Abstract: Bei einem Zweiwegentfernungsmeßsystem (Sekundärradarsystem) werden von einer Abfragestation impulsförmige Abfragesignale zu einer Antwortstation gesendet, die nach einer vorgegebenen Zeit nach Empfang eines Abfragesignals ein impulsförmiges Antwortsignal abstrahlt, das von der Abfragestation empfangen wird. In der Abfrage und in der Antwortstation werden aus den impulsförmigen Signalen zu bestimmten Zeitpunkten Triggersignale abgeleitet. Abweichungen der Impulse von ihrer Sollform (z.B. verursacht durch Gerätetoleranzen, Mehrwegausbreitungen) haben zur Folge, daß die Triggerzeitpunkte für die Entfernungsmessung falsch sind. Deshalb werden in der Abfrage- und/oder der Antwortstation mindestens ein Teil des Amplitudenverlaufs oder typische Parameter (Anstiegszeit ts) eines Referenzimpulses gemessen. Als Referenzimpuls wird der abgestrahlte, ungestörte Sendeimpuls verwendet, dessen Daten zur jeweils anderen Station (Abfrage- oder Antwortstation) digital übertragen und gespeichert werden. Von dem jeweils empfangenen Impuls werden entsprechende Werte (tr) ermittelt (13) und mit den gespeicherten verglichen. Aus diesem Vergleich werden Korrekturwerte (tk) für die Triggerzeitpunkte abgeleitet.

Abstract: This invention is directed to a rubber skim stock and a product containing the skim stock having improved adhesion between a brassed or zinc coated metal member and contiguous rubber skim stock. The invention lies in the discovery that improved rubber-to-metal adhesion, and adhesion retention, can be obtained by adding to an otherwise conventional rubber skim stock composition appropriate amounts of cobalt propionate. 
     In the practice of this invention, cobalt propionate is mixed into a rubber skim stock composition, which composition is brought into contiguous relationship with a brassed or zinc coated metal member in the unvulcanized composition followed by vulcanization to yield the end product.

IPC: B63H9/06
Filed: 1982-12-15
Abstract: A sail with a tubular portion is pulled over a mast and/or a stay of a sailing vessel. The tubular portion is inflatable through a sail mouth opening at the fore leech thus forming an air envelope of the sail due to the relative wind effects. A plurality of telescoping contour sleeves formed of a lightweight, floating, elastic material are arranged in the tubular portion and sheath the mast and/or stay as well as selected portions of the rigging. The formation of an air envelope from a part of the sail and the use of rotatable streamlined contour sleeves inhibit complete heeling over of the sailing vessel and simplify the erecting of surfboards and sailboats. The telescoping arrangement of the contour sleeves permits an alteration of the sail surface and the sheathing of the rigging further decreases the wind resistance leading to an increased speed capability without need for greater inclination of the vessel. Thus the sails are better able to utilize the wind energy.

Abstract: The invention relates to a system for feeding single bags to automatic bag inserting apparatuses, picking them up and also unsticking the bag being picked up from the underlying ones, in case they are glued to one another because of glue drops during the bag manufacture. The system substantially comprises (see FIG. 3) three units: a first unit provided with suction cups, picking up the bag at its transversal middle portion, where accidental adhesion of bags cannot happen, and lifting it to allow that two unsticking units, including bars being inserted under the bag and unsticking it from the underlying one with a spreading action, are inserted between said bag being picked up and the underlying one. One of the two units is also provided with pincers blocking the bag edges on the open unsticking arms and, in the return stroke of the unit to the starting position, transferring it on to the feeding device of the bag inserting apparatus. The other unsticking unit is so arranged that the two unsticking bars, in addition to the spreading action, are lowered so as to press the underlying bags so as to hold them down during the stage of bag picking by said pincers of the first unsticking unit, so that, if the unsticking was not complete, the underlying bags are kept blocked down and the bag being picked up is stripped and finally separated from the others.

Abstract: An improved cassette hub locking mechanism comprising in one embodiment a hub including a locking flange between a web-carrying portion of the hub and a bottom housing member of the cassette. Spring means urges the hub toward the bottom member and locking means between the locking flange and the bottom member prevents rotation of the hub when the locking flange and hub are engaged. Another embodiment of the locking mechanism Includes a hub and a locking member between the hub and a top member of the cassette. Spring means urges the locking member into engagement with the hub to lock the hub and a play/ record apparatus spindle inserted into the hub abuts the locking member to disengage the locking member and the hub, thereby allowing rotation of the hub. in a further embodiment a gear cooperates with a housing member and functions as a locking member as well as a driving member. A spring urges gear into a locking position but is released when the cassette engages a part of an associated cassette record or play apparatus.

Abstract: A combined unloader and pressure relief valve for a hydraulic system comprises a main valve member (13) the opening of which is controlled by pressure in a pilot valve chamber (23). A lever (28) is normally held against a stop by a spring (31) and rests lightly on a pilot valve member (27) which thus maintains a low pressure in chamber (23) allowing the main valve to open under the influence of pressure at Inlet (4). When the valve is to be closed to charge an accumulator (8) a transducer (10) energises a coil (37) to pivot lever (28) about pilot valve member (27). This lifts the lever from the stop and applies a spring load to the pilot valve member thereby allowing pressure to build in chamber (23) to close the main valve member. If the transducer (10) fails and maintains the coil (37) permanently energised, the main valve member will act as a pressure relief valve since the pilot valve member will lift when pressure in chamber (23) is able to overcome the applied spring load.
