摘要:
A streamlined monolithic internal combustion engine muffler is disclosed, which muffler deadens the noise generated during combustion and diffuses the gaseous composition exhausted into the atmosphere.

Apparatus for use in cathode ray tubes and particularly in multi-gun color television picture tubes and like devices to enable substituting for the active cathodes and associated parts other standby cathodes and parts which will restore the tube to full emissive power and substantially double the life of the tube, said apparatus including a multicathode assembly mounted inside the neck portion of the envelope of the picture tube, said assembly having a plurality of active and standby cathodes and associated heater elements mounted thereon, and means including magnetic means for moving said assembly between alternate positions inside the tube envelope whereby selected ones of the cathodes and their associated heater elements are in operative positions and others are not. The present apparatus enables replacement of the active cathodes without requiring any modification of the tube envelope itself, without requiring removal of the tube from the set in which it is installed, and with little or no modification or adjustment of the set to accommodate the change.
摘要:
A water distribution apparatus employs a self-positioning water flow actuated rotor for serially channeling water flow into each of a plurality of outlet conduits from a common source of water under pressure. The rotor, housed within an encapsulating cavity, includes a hollow hub closed at an end and having the other end in fluid communication with the source of water under pressure. A plurality of jets eject water from within the hub intermediate a pair of hub mounted discs and provide motive power for rotating the rotor. Opposed apertures in the discs provide fluid communication between the jets and serially with a selected pair of opposed outlets connected with one of the outlet conduits; the rotational positioning of the rotor corresponding with a pair of outlets is regulated by a timed solenoid. Axial centering of the rotor within the cavity intermediate the opposed pairs of outlets is provided by the water pressure acting on the closed end of the hub in conjunction with bearing members defining the limits of the hub's axial movement.
