Abstract: An orifice fitting with an orifice plate centered in the flow passage of an orifice fitting via direct contact between a cradle and the orifice plate. The orifice plate is centered via the use of an orifice plate carrier having two channels on its downstream side and two slots located in the bottom portion of the seat, which is located on the plate carrier's upstream side. The plate fits into the seat and a bottom portion of the plate's peripheral edge protrudes through the slots. A cradle having locating surfaces fits through the channels in the orifice plate carrier and firmly holds the orifice plate against the orifice plate carrier. The cradle can be positioned and then secured in place by two adjustable set screws and a stem piece of the cradle. Once the orifice plate has been centered via the positioning of the cradle, the stem piece of the cradle and the set screws can be welded into the body of the orifice fitting.  Alternatively, the cradle may be formed from weld metal added to the body of the orifice fitting and machined to define the cradle, or can be machined from a portion of the cast metal cradle. The method of the present invention involves the use of a cradle having locating surfaces to center an orifice plate in an orifice fitting by inserting the locating surfaces of the cradle in channels in an orifice plate carrier so that the locating surfaces contact and hold a bottom portion of the peripheral edge of the orifice plate and then positioning the cradle so as to center the plate.

Abstract: A game device for aiding in the learning of certain mathematical operations, such as multiplication tables, comprises a pad of score sheets for at least two players. Each score sheet includes a series of numbers ranging from 2 to 12 and, for each of the players, one or more blank spaces associated with each of these numbers. Four six-faced dice are provided and deployed to obtain four numeric readings ranging from 1 to 6 which are grouped in two pairs and added by one player within these two pairs for producing two sums which are multiplied by the same player to obtain a product that the player inserts in a blank space of the score sheet located opposite one of the two numbers corresponding to the aforementioned sums. The four dice are grouped in as many sets of pairs as possible so as to obtain, for a same deployment of the four dice, as many different products as possible for insertion in the score sheet. The players take turns in rolling the dice, determining the possible product(s) obtainable therefrom, and then placing these results on the score sheet always in the appropriate player's blank spaces associated with one of the multiplier and multiplicand until each of the blank spaces of one player is occupied by a product. Alternatively, the blank spaces can be of different background colors with the object of the game being filling out with numbers all of each player's same colored boxes before the other players. Various scoring systems are proposed for the colored boxes appropriated by each player.

Title: Determination du point de contact d'un embrayage
Inventor: LIU CHIA-HSIANG
IPC: G01M13/022
Filed: 1994-09-22
Granted: 1999-05-11
Abstract: La présente invention permet de déterminer automatiquement et de manière fiable le point de contact d'un embrayage contrôlé par une commande d'embrayage automatique. L'invention permet de déterminer le point de contact pendant que le moteur tourne au ralenti, que la transmission est au point mort et que le frein à inertie est appliqué. La commande d'embrayage engage l'embrayage de sorte que la vitesse initiale mesurée pour la transmission correspond à un signal de vitesse de référence de préférence entre 40 et 60 % de la vitesse au ralenti. Cela permet d'offrir de façon fiable le dégré d'engagement de l'embrayage à un couple peu élevé correspondant au couple de freinage. Lorsque la vitesse initiale pour la transmission se situe à l'intérieur d'une quantité prédéterminée du signal de la vitesse de référence, par exemple 4 %, l'invention permet de déterminer le point de contact de l'embrayage correspondant au degré d'engagement de l'embrayage. Le degré d'engagement de l'embrayage peut correspondre à un signal indiquant la position de l'embrayage ou un signal indiquant la pression de l'embrayage produit par un capteur sur place utilisé dans la commande automatique de l'embrayage. Si aucun signal de mesure de l'engagement de l'embrayage n'est disponible, le degré d'engagement de l'embrayage peut devenir le signal d'engagement de l'embrayage utilisé pour commander le degré d'engagement de l'embrayage. Le point de contact est établi en tant que différence entre ce degré d'engagement de l'embrayage pour un couple peu élevé, et un point de contact décalé de l'embrayage. La détermination peut commencer pendant que l'embrayage est totalement engagé et graduellement relâché selon la commande des vitesses d'entrée et de référence. Lorsque le point de contact est connu, l'embrayage est de préférence placé initialement juste au-dessus du point de contact connu et ensuite déclenché graduellement.

