Abstract: A relay, in particular for high-current operation, having at least one coil and a movable armature which by the magnetic flux generated in the at least one coil permits or interrupts a current flow via two main contact terminals and having a current-measuring instrument for measuring at least one current flowing via the main contact terminals by at least one Hall sensor has a device around the main contacts for aligning the magnetic flux with the Hall sensor or sensors.

Abstract: A twin-axle rail vehicle bogie with two extended wheel sets and bearings and a bogie frame on which the wheel sets are sprung. The load-bearing part of the bogie frame includes a bogie cross member to which are connected a first link for a first of the two wheel sets and a second link for the other. Both the first and second links have a first free end which is pivoted about an axis on the bogie cross-member. The first and second links have a second free end link to a main suspension system where the wheel set bearing is fitted at a point between the first and second free ends. Both links have an upper shank ending at the second free end and running substantially vertically, and the main suspension system is arranged in such a way that it exerts horizontally-acting spring forces on the second free end.

Abstract: An arrangement for an endless belt includes an endless belt having an inside adapted to be driven by a transport wheel and an outside. Elastic fingers are attached to the outside of the endless belt. The elastic fingers are substantially evenly spaced from one another. Each elastic finger has a free end and another end that constitutes a fastening point to the endless belt. Each elastic finger has a curved shape between the free end and the fastening point and presents a clamping region between the free end and the fastening point.

Abstract: An improved method of depositing borophosphosilicate glass (BPSG) on a substrate is disclosed. The improved method uses temperatures substantially lower than conventional and a volume ratio of oxygen to the total hydride content in the deposition mixture substantially higher than conventional. A BPSG film of increased purity is produced at a rate of deposition substantially faster than conventional procedures.

Abstract: A method of accurately terminating the coating of a substrate in an aqueous coating solution is disclosed. The method comprises removing the substrate into an organic displacement liquid which overlies the aqueous coating solution.

Abstract: A method and composition for the detection of microdefects in the surface layer of a substrate is disclosed. The composition utilizes dimethylsulfoxide as a primary solvent and a fluorescent organic compound which fluoresces principally in solution. The visibility of microdefects is enhanced by etching the substrate underlying them to form channels for the fluorescent compound.

Abstract: A selective chemical etchant solution for phosphosilicate glass includes a carboxylic acid, hydrogen fluoride and water. The invention is also a method for preferentially etching the phosphosilicate glass which comprises the step of immersing the glasses in the etchant solution of the invention.

Abstract: Shaped bulk glass is provided which has improved properties and in particular improved compressive strength. The improvement is obtained by plasma depositing a film of amorphous polymeric hydrogenated silicon-silicon nitride on the surface of the bulk glass.

Abstract: The addition of 2-ethyl-1-hexanol to an organometallic titanium compound dissolved in a diluent and optionally containing a lower aliphatic alcohol spreading modifier, produces a solution that can be sprayed onto a substrate and cured to form an antireflection titanium oxide coating having a refractive index of from about 2.0 to 2.2.

Abstract: A semiconductor device including a body of semiconductor material with a metallic conductor disposed thereon has a combination glass/low-temperature-(typically 300.degree. C) deposited Si.sub.w N.sub.x H.sub.y O.sub.z passivating overcoat with improved crack and corrosion resistance. This nitride is formed over the conductor, with the glass over the nitride.
