Patents
Search within the title, abstract, claims, or full patent document: You can restrict your search to a specific field using field names.
Use TI= to search in the title, AB= for the abstract, CL= for the claims, or TAC= for all three. For example, TI=(safety belt).
Search by Cooperative Patent Classifications (CPCs): These are commonly used to represent ideas in place of keywords, and can also be entered in a search term box. If you're searching forseat belts, you could also search for B60R22/00 to retrieve documents that mention safety belts or body harnesses. CPC=B60R22 will match documents with exactly this CPC, CPC=B60R22/low matches documents with this CPC or a child classification of this CPC.
Learn MoreKeywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.
Learn MoreChemistry searches match terms (trade names, IUPAC names, etc. extracted from the entire document, and processed from .MOL files.)
Substructure (use SSS=) and similarity (use ~) searches are limited to one per search at the top-level AND condition. Exact searches can be used multiple times throughout the search query.
Searching by SMILES or InChi key requires no special syntax. To search by SMARTS, use SMARTS=.
To search for multiple molecules, select "Batch" in the "Type" menu. Enter multiple molecules separated by whitespace or by comma.

- -^ HOE 79/F 308Patentansprüche:( 1.)Verfahren zum Regeln des Durchflusses einer Kreiselpumpe mit bekannten Kennlinien, die von einem drehzahlveränderlichen Motor angetrieben wird, dadurch gekennzeichnet, daß man Drehzahl- und Leistungsaufnahme der Kreiselpumpe mißt, mit dem gemessenen Wert den Durchfluß der Pumpe aus ihren Kennlinien ermittelt, diesen mit dem Sollwert für den Durchfluß vergleicht und in an sich bekannter Weise den Motor der Pumpe verstellt.
- 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß man Drehzahl- und Leistungsaufnahme der Pumpe unter Berücksichtigung von Schlupf- und Wirkungsgrad aus der gemessenen Drehfrequenz und Leistungsaufnahme des Motors ermittelt.130022/0196
