Title: Variable band-pass filter circuit
Inventor: NOMURA HIROSHI
IPC: H03H11/04
Filed: 1991-09-27
Granted: 2000-10-24
Abstract: A variable band-pass filter circuit includes a variable band-pass filter which filters an input signal such as a chrominance signal. An output the variable band-pass filter is phase-compared with a reference signal in a phase comparator. An output of the phase comparator is applied to the variable band-pass filter as a control signal. The output of the variable band-pass filter is level-limited by a limiter and then applied to an adder which further receives the reference signal. One of the input signal arid an output of the adder is selected by a switch to be applied to an input of the variable band-pass filter. A reference signal component is removed by a sample hold circuit to be prevented from being outputted from an output of the variable ban-pass filter.

Abstract: A lead-free composition capable of being applied as a film and hardening to form a protective layer on the back of a mirror comprises  a fluid organic  resin  and  a  corrosion  inhibitor  selected from the group consisting of dicyandiamide, metal or acid salts of dicyandiamide, hydrogen cyanamide, and 2-cyanoacetamide.    The  organic  resin  may  be  any thermoplastic  or thermosetting  resin  suitable  for coating the reflective and other metallic layers of the mirror.   Exemplary resins include alkyd resins, acrylic  resin,  modified alkyd resins,  polyesters, urethane oils, vinyl halide polymers or copolymers, oleoresinous varnishes, nitrocellulose compositions, phenol-formaldehyde  resin  varnishes,   and  epoxy resins.    Preferably,  the  resin  is  an  alkyd  or modified alkyd resin.   The aforementioned corrosion inhibitor may be present in an amount from about 0.1 to 20 weight percent, preferably 0.5 to 10 weight percent, of the organic resin coating system.   The resin system should be essentially free of lead and lead salts.   To inhibit the corrosion of metallic film layers on mirrors,  a   mirror having a glass substrate layer and a metallic film layer thereover should be obtained,  after which the fluid organic resin coating system containing the aforementioned corrosion  inhibitor  is  applied over  the metallic film layer.   The organic resin coating system is then  hardened  to  produce  the  protective  coating layer  over  the  metallic  layer.    Other  articles having metallic surfaces may also be protected by the  resin  system  containing  the  novel  corrosion inhibitor of the present invention.

Inventor: RIORDAN KENNETH B
IPC: H04B1/10
Filed: 1992-01-08
Granted: 1995-12-12
Abstract: A receiver (200) automatically compensates for intermodulation of an input signal. The receiver (200) is preceded by a re-ceiver front-end (105) which is coupled to antennas (100-102) receiving the signal. The gain of the antenna path/frequency is cali-brated and stored for all combinations of antenna path/frequency. When a signal is received, the receiver (200) determines the correct stored gain factor representing the antenna receiving the signal and the frequency of the signal. The gain factor is com-pared against a predetermined threshold, and if the gain factor is greater than the threshold, an attenuator (400) placed at the front of the receiver (200) is inserted to optimize signal intermodulation. If the gain factor less than the threshold, the attenuator (400) is bypassed to optimize the sensitivity of the receiver (200).

Granted: 1996-10-08
Abstract: The invention relates to signalling, particularly road signalling,  means.  A considerable variety of illuminated and reflective  signalling means are known to give advice  to  the driver  of  a  particular vehicle and of great  value  to  the driver  of  a  vehicle during the hours of darkness  on  unlit roads  or  in inclement weather where mist and  fog  shroud  a road.    Such   known  signalling  means  cannot  satisfy  the important need to give advice to a driver of a vehicle of  the presence  of  another vehicle closely ahead, and which is  of particular  importance  in misty  or  foggy  conditions.   The primary  objective of the invention is to provide a signalling means  that can satisfy this requirement,  which objective  is met by a construction comprising at least one  means  (7,  C3) able  to be charged by light from a vehicle headlight,  and  a visible signal means (8;  13,  15)  connected to and activated by  said  chargeable  means (7,  C3),  and  whereby  on  being charged,  said chargeable means (7,  C3) activates said signal means  (8;  13,  15) for a discrete period of time after  said headlight  has ceased to illuminate said chargeable means  (7, C3)  and until said chargeable means (7,  C3) has  discharged.         As a result, a trail of signals is permanently provided behind a  lead vehicle  to give warning to a vehicle behind  of  its presence  and  to a distance that constitutes a  safe  braking distance.

Title: Showerhead
Inventor: CAMMACK MICHAEL A
IPC: B05B3/04
Filed: 1993-07-16
Granted: 1999-01-12
Abstract: A showerhead is either wall mounted or provided with a handle connected through a flexible hose to an incoming water outlet.  The showerhead has a turbine which may cause the delivery of pulses of circumferentially distributed groups of pulses of water so as to provide either fast or slow massage action. Also included is a pause mode in which flow is reduced without complete shutoff and a center spray mode which provides a concentrated spray pattern.  Other modes possible are a needle spray, a combination pulse and needle spray, a combination needle spray with a body spray and just a body spray.  Various water paths are defined from a flow selector through the unit to different ones of front-facing orifices as defined for the different modes.  Selection is achieved by a combination of a flow director and a control plate. User access for mode selection is by way of an external circumferential control ring operatively coupled to the control plate through a control arm.  A component is removable by the user to enable easy cleaning of an array of the outlet orifices.

Title: Method and apparatus for the measurement of atrial pressure
Inventor: HICKEY DONALD D
IPC: A61B5/03
Filed: 1991-06-24
Granted: 1999-05-04
Abstract: A non-invasive apparatus for obtaining a quantitative determination of mean left atrial pressure comprises a balloon (24) to be inserted by means of a catheter (20) into the esophagus (26) and positioned adjacent the left atrium.  As the balloon is gradually inflated, a tracing of mean balloon pressure is obtained. In addition, a tracing of balloon pressure on a steady baseline and with low frequency oscillations due to respiration filtered out is obtained whereby the tracing represents balloon pressure oscillations effected by left atrial pressure. In accordance with the oscillometric principle the mean balloon pressure is measured at the time when the amplitude of the balloon pressure oscillations effected by the left atrial pressure is at a peak. This mean balloon pressure is indicative of approximate mean left atrial pressure. Mean left atrial transmural pressure may be determined by subtracting therefrom the mean esophageal pressure as measured at a position in the esophagus where it is unaffected by the heart.
