Patent SE-7905045-L (SE)
Inventor: JAKOBSEN K M
IPC: B29C59/04
Filed: 1979-06-11
Abstract: A tubular premoulding of a thermoplastic, suitable for subsequent shaping to produce containers by a rolling process. The material in a part of a tube is axially oriented as a result of reducing the wall thickness by applying an external pressure which causes the material to flow. The oriented material is moulded by a blow-moulding process into future mouth parts and parts of adjacent neck sections, preferably from two blank parts, joined to one another, of pre-mouldings, the blank parts in the transition between the two mouth parts being severed in order to form two separate blank parts, so that, after closing one end and, if necessary, reworking in order to obtain the requisite closing faces at the other end, the two blank parts each form a tubular pre-moulding.

Abstract: The invention in question describes a method for the production of Persian-blind slats. The slats have a forward cambered section and a punched aperture.As the material used for the slat is thin, 0.15 - 0.25 mm, and the track is, of necessity, placed only ca. 1.0 mm from the slat's edge, a problem arises where the slat jumps off when bent and /or punched.According to the invention, the critical area of the slat should be pressed so hard against the tool surface that no rupture occurs when bending or punching is carried out.<IMAGE>

Abstract: An assembly for monitoring torsional loading of a drive shaft comprises a magnetic-field generator juxtaposed to a cylindrical body of magnetostrictive material rigidly surrounding the shaft, the body being in the form of a thin foil attached to the shaft via a layer of magnetically insulating material, or a sleeve attached to the shaft by at least two spaced brackets or an outer layer of the shaft specially treated to have a homogeneous magnetic permeability in an unstressed state. A pick-up or magnetic-field sensor is juxtaposed to the body or sheath for detecting differential changes in the magnetic permeability thereof, the pick-up advantageously being connected to a demodulator which extracts a signal whose polarity is determined by the direction of loading of the shaft. In order to monitor the rotation rate of the shaft, the foil or sleeve is provided with a longitudinal slot and the demodulator is connected at its output to a low-pass filter and a high-pass filter which extract a torsion-dependent signal and a rotation-rate-dependent signal, respectively.

Abstract: The invention relates to a method for the manufacture of axle bracket halves. According to the invention, an axle bracket half is produced by extrusion moulding of an initial body, in which through changes in the cross- section of the shank region b the moment of resistance of the axle half can be increased with a saving of material. In the method of the invention, first a shank region b and a depression region c are formed from the ingot through hot-extrusion. The depression region c is then expanded and extruded into a rectangular shape and the shank region b formed into a square cross-section. In a final extrusion step the depression region c takes its finished form with local wall thickening. Openings for the drive- and cover side of the axle half can be punched out subsequently. <IMAGE>

Abstract: A magnetoelastic force transducer with temperature-compensated sensitivity is produced by equally exciting a measuring transducer and a reference transducer having cores of the same material and the same design and in good thermal contact. A spring loads the core of the reference transducer with a constant force. The output signal of the reference transducer is rectified in a phase-sensitive rectifier, the output signal of which is compared with a constant reference voltage. The difference signal resulting from this comparison controls the phase position of the control voltage of the rectifier in such a way that the output signal of the rectifier is brought into agreement with the reference voltage. The output signal of the measuring transducer is also rectified in a phase-sensitive rectifier, which is controlled by said control voltage and the output signal of which constitutes the temperature-compensated measured signal. The same phase-sensitive rectifier is preferably used for both signals by switching devices for the input and output connections of the rectifier.

Abstract: The manufacture of non-returnable packages for e.g. milk is frequently carried out by the conversion of web-shaped, laminated packing material to a tube, filling of the tube with milk and sealing and forming to filled packing containers of the desired, e.g. parallelepipedic, shape. During the forming, which is done by means of external forming devices, the contents are made use of as a holder-up for the forming devices pressed-on from the outside, so that the desired shape can be achieved without creasing or other deformations.The abovementioned forming principle works less well if the packing containers are not to be completely filled but have a certain air space, so-called head-space. The proportioning of the contents also becomes uncertain and the desired accuracy of volume cannot always be achieved. These difficulties are overcome if the contents are mixed prior to filling with gas, preferably sterile air, in appropriate proportions, so that the contents obtain a foam-like character, using a gas volume which is in a suitable proportion to the air space of the finished packing container. The invention relates to a method as well as to a manner of proportioning the contents in the manufacture of packing containers.
