Abstract: The circuit in CMOS technology allows high speed driving of optical sources, in particular laser diodes, operating efficiently at speeds that meet the requirements imposed by optical fibre communication on systems and avoiding interference between driving currents and biasing current in the optical source. The circuit comprises a bias current generator, a modulation current generator and a cascade of CMOS inverterstages that supplies a driving voltage to the modulation current generator and receives digital signals at its input. It is possible to independently adjust the bias current, so as to allow driving sources with different threshold currents, and to adjust the modulation current.

Title: Human n-methyl-d-aspartate receptor subunits, nucleic acids encoding same and uses therefor
Inventor: DAGGETT LORRIE P
IPC: G01N33/50
Filed: 1994-04-20
Granted: 2009-10-06
Abstract: In accordance with the present invention, there are provided nucleic acids encoding human NMDA receptor protein subunits and the proteins encoded thereby. The NMDA receptor subunits of the invention comprise components of NMDA receptors that have cation--selective channels and bind glutamate and NMDA. In one aspect of the invention, the nucleic acids encode NMDAR1 and NMDAR2 subunits of human NMDA receptors. In a preferred embodiment, the invention nucleic acids encode NMDAR1, NMDAR2A, NMDAR2B, NMDAR2C and NMDAR2D subunits of human NMDA receptors. In addition to being useful for the production of NMDA receptor proteins subunit, these nucleic acids are also useful as probes, thus enabling those skilled in the art, without undue experimentation, to identify and isolate related human receptor subunits. Functional glutamate receptors can be assembled, in accordance with the present invention, from a plurality of one type of NMDA receptor subunit protein (homomeric) or from a mixture of two or more types of subunit proteins (heteromeric). In addition to disclosing novel NMDA receptor protein subunits, the present invention also comprises methods for using such receptor subunits to identify and characterize compounds which affect the function of such receptors, e.g., agonists, antagonists, and modulators of glutamate receptor function. The invention also comprises methods for determining whether unknown protein(s) are functional as NMDA receptor subunits.

Abstract: A sampling cylinder 3 is attached to a process piping 2 through which a slurry flows. A front piston 9 and a rear piston 10 which slide within the sampling cylinder 3 are driven via a driving rod 12 by a fluid pressure cylinder 11. These two pistons 9,10 are allowed to slide to collect the slurry into a sampling space 30 defined between the pistons 9,10. The front piston 9 is brought closer to the rear piston 10 to reduce the volume of the sampling space 30. Thus, only the filtrate in the slurry is fed through a filter 5 into a filtrate collecting tank 6, where pH etc. of the filtrate is measured by a sensor 8. Subsequently, the front piston 9 is brought apart from the rear piston 10 to increase the volume of the sampling space 30. Thus, the filtrate is returned into the sampling space 30 back-washing the filter 5. Then, the slurry in the sampling space 30 is returned to the process piping 2.

Title: Filter condition sensor and indicator
Inventor: HENDRIX GEORGE E
IPC: A47L9/28
Filed: 1996-04-22
Granted: 2000-07-04
Abstract: A filter condition sensor and indicator is disclosed. A filter condition sensor and indicator that responds to the presence of a predetermined collection of material in a filter operatively positioned in an output air flow path. A small by-pass air flow path is connected to the output air flow path and is separate from the filter. A heated thermistor is positioned in the by-pass air flow path. Electrically connected in series with the heated thermistor is an indicator light that illuminates when the resistance in the circuit is decreased due to predetermined cooling of the heated thermistor. In this way, a predetermined collection of material in the filter increases the flow of air in the small by-pass air flow path for cooling the heated thermistor and for lowering the resistance in the circuit to illuminate the indicator light. Even in those instances where a multi-speed fan is located in the output air flow path, the present invention overcomes changing fan speeds and changing air velocity by coupling the thermistor in a circuit which changes the voltage and current through the thermistor depending on the fan setting.

IPC: H03M5/14

Granted: 2000-10-17
Abstract: Method and apparatus for encoding digital information to be recorded on a magnetic medium is disclosed.  The invention provides for receiving a sequence of (2mn + d) user bits, mapping the sequence of user bits to 2m dc-free codewords, and recording the 2m dc-free codewords on a magnetic medium.  A modulation coder, which includes a memory containing multiple non-intersecting subconstellations of dc-free codewords, performs the mapping in a non-equiprobable manner such that a particular codeword from a larger subconstellation is more likely to be used than a particular codeword from a smaller constellation.  Less desirable codewords, such as those containing relatively long strings of bits having the same value, are assigned to the smaller subconstellations, thereby lessening the likelihood of loss of timing and gain parameters in the system, as well as maximizing the transmission rate and efficient use of the set of possible dc-free sequences of a given length.

Title: Coupling for anchor bars
Inventor: PAPOUSEK HERBERT JUN
IPC: E21B17/042
Filed: 1994-11-25
Granted: 2005-01-11
Abstract: For coupling anchor bars (2) of injection anchors, the anchor bars are screwed with their outer threads (4) into a coupling sleeve (1) provided with a corresponding inner thread (5). One of the two anchor bars (2) screwed into the coupling sleeve (1) has a chamfered surface (8) formed by an end chamfer and lies on a break (6) of the inner thread (5) of the coupling sleeve (1). The second anchor bar (2) is screwed into the coupling sleeve (1) until its end face (9) lies completely on the end face (9) of the other anchor bar (2). This ensures an advantageous transmission of forces during drilling and prevents the coupling sleeve (1) from turning during drilling.

Abstract: A settable thixotropic material comprises a thixotrope and a settable substance, the material being capable of gelling reversibly in a gelling time of less than 60 seconds. The thixotrope conveniently comprises a fine grained clay, especially smectite clays, e.g. hectorites. It is preferred to use synthetic smectite type clay colloids, and good resul ts have been obtained with the synthetic clay known as Laponite RDS. The settable material conveniently comprises cement, particularly Portland cement. The thixotropic material finds use generally in oilwell applications, e.g. to plug lost circulation zones, to repair damaged or corroded casing, as grouts, and to limit annular gas migration. The material also finds particular application in techniques for completion of horizontal wells completed with slotted or pre-drilled liners, as described in International Application WO-95/00739.
