Title: Automatic gain control for a receiver in which the need for a digital to analog converter at the output of a feedback loop is obviated by using an integrator
Inventor: HULBERT ANTHONY PETER
IPC: H03G3/30
Filed: 1996-07-20
Abstract: An automatic gain control system for adjusting the gain of amplifiers of a radio signal receiver in accordance with an amplitude of discrete time signal samples of a received signal, the gain control system comprising an amplitude measuring unit for measuring the amplitude of the discrete time signal samples, a comparator which operates to compare the amplitude with a predetermined threshold and to generate a gain control signal, and an integrator being connected to the comparator which operates to integrate the gain control signal and to feed the integrated gain control signal to a control input of the amplifiers for amplifying the received signal, thereby providing a reduced complexity gain control system, wherein measurement of the received signal and comparison with a desired amplitude is performed in a digital domain of the receiver, without a need for a digital to analogue converter.

Title: Minimizing interzonal migration in boreholes
Inventor: BOYD JOHN WESLEY
IPC: E21B33/134
Filed: 1998-04-14
Abstract: A process and a material is for use in sealing casing lining in a borehole. The process includes the placement of a bitumen sealant material in a position between the casing tube and the wall of the borehole to be maintained in this annulus by means of a retaining devise such as an external casing packer or with the placement of a retainer made of cement grout and situated at the lower end of the casing tube. The bitumen sealant material prevents the passage of fluids vertically through the borehole. The sealant material remains viscous over time and can flow to fill voids which may occur in the rock formations adjacent to the borehole, or in the steel casing of the casing tube. To improve the sealing capabilities of the bitumen material a measured amount of fine grain weight material can be added to the bitumen to increase the density of the sealant material and thereby increase the hydrostatic pressure that the column of bitumen sealant will exert on the bottom and the walls of the borehole. The material may also be used in the bottom of a borehole to shut it off. Several methods of inserting the bitumen are disclosed.

Title: Roller blind with retraction limiter, extension limiter, skew adjuster and modular bottom rail
Inventor: COLSON WENDELL B
IPC: E06B9/32
Filed: 1999-06-22
Abstract: A control and suspension system for a retractable blind mounted on a rotating element includes an apparatus for mechanically limiting over-retractions of the covering (see figures 4 and 5B) and another apparatus for mechanically limiting over-extensions of the covering (see especially figures 5A and 23). The apparatus for limiting over-retraction includes a threaded shaft 72 and an internal wheel 152 threaded on the threaded shaft 72. The wheel 152 is prevented from rotation relative to roller 36 by means of a longitudinal tongue 114 and groove 160. As the blind is rolled up on to roller 36 the wheel 152 moves along the thread 72 until an intercepting ledge 166 comprising part of the wheel 152 contacts a stopping ledge 150 comprising part of the threaded shaft 72, thus preventing the roller 36 from being further rotated. The apparatus for limiting over-extension includes a second wheel 86 having a stop 92 pivotally mounted thereto. When the blind is fully lowered and its covering material is fully extended, the stop 92 rotates away from the wheel 86 under gravity and prevents further rotation of the roller 36 by contacting a substantially annular channel wall in an end cap 66. A skew adjustment means is also provided (see figures 3B and 5A). By turning a screw 76 within a screwthread 84 the end cap 66 can be raised and lowered to ensure that the roller 36 is horizontal. Also provided is a bottom rail that attaches to the bottom of the blind covering by trapping a portion of the covering material between a compression plate and a bottom plate (see especially figures 9-16).
