Title: Pipe Cutting Machine
Inventor: BABB LARRY F
IPC: B23D21/00
Filed: 1993-09-23
Abstract: A portable pipe cutting machine comprises a frame, an arm having opposite ends and supported on the frame for piv-otal movement about a pivot axis between the opposite ends, a cutting wheel rotatably mounted on one of the ends of the arm, and a hydraulic piston and cylinder unit between the frame and the other end of the arm for pivoting the arm to displace the cutting wheel toward a pipe to be cut which is supported on rollers mounted on the frame beneath the cut-ting wheel.  A manually operable variable displacement pump delivers fluid under pressure to the piston and cylinder unit to displace the arm toward the pipe, and an electric drive motor unit is supported on the arm for displacement therewith and includes an output end axially slidably inter-engaged with a drive shaft for the cutting wheel.

Title: Screen printing method and apparatus
Inventor: MILLER MICHAEL J
IPC: B41J2/005
Filed: 1993-10-04
Abstract: A composite stencil screen assembly including a uniformly-prestressed resilient backing screen attached to a frame and a metallic wire mesh stencil screen attached to the backing screen. A predetermined portion of the backing screen is removed after the stencil screen is attached thereto in order to permit the pre-stressing force in the backing screen to uniformly pre-stress the stencil screen in all directions to impart a tight, wrinkle-free, high-quality printing surface to the stencil screen. In a preferred embodiment, the assembly is retensioned subsequent to removal of the predetermined portion of the backing screen. The composite construction is uncomplicated in design, resists metal fatigue of the wire mesh stencil screen, is effectively used in non-thermally dependent and thermally dependent printing operations, and has a long service life.

Title: Syringe Having Needle Isolation Features
Inventor: BITDINGER RALF V
IPC: A61M5/32
Filed: 1993-11-26
Abstract: A hypodermic syringe has a syringe barrel with a distal end and a passage therethrough communicating with  a  fluid-receiving  chamber  in  the  syringe barrel.   A  barrier  extends  across  the  passage  to isolate the fluid in the chamber.  A needle cannula is mounted to a needle hub slidingly engaged at the distal end of the syringe barrel.  The needle cannula includes a proximally facing point for piercing the barrier in the passage to the chamber of the syringe barrel.  A needle shield is mounted to the distal end of the syringe barrel, and cam means are provided for cam-guided  rotational  movement  between  the  needle shield and the syringe barrel.  The cam shape causes the  needle  shield  and  the needle cannula to move proximally  for  initially  piercing  the  barrier  and then to move distally to  enable separation of the needle shield.

Title: Split eyebolt for spinal rod
Inventor: ASHMAN RICHARD B
IPC: A61F2/44
Filed: 1992-12-03
Abstract: The eye and threaded shaft of an eyebolt (46) are formed by a combination of two shell-like portions (46A, 46B), each having threaded bosses (48A, 48B) at distal ends thereof. The distal ends are placed around a spinal rod (14) simultaneously with insertion of one of the shell-like portions through the yoke (27, 28) of a spinal hook (22). Then the bosses are brought toward each other and the two bosses combine to form a bolt onto which a nut (36) is threaded to clamp the eyebolt, and thereby the hook, tightly on a spinal rod. The two threaded bosses have an interfitting rib (51) and groove (49) to maintain alignment of the threads of the two bosses. The eyebolt of this invention allows a connecting hook to be installed on a spinal rod in situ between other devices already installed on the spinal rod.

IPC: A47C7/40
Filed: 1994-08-05
Abstract: An improved seat back height adjustment mechanism for a chair is disclosed.  The improved height adjustment mechanism includes a U-shaped mounting bracket having a back wall and two side walls. A longitudinal shaft having a handwheel is rotatably mounted in the bracket between the side walls and spaced from the back wall.  A seat back support arm is insertable through the bracket between the shaft and the bracket back wall.   A back plate provided with a rack and an adjacent planar surface both extending along the length of the back plate is mounted onto the seat back support arm. In one aspect, the shaft is provided with a pinion for engaging the rack and a multi-sided, symmetrical cam adjacent the pinion for locking the shaft against free rotation.          When assembled, the rack and the planar surface of the back plate are aligned with the pinion and cam respectively.  When the shaft is rotated via the handwheel, the pinion rotates and engages the rack thereby causing the seat back support arm to be vertically displaced with respect to the mounting bracket.  When a planar face of the cam is contiguous with the planar surface of the back plate shaft rotation is resisted thereby locking the height adjustment mechanism.

Title: Method of cutting high strength materials with water soluble abrasives
Inventor: SURJAATMADJA JIM B
IPC: B24C11/00
Filed: 1994-11-10
Abstract: Abstract of the Disclosure Method of forming openings in structural substrates, especi-ally oil and gas well casings, by providing a supply of a pre-selected liquid and providing a supply of preselected abrasive particles which are soluble in the liquid. The liquid and abrasive particles are combined to form an abrasive particle laden saturated solution having a predetermined concentration ratio exceeding the saturation point of the base liquid. The abrasive particle laden saturated solution is then pressurized to a predetermined delivery pressure and is routed to at least one jetting nozzle capable of expelling the abrasive particle laden saturated solution. The substrate, in which an opening is to be formed, is subjected to a directed expulsion of the abrasive particle laden saturated solution at a distance and for a period of time necessary to form an opening there-through. Such abrasive particle laden saturated solution used and needed to form the opening is then considered to be re-sidual. Preferably the method further includes diluting the residual abrasive particle laden saturated solution with the original liquid, or alternatively, a second liquid such as an said, to transform the residual solution into having essenti-ally a zero concentration of soluble abrasive particles there-in. Alternatively, an unsaturated solution of soluble abrasive particles may be substituted for the saturated solution, and introduced before or after the liquid passes through the jet-ting nozzle, provided the hydraulic jetting is performed prior to the particles dissolving within the preselected liquid.
