Patents by Inventor Johan STENBECK

Johan STENBECK has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Pump, a homogenizer comprising said pump and a method for pumping a liquid product
    Patent number: 10100830
    Abstract: A membrane-based piston pump (400) is used for pumping a liquid product. The pump is provided with a device (426) for maintaining a pre-defined hydraulic fluid volume in the pump. The device includes an axle element (440) and a bushing element (432). A method for pumping a liquid product in a pump may use the membrane-based piston pump. A homogenizer may include the membrane-based piston pump.

  • Conductivity sensor, and a pump comprising such sensor
    Patent number: 10060429
    Abstract: A conductivity sensor is provided. The sensor comprises at least one electrode being embedded in a cylindrical non-conductive body such that one end of each one of the at least one electrode is exposed to a sample volume, wherein the sensor further comprises a support body to which the cylindrical body is engagable with, which support body comprises means for attaching said support body to a frame structure in a fluid tight manner.

  • Piston pump arrangement for hygienic processing applications
    Patent number: 10018192
    Abstract: A membrane arrangement to be placed between a product chamber and a hydraulic oil chamber is provided. The membrane arrangement comprises a first membrane and a second membrane. Between the membranes in a membrane interior space a marker liquid is placed. By using a sensor it can be detected when product or hydraulic oil enters the membrane interior space, which in turn means that a rupture of any of the two membranes may be detected in a reliable and cost efficient way.

  • A PISTON PUMP ARRANGEMENT FOR HYGIENIC PROCESSING APPLICATIONS
    Publication number: 20150345487
    Abstract: A membrane comprises a main body having a first side and a second side. The main body is made of an elastic material in order to forward a pressure e.g. formed by a piston. On the second side it is provided a coating made of plastic material such that the main body is not affected by cleaning agents, abrasive products or the like coming in contact with the second surface.
