Processing Method and Processing System for Wire Mesh Abnormality and Electronic Device
US Patent 20250018606
Published January 16, 2025
Inventors: Haoming Zhang, Xuzhou Yang, Rui Wu, Chen Wei, Pengzhan Zhao (Tianjin, China)
Assignee: TCL Zhonguan Renewable Energy Technology Co., Ltd. (Tianjin, China)

A processing method for wire mesh abnormality includes the steps of:

  1. Obtaining position heights of cutting wires in a wire mesh.
  2. Obtaining a jumping value of each cutting wire based on the vertical difference between the position heights of the cutting wires and the position height of a contact surface of the wire mesh and a workpiece.
  3. Obtaining a jumping curve of the wire mesh based on the obtained jumping values of the cutting wires.
  4. Determining whether the wire mesh is abnormal based on the jumping curve of the wire mesh.

The states of the wire mesh can be monitored in real time, predicting abnormalities in advance and allowing timely corrective actions. A processing system for wire mesh abnormality and an electronic device are also provided.

Hairpin Wire Motor Stator
US Patent 12191728
Published January 7, 2025
Inventors: Yu-Wei Chuang, Yao-Hsien Shao, Ji Dai (Taoyuan, Taiwan)
Assignee: Delta Electronics, Inc. (Taoyuan, Taiwan)

A hairpin stator includes an iron core with multiple slot positions and hairpin wires. The slot positions are located circumferentially around the iron core, forming adjacent slot-position layers radially. The iron core includes polar regions, each with phases and phase slots. Hairpin wires are arranged in the slot positions of the phase slots within the same phases of the polar regions, forming windings. The hairpin wires include transpolar hairpin wires. The span of the transpolar hairpin wires on the insertion side of the iron core equals a quotient obtained by dividing the total number of phase slots by the total number of polar regions, plus or minus one.

Tension Board for Straining Wire Netting
US Patent 12179320
Published December 31, 2024
Inventor: Ian Lowrey (Surry Hills, NSW, Australia)
Assignee: Wireman Pty Limited (Lane Cove West, NSW, Australia)

A tension board for straining net-style fencing materials includes:

  • A first plurality of spaced horizontal wires.
  • A second plurality of spaced vertical wires.

The tension board is an elongate member with a longitudinal axis and extent corresponding to the distance between the first and last horizontal wires. It has multiple wire grippers connected to the elongate member at spaced locations, each configured to releasably grasp a corresponding horizontal wire. This enables quick setup before straining and quick release once strained and tied off.

Telescoping Spring Retention Assembly for a Check Valve
US Patent 12181060
Published December 31, 2024
Inventors: Peter P. Bouchard (Ayer, MA, USA), Tyler Chase (Boscawen, NH, USA), David Michaud (Lawrence, MA, USA)
Assignee: Watts Regulator Co. (North Andover, MA, USA)

A valve assembly with a spring retention assembly includes:

  • An elongated cylinder portion with an open threaded end and a closed end.
  • An elongated piston portion with a free end and a threaded tab end configured to thread through the open threaded end, slideably captured in the cylinder portion.
  • A spring coupling the body and piston portions to provide a force urging them apart.

The closed end and free end are similarly shaped, allowing the spring retention assembly to be reversibly mounted to a valve member.

Coil Spring Jig, Coil Spring Manufacturing Method, and Coil Spring Testing Method
US Patent 12173767
Published December 24, 2024
Inventors: Hirokatsu Kameda (Hitachinaka, Japan), Toshihiro Ogawa (Kasugai, Japan), Shinji Kasatori, Atsushin Murakami, Hideki Kato, Kenji Nagaoka (Tokyo, Japan)
Assignees: Hitachi Astemo, Ltd. (Hitachinaka, Japan), Honda Motor Co., Ltd. (Tokyo, Japan)

A coil spring jig includes:

  • A spring support portion where one end of a coil spring can be placed.
  • Multiple displacement regulating portions extending along the coil spring’s axis from the spring support portion, capable of abutting against the coil spring’s outer surface and regulating radial displacement.
  • A lid portion supported by the displacement regulating portions, capable of keeping the coil spring compressed by sandwiching it with the spring support portion.

Spring System Having a Wide-Band Insulating Effect
US Patent 12157340
Published December 3, 2024
Inventors: Michael Steidl, Norbert Reinsperger, Robert Kempgen, Mandy Streifler (Berlin, Germany)
Assignee: Hasse & Wrede GmbH (Berlin, Germany)

A spring system for a vehicle includes:

  • A first spring/damper unit with a first stiffness and damping.
  • A second spring/damper unit with a second stiffness and damping.
  • An additional mass as a tuned-mass absorber coupled to at least one negative stiffness.

A vehicle with such a spring system and a method for adapting the stiffness of a spring system are provided.

Spring Structure for Mechanical Oil Pump
US Patent 12158206
Published December 3, 2024
Inventor: KyungChul Joe (Gyeonggi-do, South Korea)
Assignee: BorgWarner Inc. (Auburn Hills, MI, USA)

A torsion spring for an oil pump chain tensioner includes:

  • A second end connected to a leg through a hook bend.
  • An outer coil connected to the leg, with an outer circumference and inner circumference.
  • A first inner coil connected to the outer coil, with an outer circumference and inner circumference.
  • A second inner c-shaped coil connected to the first inner coil through a bend back loop, terminating in a first end.

The second inner coil’s outer circumference and the first inner coil’s inner circumference define a gap.

Balance Spring and Method for Manufacturing the Same
US Patent 12153380
Published November 26, 2024
Inventors: Marco Verardo (Les Bois, Switzerland), Christian Charbon (Chezard-St-Martin, Switzerland)
Assignee: Nivarox-FAR S.A. (Le Locle, Switzerland)

A balance spring intended for a timepiece balance with fixed inertia includes:

  • A core with lateral faces connecting an upper face to a lower face.
  • A coating on one of the lateral faces in one portion of the outer coil, including two layers: a first electrically conductive layer coated with a second outer layer made of ceramic or a combined electrically conductive ceramic layer.

A method of manufacturing this balance spring is also provided.
