Reference electrodes for potentiometric measurement of pH and ion concentration typically use mercury calomel or silver/silver chloride element combined with a saturated solution of potassium chloride (KCl) for the development of a stable potential with respect to a sensing electrode when immersed in solution. The salt KCl is preferred because of it is almost equitransferent and thus minimizes the diffusion potential set up between the reference solution and the solution being tested. However, reference electrodes using concentrated solutions of KCl suffer a drawback, which is its propensity to develop a creeping salt discharge that rapidly covers surfaces with KCl crystals. This “salt creep” phenomenon appears to be unique to KCl; Salt creep is a major nuisance, particularly for reference electrodes used on semi-dry surfaces such as skin. It has been found that adding a secondary salt, such as sodium chloride on its own or with an evaporation inhibiting agent in selected ranges inhibits salt creep without adversely affecting the other properties of the reference solution.

An approach is provided for providing list-based exploration of mapping data. The list-based exploration platform causes, at least in part, an association of one or more features of a geographical area with one or more list objects. Next, the list-based exploration platform processes and/or facilitates a processing of location information associated with one or more map data items to group, to sort, or a combination thereof the one or more map data items into the one or more list objects. Then, the list-based exploration platform causes, at least in part, a rendering of at least one of the one or more list objects in a user interface, wherein the user interface includes one or more user interface elements for controlling a browsing of the one or more map data items in the at least one of the one or more list objects.

A data transmission cable for connection to mobile devices, which has at least two insulated conductors (1, 2) twisted together into a pair. The pair is enclosed by an electric shield (7) over which a jacket (13) made of an insulating material is applied. To preserve the function of the cable even if it is subject to frequently alternating bending and torsional stresses, the two conductors (1, 2) insulated with a solid unfoamed material are twisted together with two first strands (4, 5) made of a foamed insulating material to form a core (S). The core (S) is enclosed by a foil (6) made of a foamed insulating material, and the shield (7) formed around the first foil (6) has at least one metal strip that is made of an electrically well-conducting material and is formed into a closed tubular sleeve.

An electrical cable (K) has at least two strands (1) consisting of insulated conductors (2) stranded together. Insulation on the strands (1) consists of an inner layer in contact with the conductor, and which is softer than an outer layer. The strands (1) are surrounded by an inner sheathing (6). The cable (K) also has an electric shield (7) and an outer sheathing (8). A separator layer (5) is between the strands (1) and the inner sheathing (6), consisting of an inner layer (6a, 6b) fixedly joined together with an outer layer (6b). The inner layer (6a) facing the strands (1) is softer than the outer layer (6b), having an approximately circular peripheral surface and in firm contact with the separator layer (5) or the strands (1). The electric shield (7) consists of at least one essentially closed tubular metallic layer and a stranded layer and/or braiding of metallic wires in contact with the metallic layer.

An armor system and method for the interior of a structure to be protected wherein releasable fastener material is secured to an inside wall of the structure and at least a first armor panel includes, in one example, a spacer layer, a ceramic hard face layer behind the spacer layer, a ballistic material behind the ceramic energy absorber layer, an encapsulant about the spacer layer, the ceramic energy absorber layer, and the ballistic material. Releasable fastener material is on the encapsulant adjacent the spacer layer for mating the panel to the inside wall of the structure.

A flexible electric line for movable loads is specified which has at least two wires, in each case consisting of an electrical conductor and an insulation surrounding it, as stranded elements which are stranded around a core consisting of insulating material with dents extending in the longitudinal direction in which the stranded elements lie. In the core, a non-metallic tension- and compression-resistant carrier enclosed by a layer of insulating material is centrally arranged. The layer of insulating material consists of an impressible material remaining permanently elastic, which completely fills the internal interstices between the stranded elements, and it is surrounded by a sliding layer of a material having good sliding characteristics compared with the stranded elements.

An electrical conductor L is specified, which has a central core (1) and at least two layers which are arranged above the core (1) and are composed of electrically conductive individual wires, which are twisted around the core (1) in a first layer (2) and around the first layer (2) in a second layer (4). The individual wires of the first layer (2) are steel wires with an ultimate tensile strength of between 800 N/mm2 and 2000 N/mm2, and the individual wires of the second layer (4) are copper wires with an ultimate tensile strength of between 250 N/mm2 and 400 N/mm2. A wire composed of a soft-annealed copper with an ultimate tensile strength of at least 210 N/mm2 is used as the core (1). The lay length of the copper wires (5) is between 8×D and 18×D where D is the diameter of the conductor L over the second layer.
