Title: Movable subframe for tractor-trailers
Inventor: PIERCE PHILLIPI RANDSOME
IPC: B62D53/06
Filed: 1996-05-14
Abstract: A movable subframe or slider (120) for a tractor trailer includes a pair of elongated spaced-apart parallel main members (121) and at least one generally K-shaped cross member structure (122) which extends between and is attached to the main members. Specifically, the K-shaped cross member structure includes a base member (160) which extends perpendicularly between and is attached to the main members, and further includes a pair of inclined members (161), each of which extends angularly between and is attached to a respective one of the main members and the base member. Each of the main members is adapted to be slidably mounted on a respective one of a pair of depending parallel rails of a trailer, and a retractable pin mechanism (124) enables selective positioning of the slider along the rails for variable load distribution of cargo contained in the trailer. A hanger (123) depends from each of the main members adjacent to the ends of the base member for supporting an axle/suspension system. Components of the axle/suspension system also are mounted directly on and adjacent to the inclined members. The K-shaped cross member structure enables the slider to be relatively lightweight yet have improved capability for withstanding the combined vertical and bending lateral and longitudinal loads that the slider is subjected to during operation of the tractor-trailer while being relatively inexpensive to manufacture.

Title: Latch-up recovery in quantized feedback dc restorer circuits
Inventor: SHAKIBA MOHAMMAD HOSSEIN
IPC: H04L25/06
Filed: 1998-04-03
Abstract: A method and apparatus for avoiding and or recovering from the latch-up condition in a quantized feedback DC restorer circuit for use in a digital data communication system receiver. An automatic gain control (AGC) circuit controls the level of the received data by comparing the AGC output with a quantized output signal from the DC restorer. A carrier detect circuit detects the presence of data transitions in the quantized output signal, and in the absence of such transitions continuously ramps up the gain of the AGC until such transitions are detected. The carrier detect circuit can be further used to disable, either entirely or partially, the positive feedback path of the DC restorer in the absence of transition in the quantized output signal. The present invention further provides an inherent muting function of the DC restorer output signal in the absence of valid data transitions.

Title: Electric radiation source and irradiation system with this radiation source
Inventor: MUECKE JENS
IPC: H01J65/04
Filed: 1997-09-08
Abstract: A radiation source (36), in particular a discharge lamp suitable for operating a dielectrically hindered pulsed discharge by means of a ballast (37), has of least one electrode (41a, 41b) separated by dielectric material (40a, 40b) from the inside of the discharge vessel. By appropriately designing at least one of the electrodes (39) and/or the dielectric material (40a, 40b), local field reinforcement areas are created, so that during the pulsed mode of operation one or more dielectrically hindered individual discharges are generated exclusively in these areas, maximum one individual discharge being generated in each area. These areas are obtained in particular by shortening the spacing in locally limited areas, for example by providing on one of the electrodes hemispherical projections (42a, 42b-44a, 44b) which extend towards the counter-electrode. This measure achieves a time-stable discharge structure with a high useful radiation effectiveness uniformly distributed throughout the discharge vessel (38).
