Abstract: A pump assembly for use in fire fighting service is constructed of a single stage main pump and a two stage booster pump connected in series with the discharge of the main pump being connected to a first high flow rate fire fighting application and to the inlet of the booster pump and the discharge of the booster pump being connected to a second low flow high pressure fire fighting application. The impellers for both the main pump and the booster pump are mounted on a common rotating shaft so as to be driven thereby. A flow restriction and conduit means is provided to reduce the pressure on the booster pump seal. A by-pass conduit is arranged to conduct flow from the discharge of the booster pump back to the inlet of the main pump so that whenever the main pump is operated there will be flow through the booster pump to prevent overheating thereof.

Abstract: An abrasive grinding machine wherein the periphery of a rotatable grinding wheel always is returned to, and during grinding maintained at, a constant and precise workpiece grinding position irrespective of the reduction of the diameter of the wheel from wear and/or dressing. The grinding wheel is mounted rotatably on the distal end of a rockable pivot arm which, during grinding, is actuated periodically to retract the wheel from and return it to workpiece grinding position. A control mechanism, constituted by a fixed stop on the pivot arm, a moveable cam for the stop and a programmable drive motor for the cam, is operative periodically, in harmony with the reciprocable movement of the pivot arm, to adjust the cam relative to the stop to permit controlled, incremental increases in the distance over which the grinding wheel is periodically retracted from and returned to workpiece grinding position. The invention finds particular use in conjunction with dressing tools or wheels for a grinding machine.

Abstract: A quick-disconnect cam locking safety coupling has a hollow male plug having an external peripheral groove. The plug is received in a socket. The socket has a pair of opposed openings opposite the peripheral groove. A gasket seals between the male plug and the socket. A pair of cam members each has a lever lying adjacent the socket and a cam portion passing through one of said side openings and engaging the peripheral groove. Each cam member is pivotally connected to the socket for outward movement of the levers away from the socket to disengage the cam portions from the peripheral groove. Each cam member is locked in the groove engaging position by a removable wire pin engaged by at least one lug on the socket and adapted to limit the outward movement of the cam member lever.

Abstract: The present invention is concerned with manufacturing board from a fluid evolutive product, such as a plaster and water mixture. The process comprises pouring upon a conveyor a fluid evolutive product, such as a plaster and water mixture, contained in storage above the conveyor, through a transverse, parallel slit into which the product is introduced in continuous process through a number of nozzles which discharge into the storage product mass. A reinforcement may be introduced into the poured product. The invention offers as well mechanism for the implementation of the process and products manufactured by the process. Typically the invention is applied to plaster board manufacturing.

Abstract: The method and apparatus of the invention simultaneously induces the same variable frequency mechanical vibrations in a test part and a standard. The vibrations of the two are converted to signals which are either displayed for comparison purposes or automatically analyzed for differences. Advantageously, the signals are electrical signals providing spectra which are analyzed for differences in amplitudes produced by the signals. Where the parts are separately supported, they are held with substantially the same force and are maintained against the vibration inducing mechanism with the same force. Where accelerometers are used, they are held with substantially the same force against the vibrating parts.
