  • Patent number: 9874195
    Abstract: A pressure-measuring glow plug device includes a module housing, a glow plug configured to ignite a combustion mixture in a combustion chamber of an internal combustion engine, and a pressure-measuring device. The pressure-measuring device has a pressure sensor configured to detect the pressure in the combustion chamber. The glow plug is connected to the module housing by a flexurally elastic membrane. The force acting on the glow plug in the combustion chamber is transferred to the pressure sensor, which is supported on a supporting element by a preloading force. The supporting element is fastened rigidly to the module housing by a sensor housing. The glow plug device further includes a separate loading sleeve that is connected at one end to the pressure-transferring piece and at the other end to the supporting element. The loading sleeve is configured to apply the preloading force for the pressure sensor.

  • Patent number: 9541291
    Abstract: A pressure measuring glow plug includes: a housing in which a heating pin for igniting a combustion mixture of an internal combustion engine and a pressure measuring unit for recording a combustion chamber pressure of the internal combustion engine are situated. The heating pin has a glow current contact for an electric heating element. At the end of the heating pin facing away from the combustion chamber, a pressure transmitting element is fastened, which transmits the combustion chamber pressure acting on the heating pin to the pressure measuring unit. The pressure transmitting element is sleeve-shaped and forms an accommodation space for the glow current contact of the heating element.

  • Patent number: 9500365
    Abstract: A pressure-measuring device for recording a pressure in a combustion chamber of an internal combustion engine, having a force transmission body, situated in a housing, which is exposed to the combustion chamber and which transmits the combustion chamber pressure to a pressure-measuring unit at least indirectly by an axial motion, and having a flexible diaphragm, which is situated between the force transmission body and the housing. The flexible diaphragm is configured to be resilient to implement the axial motion of the force transmission body within the housing. A flexible additional diaphragm is connected ahead of the flexible diaphragm on the combustion chamber side, which seals the flexible diaphragm from the combustion chamber.

  • Publication number: 20150135811
    Abstract: Described is an elastic diaphragm for a pressure-measuring device for ascertaining a pressure in a combustion chamber of an internal combustion engine, especially a self-ignitable internal combustion engine, the diaphragm being accommodated in a housing of the pressure-measuring device in order to separate a pressure chamber from a cavity and in order to seal the housing from the pressure to be measured. The diaphragm has a pressure-application region. Furthermore, the diaphragm is developed in the shape of a ring and in cross-section has a U-shape that is open toward the cavity; the region of the diaphragm on which the pressure is acting is geometrically made up of two interconnected quarter circles, so that the pressurized region has a structure that is self-supporting with respect to the arising combustion pressure loads.

  • Patent number: 7833959
    Abstract: The present invention relates to a method to decrease the flammability of normally flammable alcohols and solvents. The additive is Alpha Terpineol, which will increase the flash point of flammable alcohols or solvents, by blending the Terpineol into the flammable solvent or alcohol. Solvents such as acetone, methanol, ethylacetate, ethanol and xylene, to name a few, increases flash points by 50° C. to 60° C., by addition of 12-14% terpineol. The said solvent can then be blended with other organic solvents to produce performance solvents, such as paint strippers with flash points greater than 140° F. and meet Federal and state Volatile Organic Compound regulations.

  • Publication number: 20100247784
    Abstract: A method for applying a coating meeting a predetermined volatile organic compound (VOC) standard. The compound functions as a coating and plasticizer. The inventive method involves mixing acetone and terpene alcohol, or terpineol, to form a solvent system with a flash point of at least 140° F. A resin is solubilized into the solvent system and forms a coating. The coating is cast over substrate surfaces to cure and dry. The solvent system produced by the inventive method can also be used in other applications including as a cleaning composition.

  • Patent number: 4016408
    Abstract: A method and apparatus for monitoring and controlling a plurality of power supplies in a computer or similar complex electronic apparatus provides the steps of normalizing each power supply output according to a common nominal val ue, comparing the normalized values to a reference having values according to the normalized upper and lower limits specified for each power supply, and conducting a quantative measurement of out-of-tolerance test values. The specific upper and lower tolerance values for each normalized output are stored in digital form and the measurement of an out-of-tolerance reading is by comparison to a digital ramp extending only from the specific maximum or minimum tolerance threshold which is exceeded. The testing of plural power supplies having the same upper or lower normalized tolerance can be conducted as a group of tests against the same reference.
