Title: Xanthine Derivatives as Adenosine A1 Receptor Antagonists
Inventor: HITCHCOCK JANICE M
IPC: A61P25/28
Filed: 1994-01-27
Abstract: The present invention relates to a group of compounds which are xanthine derivatives and which act selectively at adenosine A1 receptors. Adenosine antagonists acting at the Al receptor depolarize postsynaptic neurons and presynaptically enhance the release of a number of neurotransmitters including acetylcholine, glutamate, serotonin, and norepinephrine. This action has potential for treating cognitive deficits such as those associated with Alzheimer's disease, as these transmitters have been implicated in learning and memory, and each of these transmitters is reduced in Alzheimer's disease. Some of the A1 antagonist compounds described in the present invention increased the activity of hippocampal neurons in a long-term potentiation in vitro learning model, and antagonized a scopolamine deficit in a water maze in vivo learning model. Thus, these compounds have potential for cognition-enhancing effects.

Filed: 1995-11-07
Abstract: The noise from the effects of currents through distributed capacitances between electrical circuitry on an integrated circuit chip and the chip substrate is minimized, especially for analog circuitry mixed on the chip with digital circuitry.  The invention separates a plurality of bits in each digital word into a plurality (e.g. 2) of segments.  A first register off the chip latches the first bits in each word with a first clock signal.  A second register off the chip latches the second bits in each word with a second clock signal delayed from the first clock signal.  The first register bits are latched on the chip with the first clock signal by a third register.  The delayed second register bits are latched on the chip by a fourth register with the second clock signal or with a delayed first clock signal having the same delay as the second clock signal.  Substrate ties for the third and fourth registers may be connected to at least one, preferably a plurality, of bonding pads on the chip.  The bits from the third and fourth registers may be combined on the chip into a single word. Alternatively, the bits from the third register may be delayed on the chip by the delay of the second clock signal and combined with the bits from the fourth register.  In another alternative, the combined signals may be re-registered on the chip in a fifth register in accordance with a clock signal having the delay of the second clock signal.

Title: Method and apparatus for separating a heavier phase from a lighter phase in a material flow by centrifugal force
Inventor: BIELEFELDT ERNST AUGUST
IPC: B04C7/00
Filed: 1996-01-22
Abstract: Phases of different densities are separated from each other in a vortex separator chamber.  A primary flow to be cleaned drives a secondary vortex flow in the chamber.   The primary flow is introduced into the chamber centrally between the chamber ends through at least one flow inlet channel or bed having an axial length shorter than an axial chamber length and a radial inlet depth such that the primary flow is adapted to the secondary vortex flow.  For this purpose the primary flow is fanned-out so that it smoothly merges into the secondary vortex flow close to the inner surface of the chamber wall to avoid turbulent flows and thus losses of the primary flow energy are reduced.  Cleaned gas is sucked out through immersion pipes reaching centrally into the chamber from opposite ends.  Heavier particles are removed by centrifugal force and discharged through gaps in the end walls of the chamber and/or through at least one peeling slot in the axial cylindrical or spirally shaped chamber wall.

Title: Proportional chemical feeding system
Inventor: SCHRANDT HENRY M
IPC: F04B49/06
Filed: 1996-04-11
Abstract: A treatment system is described having a controllable pump with an automatic calibration and measuring system. Pumped volume can be determined during each cycle using a fluid flow measuring device and a controller. The fluid flow measuring device has a totalizer counter, and batch measurement capability. For each batch, the fluid flow measuring device sends a ready signal to the controller. The controller sends a start signal to initialize the totalizer counter and tells the totalizer to start flow measurement. When the totalizer value equals the batch value, a batch complete signal is sent, defining a predetermined volume by which the controller measures and automatically calibrates the system. The controller determines the number of cycles of the pump required to pump the predetermined volume, and determines deviation from a pre-established number. The pump responds to the detected deviation.
