Title: Method of controlling electrode force of spot welding gun
Inventor: BUNDOU ISAO
IPC: B23K11/25
Filed: 1998-02-25
Abstract: In a spot welding gun which is made up of a gun main body (2) which is operated for equalization by a driving source (6), a stationary electrode tip (3) which is immovable relative to the gun main body (2), and a movable electrode tip (5) which is connected to a pressing source (4), both electrode tips (3, 5) are pressed to a workpiece (W) with an even force, to thereby perform a high quality spot welding. The driving source (6) is controlled such that the electrode force of the stationary electrode tip (3), by the driving source (6), to the workpiece (W) becomes substantially zero. In this manner, there occurs no difference in the electrode forces by both the electrode tips (3, 5) to the workpiece (W).

Title: Method for producing impulse voltage sequences to operate discharge lamps and circuit pertaining thereto
Inventor: HITZSCHKE LOTHAR
IPC: H05B41/30
Filed: 1998-07-16
Abstract: A method for producing pulsed-voltage sequences for the operation of discharge lamps (8) by means of a pulsed discharge which is impeded dielectrically provides for some of the required pulse peak values to be replaced by an offset DC voltage component (U DC(t)). This has, inter alia, the advantage that correspondingly less EMI is generated when the pulsed-voltage sequences (U p(t)) are produced. It is also provided for a portion of the electrical real power injected into the discharge predominantly throughout the duration of the voltage pulses to be injected on the basis of the offset DC voltage (U DC(t)). For this purpose, a circuit arrangement provides a series circuit comprising a pulse circuit (1) and a DC voltage circuit (2), in which case the pulse circuit (1) can be designed for a power level that is lower than that in the prior art.

Title: Load proportional brake cylinder pressure limiting system
Inventor: ENGLE THOMAS H
IPC: B60T8/18
Filed: 1999-05-31
Abstract: A continuously variable load responsive brake pressure control valve controls the amount of brake pipe pressure for a railway vehicle. The system also includes means for isolating the load sensing means from transient inputs caused by normal vehicle motion. A  spring loaded isolator coupled with a matched hydraulic cylinder isolate wheel truck deflections with respect to the car body, preventing erroneous inputs to the load sensor of the variable load braking system so as to provide more accurate brake cylinder pressure according to vehicle load weight. The variable load limiting valve is continuously operable between an empty vehicle condition and a fully loaded vehicle condition and assures a minimum braking pressure, while also helping prevent sticking of the brakes.
