Publication number: 20250114531Abstract: A syringe containing a high water content product and for use in a drug infusion system is provided. The syringe includes a plunger carrying front and rear o-rings made of a diene rubber compound such as chlorobutyl rubber or bromobutyl rubber to impart very low gas permeability characteristics to the o-rings. The plunger may be molded as a single part or in two parts. If molded as one part with radially-engaging mold portions, the seal glands in the plunger may include parting lines from the mold. If molded as two parts with axially-engaging mold portions, the front seal gland may include a sealing surface and under cut that has no parting line. The o-rings may be surface treated with a lubricant to improve sealing where the molding process gives rise to parting lines in the seal glands, which can result in leak paths on the ID of the o-rings. The o-rings provide a gas-tight sliding seal that can withstand temperature changes from ?25° C. to 40° C.Type: ApplicationFiled: May 10, 2024Publication date: April 10, 2025Inventors: Martin J. Gibler, Mark A. Bennett, Kenneth R. Waeber, Kenneth E. Hogue, Christoph L. Gillum, Patrick A. Harrell, David A. Parrott, Sean E. Mackey, Rajkumar V. Conjeevaram, Thomas Rebne, Bradley A.

Patent number: 10648596Abstract: In a method of assembling a conduit fitting, a conduit fitting is provided, including a first coupling member, a second coupling member, an internal conduit gripping device disposed between said first coupling member and said second coupling member, and an external deformable structure. The first coupling member is pulled up with the second coupling member on an end portion of a conduit to engage the external deformable structure with an external surface of one of the first and second coupling members. After engaging the external deformable structure with the external surface of one of the first and second coupling members, the first coupling member is further pulled up with the second coupling member to axially compress the external deformable structure, until an amount of torque required to continue pulling up the first coupling member increases to a predetermined torque. The predetermined torque corresponds to an initial pulled-up position in which the conduit gripping device grips and seals the conduit.Type: GrantFiled: February 8, 2018Date of Patent: May 12, 2020Assignee: SWAGELOK COMPANYInventors: Mark D. Bearer, Mark A. Bennett, John D. Karkosiak, Jeffrey Michael Rubinski, Peter C. Williams, Tobin Berry, Mark A. Clason, Eric M. Kvarda

Patent number: 10359134Abstract: A conduit fitting preassembly includes an annular fitting component and at least a first conduit gripping device. The annular fitting component has an interior wall extending axially from a forward end to a rearward end, and a first projection extending radially inward from the interior wall. The first conduit gripping device is received within the annular fitting component and includes a second projection extending radially outward of an outer surface of the first conduit gripping device. The first projection includes an outward tapered rear surface and the second projection includes an inward tapered front surface. The rear surface of the first projection is radially aligned with the front surface of the second projection, such that when the first conduit gripping device is in a forward-most position, the first projection interlocks with the second projection to prevent axial withdrawal of the first conduit gripping device from the annular fitting component.Type: GrantFiled: August 26, 2016Date of Patent: July 23, 2019Assignee: Swagelok CompanyInventors: Peter C.

Patent number: 10316998Abstract: A fitting for a tube or pipe capable of functioning a high pressures having a first fitting component adapted to receive the conduit end; a conduit gripping device such as a ferrule or ferrules and a second fitting component that can be joined to the first fitting component to cause the conduit gripping device to grip the conduit and seal when assembled. In one aspect of the invention, the first fitting component is constructed from a material that is softer than the material used to construct the second fitting component. An additional aspect of the invention include a retaining portion on the second fitting component that constrains the tube gripping device against pressure. The retaining portion can also be configured to retain the tube gripping device to the second fitting component prior to installation and in a finger-tight condition.Type: GrantFiled: December 14, 2016Date of Patent: June 11, 2019Assignee: Swagelok CompanyInventors: Peter C.

Patent number: 10275366Abstract: Systems and methods that facilitate protecting vehicle impact event data from overwrite include an electronic control unit (ECU) having a processor that records event data related to vehicle operation, a memory that stores the event data, and an electronic tool that communicates with the ECU and comprises a data locking module that sends a data lock signal to the ECU to lock the stored event data as locked data such that the stored event data cannot be overwritten. The ECU, in response to the data lock signal, stores the event data as locked data in a dedicated portion of the memory to preserve the event data for subsequent review.Type: GrantFiled: April 11, 2016Date of Patent: April 30, 2019Assignee: BENDIX COMMERCIAL VEHICLE SYSTEMS LLCInventors: Ananda Pandy, Mark A.

Patent number: 10272890Abstract: When a brake system on a commercial vehicle, lateral acceleration and/or yaw of the vehicle are monitored and compared to a first predetermined threshold. If the first predetermined threshold is exceeded, a precharge command is sent to the brake system to precharge one or more air chambers by temporarily deactivating a modulator valve and activating an antilock traction relay valve in order to charge the air chambers up to a level permitted by the modulator valve. Upon detecting a panic braking event, a command signal is sent to the brake system to release the precharged air to facilitate braking.Type: GrantFiled: June 7, 2017Date of Patent: April 30, 2019Assignee: BENDIX COMMERCIAL VEHICLE SYSTEMS LLCInventors: Timothy Carritte, Mark A.

Patent number: 10000194Abstract: Various embodiments of an apparatus and method for monitoring a brake operation are disclosed. In accordance with one aspect, the brake operation monitoring system comprises a plurality of wheel speed sensors, a brake demand sensor; a plurality of stability sensors and a controller. The controller comprises wheel speed ports; a brake demand port; stability sensor ports; a communication port for receiving a plurality of messages; and a processing unit comprising control logic. The control logic receives a brake demand signal, at least one stability signal indicative of the cornering of the vehicle, and individual wheel speeds. The control logic calculates a master value to compare to individual wheel speed signals if the brake demand signal indicates no braking.Type: GrantFiled: August 10, 2016Date of Patent: June 19, 2018Assignee: Bendix Commercial Vehicle Systems LLCInventor: Mark A Bennett
