[Josef Katona] DEX Friedrichshafen A transducer to be used in a shock wave generator including a support, at least one energizing coil mounted on the support; at least one, preferably two copper or silver membranes are placed on the coil and insulated from each other; an outer, stainless steel membrane is grounded and an electrical insulation is interposed between the first and the second membranes.

[Kenneth A. Jacobson, John W. Daly, Kenneth L. Kirk] DC Washington This application discloses probes for adenosine receptors which are functionalized congeners of the following compound: wherein R is --CH.sub.2 --C(O)--R' or These probes bind to A.sub.2 and A.sub.3 adenosine receptors and aid in quantifying and characterizing the receptors. The compounds may be labeled, for example with fluorescent compounds or radioactive compounds, or unlabeled.

[Craig D. Oster] MN St. Paul A heater assembly for a hot melt applicator includes a heating block having a melting chamber and two compartments receiving a pair of elongated heating elements along opposite sides of the chamber. The heating elements have respective longitudinal axes that lie in a common plane which extends toward an outlet of the melting chamber at an angle relative to a central axis of the melting chamber. In preferred forms, the longitudinal axes of the heating elements converge toward each other as the outlet of the melting chamber is approached.

[Edwin Seitz] DEX Kommanditgesellschaft Disclosed is an outside rear-view mirror for a vehicle, having a mirror base and a mirror housing which is adapted to assume a normal position for use relative to said mirror base and to rock forwardly and rearwardly and which is coupled to said mirror base by a rocker. To reduce the danger of injuries particularly of fingers, caused by a back-swinging mirror housing between said mirror housing and said mirror base, at least one spreading spring is provided one end of which abuts said mirror housing and the other end of which abuts said mirror base, and which urges said housing to a fully backward tilted position relative to said mirror base.

[Rolf Jung] DEX Stuttgart In order to achieve exact positioning of a leading edge of a fabric web in a fabric web guide of a fabric spreading machine, it is suggested for a method and apparatus that the fabric web is moved forward with its leading edge in the direction of spreading up to the starting line, the leading edge is then detected and the fabric web slowed down and stopped, that after stopping it is determined whether or not the leading edge coincides with the starting line, and that when the leading edge does not coincide with the starting line the fabric web is withdrawn contrary to the direction of spreading for a predetermined distance and then moved forward again in the direction of spreading up to the starting line.

[Kimitoshi Shin, Yukiko Okumura] JPX Kawasaki A data error detecting method and system which can detect whether or not there occured an error in data stored in a memory of a computer system or the like. A new error check sign is introduced in addition to a prior art check sum sign to detect the data error on the basis of the both signs. The new error check sign is generated by applying weights that are different for different addresses in each of data blocks to the associated numbers of "1's" or "0's" of data stored at the addresses, multiplying the values of the addresses to the associated weighted numbers of "1's" or "0's" and then adding the multiplication results together.

[John F. Knifton, Wei-Yang Su] NY White Plains This invention is directed to novel phosphorus-free catalyst compositions based on titania pellets on which a minor amount of a tungstosilicic acid or a molybdosilicic acid is deposited. Also, the invention is directed to a process for preparing predominantly linear polyethylenepolyamines from ethylenediamine and monoethanolamine using the novel catalyst compositions.
