Abstract: Steerable tag axle assemblies include an axle mounting lever carrying a wheel on a stub axle and either a kingpin pivot or a spherical bearing pivot for laterally turning the wheel.  The lever pivots between a stowed position and a deployed position where lateral forces from the ground urge the wheel to follow the vehicle.  In one embodiment, a kingpin pivot connects the stub axle to the lever and a tie rod maintains alignment of the pair of stub axles.  In another embodiment, a kingpin pivot connects the lever to a pivoting shaft attached to the vehicle.  The shaft turns as  the  lever  moves  between  the  deployed  and  stowed positions, and the lever pivots laterally at the kingpin pivot  to turn the wheels.    In  another  embodiment,  a spherical bearing is carried by a spherical bearing mount securely attached to the vehicle.  The bearing engages the lever in a bearing cavity,  such that the lever pivots laterally and between the stowed and deployed positions on the bearing.  Lateral movement of the wheel is limited in each embodiment.

Granted: 1999-11-30
Abstract: A method for refining lignocellulose-containing material into pulp in a primary refiner, preferably a disc refiner (32). The material is preheated (20, 22, 24) to a temperature greater than the glass transition temperature of the lignin in the material. The material is held at this temperature for a time interval under one minute, preferably in the range of 10-30 seconds. The heated material is then subject to high intensity refining in the refiner to produce pulp. The resulting pulp has a high quality which affords great flexibility in secondary refining (44). The preheat retention interval can be adjusted to emphasize different objectives, such as reducing total specific energy (Fig. 2) or increasing strength properties (Figs. 3 and 4).

Abstract: An improved furnace including a two-speed inducer motor which can be used as a single speed motor for either a vertically or horizontally vented furnaces. The inducer has a common terminal, a low speed terminal and a high speed terminal. One lead is attached to the common terminal and, depending on whether the furnace is vented horizontally or vertically, either the high speed or low speed terminal is used. If the furnace is vented vertically, one lead is connected to the common terminal and the other lead is connected to the low speed terminal. Thus the furnace operates at a low speed when the furnace is vented vertically. If the furnace isvented horizontally, one lead is connected to the common terminal and the other lead is connected to the high speed terminal. Thus, the inducer motor operates at thehigher speed when the furnace is vented horizontally.

Title: Isolation and amplification of nucleic acid materials
Inventor: BOOM WILLEM RENE
IPC: C12Q1/6806
Filed: 1997-02-14
Granted: 2008-12-23
Abstract: The invention relates to methods for easily separating single stranded nucle ic acid material from double stranded nucleic acid material in a sample containing both. By the right choice of at least one chaotropic agent, preferably a guanidine salt, at a selected concentration and other suitable conditions such as chelating agents, pH and the like, it is possible to bind double stranded material to a solid phase such as silica particles, whereas single stranded material will not bind under those circumstances. By separating the silica particles from the sample the double stranded nucleic acid material is removed. It can easily be elute d from the silica particles. In a second step the single stranded material may be bound to a solid phase by selecting a different set of conditions. The particles can again be separated from the sample and the single stranded material may now be eluted. For every efficient separations, the process may be repeated. Following the separation of the two kinds of nucleic acid, either kind may be amplified. Methods of amplification are provided which do not need sequence data of the material to be amplified. In these methods a primer will be provided with an amplification motif and a random hybridization motif.

Granted: 2002-08-13
Abstract: A method of minimizing power consumption within an electronic price label (EPL) which conserves battery life.  A time period for removing power from a transceiver within the EPL is determined by a computer from price change frequency data.  A message to control circuitry within the EPL is sent by the computer as soon as possible following a change in price displayed by the EPL.  The message includes a command to remove power from the transceiver and the power down time period.  Power is removed from the transceiver by the control circuitry.  The control circuitry counts until the power down time period is exhausted.  Power is applied to the transceiver by the control circuitry when the power down time period is exhausted.  Finally, a first time within the control circuitry is synchronized by the control circuitry to a second time indicated by the computer after the power down timer period is exhausted and before any additional message is sent to the EPL.
