Title: Noise suppression system
Inventor: VILMUR RICHARD J
IPC: H04B15/00
Filed: 1989-09-22
Granted: 1992-10-06
Abstract: ABSTRACT OF THE DISCLOSURE         An improved noise suppression system (800) is disclosed which performs speech quality enhancement upon the speech-plus-noise signal available at the input (205) to generate a clean speech signal at the output (265) by spectral gain modification.  The improvements of the present invention include the addition of a signal-to-noise ratio (SNR) threshold mechanism (830) to reduce background noise flutter by offsetting the gain rise of the gain tables until a certain SNR threshold is reached, the use of a voice metric calculator (810) to produce more accurate background noise estimates via performing the update decision based on the overall voice-like characteristics in the channels and the time interval since the last update, and the use of a channel SNR modifier (820) to provide immunity to narrowband noise bursts through modification of the SNR estimates based on the voice metric calculation and the channel energies.

Title: Threaded tubular connection
Inventor: KLEMENTICH ERICH F

Granted: 1993-10-05
Abstract: ABSTRACT    Threaded tubular interference fit interconnections and related production techniques are disclosed that are useful with large diameter tubular members, including pipe bodies, that can function as casing for oil, gas, geothermal, disposal and other wells. Preferably there is root-to-crest and/or flank-to-flank interference between nose and inner portions of male and female threads of the disclosed interconnections, to substantially seal them against leakage at the internal and/or external pressure rating of the pipe body, and a run-out portion of the male thread and a corresponding portion of the female thread engage one another with interference to retain threaded engagement between said run-out and corresponding portions at the axial yield strength of the pipe body and also at the internal and/or external pressure rating of the pipe body. These connections, when applied to API line pipe or other tubular products, can allow them to properly function as large diameter casing exhibiting easy and economical manufacture with existing machinery, easy installation in the field, good balance between geometric and load capacity transparency, and freedom from some undesirable characteristics of prior products.

Abstract: Abstract of the Disclosure An electronic programmable thermostat for  the control  of  a furnace or air conditioner is useful as a replacement   for   a   conventional    non-programmable thermostat    and   mounts   on   the   non-programmable thermostat's wall plate to achieve  support,  electrical connection  with  the load and power supply, and the use of certain manual controls supported on the wall  plate.  The  programmable  thermostat employs a circular printed circuit  board  supporting  its  electronic  components, which include a potentiometer for operator adjustment of desired temperature.  A flat circular knob supported  on the  potentiometer  shaft and an annular bezel cover the thermostat and  allow  access  to  the  manual  controls supported  on  the  wall plate.  The potentiometer and a temperature sensing thermistor control the frequency  of a  pulse  generator  which  provides input to a counter.  The resulting digital signal is compared with a  digital signal  generated  under control of a clock and manually actuable programming switches,  to  generate  an  output control signal for the load.

Abstract: A technique for monitoring scouring around structural members which are at least partially submerged in the soil bed material at the bottom of a body of water, the distance between a fixed point on the structural member and the topmost portion of the soil bed material near the member is determined and compared to a predetermined value.  When scouring occurs, removal of some of the soil bed material results in an increase in the measured distance, which increase can be used to indicate the occurrence of scouring in an appropriate manner, such as by utilizing a display, by recording the data, or even by telecommunicating the data to another location.  The distance determination may be made either only when called for or periodically at predetermined times, in order to provide continuous monitoring.

Date Jun. 9, 1983.A self-retaining post of a plastic material, such as PVC, for use as a roadside marking post, a traffic sign post, a lamp post, or for other comparable uses in road traffic environments, has a channel-shaped bending zone with substantially arcuate cross-section and with the convex side facing the on-coming traffic. The cross-sectional area of the bending zone increases progressively towards the lower end, whereby the flaring-out zone formed upon bending of the post will be larger below than above the line of bending. The greater inherent resiliency of the material below than above the line of bending will cause the post to bend back into an upright position after having been hit by a vehicle. Certain embodiments of the posts are manufactured by diagonally splitting lengths of extrusion-molded plastic tubing, forming two identically shaped posts from each tube length.

Abstract: The flow box comprises an explosion chamber, having a base wall, top wall and two side walls. An outlet at the bottom of one side wall communicates with a slice chamber extending parallel to the base wall, and the number of inlet pipes connect the explosion chamber to a distribution chamber. The inlet pipes communicate with two rows of openings in the top wall of the explosion chamber and have an axial direction directed towards the base wall. A fist deflector has an upper surface which extends across the axial direction of the pipes of a first row of openings to form a divergent passage with the top wall. A second deflector extends from the other side wall across the axial direction of the pipes of the second row of openings. The second deflector has an upper surface forming a convergent flow passage with at least a part of the lower surface of the first deflector. - The flow box or head box is used to supply paper stock to a forming wire during the papermaking process. It provides a more uniform distribution of the stock across the width of the wire giving reduced variation of basis weight of the final web in the cross-direction.

Abstract: An on channel frequency agile PLL demodulator is provided using a precise and stable oscillator (82), such as a VCXO having its output frequency variable over a limited range. The output of the oscillator is multiplied (84) by a multiplication factor to produce a mixing frequency. The multiplication factor scales the limited range of the oscillator to produce a proportionate mixing frequency deviation. A frequency synthesizer (90) is used to enable the demodulator to detect signals on different channels. In one embodiment, the output of the frequency synthesizer (90) is mixed with the scaled oscillator output to provide a mixing frequency (fn) having a fixed deviation for all channels.

Abstract: A two-way interactive addressable entertainment terminal comprises a processor, a keyboard, a character generator responsive to the processor and memory for storage of an algorithm related to the installation of the terminal and to providing a verification indica-tion at the terminal of acknowledged entry of the terminal into an entertainment system. The character generator, responsive to the passage of a predetermined period of time since the application of power to the terminal, causes a number of screens to be displayed on an associated television receiver. The display screens reinforce the algorithm and provide indications of programmed key functions despite labels of keys on the keyboard. Consequently, a user or installer is capable of installing a terminal according to the present invention without any communication with personnel at the location of a system manager. By requiring the practically simultaneous occurrence of two events the application of power and the actuation of a predetermined key, inadvertent entry into either an installation mode or a maintenance mode of terminal operation is prevented.
