Title: Optical fibre cable
Inventor: GANNON JOHN R
IPC: B29D11/00
Filed: 1986-10-03
Granted: 1992-02-11
Abstract: OPTICAL FIBRE CABLE Abstract of the Disclosure An optical fibre cable element (3A) for incorporation in an optical fibre cable (Fig. 4) for e.g. local area networks, comprises a plurality of optical fibres (3) held together solely by an adhesive which has been applied cold and air-dried.  A suitable adhesive material is a solvent-based acrylic copolymer system.  Preferably the shape of the cable element is a ribbon, but other constructions are also envisaged.  The cable element is cheap to make and avoids the heat and pressure of extrusion in the construction of the cable element, thus minimising the risk of damaging the fibres by such heat and pressure.  Very high fibre density is also achieved.

Title: Control stop for flushing system
Inventor: JOHNSON DWIGHT N
IPC: E03D3/00
Filed: 1986-10-27
Granted: 1991-01-29
Abstract: CONTROL STOP FOR FLUSHING SYSTEM   Abstract of the Disclosure A control stop for a flushing system includ-ing a metering flush valve connected to supply liquid to a toilet fixture.  The control stop is in series flow relation between a source of pressurized liquid and the metering flush valve and serves the several functions of controlling flow to the metering flush valve for reducing noise and maintaining desired flush-ing action, preventing reverse flow and trapping pres-sure at the metering flush valve in the event of loss of inlet pressure, and shutting off the flow path for installation, service or replacement of the metering flush valve.  The control stop includes a regulator having a valving portion engageable with a valve seat communicating with the outlet of the control stop and acts as a low pressure cut-off rather than a check valve.  A spring biases the regulator toward the valve seat and the regulator is normally held open by liquid pressure.  A stop member is adjustable to limit the opening movement of the regulator for flow control, and can be moved to a position closing the regulator valving surface against the valve seat to shut off the liquid flow path.

Granted: 1991-10-01
Abstract: ABSTRACT            Title:  Molecular Sieve Bed Containers A molecular sieve bed container provides a plurality of molecular sieve bed chambers.  The chambers are formed by tubular wall members concentrically located within a tubular outer housing and are closed at their ends by end closure members.  One end closure member incorporates valves (not shown in Figure 1) for controlling supply of charge gas to the sieve bed chambers and venting of purge gas from the sieve bed chambers.  The other end closure member incorporates valves for controlling passage of product gas from the sieve bed chambers to an outlet (not shown) and portways for permitting some of the product gas to flow back through the sieve bed chambers as purge gas during a purge/vent phase.  In the illustrated embodiment three sieve bed chambers are filled with a molecular sieve material which is given to removal of nitrogen from air supplied to the container as charge gas whilst two chambers are filled with a molecular sieve material which is given to removal of oxygen whereby supplies of oxygen-enriched air and nitrogen-enriched air are delivered as product gases.

Granted: 1991-08-27
Abstract: Abstract of the Disclosure A cold weather breathing device which heats and humidifies air to be breathed.  A face mask which covers the mouth and nose includes intake and exhaust ports each equipped with a one way valve.  An open sided conduit which is U-shaped in section extends in opposite directions from the mask along opposite sides of the head.  A corrugated metal partition divides the conduit into side by side intake and exhaust passages.  The intake passage is adjacent the open side of the conduit so that incoming air flowing through the intake passage is directly heated and humidified by the face, head and neck.  The heat from the exhaled air in the exhaust passage is also transferred to the incoming air through the partition.

Title: Phase locked loop stabilization circuitry

IPC: H03L7/22
Filed: 1987-03-27
Granted: 1992-07-28
Abstract: RCA 82,969 Abstract of the Disclosure A digital television receiver includes a first phase locked loop which develops a sampling clock signal that is locked to the horizontal line synchronizing signal components of a composite video signal.  A second digital phase locked loop is clocked by the sampling clock signal and develops a digital signal that is phase locked to the color burst signal.  This digital signal is used as a regenerated color subcarrier signal to synchronously demodulate the chrominance components of the composite video signals into I and Q color difference signals.  To compensate for frequency instability in the regenerated subcarrier signal caused by frequency instabilities in the line-locked clock signal, a third digital phase locked loop develops an output signal which is phase locked to a reference signal generated by a crystal controlled oscillator.  Control signals from -the third phase locked loop are applied to the second phase locked loop to substantially compensate for frequency instabillties in the regenerated subcarrier signal that are induced by the clock signals.
