Patent DE-3906570-A1 (DE)
Inventor: THANISCH KLAUS
IPC: B65D47/08
Filed: 1989-03-02
Abstract: A one-piece plastic closure comprises a lower part (1), a lid (3) and a snap hinge (6). In order to connect the lower part directly to the lid (3), the snap hinge comprises one or more film hinges (8) aligned in the main axis of rotation (10). The snap hinge comprises at least one elastic element (14) which, in the closed position, does not project beyond the external profile of the adjacent sections of the lower part and of the lid, but is as flush as possible with them. The elastic element is connected to the lid and the lower part by linear articulations (16) parallel to the main axis of rotation, at a certain distance from the latter. At least one film hinge is located with the necessary play on the outer faces of the lower part and of the lid. The sections of the lower part and of the lid immediately adjacent to the film hinge have marginal surfaces (22, 24) inclined to their outer face (bevelled edges) which in the closed position are adjacent and in the open position swivel apart. In the closed position of such a closure, the film hinges do not project outward. Instead, they are located in the outer wall of the lower part and in one edge or outer wall of the lid. The lid and the lower part can also be connected by a small strip (30) or several aligned small strips. In this case, the small strip is fully retracted inside the outer profile when the closure is closed.

Filed: 1989-11-06
Abstract: A flattening and haul-off apparatus for a plastic tubular film blow-moulded from a fixed film blowing head has flattening plates and pinch rolls which can be swivelled reversibly about the axis of the fed-in film tube and is provided with a downstream fixed winding or further-processing apparatus and with a radially outer deflection roll, parallel to the pinch rolls and reversing with them, as well as a radially inner reversing rod, by means of which the tubular film is guided between the pinch rolls and the winding or further-processing apparatus or a fixed deflection roll feeding the tubular film to the latter and which lie in planes parallel to the swivelling plane of the pinch rolls. The distance of the deflection roll from the pivoting axis is greater in every possible swivelling position than the distance of the part wrapped around by the film of the reversing rod swivel-mounted close to the swivelling axis from the said axis. The swivelling movement of the reversing rod is only half as great as that of the deflection roll. To be able to increase the diameter of the reversing rod as much as desired, without thereby hindering or hampering the drawing-in of the flattened tubular film when setting up the apparatus, the pinch rolls (30) with the deflection roll (28, 29) on the one hand and the reversing rod (16) on the other hand are mounted on shafts or spindles with mutually aligned centre lines in a supporting frame (5) or the like. The supporting frame (5) has between the mountings a recess in the region of the reversing-rod swivelling plane, which passes through the centre line.

Patent DE-4011313-A1 (DE)
Inventor: SCHILLER JOERG DR
IPC: G01N3/40
Filed: 1990-04-07
Abstract: In the process described for measuring the hardness or elastic properties under load of materials, using the ultrasonic contact impedance method, the change df in the frequency f of a resonator is measured and the hardness value HV (or modulus of elasticity E) calculated from the measured change in frequency by means of a conversion formula, using known values for the modulus of elasticity E (or the hardness HV) and the transverse contraction ratio  mu  of the sample. The frequency change df is measured using at least two different test forces, and the frequency changes df thus measured are each inserted in a conversion formula of the form HV = G(df, a, Ro, b) in which a is a sample independent system constant, Ro is the reactance of the sample and b is a term which includes the modulus of elasticity E and the transverse contraction ratio  mu . This gives a number of linear equations corresponding to the number of different test forces used, from which (a) either the hardness value HV can be calculated if term b is known or the term b can be calculated if the hardness value HV is known, independently of the reactance Ro, or (b) the reactance Ro can be calculated if the hardness value HV and the term b are known.

Title: Needling machine for web fibre interlocking - has speed differential mechanism for deeper penetration of material and increased angular velocity in no=load period
IPC: D04H18/00
Filed: 1990-05-10
Abstract: Needling machine for the mechanical interlocking of fibres in a web, has an element included to reduce the speed of the needle bar at the time of needle penetration. The drive is a constant speed, thus the non-productive needle lift is faster. The longer load time allows greater needle penetration. Pref. speed of prodn. is affected more by the material needled, than by the mechanism. If the drive speed is constant, more efficiency will be obtd. if the angular velocity during the period of needle penetration by the bar, is slower than during the top inactive period. ADVANTAGE - For the same prodn. speed, the needling can be faster, and intensified.
