Publication number: 20040228675Abstract: An adjustable clamping mechanism includes a slider block annularly disposed about a rod device within a mechanical press. The mechanism utilizes a press or interference fit connection between the components. During operation, high-pressure oil is injected into the location between the slider block and rod, thereby relieving the press fit and making it possible to have relative movement therebetween. An actuator causes selective linear displacement of the slider block along the longitudinal axis of the stationary rod during the release condition. Once the slider block is repositioned, the high-pressure oil is removed, which reactivates the press fit connection and causes the slider block to once again lock up against the rod and prevent movement therebetween.Type: ApplicationFiled: January 12, 2004Publication date: November 18, 2004Inventor: Richard J.

According to the present invention, the recesses may be grooves as a structural system with groove sections or depressions of microscopic size extending obliquely in relation to the central longitudinal axis of the ball-and-socket joint. Due to this novel design, a pumping effect is achieved during movements of the joint ball over the groove sections, and this pumping effect draws the lubricant present in the groove sections into the gap between the joint ball and the bearing shell, so that improved lubrication of the ball-and-socket joint compared with the state of the art is guaranteed under all operating conditions.Type: GrantFiled: April 11, 2001Date of Patent: March 9, 2004Assignee: ZF Lemförder Metallwaren AGInventors: Jürgen Gräber, Werner Stehr

Patent number: 6640853Abstract: The present invention relates to a wood-milling cutter. A circular cutter head includes a plurality of semicircular engaging grooves at the rim thereof for receiving a plurality of hilts with corresponding arched surface. A semicircular screw hole is formed in the middle of the top rim of the semicircular engaging grooves. A blade is received at the bottom of said hilt. A semicircular cavity corresponding to the semicircular screw hole of the cutter head is provided in the middle of the top of the hilt and equipped with an annular flange. Therefore, the semicircular screw hole and the semicircular cavity form a full circular hole to receive a trimming screw with an annular groove in the middle thereof. The annular flange of the semicircular cavity is engaged in the annular groove of the trimming screw while the threaded member of the trimming screw joins the semicircular screw hole of the semicircular engaging grooves.Type: GrantFiled: September 19, 2002Date of Patent: November 4, 2003Inventor: Hui-Ming Sun

Patent number: 6641323Abstract: A cylindrical body has a first part-spherical socket portion in the top, fittingly receiving a ball. A ball retainer has a second part-spherical socket portion facing the first part-spherical socket portion and receiving the ball therein. A post has a proximal end fixed to the ball and extends radially outward from the ball and away from the body to a distal end, and has screw threads at the distal end to receive a fastener thereon for attachment of an object to the distal end of the post. The ball-in-socket mounting of the post enables freely swiveling the ball and thereby the swiveling the distal end of the post to an infinite number of loci in a spherical envelope centered at the center of the ball, as well as enabling the post, and any object mounted to the post, to be rotated on a radial line from the center of the ball to the location of mounting of the object to the post. The body has a hydraulic cylinder in the bottom receiving a piston.Type: GrantFiled: January 22, 2002Date of Patent: November 4, 2003Inventor: Stephen E. Ronsheim

Patent number: 6632043Abstract: A connection coupling forms a line connection for liquid or gaseous substances to microcomponents (1) in platelet form. A coupling body (2), which is substantially U-shaped in cross section, accommodates the edge of the plate-like microcomponent (1) between an upper limb plate (3), which has the line connection (14), and a lower limb plate (5). An edge web (6) forms a transverse stop for an edge (8) of the microcomponent (1). A further stop means, for example a lug (9), forms a longitudinal stop for positioning of the microcomponents (1).Type: GrantFiled: June 21, 2001Date of Patent: October 14, 2003Assignee: Merck Patent Gesellschaftmit Beschrankter HaftungInventors: Hanns Wurziger, Michael Schmelz, Norbert Schwesinger

Patent number: 6592127Abstract: An air purged shaft seal assembly has a seal housing fixedly securable to a stationary support and having a circular aperture through which a shaft can pass. The seal housing has an internal annular surface defining the circular aperture, the internal annular surface having a first annular portion for engaging an outer surface of an annular sealing member and a second annular portion shaped to partially form an air receiving chamber. The seal housing has a passage for supplying air under pressure from an external source thereof to the air receiving chamber. A sleeve mountable on the shaft for sliding movement therealong, the sleeve having an external peripheral surface with a first peripheral portion co-operable with the first annular portion of the internal annular surface of the seal housing to receive the annular sealing member therebetween and a second peripheral portion co-operable with the second annular portion of the internal annular surface of the seal housing to form the air receiving chamber.Type: GrantFiled: January 23, 2002Date of Patent: July 15, 2003Assignee: Phlaver Inc.Inventors: Arnold B.

Patent number: 6554523Abstract: A hydraulic connector assembly is provided to couple an extension rod to a piston rod in a reciprocating pump. The connector assembly utilizes a single hydraulic ram to provide the compressive connecting force between the two rods. The connector assembly includes a mechanism for mechanically locking the hydraulic ram in place so that loss of hydraulic power does not uncouple the assembly. The piston rod and the connector rod can be coupled and uncoupled without the use of heavy wrenches, hammers, or impact tools.Type: GrantFiled: April 27, 2001Date of Patent: April 29, 2003Assignee: National-Oilwell L.P.Inventors: James C.

Patent number: 6457687Abstract: The mechanism for mounting and venting an enclosure which includes a mounting bracket which is mountable to an outdoor enclosure having an inner portion. The mounting bracket has an exterior and an interior surface. The interior surface has a mounting aperture for receiving a securement member and a venting aperture in fluid communication with said interior portion of the outdoor enclosure. Further, the mounting bracket has a bottom containing at least one vent hole in fluid communication with the venting aperture for permitting the passage of air between the interior portion of the outdoor enclosure and a space outside the enclosure.Type: GrantFiled: July 19, 1999Date of Patent: October 1, 2002Assignee: Avaya Technology Corp.Inventor: Bassel Hage Daoud

Patent number: 6394032Abstract: The present invention relates to a device for simulating static load of a connection to a ventilated rack of animal cages when at least one of the racks are not connected to a central ventilation system. Accordingly, the device assures that the ventilation system is balanced when one or more of the ventilated racks are removed from their respective air supply or exhaust drops of the central ventilation system. The device includes a pair of spring biased legs which automatically close when a rack is removed from the central air system. The legs have an outwardly curved shape at one end forming an opening between the first and second leg. In the closed position, ends of the legs are adjacent to one another such that the distance between the legs is reduced, thereby creating a partial obstruction to air flow in the connection which is identical to the static load created by the ventilated rack.Type: GrantFiled: March 3, 2000Date of Patent: May 28, 2002Assignee: Allentown Caging Equipment Co., Inc.Inventors: Michael A. Coiro, Sr., Frank J. Herdt, Brian M. Bilecki
