Title: Ensembles poincon a longueur reglable
Inventor: SHULDES GLEN M
IPC: B21D28/34
Filed: 2002-04-12
Granted: 2009-09-15
Abstract: L'invention concerne des ensembles poinçon à longueur réglable. L'ensemble poinçon décrit peut être utilisé avec une presse poinçonneuse comprenant un porte-outil (108) conçu pour recevoir l'ensemble poinçon, et un vérin (120) conçu pour se déplacer selon un mouvement longitudinal le long d'un axe de vérin. Le présent ensemble poinçon réglable en longueur comprend de préférence une unité (124) poinçon connectée par vissage avec une unité (126) d'entraînement présentant une surface sur laquelle le vérin de la presse poinçonneuse vient frapper. La longueur de l'ensemble (102) poinçon peut être réglée par la rotation d'une des unités relativement à l'autre unité. Cet ensemble poinçon à longueur réglable comprend de préférence un mécanisme (150) de verrouillage permettant d'empêcher sélectivement la rotation de l'unité poinçon par rapport à l'unité d'entraînement. Le mécanisme de verrouillage comprend de préférence un axe (134) de verrouillage monté sur une des unités et une clavette (148) de verrouillage connectée de manière coulissante avec l'autre unité de manière que la clavette de verrouillage coulisse le long d'un chemin (152) de clavette de verrouillage. Le chemin (152) de la clavette de verrouillage est disposé de préférence de manière à former un angle avec l'axe (122) du vérin lorsque l'ensemble poinçon est monté dans le porte-outil.

Title: Right angle safety needle
Inventor: SANDSTROM JEFFREY D
IPC: A61M5/158
Filed: 2002-09-30
Granted: 2010-08-03
Abstract: A right angle safety needle (32) has a base (4) to which an arm (34) is hingedly mounted at a proximal portion. The base (4) has an opening (18) at its distal portion wherethrough the vertical portion of the right angle needle (32) extends. A well (20) is formed adjacent the opening (18) and a dam (22) is provided on the side of the well (20) away from the opening (18). To retract the needle (32) from the opening (18), the horizontal portion (26) of the needle (32), which may be encased in an arm (34), is rotated about the upright (56) to which it is hingedly connected so that the needle (32) is pivoted upwards and withdrawn from the opening (18). Once the tip of the needle (32) clears the opening (18), due to the tip of the needle (32) being offset from the body of the needle (32) and the fact that the needle (32) tends to flex forward, the tip of the needle (32) is entrapped in the well (20) adjacent to the opening (18). The dam (22) forward of the well (20) provides a backstop for any further forward movement of the tip of the needle (32), thereby fixedly retaining the needle (32) within the well (20). Stops (68) are provided in the device, at its arm (34) and base (4), to prevent the needle (32) from being further moved relative to the base (4) once the tip of the needle (32) is entrapped in the well (20) of the base (4).

Title: Means for optimizing unit injectors for improved emissions/fuel-economy
Inventor: JONES JERRY A
IPC: F02M45/00
Filed: 2004-04-26
Granted: 2011-07-12
Abstract: A novel injection-pump plunger used in a unit injector for an EMD-type diesel engine has its upper (cut-off) control edge shaped to retard start of injection at full power from what it is with standard plungers, and to provide in a straight-line manner a relatively small increase in retardation from full load to idle. In a preferred form, the plunger has one or more steps in its upper (cut-off) control edge, the step or steps being formed between adjacent segments of the edge that are associated with different load points. A method of improving emissions/fuel-economy of EMD diesel engines comprises using prototype injection-pump plungers shaped within certain parameters, assessing their performance, selecting new patterns of timing based on the assessment, making new prototype plungers and assessing them, and repeating the steps of selecting, making and assessing if and as required until an assessment indicates compliance with applicable performance standards.

Title: Ground levelling apparatus
Inventor: SIELING NICOLAAS LAURISSE
IPC: E02F3/76
Filed: 2003-03-21
Granted: 2012-05-22
Abstract: Tractor towed ground levelling apparatus includes an elongate cutting edge mounted on a cylindrical steel beam. The beam carries road wheels and is connected to a foldable drawbar hitched to the plough arms of the tractor. Alternatively, the drawbar may be connected to the drawbar of the tractor through a height adjusting mechanism. When folded the drawbar is nestled against the beam and can be hitched to a road vehicle. The road wheels lift when the drawbar is unfolded, lowering the beam to the ground. The beam has a skid bar that skids over the ground in use. The cutting edge is mounted close to the skid bar and positioned so that its ground engaging edge is level with and parallel to the skid bar. The cutting edge is lifted or lowered by the plough arms or the height adjusting mechanism.

Granted: 2011-07-19
Abstract: L'invention concerne un procédé se rapportant à un assemblage au moyen duquel de l'énergie peut être extraite d'un fluide en écoulement. On propose de considérer tous les dispositifs de l'assemblage en tant que corps unique d'écoulement. En particulier, les dispositifs en amont de l'assemblage sont réglés de façon qu'ils exercent des forces latérales (horizontales et/ou verticales) sur l'écoulement de fluide avec pour résultat qu'il se produit des écoulements qui guident le fluide rapide vers les dispositifs d'extraction d'énergie et guident le fluide lent en dehors de ces dispositifs (dans certains cas, l'inverse étant aussi avantageux). Cet assemblage comprend, en particulier, une ferme éolienne et les dispositifs qui produisent les forces latérales sont constitués d'un type de générateur de vortex pour la couche limite atmosphérique, et sont constitués, plus particulièrement de turbines éoliennes horizontales ou verticales positionnées selon un angle par rapport au vent. Un réglage systématique des dispositifs selon certains schémas permet d'augmenter la production en raison du fait que premièrement, une partie de l'air lent dans la partie inférieure de la couche limite atmosphérique est déjà écartée avant que le vent atteigne la ferme et deuxièmement, que l'air lent de sillage sortant des dispositifs d'extraction d'énergie est écarté par les circulations et remplacé par de l'air rapide provenant d'une plus grande hauteur. Un certain nombre d'avantages se dégagent de cette invention. Par exemple, la vitesse du fluide à l'emplacement des dispositifs extracteurs d'énergie est plus élevée dans de nombreux cas ce qui mène à une production plus importante. En outre, les dispositifs extracteurs d'énergie se trouvent dans une certaine mesure moins dans les sillages et peuvent donc être placés plus proches les uns des autres, ce qui économise du câble et augmente la puissance installée par unité de surface.

Title: Multiple pass location processor
Inventor: ANDERSON ROBERT J
IPC: H04W4/90
Filed: 2004-03-31
Granted: 2012-12-18
Abstract: A multiple pass location processing method, for use in a wireless location system (WLS), comprises identifying a received transmission as requiring multiple pass location processing whereby the WLS produces a first, lower quality location estimate and then subsequently produces a second, higher quality location estimate. The WLS then produces the first location estimate and provides it to a first location application, and then produces the second location estimate. The second location estimate may be a more accurate estimate than the first location estimate and/or of a higher confidence than the first location estimate. This method is suitable, but not limited, for use in connection with locating a wireless transmitter involved in an emergency services call and routing the call to a call center.

Abstract: Techniques for performing erasure detection and power control for a transmission without error detection coding are described. For erasure detection, a transmitter transmits codewords via a wireless channel. A  receiver computes a metric for each received codeword, compares the computed metric against an erasure threshold, and declares the received codeword to be "erased" or "non-erased". The receiver dynamically adjusts the transmit power based on whether the codewords met the erasure threshold or not.
