A divider assembly for installation in a tool box or chest drawer to provide separate drawer areas for the storage of various grouped articles. Perimeter rails are joined by corner clips to maintain a rectangular shape of the divider assembly. Divider rails extend intermediate perimeter rails to form storage areas of various shapes and sizes. Divider clips receive the divider rail ends. Projections and recesses on the divider clips and the perimeter rail members confine the divider rails against displacement. Flexure of the divider clips permit snapped engagement of the clips with the perimeter rail member.

The invention belongs to the field of manufacturing high-temperature refractory metal target materials, and particularly relates to a process for manufacturing a high-density molybdenum-niobium alloy sputtering target material. The process comprises the steps of mixing raw materials; loading mixed material powder in a rubber sleeve; performing cold isostatic pressing operation, after the pressure is increased to a certain pressure, maintaining the pressure for a period of time, then depressurizing, and finally taking out a pressed blank from the rubber sleeve; carrying out vacuum sintering or hydrogen protection sintering; carrying out hot isostatic pressing operation directly on the sintered blank; performing hot rolling operation, namely performing metal sleeve rolling on a molybdenum-niobium alloy, and annealing after hot rolling to remove stress; and carrying out machining operations such as grinding to obtain the final required product size. The process is simple in processing steps and convenient to operate, the purity and the relative density of the manufactured molybdenum-niobium alloy sputtering target material all meet the use requirements in the film coating field of high-end electronic products; and the process is low in production cost, wide in production size range, and convenient for industrial batch production.

The invention relates to a nanofiber compound-based shale formation blocking agent for drilling fluid and a preparation method. The blocking agent is prepared from the following raw materials: bagasse, a dispersant, nano silica, nano graphite and deionized water. A nanofiber compound method is adopted to form the efficient blocking agent for effectively blocking nano pores and micro-nano cracks bycompounding various types of nano particles, the method is simple and reliable, and the prepared shale blocking agent has little influence on the performance of the drilling liquid, but has an obvious shale blocking effect. The blocking rate of base mud added with the amount of 3.0 percent by weight of a nanofiber compound in a shale core exceeds 96%, while under the conditions of high temperature and high pressure (180 DEG C/6MPa), the blocking capacity remains basically unchanged (higher than 93%), and the treatment agent is non-toxic, has no adverse effects on environment, has acute toxicity EC50 which is greater than 60000, and is an efficient shale blocking agent.

Frost covers are described that define an enclosure for an individual plant or group of plants to protect the sides and lower portions of the plants as well as their tops from frost damage. Each cover is shaped to envelop a single plant or group of plants and is provided with a retaining mechanism, such as an elastic band or drawstring, which allows the frost cover to be secured to the plant or group of plants against winds. The covers are inexpensive, reusable, disposable, and may be formed into a variety of shapes and sizes to accommodate a wide variety of sizes of plants and groups of plants. The frost covers are fashioned from a semi-transparent, air-permeable and moisture permeable membrane that permits some sunlight and water to pass through the membrane while causing frost to form atop the membrane rather than on the covered plant.

A lifting fitting for lifting a series of elements of different sizes in a wind turbine is proposed. The lifting fitting has a base plate having at least one central slotted hole shaped to accommodate a fastener for fastening the lifting fitting to an element to be lifted, at least two outer slotted holes each shaped to accommodate a further fastener for fastening the lifting fitting to an element to be lifted. The outer slotted holes are arranged transverse to the central slotted hole. The lifting fitting is connected to a lifting apparatus for lifting the element. A method of assembling the series of elements is proposed. The elements are successively lifted into place. The lifting fitting can be used in the assembly of a wind turbine tower having individually liftable tower sections for lifting the tower sections into place.

The over-slippers are constructed of elastic material such as spandex. The over-slippers each have a plurality of resilient pads fixedly attached to the underside of the sole portion of each slipper. The soles and the pads form a protective layer between the cleats of a standard bike shoe and any surface that the wearer of the bike shoe may be walking on. The pads of the slippers are located under the standard cleat locations found on a standard bike shoe. A preferred embodiment includes strap handles fixedly attached to the front and rear rim of the shoe receiving aperture to allow for easy attachment or removal of the slipper.

There is described a method for applying foil material (200) onto successive sheets (S), especially sheets for the production of securities, such as banknotes. In a first step, individual sheets (S) are transported in succession along a sheet transport path. In a second step, at least one continuous band of foil material (200) is applied onto the individual sheets (S) along a direction substantially parallel to a direction of displacement (A) of the individual sheets, thereby forming a continuous flow of sheets linked to one another by the said at least one continuous band of foil material (200). In a third step, the said at least one continuous band of foil material (200) is cut by means of a laser beam (L) such that the continuous flow of sheets is again separated into individual sheets (S) with portions of foil material (200*) remaining on the sheet. The cutting is performed at positions located on the sheets (S) such that said portions of foil material (200*) remaining on the sheets do not extend beyond leading and trailing edges of the sheets (S). Waste portions (205) of said at least one continuous band of foil material (200) that are not to remain on the sheets (S) are seized prior to cutting by the laser beam (L) and are held throughout the cutting process. There is also described an installation for carrying out the above method.
