Title: Suspension for the cab of an agricultural vehicle
Inventor: IPPEN HEIKO
IPC: B62D33/06
Filed: 1993-06-25
Abstract: It is known to place a cab of an agricultural vehicle, in particular a tractor, on the body of the vehicle via rubber bearings. This cab, which forms a separate constructional unit, is, as a result, largely insulated from the body and from interference frequencies originating therefrom. The invention is based on the object of connecting or mounting a driver's platform, in particular a cab, of an agricultural or constructional vehicle in such a manner to the body of the vehicle that the comfort of the vehicle driver is improved, the connection and mounting being carried out in a structurally simple and effective manner. The object is achieved by virtue of the fact that at least two actuators are arranged between the driver's platform and the body, and that the vehicle has sensors for detecting the position of the vehicle or the driver's platform, a control unit being provided in the vehicle, which control unit operates the actuators as a function of the position detection. <IMAGE>

Title: Process and apparatus for the continuous fluorination of webs of plastic
Inventor: JONDA MICHAEL DIPL ING
IPC: B29C37/00
Filed: 1993-07-15
Abstract: In a process and an apparatus for the continuous fluorination of webs of plastic, in particular continuously extruded sheets of plastic, studded sheets, foams, chopped strand mats etc., in which the material to be fluorinated is passed through a treatment chamber 15 with a partial pressure of the fluorine-nitrogen mixture, upstream and downstream of which there is at least one transfer chamber 16, 17, 18, 19, the partial pressure is reduced in the in each case at least two provided transfer chambers 16-19 from the range of highest concentrations in the treatment chamber 15 by selective leakage into lower concentrations for the respective transfer chambers 16-19 with respect to the atmosphere, each transfer chamber 16-19 having pneumatically controllable sealing profiles for sealing it off. In the run-in transfer chamber, at the same time a prefluorination of the web material is made possible in addition to cleaning, the legally stipulated values for the maximum allowable concentrations at the run-in and run-out of the apparatus 10 being maintained safely and reliably. <IMAGE>

Title: Hovering vehicle for roads and rail
Inventor: SCHAPER RUDOLF
IPC: B61B13/08
Filed: 1993-09-13
Abstract: The invention relates to a so-called hovering vehicle for roads and/or rail, characterised in that a relatively large wing is mounted on the vehicle roof or the entire passenger compartment is shaped to form a wing, and in that the passenger cabin which hovers as a result is coupled by a suspension device to a rail or road vehicle (without passenger cabin). The invention has the following advantages: After it reaches the hovering state the hovering passenger cabin decreases the weight of the entire vehicle by approximately 50%. In the case of unevennesses, bends and in particular positive and negative gradients of the rail track, the travel speed no longer needs to be decreased. Moreover, fuel is saved. Within the context of reducing the weight of the entire vehicle, laying the rail for this railway on elevated carriers (elevated railway) in order to span roads and difficult, also mountainous, terrain becomes economically viable, since the rail carriers no longer have to be designed for extremely heavy railway trains.

Patent DE-4339688-A1 (DE)
Inventor: BECKHAUSEN KARLHEINZ
IPC: B60J10/00
Filed: 1993-11-22
Abstract: Known safety contact rails have a securing strip (1), a sheath part (3) and an inner element (5) arranged therein. In this arrangement, the inner element (5) and the sheath part (3) are designed to be electrically conductive and, in the case of mutual contact, trigger a switching pulse which can be fed to an evaluation unit. As a result of the electrically conductive construction, the sheath part can be more easily damaged than other parts and can also effect false triggering. Since, as a result, the surface is also electrically conductive, the accidental transfer of voltage to control units connected downstream is also possible. As a result of coating the sheath part (3) with an electrically non-conductive outer protective layer (6), which is preferably produced by means of extrusion together with the securing strip (1), the inner element designed as a knife-like rib (5) and the sheath part (3), faulty triggering as a result of, for example, contamination of the sheath part (3) is excluded. Likewise, the protective layer (6) can be deliberately designed to be resistant to specific damaging surface influences, which can for example be given by acids, without the electrical conductivity of the sheath part (3) being influenced in a disadvantageous manner. <IMAGE>

Title: Determining mutual proximity of two objects, for collision avoidance
Inventor: KAYSER WERNER DIPL ING
IPC: G01B7/00
Filed: 1993-12-02
Abstract: At least from a critical approach of the first and second objects (1, 2) being protected or a mutual approach of the objects results. The electrical resistance between the surfaces (5, 6) serves as a measure for the mutual approach of the objects. A variable electrical potential difference is produced between the first surface (5) of the first object and the second surface (6) of the second object. An alteration of the potential difference serves as a determination variable for the resistance.

Title: Injection core for two-component injection moulding
Inventor: SCHELLENBACH FRANK
IPC: B29C45/10
Filed: 1988-06-03
Abstract: An injection core for two-component injection moulding, in particular of plastic stoppers for bottles and similar containers, solves the problem caused by the fact that injection cores in a single piece can only be moved with difficulty, if at all, a predetermined distance away from the first injected body, because of the design of the latter, in order to create a gap for injecting the second body. The injection core is composed of a first (1) and of a second (2) partial cores. The first partial core can be moved a predetermined distance (A, A') away from the first injected body after injecting the first substance, and the second substance can then be injected in the gap thus obtained in order to form the second injected body.

Abstract: Die Erfindung betrifft ein Verfahren zum Trennen eines Zylinders mit Verbrennungsaussetzern von der Kraftstoffzufuhr in einem Verbrennungsmotor. Die Verbrennungsaussetzer können auf beliebige bekannte Weise detektiert werden. Nach dem Abschalten der Kraftstoffzufuhr wird überprüft, ob sich der Wert von Aussetzerinformation gegenüber dem Wert vor dem Abschalten geändert hat. Wird keine wesentliche Änderung festgestellt, bleibt die Kraftstoffzufuhr abgeschaltet. Bei einer wesentlichen Änderung wird dagegen der betroffene Zylinder wieder so lange mit Kraftstoff versorgt, bis erneut Verbrennungsaussetzer in diesem Zylinder erkannt werden. Dieses Verfahren hat den Vorteil, daß die Maßnahme des Abschaltens der Kraftstoffzufuhr ohne langwierige Vorabprüfungen sehr schnell erfolgen kann, daß aber dafür gesorgt wird, daß diese schnell getroffene Entscheidung wieder rückgängig gemacht wird, falls sich herausstellt, daß sie voreilig und falsch erfolgte.

Abstract: Dans les appareils de commutation où les contacts sont établis par actionnement d'une armature battante, la vérification peut comprendre une analyse de vibrations ou de l'émission de son survenant dans des conditions de service. Selon l'invention, le son émis lors de l'actionnement de l'appareil de commutation est identifié par un détecteur, puis transmis à une unité d'exploitation en vue de la discrimination de la courbe-temps et/ou de fréquence des composantes du son. Le procédé proposé permet notamment de discriminer les signaux sonores générés d'une part par les contacts et d'autre part par l'armature. De plus, une analyse du son effectuée dans une plage temporelle appropriée permet d'établir une classification des pannes pouvant intervenir dans l'appareil de commutation. Finalement, il est possible de déterminer de manière objective la bonne sonorité d'un relais, tout particulièrement lors de l'utilisation appliquée aux relais clignotants. Dans tous les cas de figure, ce sont surtout les composantes élevées du son qui font l'objet d'une évaluation.
