摘要： A motor circuit interrupter characterized by a manually operated fast-acting switch and a bi-metallic over-load relay for trip opening of the switch contacts in response to current overloads. The switch comprises means for moving electric contacts between open and closed positions which means includes a releasable arm which is movable between latched and unlatched positions. When in the ''''unlatched'''' condition, the contacts are open and the operating means cannot be operated to effect a re-closing of the contacts. The switch further comprises a pivoted latch lever operatively connected to the releasable arm to retain the arm in the latched condition, or for effecting unlatching of the arm, a latch retainer lever to retain the latch lever in the latch position said retainer lever is operatively connected to the trip plate of the overload relay to effect unlatching of the latch lever and releasable arm in response to an overload current. The retainer lever is spring-biased to the latch position with the latch lever and the retainer lever comprising an extension engageable with the latch lever when the latter is in the unlatched position to maintain the latch lever in a relatching position.

摘要： An electrohydraulic emergency trip system for a turbine power plant to close rapidly the steam inlet valves to the turbine is disclosed. The hydraulic portion of the system for decreasing the trip fluid pressure to the steam inlet valves is governed by a first and second electrically operable trip valve means, both of which are operated to trip the turbine. Each of the trip valve means is controlled by an independent voltage source. A contingency detection means, which operates in response to a trip contingency, is energized by a third voltage source that is generated by one or both of the first and second voltage sources. The system provides for ground fault detection upon testing for a trip contingency.

摘要： A combustion technique is employed to combustively react oxygen with carbon monoxide present within a gas mixture and to combustively react oxygen with the total combustibles content of the gas such that the carbon monoxide content and reactive hydrocarbon content of the gas is determined on the basis of the oxygen required to produce stoichiometric reactions with the carbon monoxide and the total combustible content of the gas. The technique employs the use of a hydrocarbon trap which traps reactive hydrocarbons, i.e., those typically resulting in the development of pollutants and smog, while passing hydrocarbons such as methane which generally do not react to produce undesirable pollutants and smog.

摘要： The structure of and the method of processing is disclosed for providing a MNOS element comprised of diverse regions within a semiconductive member. A first silicon oxide layer is disposed to cover a first portion of the semiconductive substrate, other than that in which the MNOS element is formed. A second silicon oxide layer is disposed to cover a second portion of the semiconductive member in which the MNOS element is formed. A conductive element is connected to one of the MNOS regions and overlies the first portion of the member. A first layer of a nitride such as Si3N4 is deposited at a rate in the range of 40 to 60 A/minute to cover the silicon oxide layer, whereby a nitride-oxide interface charge of a magnitude and polarity is established to inhibit the formation of a parasitic region within the semiconductive member, due to the application of a voltage signal to the conductive element. In a further aspect, either or both memory and non-memory MNOS elements may be fabricated in a manner to include drain and source regions spaced from each other with its second silicon oxide layer covering the channel formed therebetween, and a gate electrode disposed thereon. In the formation of a memory MNOS element, the second oxide layer covering the second portion of the member is reduced, e.g. by etching, to a thickness in the order of 7 to 9 A. Next, in the fabrication of both memory and non-memory MNOS elements, a second nitride layer is deposited at a rate in the order of 75 to 150 A, whereby the nitride-oxide interface charge is minimized. A plurality of such memory MNOS elements may be formed into a matrix, wherein the row and column conductors are insulated from each other. The deposition of the first nitride layer at the rate specified above inhibits the formation of parasitic regions beneath the row and column conductors. Further, memory and non-memory MNOS elements may be fabricated upon a common semiconductive substrate by simplified fabrication techniques. In particular, the second deposition of silicon nitride is carried out at a rate in the order of 100 A/minute, whereby a minimum nitride-oxide interface charge is established to ensure the effective operation of the non-memory MNOS element and to increase the memory hysteresis window of the memory MNOS element.

摘要： Modular operating centers for use in electric power generating plants and other industrial and commercial plants, processes and systems are constructed by using a novel prefabricated modular technique. This technique includes loading a plurality of transportable room-size building modules with control system equipment at a factory site. Typically, the control system equipment includes sophisticated and complex electrical and electronics data processing and control equipment. The control system equipment is installed and bolted down in the different building modules and the equipment in each module is inter-wired at the factory site. Temporary inter-module connections are established between the control system equipment in different ones of the building modules and such equipment, as a whole, is then thoroughly tested and adjusted under simulated use conditions. Thereafter, the loaded and tested building modules are separated and separately transported to the industrial or commercial installation site. At the installation site, the building modules are joined together to form an integral weatherproof building structure and the inter-module control system equipment connections are re-established to provide a tested and substantially ready-to-go control center for the plant, process or system in question. A novel feature of this technique is that structural building modules are used as the shipping containers for transporting complex electrical and electronics equipment to the final installation site.

摘要： A boiler-steam turbine plant control system for transferring between boiler-follow, turbine-follow, and coordinated operating modes, without any change in the output of the turbine or the firing rate of the boiler, is disclosed. A feedforward load demand signal controls both the turbine and boiler in parallel. In the turbine-follow mode, a feedback loop trims the feedforward signal to the turbine only. In the boiler-follow mode, a feedback loop trims the feedforward signal to the boiler only. In the coordinated mode, feedback loops trim the feedforward signal to both the turbine and boiler. In response to initiating a transfer to either the boiler or turbine-follow mode, the load demand signals which are controlling the boiler and turbine are held at their pre-transfer value; and the feedforward signal is modified to equal the pre-transfer value of the trimmed feedforward signal. A signal, which is equal in value to the pre-transfer value of the feedforward signal less the value of the trimmed feedforward signal is generated in the output of the feedback loop which is to be placed in service as a result of the transfer. To transfer to the coordinated mode, the feedforward signal is modified to equal a signal representative of the actual power output of the plant. The turbine feedback loop generates a signal representative of the pre-transfer turbine demand signal less the modified feedforward signal. The boiler feedback loop generates a signal representative of the pre-transfer boiler demand signal less the modified feedforward signal.

摘要： Periodic signals, for example sonar returns, to be displayed on a conventional television monitor are sampled and put into storage registers at a first rate. The storage registers are emptied at a second rate and the information is placed onto a video magnetic disk. For each sonar transmission a number of samples of the return signal are placed into, and read out of, the storage registers, during each revolution of the disk, as the return is coming in, to build up a television display signal indicative of the sonar return.
