Abstract: An implement depth control system includes a rotating link pivotally connected to the frame adjacent the depth control cylinder.  A cylinder pin contacts and rotates the link when the implement is lowered toward the field operating position.  One end of an adjustable length member is threaded through a turnbuckle mounted on the link and contacts an actuator to limit cylinder retraction and set operating depth. The opposite end of the member extends to an easily accessed location on the implement and includes a crank handle for turning the member and thereby adjusting the length between the turnbuckle and actuator to vary the depth setting.  An indicator near the crank handle provides an accurate depth indication at any depth setting, and relative depth adjustments may be made quickly while the implement is in the lowered field working position.

Title: Method of bovine herd management
Inventor: EVERETT ROBERT W
IPC: A01K67/02
Filed: 1994-02-15
Granted: 1998-07-14
Abstract: The present invention features a method of bovine herd management based upon a d ynamic mathematical model. The method gathers data on milk production on a periodic or routine basis for each cow in the herd. The data includes factors denoting both the quantity and the quality of the milk being produced. A database for each cow is establish ed and continuously updated. A mathematical herd management model is used to establish the database, wherein the gathered data i s then modified and used to interpret and determine the actual productivity of each cow in the herd for that test day. Using this data, a manager of the herd can then breed those cows having a capability superior to their associates the herd. Likewise, the less productiv e members of the herd can be culled or eliminated from the herd. Another aspect of the invention includes the use of the database to qu antitatively assess the effect of change, including changes made in formulas, in environmental conditions and in breeding practices. Thus, f or the first time, herd management can be scientifically controlled on a quantitative basis. Genetic evaluations can be made from the dat abases of many herds in order to select primary, artificially inseminated, bulls capable of siring daughters in many herds. For maximum effic iency, databases of many herds combined or linked across the entire nation.

Abstract: A prebaked carbon-based anode of an electrolytic cell for the production of aluminium, in particular by the electrolysis of alumina in a molten fluoride electrolyte, is treated over its sides and top to improve the resistance thereof to erosion during operation of the cell by oxidising gases released at the anode, by immersing the anode in a boron-containing solution containing 5-60 weight % of H3BO3 or B2O3 in methanol, ethylene glycol glycerin or water with a surface-active agent, e.g. at 80.degree. to 120 .degree.C. After 2-60 minutes immersion, the boron-containing solution is impregnated to a depth of 1-10 cm, usually about 2-4 cm over the top and side surfaces of the anode to be protected, producing a concentration of boron in the impregnated surface from 200 ppm to 0.35 %.

Title: Variable transmission bit rate discrimination method and apparatus
Inventor: TAKAKI TETSUYA
IPC: H04B1/69

Granted: 1999-12-28
Abstract: The invention provides a variable bit rate discrimination method and apparatus wherein a transmission bit rate of data received by a mobile station in a mobile communication which employs a spectrum spreading method can be discriminated readily to realize reduction in time required for decoding processing and miniaturization in circuit scale.  A variable bit rate including four different transmission bit rates is used as a transmission rate of a traffic channel from a base station to a mobile station, and transmission data are encoded using convolutional encoder for error correction and transmitted.          In the mobile station, received data are decoded for the four individual transmission bit rates using Viterbi decoders, and the decoded received data are compared with coded data sequences generated from the convolution codes to obtain path metric values which are sum totals of errors of the received data.  Then, one of the transmission bit rates which exhibits a lowest one of the path metric values is selected as a bit rate used for transmission of the transmission data.          Consequently, after Viterbi decoding, no further encoding is required.

Granted: 2000-04-11
Abstract: A system and method of calibrating pressure transducers in an electro-pneumatic brake system for a railroad train in which a locomotive microprocessor generates a respective best fit curve for the train brake pipe, supply reservoir and brake cylinder pressures that approximates the actual train pressure therefore.   These best fit curves are generated from the pressure transducer readings of these pressures at each car by employing an equation based on a fourth order polynomial.      Each car is then provided with a theoretical reference pressure  signal  from the best  fit curve  for each of  the mentioned brake pipe, supply reservoir and brake cylinder pressures, according to the position of the car in the train.          The theoretical reference signal is then compared at each car with the car pressure transducer reading for the respective brake pipe, supply reservoir and brake cylinder pressures to obtain  a  transducer  error  correction  factor  that  remains constant  through  a  full  range  of  pressures.    The  error correction factor can be further calculated on the basis of a linear equation to obtain a variable error correction factor.

Abstract: ABSTRACT OF THE DISCLOSURE     A dancer's shoe, slipper or the like having a stiff sole comprised of split front and rear soles separated at the arch.  To enable the dancer to stand on pointe, the front sole is "cup" shaped with a generally "C" shaped cross-section.  The upstanding wall of the front sole is attached to the sides and may extend up the front of the shoe box.  This enables the front sole to bend upward around an axis across the foot when the foot bends but prevents the front sole from bending downward around such an axis which enables the dancer to stand on pointe on the tip of the shoe.  The wall may be notched to facilitate bending at a particular location.  There may be a rear sole spaced from the front sole behind the arch.  To stiffen the shoe body, a toe box is provided in the front portion of the shoe upper.

Abstract: Base station generates a mobile station identifier which indicates a mobile station that a data signal is addressed thereto, and a head slot having a data signal when there is a data signal that has a length to be able to transmitted using one slot of a TDMA radio channel. When there is a data signal that has a length to be not able to transmitted using one slot, base station generates a head slot and continuous slots which contain at least a part of data signal. Base station transmits the head slot by using the starting slot which located at predetermined position every mobile station on the TDMA radio channel, and transmits the continuous slots by using slots which follow the starting slot. Mobile station receives the starting slot, and stops reception if the starting slot is not the head slot. If the starting slot is the head slot, the mobile station judges the mobile station identifier. Furthermore, if the mobile station identifier indicates other mobile station, the mobile station stops reception, on the other hand, if the mobile station identifier indicates itself, the mobile station receives the continuous slot.
