Title: Electromechanically actuated intake or exhaust valve for i.c. engine
Inventor: STEPHAN CRAIG HAMMANN
IPC: F01L9/20
Filed: 1997-11-12
Abstract: An electromechanically actuated valve (12) for use as an intake or exhaust valve in an internal combustion engine. The valve (12) is actuated by a electromechanical actuator assembly (18) which includes a first electromagnet (22), second electromagnet (30) and third electromagnet (32). A first disk (38) is slidably mounted to the valve (12) in a gap between the first and second electromagnets with first and second stop members (39, 41) limiting its travel along the valve stem (15). A third spring (52) biases the first disk (38) toward the first stop (39). The gap between the first and second stops (39, 41) is large enough to allow for manufacturing tolerances and temperature changes, with a third spring (52) acting to create soft landings. A second disk (44) is slidably mounted to the valve (12) above the third electromagnet (32) with a third stop member (40) limiting its travel toward the first disk (38). With the valve (12) being in a closed position, the gap between the first disk (38) and the first electromagnet (22) is greater than the gap between the second disk (44) and third electromagnet (32), allowing for multiple valve lifts. A first spring (48), mounted between the cylinder head (14) and first disk (38), and a second spring (50), mounted between the second disk (44) and an actuator housing (20), create an oscillatory system which drives the valve movement during engine operation, thus reducing power requirements to actuate the valves.

Title: Optical phase modulation
Inventor: PECHSTEDT RALF-DIETER
IPC: G02F1/01
Filed: 1998-05-19
Abstract: The optical system comprises two optical paths P 1 , P 2 , and an arrangement for changing the length of the two paths including two phase modulators M 1 , M 2  one coupled to each of the paths. A driving system applies power to the phase modulators to drive them in the same direction and to change the amount of power applied to the phase modulators in opposite directions so as to change the length of each optical path in a different direction. As a result, the relationship between the changes in the amount of power applied to the modulators and the resulting changes in the phase of light beams passing through the device becomes substantially linear.

Title: Pressure balanced solenoid valve
Inventor: KEEGAN COLM MICHAEL PATRICK
IPC: F16K31/06
Filed: 1998-06-02
Abstract: A valve comprises a valve member 16 movable between a closed position in which it seals against a first seat 28 to prevent communication between an inlet and an outlet, and an open position in which it is clear of the seat to permit communication between the inlet and the outlet. A fluid passageway 64 allows pressures on each side of the valve member to equalise and so balance the forces acting on the valve member. The valve member seals against a further seat 58 in the closed position to prevent communication between the inlet and outlet via the passageway. The valve member moves clear of the further seat in the open position.

IPC: G06G7/20
Filed: 1998-09-25
Abstract: An OTA having a completely linear transconductance characteristic or a squarer having an accurate square-law characteristic is provided, which is comprised of first and second differential circuits. The first differential circuit has a first differential pair of first and second MOSFETs whose sources are coupled together and a third MOSFET serving as a bypass transistor for the first differential pair. The first differential pair is driven by a first constant tail current. The second MOSFET is driven by a first constant driving current. The second differential circuit has a second differential pair of fourth and fifth MOSFETs whose sources are coupled together and a sixth MOSFET serving as a bypass transistor for the second differential pair. The second differential pair is driven by a second constant tail current. The fifth MOSFET is driven by a second constant driving current. A differential input voltage is applied across gates of the first and second MOSFETs and across gates of the fifth and fourth MOSFETs. When a difference or sum of drain currents of the first and fourth MOSFETs is used as an output, an OTA or squarer is realized. If each of the MOSFETs in the first and second differential circuits is replaced with a bipolar transistor, a hyperbolic sine or hyperbolic cosine circuit is realized. Figures 6, 10A and 10B show a single differential circuit squarer, a hyperbolic cosine and a hyperbolic sine circuit respectively.

Date Jun. 8, 1995A digitized real voice signal is converted via complex filtering into a complex signal that is subjected to sampling rate reduction, the bandwidth of the respective complex filter corresponding to the sampling rate. The complex signal is phase-modulated by means of a code signal generated by a random-number generator and additively combined with a pilot signal (likewise phase-modulated in a random distribution) to form an encrypted useful signal for transmission. The useful signal is sequentially transmitted together with a preamble for synchronization and signal equalization at the receiver end. At the receiver end, clock synchronization is forced for a phase-modulated pilot signal produced at the receiver end and equalizer coefficients for an equalizer at the receiver end are calculated from the digitized received signal after complex filtering and corresponding sampling rate reduction, during a preamble recognition phase, at which point the phase of the useful signal decryption is initialized. The encrypted, transmitted signal is separated from its phase-modulated pilot signal, which is superimposed at the transmitter end, by linking to the synchronized pilot signal, which is produced at the receiver end, and the phase-modulated, encrypted digital speech signal thus obtained is subsequently decomposed by the code signal produced at the receiving end and clockcontrolled by the preamble.

Title: Process for determination of triiodothyronine
IPC: G01N33/53
Filed: 1973-04-25
Abstract: A radioimmunoassay method for the determination of triiodothyronine in human and animal fluids and tissues, particularly in serum. The method involves the separation of triiodothyronine from its binding proteins using a dextran gel column followed by competitive binding between the freed triiodothyronine and radioactive labeled triiodothyronine which remain bound to the gel column for triiodothyronine-specific anti-serum. Bound and free labeled triiodothyronine are separated by washing the column and their ratio is determined based on the amount of radioactivity remaining in the column to that originally added thereto.

Filed: 1978-01-31
Abstract: PURPOSE:To make possible stable automatic focusing without using any pinhole and make adjustment of optical system easy by so constituting the device as to adjust its objective lens in its optical axis direction by the use of a semiconductor light source. CONSTITUTION:The laser light 2 out from a semiconductor light source 14 is focused on the surface of a video disc 4 by an objective lens 3 and the reflected light thereof goes backward in the condensing optical path and enters the light emitting part 15 of the light source 14. The change in the output of the light source 14 by this is detected with a photo detector 8 and is signal processed 16, whereby video reproduction is accomplished. The output of the photo detector 8 inverts in its phase when the surface of the disc 4 deviates from the focus position by the lens 3. This phase is then phase-detected 12 with the output of an oscillator 11 and is applied via mixer circuit 17 to an actuator 13, which in turn adjusts the mean position of the lens 3 in its optical axis direction. As a result, the focus may be automatically matched to the surface of the disc 4.

Title: Condenser electrostatic capacity measurement device

IPC: G01R27/26
Filed: 1980-01-31
Abstract: PURPOSE:To make possible measurement of DC electrostatic capacity in a fixed period regardless of the electrostatic capacity of a condenser to be measured by constituting a power supply whose voltage increases at a fixed ratio against time. CONSTITUTION:A fixed current circuit is constituted with FETQ1 and a resistance R. If a switch S is opened, a condenser C1 is charged by means of a DC power supply E and an interterminal voltage climbs up at a fixed ratio with time. This soaring voltage is converted in terms of impedance under the emitter follower action of Q2, so that a power supply 1 whose voltage increases at a fixed ratio against time is obtained. This output current is applied to a condenser C2 to be measured through the intermediary of a DC ammeter A. Thus the electrostatic value of the C2 is obtained based on the reading of the ammeter A.
