Abstract: ABSTRACT OF THE DISCLOSURE          An incandescent lamp, which emits infra-red radiation, comprises a tubular quartz envelope, within which a tungsten filament is supported.   To reflect radiation, which is emitted in a downward direction from the filament, back in an upward direction to an item to be heated, a substantially pure aluminium oxide coating is bonded in a substantially permanent manner to the surface of the envelope.   The coating extends substantially along the length of the lamp and around approximately half of the cross-sectional circumference thereof.   The coating is applied to the envelope by a spray gun technique, wherein finely divided aluminium powder is blown through an oxygenated flame, which is directed towards an area of the envelope to be coated.

Abstract: ABSTRACT      A pool entrance and supporting structure which will both provide an entrance exit from an above-ground pool and will also provide   support for both a skimmer and a return.  The pool entrance and supporting structure (40) includes an entrance structure (42).  The entrance structure includes a pair of spaced apart ladders (44, 46) and a platform (48) which extends between upper end portions of the ladders.  The pool entrance and supporting structure support means (52).      By employing the novel pool entrance and supporting structure of this invention improved  circulation is achieved within the pool reducing the need for vacuuming, chemicals, and filtering.  In addition, the problems encountered with through wall skimmers and returns will be eliminated.  Additionally, it will be easier to winterize the pool as the skimmer and return can readily be removed from the pool and stored in an area which will not subject the various components to freezing.

Abstract: ABSTRACT OF THE DISCLOSURE      An electronic pressing iron having a soleplate and a housing connected to the soleplate is disclosed herein.  An electric resistance heating element is mounted in the soleplate for receipt of an alternating current from a suitable source.  A temperature control thermostat is connected in series with the electric heating element and is mounted in good heat conduction relationship with the soleplate to control the temperature thereof.  A motion and attitude sensing switch is mounted in a handle of the housing and provides a motion signal to a programmable timer also mounted in the handle.  A thermal relay mounted in the handle is connected to the programmable timer to receive a time out signal therefrom.  When the electronic pressing iron is switched on and is stationary with its soleplate oriented horizontally, for a period of thirty seconds, the programmable timer signals the thermal relay which interrupts the electric current flowing through the heating element.  When the electronic pressing iron is resting on its heel rest and is not moved for a period of sixteen minutes, the programmable timer also signals the thermal relay to interrupt electric current flowing through the electric heating element.

Accordingly, the pigment particles (9, 16, 25) totally cover transparent electrodes (3, 4, 13, 14, 23, 24, 33), which condition can be changed by applying the appropriate electric field to the opposite electrode (3, 4, 13, 14, 23, 24, 33). By this structure, various alphanumeric displays can be constructed.

Abstract: INTERFERENCE CANCELER WITH DIFFERENCE BEAM            Abstract Undesired signals from interfering satellites are separated from desired signals from a target satellite by using a sum beam and a difference beam as in a monopulse radar.  Both desired and undesired signals are received by an antenna and separated by different mode couplers from a waveguide.  The fundamental mode of the waveguide provides the desired signals along with components from the interfering signals.  Both desired and undesired signals are picked up from the waveguide through a fundamental mode coupler.  The higher order modes of the waveguide provide the interfering signals alone, representing the difference beam which will be aligned along the boresight.  In a circular waveguide, the TM?1 will yield a difference pattern for vertical polarization in any plane, and a TE?1 or TE?1 mode will result in a difference pattern for horizontal polarization.  A square or a rectangular waveguide could be used instead of a circular waveguide to achieve the same result.  The higher order mode signals are processed through a delay line and weighting circuit, also known as the least mean square loop, and then summed with the fundamental mode signals to derive the desired signals substantially free from undesired, interfering signals.

Abstract: "MULTIPLEXED PSR DEMODULATOR"                  Abstract An improved quadrature differential phase shift keyed signal demodulator for use in a modem is shown.  A delay circuit (12) delays an input signal for a portion of a baud time.  Synchronous detectors (21, 23) mix the original and delayed input signals with coherent reference signals to obtain detected outputs which are alternately provided to a processor (60) by a multiplexer (25).  The processor (60) determines the phase shift and provides the demodulated data.  An offset baud clock phase locked loop (40) provides a baud clock which is offset by a ninety degree phase lag.  The offset baud clock causes the multiplexer (25) to provide detected outputs to the processor (60) for the center one-half of each baud. The result is a demodulator with fewer components and an improved data error rate.
