摘要： A liquid reconditioning system including first and second storage tanks for storing reconditioned liquid and liquid to be reconditioned, respectively. Reconditioned liquid is withdrawn from the first storage tank for use, as required, and returned to the second storage tank. A filter is connected to receive liquid withdrawn from the second tank to filter that liquid and transfer it to the first tank. The present invention detects a condition representative of filter blinding and responds to that condition to automatically regenerate the filter. In a preferred embodiment, the filter is a diatomite filter with filter regeneration being accomplished by mechanical diatomite displacement. A valve at the filter output closes that output during diatomite displacement and then sequentially connects the filter output to the second storage tank, for a predetermined period, and then to the first storage tank. Filter blinding may be detected by monitoring the liquid level in the first storage tank, the decrease in that liquid level indicating that the liquid flow through the filter is below that necessary to maintain an adequate supply for use. Alternatively, a flow meter may be employed at the output of the filter to assure that the flow through the filter is adequate to satisfy the usage requirements.
摘要翻译： 一种液体修复系统，包括分别用于储存经过翻新的液体和液体的第一和第二储罐。 根据需要，将再生液体从第一储罐中取出使用，并返回到第二储罐。 连接过滤器以接收从第二罐排出的液体以过滤该液体并将其转移到第一罐。 本发明检测代表过滤器盲目的状况，并响应该条件自动再生过滤器。 在优选实施方案中，过滤器是具有过滤器再生的硅藻土过滤器，其通过机械硅藻土移位来实现。 过滤器输出处的阀关闭硅藻土位移期间的输出，然后将过滤器输出依次连接到第二储罐一段预定的时间，然后再连接到第一储罐。 可以通过监测第一储罐中的液位来检测过滤器盲孔，该液面的减少表明流过过滤器的液体流量低于维持足够的供应量所需的液体流量。 或者，可以在过滤器的输出处采用流量计，以确保通过过滤器的流量足以满足使用要求。

摘要： A trailer support wheel assembly having a wishbone frame pivotally connected to the trailer frame at two rear mounting points and adjustably connected to the trailer frame at a single forward point. A resilient suspension assembly and spindle is contained by the wishbone frame assembly, and the spindle is further connected to one or more wheels which may be lowered into contact with the ground. The wishbone frame assembly may be adjustably positioned to permit the wheels to carry a greater or lesser load portion of the trailer as it is connected to a vehicle.

摘要： A power supply assembly for converting input power into desired output power comprises a plurality of printed circuit boards each having oppositely facing front and back major surfaces. The back major surfaces of the first and second circuit boards are substantially devoid of the electrical components. The power supply assembly further includes a heat sink disposed adjacent to the first and the second circuit boards, an electrically conducting spline member, which is disposed between the first and second circuit boards, being attached to the heat sink, and a plurality of connectors electrically connecting the first and second circuit boards.

摘要： A compact document reading station for transporting a document and sensing indicia carried on the document. First and second substantially identical box-like housing halves, each with four sides, a generally closed bottom and an open top, contain an in-line arrangement of a motor and a drive roller powered by that motor as well as an off-set driven pinch roller. The rollers which partially extend through openings formed through the generally closed bottom and the housing halves are juxtaposed and connected together with the drive roller of one housing half cooperating with the driven pinch roller of the other housing half. Located between the roller openings in the bottom of each housing half is a row of spaced-apart apertures through which a portion of a plurality of photo-optic transducing head assemblies project. Each such transducing head assembly includes a hybrid circuit card having terminal pins which mate with connectors disposed on printed circuit cards which, when in place, act as covers for the open tops of the housing halves. One printed circuit card includes the components and interconnections for controlling the operation of the dual drive motors, and the other card includes the components and interconnections comprising the reading electronics which carry the data from the light-sensing elements of the plural photo-optic transducing heads.

摘要： A load frame which mounts on a trailer between the trailer hitch connection and the trailer frame front cross member. The load frame is a wishbone-shaped structural unit which mounts to the trailer frame front cross member with a pivoting saddle on the two rear legs of the wishbone. The load frame includes a spindle mount connected to a wheel assembly and a retracting arm for engaging a retracting apparatus to adjust the relationship between the wheel assembly and the trailer frame. The spindle mount includes a suspension mechanism and a pivoting connection for the wheel assembly. The wheel assembly includes a spindle member which is slidably and rotatably attached to the spindle mount. A tire is rotatably attached to the wheel assembly. The tire extends downwardly from the spindle mount to roll along the ground and support a portion of the tongue weight of the trailer.
