  • Patent number: 4146900
    Abstract: A printing system is disclosed wherein ink is emitted from a nozzle as entrained in a jet of air. The ink is introduced onto an ink wall from an ink passageway and a fluid passageway has an outlet directing air at an angle onto this ink wall to cause ink to flow along the wall and form into ligaments and eventually part from that wall as droplets. The droplets part from the ink wall primarily at a tip wall which diverges out of the air stream. In a preferred embodiment there are two such ink walls and the two flows of ink droplets converge to form a single stream. A printing head contains a plurality such as seven such nozzles in a row and then relative movement of the printing head and the printing surface together with controlled pulses of the emitted ink will cause alphanumeric characters to be imprinted on the printing surface.

  • Patent number: 4139790
    Abstract: A permanent magnet rotor for a permanent magnet synchronous-run induction-state motor is disclosed. The rotor has Rare Earth magnets disposed in apertures in unitary laminations and parallel to a tangent to the shaft. The magnets are magnetized outwardly so that the direct flux of the magnets is additive to the direct axis flux of the stator at no load. The rotor has a squirrel cage winding and the ends of each magnet aperture are in communication through a flux barrier space to the inner end of an adjacent conductor bar aperture of the squirrel cage winding. The unitary laminations each have an even plurality of radially directed reinforcing ribs disposed along the magnetic neutral axes. The flux barriers are wide relative to the circumferential width of the reinforcing ribs for a minimum of circumferential leakage flux. The leakage flux from one magnet radially through a rib is in opposition to the leakage flux through that rib from the adjacent magnet for substantially zero net leakage flux therein.

  • Patent number: 4136582
    Abstract: The present application discloses structure which produces area contact in place of point or line contact between a cylindrical shaft and a cylindrical bore. When the area of contact is increased, the unit pressure is reduced which results in less wear and longer life. The combination of the present invention includes a shaft having an external surface and a member in the nature of a gear or the like which has a bore surrounding the shaft and which bore includes an internal surface. The present invention involves the situation wherein one of the shaft and member is fixed and the other of the shaft and member is rotatable. The improvement of the present invention involves the situation wherein the surface of the rotatable one of the two above mentioned members is provided with a first cooperating surface portion which has a constant radius and which extends through an angle 360.degree..

  • Patent number: 4135569
    Abstract: A molding machine for use with quick setting and cold setting sticky mold material, a mixture of sand and self-setting adhesive, is provided with a device to clean out the machine during each cycle and after the blow operation is completed. The sand and adhesive is mixed with the catalyst to a condition so that it will set up in a matter of seconds, e.g. ten to sixty seconds, and as it is mixed, a predetermined quantity is immediately deposited in a magazine. The magazine is closed by a valve and air pressure is applied to blow the sticky mold mixture from the magazine through a blow head into a mold cavity wherein it immediately starts to set. A diverter is provided with a diverter passage just outboard of the blow apertures of the mold box and this diverter passage is next enabled and air pressure is again applied through the magazine and blow head to blow any small amount of excess sticky mold mixture out the diverter passage into a receptacle.

  • Patent number: 4132208
    Abstract: An ignition system for an internal combustion engine wherein ignition timing is retarded when the engine speed exceeds a predetermined value. The ignition angle retardation is effected by an angle retarding circuit for by-passing at least part of an AC ignition signal. The angle retarding circuit is actuated responsive to an output of a phase-advanced signal generating circuit for generating an AC signal in advance in phase of the ignition signal. The utilization of the phase-advanced signal generating circuit enables the ignition angle to be varied over a wide angle.

  • Patent number: 4122597
    Abstract: A tool storage mechanism is disclosed wherein a tool storage magazine is mounted by a pivotal connection to a vertically movable tool slide. The tool slide also carries a horizontally movable tool slide carrying a rotatable tool for operating on a workpiece which moves in the third mutually perpendicular direction. The carried tool slide retracts to a tool change position whereat a tool changer will interchange a tool in the tool spindle with one in a socket of the tool storage magazine. Accordingly, the tool storage magazine moves up and down vertically with the first tool slide but has its own second drive means separate from the first drive means of the first slide. This second drive means is close to the nominal center of mass of the tool storage magazine but this center of mass changes as the magazine moves to present selected tools to the tool changer.

  • Patent number: 4119076
    Abstract: An ignition system for an internal combustion engine having an AC generator compriss an ignition coil energized by an output from the generator. At an angle in advance of ignition timing, a first thyristor connected across the generator output terminals is turned on to permit a short-circuit current therethrough. A capacitor is charged by an output from the generator, and is discharged through a second thyristor which is triggeed at the ignition angle. The discharge current is reversely applied to the first thyristor and the first thyristor is turned off. Interruption of the short-circuit current through the first thyristor leads to a large current through the primary of the ignition coil, causing a high voltage in the secondary with resultant spark in the ignition plug.

  • Patent number: 4119896
    Abstract: A sequencing control circuit is provided for a door operator motor which is connected to open and close a garage door as controlled by signals from manual switches and load switches. The sequencing control circuit includes time delay means with a first time delay period in the order of six to eight seconds. This permits a person to hold a push button switch closed for about six to eight seconds so that a slab door may be opened against a snow drift which otherwise would have so much torque requirement on the motor that an overload switch would stop the motor. Enabling means is provided to enable the motor during this time period yet to disable the constant signal from the push button for periods longer than this time delay period so that the door operator motor then is responsive to signals from the load switches.The sequencing control circuit also includes a latch circuit having an output in a feed back loop to maintain the latch circuit latched upon a momentary input control signal.
