  • Patent number: 10906069
    Abstract: The present invention relates to a packaging device and sorting system (82) for directional packaging of products (P), such as vegetables and fruit, and a method therefore. The packaging device according to the invention comprises: —a sensor system (54) configured to detect a collection of suitable pick-up points; —at least one directing unit (16) configured to direct a product and provided with at least one degree of freedom for rotation of the product around a substantially horizontal rotation axis; and —a manipulator (28) comprising: —a pick-up element (44); and —a moving device (30) comprising at least four degrees of freedom for translation of the product and rotation around a substantially horizontal axis, wherein a rotation of the product around a substantially vertical rotation axis is possibly by means of providing the moving device and/or directing unit with an additional degree of freedom.

  • Patent number: 5495238
    Abstract: An electro-mechanical induction watt-hour meter has a rotatable disc and a projection on the base directed into the meter terminating in proximity of the rotatable disc. The projection is part of a pulse initiator system where a pulse signal is transmitted through a selected area of the base that is transparent to the signal. A signal is generated externally of the meter and chopped by rotation of the disc providing a pulse signal that passes through the base of the meter to a receptor external to the meter. The signal generator and the pulse signal receptor are both located in the enclosure defined by the base of the meter and the receptacle socket for the meter. The generated signal is disclosed as a light beam that, by way of light guides on the meter base, is directed to one side of the rotating disc and is directed by one light guide and to the other side of the disc where another light guide returns the chopped or pulsed signal to the receptor.

  • Patent number: 5364290
    Abstract: A base for an electric utility watt-hour meter made from a polycarbonate material preferably reinforced with glass fiber and ultraviolet light stabilized. The molded base receives current terminals that have outwardly directed lugs engaging one face of the base and there are locking arms on the other side of the base resiliently biased against the lug to engage a locking formation thereon. The base has a knife-edge rib extending about its periphery to sealingly engage a front edge face of a cup shaped transparent cover for the meter. A metal ring joins the cover to the base the metal ring being a band with a first series of lugs struck out and directed inwardly to engage the flange on the cover and a second group of tabs struck outwardly and bent inwardly to engage the bayonet ramp surfaces on the base.
