摘要： A line switch for a digital telephone switching system utilizes distributed processing. The line switch comprises one or more switch modules. Each switch module is coupled to a central office switching system via one or more PCM lines which utilize common channel signaling. Each switch module comprises groups of line circuits, each line circuit being coupled to a subscriber line. Three separate distributed processor functions are provided in each line switch module. A first processor is utilized to communicate with the central office switching system and to coordinate the operations within the line switch module. A second processor is provided to control clock generation and rate conversion circuits. Each group of line circuits includes a third processor to control the operations of the line circuits and to gather information from the line circuit. A busing arrangement is provided within the line switch such that both control information and PCM voice data are routed throughout the line switch.

摘要： A suspension of a finely divided material in a liquid suspending medium which swells cellulose, the suspension containing microfibrillated cellulose in an amount sufficient to produce a stable, homogeneous suspension. The microfibrillated cellulose, a form of cellulose having a very large available surface area per unit of weight, acts to confer, among other benefits, greater stability on the suspension. The suspensions are useful in a variety of end use products including foods, cosmetics, pharmaceuticals, paints and drilling muds.

摘要： A diaphragm pump pumping arrangement includes two diaphragm pumps which are arranged and operate in tandem. Each of the diaphragm pumps includes a housing and a movable wall that includes a flexible diaphragm and subdivides the interior of the respective pump housing into a pumping chamber and an actuating chamber. An air distributing control arrangement interposed between and connected to the pump housings includes a spool valve movable in a bore of an aluminum casing of the control arrangement between two end positions in which it alternatingly achieves the admission of the compressed air into one, and discharge of the air from the other, actuating chamber. The spool valve is displaced due to the action of respective switching valves accommodated in individual bores of the control arrangement and displaced by the respective movable walls from their rest positions in which they admit the ambient pressure to the associated end faces to their active positions in which they admit the compressed air to the associated end faces of the spool valve. Each switching valve has an actuating portion that passes through a central passage of an annular element stationarily mounted in the respective bore, with a greater clearance at first, and with a lesser clearance later. A substantially radial passage in the annular element opens onto the zone of the central passage upstream of the lesser clearance, so that compressed air propagates into the radial passage unless prevented from doing so by a seal in a first position of the switching valve, and the lesser clearance provides a throttling action at all times, assuring pressure relief in the radial passage when the seal is in effect.

摘要： A metallic material coating is applied to the external surface of a freshly drawn optical fiber while such surface is still pristine by passing the optical fiber through a body of liquid metal-organic material which forms a layer on the fiber, and by subsequently removing all non-metallic components from the layer of metal-organic material by volatilizing the same. The optical fiber with the layer metal-organic material is passed through a baking oven in which at least the layer is heated to a baking temperature at which organic materials present in the metal-organic material are volatilized and the remainder is baked to the fiber. Then, at least the layer is fired in a firing chamber at a higher temperature at which the metal-organic material is decomposed into its volatile non-metallic and non-volatile metallic components, the latter remaining in the layer and the former becoming volatile and leaving the layer. Preferably, at least one layer of synthetic plastic material is applied over the thus obtained metallic layer. When the firing is done in an inert or reducing atomsphere, the metallic material is in its elemental form, while it is in its metal-oxide form when the firing operation is accomplished in an oxidizing atmosphere. Various printing inks and/or resinates may be used as the starting metal-organic materials in the process according to the invention.

摘要： A gate member for a gate valve provides improved sealing by providing for proper orientation of the gate member as it approaches its closed position and then providing improved sealing action as the gate member is closed further. A lip on the gate member overlaps a ledge on the valve body at the opening where the gate member enters the valve chamber. The lip is covered by a seal of resilient material having a cross-sectional shape that cooperates with the valve body to orient the gate member and that controls the compression of the seal between the lip and ledge as the gate member closes further. The shape of the gate member also helps to orient it while it is closing. A spine and a ridged cap of resilient material on the leading edge of the gate member cooperate to prevent blow-by of pressurized fluid when the gate member is closed. Pads integral with the seal contact the corners of the opening initially to orient the gate member and then to fill the corners when the gate member is closed further.

摘要： A demodulator of the type employed in a "zero-IF" system uses a local oscillator for providing guadrature output signals at the center frequency of an FM signal to be demodulated. The demodulator has first and second mixers for separately mixing the FM signal with the quadrature signals to provide a first and second output signal each in quadrature at the outputs of said mixers. These signals are low pass filtered. The demodulator includes third and fourth mixers with each mixer receiving at an input one of the low pass signals. At another input the mixers receive third and fourth signals. The third and fourth signals are derived from mixing a variable controlled oscillator (VCO) signal with the local oscillator guadrature signals. The outputs of the third and fourth mixers are applied to the inputs of a difference amplifiers, the output of which controls the frequency of the VCO in an automatic frequency control mode (AFC) to cause the output of the difference amplifier to provide demodulated signal.A switching means operates to alternate the third and fourth signals as applied to the input of the third and fourth means as well as the output as applied to the difference amplifier to cause an additional amplifier coupled to the outputs of the mixers to provide a DC control signal used for automatic gain control.

摘要： A self-contained spring biasing device, particularly useful for providing a movement-resisting force on the power shaft of a valve actuator, comprises spring cartridge means and safety means. The spring cartridge means has therein a compression spring and a bearing plate that is pushed by the power shaft to compress the spring and resist movement of the shaft. The safety means is accessible from the exterior of the spring cartridge means and removably secures the power shaft to the bearing plate, thus preventing the spring from launching the spring cartridge means from the actuator.

摘要： A seat position control device for a powered or automatic seat adjusting mechanism for motor vehicles. The motor drives for the various adjustments uses a motor with a predetermined number of poles. Thus, for each revolution of a motor, a predetermined number of pulses is generated. By counting these pulses relative to a reference, the position of the seat can be determined. Within memory, a desired location setting may be registered to return the seat to that setting when desired. A commercially available microprocessor or suitable electronic components may be used as the logic and memory medium.
