Title: Caller controllable incoming telephone call signalling device
Inventor: SARAVANAN THIAGARAJAN
IPC: H04M11/02
Filed: 1992-04-21
Abstract: ABSTRACT OF THE DISCLOSURE   A device which is adapted to be connected to a telephone line and which produces instead of the conventional ringing sound for indicating an incoming call any one of a number of predetermined patterns of output signals.  The device includes a ring detector for detecting incoming ringing signals on the telephone line and outputting a ring detect signal in response to the ringing signals to a controller, a memory device for storing an operating program for the device along with a prompt signal pattern and a plurality of different signal indicating patterns, a hook switch for sending a signal out over the telephone line when instructed to do so by the controller which causes the incoming ringing signal to be terminated, a DC voltage sensor for sensing the DC voltage of the telephone line, a prompt generator for sending the ring back signal back out on the telephone line, the prompt signal being slightly different from a conventional ring back signal and an electrically actuated signal indicator emitting a preselected output signal pattern indicating an incoming call.  In the absence of a DTMF signal, the signal indicator will output a preselected one of the output signal patterns.  On hearing the ring back signal the caller may, (if he so desires), send a DTMF tone signal over the line to the device.  A DTMF decoder receives and decodes the DTMF tone signal and sends corresponding data signals to the controller.  The controller in turn causes the signal indicator  to emit a particular pattern of signals, the particular pattern being obtained from the memory device and being the pattern assigned to the particular DTMF tone signal that is sent by the caller.  As can be appreciated, each output signal pattern may be used to indicate an incoming call to a different person in the callee's household.

Title: Towed multi-band decoy
Inventor: TUCKER TREVOR W
IPC: H01Q15/20
Filed: 1992-06-26
Abstract: ABSTRACT           The towed multi-band radar decoy or target is a collapsible, airstream-inflatable device intended to be used for providing gunnery practise or electronic countermeasure protection for aircraft against radars and radar-guided missiles by being towed on a line behind the aircraft and offering a more attractive radar target than the aircraft for the radar or radar guided missile to track and home on.  The decoy or target is collapsible, so that many can be stored in a small space, and can be deployed while an aircraft is airborne.  The decoy is comprised of a sleeve of radar-transparent fabric having a tapered cylindrical shape and an open mouth at a narrow end, and clusters of orthogonal trihedral corners formed from flat conductive surfaces fixed inside and to said sleeve which can be folded and collapsed into a small space, and once inflated, for providing a radar reflective signature which exceeds that of a towing aircraft over predetermined angular aspects.

Filed: 1991-01-31
Abstract: A faucet assembly (22) with removable filter (105) has a bottom housing portion (111) attached to a source of water. A top housing portion (119) that includes a spout means (122) attaches and detaches from the bottom housing portion. A valve assembly (112) carried in the bottom housing is movable between a closed position, blocking the passage of water through the bottom housing portion into the attached top housing portion, and an opened position permitting the passage of water through the bottom housing portion into the attached top housing portion.

The filter breaks the sealing engagement as the top housing portion is detached from the bottom housing portion to permit removal of the filter from the detached top housing portion without otherwise disconnecting the faucet from the water source.
Patent CA-2082314-A1 (CA)
Inventor: LITCHFORD GEORGE B
IPC: G01S3/20
Filed: 1992-11-06
Abstract: The range from which transponder replies can be received at a virtual secondary surveillance radar of the type described in U.S. Pat. No. 4,115,771 is extended by replacing the omnidirectional antenna previously utilized to receive replies from transponders within the range of the SSR with a stationary array of a plurality of directive antennas arranged in a circle and having radiation patterns pointing in different directions from the center of and covering a respective sector of the circle, and sequentially switching on the antenna of the array covering the sector in which the rotating beam of the associated SSR is then pointing.  In an arrangement in which the SSR and PSSR are so widely separated that in certain pointing directions the SSR beam overlies more than one sector of the antenna array, the antennas are sequentially switched on at calculated switching times determined from the pointing direction of the SSR beam and the times it takes in the geometrical arrangement between the SSR beam and the radiation patterns of the antennas of the array, for a given SSR interrogating pulse to propagate, from launch, along the beam until it reaches the line separating the first encountered sector from the next adjacent sector, between second and third sectors, and so on, such that a high gain directive antenna is always pointing in the proper direction to receive reply signals from a transponder intercepted by the scanning beam of the SSR.
