Patent DE-3210339-A1 (DE)
Title: Device for cleaning containers, vessels or the like using a pressurised jet
Inventor: WEINHOLD KARL DIPL ING
IPC: B05B13/06
Filed: 1982-03-20
Abstract: The invention relates to a device for cleaning containers, vessels or the like using a pressurised jet. Generally, warm water, hot water or saturated steam are used to produce the pressurised jet. This leads to extremely high stresses in many cases, in particular in the region of the bearing between the fixed and the rotatable nozzle part of the device. The invention aims at remedying this by proposing that the rotatable nozzle part surrounds in a pot-like manner, forming an annular space, a fixed nozzle part which is coaxial with respect to the connecting piece, and that the rotatable nozzle part is supported with respect to the fixed nozzle part by means of an axial bearing located in the annular space. By virtue of this design, the nozzle parts which can be rotated with respect to one another have a relatively large degree of play with respect to one another whilst all the stresses which occur in the region of the axial bearing can be absorbed without difficulties. By virtue of the pot-shaped design of the rotatable nozzle part, the outlet channels can be arranged in such a way that even inner regions of a container which are difficult to gain access to can be cleaned satisfactorily.

Title: Loudspeaker combination
Inventor: WENDT FRIEDRICH-KARL
IPC: H04N5/60
Filed: 1982-04-14
Abstract: A loudspeaker combination with at least two loudspeaker systems, for example a tweeter and a woofer, which is suitable for installation in close proximity to the picture tube of a colour television, should, with its resulting stray field, have no interfering effect on the electron beams and thus no undesirably severe effect on the screen scanning. The present invention proposes selecting reverse polarity for the magnets of two loudspeakers and reducing only the resulting stray field of the stronger magnet to an acceptable value with a simple and inexpensive screen.

Patent DE-3219491-A1 (DE)
Title: Arrangement for pulse generation for high-resolution measurement of the speed and position of rotating machine parts
Inventor: BUCHMUELLER REINO DR DIPL ING
IPC: G01P3/488
Filed: 1982-05-25
Abstract: Magnetic moving-coil transducers with Wiegand modules have the advantage that no auxiliary energy is required. However, in known moving-coil transducers with Wiegand modules the highest pulse repetition frequency that can be achieved is limited to approximately 10 kHz. This is caused by the remagnetisation processes in the Wiegand wire, which require a certain time. The solution according to the invention circumvents this difficulty by constructing the Wiegand module (5) from a plurality of individual elements (7) arranged next to one another in the direction of rotation of the impeller (1), and designing the teeth (6.1, 6.2) of the impeller (1) to be so wide that they cover a plurality of individual elements (7) of the module (5). The elements of the module are connected in series or parallel. After a tooth has passed through the transducer, the module transmits a chain of pulses. The maximum pulse repetition frequency can be increased with the aid of these measures by a factor of approximately 10 with respect to the known solution. <IMAGE>

Patent DE-3303418-A1 (DE)
Title: Speech aid for stutterers
Inventor: KUEPPERS BERT PROF DR ING
IPC: A61F5/58
Filed: 1983-02-02
Abstract: Appliance which allows stutterers to engage in error-free dialogue by supplying to the stutterer's ear a so-called masking noise which is able to suppress the faulty coupling between the speech centre and the organ of speech. The masking noise consists of a harmonic-containing signal which approximately corresponds to the fundamental frequency of the stutterer's voice and is periodically changed by approximately half an octave. This noise is supplied to the stutterer's ear via headphones and is triggered by him as soon as he starts to speak. The triggering of the masking noise takes place via a microphone which is attached in front of the stutterer's mouth and which utilises the high sound level produced by the stutterer in his vicinity, the directional effect of the microphone and the spectral dispersion for recognising sound from the stutterer and foreign sound. Since the stutterer on exposure to a high level of masking noise raises his own speech level, a level control is provided and emits a selectively perceptible signal to the stutterer when a speech level is exceeded. <IMAGE>
Patent DE-3308508-A1 (DE)
Title: Spark plug for internal-combustion engines
Inventor: STEINKE LEO
IPC: H01T13/04
Filed: 1983-03-10
Abstract: A spark plug is proposed which is used for the ignition of fuel-vapour/air mixtures in internal-combustion engines. The spark plug is of a construction which is known in principle but is provided, according to the invention, with an advantageous securing device for the connecting nut, which is screwed to the connecting piece on the connecting side, and has a specific outline profile (SAE nut). A truncated-conical section, which is tapered on the connecting side and preferably has an acute angle, is integrally formed on the connecting side of the connecting bolt flange which rests on the electrical insulating body of the spark plug. The correspondingly designed connecting nut is clamped by means of this truncated-conical section of the connecting bolt during screwing on; raised or depressed means, which are inegrally formed on the truncated-conical section of the connecting bolt and/or on the corresponding region of the connecting nut (which is used as a stop) and are preferably of sawtooth-like configuration, still support the clamping of the connecting nut and connecting bolt. The connecting nut according to the invention can be screwed onto the spark plug connecting bolt using the tool which is carried on board the vehicle and is required anyway for screwing the connecting nut on, and the screw securing device is hence brought into effect. <IMAGE>

Title: Cutting device for a mobile lawn cutter
Inventor: DIESNER RICHARD
IPC: A01D34/73
Filed: 1983-09-07
Abstract: The invention relates to a cutting device for a mobile lawn cutter, having a holding disc which rotates parallel to the cutting plane and beyond the circumference of which movable cutting elements project. The object on which the invention is based is to design the lawn cutter for cutting widths in the region of 30 cm so as to be especially lightweight and at a low outlay and, at the same time, to allow an air guidance which improves the cutting operation and which brings about the conveyance of the cut grass to the discharge orifice. The solution is obtained in that the holding disc has towards the lawn surface a smooth essentially rotationally symmetrical face which is at an increased distance from the lawn surface in the middle region between the axle hub and the edge face, and in that, on the side of the edge face turned away from the lawn surface, flexible elongate cutting elements consisting especially of insulating material are mounted rotatably in the cutting plane. <IMAGE>

Title: Indexable insert with encircling chip-breaking groove
Inventor: FLAEMIG BARBARA
IPC: B23B27/14
Filed: 1983-09-14
Abstract: The invention relates to an indexable insert with encircling chip-breaking groove for metal-working, in particular for turning. The aim of the invention is to develop an indexable insert with a chip-breaking groove which, at a low level of deformation energy for the chip control, ensures reliable chip breaking to form chip particles suitable for transport. Starting from the known indexable inserts with encircling chip groove, the object of the invention is to develop a chip-forming and chip-breaking element which improves the chip breaking in a wide range of various chip widths and chip thicknesses. This object is achieved according to the invention by a corner-bead-shaped chip-breaking projection being arranged in the area of each corner radius of the cutting edges behind the rib formed by the inner groove flank of the chip-breaking groove symmetrically to the angle bisectors of the corner radii on the central surfaces running at an incline to the centre of the indexable insert. <IMAGE>
