Abstract: A method and apparatus for the construction of a two-layer flooring system for use at a construction site such as an oil well drilling site. The flooring system is particularly well suited for use in areas with dry, sandy soil. The flooring system is formed by interlocking both the ends and sides of a plurality of mat units (10). Each of the mat units (10) includes two layers of boards (12, 14). The first layer (12) has end locking tabs (22) extending beyond the edge (18) of the first layer and corresponding end locking slots (24), formed by offsetting selected boards (16). The second layer (14) similarly includes side locking tabs (32) and corresponding side locking slots (34), also formed by offsetting selected boards (39, 38). The arrangements of these tabs and slots is such that half-size units (58) and inverted units (60) may be utilized, allowing a wide variety of patterns of interlocking units to be utilized for the flooring system. The method of constructing a flooring system utilizing such units includes positioning one mat unit (10) adjacent to other mat units and inserting the tabs (22) into the corresponding slots (24) to interlock the units. By interlocking a plurality of such units, a two-layer flooring system is fabricated at a construction site which is strong and sturdy enough to support heavy equipment, yet easily installed and removed.

Granted: 2001-11-27
Abstract: A facsimile signal transmission system which satisfies the stipulation of the signal sending time and the stipulation of the signal time interval for enabling successful facsimile communication even if a detection delay or a sending delay occurs.      In a facsimile signal transmission system for transmitting a digital command signal (DCS signal), an echo protect tone signal (EPT signal), a training signal, and a training check signal, if an IDLE message signal output from a transmission part at the end of the DCS signal is received in a reception party, a first timer operated for a first predetermined time is started. When the first predetermined time has elapsed, sending of the EPT signal to the reception facsimile terminal is started. A second timer operated for a second predetermined time is started at the same time as sending of the EPT signal is started. When the second predetermined time has elapsed, sending of the EPT signal is terminated. A third timer operated for a third predetermined time is started at the same time as sending of the EPT signal is terminated. When the third predetermined time has elapsed, sending of the training signal to the reception facsimile terminal is started.

Abstract: Various polysaccharides are prepared by reacting glucose or glucose-containing materials such as hydrolyzed starch with a polyol such as sorbitol in the presence of mineral acids such as phosphoric, hydrochloric and/or sulfuric acid. In one embodiment, polydextrose is prepared by reacting glucose or glucose-containing materials such as hydrolyzed starch with a polyol such as sorbitol in the presence of low levels, i.e., from about 0.001 % to about 0.09 %, more narrowly from about 0.01 % to about 0.06 %, phosphoric acid. In other embodiments, other mineral acids or mixtures thereof may be employed. In alternate embodiments, a combination of mineral and organic carboxylic acids such as citric acid are employed. Because of the low levels of catalyst used in certain preferred embodiments, minimal or no off-flavors and little color are formed during the course of the reaction.

Abstract: Procédé et système permettant d'appliquer le contrôle d'accès aux fichiers à des dispositifs clients à l'aide de modèles de contrôle d'accès et de protocoles de serveur de fichiers multiples et divers. Un serveur de fichiers à protocoles multiples identifie chaque fichier à l'aide d'un modèle de contrôle d'accès particulier tiré d'une pluralité de modèles possibles et applique ce modèle particulier à tous les accès à ce fichier. Lorsque le serveur de fichiers reçoit une demande pour ce fichier utilisant un modèle de contrôle d'accès différent, le serveur de fichiers traduit les limites de contrôle d'accès pour ce fichier en limites non-moins-restrictives dans le modèle différent. Le serveur de fichiers restreint l'accès par le dispositif client à l'aide des limites de contrôle d'accès traduites. A chaque fichier est attribué le modèle de contrôle d'accès de l'utilisateur qui a créé le fichier ou qui a été le dernier à poser les limites de contrôle d'accès pour ledit fichier. Lorsqu'un utilisateur ayant un modèle de contrôle d'accès différent pose des limites de contrôle d'accès, le modèle de contrôle d'accès pour ce fichier est remplacé par le nouveau modèle. Les fichiers sont organisés en une hiérarchie sous forme d'arbre, chaque arbre étant limité à un ou plusieurs modèles de contrôle d'accès (ce qui peut limiter la capacité des utilisateurs à poser des limites de contrôle d'accès pour des fichiers dans cet arbre). Chaque arbre peut être limité à un format modèle-NT-seulement, à un format modèle-Unix-seulement ou à un format mixte de modèles NT ou Unix.

Granted: 2007-11-13
Abstract: The present invention discloses a process to manufacture toothed blades such as saw blades. The blades are made from strip stock that has spaced notches along at least one edge defining tooth blanks therebetween. The notches may be any convenient shape and made at any angle such as 45° to the edge. That angle becomes the rake or front incline angle of the tooth. The teeth are then formed by pinching the metal of the tooth blank at a particular location near the notch so as to displace the leading or rake edge of the notch below the original edge.  The pinching is done either in a batch process of blade by blade on punch and anvil, or in a continuous process between pinching rollers having peripheral punches rotating in timed sequence with the notched strip passing therebetween. A  single step punch and dimple method is also disclosed.

Title: Method and apparatus for device-dependent calibration of relays for high accuracy operation at zero-crossing of input power signal
Inventor: BALDWIN JOHN R
IPC: H01H45/00
Filed: 2001-08-27
Granted: 2012-01-03
Abstract: A system and method are provided for ensuring increased accuracy of individual relays (e.g., within a control system comprising a sensor) to close substantially coincidentally with respect to a current zero-crossing of an incoming power supply waveform. To determine timing of contact operation, a microcontroller operates the contacts in response to one of a series of test pulses, and determines the amount of time required for contact operation. The difference between timing of contact operation and zero-crossing is determined and adjusted to offset errors incurred by microcontroller threshold variations and power supply voltage variations. The calibrated value is then provided to the sensor in order to extend sensor life.
