Abstract: REVERSE FLOW COOLED DYNAMOELECTRIC MACHINES           WITH NOVEL COOLING SYSTEM                 ABSTRACT       A reverse flow cooled dynamoelectric machine is provided with duplex gas coolers disposed in a side-by-side relationship. The coolers are baffled such that a portion of the gas flowing through both coolers is channeled to both the end portion of the rotor and to the stator and the body portion of the rotor so that both areas may be effectively cooled under reduced load operating conditions in the event of the failure of one of the coolers. In a preferred embodiment of the invention, the baffle means comprises first and second U-shaped baffles disposed between the coolers and the inner wall of a removable dome. A planar baffle engaging adjacent free ends of the U-shaped baffles completes the baffle means. The baffle components are dimensioned to ensure satisfactory flow of cooling gas to the body portion of the rotor. Aligned stator and rotor baffles are provided to segregate inlet zones and outlet zones in the gap between the stator and the rotor to better ensure effective cooling of the body portion of the rotor.

Abstract: ABSTRACT OF THE DISCLOSURE            A toy musical vehicle can be constructed within a simulated vehicle body so as to utilize a single motor to simultaneously drive and operate a music producing mechanism and the vehicle.  The vehicle is driven by coupling the motor to wheels of the vehicle through the use of a conventional gearing arrangement. The music producing mechanism preferably includes a fan which supplies air under pressure to a wind chest coupled to the motor.  This wind chest is utilized in conjunction with valve actuators and valves which control the release of air so as to create sound in a conventional manner. The valve actuators are normally biased outwardly from the wind chest by the pressure of the air within the wind chest so that followers on these actuators are in a position to be engaged by any of a plurality of cams formed so as to extend from the surface of a rotary record member.  The periphery of such a record member is formed as a ring gear and mates with a spur gear driven by the motor through a drive train.  This record member is supported in a vertical slot in such a manner that it can be dropped in place so as to be rotated by the spur gear in order to bring the cams into contact with the followers so as to move the actuators and associated valve members to selectively control the flow of air from the wind chest.  The music producing mechanism is capable of and is considered desirable for independent utilization apart from such a vehicle.

Abstract: ABSTRACT OF THE DISCLOSURE            A device for coating, with a carbon material, the inner surface of a cathode ray tube having a neck and flared or cone end portion which is opened at its end remote from the neck along a free peripheral edge portion to which the front panel of the completed cathode ray tube is later secured.  The device includes a frame on which a turntable is rotatably mounted and supports, for rotation therewith, a seal assembly for selectively forming a seal on the inner surface of the flared portion of the cathode ray tube adjacent the free edge thereof.  The tube is supported on the turntable adjacent the seal assembly along its peripheral edge, and the assembly includes an expandable steel strip generally complementary to the internal configuration of the tube along which the seal is to be formed, so that upon expan-sion of the seal strip a tight seal is formed against the tube. The device includes a coating mechanism, as for example spray nozzles for coating the inner surface of the tube after the seal is formed, whereby the seal prevents the sealed or masked portion of the tube from being coated with the coating material.

Abstract: ABSTRACT OF THE DISCLOSURE       A machine for making mops, such as dish mops.  The machine is fed with a U-shaped wire, between the legs of which extends a bundle of flexible mop strands.  The machine twists the wire legs which lock the strands against the bight of the U-shape wire.  The machine comprises a holding plate provided with a hole through which the legs of the U-shape wire are inserted, with the strands abutting one face of the holding plate.  A power-actuated piston abuts the bight and presses the strands against the holding plate top prevent rotation of the bight relative to the plate.  The machine further includes a pair of pincers located on the other side of the plate and clamping the free ends of the U-shape wire.  The pincers are power-rotated for twisting the U-shape wire.  Opening and closing of the pincers are effected automatically.  The pincers can move towards the holding plate to allow for contraction of the U-shape wire as it is being twisted.  Two guide plates are pivoted on the guiding plate to align and guide the legs of the U-shape wire for proper insertion into the pincers.
