Title: Re-energizable valve and valve seats
Inventor: WITT ROBERT L
IPC: F16K5/20
Filed: 1993-09-08
Abstract: ABSTRACT Disclosed is a type of valve of the sort that controls the flow of fluid and that contain a plug and at least one seat against which the plug presses to close thevalve. The novel valve has floating seats, which can seal downstream, and only when desired, can also be re-energized to seal upstream. The upstream sealing capability of the invention provides a backup against downstream leaks, such as from low-pressure flows or parts failures such as due to wear or breakage. The valve can seal upstream through the use of hydraulic fluid, which is injected athigh pressure into a sealed cavity behind the upstream seat, thereby forcing theseat against the plug. A novel seat seal design permits sealing against the fluid flow as well as isolation of the hydraulic injection ports from the fluid flow, during all operating states of the valve.

Title: Process and apparatus for the location of cable defects
Inventor: LEFELDT EKKEHARD
IPC: G01R31/11
Filed: 1994-10-18
Abstract: PROCESS AND APPARATUS FOR THE LOCATION OF CABLE DEFECTS         ABSTRACT OF THE DISCLOSURE    A process used to locate cable faults, in particular to locate non-burnout cable faults in the vicinity of branched cables.  The pulse reflection method is used and a capacitor is charged and then discharged across a spark gap by mean of spark- over at a fault in the cable.  Simultaneously with a main capacitor in an impulse wave generator, a second pulse capacitor is discharged into the cable by means of a short circuit switch. The resulting reflection wave is input via a decoupler into a first channel of a digital storage unit. After opening the short circuit switch, the main capacitor in the impulse wave generator and the second pulse capacitor are again charged and then again discharged into the faulty cable by closing the main switch.  The pulse capacitor is discharged by means of a plasma-triggered spark gap.  The spark gap is triggered by the charge of the impulse wave generator.  As a result of a delay in the formation of the plasma, the discharge pulse of the pulse capacitor reaches the fault location in the cable just after ignition.  The resulting reflection wave, with no ignition delay, is input via the decoupler to a second channel of the digital storage unit. The fault location is determined by analyzing the differences between the two recordings.

Abstract: A method of forming a burner for a gaseous mixture of fuel and an oxidant comprises mixing a random mix of refactory fibers comprising predominantly alumina and silica and then forming a burner body from the fiber mix. Passageways are then formed in the burner body by perforating the burner body with pins.  This is achieved by providing comb assemblies each having a plurality of pins, which are pressed into the body from either side and then removed, and the body is then indexed for further sets of holes to be formed.   The burner body can be treated with colloidal silica and subsequently baked to bond and preshrink the fibers, both before and after the forming of ports or passageways.

Abstract: A clock is phase shifted by an amount controlled by the value of a control signal by establishing at least several discrete delay times to be imposed on the clock. The control signal value controls selection of the imposed discrete delay time. An analog-to-digital converter of a phase locked loop responds to intelligence representing variable phase bits and the selected phase shifted clock to control the signal value.      The selected replica is derived by at least several cascaded substantially equal time delay units. In one embodiment, a multiplexer responds to the clock and the signal value, with is Gray coded, to control connections from one of the delay units to an output terminal. In another embodiment, the number of cascaded delay units interposed between the clock and an output terminal is controlled by the signal value. One use of the phase shifter is in a phase lock loop.

Title: Milking system with variable pressure source
Inventor: THOMPSON PAUL D
IPC: A01J5/007
Filed: 1992-12-01
Abstract: A milking system (10) uses a variable pressure source (82) and varies the pressure supplied to the pulsation chamber (32) along a controllably variable pressure curve of selectable waveshape.  Pulsation cycles are shortened by shortening the transition time between pressure levels providing on and off portions of the pulsation cycle. The pulsation chamber (32) is sequenced through different pressure change rates, all during the transition. Pressure transition times during pulsation cycles are varied at the beginning, middle and end of a milking interval to provide a faster rate of liner opening movement at the beginning of the milking interval to provide deeper teat penetration into the liner, and intermediate rate of liner opening movement during the middle of the milking interval, and a slower rate of liner opening movement at the end of the milking interval to limit loss of adhesion between a less than full teat and the interior of the liner.
