Abstract: The disclosed single pass raised bed preparation system makes use of one or more rows of adjustable height compact discs (4), to mulch up stubble and loosen the soil in the depressed furrows prior to the action of a bed-forming implement (6) mounted behind the discs. At the same time the raised beds are cultivated by two rows of compact discs, with the second row (2) opposite handed to the leading row (1). A roller or crumbler (7) levels and conditions the beds, so that both the beds and the furrows are restored in a single pass to a condition ready for sowing.

Abstract: A method of operating a communication network having multiple stations, each able to transmit and receive data, so that the network can transmit a message from an originating station to a destination station via at least one opportunistically selected intermediate station. Stations wishing to transmit data transmit probe signals which are responded to by other stations, thereby to identify available stations. When a station has data to send, it transmits probe signals with Request to Send messages, identifying the data to be sent. When a station receives such data for onward transmission, it transmits its own probe signals with a Request to Send message and including identification information relating to the data. The Request to Send messages are received by other stations in the vicinity, so that they serve as an implied acknowledgement of the receipt of the data by the forwarding station without the need for sending explicit confirmation.

Abstract: Self relieving seals of this invention comprise an elastomeric seal body having a first sealing surface and a second sealing surface for contact with respective drill bit sealing surfaces. The seal includes a pair of external surfaces that each extend along the seal body between the first and second sealing surfaces. The seal includes one or more relief ports that are disposed through the seal body and that have openings through each of the seal body external surfaces. The relief port can be specially configured, e.g., have different diameter sections of constant or variable dimensions, to provide a degree of control over pressure equalization through the seal body when the seal is loaded within the drill bit. The seal may include an element, e.g., solid, tubular, or porous, disposed within the relief port to provide a further desired degree of control over pressure equalization through the seal when the seal is loaded within the drill bit. Surface features, on the seal or the drill bit, can be provided to offset the relief port opening from the rock bit so that it is not blocked off. The seal can include a valve mechanism to provide a further degree of control over fluid passage through the relief port.

Abstract: Methods and apparatus for masking glazing panels while leaving a peripheral region free of masking material. The method can include providing a masking material and applying the masking material to at least one major surface of the glazing panel. The glazing panel can be either a single glass pane or a multi-pane insulating glass unit. After application to at least one major surface, a laser can be used to describe a closed path on the major surface, thereby cutting or scoring the masking material through to the glass major surface. The path demarcates a central, masked region from a peripheral masked region of the glazing panel. In one method, the laser cuts a muntin bar pattern having several central regions. The laser power can be selected and/or adjusted such that the masking material is burned through, without damage to the underlying glass material and any coatings on the glass material. After cutting through the masking material to define the peripheral masked region, the peripheral masked region can be peeled or stripped off from the masked glazing panel. The remaining panel thus has a protective mask about the central region while leaving the peripheral region unprotected. The resultant masked glazing panel may be assembled into a window unit by mounting window frame members about the four sides of the glazing panel. The window frame members may thus have a tight and durable fit directly to the glass in the peripheral region, while the central region of the glazing panel remains protected by the masking material.

Abstract translation: 用于掩蔽玻璃板的方法和装置，同时留下没有掩蔽材料的周边区域。 该方法可以包括提供掩模材料并将遮蔽材料施加到玻璃板的至少一个主表面。 玻璃板可以是单个玻璃板或多层玻璃中空玻璃单元。 在施加到至少一个主表面之后，可以使用激光来描述主表面上的封闭路径，从而将掩模材料切割或刻痕到玻璃主表面。 该路径将中心的掩蔽区域从玻璃板的外围掩蔽区域划分开。 在一种方法中，激光切割具有若干中心区域的模板。 可以选择和/或调节激光功率，使得掩蔽材料被燃烧，而不会损坏下面的玻璃材料和玻璃材料上的任何涂层。 在切割掩模材料以限定外围掩模区域之后，外围掩蔽区域可以从掩蔽的玻璃板剥离或剥离。 因此，剩余的面板具有围绕中心区域的保护罩，同时使外围区域不被保护。 通过将玻璃框架构件围绕玻璃板的四个侧面安装，所得到的蒙面玻璃面板可以组装成窗单元。 因此，窗框构件可以紧密且耐用地配合到周边区域中的玻璃上，而玻璃板的中心区域仍然被掩蔽材料保护。

Abstract: A method for designing a drill bit comprising modeling a domain between a drill bit and a surrounding wellbore. A region is defined within each of a plurality of flow paths through which fluid travels through the domain. An allocation of flow among the plurality of flow paths through the domain is determined and the drill bit is modified such that the allocation of flow is substantially uniform among the plurality of flow paths. A drill bit comprises a bit body having a plurality of blades projecting there from, wherein at least one blade has a greater length than at least one other blade. A plurality of nozzles, or ports, are disposed on the body and a plurality of junk slots are formed between adjacent blades so that the flow of fluid through each of the plurality of junk slots is substantially uniform.

Abstract: A rotary cone rock bit includes one or more hole cleaning nozzles and one or more bit cleaning nozzles. The hole cleaning nozzles of one drill bit define a projected fluid path disposed at a lateral angle of less than six degrees in order to achieve a large impingement pressure on the hole bottom. The bit cleaning nozzles of the same drill bit define a projected fluid path disposed at a lateral angle of at least six degrees in order to pass within 0.5 inches of the teeth on leading edge of the lagging roller cone. This results in a drill bit that both cleans the bottom hole and cleans cone inserts.
