  • Device for twisting a packing wrapping
    Patent number: 4459792
    Abstract: Devices for twisting the extremities of a wrapping around for example a lollipop produced by high speed production machines often have long levers which are necessary to allow the stick of the lollipop to be supplied and discharged to and from the pairs of twisting claws. This results in high centrifugal forces on those levers. The invention abolishes this drawback by spacing the levers of the pair of claws in question outside the axis of rotation of the device. Further improvements can be reached by providing a counter mass.

  • Air pressure operated proximity sensor
    Patent number: 4458519
    Abstract: The disclosure relates to an air pressure sensor comprising a first air passage, a branch passage having an opening into the air passage, a sensor in the branch passage responsive to variation in air pressure in the opening and jet means for air flow through the first passage adjacent the opening to the branch passage to create an increased depression in static pressure as compared with the remainder of the air passage to enhance the response of the pressure sensor in the branch passage when air flow through the first passage occurs. The air passage terminates in a probe having an orifice to be opened and closed by the absence of and presence of a surface in contact with the probe so that the pressure sensor indicates whether or not the probe is in contact with the surface.

    Abstract: A pump consisting in a rotor (3) realized like a housing, placed in an outer housing (2), inside the rotor a cylindrical element (6) coaxially connected thereto by means of an elastic band (23) forming lobate chambers (13,14) between the rotor and the cylindrical element (6). Inside the cylindrical element (6) a solid cylindrical element (9) with a head (10) flared in the shape of a hexagon is rotating inserted, said cylindrical element (9) engaging with an hexagonal pin (11) fixed in an eccentric position on the closing part (12) of the pump. Thus an eccentric rotation of the cylindrical element (6) is caused and, consequently, the compression and the expansion of the chambers for the expulsion and the suction of the liquid (FIG. 1).

  • Alkali metal cells and batteries and the manufacture thereof
    Patent number: 4452871
    Abstract: In a sodium sulphur cell having, within a metal housing, a ceramic electrolyte tube separating the liquid alkali metal from the cathodic reactant, a current collector extends into the region inside the electrolyte tube and is electrically insulated from the electrolyte by an insulating element. The metal housing is sealed to the insulating element in a region around the current collector which region has a maximum cross-section substantially less than the maximum cross-section of the electrolyte tube and preferably lies wholly within the outer periphery of the electrolyte tube. The small seal areas with the constructions described give improved economy and reliability. The constructon has particular advantages with cells of short length.
