Title: Oxidative halogenation and optional dehydrogenation of c3+ hydrocarbons
Inventor: HICKMAN DANIEL A
IPC: B01J27/06
Filed: 2002-04-23
Granted: 2009-11-17
Abstract: An oxidative halogenation and optional dehydrogenation process involving contacting a reactant hydrocarbon having three or more carbon atoms, such as propane or propene, or a halogenated derivative thereof, with a source of halogen, and optionally, a source of oxygen in the presence of a rare earth halide or rare earth oxyhalide catalyst, so as to form a halogenated hydrocarbon product, such as allyl chloride, having three or more carbon atoms and having a greater number of halogen substituents as compared with the reactant hydrocarbon, and optionally, an olefinic co-product, such as propene.  The less desired of the two products, that is, the halogenated hydrocarbon or the olefin as the case may be, can be recycled to the process to maximize the production of the desired product.

Abstract: A method and apparatus for short circuit welding includes providing welding power suitable for short circuit welding, sensing the stick out length, and adjusting the welding speed, such as wire feed speed or travel spead, adjusting a welding parameter, or adjusting the gas mixture in response thereto. Stick out is preferably determined by measuring a welding parameter, and performing an FFT on the parameter, and then calculating stick out, in one embodiment. Stick out can be either CTTWD or CPTPD. The system can determine when a short is about to clear by calculating a value V c defined by V c = d/dt(kl*dp/dt), and comparing V c to a V threshold, which varies in response to welding cycle history.

Title: Compact vibration cancellation device
Inventor: LEDBETTER TIMOTHY K
IPC: B64C27/00
Filed: 2002-08-26
Granted: 2008-10-28
Abstract: The present invention relates to an improved vibration cancellation device (10) designed to overcome many of the shortcomings inherent in prior devices.  In many embodiments, the vibration cancellation device (10) is smaller in scale than prior designs, facilitating more versatility with respect to design options. The device of the present invention achieves a smaller size partly due to the use of suspension springs (32) having an offset, rather than a parallel arrangement.

Abstract: The invention relates to a method and to a device for producing a rolled metal strip from a molten metal by producing a cast metal strip in a strip casting device (5) and then rolling the undivided metal strip in roll stand (18) to the final thickness of the strip. For controlling the course of the strip, strip guiding devices (19) are provided, especially upstream of the roll stand. In order to guarantee, with little components required, a stable insertion of the metal strip into the roll stand at the input side of the roll stand or at the site of the rolling in accordance with the strip dimensions, the strip guidance interferes or is carried out at a distance of 1.0 to 10.0 times the strip width, preferably at a distance of 1.5 to 5.0 times the strip width, upstream of the roll stand.

Abstract: A battery powered fishing line bite detector alarm (20) producing visible and/or audible alarm signals is disclosed.      An arm (96), installed within the alarm, integrally connects to a modified leaf on-off switch (66). The alarm attaches to a fishing rod (33) in front of a fishing reel (35) mounted on the rod. Fishing line (38) is threaded into the arm and adjusted such that slack is provided between the rear of the alarm and the front of the reel thereby allowing forward arm movement. The fishing line is further inserted until desired resistance of forward and backward line movement within the arm is achieved. Applied tension to the line forces the arm to actuate. A tension spring clip (84) connected to a switch lever (78), and a common leaf contact arm (76), pulls contact arm closer to an upper common contact point (74) until contact is made activating the alarm signals. Increased tensioning pulls the line through a variable sized slit (110) and into a line hole (100B), releasing tension on the arm and causing the contact arm and contact point to break contact, while allowing the arm to return to a self-adjusting alarm ceasing position.

Abstract: Screen (10) for a user interface of a television schedule system and process consists of an array (24) of irregular cells (26), which vary in length, corresponding to different television program lengths of one half hour to one-and-one half hours or more. Because of the widely varying length of the cells (26), if a conventional cursor used to select a cell location were to simply step from one cell to another, the result would be abrupt changes in the screen (10). By restricting cursor movements to the regular cells, abrupt screen changes will be avoided. A conventional offset shadow (34) which is a black bar underlines the entire cell and wraps around the right edge of the cell. To tag the underlying position which defines where the cursor (32) is and thus, where it will move next portions (36) of the black bar outside the current underlying position are segmented, while the current position is painted solid.
