Title: A rotatable pressure seal
Inventor: COLEBROOK MARK ANTHONY
IPC: E21B7/04
Filed: 1995-06-01
Granted: 2007-08-14
Abstract: A rotatable pressure seal between a relatively rotatable shaft and body structure comprises two annular sealing discs concentric with the shaft, one disc being mounted on the body structure and the other disc being carried on the shaft, the discs having engaging sealing faces formed of polycrystalline diamond or other superhard material. The pressure seal is particularly for use in a modulated bias unit, for controlling the direction of drilling of a rotary drill bit when drilling boreholes in subsurface formations. The bias unit comprises a number of hydraulic actuators spaced apart around the periphery of the unit, and a selector control valve modulates the fluid pressure supplied to each actuator in synchronism with rotation of the drill bit so that, as the drill bit rotates, a thrust member of each actuator is displaced outwardly at the same selected rotational position so as to bias the drill bit laterally and thus control the direction of drilling. The selector control valve is located within a cavity in the body structure and is operated by a shaft which extends into the cavity through a pressure seal according to the invention.

Title: Jumper tracing system
Inventor: COHEN LEONARD GEORGE
IPC: H04Q1/14
Filed: 1995-11-09
Granted: 2000-03-21
Abstract: The present invention includes a system for tracing jumpers used in an exchange to cross-connect optical fibers or wires served by the exchange. The system includes an exchange housing receptacles with optically-encoded data associated with eachreceptacle or a group of receptacles. The optically-encoded data for a receptacle(s) uniquely identifies the physical location of the receptacle from any other receptacle in the exchange. Also, this optically-encoded data can include the type of jumper and/or length of the jumper to be used with the receptacle, the correct routing of the jumper through the exchange, the traffic to be carried on the jumper and/or the identity of the physical location of the receptacle to be connected to the other end of the jumper. Likewise, the jumpers each have optically-encoded data formed thereon that uniquely identifies the jumper or jumper end and distinguishes the jumper from any other jumper used in the exchange. The optically-encoded data associated with the jumper can include the type of jumper, the length of the jumper, the proper routing of the jumper through the exchange and/or the traffic to be carried on the jumper. If no jumper is to be connected to a particular receptacle, a cover with optically-encoded data can be attached to a receptacle to indicate that no jumper is connected to the receptacle. The system of this invention also includes a hand-held optical scanner that can be used by an operator to scan the optically-encoded data associated with a receptacle(s) and the optically-encoded data of a jumper(s) connected to the receptacle(s), and transmits the optically-encoded data signals to a computer of the system of this invention. The computer can generate a display of the physical location of a receptacle(s) in association with the identity of the jumper(s) and connected thereto, so that an operator can diagnose misconnections of the jumpers between receptacles in the exchange. Further, the computer can store verification data that can be compared with optically-encoded data signals from scanning with the optical scanner, to determine whether the proper jumper has been connected to a receptacle, whether the jumper is of appropriate type or length for the cross-connection and whether the jumper or receptacle is associated with traffic that is of interest to the operator, for example.

Title: Virtual addressing buffer circuit
Inventor: KIM JASON SEUNG-MIN
IPC: G06F12/10
Filed: 1994-10-04
Granted: 2002-07-30
Abstract: A virtual addressing buffer circuit (10) formats an output address utilizing a format register (16) as a combination of new address bits and original input address bits. The ability to format the output address enables the user to replace certain address bits without requiring that the entire address be replaced. The virtual addressing buffer controls the output of several command signals to external circuits to indicate how the system should respond to the address output from the virtual addressing buffer. The command signals are controlled by a command register (20) and are output from the virtual addressing buffer only when an address match has been verified. The virtual addressing buffer circuit filters out certain bits of an input address as indicated by a filter register (22) before it verifies that the input address matches a stored address. Once an address match has been detected, the virtual addressing buffer circuit replaces the entire input address with a new formatted address.
