Abstract: The invention relates to a stretch rod for the form-and-fill head of a machine for forming and filling of containers produced from preforms. The object of the invention is to devise a stretch rod of this type which can be cleaned and/or disinfected without being disassembled and without any other intervention. According to the invention, the object is achieved by a stretch rod (5) for the form-and-fill head (3) of a machine for forming and filling (molding and filling) of containers produced from preforms (2), which rod comprises a drive unit for axially moving said stretch rod (5). At least the part (6) of the drive unit which is connected to the stretch rod (5) is arranged in a drive chamber (11) which is sealed off from the regions of the form-and-fill head (3) which come into contact with the filling material (the material with which the container is being filled). The inventive stretch rod is characterized in that the sealing action is achieved by a seal (12) which surrounds the stretch rod (5).

Abstract: The invention relates to an arrangement 1 for feeding contents into a container being formed from a preform 2 in a mold 3, in a machine for simultaneously molding and filling containers made from preforms, wherein the arrangement defines, by the way of its wall 7, a flow path between a contents-supply line 4 and the mouth opening 6 of the container. The arrangement 1 is characterized in that it has a sealing termination both in relation to the contents-supply line 4 and in relation to the preform 2.

Abstract: A heating apparatus that includes a plurality of heating devices for temperature conditioning of preforms made of a thermoplastic material to a temperature and temperature distribution suitable for blow molding and transport and handling means for transporting and handling the preforms through the heating apparatus along a transport path. The transport and handling means are implemented as a transport chain guided on a revolving chain path that has a plurality of chain-link-type transport means connected thereto. Along a heating section that is part of the transport path, the plurality of heating devices are stationarily arranged one after another in a transport direction. On at least one side facing the heating devices, counter reflectors are provided, which together with the heating devices form a tunnel-like heating area through which the preforms are transported for heating. At least one counter reflector travels along with the preform through the heating section.

Abstract: A method for temperature conditioning thermoplastic preforms for blow molding. The preforms are guided along a chain path in a transport direction by a plurality of transport and handling means through a heating apparatus. In a heating section, the plurality of heating devices are arranged one after another in the transport direction. On at least one side opposite the heating devices, counter-reflectors are provided, which together with heating devices, form a tunnel-like heating area through which the preforms are transported. In an area of the heating section, a concurrently moving counter-reflector is assigned to each perform or each transport and handling means. The counter-reflectors are guided on a circulating reflector path separate from the chain path, which in the area of the heating section runs parallel to the chain path and in at least one area outside the heating section takes a path route deviating from the chain path.

Abstract: The invention is directed to a device for the determination of the change in the mechanical magnitudes during muscular contraction and for the correlation with the change in the electrical magnitudes of nerve and muscle during muscular contraction. The body part with joint, which is to be investigated, is attached to a bolster (2) which rotates sagittally and is supported by means of axles (7, 8) on a line coinciding with the axis of rotation of the joint. An electromagnetically controlled functional coupling (10) and an electric motor (9) are connected to the axle (7) so as to be controllable, and horizontally extending flexure beams (27, 28), with stress measurement strips (29, 30), are fastened at the longitudinal sides of the electric motor (9). A potentiometer (11) and a torque measurement strip (31) are arranged on the axle (8).