Abstract: The present invention provides a drilling system for drilling a borehole. The system contains a drill stem having a drill bit at its one end for drilling the borehole. A draw works containing a drum having a line spooled thereon and coupled to the drill stem controls the upward and down ward motions of the drill stem. A draw works motor is coupled to the draw works for rotating the drum in both the clockwise and counter clock wise directions. A rotary motor is coupled to the drill stem for providing rotational speed to the drill stem. A control circuit controls the operation of the draw works and the rotary motor. The control circuit receives information from various sensors which includes information about the rate of penetration, weight on bit, hook load, and rotational speed of the drill bit. During operation, the control circuit controls the rotation of the draw works to control the upward and downward motions of the drill stem. In one mode the control circuit maintains a. desired rate of penetration and if the weight on bit exceeds an upper limit, it reduces the rate of penetration by reducing the unwinding speed of the drum. In another mode of operation, the control circuit causes the drilling to start at an initial rate of penetration and then starts to vary the rate of penetration according to programmed instructions to optimize the drilling efficiency. In another mode of operation the control circuit causes the drilling to start at initial rotary speed and the weight on bit values and then varies the weight on bit and/or the rotary speed to obtain the combination of these parameters that yields the most efficient drilling of the borehole. If a mud motor is used to drill a borehole, the control circuit may be programmed to control drilling as a function of the differential pressure across the mud motor.

Abstract: A digital range correlator (50) for performing trian-gular ramp-weighted correlation relative to a reference word and providing an output data rate higher than the word rate.   Two correlator channels  (70,  80)  are provided. Channel 70 provides a ramp-weighted segment sum over a word segment, with N word segments per L-bit word, wherein each received bit of a received word segment is multiplied by a corresponding ramp weight, and the corresponding product is in turn multiplied by the corresponding delayed reference word bit.  The corresponding products over the word segment are accumulated to form a ramp-weighted word segment sum. Channel 80 provides a corresponding uniformly weighted word segment sum.   The respective ramp-weighted and uniformly weighted word segment sums formed over the two preceding word segments are stored in a shift register.  The ramp-weighted segment sums are scaled by +1 or -1 to represent the proper slope of the triangular weighting and accumulat-ed.   The uniformly-weighted segment sums are scaled by appropriate integers from 1 to N to represent the triangu-lar weighting, and accumulated with the accumulated ramp-weighted scaled segment sums, and with appropriate normal-ization  factors provide the correlator output signals. Digital Doppler or low pass filtering can be applied to improve the performance.

Abstract: A video surveillance system for monitoring an area is made up of a stationary pilot camera for monitoring the area and one or more moveable slave cameras for monitoring at least part of the area. Each slave camera is allocated to part of the area being monitored. The pilot camera produces a signal representative of the area. The location of a moving object in the area monitored by the pilot camera is determined. A signal is produced representing the location of the object. The slave cameras track the object based on the signal representing the location of the object. The pilot camera is provided with a fisheye lens and thus has a field of view wider than that of the slave cameras. The area being monitored is divided into cartesian, polar or spherical coordinates thereby enabling a microcomputer to instruct the slave camera to follow the object. The signal representative of the area is compressed and transmitted over a communications channel for remote monitoring.

Title: Prosthesis with articulating surface stress reducing contact edge
Inventor: PAPPAS MICHAEL J
IPC: A61F2/30
Filed: 1995-11-24
Granted: 2000-01-18
Abstract: A prothesis tibial bearing of thermoplastic material has a planar surface which engages the mating planar surface of a second prothesis component such as the tibial platform. The typically metal platform edge wipes across the inner surface region of the bearing causing deformation of the bearing   surface.      This   deformation   causes   stress magnification in the bearing at the platform edge region. The edge region of the platform planar surface is tapered to provide a gradual curved ramp between a relatively small corner radius at the platform edge and the platform planar surface,  the tapered region being tangential to the edge radius and to the platform planar surface.   The stress concentration increase at the edge region of the bearing is reduced at  the platform edge  region to below  100%  and preferably to about 25% of the stress value between the bearing and the platform in the region interior the platform edge.  The tapered surface region is preferably a curvature of tangential contiguous radii tangent to the platform planar surface, but may be planar.
