  • Method and apparatus for high speed transfer and insertion of electrical components
    Patent number: 4507862
    Abstract: Under direction of a machine controller, conveyor mounted clips sequentially present electrical components to an unload station while holding the components by their leads, and the components are centered relative to a loader assembly by lateral displacement of the clip relative to a loader axis. Thereafter, a loader assembly clamps the leads of the component and transfers the component to a load station and into engagement with the jaws of an insertion head. The loader assembly is then actuated to drive the leads of the component into the jaws of the insertion head for subsequent insertion of the leads into holes of a printed circuit board. The component, gripped in the jaws of the insert head, is oriented about an insert axis, according to a controller and prior to insertion.

  • Stabilizing device for gyroscope effect apparatus such as a space craft or vehicle, especially with a view to damping the nutation motion
    Patent number: 4504033
    Abstract: The nutation damper comprises a closed flow path for a dense liquid, which may be a propellent and a pump for setting the liquid in periodic motion, thereby to dissipate or generate rotational energy controlled by a detector sensitive to a parameter relating to the nutation angle, according to the law of conservation of angular momentum. The principal application of the device is to the nutation damping of spinning spacecraft, in which the ratio between the moment of inertia about the spin axis and the lateral moment inertia is greater or less than 1.

  • Indexed feed of electronic component supply tubes
    Patent number: 4500246
    Abstract: Constant supply of electronic components to a processing station is effected by a reservoir and component supply tubes indexed to sequentially unload into the reservoir automatically, as the need arises. Plural component supply tubes are mounted in a cartridge assembly at each station of a multistation processing machine. Upon command of a controller and in response to a low part sensor of a reservoir at each station, the cartridge is indexed to the next tube in order to unload the components of that tube into the reservoir. Each station includes a separate indexing mechanism for each respective cartridge, and a carriage is translated to a position adjacent the indexing mechanism of each station, upon command, in order to effect such indexing.
