Abstract: A rotational moulding machine includes three mould manipulator arrangements and a rotatable carrousel on which the manipulators are mounted for indexed rotation between heating, cooling and mould loading stations. Each manipulator includes a rectangular frame, stub axles on the frame which are rotatable in supports on the carousel on a first axis, mould locating element in the frame which is rotatable on a second axis normal to the first and devices for manipulating a mould in the frame on both axes. The machine includes a crane beam over the carrousel which overlies the heating and cooling station positions on the carrousel, a heating chamber, a wall enclosure, and a crane for lowering the heating chamber and wall enclosure over manipulators on the carrousel at the heating and cooling stations and for lifting them clear of the manipulators to enable them to be indexed to the next station.

Abstract: A coil support apparatus is provided that is configured for supporting a moveable coil within a magnetic field in a voice coil motor. The apparatus comprises a support arm with a characteristic cross section defining a first portion with a thickness related to a thickness of the coil for providing a mounting surface for attaching the coil. The support arm further defines a discontinuous second portion extending from the first portion in a direction away from the coil with a thickness substantially smaller than the first portion thickness. In some embodiments an actuator assembly is provided comprising a T-beam coil support.

Abstract: In a data handling system having a radially-dependent track incongruity between data surfaces, at least some tracks are logically mapped so that tracks on different data surfaces correspond with one another. The correspondence is defined by the mapping so as to shorten an average headswitch seek. For example, a logical track mapping of first and second non-coaxial track sets can be defined so as to optimize a headswitch seek within each of many intermediate logical cylinders identified in the mapping.

Abstract: This invention relates to a fluid transfer system including two elongated fluid transfer chambers, fluid inlet and outlet arrangements at each end of each chamber, oppositely directed one-way inlet and outlet valves in the inlet and outlet arrangement at a first end of each chamber for controlling the flow of a driven fluid into and out of the chamber, oppositely direted inlet and outlet controlled valves in the inlet and outlet arrangement at the second end of each chamber for controlling the flow of a drive fluid into and out of the chamber, a pressure balancing arrangement including a port in each of the controlled valves, an actuator on each controlled valve which is adapted to open and to close the valve and the pressure balancing port in the valve, and a control system which is connected to the actuators of each of the controlled valves for proportionally opening and closing the controlled inlet valves of each chamber in exact opposite phase to each other and for opening and closing the controlled chamb

Abstract: There is provided a tool joint having a box and a pin wherein the box has threads therein; and wherein the box and the pin each are provided with complementary surfaces which engage one another upon threading of the box and the pin together.

Abstract: A method and system are disclosed for selectively altering the functional characteristics of a data processing system without physical or mechanical manipulation. A data processing system is first manufactured having a predetermined set of functional characteristics. A multibit alterable code which includes a functional characteristic definition is then initially loaded into physically secure, nonvolatile memory within the data processing system, utilizing an existing bus, or a fusible link which may be opened after loading is complete. The functional characteristic definition is loaded from nonvolatile memory into a nonscannable register within a secure portion of a control logic circuit each time power is applied to the data processing system and the definition is then utilized to enable only selected functional characteristics.

Abstract: Electrical characteristics of the inputs to VLSI semiconductor chips can be modified after the chips are fabricated and mounted into multichip modules (packages), at which time the required characteristics are known accurately. The changes are accomplished by incorporating special circuitry at the chip inputs during their design combined with the use of `boundary-scan` type circuitry that has recently been put in place for device testing. The circuitry allows the impedance characteristics of the chip's receiver to be modified to match that of the driving source and the wiring interconnections between the chip and source. The test circuitry is used to provide the logical signals to selectively switch the circuits to the proper configuration. This enables optimally designed interconnections between the input and output circuitry on the chips and thereby avoids the necessity for costly re-designs.
