Patent DE-3325098-A1 (DE)
Title: Triangular tennis racket frame construction
Inventor: ULBL JOHANNES
IPC: A63B49/02
Filed: 1983-07-12
Abstract: Only with this novel triangular tennis racket construction is it possible to win games from the base line of the tennis court with clear, but controlled off-the-frame shots since balls hit in such shots can no longer spring away from inner edges or outer curvatures of the racket frame, as a result of which a substantial feeling for the ball is obtained in order to place such off-the-frame shots accurately which may have been hit under pressure. The triangle in the acute-angled modification thus represents the optimum cross-sectional racket frame construction for the future of the sport of tennis.

Title: Folding roof for vehicles, in particular motor vehicles
Inventor: RITTER FRANK-RUEDIGER
IPC: B60J7/12
Filed: 1983-08-05
Abstract: In a folding roof for vehicles, in particular motor vehicles, having a front and a rear roof part, the rear roof part can be swivelled together with the front roof part into a folded-back countersunk position by means of parallelogram joint. The front roof part engages on the front edge of the rear roof part in a folding-back fashion. The joint parallelogram consists of a first linkage which connects the C pillar and a second linkage which is located behind the first linkage in the longitudinal direction of the vehicle, which linkages are coupled in each case to the vehicle body on the one hand and to the rear roof part on the other. The second linkage is divided in two by a toggle joint in such a way that it consists of a first part which is coupled to the vehicle body and a second part which engages on the rear roof part in an articulated fashion. Such a folding cover consists of few parts, is of lightweight construction and easy to actuate. It can be lowered in the open position below the main pivot point, i.e. the lower articulation point of the C pillar on the vehicle body, the lateral parts of the roof frame being capable of being fixed horizontally or in any desired oblique position and a vertical position. In the folded-together state, the folding roof is characterised in that it only requires a small amount of space.

Title: Method and device for monitoring the serviceability of a glow-discharge tube
Inventor: BARTELS FRIEDRICH
IPC: G01R31/24
Filed: 1983-11-17
Abstract: The method is used for monitoring the serviceability of a glow-discharge tube whose electrodes are connected to a voltage. The glow-discharge tube operates in accordance with a predetermined functional characteristic. When the glow-discharge tube is in an energised state, a current which terminates the energised state by reducing the voltage flows between the electrodes. The voltage (UB) is reduced during a monitoring time period ( DELTA T) to a magnitude which terminates the energised state according to the functional characteristic. During the monitoring time period ( DELTA T), the glow-discharge tube is monitored to determine whether a current is flowing between its electrodes counter to its functional characteristic. The monitoring time period ( DELTA T) can be selected during a functional phase during which a predetermined clock sequence of glow-discharges is occurring. The duration of the monitoring time period ( DELTA T) can be aligned to the duration of the functional phase. The device is used for monitoring the serviceability of a glow-discharge tube whose electrodes are connected to a voltage. When the glow-discharge tube, which is operating in accordance with a predetermined functional characteristic, is in the energised state, a current flows between the electrodes. The current terminates the energised state by reducing the voltage. A transistor is provided in a supply lead which is connected to the electrodes, which transistor reduces the voltage applied to the electrodes to a level at which ...   Original abstract incomplete.
Patent DE-3341928-A1 (DE)
Title: Cross-winding device
Inventor: SCHMIDT WERNER DIPL ING
IPC: B65H54/48
Filed: 1983-11-21
Abstract: In a cross-winding device with pre-traversing by a traversing yarn guide driven by reversible threaded shaft and moving to and fro, and with post-traversing by a grooved roller having an endless intersecting yarn-guide groove, the middle region of the grooved roller has a smaller radius than the end regions. The radius of the grooved roller in the middle region is reduced at most to such an extent that the groove bottom is still preserved. The end regions having a larger radius extend from the stroke reversal in the direction of the stroke middle over the range of the traversing stroke, in which the traversing yarn guide moving to and fro is driven at a non-uniform speed and the yarn is guided by the flanks of the yarn-guide groove. The end regions can also extend as far as the respective first intersection of the yarn-guide groove. As a result of the measure indicated, the noise generation of the cross-winding device caused by the yarn-guide groove is reduced.

