Abstract: Techniques for in-person electronic signatures using mobile devices are disclosed. A method includes generating a code corresponding to an electronic document. The code may include a device identifier associated with a first device. The method may include receiving a request from a second device that scanned the code. The method may include receiving metadata received in response to input at the second device in response to determining that a proximity of the first device to the second device satisfies a threshold using network information. The method may include modifying the electronic document based on the metadata.

Abstract: Feather-indented knives and related methods. A feather-indented knife may be produced by a process that involves flat grinding a blade, creating texture and beveling with computerized numeric control (CNC) grinding, hardening the steel with a quench process heat treatment, and grinding the blade with CNC to produce a desired bevel thinness. The knife includes a plurality of lower and upper feather indentations that converge at a middle of the blade and point toward the handle of the knife. The feather indentations have a variable diameter depending on their position along the blade, and they enable sufficient air to enter the space between the blade and the food during a downward or rearward stroke of the knife to separate the food from the blade while cutting.

Abstract: A steel with a carbon content of less than 0.3 percent by weight is used for steel-based components which are subjected to hot forming. A predominantly lower bainite structure is achieved by controlled cooling. The advantage is that components, such as truck steering knuckles, which are forged at temperatures of up to about 1300.degree. C., no longer need be subjected to annealing or tempering after cooling in order to possess good ductility in addition to high strength.

Abstract: A cylinder head produced having partially reinforced cylinder heads, particularly of internal combustion engines, providing a preformed workpiece of a predetermined material composition, and casting on said workpiece a material capable of producing a bond with said predetermined material composition for forming a positive connection between said workpiece and said casting material, including a cast portion; and a preformed workpiece positively connected to said cast portion for reinforcing those parts of said cast portion which are highly stressed during use.

Abstract: A method of producing partially reinforced cylinder heads, including casting a material on a preformed workpiece with special material properties, whereby the casting material produces a mechanical and/or metallic bond with the preformed workpiece in the transition phase of the two materials, and cylinder head made according to this process.

Abstract: Method and device to prevent valve bridge cracks in the cylinder head of internal combustion engines. The cylinder head is exposed to compressive stresses acting radially inwards in the region between the valve seats and a surface facing the combustion chamber by a circular ring shrink fitted on the cylinder head in the region of the valve seats and concentrically to the axis of a cylinder.
