Abstract: A milking device for milking a dairy animal is provided with milking mechanism, a control system, a milk pipeline for transporting the milk from the milking mechanism to a milk tank, a milk filter and a cleaning device. The cleaning device includes at least one cleaning fluid holder, a heating device for heating cleaning fluid in the cleaning fluid holder, an additive storage holder for additive, an additive adding device for controlled addition of the additive to cleaning fluid, and a valve system for regulating flows of cleaning fluid and additive through the milking device. The cleaning device is configured for carrying out a cleaning cycle of the milking device with a prerinse with cold or tepid water, a hot rinse with heated water and an acidic or basic additive, a postrinse, and at least between the hot rinse and the postrinse, a counterflow cleaning step by passing cleaning fluid in counterflow through the milk filter. Thus, a milking device is provided that can be cleaned automatically as a whole including the milk filter. In particular, because the counterflow cleansing takes place after the hot rinse step, there is better removal of dirt and milk residues that are softened thereby, in particular from the milk filter.

Abstract: A valve assembly is disclosed for use in conjunction with a replaceable filter cartridge system. The valve assembly includes a head member having an interior valve chamber defining a central axis, and inlet and outlet passages extending parallel to and communicating with the interior valve chamber. The valve assembly further includes a valve member having an inlet path and an outlet path, adapted for rotation within the interior valve chamber of the head member between a filter position wherein the inlet path of the valve member is in communication with the inlet passage of the head member and a bypass position wherein the inlet path of the valve member is out of communication with the inlet passage of the head member. The valve assembly further includes a seal member seated in an upper surface of the valve member and positioned to seal against an opposing surface of the interior valve chamber. The seal member sealingly isolates untreated and treated fluid streams flowing through the inlet and outlet paths of the valve member, respectively, when the valve member is in the filter position, and sealingly isolates the inlet and outlet passages of the head member from the atmosphere when the valve member is in the bypass position to permit fluid to flow therebetween.

Abstract: An improved continuous large area polymer filter employs a single valve to control molten polymer flow into and out from at least two but preferably three or more filter assemblies. In a neutral position the valve apportions flow equally to each of the filter assemblies. When filters in any one of the assemblies becomes clogged and requires cleaning or replacement, the valve is repositioned to prevent flow into and out from the clogged assembly while continuing to apportion flow among the remaining assemblies. A small amount of polymer is bled from the selected assembly to effect depressurization and the assembly is removed, restored to function and replaced. The valve is repositioned to allow a slow bleeding of polymer into the restored assembly and the bleed valve is opened to allow air and air entrapped polymer to be removed from the assembly before returning it to service. When the bleed valve flow has stabilized the valve is once again repositioned to allow full flow into and out from the serviced assembly and to apportion flow to each assembly. The valve has mechanical stops to prevent flow from being blocked to all of the assemblies simultaneously and a shield is attached to the valve to prevent access to operating assemblies. The shape of the filter cavities is tapered toward the output end to reduce the volume of molten polymer entrapped stagnantly between the cavity and the filter therein.

Abstract translation: 改进的连续大面积聚合物过滤器采用单个阀来控制熔融聚合物流入和流出至少两个但优选三个或更多个过滤组件。 在中性位置，阀分配平均流向每个过滤器组件。 当任何一个组件中的过滤器堵塞并需要清洁或更换时，阀被重新定位，以防止流入和流出阻塞的组件，同时继续在其余组件之间分配流量。 从所选择的组件中排出少量聚合物以实现减压，并且组装被去除，恢复功能并被替换。 阀被重新定位以允许聚合物慢速渗透到恢复的组件中，并且泄放阀打开以允许空气和空气夹带的聚合物在返回使用之前从组件中移出。 当泄放阀流量已经稳定时，阀再次重新定位，以允许完全流入和流出服务组件，并将流量分配给每个组件。 阀具有机械止动件，以防止流动同时被阻塞到所有组件，并且屏蔽件附接到阀门以防止进入操作组件。 过滤腔的形状朝向输出端逐渐变细，以减少熔融聚合物在空腔和过滤器之间滞留的体积。

Abstract: A water filtering system for connection to at least one water supply to be filtered including a filter tank containing cartridge-type filter media with the tank being especially configured to provide an evenly distributed water flow through the filter media for efficient water filtration. The system further includes a special plumbing system and controls therefore for establishing a two stage filter cleaning operation wherein water is impingingly directed onto the filter media for flushing of the filter media and the filter tank in the first stage of the filter cleaning operation and water is directed through the filter media in a backwash direction in the second stage of the filter cleaning operation. The controls may be automatic for switching the system from water filtering operation to filter cleaning operation at pre-determined time intervals, or whenever the filter media becomes dirty, and for switching back and forth between the two stages of the filter cleaning operation whenever the system is in the filter cleaning operation.
