Publication number: 20230081213Abstract: A rebar cage assembly system, a modular jig system and method for forming a rebar cage are disclosed. The rebar cage assembly system includes a modular jig for forming a rebar cage. The modular jig includes a fixture base, and a plurality of jig subcomponents. The jig subcomponents each having a jig attachment feature and a rebar retention feature. The rebar retention feature is configured to detachably receive rebar segments. The plurality of jig subcomponents are customizably arrangeable on the fixture base to form a modular jig to cooperatively position rebar segments in the rebar retention features. The rebar cage assembly system further includes a robotic system having a first robot and second robot and a plurality of rebar segments. The first robot is arranged and disposed to independently retrieve and position jig subcomponents and rebar segments. The second robot is arranged and disposed to join rebar segments to form a rebar cage.Type: ApplicationFiled: October 17, 2019Publication date: March 16, 2023Inventors: Daniel BLANK, Ian M.

Patent number: 11451022Abstract: An explosion-protected device (1) comprises a deformable interior body (20) that comprises at least one line channel (30, 31) extending along a longitudinal axis (L) through the interior body (20) for a line. The line extends through the at least one line channel (30, 31). The interior body (20) is encompassed by a housing (2). The housing (2) is divided into an incoming section (3), an outgoing section (4) as well as a middle section (5) disposed between the incoming section (3) and the outgoing section (4). A spring element (25) is provided which is disposed in the middle section (5) and exerts pressure onto the interior body (20).Type: GrantFiled: March 3, 2021Date of Patent: September 20, 2022Assignee: Pepperl + Fuchs SEInventor: Michael Hellmann

Patent number: 9290832Abstract: The invention relates to a cold-rolled carbon steel comprising (in % by weight) C 0.63-0.85%, max. 0.40% Si, 0.20-0.90% Mn, max. 0.035% P, max. 0.035% S, max. 0.060% Al, max. 0.40% Cr, 0.003-0.010% N, preferably 0.005-0.008%, and a maximum of 0.12% of at least one micro-alloying element, the remainder being iron and steel production-related pollutants. Possible micro-alloying elements are Ti, Nb, V and optionally Zr. A carbon steel of the type is cold-rolled into texture-rolled strip steel with a high cold reduction degree and can be used in particular as a material for coiling springs or other components having spring properties.Type: GrantFiled: February 25, 2010Date of Patent: March 22, 2016Assignee: C.D.

Patent number: 8652396Abstract: A method continuously creates a bainite structure in a carbon steel, especially a strip steel by austenitizing the carbon steel; introducing the austenitized carbon steel into a bath containing a quenching agent; adjusting the carbon steel to the transformation temperature for bainite and maintaining the transformation temperature for a certain period of time; and then cooling the carbon steel. The carbon steel stays in the bath until a defined percentage of the bainite structure relative to the total structure of the carbon steel has formed. Residues of the quenching agent are removed from the surface of the carbon steel by blowing the same off when the carbon steel is discharged from the bath, and the remaining structure components of the carbon steel are then transformed into bainite in an isothermal tempering station without deflecting the carbon steel at all.Type: GrantFiled: April 18, 2011Date of Patent: February 18, 2014Assignees: C.D.

Patent number: 7586068Abstract: A device and method are provided for protecting the inside of a microwave oven from food splattering during cooking. The device is made of breathable food grade paper, is a truncated cone in shape with a pleated side wall for rigidity and at least one reinforcing structure on a top surface. Top surface reinforcement may be one or more folded paper reinforcement bars or folded paper reinforcement members, shaped as circles, squares, or any other convenient shape. Reinforcement bars may be radial across the top surface or nonradial, and may be linear or curvilinear. The food shield device is made by conventional paper die stamping methods.Type: GrantFiled: May 19, 2006Date of Patent: September 8, 2009Inventors: Peter Shaw, Michael Hellmann

Publication number: 20090139616Abstract: The invention relates to a method for continuously creating a bainite structure in a carbon steel, especially a strip steel. The method comprises the following steps: the carbon steel (1) is austenitized (3) at a temperature exceeding the austenitizing temperature; the austenitized carbon steel (1) is introduced into a bath (2) containing a quenching agent (21) in order to cool the carbon steel (1) to a temperature lying below the austenitizing temperature; the carbon steel (1) is adjusted to the transformation temperature for bainite and is maintained (13) at the transformation temperature for a certain period of time; and the carbon steel is then cooled (17).Type: ApplicationFiled: October 31, 2006Publication date: June 4, 2009Inventors: Werner Kaiser, Heinz Hofinghoff, Hans-Toni Junius, Michael Hellmann, Peter Ebner, Heribert Lochner