Title: Cutting and feeding device for a drawn machine or a machine provided for three-point mounting on the tractor for the harvesting of maize or suchlike stalk-like crops
Inventor: KRONE BERNARD
IPC: A01D43/08
Filed: 1984-02-23
Abstract: In a cutting and feeding device for a drawn machine or a machine provided for three-point mounting on the tractor for the harvesting of maize or suchlike stalk-like crops, having a continuous pick-up edge, countercutters are arranged, in conjunction with holding fingers and stays, on the said pick-up edge. The countercutters together with the holding fingers and/or the stays are fastened in a rotationally removable and controllable manner in receiving bores in the circumferential region of the pick-up wheel. Arranged underneath the pick-up wheel and the countercutters is an arcuate stationary cutting knife, over which the countercutters sweep during their movement together with the pick-up wheel. This ensures that, when the machine is working, the crop is cut off at any point of the working range of the cutting knife, is held above the cutting point by one of the holding fingers and one of the stays and, while being released at the same time, can be fed, approximately vertically or at an inclination opposite to the conveying direction, to a following chopper blower.

Title: Boundary-layer suction without motor-driven units for winged aircraft
Inventor: AGETHEN FRANZ ALBERT
IPC: B64C9/24
Filed: 1984-04-03
Abstract: An aircraft according to the patent application is an amalgamation, without any compromises, of a fast aircraft and a very slow aircraft, as becomes evident from the four claims and the description. In the case of a very small aircraft, a speed ratio of even 10:1 is possible, as a 2m model built in 1940 showed, in 1941, with a ratio of 371:37 kph (anti-aircraft gun observer, West Cologne). 1.) The reduced-pressure flow does not separate. Where a conventional aircraft reaches the critical speed immediately before landing, it must land! At this time, an aircraft according to the patent application still has somewhat more than three times the lift! That is not all. In addition: 2.) Increase in the wing area by virtually 50%! 3.) A higher angle of attack is possible, because there is no longer any critical speed. The advantages of a landing path reduced by 70-80%, that is to say to approximately a quarter, are self-evident. However, with less than 6 seats, the cost is too great, and four-seater aircraft uneconomically rarely have a landing speed over 100 kph. The limit is difficult to draw here, since a six-seater aircraft with suction manages even at around 50 to 60 kph. This category would be the highlight in the "third world", and primarily in Canada, up to the shuttle, as recognised specialists have told me.

Title: Self-cleaning liquid-filled radiator
Inventor: SCHMITT HELWIG DIPL ING
IPC: F01P11/12
Filed: 1984-05-07
Abstract: Close-meshed liquid-filled radiators of tractors and similar machines become contaminated rapidly when working in air that is dust-laden or enriched with plant parts, and must be cleaned frequently by the driver. Clogged liquid-filled radiators represent a substantial source of risk to the engine. It is the object of this invention to indicate solutions by means of which it is possible to prevent liquid-filled radiators from becoming blocked and/or to clean blocked liquid-filled radiators by means of the cooling air sucked in by the fan. Represented in Figure 1 is a liquid-filled radiator (1) which is surrounded by a circumferential recticular fabric (2), so that on the side (2a) of the fabric (2) that is averted from the fan (3), the foreign bodies mixed in with the cooling air are captured and filtered out and transported by the fabric (2) around the liquid-filled radiator (1) and subsequently sucked off from the side (2b) of the fabric (2) facing the fan (3). Represented in Fig. 3 and in Fig. 4 is a further liquid-filled radiator having an auxiliary device which periodically circulates the cooling air in such a way that the flow through the liquid-filled radiator (1) is in the opposite direction, and thus the deposits of foreign bodies in and in front of the radiator grid are blown out. In this case, the cooling air continues to be sucked through an air filter, possibly connected upstream. <IMAGE>

