Abstract: A combination of a rotor and a stator assembly, the stator assembly having a first part and a second part, the first and second parts being generally concentric, the rotor being rotatably mounted in the stator assembly, the combination further including a plurality of elongate resilient damping elements which extend generally in an axial direction, and being located between and spacing apart the first part and the second part of the stator assembly.

Abstract: An electric motor assembly e.g. for an air cycle air conditioning apparatus comprises stator windings and a rotating member mounted for rotation about a motor axis and wherein, the stator windings comprise therethrough at least one axially extending passage, and there being means to connect the passage to a source of cooling gas, whereby as the cooling gas flows along the axially extending passage the motor assembly is cooled.

Abstract: The present disclosure is directed to a system for providing restrained, streamlined access to a computerized information source. The system--which works in association with a multipurpose computer--includes a discrete article, such as an advertising specialty like a mouse pad, having facilities to receive a user input and, in turn, generate a unique predetermined signal based on the input. The system further includes software for configuring the computer to respond to each unique predetermined signal by executing one or more commands, as selected and stored within the software. Each configuration can be dynamically locked such that the commands to be executed upon the unique input are not alterable without an authorization mechanism, such as a password. The software also responds to receipt of one of the unique predetermined signals by executing the commands associated with the received signal. A method for performing same is also disclosed.

Abstract: A synchronous computer system is described. The system is a multiprocessor system having a bus system clock and a processor clock for each processor. The system includes a synchronous computer system bus and a plurality of circuit modules coupled to the synchronous bus with at least two of the modules having at least one processor, with the processor modules having the at least one processor which runs asynchronously to each of the other processors while the processor modules are synchronous to the system bus. The system further includes clock generator means for providing a corresponding plurality of clock signals and a plurality of conductors coupled between said clock generating means and said plurality of modules.

Abstract: A process and apparatus for removing the impurities from a gas stream produced from a landfill such that essentially pure carbon dioxide and methane is recovered. After the landfill gas is mechanically dewatered, the gas is filtered of particulate solids and aerosols and purified by removing sulfur compounds using zinc oxide columns, removing halogens using activated alumina columns, removing hydrocarbons using activated charcoal columns, and oxidizing remaining impurities using potassium permanganate impregnated activated alumina columns. Lastly the gas is incinerated in a boiler/incinerator combustion furnace to produce an exit stream containing essentially pure carbon dioxide and air, which is further treated in a conventional carbon dioxide treatment process.

Abstract: A battery powered paging and intercommunication system for application in a mine or other environment where it is necessary to conserve battery power comprises a plurality of transceivers electrically coupled to a common pair of signal lines. Each of the transceivers includes a push-to-talk switch for applying voice signals onto the lines as well as a push-to-page switch that amplifies received voice signals for reproduction through a loudspeaker. Each transceiver also includes dual tone multifrequency (DTMF) encoder and decoder circuitry for addressing a preselected transceiver on the lines for paging. A timer circuit within the transceiver limits the period of time the transceiver limits the period of time the transceiver is in the paging mode to reduce battery consumption. As a system check during paging, the called transceiver generates "beep-back" signals on the lines indicating to the calling transceiver that it is receiving paging signals.
