Title: Multi-station dangerous condition alarm system incorporating alarm and chirp origination feature
Inventor: O'DONNELL THOMAS J
IPC: G08B27/00
Filed: 1998-07-24
Abstract: In a dangerous conditions sensing alarm system which includes a plurality of interconnected dangerous condition sensing units (Unit A, Unit B 70, Unit C  71, Unit D 72, Unit E 73), such as smoke detectors, of the general type in which each unit responds to an apparently sensed dangerous condition by issuing an audible alarm and also by transmitting, from an input/output terminal (20 - I/O), a signal to the other units (received as an external alarm signal at corresponding input/output terminals of the other units) so that an alarm condition sensed by any one of the units results in alarms being sounded by all the units, a unit initiating an alarm (which may be false) is marked by an alarm origination circuit. The alarm origination circuit includes a visual indicator such as an LED (61) and a latch device such as an SCR 51 connected in-circuit such that, when the SCR is turned "on", the LED is activated and remains lit until the SCR is turned "off". The SCR is turned "on" by a signal developed from the audio frequency drive to the unit annunciator (22) unless this action has been earlier inhibited by an electronic switch (52) which, just before the local alarm is sounded, places a virtual ground on the SCR gate (75). The electronic switch is activated by an external alarm signal more quickly than the local unit's audio frequency drive is established. Thus, an external alarm signal will not cause the LED to light at the local unit.

Title: 1 1/2 piston force pump
Inventor: SWEENEY GERALD T
IPC: F04B9/107
Filed: 2000-02-24
Abstract: A deep well fluid pump which enables the pumping of fluid with much less energy which includes a power column of fluid of sufficient volume, which communicates to the under side of the lifting piston for the column of fluid to be lifted, but is isolated from said fluid to be lifted, to balance the head force of the column of fluid to be lifted, a pump means to increase the head force on the power column of fluid a sufficient amount to overcome the seal friction and pre-load spring down force of the lifting piston, so that it raises the lifting piston and thus discharges a volume of lifted fluid in a surface reservoir, and when the increased force on the power column is relieved, the pre-load spring forces the lifting piston down to reload.

Title: Method of multistage gas phase polymerization, apparatus therefor and device for reducing entrainment of subcomponents in polymer powder in apparatus for multistage gas phase polymerization
Inventor: KIKUCHI YOSHIAKI
IPC: C08F10/00
Filed: 2000-03-30
Abstract: A method of multistage gas phase polymerization, comprising performing polymerization of a feed gas mixture at least containing ethylene gas, an .alpha.-olefin gas and hydrogen gas in an upstream arranged fluid bed reactor to thereby obtain polymer powder, taking up the polymer powder therefrom and performing further polymerization of the polymer powder in a downstream arranged fluid bed reactor, the downstream arranged fluid bed reactor continuously connected to the upstream arranged fluid bed reactor so that the polymer powder taken up from the upstream arranged fluid bed reactor is introduced into the downstream arranged fluid bed reactor, which method comprises the steps of: taking up polymer powder from an upstream arranged fluid bed reactor, treating the taken up polymer powder so as to lower a content of .alpha.-olefin gas and hydrogen gas therein, and introducing the treated polymer powder into a downstream arranged fluid bed reactor. In this multistage gas phase polymerization method, when the polymer powder taken up from the upstream fluid bed reactor is carried while being entrained by a feed gas for the downstream fluid bed reactor so that the polymer powder is introduced into the downstream fluid bed reactor, hydrogen gas and comonomers which inhibit the polymerization reaction in the downstream fluid bed reactor and which render regulation of desired polymer properties difficult are removed from the polymer powder.

Inventor: TSURUMI TAKAFUMI
IPC: B60L3/00
Filed: 2000-05-04
Abstract: In a propulsion system for hybrid vehicles, etc., the present invention provides a failure detection system that detects the occurrence of failure that obstructs a phase current supplied to an electric motor for propulsion. The direct current of the battery 3 is converted to three-phase alternating current by an inverter 200 and supplied to the electric motor M. The controller 100 drive controls the inverter 200 so that the output torque of the electric motor M attains a target torque. Each of the phase currents supplied to the electric motor M are detected by the current sensor S10, and provided to a comparator 104. The comparator 104 compares the value of each of the detected phase currents and the current limit value 103S calculated by the current limit value calculation circuit 103, and outputs a signal 104S showing that a current phase has abnormally risen. This signal 104S is counted by the counter 105, and the occurrence of failure is identified based on this count value.

Abstract: A method and apparatus for performing chemical and biochemical reactions in solution using in situ generated photo-products as reagent or co-reagent. Specifically, the method and apparatus have applications in parallel synthesis of molecular sequence arrays on solid surfaces. There is provided an apparatus for performing light controlled reactions. One of the applications of the apparatus is to control reactions on a solid surface containing a plurality of isolated reaction sites, such as wells (the reactor). Light patterns for effecting the reactions are generated using a computer and a digital optical projector (the optical module). Patterned light is projected onto specific sites on the reactor, where light controlled reactions occur. A preferred application provides the in situ generation of chemical/biochemical reagents that are used in the subsequent chemical and biochemical reactions in certain selected sites among the many possible sites present. One aspect of the claimed invention is to change solution pH by photo-generation of acid or bases in a controlled fashion. Another preferred application is the parallel synthesis of biopolymers, such as oligonucleotides and peptides, wherein the method and apparatus are used for selective de protection or coupling reactions.
