Title: Down-hole mud actuated hammer
IPC: E21B4/14
Filed: 1990-01-22
Abstract: Improvements in down-hole mud actuated hammers are disclosed. According to its broadest aspect the invention is a down-hole mud actuated hammer for use in a drill string, which includes a housing with an upper end having means for connecting to the drill string. A throat is located within the housing which throat includes a main flow passage to allow high pressure drilling mud to pass therethrough. A piston is provided which is adapted to move axially within the housing means to thereby reciprocate between an up position and a down position. The piston is moved between the up and down position by a minor portion of the high pressure mud which portion passes from the main flow passage into at least one piston actuating chamber. This minor portion of mud is exhausted from the piston actuating chamber to a low pressure region out of the housing without being returned to the main flow passage.

Title: System of relational entities for object-oriented computer-aided geometric design.
Inventor: LETCHER JOHN S JR
IPC: G06T19/00
Filed: 1992-12-17
Abstract: Geometric objects including points, lines, curves, surfaces and solids are defined and constructed in a system which retains and utilizes relationships and dependencies between objects in a directed graph (digraph) data structure. The primary advantage is automatic updating of the model, preserving dependencies, when an underlying object is changed. Multiple types of parametric curves and surfaces and multiple levels of dependency are easily supported through a recursive program structure. Difficulties of surface-surface intersection and trimming are largely avoided by provision of novel entities which permit construction of accurate and durable joins between surface objects. An example model of a sailing yacht design illustrates six surface objects of several types with the defined dependency relationships. The hull (271) deck (272), cabin forward (273), cabin side (274), cabin aft (275) and cabin top (276) surfaces intersect at joins (278), (279) which are accurate and durable. The connectivity at the joins and the relative positioning of the surfaces are automatically preserved as the model is updated by changing one of the surfaces.

Title: Method and apparatus for cutting wet concrete.
Inventor: CHIUMINATTA EDWARD
IPC: B24B23/02
Filed: 1993-02-12
Abstract: A concrete cutting saw is provided for the cutting of grooves in the surface of wet concrete. The concrete saw generally comprises a motor driven rotating cutting blade mounted on a support structure. The concrete saw is supported during cutting by wheels, and has a skid plate with a slot through which the rotating cutting blade passes to cut the concrete. The cutting blade is mounted with a sound deadening blade housing and a number of shields and guards located about the skid plate. The skid plate is movably attached to the concrete saw and resiliently urged against the concrete during cutting so that it remains in contact with the surface of the concrete surrounding the cutting blade during cutting. The skid plate is constrained into a bowed configuration so that it is substantially flat during cutting. A variable speed transmission is drivingly connected to the wheels to propel the saw across the concrete during cutting. A sensor detects the relative position of the skid plate and the cutting blade to generate an electric signal which cooperates with the variable speed transmission to slow down the saw as it encounters hard aggregate, and to speed up the saw as it encounters soft concrete. A distance counter measures and displays the distance which the saw travels during cutting.

Abstract: La présente invention concerne un dispositif de commande servant à commander de manière appropriée le changement de vitesse de rotation d'un moteur, le faisant passer d'une vitesse désignée à une vitesse plus basse qui économise l'énergie quand le fonctionnement d'une machine hydraulique est arrêté, sans qu'un opérateur exécute aucune opération particulière de commutation. Quand tous les leviers de commande (14 à 21) sont mis dans une position neutre pour arrêter le fonctionnement, dans un cas où la vitesse de fonctionnement du levier actionné en dernier est plus basse, un délai est réglé plus long que quand la vitesse de fonctionnement est plus élevée. Quand les leviers de commande (14 à 21) sont maintenus dans la position neutre jusqu'à ce que le délai soit écoulé, on fait passer la vitesse de rotation du moteur à la vitesse inférieure du moteur. Si l'un quelconque des leviers de commande est actionné avant que le délai soit écoulé, la vitesse de rotation du moteur est commandée de manière à rester à la vitesse désignée.

Abstract: A system and method for making at least one cut in a catheter, guide wire or other elongate cylindrical object having a lengthwise axis, comprising a securing means for repeatedly releasing and then holding the elongate object in a position suitable for cutting it at an angle or transversely relative to its lengthwise axis, a manipulating means for moving the elongate object so that it can be disposed in the position suitable for cutting when it is released by the securing means, and a cutting means for forming the at least one precision cut in the elongate object to any desired depth. The securing means preferably comprises a rotatable collet clamp, and the manipulating means preferably comprises a pinch roller assembly for advancing and holding the elongate object. The cutting means is preferably a mechanical blade mounted on a rotatable spindle, and is free to move vertically and horizontally with respect to the elongate object to thereby control the location, size and depth of the cuts in the cylindrical object disposed adjacent thereto. The clamp is configured to hold and position the object to be cut so as to expose the entire circumference of the cylindrical object to the saw blade if desired. By releasing the clamp, the pinch roller advances the cylindrical object before the clamp is re-engaged to securely hold the cylindrical object for cutting.

Abstract: Cette invention concerne une station mobile (106) utilisée dans un système de communications à accès multiple par répartition de code (100) (AMRC). Cette station mobile (106) va effectuer un balayage des canaux pilotes sur une fréquence différente en réservant une trame périodique sur le canal avant, ceci de manière à ce qu'elle puisse changer de fréquences et effectuer des balayages sur d'autres canaux pilotes. Afin de conserver certains critères de qualité vocale, la station de base (102) et la station mobile (106) vont toutes deux coder les signaux vocaux selon un maximum d'un demi-débit, puis transmettre les informations sous forme de trafic secondaire avant la trame dans laquelle la station mobile (106) balaye l'autre fréquence. Afin de maximiser le compromis entre la qualité vocale et la fréquence de balayage, la station de base (102) va indiquer par messagerie à la station mobile (106) la période séparant les autres balayages de fréquence. Afin d'assurer la compatibilité, ce procédé peut faire l'objet de discussions en ayant recours aux techniques connues de négociation des configurations de services.
