Inventor: WEST LAMAR E JR
IPC: H04N7/16
Filed: 1989-12-04
Abstract: An off-premises cable television interdiction apparatus provides a microprocessor controller for controlling and switching one or more variable frequency voltage controlled oscillators. The variable frequency oscillators selectively jam only unauthorized premium programming transmitted on particular channels of a broadband signal in the clear from a headend to a subscriber. The microprocessor controller controls the variable frequency oscillators to hop between jamming frequencies and jam particular channels under control from the headend. A frequency calibration routine is executed periodically upon power-up to determine gain parameters for the oscillators. A heterodyned variable frequency oscillator may be provided for the interdiction system which moves the frequency of the variable frequency oscillator out of the television band and mixes the variable frequency oscillator output with a fixed local oscillator output to provide a jamming signal that falls in the television band. Gain control using a heterodyned oscillator may instead be provided for use in the interdiction system which uses one channel of the broadband signal as the jamming signal. Automatic gain control may also instead be provided for controlling the attenuation of a variable attenuator in accordance with a gain function determined by interpolation and previously stored in memory by a calibration routine executed periodically or upon power-up. The calibration routine may run concurrently with a frequency calibration routine for controlling the frequency of the jamming signal.

Title: Television set with supervisory functions of alarming burglary and safe watching distance
IPC: G08B13/18
Filed: 1981-02-19
Abstract: A supervisory assembly incorporates a sensing means operatively associated with a TV set, so that one of the options available to the user is that when the sensing means detects someone it responds by altering the TV output. For example it may blank the screen, cut the TV power supply, or use the TV to make an alarm noise. 
<??>The sensing means has a detecting device (1), the output of which passes through a signal processing circuit (2) so as to operate a switch element (4). The switch element can operate a TV control means (6), to affect the TV output. Other, conventional, alarms (5,7) may also be operated by the switch element (4). 
<??>The assembly has use as a burglar alarm, and also for warning that someone is closer to the TV than a safe watching distance. In the latter case it is useful if the assembly's response is delayed slightly, so as to prevent it from giving the alarm when e.g. someone changes TV channel. 
<??>The sensing means may operate by emitting a signal (eg. ultrasonic) and detecting any reflection of it.

Inventor: KURKJIAN ANDREW
IPC: G01V1/44
Filed: 1985-12-27
Abstract: The shear velocity of a formation traversed by a fluid-filled open or cased borehole is obtained. Waveforms are obtained from a dipole acoustic investigation of the formation relative to a common location in the borehole. In a direct technique, the bandwidth of the waveforms is substantially bounded by an upper frequency fu at and below which energy traveling at the shear velocity is dominant. Moreover, the bandwidth of the waveforms is concentrated near the frequency  fu. The shear velocity of said earth formation is determined from waveforms obtained from a broadband dipole acoustic investigation. The waveforms are low-pass filtered, and an interim shear velocity vs is determined. Vs is first obtained for an initial fcut, and subsequently for additional decreasing values of fcut, until a preselected relationship between fcut and vs is satisfied. The last-determined vs is the shear velocity. In another embodiment the flexural mode phase velocity is determined as a function of frequency from the waveforms. If a low frequency asymptote is identifiable, it is reported as the shear velocity. If not, a plurality of additional curves of the flexural mode phase velocity as a function of frequency are theoretically determined, based on respective estimated shear velocities. These curves are respectively fitted to the curve determined from the waveforms, until a satisfactory least error fit is achieved. The last-estimated shear velocity is reported as a shear velocity of the formation.

Abstract: 1,141,190. Pneumatic conveyers. SIEMENS A.G. 5 Dec., 1967 [6 Dec., 1966], No. 55271/67. Heading B8A. [Also in Division F2] A device adapted to be selectively usable as an intermediate station, a transmitting station or a receiving station in a pneumaticallyoperated shuttle-conveying system comprises a housing 1 having travel tube connections 2, 3 which are in line on opposite sides thereof a pivotally mounted drum with two tubes 5, 6 diametrically opposite each other and a deflection component 10 on an exit flap 9 loaded by a tension spring 11. An air-tight dispatch flap 4 is provided. In the position shown in Figs. 1(a), 1(b) the device acts as an intermediate station or a transmitting station, tube 6 being in line with the connections 2, 3. By means of compressed air a shuttle is thus fed unimpeded through the station. When operating as a transmitting station tube 5 is in line with the flap 4 and a shuttle 27 may be introduced therein by a manner not indicated. With the aid of a selector device (not shown) at the station another station in the system is selected as the destination. A solenoid (15), Fig. 3 (not shown), is operated twice in a manner to index the drum through two steps, each of 90 degrees (see Division F2), tube 5 occupying the position of tube 6 in Fig. 1(b), and holding down the flap 9 in its turn. The compressed air blower (not shown) is then started and the shuttle 27 fed to its destination and extracted there. The compressed air forces the flap 9 against elastic surround 12 of exit aperture 8. To act as a receiving station the drum is indexed by one step of 90 degrees from the position shown in Fig. 1(b), to the position shown in Figs. 2(a), 2(b). A shuttle arriving through the tube 2 is deflected by the component 10 to strike the elastic surround 12 and to drop into a catcher container (not shown). After the shuttle 28 has been fed out the drum is indexed a further 90‹ so that the flap 9 is closed by tube 5 or 6. A toggle 13 on the drum spindle 7 locks the flap 4 when the device is set for receiving, so that shuttles cannot then be inserted into the housing 1.

[Also in Division H5] The heatable glass sheet of the parent Specification has its resistance bands 2 initially deposited by a screen-printing process. The stencil is produced in the printing fabric by coating the fabric with a light-sensitive copying solution, which is exposed to light through a diapositive corresponding to the printed pattern, hardened in the areas exposed and washed out in the unexposed areas. The printing fabric is held with its threads at an angle of between 14 and 76 degrees, preferably 45 degrees, to the bands when printed. Since the meshes are either completely closed or fully open, the bands formed from this fabric have regularly spaced projections along their sides forming a sawtooth outline, Fig. 2. Since electrodeposition favours such projections, the reinforcing conductive coating thereafter formed is uniform. The fabric is adhered to a printing frame 10 with the threads running diagonally thereof and is evenly tensioned by pumping up a rubber tube (12) fitted in a channel 11 around the frame.
