Abstract: The invention provides an apparatus that holds and tilts a tool over a tilt range and substantially about a vertex. The apparatus includes a base having pivots defining a base line and a base pivot distance. The apparatus also includes first and second pivot arms coupled to the base pivots, and a tool holder having pivots coupled to the first and second pivot arms. The tool holder pivots defining a tool holder line having a pivot distance different than the base pivot distance. The tool holder is arranged for holding the machine tool. An intersection of the base line and a selected pivot arm defines a control angle, such that changing the control angle changes a tilt of the tool holder with respect to the base line, and correspondingly tilts a longitudinal axis of the tool substantially about a vertex.

Abstract: The invention is directed to a wire cutting and stripping and terminal attaching apparatus and, in particular to an improved wire positioning mechanism for positioning the stripped end of an insulated wire in an open barrel terminal. After the insulated wire is cut and a slug of insulation is removed from the end of the wire, a gripper rotates the wire so that the bare or stripped end of the wire is located above an open barrel terminal supported on a lower die of a terminal attaching unit. An upper die is movable on the terminal attaching unit in a direction toward and away from the lower die to crimp the terminal on the stripped end of the wire. The wire positioning mechanism includes a positioning member which is mounted on the upper die and arranged to contact the gripper and push the stripped end of the wire downwardly into the open barrel terminal before the upper die operates to crimp the terminal.

Abstract: A system for controlling motion in machine tools and industrial robots. From the specification of a part to be cut or a path to be followed by a machine tool or a robot, the system calculates, for each axis, for each incremental step along the path, a position command, a time delay between successive position commands, and, optionally, a force command based on a prediction of predicted resistive forces. Calculations are specified for precisely controlling velocity, acceleration, and jerk. The generated data is stored in a memory device and subsequently directed to the machine tool or robot.

Abstract: A machine tool apparatus, and a linear motion track therefore, are disclosed where the linear motion track is comprised of a tube having a circular cross-section with at least two bearings longitudinally disposed on opposite exterior sides of the tube such that the tube forms a pair of arches joined by the two bearings. The tube arches minimize localized bending moments when radial or moment loads are applied to the tube arches through the bearings and from the longitudinally slidable carriage on the tube. In addition to the linear motion track, the machine tool apparatus also includes a table, for supporting a workpiece, to which the linear motion track is attached, and a machine tool attached to the linear motion track.

Abstract: A pressure compensation device for use in a high-pressure direct driven pump to control the output pressure of the pump is shown and described. In a preferred embodiment, the high-pressure pump has a valve assembly that selectively allows fluid pressurized by a reciprocating plunger to pass from a pressurization chamber to an outlet chamber from which the pressurized fluid is collected for use. A pressure compensation device has a lever which balances a control force against a force generated by the high-pressure fluid in the outlet chamber. When the outlet pressure exceeds a selected level, the pressure compensation device acts to prevent the further pressurization of fluid by causing the fluid to flow back out of the pressurization chamber via the same passageway(s) through which the fluid was originally introduced into the system.

Abstract: An apparatus to remove rubber from airplane tires from an airport runway surface. there is a manifold arm which rotates at as high as two thousand five hundred rpms over the runway surface, with a plurality of water jets being discharged downwardly at a relatively high pressure (e.g. thirty five thousand P.S.I.) against the runway surface. Even though the water pressure is at a level several times higher than that at which damage to the runway surface can occur, at the relatively high linear speed of the water jets (e.g. ninety to one hundred eighty miles per hour), there is no noticeable damage to the runway surface, but yet there is quite effective removal of the accumulated rubber. Also disclosed is a particular shaft and seal assembly which is capable of operating at relatively high rotational speeds and delivering the high pressure to the manifold arm.

Abstract: A high pressure liquid jet abrasive cutting apparatus having a removable and replaceable cartridge assembly. This cartridge assembly has a nozzle unit with a jewel orifice, an intermediate mixing chamber where the liquid jet and the abrasive particles mix, and a discharge tube through which the liquid jet incorporating abrasive particles therein is discharged. The nozzle unit and the discharge tube are preassembled in a cartridge housing at a factory location under controlled conditions, so that precise alignment is obtained. Replacement of the worn parts is accomplished by interchange of the cartridge assembly.

Abstract: A seal assembly having a backup ring through which a piston reciprocates. There is a seal sleeve made of a non-abrading, extrusion resistant material that surrounds the piston at a location forwardly of the backup ring. The backup ring has an opening to receive the piston, and the opening is formed to define a radially and rearwardly expanding gas between the piston and backup ring to receive and discharge any seal material which may extrude into the gap. There is a positioning flange integral with the backup ring that surrounds the seal sleeve to press the seal sleeve into engagement with the piston, and there is an outer seal portion to form a seal between the positioning flange (or the outer portion of the backup ring) and the cylinder.

