  • Patent number: 4768224
    Abstract: A device for enabling call forwarding instructions to be given from any telephone need be connected only to the phone line for which call forwarding service has been procured and does not require another phone line to communicate with the device. The device stores the call forwarding instructions in a recorder. The device detects the short ring that occurs on the procured service phone line when a call is forwarded and detects the long ring that occurs when call forwarding is not in effect. Upon detection of a short ring, the device seizes the procured service phone line and places a phone call to the phone line to which the previous call was forwarded. In an alternate embodiment, the device places the phone call to its own procured service phone line. In both embodiments, the device is reset to its stand-by state upon detection of a busy signal. Where a busy signal is not detected, the device transmits a signal that cancels call forwarding and triggers a timer.

  • Patent number: 4698015
    Abstract: An installation for monitoring combustion to control pollution and retard other deleterious effects of improper combustion employs a smoke sampling duct to draw off a portion of the smoke emanation from the combustion chamber. The smoke in the sampling duct flows past a probe and is then vented from the duct. The probe senses oxygen or other substances in the smoke and emits signals to a device which analyzes the quality of combustion. A gas inlet in the sampling duct is situated upstream of the probe and gas is intermittently discharged into that duct to ascertain whether the probe is operating properly.

  • Patent number: 4687993
    Abstract: A magnetic field sensing transducer which converts magnetic field intensity into a magnetostrictive strain and transfers that strain to an optical fiber employs a thin wall, hollow, cylindrical shell around which is wound a ribbon of an amorphous metallic magnetostrictive material. In another embodiment, the entire shell is formed by turns of the ribbon of magnetostrictive material. The optical fiber is coiled around the magnetostrictive cylinder formed by the wound ribbon and at both its ends, the optical fiber is affixed to the shell. The shell is covered at both its ends by caps and forms a thin wall resonator having three normal axisymmetric modes of vibration. The torsional vibratory mode is here of no interest because it does not appreciably couple to the optical fiber. Any one of the other two axisymmetric modes of vibration can be made dominant by selection of the appropriate length to radius ratio of the cylindrical shell.

  • Patent number: 4676091
    Abstract: The porosity of a strip of material is continuously computed by causing air to be drawn through the material as the strip moves across a perforated head situated atop a chamber in which the pressure is reduced by suction. In one embodiment, the reduced pressure is held substantially constant while the amount of air drawn through the chamber is measured and the porosity is determined by a computer whose inputs include the measured volume of air flow through the chamber and the speed at which the strip moves across the head, in addition to other inputs. In another embodiment, the volume of air flowing through the chamber is held substantially constant while the pressure in the chamber is measured and used as an input to the computer. In both embodiments, the speed at which the strip moves across the head is employed as a factor in the porosity computation.

  • Patent number: 4672841
    Abstract: The invention relates to a measuring head for measuring the porosity of a moving strip of porous material. The measuring chamber of the measuring head is covered by a measuring plate in which measuring openings are provided. For porosity measurement, air is sucked in through the porous strip and the measuring openings into the measuring chamber. The amount of air flowing into the measuring chamber is measured by a measuring arrangement connected to the measuring air connector and serves as a measure of the porosity of the strip. The measuring plate is surrounded by a guide plate which partially overlaps a blowing ring. The guide plate and blowing ring together form a blowing slot surrounding the measuring plate, the blow-out opening of which is directed outwardly and tangentially to the lower surface of the moving strip. The necessary blowing air is introduced via a connector into an annular channel, which is formed from a semi-circular groove in the blowing ring and merges into the blowing slot.

  • Patent number: 4670900
    Abstract: A device for enabling call forwarding instructions to be given from any telephone in the system or in any connecting system need be connected only to the phone line for which call forwarding service is provided and does not require another phone line to communicate with the device. The device employs a ring detector to detect the short ring that occurs when a call is forwarded and to detect the long ring that occurs when call forwarding is not in effect. Upon the detection of one or more short rings, the device seizes the phone line, transmits a "73" signal that cancels call forwarding, and triggers a timer that starts upon a timing interval of preset duration. If another phone call is received at the device within the preset timing interval and an authorization code is transmitted within that interval, the device enables the call forwarding instructions stored in a recorder to be changed.

  • Patent number: 4638445
    Abstract: A vision system for a mobile robot employs at least two arrays of sensors for obtaining data on the position and distance of objects in a workspace. One of the sensor arrays is used principally to see near objects and the other array is used principally to see far objects. The two arrays are symmetric about an axis that extends through the body of the robot. The robot carries a computer which controls the sequence in which the sensors are serially polled for information. Data received from the sensors is stored and provides a representation of the space and objects seen by the sensors. A software program causes the computer to manipulate data from the sensors to simulate rotation of the robot around the axis of symmetry and control behavior of the robot to complete goals set by input commands from a natural language processor.

  • Patent number: 4637244
    Abstract: A meter prover employs a piston arranged to slide in a bore within a proving cylinder which is coaxially disposed within a surrounding cylindrical shell. The effective area of the upstream face of the piston which can be acted on by fluid pressure is less than the effective area of the downstream face of the piston. In a proving run, fluid flow to the meter to be proved is diverted to an inlet in the shell upon closure of a bypass valve. The diverted fluid then flows through an annular space between the proving cylinder and the shell, enters the upstream end of the bore through openings in the cylinder, and drives the piston downstream along the cylinder in synchronism with the flow. Upon reopening of the bypass valve, equal fluid pressures act on the upstream and downstream faces of the piston and the difference in effective area of those faces causes the piston to return to the position it had at the start of the proving run.

  • Patent number: 4635269
    Abstract: A flowing gas laser of the kind normally operating in the glow discharge mode and having a glow discharge region through which the gas flows while the glow discharge occurs, employs one or an array of flow smoothing screens disposed in series in the gas flow path in a manner that enables the input power loading to be increased without causing arcing in the electric discharge of the lasing gas. The screens are disposed upstream of the glow discharge region and cause smoothing of small scale turbulence in the gas flow. The screen closest to the discharge region is spaced from the beginning of that region by a distance not less than ten times the distance between adjacent holes of the screen. Successive screens in the series array are spaced at intervals sufficient to enable the requisite flow smoothing by each screen to occur before the flow encounters the next screen of the array.
