Abstract: ABSTRACT           A self supporting tunnel is formed directly above a recovery zone in a subterranean ore deposit, such as oil shale.  A room is formed having horizontal dimensions corresponding approximately to the horizontal cross section of the recovery zone.  A vertical raise is formed in the middle of the recovery zone between the tunnel and the room. The ore in the recovery zone is fragmented in sequential steps to fill the raise and the room.  The top of the recovery zone is also filled with fragmented ore to support the overburden, and is spaced downwardly from the tunnel to form therebetween a pillar of unfragmented ore.  The room is the base of operations in preparation for fragmentation. A processing fluid is introduced into the recovery zone from the tunnel to release constituents from the ore and to transport the constituents to the bottom of the recovery zone. The constituents are removed from the bottom of the recovery zone.  In working a large deposit, a plurality of recovery zones are arranged in row and columns, the tunnel is part of a network communicating with the tops of the recovery zones and the room is part of a grid of rooms from which the recovery zones are prepared.

Abstract: TIMING RECOVERY CIRCUIT    FOR DIGITAL DATA     Abstract of the Disclosure A timing recovery circuit receives a timing component signal and generates a signal having a frequency varying in response to a control signal.  In response to a difference between the phase of the variable frequency signal and the phase of the timing component signal, the circuit produces a control component.  In response to cycle slips between the variable frequency signal and the timing component signal, the circuit produces a series of pulses having a polarity related to the sense of the cycle slips and having a pulse rate directly related to the rate of the cycle slips except when amplitude of the timing component signal falls below a predetermined value whereupon no pulses are produced.  The control component and the series of pulses are combined into the control signal that adjusts the frequency of the generated signal into synchronization with the timing component signal.

Abstract: ABSTRACT              A  process for preventing deposits when venting steam containing entrained polymer from high pressure reactors used for preparing nylon from dicarboxylic acid and diamine.  The hot steam generated during condensation polymerization of the reactants is vented through a pressure-control valve at a rate which maintains a desired pressure in the rector.  De-posit of polymer in the valve or vent pipe after release of pressure is prevented by injecting water into the low pressure side of the valve or into the subsequent vent pipe.  At least sufficient water is used to saturate the vented steam and to wet the walls of the vent pipe.
