International Classification:

E21C 41/22

US Classification:

299 18, 299 19

Abstract:

In the method according to the invention and the arrangement or according to the invention for extracting extraction products in underground mining operations using the caving method, the extraction products () collapsing in an upper gate area () are extracted via at least one extraction funnel () or the like into an extraction path () driven below the gate and are transported away therein by means of an extraction conveyor (). According to the invention the extraction funnels () are arranged laterally beside the extraction conveyor () and lead at their lower end into a ramp surface () inclined towards the extraction conveyor, the extraction products extracted from the gate through the extraction funnels being transported slidingly over the inclined ramp surface to the extraction conveyor. The inclined ramp surface is preferably formed by a loading ramp () which is so arranged in an extraction chamber () branching off laterally from the extraction path that its one end (), disposed higher, is located below the extraction funnel and its other end (), disposed lower, forms an outlet () towards the extraction conveyor.

International Classification:

B65G 65/14

US Classification:

1983081, 198309, 1984632, 299 18

Abstract:

An arrangement for extracting extraction products in caving in which the extraction product is extracted downwards through an extraction funnel into an extraction path and from this is transferred onto an extraction conveyor arranged in a conveyor path, in which arrangement the extraction path extends transversely between the conveyor path and an auxiliary path parallel to this, a loading ramp is arranged in the extraction path which forms a ramp surface orientated transversely to the conveying direction of the extraction conveyor and inclined towards it. The extraction path is provided with a rail guidance attached to the bottom and extending in the area between the auxiliary path and the conveying path, on which the loading ramp is guided and along which it can be moved by a displacement drive () in the direction of the conveyor path and in the opposite direction.

Appl. No.:

5/661590

Inventors:

Harry F. Martin - Media PA

Assignee:

Westinghouse Electric Corporation - Pittsburgh PA

International Classification:

F16K 31122

US Classification:

251 26

Abstract:

A free floating disc valve having a positive closure arrangement thereon. A containment vessel enclosing a volume communicable with a pressure chamber is disposed above the valve disc and permits introduction into the pressure chamber of a high pressure fluid entrapped within the containment volume to provide a force to assist the seating of the valve disc.

Martin E. Schlatter - Glen Mills PA

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

F01D 514

US Classification:

415116

Abstract:

Several means for providing superheated steam varying in pressure and temperature in a plurality of cavities serially disposed between blade discs of a steam turbine in which steam flows from a high pressure to a low pressure portion and improved seals disposed at the radially outer periphery of the cavities which cooperate with the means for providing superheated steam in the cavities to eliminate moisture in the cavities and eliminate stress corrosion in the blade discs.

Appl. No.:

8/439365

Inventors:

Harry W. Martin - Palm PA

International Classification:

B65D 9100

US Classification:

232 17

Abstract:

A mailbox unit comprising a hollow housing member mounted on a support member affixed to a base. Hinges are connected to the housing member and support member for allowing the mailbox to tilt upon being struck by a damaging lateral force. The base has a bottom that comprises a beveled outer portion that converges downward defining a generally conical shape with a flat center portion which permits the mailbox unit to rock after being subjected to a damaging lateral force.
