Abstract: An attenuated hinge spring assembly for a trunk lid of an automotive vehicle includes a coiled spring which is connected to a bracket secured to the vehicle, a threaded stud which is secured to the bracket, a plate which is slidably mounted on the bracket and the stud, a nut rotatably attached to said threaded stud and selectively secured to an arm, and a washer which lies between the plate and the nut.  The plate lies adjacent to the coiled spring.  The arm is pivotally connected to the trunk lid and to the bracket.  The spring is connected to the stud and the arm and uncoils as the arm pivots from a lowered position to a raised position to move the lid between a lowered position and a raised position.  When the lid is raised, the arm rotates which causes the nut to rotate and translate along the stud, which in turn causes the washer and plate to translate along said stud.  The plate moves against the coiled spring and frictionally brakes the spring and the nut to slow the momentum of the lid as the lid is being raised.

Abstract: A method for separation and quantitation of carbohydrate deficient transferrin (CDT) in order to decide a person's alcohol consumption during the most recent time. Lipoproteins are precipitated in blood serum, saturated with iron, and then the sample is centrifuged after a short storage period. The supernatant of the centrifuged mixture is then diluted with water. Subsequently the mixture is injected to an ion exchange column, when a saltgradient is used for separation of the isoforms of transferrin. A chromatogram is developed by means of HPLC and a filter for absorbance at 460 nm. Should the chromatographic profile show increased values of CDT (*,**), more than 0.8 % of total transferrin, it is a highly specific marker for heavy alcohol consumption.

Abstract: To largely, or entirely inhibit glow discharges during the start-up or run-on phase (Ta) of a high-pressure discharge lamp, the lamp is operated in a second time period (T2) immediately after ignition (T1) with continuous direct current during which the electrode of the lamp which then functions as an anode has reached emission temperature; in a third time period (T3), the polarity of the direct current is reversed and the other electrode, which now will function as an anode, is heated to emission temperature; thereafter, alternating current energy is supplied to both electrodes, typically in frequencies between 90 and 150 Hz. A suitable second time period (T2) can be about 2 to 2-1/2 second, the third time period (T3) being shorter. The total warm-up time may extend to a minute or more; current being supplied during the second, third and subsequent periods is usually higher, for example by a factor of 1.5 of the normal or rated operating current.

Abstract: A balanced pressure spool valve has a collector groove formed on the periphery of the valving spool adjacent the valving land, with an annular armature attached to the spool. The collector groove has a radially extending bleed hole which communicates with the axially extending pressure equalization bore in the spool. A solenoid coil upon increased current flow electromagnetically acts on the armature to progressively move the spool and the valving land closes outlet ports formed in the valving bore in which the spool is received. The collector groove intersects the outlet ports to provide bleed flow as-the ports-are closed by the valving land, thus attenuating the effect of any pressure force imbalance created by the increased flow velocity as the outlet ports are closed.
