Title: Method and arrangement for the manufacture of containers
Inventor: SOERENSEN ERLING
IPC: B29L22/00
Filed: 1990-08-27
Granted: 1993-06-15
Abstract: The invention relates to a method and an arrangement for producing a container 10 with good dimensional stability that is filled with material 60. A preform 10a of crystalliseable plastic material and comprising a bottom part 11a and an opening part 13, the preform being filled with the filling material, is transformed into the container by means of a mechanical forming element 20. In the transformation of the bottom part, a mechanical forming element moves the bottom part against the opening part of the preform whilst simultaneously subjecting the material of the bottom part to temperature conditioning. The mechanical forming element bears against the bottom part long enough to give this a total degree of crystallinity of at least 15%. An arrangement according to the invention comprises a holder 50, which receives the preform 10a and in which the preform remains during the transformation of the bottom part, and a mechanical forming element 20 with a bearing surface 22, which by means of elements 26 acquires an increased temperature. The arrangement forms parts of equipment for filling the preform with material and the forming element is arranged for the said movement of the bottom part once the filling material has been delivered to the preform and for maintaining the bearing surface in a limit position of the said movement for a predetermined period of time. <IMAGE>

Abstract: Berry picker constructed with four hinges, which picker reduces the load on the back and the picking hand and gives cleaner berries, comprising four structural parts, a frame part 11 with a berry screen 10 and a picking container 15, a picking part 1 with a small space 3 for the berries, an extension shaft 13, at the end of which there is a thumb-operated control lever 17, and a handle 14. The picker is manoeuvred during the pushing movement with the aid of the position of the control lever 17, and during the pulling movement with the aid of the position of the handle 14. When the picking device is released from the shrub, it assumes the position in Fig. 2 in which the picking part 1 is inclined upwards and the berries fall from picking spikes 2 into the space intended for the berries. After the space has been filled, the berries are tipped via a screen 10 into the picking container. The construction of the berry picker additonally includes a protective base 4 which curves outwards 5 and outer picking spikes 8 which have been bent towards the outside of the picking device, and a construction with four hinges, in which the ratio of the distance between the hinges 9 and 12 in the picking part 1 and the hinges 16 and 18 in the handle 14 is approximately 2:3. <IMAGE>

Abstract: Spreading rolls are used in conjunction with, e.g., finishing equipment of paper mills to assure sufficient and constant cross-machine tension for the web running over guide rolls. Spreading is required due to web width variations caused by the coating, drying and calendering steps. A spreading roll comprises a curved shaft with its radius of curvature vector aligned in the machine direction and rotary driven roll segments mounted in bearings on the shaft. The roll segments are coupled to each other and they are driven about the shaft by a synchronous belt drive. The curvedness of the shaft complicates the design of a synchronous belt drive, and hence, the present invention concerns such a synchronous belt drive assembly for a web spreading roll that is free from angular nonalignment between the driving and the driven toothed pulley. The invention is based on mounting the driven toothed pulley in bearings on the bearing housing of the curved spreading roll shaft and then coupling the pulley with the outermost roll segment using a flexible coupling. <IMAGE>

Abstract: PURPOSE: To manufacture a contact member at low costs, and to enable attaching by forming a spring contact part so as to be forked, inserting the free end part of the leg part into a slit-shaped notch formed at an intermediate bottom part, and making the diameter of the notch a little larger than the diameter of a connecting pin. CONSTITUTION: A contact member 4 and a ground plate 3 are formed as a forked spring contact part 9 in the range of a connecting pin 7. The leg part of the spring contact part 9 is manufactured by cutting a plane contact member 4, and it is made rotatable within the plane face of the contact member 4. Moreover, the elastic edge part of the spring contact part 9 is inserted into a slit-shaped notch 10 formed at an intermediate bottom part 11 of a casing 2. This notch 10 is formed as a coherent vertical slit, and the diameter is made a little larger than the diameter of the contact pin 7. Thus, the contact pin 7 can be through guided in a centering hole 13 at the intermediate base part 11 while the side parts are guided between the both leg parts of the spring contact part 9.

Abstract: New heterocyclic compound - 3-morfolinobenzantrone (ABM) is synthesised which exhibits luminophor properties. The method of evaluation of cell-membrane structural and functional properties and evaluation of quality of immune system is elaborated by using ABM as fluorescent probe. Method provides registration of spectral parameters of ABM within suspension of immunocompetent cells - in suspension of lymphocytes. Correlation between ABM spectral parameters in lymphocyte suspension of healthy people and patients and index of blasttransformation of lymphocytes, anisotropic index, content of subpopulations of lymphocytes and their ratio within peripheral blood culture is determined. It is established that intensity of ABM fluorescence characterises immune system and permits to assess changes in some parameters of immune system and their mutual relations. Changes mentioned above are in straight correlation with clinical view of diseases. Method permits to obtain results in short time, volume of information obtained by this method is increased and it allows to avoid usage of expensive reagents and equipment.