Title: Electronics-compatible switching device for an electromagnetically operable switching apparatus, especially a contactor, and a method for its assembly
Inventor: LIEBISCH RUDOLF DIPL ING
IPC: H01H71/46
Filed: 1984-05-23
Abstract: The object of the invention is an electronics-compatible switching device for an electromagnetically operable switching apparatus, especially a contactor having a high switching-point accuracy, high contact safety when switching small voltages and currents, and short contact-bounce times, which can be combined with conventional current tracks and in which the assembly of the protection-tube contact and its connecting and joining technology require no additional devices, a reliable installation position of the protection-tube contact having to be ensured. The solution according to the invention is for an assembly to be inserted into the switching chamber of the auxiliary switch housing of a contactor, which assembly consists of a protection-tube contact holder in which a protection-tube contact is inserted in a positively-locking and force-fitting manner by means of the connecting ends which are constructed as contact springs and their connecting ends which are constructed as spring clips. The two outer conventional current tracks of the auxiliary switch are in each case replaced by such an assembly. They are operated by means of permanent magnets which are arranged in the crossbar of the auxiliary switch module. The field of application of the invention is electromagnetically operable switching apparatuses, especially contactors, whose contacting devices ensure the switching of small voltages and currents with high contact safety, and which can be used as a coupling element between conventional switching apparatuses and electronic control devices. <IMAGE>

Title: Clutch control for motor vehicle
IPC: B60W30/18
Filed: 1984-06-08
Abstract: A clutch control for a motor vehicle with automatic range transmission is proposed. A range-change shift (10) is inserted between an accelerator pedal (6) and a speed governor (5) for the engine (1). This shift can be operated by the driver. By means of the range-change shift (10), the signal of the accelerator pedal (6) can be isolated from the speed governor (5) and directed by way of a servo control (11) to a servo motor (8) for operating the clutch (2). At the same time the speed governor (5) is set permanently to the idling speed of the engine (1). By operating the accelerator pedal (6) it is thereby possible to control the clutch (2). In this way crawling speeds of the vehicle which lie below the idling speed can be set. <IMAGE>

Patent DE-3433001-A1 (DE)
Title: Single-bar connection
Inventor: SEIZ RUDOLF
IPC: E21D11/28
Filed: 1984-09-07
Abstract: The invention relates to a single-bar connection for the longitudinal chords of lattice-like segments for tunnel support frames, in which the chord end has a coupling section provided with a hook, as well as an end section which is provided with two legs and is firmly connected to the coupling section, which, by a common screw bolt, can be held together with the coupling section of the mating hook which can be brought into positive-locking engagement with this hook. This connection is to be designed in such a way that an even better coupling of the coupling sections to be connected to one another is obtained with regard to the flexural rigidity and tensile strength, in which coupling the forces are directed in the bar plane so that no additional moments occur during tension and compression, as a result of which the capacity for load transmission between the longitudinal chords to be connected to one another is increased without the material sections having to be enlarged. This object is achieved in that the coupling section of the mating hooks is a separate plate-shaped body not connected to the end section, and the two legs of the end section form at their front end a curved piece which connects them, can be inserted into the hook and mating hook and can be clamped in place by the screw bolt.

Title: Method for producing a coding rule
Inventor: DIEDERICH HANS G DIPL ING
IPC: H04W12/00
Filed: 1984-10-20
Abstract: In a telecommunications network, especially a cellular mobile-radio network, it is intended to produce a coding rule which is used for the selection of one of a plurality of codes which are to be kept secret and are stored with the subscribers. Since at least one control centre always transmits different signals to all the associated subscriber apparatuses for operation handling, irrespective of the direction in which the connection is set up (initiated by the subscriber apparatus or arriving at said apparatus), according to the invention, these signals are subjected in all the subscriber apparatuses to additional evaluation with respect to the number and type of signalling processes within an agreed time interval. The result is then used as a coding rule. Its transmission remains concealed from an unauthorised user. <IMAGE>
