Inventor: PERLMAN WILLIAM
IPC: E21B43/27
Filed: 1987-06-17
Abstract: An improved method of multiple-stage hydraulic fracturing of coal seams to improve the rate and total recovery of gas therefrom. In one aspect, the improvement comprises completing the well with 7-inch or larger casing and 31/2 inch or larger tubing. In another aspect, the stagewise fracturing is continued until the following quantity of 60-140 mesh proppants has been deposited in the formation: -for 5 </= h < 10, m >/= 500,000; -for 10 </= h < 15, m >/= 750,000; -for 15 </= h < 20, m >/= 1,000,000; -for 20 </= h < 25, m >/= 2,000,000; and -for h >/= 25, m >/= 3,000,000; -  wherein h is the vertical thickness of the coal seam in feet and m is the minimum quantity of the fine proppants in pounds deposited therein. In another aspect, a coal seam fractured by the multiple-stage method is refractured after producing or shutting in the well for a period of time to permit closure of the fractures on the proppant placed therein in the earlier multiple-stage fracturing of the coal seam.

Abstract: Apparatus for multiplexing a coherent high power CW laser beam has a mirror mounted on a galvanometer to interrupt the laser beam and another mirror mounted on another galvanometer to deflect the laser beam to a selected pair of optical fibers. The other mirror is moved only when the laser beam is interrupted to avoid fiber damage. Yet another mirror mounted on a galvanometer can be used to provide a greater number of addressable fibers. A method of multiplexing comprises interrupting a laser beam, deflecting it, changing its direction only when interrupted, focussing it, and transmitting it through the optical fibers.

Patent SE-9400001-L (SE)
Inventor: SILLEN RUDOLF VALENTIN
IPC: G01J5/04
Filed: 1994-01-03
Abstract: The method is for the contact-free, continuous temp. measurement of the hardening process of metal alloys, and involves the smelt, which is to be analysed, made to rotate around a vertical axis in a cylindrical and concentrically placed test body (2), with measurement of the temp. being effected with the aid of an optical temp. meter (6). With rotation, a parabola-shaped inner surface is formed, and the temp. measurement is effected on a part of the parabola upper limiting surface (5). The test body has a circular form, pref. made of core sand or other suitable material with an inner concentrically placed cylinder, whose height coincides with the desired height of the smelt in the test body outer part. Measurement of temp. occurs simultaneously on two different height levels in the parabola which is so formed with the aid of speed that the levels correspond to different hardening times.

Abstract: The present invention relates to a drive mechanism (101) intended in the first instance for linear conveyors, for example lifting devices, position displacement or other actuating devices, consisting of a transmission element (103), which is so arranged as to run around deflectors (104, 107). The transmission element (103), in the form of an endless loop, runs between two end deflector arrangements (104, 107) situated at a mutual distance from one another at either end of a linear movement device and interacts with an intermediate drive component (113) acting between the aforementioned end deflection arrangements and moving relative to them, which intermediate drive component exhibits two drive elements consisting of toothed wheels or chain wheels (40, 41) with different numbers of teeth. Gearing is achieved in this way through the difference in the speed at which the transmission element (103) is fed out to either side of the intermediate drive component (113). In accordance with the invention, the gearing mechanism consists of only one pair of rigidly connected chain wheels/toothed wheels with different numbers of teeth (40, 41), or of a cable wheel with two winding-up drums which exhibit different diameters, around which the transmission element is wound in the opposite direction.

Systemet är konstruerat för spolningsaggregat för täckdiken men kan användas även för vinschar och motsvarande som bygger på en separat förrådsvinda och vinschtrumma/matningsenhet. Problemet med tidigare kända system uppstår då utmatningen plötsligt stoppas vid snabb utmatning. Då fortsätter vindan att rotera p.g.a. svänghjulseffekten med påföljd att det vindade objektet (l) rullas ut mot baksidan och riskerar att fastna i andra maskindelar då matningen fortsätter. Med denna uppfinning fungerar bromsningen av vindan (2) oberoende om matningen stoppas med manöverventilen (8) eller på grund av mekaniskt motstånd.

Abstract: <?delete-start id="DEL-S-00001" date="20080909" ?>A practice ammunition projectile comprises a head which bursts when the projectile strikes a target and contains a marking agent which optically indicates the point of impact after the head has burst. The marking agent consists of several chemical components ( 7, 8 ) which are each contained in separately breakable compartments ( 4, 5 ) within a burstable hood at the head of the projectile. When the compartments ( 4, 5 ) break open the compartments combine and undergo a chemical reaction which creates an optical mark. The hood is formed of an optically transparent material to enable the trajectory of the projectile to be tracked.<?delete-end id="DEL-S-00001" ?> <?insert-start id="INS-S-00001" date="20080909" ?>An ammunition cartridge comprising a hollow projectile and a cartridge case with a propellant charge, the projectile comprising a projectile head designed to withstand the forces applied when the projectile is fired from a gun and designed to burst when the projectile strikes a target. A marking agent is disposed in the head for optically marking the impact with the target after the head has burst. The marking agent includes a plurality of chemical components each received in a separate frangible compartment in the head. These components are mixed and react chemically with each other when the compartments break up, causing the mixed components to luminesce. The compartments are designed to be broken up by the initial acceleration and/or the centrifugal forces on the projectile when the projectile is fired from a gun, while retaining the chemical components in the head. The components are therefore mixed at the time the projectile is fired from a gun and luminesce by the time the projectile strikes the target. <?insert-end id="INS-S-00001" ?>
