    • A system and method for conducting an inventory of tags, wherein each tag is assigned a Tag ID and a manufacturer number. Each tag can be attached to an item to take inventory of those items. A tag reader transmits a wake-up signal followed by at least one clock signal. Each tag increments a first tag count in response to the clock signals, and transmits the Tag ID assigned to the tag when the first tag count corresponds to the Tag ID assigned to the tag. The tag reader records the transmitted Tag IDs. When more than one tag transmits simultaneously, the tag stores the Tag ID in order to resolve the contention when the first read cycle is complete. In the second read cycle, the tag reader transmits the contended Tag ID followed by at least one clock signal. Each tag that contended for the transmitted Tag ID increments a second tag count in response to the clock signals, and transmits the manufacturer number assigned to the tag when the second tag count corresponds to the manufacturer number assigned to the tag. The tag reader records the transmitted Tag IDs, completing the inventory of the tags.
    • 用于进行标签库存的系统和方法,其中每个标签被分配标签ID和制造商编号。 每个标签都可以附加到一个物品上,以便对这些物品进行盘点。 标签读取器发送唤醒信号,后跟至少一个时钟信号。 每个标签响应于时钟信号递增第一标签计数,并且当第一标签计数对应于分配给标签的标签ID时,发送分配给标签的标签ID。 标签阅读器记录传输的标签ID。 当多个标签同时发送时,标签存储标签ID,以便在第一个读取周期完成时解决争用。 在第二读取周期中,标签读取器发送竞争的标签ID,后跟至少一个时钟信号。 针对发送的标签ID的每个标签响应于时钟信号增加第二标签计数,并且当第二标签计数对应于分配给标签的制造商号码时,发送分配给标签的制造商号码。 标签阅读器记录传输的标签ID,完成标签的清单。

    • The ridge preparation tool is adapted to be attached to a seed planter directly ahead of the trench-forming structure of the planter so as to skim off the crest of the ridge for the production of a clean, relatively narrow strip of prepared soil in which the trench-forming structure can operate effectively. The free-wheeling skimming disc of the tool is held at an oblique angle to the centerline of the planter and may be adjusted to increase or decrease the extent of side throw of the skimmed off materials by selectively raising or lowering an outwardly bent mounting arm that holds disc at its oblique angle. Raising or lowering the angled mounting arm causes the disc to cock inwardly or outwardly while maintaining the same oblique angle. The throw-adjusted disc can be returned to the same skimming depth by appropriate manipulation of a vertical adjustment unit associated with the tool.
    • 脊部制备工具适于在播种机的沟槽形成结构之前直接附着到种子播种机上,以便撇去脊的顶部以产生干净,相对较窄的预制土壤条带,其中 沟槽形成结构可以有效地运行。 工具的自由轮撇光盘与播种机的中心线保持倾斜的角度,并且可以通过选择性地升高或降低向外弯曲的安装臂来调节以减少脱模材料的侧面抛光的程度, 保持其倾斜角度的光盘。 提升或降低角度的安装臂会使盘向内或向外旋转,同时保持相同的倾斜角度。 通过适当地操纵与该工具相关联的垂直调节单元,投掷调整盘可以返回到相同的掠夺深度。

    • A tension leveler roll cleaning system which is incorporated in a tension leveler of a type having a work roll supported by backup rolls and includes a payout stand, a takeup stand, and a strip of fabric media which is guided about the backup rolls. The payout stand preferably is positioned upstream of the backup rolls and the takeup stand downstream of the backup rolls. The strip of fabric media extends between the payout stand and takeup stand, and is held against arcuate portions of the backup rolls by spacer plates which extend between the bearing plates supporting the work and backup rolls. The takeup stand includes a hydraulic motor which is actuated to recoil the strip material and draw it from the payout stand about the backup rolls. The strip material is mounted in coiled form on the payout stand and is recoiled into a coil for efficient disposal. In a preferred embodiment, the system includes a solvent delivery component which consists of a spray manifold, supplied by a source of solvent under pressure for depositing solvent on the media. Preferred solvents are kerosene, petroleum hydrocarbon and petroleum naphtha.
    • 张力矫直机辊清洁系统,其结合在具有由支承辊支撑的工作辊的类型的张力矫直机中,并且包括支撑架,卷取架和围绕支承辊引导的织物介质条。 支撑架优选地位于支撑辊的上游和支撑辊的下游的卷取架的上游。 织物介质条在支承架和卷取架之间延伸,并通过在支撑工件和支承辊的支承板之间延伸的间隔板保持在支承辊的弓形部分上。 卷取架包括液压马达,其被致动以回弹条带材料并将其从支撑架上绕支撑辊拉出。 带状材料以卷绕形式安装在支架上,并且被卷绕成线圈以进行有效处理。 在优选的实施方案中,该系统包括溶剂输送组分,其由喷雾歧管组成,其由在压力下的溶剂源供应以在介质上沉积溶剂。 优选的溶剂是煤油,石油烃和石脑油。

    • A mount is secured to an end of a cylindrical housing with a front side facing outward thereof. A knob is provided having a stem extending from one end and a gear secured to and extending radially outward from the end of the knob. An aperture is formed through the mount for receiving the stem of the knob with the knob located on the front side of the mount near one edge thereof. A generally cylindrical shaped face member has an inner side secured to the front side of the mount and an outer side facing outward thereof. The face member has an opening formed therethrough for receiving the knob and its gear such that the knob may be viewed from the opening from the outer side of the face member. The opening of the face member extends to one edge thereof such that a portion of the gear is accessable from the edge. An annular member is located around the face member and is supported by the face member for rotation in opposite directions relative to the face member. The annular member has gear teeth in mesh with the teeth of the gear of the knob for causing the knob gear and hence the knob to rotate when the annular member is rotated relative to the face member.A stop and a slot are provided on the annular member and face member respectively or vice versa for limiting rotation of the annular member in opposite directions relative to the face member.
