Patent DE-3236836-A1 (DE)
Title: Hydroplane
Inventor: JANSEN DIETER
IPC: B63B1/12
Filed: 1982-10-05
Abstract: A motor-driven hydroplane is described, the hull of which has three keels at the bow which, tapering towards the stern, form buoyancy chambers between them, the outer sides of which are defined by keels forming aprons, the keel arranged in the centre being connected to the lateral aprons by curved surfaces which deflect the spray towards the stern. To protect against spray, the propulsion element, preferably a two-bladed propeller, is arranged in a tunnel. The novel hydroplane is distinguished by improved planing properties and improved motion resistance.

Title: Reproducing apparatus for acoustic information
Inventor: WIESNER MICHAEL
IPC: G11B7/003
Filed: 1983-06-16
Abstract: The invention relates to an apparatus for reproducing permanently stored but replaceable acoustic information on optical sound tracks which lie in parallel next to one another and each track is assigned a photo sensitive element. The object of the invention is to have immediate access to a particular selected item of information from a finite number of stored information items without time loss and to listen to the said information in high sound quality. The desired items of information are stored inexpensively on an optical sound carrier as an optical sound track in parallel next to one another, scanned contactlessly and consequently without wear from the moving optical sound carrier by means of a light beam and transmitted to photo sensitive elements, which are assigned to each track, converted there to electric pulses and made audible by means of a suitable amplifier. A suitable controller handles selection of the information. By this useful novel arrangement of known techniques such as optical sound, photoelements and their activation by microelectronics, the reproducing apparatus can reproduce acoustic information of high sound quality inexpensively and without time loss.

Patent DE-3334803-A1 (DE)
Title: Holder of a lowerable luminaire cover
Inventor: BRUEGGEMANN JUERGEN
IPC: F21V17/16
Filed: 1983-09-26
Abstract: It is occasionally impossible for design reasons to pivot the luminaire cover (e.g. the louvre) directly out of the housing. In these cases, the cover is firstly drawn downwards vertically and then held on the housing by springs. The subject matter of the invention is a holder which permits the cover (3) to be withdrawn, as well as permitting it to be subsequently pivoted away and also permitting complete detachment in which a proper chassis earth connection between the cover and housing is always guaranteed. This purpose is served by an approximately M-shaped support spring (4) which is guided in the luminaire housing (1) and is coupled to the edge region of the cover (3) by means of angled bearing arms (411). <IMAGE>
Patent DE-3338658-A1 (DE)
Title: Device for co-ordinate transformation when controlling rotating-field machines
Inventor: ZIMMERMANN WERNER DIPL ING
IPC: H02P21/06
Filed: 1983-10-25
Abstract: When using rotating-field machines in highly dynamic drives, the principle of "field-oriented control" has been proven. In this method, it is necessary to transform time-variable parameters between reference co-ordinate systems which rotate with respect to one another. While these transformations were originally implemented using purely analog circuit technology, microcomputers are now generally used, because of the drift and accuracy problems. However, their computation speed is frequently not adequate in the case of fast-running machines. The device according to the invention, which is shown by way of example in Fig. 4, avoids these disadvantages. The orthogonal components xd and xq of the parameter to be transformed are applied to the reference signal inputs (11) of multiplying digital/analog converters (12), (13), (15) and (16). The sine and the cosine of the instantaneous angle  phi  between the co-ordinate systems are applied to their digital inputs (14). The output parameters (10) of the co-ordinate transformation device (5), which are likewise orthogonal, are formed by means of summation (18), using the correct mathematical sign, of in each case two of the output parameters (19) of the multiplying digital/analog converters (12), (13), (15) and (16). Using this device, it is possible at a low cost to transform parameters between co-ordinate systems which rotate very quickly with respect to one another, virtually without any delay. <IMAGE>

The pipe piece (18) projects in the axial direction beyond the deformation zone (12) on both sides, is firmly connected at one end to the shell (10) in an annular region (20) and forms an annular gap (24) with the shell (10) at the other end. The pipe piece (18) stiffens the shell in the region of the deformation zone (12) at high speeds. <IMAGE>

Abstract: Front-loader flat-silo cutter, in which a motor-driven cutting roller is mounted on a holding frame which is itself fastened to a front-loader shovel. The front-loader shovel is fastened tiltably to the ends of pivotable front-loader rockers. The holding frame of the cutting roller is fastened to the front-loader shovel via connecting elements, in such a way that the cutting roller projects above the top edge of the front-loader shovel and, with the front-loader shovel tilted down completely, is further away from the axis of rotation of the front-loader rockers than the front-loader shovel. Moreover, the cutting roller is seated so near to the rear wall that the front-loader shovel can be loaded by the cutting roller essentially without disturbances.

Title: Articulated road train
Inventor: STEINWINTER MANFRED
IPC: B62D13/00
Filed: 1984-02-11
Abstract: The articulated road train has a towing vehicle and a trailer which has at least two axles with wheels and is coupled to the towing vehicle via a coupling device. Here, at least the front axle of the trailer is constructed for the purpose of steering the wheels as a trailing axle and the front part of the coupling shaft is coupled to the bearing block of the towing vehicle so as to be swivellable about a vertical axis for the purpose of lateral deflection. The coupling shaft is additionally arranged separately from and independently of the trailing front axle on the trailer, specifically in such a way that, with its rear end, the shaft is attached to the frame so as to be rigid to resist lateral swivelling out and so as to be able to swivel exclusively about a transversely extending horizontal axis.

Title: Anti-skid chain for vehicle wheels, in particular track-crossing chain, and method for its manufacture
IPC: B60C27/14
Filed: 1984-03-09
Abstract: In the anti-skid chain for vehicle wheels having a holding ring (1) arranged on the inside of the tyre and made of spring steel wire, the closure eye (6) of the hook closure (2) has a free end leg (7a) which is bent back in parallel with the holding ring (1), and the fixed run-up slope or run-up path (8) for the closure hook (6) is part of a funnel-shaped half shell (20) which has an insertion slot (23) for the closure hook (6), which slot is directed from the inside of the holding ring (1) to the closure eye (7) and receives a section of the holding ring with the parallel end leg (7a), lying against it, of the closure eye (7), directly behind the closure eye (7) in a holding sleeve (21) which is formed out in one piece on the half shell (20) and has an oblong hole (22). A particularly easy handling and good cleaning effect is also produced by virtue of the fact that the run-up path (8) on the funnel-shaped half shell (20) is directed from the inside of the holding ring (1) in a characteristic curve which rises approximately in a parabola towards the end (7b) of the closure eye (7). The invention also permits a particularly advantageous method of manufacturing anti-skid chains of this kind. <IMAGE>

Title: Device for discharging cuttings from the auger of an auger drilling appliance for earth bores
Inventor: BAUER KARLHEINZ DR ING
IPC: E21B12/06
Filed: 1984-12-21
Abstract: In a device for discharging cuttings from the auger of an auger drilling appliance for earth bores, provision is made for the device to have a rotary ring arranged coaxially about the auger and having a clearing blade. The rotary ring and the clearing blade are rotated about the auger during extraction of the auger so that the clearing blade, which is in engagement with the auger, releases the cuttings located in the auger. It is thus possible, even during a purely translatory extracting movement of the auger out of the borehole, to discharge the cuttings in the auger as completely as possible.
