Abstract: A disk storage architecture called DCD, Disk Caching Disk, for optimizing I/O performance. The DCD uses a small log disk, referred to as cache-disk, in the range of tens of MB as a secondary disk cache to optimize write performance. While the cache-disk and the normal data disk have the same physical properties, the access speed of the former differs dramatically from the latter because of different data units and different ways in which data are accessed. The objective is to exploit this speed difference by using the log disk as a cache to build a reliable and smooth disk hierarchy.

Abstract: A frangible label which includes a plurality of integrally joined layers deposited successively on a removable carrier film. One or more of the layers are electrically conductive and configured to define an electrical circuit. The label is transferrable from the carrier film onto a receiving surface and is otherwise inseparable from the carrier film without attendant disruption of the circuit. In an alternative embodiment, the label includes an adhesive layer for applying the label to a substrate, such that the plurality of integrally joined layers including the electrical circuit are transferrable to the receiving surface and are otherwise inseparable from the carrier film without destruction of the electrical circuit.

Abstract: A plastic top shell for use on a metallic top link of an expansible watch band, the top link having a hollow box-like configuration with open ends and with top and bottom walls joined by side walls. The plastic top shell comprises a molded body having a top surface and a bottom surface with end tabs protruding downwardly therefrom. The bottom surface has coplanar end portions adjacent to the ends tabs, with the top and bottom surfaces defining a thickness therebetween which is greater than the thickness of the end tabs. The body is configured and dimensioned to overlie the top wall of the top link, with the end tabs being bendable around the open ends of the top link to thereby firmly seat the coplanar end portions of the molded body's surface against the top link wall.

Abstract: Apparatus for removing debris form the ground comprising a frame which supports a rotatable cylindrical brush having bristles projecting from its axis of rotation, a rotatable shaft member extending across the width of the brush, a scraper member extending across the width of the shaft member, and a guide member configured arcuately to follow the outside of the brush. In use, the frame is movable across the ground and the brush is in contact with the ground such that the bristles contact and catch any surface debris upon leaving the ground the bristles approach the shaft member which contra-rotates with respect to the brush such that surface debris is retained by the bristles as they move upwardly proximate the guide member which guides the debris upwardly for ejection, while the scraper member maintains the shaft member free of accumulated debris.

Abstract: A roll stand for a rolling mill has a housing with a through opening. The housing rotatably supports a pair of roll shafts, at least one of which is journalled for rotation in the eccentric bores of interconnected sleeves. The roll shafts carry work rolls positioned in the through opening to define a roll pass therebetween. An adjustment mechanism is axially engageable with one of the interconnected sleeves to rotate both sleeves and thereby adjust the parting between the work rolls. The adjustment mechanism is contained in a module which is separably connected to the housing.

Abstract: In a rolling mill, a reforming chamber is positioned to receive rings of hot rolled steel rod descending along a vertical path from the delivery end of a conveyor onto a support on an underlying carrier. The carrier has an upstanding stem around which the rings accumulate to form a cylindrical coil. First, interceptor elements operate above the carrier to interrupt the descent of rings, and second interceptor elements supported on the carrier beneath the first interceptor elements operate to subdivide the coil being formed around the stem into upper and lower segments, with a gap therebetween occupied by the second intercepting elements.

Abstract: A charge generation device configured within a semiconductor region of a substrate. The device includes a source for providing an input charge and an input diffusion which receives said input charge. A barrier gate associated with the input diffusion determines a selected potential of the input diffusion. A preset diffusion presets the input diffusion to the selected potential. An output element receives the input charge from the input diffusion. A first coupling means is provided for coupling the preset diffusion to the input diffusion subsequent to the output diffusion receiving the input charge during a first clock cycle, and for decoupling the preset diffusion from the input diffusion prior to the input diffusion receiving the input charge during a second clock cycle.

Abstract: The addition of a chlorinated alkyl phosphate oil to a natural latex emulsion has enabled the formulation of water-based contact cements with the ability to instantly bond porous substrates together. The adhesives offer the user of solvent based contact cements an alternative more practical than hot melts, two-part water-based, or slower setting one-part water-based adhesives in industries where the immediate assembly of porous substrates is necessary.

Abstract: Method for waterproofing a welted footwear construction. The footwear includes an insole rib joined to an insole. The method includes applying a sealant gel to the outer surface of the insole rib and attaching a welt and an upper to the rib by stitching with a needle. The needle carries the sealing gel into and through the needle holes formed thereby forming a water impermeable seal between the welt, the upper and the rib.

Abstract: An ion accelerator for use in an ion beam implanter. The accelerator forms milliampere beams of heavy ions such as boron and phosphorous in a configuration in which the terminal ion source is replaced by a neutral beam injector. The neutral beam is formed at ground by the conversion of a focused beam of positive ions to neutral ions in a charge exchange canal. The neutral beam so formed is stripped of one or more electrons in a gas or vapor filled canal in the high voltage terminal. A 180.degree. analyzing magnet located in the high voltage terminal analyzes and directs a selected charge state to an acceleration tube parallel to the neutral beam injection tube where the selected positive ions are accelerated to ground potential.

Abstract: A cover slip holder for suspension of cover slips or slides in a biochemi reactor which includes a perimeter support constructed so that the outer surface of the support will engage the interior wall of the reactor, a plurality of coiled springs secured to the perimeter support and constructed so that cover slips can be held vertically between the coils of the springs.

Abstract: A connector for joining an end of a watchband to a watch case, the end of the watchband having a terminal link and the watch case having first lugs separated by first sockets with first apertures extending through the first lugs. The connector includes metal bottom and top components. The bottom component has a rear end configured to underlie the terminal link of the watchband, and a front end with mutually spaced projections, at least two of which define hollow guides. The top component has a rear end configured to overlie the rear end of the bottom component, and a front end with mutually spaced flanges aligned with and bent around the projections on the bottom component to form second lugs separated by second sockets. The top component is joined to the bottom component with the terminal link of the watchband captured therebetween. The first and second lugs are adapted to be received respectively in the second and first sockets.

Abstract: A propulsion arrangement for a marine vessel having a propulsion unit. The propulsion unit includes a non-rotating housing in the form of a nozzle extending along a principal axis, the nozzle having an inlet opening, an outlet and an internal diameter; a propeller mounted for rotation within the nozzle, the propeller having a plurality of blades radially outwardly delimited by a periphery; a support shaft extending along the principal axis of the nozzle and to which shaft the propeller is affixed; and a support shaft support member in the form of a plurality of arms extending substantially radially from the inner surface of the nozzle to a bearing hub for the support shaft. The plurality of arms are located upstream of the propeller, the arms being shaped so as to impart a pre-rotation on the flow of water upstream of the propeller. The internal diameter of the nozzle gradually decreases from a maximum at the inlet opening to a minimum within the nozzle and then increases towards the outlet.

Abstract: A lock cylinder set to a lock has an outer cylinder serving as a housing. In the outer cylinder, a first inner cylinder into which an electronic key is inserted and a second inner cylinder connected to a locking/unlocking mechanism of the lock are rotatably set. A connecting pin is movably held by the first inner cylinder to connect the first inner cylinder with the second inner cylinder when the pin advances. A connecting pin control mechanism advances the connecting pin to mechanically hold the advance state of the pin when a proper key is inserted and retreats the connecting pin when the key is extracted. The connecting pin control mechanism has a cam plate contacting the protrusion of the connecting pin. The connecting pin retreats when the cam plate tilts and advances when the cam member rises.