Abstract: A linear alternator/motor which is capable of translating the energy of linear mechanical motion into electrical energy, and/or also transforming electrical energy into linear mechanical motion. There is an inner pole member and an outer circumferential pole member defining first and second annular gaps. An armature component comprising first and second coil sections, positioned in the gaps, reciprocates relative to the the pole members. The coil sections have current flowing therein so that field portions of these coils coupled into the main magnetic field substantially cancel each other as the coil selections move between end positions.

Abstract: An overall pump assembly for smoothly pumping a compressable liquid from a supply is disclosed herein along with two intensifiers which form part of the assembly and a control arrangement for driving the intensifiers in specific phase relationship to one another. Each of the intensifiers includes its own reciprocating piston and a control device interconnected in feedback relationship with the piston in order to follow the latter through its movement. In each of the specific intensifiers disclosed, its piston and control device are interconnected by cable means configured to cause the control device to rotate about its own axis in a manner corresponding to the movement of the piston.

Abstract: A high pressure hose fitting which includes a crimpable sleeve for use over a hose and a conical ferrule that separates the cord layer of the hose from the inner linings and clamps the cord layer ot the sleeve. A housing enclosed the fitting and provides the clamping force. An O-ring between the ferrule and the housing aids in sealing. All parts are so designed that an increase in pressure increases the sealing force and clamping force.

Abstract: A swivel fitting arrangement for use in a pressurized fluid line, especially a high pressure, high flow rate line, is disclosed herein and utilizes first and second adjacent sections of the line in coaxial and unconnected relationship to one another so as to define an axial joint between the two sections and such that the first section is able to rotate aboout its axis relative to the second section. The arrangement also includes means for supporting the two line sections in their coaxial and unconnected relationship with one another and a tubular sealing member disposed coaxially within the line and across the axial joint between and directly against the adjacent sections and joint for internally sealing the joint while allowing fluid within the line to pass from one of the sections to the other.

Abstract: An ultra-high pressure hose assembly capable of withstanding sustained internal fluid pressures exceeding 60,000 psi is disclosed herein and consists essentially of an innermost tubular core, a plurality of successive tubular layers and an outer containment sleeve. The innermost tubular core and containment sleeve are designed to add substantially no structural integrity to the overall assembly but rather function only as a fluid barrier and containment structure for the tubular layers respectively. The outer tubular layers serve as structural members of the overall assembly and respectively consist of individual bands which are alternately helically wound around and directly against the layers immediately below them at predetermined helix angles. Each band in turn consists of a number of separate steel wires which have opposing flat sides and which are positioned in unconnected edge to edge relationship to one another so as to form the band.

Abstract: A digital data transmission system eliminates the need for coaxial cable or twisted pairs as a means to eliminate noise, interference or cross talk problems. The system utilizes a multi-conductor cable having a plurality of lays of insulated conductors surrounded by an electrically conductive shield. The shield serves as a common ground and one conductor in each lay provides a reference line for that lay. Data is transmitted over lines in at least one lay, the lines for transmitting data being terminated at each cable end by their characteristic impedances with respect to the shield.

Abstract: A piston and a cylinder within a pump housing cooperate with the inner walls of the housing to form a high-pressure reservoir surrounding the cylinder to provide a continuous compressive force thereon to prevent tensile stresses in the cylinder during pumping operations to prevent failure of the cylinder due to metal fatigue. A check valve between the cylinder and the reservoir permits high-pressure fluid to flow from the cylinder into the reservoir during pumping operations to maintain substantially the maximum cylinder pressure within the reservoir. The cylinder further includes therein an inlet with an associated check valve. Stationary seals in the pump use the high pressures in the cylinder and the reservoir for producing the sealing forces necessary to prevent leakage. The primary piston seal consists of a long, controlled clearance gap which permits a small leakage but has only minor contact and thereby low sliding stresses and a long life.

Abstract: A fluid jet cutter using an articulated boom support system is disclosed. The cutter utilizes a support system which allows rotational translation in all three axes. The boom system allows displacement of the cutter over a broad area. A jet catcher is attached to the cutter head to catch the cutting jet. A deadman switch arrangement prevents the operator from contacting the cutting jet. A vacuum system is linked to the catcher and a column that supports the boom to remove cutting debris and waste fluid.

Abstract: A seal for a movable shaft which extends from a cavity within a high-pressure vessel maintains a uniform gap between the shaft and the seal body at high pressures to form an effective seal while providing adequate clearance between the shaft and the seal body to prevent excessive wear.
