Patent DE-3632225-A1 (DE)
Inventor: JAERVENKYLAE JYRI
IPC: B29C48/13
Filed: 1986-09-23
Abstract: This invention relates to a method and an apparatus for the production of ribbed pipes. The apparatus comprises a core (8, 9, 10) which together with an extrusion sleeve (4) forms a nozzle (11) through which a plastic material is fed into a moulding space (12) defined between a mandrel (9) and chill moulds (1, 2) moveable with respect to the mandrel. Ribbed pipes produced by means of known apparatuses have, for various reasons, an uneven inner face, incomplete ribs or air closures and weak seams in the pipe walls and ribs. These disadvantages can be eliminated by such a dimensioning of the moulding space (12) of the apparatus and the grooves (13) of the chill moulds that the volume of a space defined between a plane (20) extending adjacent to the end face of the extrusion sleeve, a surface (16) of the mandrel, and a plane (17) comprising the envelope surface of the kernel (10) equals to the combined volume of the grooves (13) positioned within the area of the mandrel at each particular moment.

Patent DE-3711711-A1 (DE)
Title: Annular induction machine, which is liquid cooled
Inventor: BINDER MANFRED
IPC: H02K1/06
Filed: 1987-04-07
Abstract: In order to reduce the structural size of electrical machines, said machines are equipped with a large number of poles. In consequence, the cross-section of the winding is necessarily reduced, because the poles come very close together. The heat formation linked thereto in the winding can be coped with by cooling the winding directly. This can be done most easily by the number of turns per strand not being very high and the winding consisting of a thick-walled tube through which coolant flows. If the frequency of the AC voltage is very high, then good efficiency can be achieved. In this case, the machine rotor and stator assume the shape of a ring. The characterising features are accordingly,   - an annular machine, the plane of the effective pole surface being irrelevant. In the 100 kW range, for example, a pole width of only a few centimetres is required.   - Use of a coolant   - Induction machine   It is possible to dispense with extending the patent right to, for example, commutator machines or further functional types, because the rotor would have a salient winding and would be more costly. However, the following limitation applies: a generator is also an induction machine as a synchronous machine, because the current is produced by induction. A reluctance machine is also an induction machine, because starting is possible only by induction. A compensation machine makes possible, between an asynchronous generator and ...

Title: Method of displaying wrong spellings of words and texts on a display of a word processing office machine
Inventor: BEHRENS HERBERT
IPC: G06F17/27
Filed: 1987-12-24
Abstract: One of the most difficult problems of word processing is the production of correct texts to be stored or printed. The development of typewriters with electronic and/or magnetic memories has contributed to the solution of this problem to the extent that the operator of the machine only has to replace the wrong words, whereas the rest of the text is automatically and quickly printed or stored. Also, machines which compare each word which is entered via the keyboard with the content of a dictionary memory are already known. The operator is made aware of each wrongly written word by an acoustic signal. The object of the invention is to create a method of displaying wrong spellings of words and texts on a display of a word processing office machine, so that the operator can correct a wrong word simply, quickly and reliably. The way this object is achieved is that the suggested correction or the explanation of each wrongly reproduced word is automatically displayed in a line directly below it, in the following line, and that if the suggested correction is accepted by activating a first special key, the correction is displayed on the screen. If the suggested correction is not accepted, by activating a second special key, the ... Original abstract incomplete. <IMAGE>

Title: Structure-borne sound-damping composite system
Inventor: MEYER FRIEDRICH DIPL ING
IPC: B32B7/022
Filed: 1988-06-16
Abstract: Composite systems for damping flexural waves in walls comprise an intermediate layer applied to the wall and subjected to shearing stress and a stretch-resistant covering layer, which in the case of symmetrical composite systems is of the same material and the same thickness as the wall. To accomplish the properties of a symmetrical composite system without weight problems arising, according to the invention the symmetry is achieved by the covering layer consisting of a shear-resistant polymer compound with a thin final layer and being dimensioned such that its flexural resistance is the same as that of the wall. By adding lightweight substances into the polymer compound, the relative density of the composite system is made equal to or less than water. It can be used particularly advantageously for structure-borne sound damping on submarines.
