    Abstract: An ADC system includes a sigma-delta modulator that receives an analog input and provides a first digital output and an analog output. An ADC, coupled to the sigma-delta modulator, receives the analog output as an input and provides a second digital output. A digital processor, coupled to the sigma-delta modulator and the ADC, receives the first and second digital outputs and provides a digital representation of the analog input.

    Abstract: A paperboard sheet has a longitudinal scoreline defining a narrow flap portion on one side thereof and a body potion on the other side. The sheet is packaged flat together with a set of tabbed dividers thereby protecting the dividers. With the sheet and dividers removed from the packaging, the flap portion is folded up ninety degrees on the scoreline to define a guide tray. The guide tray is inserted into a printer feed tray and the set of tabbed dividers is placed on the body portion with the tabs thereof abutting the upturned flap portion, and the feed tray guides adjusted. The flap guides the dividers as they are fed into the printer, preventing skewing thereof. Guide tray instructions are conveniently printed on the paperboard sheet. The guide tray can be used for guiding sheets, other than tabbed dividers, which have irregular longitudinal edges.

    Abstract translation: 纸板具有在其一侧上限定窄翼片部分的纵向刻痕线和另一侧上的主体部分。 该片材与一组标签分隔件一起平坦包装，从而保护分隔件。 当从包装中取出片材和分隔物时，折片部分在刻痕线上折叠九十度以限定导向盘。 引导托盘插入打印机进给托盘中，并且一组标签分隔件被放置在主体部分上，其突片邻接向上的折翼部分，并且进给托盘引导件被调节。 分隔件在进给到打印机时引导分隔件，防止其偏斜。 导纸盘说明书方便地印在纸板上。 引导托盘可用于引导除了具有不规则纵向边缘的标签分隔件之外的片材。

    Abstract: An assembly for creating laminated cards for printing by a laser printer has a backing sheet. The backing sheet has a first side with a release coating, and a second side with a printable surface. The assembly also has a card which has been cut from the backing sheet. A lamination sheet adhesively adheres to the first side of the backing sheet and to the cut card. A lamination strip which has been cut from the lamination sheet has a first portion which adheres to and covers one surface of the card. The lamination strip also has an integral second portion which adheres to the backing sheet adjacent to the cut card. The lamination strip maintains the cut card in the same position relative to the backing sheet that the card had prior to being cut. The assembly has a substantially constant thickness and substantially flat upper and lower surfaces so that the assembly can pass through a complex paper path without jamming. A method for creating laminated cards from such an assembly has several steps. A user feeds the assembly into a printer. The printer prints onto the surface of the card. The user removes the card from off the assembly and peels the lamination strip from the assembly. The user then folds the lamination strip to cover the printing surface of the card.

    Abstract translation: 用于制造用于由激光打印机打印的层压卡片的组件具有背衬片。 背衬片具有带有剥离涂层的第一侧面和具有可印刷表面的第二侧面。 组件还具有已经从背衬片材切割的卡片。 层压片粘附到背衬片的第一侧和切割卡片上。 已经从层压片切割的层压带具有粘附并覆盖卡的一个表面的第一部分。 层压带还具有一体的第二部分，其附着在与切割卡片相邻的背衬片材上。 层压条将切割卡片相对于卡片在切割前的背衬片材保持在相同的位置。 组件具有基本恒定的厚度和基本上平坦的上表面和下表面，使得组件可以通过复杂的纸路径而不会卡住。 从这种组件制造层压卡的方法有几个步骤。 用户将组件送入打印机。 打印机打印到卡的表面上。 用户将卡从组件中取出，并从组件剥离层压条。 然后，使用者折叠层压条以覆盖卡的打印表面。

    Abstract: A corrugated paper display stacker having a plurality of vertically arranged springs and upwardly biased pivoted trays secured to a back panel. A double acting torsion spring having hooks on protruding fingers that are inserted into the fluting of the tray and a stablizing U-shape loop on the other side of the spring maintain each of the trays in a vertical position when not loaded with merchandise. The torsion spring is held to the back panel by securing means in the form of a dowel.

    Abstract: A skewed end assembly for connection to an arch culvert structure is provided. The assembly may generally include an arch-shaped inner skewed panel and a wedge member having a partially arch-shaped profile adapted for engagement with the inner skewed panel. The inner skewed panel may include a ledge that may include a plurality of threaded anchors. The wedge member may include a lip adapted for engagement with the ledge. The lip may include a plurality of apertures for receiving a plurality of threaded connectors adapted for threadable engagement with the corresponding threaded anchors in the ledge. Two assemblies, each comprising an inner skewed panel and a wedge member, are placed at opposed ends of an arch-shaped bridge or culvert structure to provide generally co-planar skewed ends to the structure such that it may be positioned at an angle in relation to a roadway such that the skewed ends are generally parallel to the roadway.
