  • Patent number: 4921021
    Abstract: A filler pipe for a packing machine for consecutively filling a traveling and continuous series of connected packing container blanks, with a liquid product such as yogurt, and a separate jam product, without mixing the two types of product. This filler pipe is used in conjunction with blanks formed of two joined webs and provides sealing of the filled packing containers. The invention utilizes a nozzle with multiple filling paths each of which passes product to at least one of the packing container blanks. The nozzle receives the liquid product from a flat shaped larger delivery pipe, and the jam product from a smaller delivery pipe parallel to the larger pipe. The smaller pipe, which may be located inside or on the outer wall of the large pipe, is placed at a predetermined distance above the junction of the larger delivery pipe and the nozzle. In this way each container is first filled with its share of jam product and then with the liquid (yogurt) product with no mixing of the two products.

  • Patent number: 4537553
    Abstract: A silo or the like for storing pulverulent, granular or lumpy material has a wall which encloses the silo storage space, a roof whose pitch substantially corresponds to the angle of repose of the material, an inlet opening in the silo roof, an outlet opening in the silo floor, and a screw conveyor suspended from a beam rotatable about the axis of the silo. The beam is inclined downwardly from the inlet opening of the silo and extends substantially parallel to the roof pitch, and the conveyor is suspended from the beam by means of wires which are adjustable independently of each other with respect to their length. The conveyor can thus be anchored close and parallel to the supporting beam when material is fed into the silo, and be disposed at a suitable angle, preferably inclined downwardly toward the center of the silo, when material is discharged from the silo.

  • Patent number: 4231613
    Abstract: A seat cushion for children, placed on the seat bottom of a vehicle seat to provide an elevated sitting position. Uniformly constructed guides for a hip belt, arranged on two opposite sides of the cushion, engage the belt to prevent it from sliding upwards when the cushion is positioned for use and the belt is coupled. Each guide includes a first portion extending forwards in the direction of the vehicle and defining a forwardly opening slot through which one part of the hip belt passes, and a second portion extending laterally outside the slot and forming a stop for a part of the belt located outside the slot to prevent the second part from moving upwards.

  • Patent number: 4184159
    Abstract: The disclosure relates to a method for silage temperature control in a silo. Measurement transmitters are placed at points where it is desirable to check the temperature of the silage located in the silo. These measurement transmitters are activated, on temperature control, by means of an activation transmitter with an antenna. On activation, the measurement transmitters transmit a signal which is related to the ambient temperature, this signal being received by a receiver. If a measurement transmitter indicates a temperature deviating from a predetermined norm, it is localized by direction finding.
