Title: Process for the driving of a tunnel and tunnel borers therefore
Inventor: PAURAT FRIEDRICH W
IPC: E21D9/00
Filed: 1993-10-01
Abstract: ABSTRACT      A process for the driving of a tunnel into geological rock formations including hard rock obstacles includes the steps of cutting rock in forward direction from the head wall of the tunnel being driven, stopping the cutting operation when a hard rock obstacle is encountered, firing an explosive charge at the hard rock obstacle encountered for disintegration thereof and removing the disintegrated hard rock.  A self-propelled tunnel borer is used which includes a loose rock removal arrangement.  The tunnel borer includes at least one explosive charge launcher which is loaded with an explosive charge.  When a hard rock obstacle is encountered in the head wall, the explosive charge launcher is aimed at the obstacle and the explosive charge fired at the obstacle for the disintegration thereof.  The size and type of the explosive charge, the distance of the explosive charge from the hard rock obstacle upon detonation (blasting) and the explosive charge detonation itself are selected in such a way that the disintegrated hard rock can be removed with the rock removal arrangement of the tunnel borer.  Thus, when a hard rock obstacle is encountered, it is no longer necessary to back the borer off the head wall for the employment of special obstacle removal equipment so that the cost and time associated with the tunnel driving operation are reduced.

Title: Signaling Method for Packet Network and System
Inventor: IWATA ATSUSHI
IPC: H04L12/721
Filed: 1993-12-24
Abstract: A method which achieves a reduction of the virtual channel connection delay time in signaling without using permanent virtual channels (PVC) and without performing wasteful allocation of signal bandwidth. When a transmission terminal transmits a packet, a packet transmission control section requests transmission of a signaling packet to a signaling transmission section. The signaling transmission section searches a VC and signal bandwidth table and sends out, when a virtual channel is registered and a required signal bandwidth is provided, a packet using the virtual channel. When the signal bandwidth is insufficient, it requester from the packet switching system only a sufficient signal bandwidth and then sends out the packet. When no virtual channel is registered, the signaling transmission section requests a signaling packet from the packet switching system. The table includes, for each destination address, a virtual channel timer for releasing the virtual channel applied thereto after the virtual channel is held for a predetermined period of time after completion of transmission, and a bandwidth timer for reducing the signal bandwidth after each predetermined interval of time after the completion of transmission. At each end of a packet transmission, the two timers are reset to a clock.

Title: Method of improving the contaminant resistance of a smectite clay by rewetting and impregnating the clay with a water-soluble polymer, and redrying the polymer-impregnated clay
Inventor: KAJITA LAURA
IPC: C02F1/28
Filed: 1994-09-01
Abstract: ABSTRACT            A method of treating a water-swellable clay after the clay has been mined and dried to improve its properties when in contact with contaminated water. After the common initial drying of the clay to a moisture content of 12% by weight or less, the clay is impregnated with an aqueous solution containing a dissolved, water-soluble polymer, in an amount of at least about 0.5% by weight based on the dry weight of the clay, and the clay is wetted to a moisture content of more than 12% by weight, preferably at least about 15% or more, based on the dry weight of the clay, and then redried to a moisture content of 12% by weight or less, based on the dry weight of the clay.  This rewetting step to hydrate and polymer-impregnate the clay, and then redrying the clay, unexpectedly improves the contaminated water absorbency, and viscosity properties when the clay is in contact with contaminated water; unexpectedly increases the rheology properties of the clays for oil well drilling fluids and lost circulation fields when contaminated water is encountered during drilling, enhances the clay properties when used as a suspending agent in the cosmetics and pharmaceutical industries when the composition contains a dissolved, inorganic salt and/or an organic liquid; and provides unexpectedly increased contaminated water-absorption in forming water-swellable clay-based water barriers.
