Title: Method of filling a subterranean void
IPC: E21F15/08
Filed: 1974-01-25
Abstract: 1450823 Mines DOW CHEMICAL CO 25 Jan 1974 [26 Jan 1973] 03538/74 Heading E1F A method of filling a subterranean void comprises injecting into the void 10 a carrier liquid, e.g. water or brine, in which solid particles are suspended, the mound 17 of solid particles formed in the void having a permeability to the carrier liquid of less than forty darcies. This low permeability of the mound improves the filling of the void, the suspension being capable of travelling over larger radial distances from the point of injection. The size of the solid particles, which may be sand, gravel, fly-ash, slag, limestone or waste materials, determines the permeability of the mound, and various ranges of particle size are exemplified. The carrier liquid may contain a gelling agent, such as a natural or synthetic gum or a polymer to reduce the permeability of the mound to the carrier liquid, the gelling being delayed until entry into the void. Another method of reducing the permeability of the mound includes periodically forming a filter cake, i.e. a layer of material having a permeability of about five darcies, over the mound.

Title: Improvements in or relating to automatically re-closing electric switches or circuit breakers
IPC: H01H75/04
Filed: 1935-02-06
Abstract: 451,596. Automatic-reclosing circuitbreakers. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and HEATH, A. A., Lydstep, Rowley Park, Stafford. Feb. 6, 1935, No. 3843. [Class 38 (v)] An automatic-reclosing device for a circuitbreaker comprising a spring or weight-operated driving means adapted when released to effect reclosure repeatedly until the stored energy is exhausted, has means acting in response to tripping of the breaker to release the driving means and effect reclosure after a short interval, and means which, during the closing movement comes into position to restrain the driving means from effecting a second reclosure if the circuit trips again but which, some time after the breaker has become closed, move back to the inoperative position. Fig. 1 shows a weight-operated reclosing mechanism applied to a known type of breaker which is retained closed by an overset toggle 1, 2, 4 and tripped by means of a catch (not shown), releasing the lever 4 which, under the opening bias, rotates clockwise and allows 1, 2 to collapse. The rotation of 4 also acts through a spring-plunger device 18, 19 to collapse a toggle 15, 17 against the force of a time-delay mechanism 21. When the toggle moves overcentre, the mechanism 21 is arranged to become disengaged and an abutment 13 is rotated clear of a projection 11a on a sprocket wheel 11, thereby permitting the weight 8 and chain 12 to rotate the wheel 11 clockwise. This movement acts through a pin 7 and link 9 to restore the lever 4 to its latched position and at the same time reset the toggle 15, 17 and arm 13, Fig. 3. During the further rotation of 11, the pin 7 acting through link 9 oversets the toggle 1, 2 and recloses the breaker, and also engages the slot 24a in link 24 and draws an abutment 22a into a position where it lies a little below the normal position of, and obstructs, the projection 11a, Fig. 5, until a weight 27 acting against a time-delay mechanism 26 moves it clear again. The delay introduced by the latter is considerably longer than the interval between tripping and reclosure, so that if tripping occurs again before the expiry of this delay, as would happen with a permanent fault, reclosure is considerably delayed or preferably prevented. For preventing reclosure, either the frictional force between 11a, 22a when the former moves down onto the latter, is arranged to be sufficient to resist the biassing force of weight 27, or the thrust on the lever 22 is arranged to act on the side of pivot 23 remote from the weight. Manual resetting is effected by extension 22b. For limiting the actual number of reclosures, the weight 27 is obstructed by a member 38, which is actuated by a counterweight 32 engaging a cam 35 when the weight is near its lowest limit. A handle 33 or electric motor drives a sprocket 29 through a worm gear 34 to wind up the weight 8.
