information signals on a magnetooptic recording medium having at least a reproducing layer (3), an intermediate layer (4) and a record hold layer (5), the direction of magnetization of the reproducing layer is turned in the direction of an initializing magnetic field. The reproducing layer (3) is irradiated with a laser beam and a reproducing magnetic field is applied to the same simultaneously to heat the reproducing layer (3) in a temperature distribution so that a region remaining in an initialized state, a region to which information signals are transferred and a region magnetized in the direction of the reproducing magnetic field are formed. Magnetic signals are read from the region of the reproducing layer to which information signals have been transferred. <IMAGE>

Abstract: The interchangeable upper of the disclosed footwear includes a foot covering adhesively secured to an insole molded of relatively flexible, shock-absorbent material to a desired shape, size and thickness, and having a narrow shoulder surrounding its upper surface. This insole is received in a one-piece outsole molded from a material having memory, so as to always seek to return to its original molded shape, which has a bottom corresponding in size and shape to the insole which is surrounded by an upstanding wall having a height which corresponds to the thickness of the insole and a narrow lip extending inwardly from its upper edge. During molding, the bottom may be made flat or, alternatively, the portion of the bottom from the heel to the widest part of the foot may be made flat and the portion forward thereof gently curved upwardly from the plane of the flat portion. The lip on the outsole mechanically engages the shoulder on the insole, and because the outsole attempts to return to its molded shape any tendency of the outsole to gap at the upper edge with stepping movement is essentially prevented. The material of the outsole is sufficiently elastic to secure insole and outsole together, yet to be stretched the small amount necessary to release the lip from the shoulder for removal of the outsole.

Abstract: A method of packaging a beverage having gas in solution has an open topped container 1 in which is located a hollow insert 5 having a restricted aperture 12. The container is charged with the beverage such as beer 15 so that the aperture 12 is submerged in the beverage and the container is sealed to form a headspace 19 which is pressurised, preferably by dosing with liquid nitrogen. Following sealing the container is rapidly inverted to locate the aperture 12 in the headspace 19 so that gas pressures in the insert chamber 10 and the headspace 19 come into equilibrium. With the fluid contents in equilibrium, or substantially so, the package is reinverted so that gas under pressure in the insert chamber 10 communicates directly by way of the aperture 12 with beer in the chamber 10. Upon opening of the headspace 19 to atmospheric pressure for dispensing the beer a pressure differential is developed by which gas from the insert chamber 10 is initially ejected through the aperture 12 into the beer 15 to effect in the development of a froth on the beer 15. Beer 30 which may flow into the insert chamber 10 prior to the aperture 12 moving to communication with the headspace 19 is accommodated within a well 13 of the insert chamber 10 remote from the aperture 12 to alleviate the ejection of such beer 30 into the beer 15. <IMAGE>

Abstract: A processing system includes memory page selection of multiple memory pages in an interrupt environment. The processing system includes a processor and memory page selection control for selecting one memory page responsive to a first address generated by the processor and another memory page responsive to a second address generated by the processor. The memory page selection control includes a page latch which can be overridden by an interrupt to permit the processor to service an interrupt from one of the pages but which returns the processor to the memory page from which it was fetching program instructions at the time of the interrupt. To coordinate page selection, the processor executes program instructions from dedicated paging instructions including interface modules, decode modules, and transition modules stored in each page which are configured to assure smooth page transitions and efficient interrupt servicing.

Abstract: The relatively harsh "ride" of a non-pneumatic tire ("NPT") is greatly improved by a ring of elastomeric material referred to as a "ride-enhancing insert" ("RI"). The RI is pre-positioned on the outer surface of a wheel rim on which the NPT is to be molded of elastomeric material, most preferably a polyurethane, which is peculiarly well-suited to survive normal use on various vehicles, particularly as a replacement for a conventional spare tire, or "minispare" in an automobile. The RI is surprisingly tolerant of stress and heat loads generated by operation of the NPT/RI. The RI has a large effect on the spring rate of the NPT when deflected over a cleat, and a reduction in spring rate when deflected over a smooth laminar surface. This is of particular importance since the deflection over a cleat is where the improvement in ride is most noticeable. The degree of ride-enhancement can be tailored by choosing the size and shape of the RI, along with the physical properties of the elastomer from which it is formed. <IMAGE>

Abstract: A rotary bushhammering apparatus comprises a head (26, 119) having a hub (15, 115) connected for rotation to a rotary shaft (16, 112). The head (26, 119) in turn comprises a plurality of freely rotating rollers (12, 117) the axis of which is disposed radially to the rotation axis of the head, each roller having radially projecting points (14, 118) on its peripheral surface, so that on rotation of the head (26, 119), it is driven to roll on a surface to be worked, the points thus scratching said surface to be worked. A mass (20, 121) weighing on the rollers (12, 117) is supported between the rotary shaft (16, 112) and head (26, 119) so that said rollers (12,117) can exert pressure against the surface to be worked, the mass (20, 121) being prevented from rotating with the head (26, 119). Advantageously, the head (26) can be connected to the rotary shaft (16) by interposition of an articulated joint (25) enabling the free inclination of the head (26) rotation plane with respect to the rotation axis of the shaft (16). In this way, the working of the curved surfaces is permitted. <IMAGE>

Abstract: A system and method to compensate for effects of a recording medium such as film on image data retrieved therefrom. Red, green, blue, and infrared light is sequentially transmitted through film having an image exposed therein to the system which captures corresponding images. The infrared image maps the location, boundaries and intensities of the media defects. The map is employed combinatorially with the other captured images resulting in an image from the film free of the effects of the film defects. In one embodiment the effects of the imperfections are divided out from the red, green, blue spectra in an operation dividing out the infrared image data on a pixel-by-pixel basis. In an alternate embodiment wherein the imperfections substantially prevent transmission of IR light therethrough, the IR image map of the defects is nevertheless employed with an automated fill-in algorithm more effectively utilized due to the precision with which the defect boundaries are known. <IMAGE>
