Abstract: A spark plug housing. The spark plug housing includes an inner side, an outer side, and a longitudinal axis, which extends from an end of the spark plug housing facing toward the combustion chamber up to an end of the spark plug housing facing away from the combustion chamber. The spark plug housing includes a circumferential shoulder on its inner side, which is designed so that a spark plug insulator rests thereon, and a corrosion protection layer on its inner side, which is formed on a section of the inner side of the spark plug housing, the section extending from the end of the spark plug housing facing toward the combustion chamber to at least over the shoulder and along the inner circumference of the spark plug housing.

Abstract: An injector component of an injector for introducing a fluid is described as including a base body, a coating on at least one first end face of the base body, the coating having a maximum, which lies on an outer half of the base body, and an outer lateral surface of the base body does not have any coating.

Abstract: A coating device for coating components, in particular for nickel-plating spark plug housings. The coating device includes: a housing having an outer anode that is designed to receive the component, an inner anode that can be introduced into a through-opening of the component, and a voltage-generating device, the voltage-generating device being designed to generate a first voltage between the outer anode and the component, as well as a second voltage between the inner anode and the component. The housing has an inlet and an outlet for introducing and discharging a process medium into or out of the housing.

Abstract: A pretreatment method for pretreating components, which are each formed of at least two different materials, prior to a coating process. The pretreatment method includes the steps: alkaline degreasing; chemical pickling in a first pickling medium; anodic pickling in a second pickling medium; and cathodic degreasing.

Abstract: The present invention relates to a method for purifying raw dinitrotoluenes resulting from dinitration of toluene in the presence of a nitric acid/sulfuric acid/nitrating acid mixture, and a device or plant for performing the method, and a corresponding production plant for producing dinitrotoluene, characterized in that (a) the raw dinitrotoluenes are first subjected to a wash with at least one washing medium after separation of the nitrating acid mixture, followed by a separation of the washing medium; and that (b) subsequently the washed dinitrotoluenes resulting from method step (a) are subjected to stripping (stripping gas treatment) with at least one gas (stripping gas).

Abstract: An aircraft fuselage including an outer skin that is stiffened by way of a backing structure and that delimits at least one passenger cabin and one cargo hold. In the vertical direction of the fuselage, the cargo hold is arranged below the passenger cabin. The backing structure in the cargo hold above a cargo-hold floor framework comprises at least two lateral quasi-joints, and below the cargo-hold floor framework comprises at least one further quasi-joint. In the cargo hold, in the longitudinal direction of the fuselage, a multitude of energy absorption devices, arranged one behind the other and acting in the transverse direction of the fuselage, are arranged for absorbing tensile loads.

Abstract: A refrigerator includes a multiple slide crisper system. More specifically, a universal crisper pan and support frame for a refrigerator can be used with various, distinct glide arrangements, including friction, roller or ball bearing glides. For frictional sliding movement, crisper pan side walls slide directly upon molded inner rails on the frame. With the roller system, various rollers are fitted to a rear portion of the crisper pan through the use of pins, while commensurate rollers are mounted at front portions of the frame. When using ball bearing glides for a precision slide support, the glides are preferably mounted to the support frame at an acute angle to the axis of travel of the friction and roller glide systems.

Abstract: An ice and water dispenser for refrigerator doors is provided that includes an ice dispensing actuator pad that causes dispenser to deliver ice when activated. The dispenser also includes a water dispensing lever that causes the dispenser to deliver water when pushed. The ice and water dispenser includes a control panel that allows the user to control the dispensing operation, such as whether to dispense crushed or cube ice. Because of the arrangement of the ice and water dispensing actuators, the user can insert a glass into the dispensing cavity and dispense both ice and water simultaneously. Further, because of the arrangement of the ice and water dispensing actuators, the user can fill oversize cups, water bottles, or pitchers without having to awkwardly reach around the cup to manually activate the water dispensing lever or push the ice dispensing actuator.

Abstract: A system for determining a musical modulation from a source key to a target key, such that the source key and the target key are selected from a cycle of musical keys. The system includes a relational tool and a bridging tool. The relational tool is capable of determining a primary modulation reference correlated to the displacement between the source key and the target key. The bridging tool includes a selected set of at least one bridge. The selected set is correlated to the primary modulation reference. The present invention also has a method for determining a musical modulation from a source key to a target key, such that the source key and the target key are selected from a cycle of musical keys.
