Abstract: A percussive drill has a bit holder, a percussive drive including a ram slidably mounted in a hollow piston, and a drive transmission for reciprocating the ram in the piston via an air cushion. The forward travel of the ram during percussive action of the drill is limited by a drill bit or an intermediate member interposed between the drill bit and the ram. A member holds the ram in a position further forward, than that attained during the above limited travel allowed the ram, when percussive action is not desired. The holding member is resilient, has a U shaped cross-section, and is entered by the ram as it moves to the further forward position, the ram then forming a seal therewith, and the member also functioning to absorb the energy of an impact by the ram.

Abstract: Ein Elektromagnet zur Erzeugung des statischen Magnetfeldes für die NMR-Tomographie besteht aus einer zylindrischen Feldspule (1) und einem die Spule umgebenden und zugleich tragenden, stabilen Zylindermantel (4) aus Eisen. Die gegebenenfalls mehrteilige oder mit Korrekturspulen (2, 3) versehene Feldspule (1) erzeugt in dem von ihr definierten, zur Aufnahme des zu untersuchenden Körpers geeigneten Innenraum ein wenigstens annähernd homogenes Magnetfeld, dessen Homogenität wegen des streng symmetrischen Aufbaues der Anordnung auch bei Temperaturänderungen nicht gestört wird, und zwar selbst bei so großen Abmessungen, daß die Spule eine Aufnahme des menschlichen Körpers zuläßt. Der Zylindermantel (4) dient aber nicht nur als äußerst stabiles Tragelement, sondern bildet eine magnetische Rückführung, durch welche der Leistungsbedarf des Magneten bedeutend vermindert wird, sowie eine Abschirmung sowohl gegen äussere magnetische Felder und elektromagnetische Störstrahlung als auch gegen das Abstrahlen des bei der NMR-Tomographie erzeugten HF-Feldes. Der aus Eisen bestehende Zylindermantel (4) kann durch an dessen Enden angebrachte Ringscheiben (5) und Rohrstutzen (9) ergänzt oder sogar durch Eisendeckel verschlossen und dadurch in seiner Wirkung noch verbessert sein.
