Title: Regular dodecahedron shaped bullet - is used in gun with round bore and has flat circular faces with conical recesses
Inventor: FILBRICH REINHOLD
IPC: F42B7/10
Filed: 1979-11-09
Abstract: The bullet is designed for use in a gun-barrel with a round bore, e.g. a shotgun. The bullet is made in the form of a regular polygon. Recesses (4) are formed in some or all of the polygon surfaces (2), and can be conical and rounded at the bottom. The design avoids the risk of the barrel bursting if the bore is tapered, as the walls of the recesses or edges of the polygon are able to deform. The bullet has an approx. circular outline, the polygon surfaces being circular in shape. The five vertices of the regular pentagonal faces of the regular dodecahedron are replaced by little spherical triangles (3).

Title: Paper machine for producing sanitary papers
Inventor: RUECK KARL
IPC: D21F11/14
Filed: 1981-03-27
Abstract: A paper machine for producing sanitary papers has a twin-wire former and a headbox. At the outlet opening thereof, a first wire belt initially forms a pre-drainage zone. Subsequently, it runs together with a second wire belt over a preferably solid forming cylinder. In order to provide the paper produced on this paper machine with a high specific volume in spite of the use of waste paper as raw material, the first wire belt runs, at the outlet opening of the headbox, over a drainage roll, whose roll body has grooves extending in the peripheral direction, and, between these, similar webs to which a water-permeable fabric is fixed. This makes it possible to omit a flow dryer in the drying part of the paper machine. Preferably, a contact drying cylinder is the only thermal drying device.

Title: Method for recipe-faithful batchwise manufacture of bituminous mixed material
Inventor: NIGGEMANN HELMUT DIPL ING
IPC: E01C19/10
Filed: 1981-04-18
Abstract: The invention starts from a method for recipe-faithful batchwise manufacture of bituminous mixed material from individual components in a preparation installation equipped with storage containers and weighing devices. Firstly, rough weighing of each individual component is carried out, the actual weights of the individual components being determined, and subsequently a fine weighing of at least one component is added, in order to keep the desired weights of the components of the mixed material according to the recipe within the respectively admissible tolerance range. In this case, it is a matter of making possible a recipe-faithful batchwise manufacture of bituminous mixed material within the admissible tolerances in a short time, without the capacity of the manufacturing installation having to be reduced significantly. To this end, the component, the actual weight of which exceeds its desired weight the most after the rough weighing, is established and the tolerance range is fixed with its upper limit corresponding to this maximum overweight. After checking the remaining actual weights against the thus fixed tolerance range (21'), only those components of which the actual weights lie outside the tolerance range are additionally fine-weighed. Thus, only those components which lie outside the tolerance range are selectively followed up. <IMAGE>

Patent DE-3119972-A1 (DE)
Title: Overload protection device
Inventor: RODIG BERND
IPC: F02P3/055
Filed: 1981-05-20
Abstract: An overload protection device is proposed for a circuit arrangement having a high blocking-capability power transistor (T1), connected in series with a load (RL), and having a control circuit which drives the power transistor (T1). The overload protection device protects the high blocking-capability power transistor against unacceptably high power loss, and the control circuit against unacceptable overvoltages. Between the two operating current lines (10, 11) of the control circuit, the overload protection device contains the series circuit consisting of at least one active element (A1; A2), which blocks below a threshold voltage, and of a transistor (T5), connected as a diode. The transistor (T5), connected as a diode, together with a second transistor (T4) of the same conductance type, forms a current balancing device (T4, T5) whose current transfer can be adjusted by introducing an emitter resistor (R8) belonging to the second transistor (T4). The output current of this current balancing device (T4, T5) can be converted with the aid of a collector resistor (R5) of the second transistor (T4) into a voltage (UTR), which can be evaluated and is used as the input voltage of a Schmitt trigger (ST). The Schmitt trigger (ST) drives a control transistor (T3) which switches off the power transistor (T1) to be protected when the maximum permissible operating voltage is exceeded. <IMAGE>
