Patent number: 10393276Abstract: An improvement in a valve block for use with diaphragm-based valves is disclosed. The valve block includes a fluid-transfer plate with multiple small-diameter inlet bores connecting to a common inlet channel, and multiple small-diameter outlet bores connecting to a common outlet channel. The valve block also includes a pressure plate and diaphragm aligned and connected to the fluid-transfer plate in a way that allows pressurized material in the pressure plate to control the state of the channels formed by the inlet and outlet bores. The sizing and number of bores is optimized to accommodate high fluid flow rates, control fluid pressure, and enhance reliability.Type: GrantFiled: December 10, 2014Date of Patent: August 27, 2019Assignee: SEMBA BIOSCIENCES, INC.Inventors: Brian A. Harbrecht, Robert Charles Mierendorf, Scott G. Manke

Patent number: 9068662Abstract: A device to enhance sealing is provided. The device includes a body and a pressure cup. The pressure cup includes a channel, a first pressure channel, and a second pressure channel. The channel is formed in a surface of the body to surround a first portion of the surface. The channel is configured to hold an o-ring. The first pressure channel extends through the body and opens into the first portion of the surface. The second pressure channel extends through the body and opens into the channel. Pneumatic pressure within the second pressure channel is controlled to hold the o-ring in the channel when a second pressure within the first pressure channel changes.Type: GrantFiled: October 30, 2013Date of Patent: June 30, 2015Assignee: Semba Biosciences, Inc.Inventors: Andrew Paul Wilke, Robert Charles Mierendorf, Anthony Charles Grabski, Cunjiang Cheng

Patent number: 8636259Abstract: A carriage holder for support of an apparatus includes identical upper and lower support plates having on their outer edge a number of indentations corresponding to the number of apparatus to be supported, said indentations providing aligned radial horizontal grasping surfaces on one side of said apparatus. The carriage holder also includes a series of vertical spring pivot pins joining said upper and lower support plates, adjacent to each said indentation, each such pin bearing a torsion spring loaded retractable clamp member to provide grasping surfaces in retracted position opposite to the grasping surfaces of said indentations. The carriage holder also includes an unobstructed aperture in each of said aligned support plates for mounting said carriage holder on a shaft. The carriage holder further includes a locking mechanism to hold said carriage in a fixed position on the shaft.Type: GrantFiled: July 13, 2011Date of Patent: January 28, 2014Assignee: Semba Biosciences, Inc.Inventors: Scott G.
