A method and system are disclosed for moving equipment into and through a conduit that is preferably an oil and/or gas production well, wherein use is made of an uphole equipment storage and handling unit via which equipment modules can be moved into a launch conduit and connected to a shuttle device which is able to locomote itself as a wireless tractor via the launch conduit into and from the underlying conduit.
摘要:
A method and system for measuring data in a fluid transportation conduit, such as a well for the production of oil and/or gas. The system employs one or more miniature sensing devices which comprise sensing equipment that is contained in a preferably spherical nut-shell which has an outer width which is smaller than the internal width of the conduit. One or more sensing devices are released sequentially in the conduit and are induced to move in longitudinal direction through the conduit to measure data at desired intervals of time, without requiring a complex infrastructure.

A binding apparatus having a base portion and a binding mechanism is disclosed which binds a stack of punched paper sheets with a plastic binding element having an elongated linear spine and integral spaced resilient curled fingers extending from the spine. The binding mechanism includes a fixed binding comb and a series of push fingers. The binding comb has a series of upstanding fixed spaced pickets having sufficient clearance between each other to allow the binding element curled fingers to be manually shifted laterally relative to the fixed pickets such that each of the curled fingers surrounds a portion of the push fingers. The binding mechanism also has a device for moving the push fingers outwardly from the pickets to uncurl the curled fingers so that a stack of punched paper sheets can be placed on the uncurled fingers.

A bolt assembly (21) including a movable bolt (34) and a user manipulatable bolt displacement assembly is disclosed. The bolt displacement assembly moves the bolt (34) between a locked and an unlocked position. The bolt displacement assembly includes a user manipulated handle (37), a torque transfer assembly (b 38) and an electromagnet (39). Handle (37) is mounted on an exterior side (36) of the bolt assembly (21) and is freely movable without coupling of the handle (37) to displace the bolt (34). Torque transfer assembly (38) in the form of a rocker arm (63) is mounted for movement in response to movement of the handle (37) and moves to and from a torque transmitting position during at least part of the movement cycle of the handle (37). Additionally, electromagnet (39) is reponsive to user input for energization thereof and is positioned to magnetically hold the torque transfer assembly (38) in the torque's transmitting position upon the simultaneous occurrence of energization of the electromagnet (39 ) and movement of the torque transfer assembly (38) to the torque transmitting position by the handle (37). Handle (37) is further movable by the user while the torque transfer assembly (38) is held in the torque's transmitting position to couple the handle (37) to bolt (34) to move the bolt (34) between the locked position and the unlocked position. Additionally, an optic link (29, 32) coupling dead bolt assembly (21) to an electronic door lock assembly (23) is provided so that input to the door lock assembly (23) automatically energizes the electromagnet (39) in the dead bolt assembly (21) to permit opening of the dead bolt assembly (21).
摘要:
A paper punch and binding apparatus has two punch mechanisms, one for punching round holes in a paper sheets stack and one for punching rectangular holes in another paper sheets stack. A single lever or crank simultaneously operates and drives a series of round end punches to shear the round holes and a punch plate with integral rectangular punch elements shear rectangular holes. A four-bar linkage connects the lever to the punch plate and the series of the punches in a manner that both the plate and punches are driven in a vertical straight line and with a greater mechanical advantage at the start and over the first increments of the punching operation. In a preferred embodiment, a binding station is provided in an apparatus base portion particularly for binding with a Douvry-type plastic resilient loops binding element. The binding station has an operating knob which operates a simple gear interconnect train for uncurling the resilient loops and allowing the punched hole stack to be inserted thereon. In an additional embodiment two rows of large and smaller diameter punches are provided in one round punch mechanism with an apertured translatable bar for rendering inoperative one or the other of these rows of punches.

An improvement to an air logic circuit for an airfeed peck drill includes the insertion of an advance valve into the timer circuit. This advance valve generates a signal to actuate the timer circuit only after the drill quill has fed forward through rapid advance.
