Title: Amplifier arrangement
Inventor: LAMBRECHTSE CORNELIS W
IPC: H03K5/153

Abstract: ABSTRACT OF THE DISCLOSURE Write and/or read amplifier, which comprises first and second in-verting amplifiers equipped with insulated-gate field-effect transistors connected in cascade.  The first inverting amplifier is shunted by a first switching unit and the input of the second inverting amplifier is connected to a point of constant voltage via a third switching unit, which third switching unit is controlled by the output voltage of the second inverting amplifier.  The read process is performed during a two-phase cycle.  During the first phase the first switching unit is in the conducting state, so that negative feedback is obtained, which is discontinued at the end of the first phase.  A requirement for this is that the output voltage of the second in-verting amplifier keeps the third switching unit in the non-conducting state during the first phase.  During the second phase an input signal is applied to the amplifier, so that depending on the input signal the output signal of the second inverting amplifier drives the third switching unit in the con-ducting or non-conducting state.  In the case in which said third switching unit becomes conductive, the second inverting amplifier is driven into con-duction.  A second switching unit is then made conductive, which unit con-nects the input of the amplifier arrangement to a point of constant voltage for restoring the input signal in this logic condition.  In the logic condit-ion for which the third switching unit remains non-conducting, no signal restoration is effected.

Abstract: ABSTRACT OF THE DISCLOSURE Three-phase power equipment while still connected to the three-phase line has the insulation qualities of its various phases tested.  All ground connections of said equipment except one are disconnected and that one is reconnected through ground current sensing means.  Coupling units which may be capacitors are respectively connected between each of the three phases of the power line to which the power equipment is connected and ground.  Each coupler unit is a reference phase current sensing means.  Adjustable phase and magnitude adjustor means are used to couple the respective phase current sensing means to a summing means so that they are adding.  The ground cur-rent sensing means is similarly coupled to the same summing means but opposed to phase current effects.  A null detector coupled to the summing unit de-tects when balance occurs.  Each of the phases is checked in sequence using fixed predetermined settings of the phase and magnitude adjusting means for the other two phases and separately and sequentially varying the settings of capacitance and dissipation factor for the phase under test until nulling occurs.  Deviation in the settings of the adjustable phase and magnitude adjustor means from previous settings are considered in determining whether changes suggest deterioration of insulation and in which phase such deterior-ation may be occurring.

Abstract: REGENERATOR FOR AN OPTICAL TRANSMISSION SYSTEM     Abstract of the Disclosure An optical pulse stream regenerator includes an optical receiver, a decision and timing circuit, and an optical transmitter.  In response to an incident optical data pulse stream, a variable gain receiver section produces an electrical data pulse steam representing the incident optical data pulse stream.  The receiver section is stabilized by having different variable gain devices respond to separate ranges of an automatic gain control signal.  In response to the receiver section electrical data pulse stream, a phase-lock frequency-lock circuit in the timing circuit recovers a clock pulse stream that is synchronized with the incident optical data pulse stream, and the decision circuit regenerates an electrical data pulse stream representing the incident optical data pulse steam. In the transmitter section, an injection laser is controlled by the regenerated electrical data pulse stream and by a prebias signal that is established in response to the difference between a signal representing the optical output power of the laser and a signal representing the regenerated electrical data pulse stream.  The injection laser regenerates an output optical data pulse steam representing the incident optical data pulse stream.      - i -

Abstract: CONVERGENT LIGHT ILLUMINATED FLOW CELL      FOR LIQUID CHROMATOGRAPHY                   Abstract of the Disclosure Single and dual beam flow cells for liquid chromato-graphy that provide good detectability and linear response with small sample volumes.  A cylindrical window surrounds the  sample flow path to permit focusing convergent light rays through the center of the flow path and along optical paths of equal length through the cell.  Optical stops limit the light passing through the cell to convergent rays incident to the window surface.  A wide acceptance angle for the rays results in high light transmission and averages variations in light output along the light source.  A dual beam flow cell utilizes a common exit for the sample and reference liquids.  The flow cells are economically constructed for direct coupling to a chromatographic column by using a standard compression fitting union and can be used in a single wavelength or discrete wavelength detector, or in a spectrophotometer.

Abstract: SELF-LOCKING KEY CONTROLLED DOOR LOCK                      Abstract A flush-mountable, key-controlled, handle-operated door lock is provided with an automatic self-locking linkage for permitting the handle to move once, but only once, out of a nested position after a key control has been operated to "cock" the linkage.  Once the linkage has been cocked, the handle can be moved one time out of and returned to its nested position, whereafter the linkage operates to retain the handle in its nested position until the key control is again operated to cock the linkage.  The automatic latching linkage includes a housing assembly, a pair of cams, and a pair of springs.  A feature of the automatic latching linkage is that its several components can be assembled easily on an existing, in-service lock to provide the existing lock with a one-trip automatic locking capability.  The latching linkage components are assembled by installing the components one at a time in an essentially stacked arrangement, one atop the other.  The simple assembly steps required can be carried out even where accessibility to the rearward face of an in-service lock is quite limited.
