  • Publication number: 20180326138
    Abstract: A dialysate mixing machine may be configured to make dialysate on demand using, among other things, a plurality of concentrates in solid tablet form. For example, a prescription may be received by the dialysate mixing machine indicating the particular chemical constituents and amounts of each chemical constituent to be included in the dialysate. Based on the prescription, the dialysate mixing machine can determine the number of tablets required for each chemical constituent (and, e.g., the required amounts of other chemical constituents that are not in tablet form). The tablets are automatically dispensed and mixed with purified water, bicarbonate, and sodium chloride in a mixing chamber to produce the dialysate according to the prescription. The dialysate mixing machine may be used with and/or coupled to a dialysis machine (e.g., a hemodialysis (HD) machine designed for home use) to provide the dialysate on demand for a dialysis treatment.

  • Patent number: 10099243
    Abstract: An adhesive dispensing device includes a heater unit for melting adhesive, a fill system communicating with a receiving space for feeding the heater unit, and a reservoir for receiving melted adhesive from the heater unit. The dispensing device also includes a capacitive level sensor located along a sidewall of the receiving space such that the level of adhesive in the receiving space can be detected by sensing the difference in dielectric capacitance where the adhesive is located compared to where air acts as the dielectric. The size of the driven electrode produces a broader sensing window capable of generating multiple control signals corresponding to different fill levels of adhesive. The receiving space and reservoir are minimized in size so that adhesive is not held at elevated temperatures long enough to char or degrade.

  • Publication number: 20180238397
    Abstract: A motor vehicle clutch assembly is provided. The motor vehicle clutch assembly includes a radially extending section including an abutment surface; a clutch pack including a first clutch plate and a separator plate; an axially movable piston for engaging the clutch pack; and elastic connectors connecting the separator plate to the radially extending section. The elastic connectors preload the separator plate away from the abutment surface. The motor vehicle clutch assembly also includes a stop arranged for contacting the separator plate to limit axial movement of the separator plate away from the abutment surface. The stop is an axial distance away from the abutment surface such that the separator plate is forceable by the elastic connectors against the stop to provide clearance such that the first clutch plate is movable away from the abutment surface. A method of forming a motor vehicle clutch assembly is also provided.

  • Patent number: 9957118
    Abstract: Methods for storing and moving adhesive particulate to an adhesive melter are disclosed. An interior space of a supply hopper is filled with adhesive particulate. A transfer pump is actuated to generate a vacuum at an inlet of the transfer pump to actuate removal of the adhesive particulate from the supply hopper. A consistent minimized depth of the adhesive particulate located directly above the inlet is maintained with a shroud located within the interior space of the supply hopper. In addition, adhesive particulate can be received in an interior space of a container. An open space is maintained within the interior space of the container proximate the pump inlet, where the open space entrains gas to be drawn by the transfer pump. The transfer pump can be actuated to generate a vacuum at the pump inlet to cause removal of the adhesive particulate from the container.

  • Patent number: 9889996
    Abstract: An adhesive melter and a method for operating the adhesive melter enables predictive maintenance of an exhaust air filter used to remove pressurized air flow that delivers solid adhesive particulate from a fill system into the melter. To this end, the fill system repeatedly actuates to refill a receiving space, and a controller monitors a duration of each fill system cycle. When changes in a calculated average duration of a plurality of fill system cycles exceed a maintenance threshold, an alert is emitted at a user interface to prompt maintenance or replacement of the exhaust air filter before a complete shutdown of the fill system is caused by clogging of the exhaust air filter. Consequently, unplanned downtimes caused by clogged exhaust air filters in the adhesive melter can be minimized, regardless of any variable conditions occurring at the melter.

  • Patent number: 9555438
    Abstract: A transfer pump for moving pellets of adhesive includes a pump housing with an adhesive inlet coupled to a supply hopper, an adhesive outlet coupled to an outlet hose, and an adhesive passage extending between the adhesive inlet and the adhesive outlet. A first air nozzle communicates with the adhesive passage adjacent the adhesive inlet and expels a first air jet that pushes pellets of adhesive through the adhesive passage. A second air nozzle communicates with the adhesive passage between the adhesive inlet and the adhesive outlet and expels a plurality of second air jets that draw pellets of adhesive through the adhesive passage by a vacuum force. The first and second air nozzles prevent clogging of pellets in the adhesive passage and enable movement of larger pellets than either air nozzle individually.

  • Patent number: 9540189
    Abstract: An adhesive dispensing device includes a heater unit for melting adhesive material, a receiving space for feeding the heater unit, and a cyclonic separator unit for delivering adhesive pellets to the receiving space. The cyclonic separator unit includes a tangential inlet pipe proximate to a top end of a generally cylindrical pipe, which is connected to the receiving space at an open bottom end. The tangential or spiral flow of air and adhesive pellets generated through the cyclonic separator unit reduces the speed of the air and adhesive pellets to avoid splashing of molten adhesive material while maintaining enough speed to avoid adhesive build up on the generally cylindrical pipe.
