Granted: 1995-09-21
Abstract: A receiver comprising, arranged in this order, an input section, an FM demodulator, to which a frequency-modulated input signal is applied, and an LF section, which FM demodulator comprises a pulse shaper and a low-pass filter the pulse shaper comprising a series arrangement of at least a load and a capacitance, the base-emitter junction of a transistor being arranged across the capacitance, and further comprising a switching device for charging and discharging the capacitance. The pulse shaper generates a low-noise pulse in that charging of a capacitance is started upon an edge of the input signal. The capacitance voltage is measured by a single transistor and when the transistor is turned on the charging current of the capacitance is diverted via the transistor, so that the capacitance voltage is limited. The capacitance is discharged upon a second edge, after which the cycle is repeated. The output signal of the pulse shaper is a signal which varies with the current through the capacitance.

Title: Two-part coupling structure
Inventor: DOUGLAS K STRICKLIN
IPC: F16L37/42
Filed: 1995-05-09
Granted: 1998-06-21
Abstract: A two-part coupling structure (20,22) includes a male coupling part (22) and a female coupling part (20) which are mutually engageable to open fluid communication between a fluid-storage vessel (18) and a conduit (16). The coupling parts are disengageable from one another to discontinue fluid communication between the vessel and the conduit, and also to close communication between ambient and each of the vessel and conduit. The retention volume of fluid which is trapped between the connected male and female coupling parts and which is exposed to or lost to ambient when the coupling parts are disconnected is very small. Because of particular structural features, the coupling parts will function reliably even with fluid having chunks or particulates of non-fluid material therein.
