Patent DE-3107430-A1 (DE)
Title: Press stud
Inventor: WOLTERS KLAUS
IPC: A44B1/34
Filed: 1981-02-27
Abstract: The invention relates to a stud made of metal which can be hollow or solid and the shank end of which, pointing in the push-in direction towards a button-shaped plastic part, is designed in the shape of a mushroom. In order to make crease-free joining possible, it is proposed that the shank end of the stud, which is designed in a mushroom shape and points in the push-in direction, widens an opening of the plastic part as it penetrates and when the stud has reached its end position in the plastic part, the displaced material expands again and contracts firmly around the shank of the stud in such a manner that the stud and the plastic part are connected in a functionally reliable manner.

Title: Anchor-pile actuating means
Inventor: WERSCH HEINZ VAN DIPL ING
IPC: E02F9/06
Filed: 1982-01-27
Abstract: The invention relates to an anchor-pile actuating means for floating dredgers which essentially has two clamps (4, 11) which can be pressed hydraulically against the anchor pile (1) and can be released from the anchor pile (1) and of which one (4) is undisplaceably fixed to the hull and has the task of keeping the anchor pile (1) at a certain height, while the task of the other clamp (11), which is vertically displaceable relative to the hull, is to raise the anchor pile. In the raised position, the anchor pile (1) can be released by slackening both clamps (4, 11) and can bore into the bottom upon falling down. When the clamps (4, 11) are slackened, the floating dredger can move up and down relative to the fixed anchor pile (1). <IMAGE>

Title: Supercharged internal combustion engine for vehicles
Inventor: THAUER PETER ING GRAD
IPC: F02B39/12
Filed: 1982-02-18
Abstract: The invention relates to an internal combustion engine for vehicles, especially to a diesel internal combustion engine, which is equipped with an exhaust gas turbocharger and an additional, mechanically driven supercharger. In order to achieve a favourable torque and power output characteristic of the internal combustion engine, and to obviate the need for a charging pressure-related reduction of the full load fuel quantity, it is proposed that the supercharger (14) mechanically driven by the internal combustion engine (1) be automatically switched in by way of a controllable coupling (15) essentially only when the speed of the internal combustion engine lies below the efficient working range of the turbocharger (2) and the load of the internal combustion engine lies in the range close to full load. In addiiton the mechanical supercharger can also be switched in when the internal combustion engine is idling. <IMAGE>
Patent DE-3222959-A1 (DE)
Inventor: PROKSA FERDINAND DR ING
IPC: B29C44/46
Filed: 1982-06-19
Abstract: In the continuous production of block-foam from liquid reaction components, the danger of over-rolling exists in installations having low throughputs and in installations having high throughputs, which over-rolling results in faults in the finished block. These over-rolling phenomena are avoided by providing a conveyor belt in the mixture charging zone which belt transports on its conveying surface a foil which has trough-shaped indentations which can correspond to trough-shaped indentations in the conveying surface. The reaction mixture is portioned into the indentations of the foil. These portions are only spread out once the reaction mixture has reached the creamy phase.

Title: PLL oscillator circuit for generating frequencies belonging to a frequency pattern
Inventor: HANSEN JENS DIPL ING
IPC: H03L7/183
Filed: 1982-06-23
Abstract: A PLL oscillator circuit is proposed which has better static and dynamic characteristics than the known PLL oscillator circuits. In the PLL oscillator circuit, a mixing circuit (26) or a multiplication circuit (30), by means of which the first comparison frequency (fv1), which corresponds to the incremental frequency, is converted into a second higher comparison frequency (fv2), is provided between the output (21) of a frequency divider circuit (18) and a second input (22) of a phase comparison circuit (13). Due to the higher comparison frequency (fv2) and a higher reference frequency (fR2) corresponding to this higher comparison frequency, the cut-off frequency of a low-pass filter (14) belonging to the control loop of the PLL oscillator circuit is increased, which accelerates the correction and provides a possibility for modulating the reference frequency. <IMAGE>
