Inventor: LIBOFF ABRAHAM R
IPC: A61N1/30
Filed: 1989-11-22
Granted: 2001-04-17
Abstract: An improved apparatus and method for regulating transmembrane ion movement through a biochemical membrane. The apparatus includes a magnetic field generator and a magnetic field detector for producing a controlled, fluctuating, directionally oriented magnetic field parallel to a predetermined axis projecting through the membrane. The field detector samples the magnetic flux density along the predetermined access and provides a signal to a microprocessor which determines the average value of the flux density. This ratio is maintained by adjusting the frequency of the fluctuating magnetic field and/or by adjusting the intensity of the applied magnetic field as the composite magnetic flux density changes in response to changes in the local magnetic field to which the target membrane is subjected. By maintaining these precise predetermined ratios of frequency to average magnetic flux density, ion transport is controlled.

Title: Agricultural depth control system including cross plumbed series cylinders
Inventor: BARBER DENNIS RAY
IPC: A01B63/22
Filed: 1990-04-25
Granted: 1996-04-09
Abstract: A hydraulic control system is provided which includes a pair of transversely spaced rockshaft cylinders which are plumbed in parallel and connected to opposite ends of a rockshaft on the central portion or main frame of a wide implement such as a field cultivator or chisel plow.  The left-hand rockshaft cylinder is connected in series with a right-hand outer cylinder located near the right end of the implement.  The right-hand rockshaft cylinder is connected in series with a left-hand outer cylinder on the opposite side of the implement.  When a ground condition exists which causes, for example, the left side of the implement to dig more deeply and the left-hand wing cylinder to retract, the right-hand rockshaft cylinder will also be caused to retract so the right side of the implement tends to dig in more deeply.  At the same time because of the parallel connection of the rockshaft cylinders, the left-hand rockshaft cylinder will be forced to extend to reduce the depth of penetration of the left side of the implement which offsets the tendency of the left side to dig in and provides a more uniform average working depth across the width of the implement.

Title: Serving constant bit rate traffic in a broadband data switch
Inventor: PUNJ VIKRAM
IPC: H04L12/56
Filed: 1991-05-30
Granted: 1994-02-15
Abstract: Abstract This invention relates to a method and apparatus for transmitting constant and variable bit rate traffic in a broadband ISDN switch. Data from constant bit rate sources such as television cameras is entered into a group of queues. Each member of the group for queuing data of a different band of bit rates. Data is transmitted from these queues with highest priority from the queue storing data of the highest band of bit rates. If the longest enqueued entity of data in one of the other queues has been enqueued for more than a prespecified period, its priority is increased. Analytic studies have shown that use of three queues for constant bit rate traffic and a fourth queue for variable bit rate traffic allows a high occupancy in the output channels to be maintained with a negligible number of data entities excessively delayed.
