Abstract: Several trim patterns are illustrated which are suited for use in high voltage, surge prone environments. The invention combines a block resistor with a simple scan cut and two or more plunge cuts to simply form a resistor. The resulting resistor is immune to adverse affects associated with current crowding and arcing, both known to have much adverse impact on the prior art.
Abstract: A process for de-icing roadways to which is applied a melting agent to lower the freezing point. In order to save melting agent (salt), the melt water running off the roadway is collected and re-used for de-icing purposes provided that its melting agent content is adequate. To implement the process, use is made of a device for de-icing roadways including, along the length of the roadway, components such as spray nozzles (34) to apply the melting agent and run-off channels (16) to divert the water into a drainage channel (18) connected to a collector channel in its cycle. According to the invention, the run-off channels (16) lead into at least one collector tank (20) which returns the adequately concentrated melt water to the spray nozzles (34) via a supply line (26).
Abstract: The rotor of a rotary position sensor mounts directly upon the rotary shaft to be sensed. The rotor prior to installation is retained in position by a pair of small protrusions extending from the rotor that cooperatively engage a pair of small indentations formed in a pair of supporting arms. During the installation process, the rotor is slipped onto the shaft and the protrusions are released from the engaged position. During operation of the position sensor, the rotor is free from direct contact with either the supporting arms or any other stationary part of the position sensor. Only the contactors engage the stationary components. This design eliminates the need for bearings and return springs prevalent in the prior art.
Abstract: A detachable fiber optic connector provides connection from an optical source or sink through a hermetic connection to a removable attached optical fiber. Ferrules and a split ring are used for alignment. A variety of alternative embodiments are illustrated for providing coupling force between the ferrules and retaining forces to prevent movement of the connection during movement of the fiber relative to the optical source or sink. These detachable fiber optic connectors provide great benefit when combined with hermetic packaging.

Abstract: An optoelectronic subassembly is illustrated which ensures the alignment of multiple optoelectronic devices without special assembly process. The optoelectronic devices are mounted upon specially designed sub-carriers which may be used to test the devices prior to completing the subassembly. The subassembly improves yields of complex optoelectronic systems and lowers resultant production costs.
Abstract: A pedal bracket assembly translates pedal motion into a first switching motion without change of position being sensed by a position sensor. Additional pedal motion does not further change the switch position, but is translated into motion sensed by the position sensor. In this way, the switching function and position transducer functions are maintained independent one from the other, while allowing the two functions to be combined into a single sensor assembly.

Abstract: A method of testing for the presence of dibromonitrilopropionamide in a sample, which comprises adding to the sample, under alkaline conditions and in the presence of magnesium ions, a phenolic or anilinic compound that generates a colour; and observing the resultant colour. The appropriate reagents may be formulated as a kit, e.g. using pyrocatechol as the phenolic compound.
Abstract: An aqueous sample containing methylenebisthiocyanate or another compound capable of releasing an aldehyde is assayed by determining the amount of aldehyde released by conversion with respect to a sample from which existing aldehydes have been separated. An aqueous sample containing glutaraldehyde or another aldehyde which having at least 2 C atoms is assayed by adding an agent which gives a water-insoluble complex, and determining the amount of complex or, after regeneration, the aldehyde.

Abstract: A low TCR cermet composition of pre-alloyed nickel-chromium may be blended with pre-alloyed titanium silicide to form an extended range low TCR cermet composition. Additionally, the nickel-chromium cermet composition may also be blended with a titanium silicide composition to form a blending pair that allows for unlimited resistivity control over a decade of resistance. Other low TCR base metal alloys in addition to nickel-chromium are further contemplated.
Abstract: A multilayer circuit card is disclosed that interconnects multichip modules to each other electrically, and simultaneously acts to dissipate otherwise destructive thermal energy. The circuit card is comprised by an aluminum nitride core and two opposed low temperature co-fired ceramic laminates, all three laminated to each other.
Abstract: A Kapton element is terminated by bringing an element which is wrapped at a substantially fixed radius from a rotor out through a linear portion to the terminations. This causes the terminations to be at an angle to the line between the electrical connector and the rotor. A standard termination is then made without the need to bend a sharp turn in the Kapton element--an advantage that is more significant as the bend radius is increased for tighter package sizing. This concept also offers improved assembly, reducing the effort to automate production.
Abstract: A high power, hermetic, low cost, high reliability package for electrical devices is described. The package includes in the preferred embodiment an aluminum nitride substrate, copper thick film ink screen printed and fired upon the substrate, a Kovar ring brazed to the copper thick film ink, a thermally dissipating device mounted, the device bonded to electrical feed-throughs that pass through the Kovar ring, and a cover bonded to said Kovar ring to form an additional part of the hermetic seal.
Abstract: The apparatus comprises a boiler (2) provided with an electric resistance heating element (3) arranged to heat and vaporize water, a water reservoir (6) independent of the boiler and a pump (8) designed to transfer water from the reservoir to the boiler. In the boiler a predetermined amount of water substantially corresponding to 50% of the overall capacity of the boiler itself is kept constant, thereby maintaining the steam amount unaltered and making the steam use always immediate. A steam control valve connected to the boiler (2) is driven by a magnetic float switch (14) housed in the water reservoir (6) to stop the steam emission when the cold water reservoir (6) is empty.
Abstract: Conductive material is applied to a resistor to provide controlled shunting of current from localized regions of the resistor that would otherwise destructively fail during surge. Various embodiments are disclosed having varying resistance, dimension and placement. The continuity of the original resistor material is not altered, nor is the current diverted in such as way as to create a new localized regions that might destructively fail. The resistors so designed have application in lightning surge environments, power supply and power input circuitry and other applications where potential short duration surges might otherwise cause destructive failure of standard resistors.
Abstract: A method for assaying Bronopol or Permachem, i.e. 2-bromo-2-nitro-1,3-propanediol or 2,2-dibromo-2-nitroethanol, or a derivative thereof in a sample, comprises adding to the sample a diazo compound which reacts with the compound under test to form a colored species, and determining the presence and, if desired, concentration of the species colorimetrically.
Abstract: The resistor network of the present invention uses nodal common points with branch conductors for distribution of electrical power to a plurality of resistors. Separating the branch conductors are electromagnetic shields which isolate individual resistors and branch conductors so as to reduce crosstalk between resistors. Additionally, resistors are alternately patterned upon each side of a substrate in order to further reduce crosstalk.
